Answer:
1.75 %
Step-by-step explanation:
The formula for the future value (FV) of an investment is
FV =PV(1 + r/n)^nt
If the interest is calculated once a year, n = 1, and the formula reduces to
FV = PV(1 +r)^t
5550 = 5000(1 + r)⁶ Divide both sides by 5000
1.110 = (1+r)^6 Take the sixth root of each side
1 + r = 1.0175 Subtract 1 from each side
r = 0.0175 Convert to percent
r = 1.75 %
The interest rate is 1.75 %.
Given the numbers x = a and y = –b, which statement is true? A. –|x| = a and –|y| = b B. |–x| = –a and |–y| = b C. |x| = –a and –|y| = –b D. |x| = a and |y| = b
Answer:
D) |x| = a and |y| = b
Step-by-step explanation:
Given the numbers x = a and y = –b
Absolute function always gives the output as a positive number
Absolute function of |-x|= x
For example |5|= 5 and |-5| = 5
Given x=a
|x| = |a| = a, so |x| = a
Given y=-b
|y| = |-b| = b , so |y| = b
Hence, |x| = a and |y| = b

In the diagram below which distance represents the distance from point d to ab
Answer:CD
Step-by-step explanation:
There is a line from A-B and the fastest way to get there is to go "down" c
Answer: The answer is (A) CD.
Step-by-step explanation: We are given to choose the correct option that represents the distance from point D to AB.
We know that the distance between a point and a line is the length of the perpendicular drawn from the point to the line.
So, here CD will be the required distance from point D to AB, because CD is perpendicular from point D to AB.
Thus, (A) is the correct option.
50% of one-twentieth of the product of 12 and 5z + 5.
Final answer:
To simplify 50% of one-twentieth of the product of 12 and 5z plus 5, you first calculate the product (60z), take one-twentieth (3z), find 50% of that (1.5z), and then add 5 to get the simplified expression 1.5z + 5.
Explanation:
The question asks to simplify the expression 50% of one-twentieth of the product of 12 and 5z plus 5. Here are the steps to simplify this expression:
Firstly, calculate the product of 12 and 5z, which is 60z.
Then, find one-twentieth of this product, which is 60z / 20 = 3z.
50% of 3z is 1.5z.
Finally, add 5 to 1.5z, which gives you 1.5z + 5 as the simplified expression.
So, the simplified expression is 1.5z + 5.
50% of one-twentieth of the product of (12) and[tex]\(5z + 5\) is \( \frac{3z}{2} + \frac{3}{2} \).[/tex]
To calculate 50% of one-twentieth of the product of [tex]\(12\) and \(5z + 5\)[/tex], we'll follow these steps:
Step 1: Calculate the product of [tex]\(12\) and \(5z + 5\)[/tex].
[tex]\[ \text{Product} = 12 \times (5z + 5) \][/tex]
Step 2: Calculate one-twentieth of the product.
[tex]\[ \text{One-twentieth of the product} = \frac{\text{Product}}{20} \][/tex]
Step 3: Calculate 50% (or half) of one-twentieth of the product.
[tex]{50% of one-twentieth of the product}[/tex] = [tex]\frac{1}{2} \times \frac{\text{Product}}{20} \][/tex]
Now, let's perform the calculations step by step:
Step 1: Calculate the product of [tex]\(12\) and \(5z + 5\):[/tex]
[tex]\[ \text{Product} = 12 \times (5z + 5) \][/tex]
[tex]\[ = 12 \times 5z + 12 \times 5 \][/tex]
[tex]\[ = 60z + 60 \][/tex]
Step 2: Calculate one-twentieth of the product:
[tex]\[ \text{One-twentieth of the product} = \frac{60z + 60}{20} \][/tex]
[tex]\[ = \frac{60z}{20} + \frac{60}{20} \][/tex]
[tex]\[ = 3z + 3 \][/tex]
Step 3: Calculate 50% of one-twentieth of the product:
{50% of one-twentieth of the product} =[tex]\frac{1}{2} \times \left(3z + 3\right) \][/tex]
[tex]\[ = \frac{1}{2} \times 3z + \frac{1}{2} \times 3 \][/tex]
[tex]\[ = \frac{3z}{2} + \frac{3}{2} \][/tex]
So, 50% of one-twentieth of the product of (12) and[tex]\(5z + 5\) is \( \frac{3z}{2} + \frac{3}{2} \).[/tex]

