45/60 and 10/60 because we know that the common denominator is 60 then 3/4 of an hour is 45mins then 1/6 of an hour is 10
By finding common denominators, we can express the boat drawbridge opening times in terms of a shared timeframe, such as every 60 minutes or 30 minutes. The common denominator is the smallest number that the opening times can be equally divided into.
Explanation:The question relates to the application of common denominators in the context of timekeeping. Without specific times for the opening of Colby and Wave drawbridge, I will give a hypothetical scenario as an example.
Let's say Colby drawbridge opens every 20 minutes and Wave drawbridge opens every 15 minutes. A common denominator of 20 and 15 is 60, as they both divide evenly into 60. So, you could rename the opening times in terms of 60 minutes: Colby drawbridge opens 3 times every 60 minutes (60/20) and Wave drawbridge opens 4 times every 60 minutes (60/15).
If we want to use another common denominator, you could use 30. Then Colby drawbridge opens 1.5 times every 30 minutes (30/20) and Wave drawbridge opens 2 times every 30 minutes (30/15).
The way to find common denominators involves looking for the smallest number that both of the numbers can divide equally into. In this case, 60 was an obvious choice since there are 60 minutes in an hour, but other common denominators like 30 can also be used.

To make circular cake boards, a company cuts circles out of plastic squares. The circles are cut as wide as the squares to lessen the amount of wasted material. Use the drop-down menus below to complete statements about the amount of wasted material for circular cake boards with a diameter of d.
The area of the wasted material is given by the difference:____-______
d^2
4d
π(d/2)^2
Answer:
d^2 - π(d/2)^2
Step-by-step explanation:
Since the diameter of the circle is equal to the side of a square (d), that means that we have a circle inscribed in square.
If we draw a square and inscribe a circle in it, all parts of the square outside the circle will be waste, in this particular case.
If we want to find the area of the wasted material we need to subtract the area of the circle from the area of the square.
Area of the circle is:
P1 = πr^2, r being the radius
Since radius is half the diameter, that means that:
P1 = π • (d/2)^2
Area of the square whose side is d is:
P2 = d^2
So, the area of wasted material is:
P = P2 - P1
P = d^2 - π(d/2)^2

5x - y = 3.......(1)
2y = 10x+2.....(2)
Rearranging (2)
-10x + 2y = 2......(3)
Multiply equation (1) by 2

Suppose that the probability that a person will die in the next 20 years is
7.2698%. If this person has a life insurance policy that will pay out $60,00
the beneficiaries of the policy if the person dies in the next 20 years, what is
the premium of the policy? Assume that the administrative costs of the policy
amount to $75.
The premium of the policy is approximately $64,198.32.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To calculate the premium of the policy, we need to take into account the probability of the person dying in the next 20 years and the payout of the policy.
Let P be the probability of the person dying in the next 20 years, and let A be the administrative costs of the policy.
Then the expected value of the payout of the policy is:
E(payout) = P x $60,000
And the expected value of the cost of the policy (including administrative costs) is:
E(cost) = P x premium + A
We want to find the premium of the policy, so we can rearrange this equation to solve for the premium:
premium = (E(cost) - A) / P
Substituting the given values, we get:
P = 0.072698
A = $75
E(payout)
= P x $60,000
= 0.072698 x $60,000
= $4,361.88
Now we need to calculate the expected value of the cost of the policy.
The cost of the policy includes both the payout (if the person dies) and the administrative costs (whether or not the person dies).
So we can write:
E(cost) = E(payout) + A x (1 - P)
where (1 - P) is the probability that the person will not die in the next 20 years.
Substituting the given values, we get:
E(cost) = $4,361.88 + $75 x (1 - 0.072698) = $4,746.88
Finally, we can calculate the premium of the policy:
premium = ($4,746.88 - $75) / 0.072698 = $64,198.32
Therefore,
The premium of the policy is approximately $64,198.32.

