Which description can be written as the expression 6b+5?
a) the difference of six times a number and five
b) the sum of six times a number and five
c) quotient of six times a number and five
d) the product of six times a number and five
Answer: b) the sum of six times a number and five
Step-by-step explanation:
The given expression is [tex]6b+5[/tex], where b represents any number.
The above expression has two terms combined by addition operation.
In the first term there is one variable b and 6 as coefficient of b and the second term is a constant term of 5.
Therefore, the correct description of the given expression [tex]6b+5[/tex] is " the sum of six times a number and five".
Option: b is the correct answer.
b) the sum of six times a number and five.
Step-by-step explanation:We are given an algebraic expression in term of a variable 'b' as:
6b+5
As we could see that here there are two terms in an expression one is: 6b and the other is 5 which is separated by a summation sign.
Hence, when 6 times of a number 'b' is added to 5 we get the given expression(i.e. 6b+5)
Hence, the answer is: Option: b

A fox, a coyote, and a wolf weigh a total of 120 pounds. The ratio of the weight of the fox to the weight of the coyote is 3:8. The weight of the coyote is 32 pounds. What is the weight of the wolf?
Answer:
the wolf is 76 lbs.
Step-by-step explanation:
first you have to divide 32 by 8, which is 4. Then you know that 4 is the divider to the simplified ratio, 3:8. So you multiply 3 and 4 which is 12. so you add 32 and 12 which is 44. then you subtract 44 by 120 which is 76. So The weight of the wolf is 76 lbs.
The marginal cost function of producing q mountain bikes is 600/0.3q+5.
If the fixed cost in producing the bicycles is 2200 , find the total cost to produce 30 bicycles.
If the bikes are sold for 205 each, what is the profit (or loss) on the first 30 bicycles?
Find the marginal profit on the 31st bicycle. ...?
The total cost to produce 30 bicycles is $5599.89. The profit from first 30 bikes is $550.11. The marginal profit on the 31st bike is $126.57.
Explanation:The marginal cost function given is 600/(0.3q+5). To find the total cost to produce 30 bicycles, we need to integrate the marginal cost from 0 to 30 and add the fixed cost of 2200.
The result of the integration is 2000*(ln|1+0.3q|). Calculating from 0 to 30 gives us 3599.89. Thus, the total cost to produce 30 bicycles considering the fixed cost is 5599.89.
The revenue of each bike sold is $205. So, the total revenue generated from selling 30 bikes is 30*$205 = $6150. The profit is then the difference between the revenue and the total cost, giving us $6150-$5599.89 = $550.11.
To find the marginal profit on the 31st bike, subtract the marginal cost at 31 bikes from the selling price. The marginal cost at 31 bikes is the marginal cost function evaluated at q=31, which is approximately $78.43, and hence, the marginal profit on the 31st bike is $205 - $78.43 = $126.57.

To find the total cost, multiply the quantity by the marginal cost function and add the fixed cost. To find the profit or loss, subtract the total cost from the revenue. The marginal profit can be found by subtracting the marginal cost from the selling price.
Explanation:To find the total cost to produce 30 bicycles, you need to calculate the variable cost and add it to the fixed cost. The variable cost can be found by multiplying the marginal cost function by the quantity of bikes. So, the variable cost is (600/0.3*30 + 5) = 6105. Adding the fixed cost of 2200 gives us a total cost of 8305.
To find the profit or loss on the first 30 bicycles, we need to subtract the total cost from the revenue, which is the selling price multiplied by the quantity. So, the revenue is 205 * 30 = 6150. The profit or loss is then 6150 - 8305 = -2155, indicating a loss of $2155.
The marginal profit on the 31st bicycle can be found by subtracting the marginal cost from the selling price. So, the marginal profit is 205 - (600/0.3*31 + 5) = -55, indicating a loss on the 31st bicycle.

Rectangle ABCD is reflected over the x-axis, followed by a reflection over the y-axis, and then rotated 180 degrees about the origin. What is the location of point A after the transformations are complete?
Rectangle ABCD is shown. A is at negative 5, 1. B is at negative 5, 3. C is at negative 1, 3. D is at negative 1, 1.
(−5, 1)
(5, −1)
(−5, −1)
(5, 1)
Answer:
First option is correct. The location of point A after the transformations is (-5,1).
Step-by-step explanation:
It is given that the coordinates of point A are (-5,1).
Rectangle ABCD is reflected over the x-axis. then x-coordinate remains the same but the sign of y-coordinate is changed.
[tex](x,y)\rightarrow (x,-y)[/tex]
Coordinates of point A are
[tex](-5,1)\rightarrow (-5,-1)[/tex]
After that ABCD is reflected over the y-axis, then y-coordinate remains the same but the sign of x-coordinate is changed.
[tex](x,y)\rightarrow (-x,y)[/tex]
Coordinates of point A are
[tex](-5,-1)\rightarrow (5,-1)[/tex]
After that ABCD rotated 180 degrees about the origin, then the sign of both coordinates are changed.
[tex](x,y)\rightarrow (-x,-y)[/tex]
[tex](5,-1)\rightarrow (-5,1)[/tex]
Therefore option 1 is correct.