how do you solve problem 33
Answer:
G(-1, 3)
Step-by-step explanation:
You need to try each point in the given equation to see which one does not work.
The definition of the function is that it has two different expressions. The upper expression is used for values of x that are less than or equal to -1.
For values of x less than or equal to -1, the expression is f(x) = 2x + 3.
Look at point F. Its x-coordinate is -1.5. Since -1.5 is less than or equal to -1, use the upper expression. Plug in -1.5 for x and find f(-1.5).
f(x) = 2x + 3
f(-1.5) = 2(-1.5) + 3 = -3 + 3 = 0
That gives point (-1.5, 0), so point F is on the graph of f(x).
Now let's look at point G(-1, 3). For point G, x is -1. Since -1 is also less than or equal to -1, you still use the upper expression for x = -1.
f(x) = 2x + 3
f(-1) = 2(-1) + 3 = -2 + 3 = 1
The point that contains x-coordinate -1 is point (-1, 1). Point G is (-1, 3), so point G is not on the graph of function f.
You already know the answer is point G, but let's continue to show how the other two points are part of the graph of the function.
Point H is (0, 4). For this point, the x-coordinate is 0. The lower expression is used for x greater than -1, and 0 is greater than -1, so you must use the second expression. Now we evaluate the function at x = 0 using the second expression.
f(x) = 4 + x
f(0) = 4 + 0 = 4
giving us point (0, 4).
Point H is (0, 4), so point H is on the graph of the function.
Now we do point J(4, 8). Like for point H, the x-coordinate of point H is greater than -1, so you use the second expression.
f(x) = 4 + x
f(4) = 4 + 4 = 8
giving point (4, 8).
Point J is (4, 8), so it is on the graph.
The only point not on the graph is point G.

In a flower garden, there are 6 tulips for every 9 daisies. If there are 30 tulips, how many daisies are there?
A.
51
B.
43
C.
45
D.
47
Answer: C. 45
Step-by-step explanation:
1. You know that there are 6 tulips for every 9 daisies. Then, if there are 30 tulips, you can write the following expresion, where [tex]x[/tex] is the number of daisies when there are 30 tulips:
[tex]\frac{6}{9}=\frac{30}{x}[/tex]
2. Then, you must solve for x as following:
[tex]6x=30*9\\6x=270\\x=\frac{270}{6}\\x=45[/tex]
3. Therefore, the answer is 45 daisies.
By creating and solving a ratio based on the given relationship of 6 tulips to 9 daisies, it is determined that if there are 30 tulips, there must be 45 daisies in the flower garden. Thus, the correct choice to the student's question is option C) 45 daisies.
To solve this problem, we can set up a ratio based on the information given: there are 6 tulips for every 9 daisies. The ratio of tulips to daisies is therefore 6:9. If there are 30 tulips, this ratio must be multiplied by a certain factor to reach 30. To find this factor, we divide 30 (the actual number of tulips) by 6 (the number of tulips in the ratio), giving us a factor of 5. We then multiply the daisy part of the ratio (9) by 5 to find the actual number of daisies.
6 tulips : 9 daisies = 30 tulips : x daisies
30 / 6 = 5
9 daisies * 5 = 45 daisies
Therefore, if there are 30 tulips in the garden, there are 45 daisies, which corresponds to choice C.

Please help answer these questions. My teacher said they were really easy but I just don't understand. Will mark brainliest !!!
Answer:
1. A = 59
2. A = 43
Step-by-step explanation:
If we have a right triangle we can use sin, cos and tan.
sin = opp/ hypotenuse
cos= adjacent/ hypotenuse
tan = opposite/ adjacent
For the first problem, we know the opposite and adjacent sides to angle A
tan A = opposite/ adjacent
tan A = 8.8 / 5.2
Take the inverse of each side
tan ^-1 tan A = tan ^-1 (8.8/5.2)
A = 59.42077313
To the nearest degree
A = 59 degrees
For the second problem, we know the adjacent side and the hypotenuse to angle A
cos A = adjacent/hypotenuse
cos A = 15.3/21
Take the inverse of each side
cos ^-1 cos A = cos ^-1 (15.3/21)
A = 43.23323481
To the nearest degree
A = 43 degrees
Irene makes 4 2/3 cups of pancake batter . she splits the
batter into 2 bowls . she mixes blueberries into 2 1/4 cups of batter and walnuts into the rest of the batter
1 . Estimate how much of the batter has walnuts in it .explain your estimate.
2 . find the actual amount of batter that has walnuts in it . explain how you your answer is reasonable .
Answer:
Step-by-step explanation:
An estimate is usually a guess, but I somehow think that's not what you want.
She starts with 4 2/3 cups of batter. When she divides it into two, one of the batters has 2 1/4 cups. That's the one she puts blueberries in.
The other batter is the one you are interested in. How big is it?
Estimate: One
The estimated size would be 4 2/3 - 2 1/3 = 2 1/3 which is an estimate. It is just taking the closest number to use so you don't have to grab your calculator.
Actual Size: Two
4 2/3 - 2 1/4 is the size of the second batter. Since 2/3 is greater than 1/4 you need only subtract the whole numbers and then the fractions.
Whole number subtraction: 4 - 2 = 2
Fraction subtraction: 2/3 - 1/4
Find the Lowest common multiple between 3 and 4: It is 12. 3 and 4 are prime to each other. They have nothing in common.