The 4th term of an arithmetic sequence is 12 and the 8th term is 36. Find the 17th term of the sequence.
How do you work it out?
Answer: 90
Step-by-step explanation:
The formula for calculating the nth term of a sequence is given as :
[tex]t_{n}[/tex] = a + ( n - d )
Where a is the first term
d is the common difference and
n is the number of terms
This means that the 4th term of an arithmetic sequence will have the formula :
[tex]t_{4}[/tex] = a + 3d
And the 4th term has been given to be , 12 ,substituting into the formula we have
12 = a + 3d .............................. equation 1
Also substituting for the 8th term , we have
36 = a + 7d .............................. equation 2
Combining the two equations , we have
a + 3d = 12 ................... equation 1
a + 7d = 36 ------------ equation 2
Solving the system of linear equation by substitution method , make a the subject of formula from equation 1 , that is
a = 12 - 3d ................... equation 3
substitute a = 12 - 3d into equation 2 , equation 2 then becomes
12 - 3d + 7d = 36
12 + 4d = 36
subtract 12 from both sides
4d = 36 - 12
4d = 24
divide through by 4
d = 6
substitute d = 6 into equation 3 to find the value of a, we have
a = 12 - 3d
a = 12 - 3 ( 6)
a = 12 - 18
a = -6
Therefore , the 17th term of the sequence will be :
[tex]t_{17}[/tex] = a + 16d
[tex]t_{17}[/tex] = -6 + 16 (6)
[tex]t_{17}[/tex] = -6 + 96
[tex]t_{17}[/tex] = 90
Therefore : the 17th term of the sequence is 90

Range: (−∞, 0)
Domain: (−∞, 0)∪ (0, ∞)
Range: (0, ∞)
Domain: (−∞, ∞)
Range: (−∞, 0)
The domain and the range of the functions is real numbers. Hence, option A is correct.
We need to determine the domain and range of the function [tex]\bold{f(x)=-35x^3}[/tex].
Let us define the domain and the range of the function:
Domain:
When all the possible values of an independent variable for which we get the real value of a dependent variable then the values of the independent variables is called domain of the function.
Range:
All the possible values of the function is called the range of the function. Range is the sub-set of co-domain.
Now,
For the given function [tex]f(x)=-35x^3[/tex].
No value of x can restrict the above function hence its domain is real number that is [tex](-\infty, +\infty)[/tex].
And, range of the function is also the same [tex](-\infty, +\infty)[/tex].
Thus, the domain and the range of the functions is real numbers. Hence, option A is correct.

The domain and range of the cubic function f(x) = -35x^3 are both all real numbers, because there are no restrictions on x and the function's output covers all real values.
Explanation:The function described is f(x) = −35x^3. The domain of a polynomial function, which includes cubic functions like this one, is all real numbers because there are no restrictions on the values that x can take. Therefore, the domain is (−∞, ∞). Since the leading coefficient of the cubic term is negative, the ends of the graph will go towards negative infinity as x goes to positive and negative infinity. Therefore, the range of the function is also all real numbers, which we write as (−∞, ∞).

Julio sold candles for three weeks. Let x represent the number of candles he sold the first week. He sold twice the number of candles the second week as he did the first week. In the third week, Julio sold 4 less than the number he sold the first week. Which expression represents the total number of candles Julio sold in the three weeks?
The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.
Step-by-step explanation:
Let,
x be the number of candles sold by Julio in first week.
According to given statement;
Candles sold in first week = x
He sold twice the number of candles the second week as he did the first week.
Candles sold in second week = 2x
In the third week, Julio sold 4 less than the number he sold the first week.
Candles sold in third week = x-4
Total candles sold = First week + Second week + Third week
Total candles sold = x+2x+(x-4)
The expression x+2x+(x-4) represents the number of candles Julio sold in three weeks.

if f(x)=y then when x is 1 2(3)^X= 6
Answer:

Step-by-step explanation:
given: [tex]f(x) = 2(3)^{x}[/tex]
substitute some values for x and see which curves accurately reflect the corresponding y-values:
when x = 0, f(0) = 2(3)^0 = 2(1) = 2
hence the graph must pass through the point (0,2)
We can see from the choices that the 2nd and 4th graphs do not pass through (0,2), so we can eliminate these 2 from consideration
when x = 1, f(1) = 2(3)^1= 2(3) = 6
hence the graph must pass through the point (1,6)
We can see that the 3rd graph does not pass through this point so we can eliminate the 3rd graph also.
Only the 1st graph gives points consistent with the 2 cases above.
how do you estimate 175.32 ÷ 3 =
Answer:
≈ 58
Step-by-step explanation:
Estimation usually means you want an answer good to one or maybe two significant figures. That usually means you want to round the numbers involved to one or two significant figures.
Doing that here transforms the problem to 180/3 = 60, an answer with one significant figure.
You can improve the estimate a bit by recognizing that it is a little high (the numerator is higher than 175.32, but the denominator is the same). Since the numerator is high by about 5, the estimate is high by about 5/3 or a little less than 2. A closer estimate will be 60 - 2 = 58.
_____
The degree to which you refine the estimate will depend on the error requirements you have. Certainly an estimate of 60 is within 10% of the true value, so is "close enough" for many purposes.
To estimate 175.32 by 3, round 175.32 to 175, and divide by 3 to get 58. Since 175 is just under 180, which divides evenly by 3 to give 60, an estimate of 58 is reasonable.
To estimate the division of 175.32 by 3, we can round the numbers to make the calculation easier. First, we round 175.32 to 175 which is very close in value, and 3 remains as it is because it is already a whole number. So, our estimation becomes 175 / 3.
Dividing 175 by 3 gives us 58 as 3 times 58 is 174. We can see that this approximation is just 1 less than our rounded number, so it is a reasonable estimate. Therefore, 175.32 / 3 is approximately 58 when we estimate it without a calculator.
To check our estimation, we can compare it to similar, simple calculations. For example, if we divide 180 by 3, we get 60. Since 175 is slightly less than 180, our estimation of 58 is likely a good approximation for the division of 175.32 by 3.

The model builder has 4 pieces of balsa wood that are 4 cm, 5 cm, 6 cm, and 7 cm in length. How many different combinations of 3 pieces can be used to make triangles without breaking or cutting the pieces? List the combinations as inequalities.
Answer:
4<5<6
4<5<7
4<6<7
5<6<7
since there are 4 pieces of wood, you will have 4 combinations. since the sum of the 2 shortest sides need to be more than the longest side the inequalities above are valid.
Hope this helps!!
Final answer:
Out of the four lengths of wood provided, there are three valid combinations that can form triangles: 4 cm, 5 cm, 6 cm; 4 cm, 6 cm, 7 cm; and 5 cm, 6 cm, 7 cm. These combinations satisfy the Triangle Inequality Theorem, which is necessary for forming triangles.
Explanation:
To determine how many different combinations of 3 pieces of balsa wood can be used to make triangles, we must recall the Triangle Inequality Theorem which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the remaining side. For the pieces of lengths 4 cm, 5 cm, 6 cm, and 7 cm, we can form the following combinations that satisfy the Triangle Inequality Theorem:
4 cm, 5 cm, 6 cm
4 cm, 6 cm, 7 cm
5 cm, 6 cm, 7 cm
The inequalities for these combinations are as follows:
4 cm + 5 cm > 6 cm
4 cm + 6 cm > 5 cm
5 cm + 6 cm > 4 cm
4 cm + 7 cm > 6 cm
6 cm + 7 cm > 4 cm
5 cm + 7 cm > 6 cm
Each of these combinations is valid as the sum of the lengths of any two pieces is greater than the length of the third piece.