A cylinder has a volume of 320 pi cu. in. and a height of 5". Find the radius of the cylinder. ...?
Answer:
radius of the cylinder is, 8 inches
Step-by-step explanation:
Volume of cylinder(V) is given by:
[tex]V = \pi r^2h[/tex] .....[1]
where,
r is the radius of the cylinder and
h is the height of the cylinder.
As per the statement:
A cylinder has a volume of 320 pi cu. in. and a height of 5"
⇒[tex]V = 320 \pi[/tex] cubic inches and h = 5 inches
Substitute these values in [1] we have
[tex]320 \pi = \pi r^2 \cdot 5[/tex]
Simplify:
[tex]320 = r^2 \cdot 5[/tex]
Divide both sides by 5 we have;
[tex]64=r^2[/tex]
or
[tex]r^2 = 64[/tex]
⇒[tex]r = \sqrt{64} = 8 in[/tex]
Therefore, the radius of the cylinder is, 8 inches
Final answer:
To find the radius of the cylinder, use the formula for the volume of a cylinder, V = πr²h. Rearrange the formula to solve for the radius, and solve the equation to find the value of r.So,radius of cylinder r=8inches.
Explanation:
To find the radius of the cylinder, we can use the formula for the volume of a cylinder, which is V = πr²h. In this case, we need to solve for the radius, so we rearrange the formula as follows:
320π = πr²(5)
We can cancel out the π's on both sides of the equation:
320 = r²(5)
Divide both sides of the equation by 5:
64 = r²
Take the square root of both sides to solve for r:
r = √64
r = 8
Therefore, the radius of the cylinder is 8 inches.

Mia is three years older than twice her sister Brooke's age. The sum of their ages is less than 30. What is the greatest age Brooke could be?
a.)7
b.)8
c.) 9
d.)10 ...?
The correct answer is b. 8. 8 is the greatest age Brooke could be.
Let's denote Brooke's age as B and Mia's age as M. According to the information given:
M = 2B + 3 (since Mia is three years older than twice Brooke's age).
We also know that the sum of their ages is less than 30:
M + B < 30.
Substituting the expression for M into the inequality, we get:
2B + 3 + B < 30,
3B + 3 < 30,
3B < 27,
B < 9.
Since Brooke's age must be a whole number, the greatest integer less than 9 is 8. Therefore, the greatest age Brooke could be is 8 years old.

A code is formed using four of these letters: A, B, I, K, N, O, and T. (Note that the order of the letters in the code matters; for example, ABIK is a different code from BAIK.) The size of the sample space is___ . The probability that the first three letters of the four-letter code are vowels is___ .
Answer:
[tex]7^4[/tex][tex]\dfrac{27}{343}[/tex]Step-by-step explanation:
we are given 7 alphabets out of which we need to choose 4 alphabets in order to make a code of 4 letters.Hence the size of the sample space is: [tex]7^4[/tex]
since we have to fill in 4 places with the help of these 7 letters.
so in first place we can select one out of any 7 letters, similarly for the second place as it is not mentioned that repetition is not allowed and the same can be done for third and fourth place.
Hence size of sample space is: [tex]7\times7\times7\times7=7^4[/tex]
Now the probability of an event is given by:Probability=(Number of favourable outcomes)/(Total number of outcomes)
Hence here the total number of outcomes=[tex]7^4[/tex]
Total number of favourable outcomes=outcomes that the first three letters are vowels=[tex]3\times3\times3\times7[/tex] (since in the first place we have three choices for a vowel{A,I,0} similarly for second and third place and in the fourth place any one of the 7 letters could come)
Hence the probability(P) that the first three letters of the four-letter code are vowels is given by:
[tex]P=\dfrac{3\times3\times3\times7}{7\times7\times7\times7}=\dfrac{3\times3\times3}{7\times7\times7}=\dfrac{27}{343}[/tex]
Hence, the Probability is: [tex]\dfrac{27}{343}[/tex]