Amelia and Brianna work at a furniture store. Amelia is paid $240 per week plus 6% of her total sales in dollars, xx, which can be represented by g(x)=240+0.06xg(x)=240+0.06x. Brianna is paid $130 per week plus 8.5% of her total sales in dollars, xx, which can be represented by f(x)=130+0.085xf(x)=130+0.085x. Determine the value of xx, in dollars, that will make their weekly pay the same.
Answer:
x = $4400
Step-by-step explanation:
If we want their pay to be the same, the equations have to be equal
g(x)=240+0.06x = f(x)=130+0.085x
240 + .06x = 130+0.085x
Subtract .06x from each side.
240 + .06x - .06x = 130+0.085x-.06x
240 = 130 +.025x
Subtract 130 from each side
240-130 = 130-130 +.025x
110 = .025x
Divide each side by .025 to isolate x
110/.025 = .025x/.025
4400 =x
find the value of x in the figure below Assume that the lines are parallel
The value of x is 30.
We are given that lines l and m are parallel. We are asked to find the value of x.
Since we are given that l and m are parallel, we can use the property of alternate exterior angles.
This property states that when two lines are cut by a transversal, the alternate exterior angles are congruent.
In the diagram, we see that ∠A and 2x+15 ∘ are alternate exterior angles. Therefore, we have:
∠A=2x+15 ∘
We are also given that ∠A=75 ∘ .
Substituting this value into the equation above, we get:
75 ∘ =2x+15 ∘
Solving for x, we get:
2x=75 −15 ∘
2x=60 ∘
x= 60/2 ∘
x=30∘
Therefore, the value of x is 30 ∘ .

Answer:
Change "3" to "4"Change "46" to "128"Step-by-step explanation:
The table tells you that for every 1 package, you have 16 tortillas. Thus, the function is y = 16x.
y = amount of tortillas and x = number of packages
To find the number of packages for 64 tortillas, divide 64 by 16-- which gives you 4. Instead of "3" packages, change that number to "4".
To find the amount of tortillas in 8 packages, multiply 8 by 16-- which gives you 128 tortillas. Instead of "46", replace that amount with 128.
Divide 144 tortillas by 16, which gives you 9. The answer you gave is correct.
Multiply 10 packages by 16, which gives you 160-- your answer is also correct here.

B. {(3,22), (2,3), (8,27)}
C. {(4,29), (–6,–58), (7,19)}
D. {(–2,–18), (4,37), (5,15)}
And all of the points in the set must satisfy y ≤ 8x – 3.

Final answer:
After evaluating each set of points for the inequality y ≤ 8x – 3, it is found that set C satisfies the inequality for all its points, making it the correct set of points containing the solutions to the inequality.
Explanation:
The student's question is related to solving a linear inequality, specifically finding which set of points satisfies the inequality y ≤ 8x – 3.
To find the correct set of points that contain the solutions to this inequality, we must check each pair of (x, y) coordinates provided in the options. A coordinate pair is a solution to the inequality if substituting the x and y value into the inequality makes it a true statement.
For (-3, -17): -17 ≤ 8*(-3) – 3, which simplifies to -17 ≤ -24 – 3. Since -17 is not less than or equal to -27, this pair is not a solution.For (4, 11): 11 ≤ 8×4 – 3, which simplifies to 11 ≤ 32 – 3. Since 11 ≤ 29, this pair is a solution.For (7, 19): 19 ≤ 8×7 – 3, which simplifies to 19 ≤ 56 – 3. Since 19 ≤ 53, this pair is a solution.B. {(3,22), (2,3), (8,27)}
C. {(4,29), (–6,–58), (7,19)}
D. {(–2,–18), (4,37), (5,15)}
After checking each set, we can conclude that set C contains all the solutions to the inequality y ≤ 8x – 3.