Cost of ticket= $22 per teacher and $11.5 per student.
Total amount paid= $113.
Lets assume number of teacher be "x" and number of students be "y".
Now, forming an equation for cost of each trip.
we know, total cost= [tex]cost\ of \ each\ ticket \times numbers\ of\ tickets[/tex]
∴Art museum trip, [tex]5.5x+3y= 29[/tex] ---- 1st equation
Science museum trip, [tex]22x+11.5y= 113[/tex] ---- 2nd equation
Next using elimination method to find number teacher and students
[tex]5.5x+3y= 29\\22x+11.5y= 113[/tex]
Multiplying both side of 1st equation by 4
∴ [tex]22x+12y= 116\\22x+11.5y= 113[/tex]
changing sign of 2nd equation on both side and solving it.
∴ [tex]0.5y= 3[/tex]
Dividing both side by 0.5
[tex]y= \frac{3}{0.5}= 6[/tex]
Hence, number of students on field trip was 6.
Subtituting the value of y in 1st equation to find the number of teachers in field trip.
[tex]5.5x+3y= 29[/tex]
⇒ [tex]5.5x+3\times 6= 29[/tex]
⇒ [tex]5.5x+18= 29[/tex]
Subtracting both side by 18
⇒ [tex]5.5x= 11[/tex]
Dividing both side by 5.5
⇒ [tex]x= \frac{11}{5.5}= 2[/tex]
Hence, there were 2 teachers on field trips.
A woman traveled 2445.9 miles in 18 hours five minutes what is the average speed of her flight in miles per hour
The average speed is 135.26 miles per hour
Solution:
Given that, woman traveled 2445.9 miles in 18 hours five minutes
To find: Average speed of her flight in miles per hour
Let us first convert 18 hours 5 minutes to hours
We know that,
[tex]1 \text{ minute } = \frac{1}{60} \text{ hour }[/tex]
Therefore,
[tex]5 \text{ minute } = \frac{5}{60} \text{ hour } = 0.083 \text{ hour }[/tex]
Thus we get,
18 hours five minutes = 18 hour + 0.083 hour = 18.083 hour
Given that, distance = 2445.9 miles
Average speed is given by formula:
[tex]Average\ speed = \frac{distance}{time}\\\\Average\ speed = \frac{2445.9}{18.083}\\\\Average\ speed = 135.26[/tex]
Thus average speed is 135.26 miles per hour
Which of the following are like terms in this expression? 12a-7+7a+12b
Answer:
Step-by-step explanation:
in order to be like terms, they have to have the same variable (and exponent, if there is any).....or be just a constant with no variables (just a number)
like terms in 12a - 7 + 7a + 12b are :
12a and 7a....because they have the exact same variable (a)
12b....no like terms
-7...no like terms
so ur answer is : 12a and 7a

18-6.3x = 49.5
Answer:
When solving equations you goal is to get x by itself so
18-6.3x=49.5 (first step would be to minus 18 from each side)
-6.3x=31.5 (18-18=0, 49.5-18=31.5) (now you want to divide each side by -6.3)
x=-5 (-6.3/-6.3=1, 31.5/-6.3=-5)
Your final answer is
x=-5
Hope this helps ;)

which scenario best matches the linear relationship expressed in the equation y=-14+1700
1) Kent has $1,700 in his bank account and spends $14 each week.
2) Kent has $1,700 in his bank account and deposits $14 each week.
3) Kent had $1,700 in his bank account and deposited another $14.
4) Kent has $14 in his bank account and spent $1,700.
Question:
Which scenario best matches the linear relationship expressed in the equation y = –14x + 1,700?
1) Kent has $1,700 in his bank account and spends $14 each week.
2) Kent has $1,700 in his bank account and deposits $14 each week.
3) Kent had $1,700 in his bank account and deposited another $14.
4) Kent has $14 in his bank account and spent $1,700.
Answer:
Option 1) Kent has $1,700 in his bank account and spends $14 each week.
Step-by-step explanation:
Let x denote the number of weeks.
Option 1: Kent has $1,700 in his bank account and -14x as the negative sign denotes how much amount he spend each week.
Thus, Option 1 is the correct answer.
Option 2: Kent has $1,700 in his bank account and deposits $14 each week.
Writing it as equation, we have, [tex]y=14x+1700[/tex] which is not the expressed linear equation.
Hence, Option 2 is not the correct answer.
Option 3: Kent had $1,700 in his bank account and deposited another $14.
Writing it as equation, we have, [tex]y=14+1700[/tex] which is not the expressed linear equation.
Hence, Option 3 is not the correct answer.
Option 4: Kent has $14 in his bank account and spent $1,700.
Writing it as equation, we have, [tex]y=14-1700[/tex] which is not the expressed linear equation.
Hence, Option 4 is not the correct answer.
Thus, the scenario that matches the linear equation relationship expressed in the equation is Option 1.
The answer is Kent has $1,700 in his bank account and spends $14 each week.