Answer:
156.86
Step-by-step explanation:
We start by dividing 136.40 by 100 so we can figure how much 1 percent,(1.364) once we have that we multiply by 15 (20.46), we add that to the total
Answer:
Total bill including the tip = $156.86 .
Step-by-step explanation:
Given:Bill at a restaurant came to $136.40 the patrons decide to leave a 15% tip .
To find: What is the total bill including the tip.
Solution: we have given that
A restaurant bill came = $136.40 .
Tip percentage = 15% of bill
Tip cost = 15% of $136.40 .
Tip cost = $20.46 .
So, total bill including the tip = $136.40 + tip cost
= $136.40 + $20.46
= $156.86 .
Therefore , Total bill including the tip = $156.86 .
You work for a landscaper that has a customer needing to seed an area of land 80 feet by 40 feet in size. The garden center has 5-pound bags of grass seed. Each bag of seed can cover 25 square yards of land. You calculate that the area you need to seed is 3200 square feet. You divide by 25 to find that you need 128 bags to seed the area. Is this correct?
Answer:
No, the solution discussed in question is not correct.
Step-by-step explanation:
Length of the garden ,l= 80 feet
Breadth of the garden ,b= 40 feet
Area of the rectangle = l × b
Area of the garden = A
[tex]A=l\times b = 80 ft\times 40 ft = 3,200 ft^2[/tex]
Area covered by 1 bag of seeds of grass = [tex]25 yard^2=225 ft^2[/tex]
[tex]1 yard^2 = 9 ft^2[/tex]
Bags of seed of grass covering area of [tex]3,200 ft^2[/tex]:
[tex]\frac{3200 ft^2}{225 ft^2}=14.22[/tex]
14.22 bags of seed of grass will occupy the area covered by the garden.
What is the quotient of
y-5\sqrt{2y^2-7y-15}
A. 2y + 3
B. 2y − 3
C. 2y − 17y R −70
D. 2y − 17y R 70
Answer:
None of these
Step-by-step explanation:
y-5\√(2y2 - 7y -15)
On simplifying 2y2 - 7y -15, we get
2y2 – (10-3)y -15
= 2y2 – 10y -3y-15
= 2y(y-5)-3(y-5)
= (2y-3)(y-5)
On squaring nominator and denominator we get
(y-5)2/(2y-3)(y-5)
= (y-5)/(2y-3)
So the quotient becomes, 5/2
While the remainder becomes 2.5

Step-by-step explanation:
If 9 is added to twice a number and this sum is multiplied by 6, the result is the same as if the number is multiplied by 7 and 14 is added to the product. What is the number?
Answer:
The number is -1.
Step-by-step explanation:
Let the number be represented by n.
Then "9 is added to twice a number and this sum is multiplied by 6" is represented by 2n + 9, and
" the number is multiplied by 7 and 14 is added to the product" is
7n + 14.
Then the complete equation is 2n + 9 = 7n + 14.
We must solve this for n. To accomplish this, subtract 2n from both sides, obtaining 9 = 5n + 14. Then subtract 14 from both sides, obtaining
-5 = 5n. Then n must be -1.
Answer:
The number is -8

The ratios 8/7 and 9/7 are not equivalent. Using cross multiplication, we find that the cross products are different, signaling that these two ratios are not equivalent.
Explanation:To determine whether the ratios 8/7 and 9/7 are equivalent, we can cross multiply. In this case, if the two products are equal then the ratios would be equivalent.
Cross multiplication is a method used to test if two ratios are equivalent. It involves multiplying the numerator of the first fraction by the denominator of the second fraction and comparing that product with the product of the denominator of the first fraction and the numerator of the second fraction. If the two products are equal, then the two fractions are equivalent.
Using this method, the cross products of the ratios 8/7 and 9/7 are (8 * 7) and (9 * 7), which are 56 and 63, respectively. Since these two products are not equal, the two ratios are not equivalent.
