A. 10
B. 20
C. 40
D. 80

Answers

Answer 1

Answer:

C. 40

Step-by-step explanation:

Area of model x (scale factor)^2 = Area of enlarged

[tex]A(2)^{2} = 160\\ 4A = 160\\4A/4 = 160/4\\A = 40[/tex]

Does anyone know what number 7 is I’m very confused.

Answers

Answer: [tex]\huge\boxed{5 \text{ prices}}[/tex]

Step-by-step explanation:

Because the mean is simply the mathematical average of all the points, simply add all the prices and divide by the amount of prices, or 10.

100 + 150 + 80 + 240 + 130 + 170 + 210 + 165 + 275 + 90 = 1610, then divide by 10 to get 1610 / 10 = 161.

Because there is a absolute deviation of 50 from the mean, simply subtract and add fifty to learn that the least they will pay is $111, and the most they will pay is $211, and 5 prices fall within this range.

When can you use the square roots of perfect squares to determine the perfect roots of decimals ?

Answers

If you want to find the decimal value of a square root, you can use the 2 closest perfect squares to them.

Example

Approximate the value of sqrt20

Pick the 2 closest perfect squares, one before and one after 20:

16 and 25.

So, the square root of 20 has to be between 4 and 5.

Since 20 is closer to 16 than it is to 25,

We can estimate the decimal value of sqrt20 to be around 4.4

In one day, The Tool Shed rented out 25 self-propelled and riding mowers for a total fee of $900. The dolly rental cost was $20 for each self-propelled mower and $40 for each riding mower. Find the number of self-propelled mowers "(x)" and the number of riding mowers " (y)' rented for that day

Answers

They rented out 5 self-propelled mowers and 20 riding mowers.

Data;

Total number of tool rented out = 25Cost of tools rented = $900

System of Equations

To solve this problem, we have to write a system of equations to represent the problem.

since we have

x = self - propelled mowery = riding mowers

Let's write equations with these variables.

[tex]x+y = 25...equation (i)\\20x+40y = 900...equation(ii)[/tex]

From equation (i)

[tex]x+y= 25\\x = 25 - y...equation(iii)[/tex]

Put equation (iii) into equation (ii)

[tex]20x+40y=900\\x = 25-y\\20(25-y)+40y=900\\\\500-20y+40y=900\\500+20y=900\\20y=900-500\\20y=400\\\frac{20y}{20}=\frac{400}{20}\\ y=20[/tex]

Let's substitute the value of y into equation(i)

[tex]x+y =25\\x+20 = 25\\x = 25 - 20\\x = 5[/tex]

From the calculations above, they rented 5 self-propelled mowers and 20 riding mowers.

Answer:  705

=================================================

Explanation:

mu = population mean = 1300

sigma = population standard deviation = 20

Compute the z score based on x = 1330

z = (x-mu)/sigma

z = (1330-1300)/20

z = 30/20

z = 1.5

Asking to compute P(X < 1330) is the same as P(Z < 1.5) in this specific context when mu = 1300 and sigma = 20.

Use a Z table or a calculator to find that P(Z < 1.5) is roughly 0.93319

About 93.319% of the 755 bulbs are expected to last less than 1330 hours.

0.93319*755 = 704.55845

That value rounds to 705

Answer:

8 = m, No solution

Step-by-step explanation:

1. -88 = -3(4m + 5) - (1 - 3m)

-88 = -12m - 15 - 1 + 3m : distributed into parentheses

-88 = -9m - 16 : combined like terms

+16           + 16 : adding to cancel out

-72 = -9m

/-9       /-9 : dividing by -9 to cancel

8 = m

2. -4(5k - 7) + 2k = -2(9k + 5)

-20k + 28 + 2k = -18k - 10 : distributed into parentheses

-18k + 28 = -18k - 10 : combined like terms

       + 10            + 10 : adding to cancel out

-18k + 38 = -18k

+18k            +18k : adding to cancel out

38 = 0k (No solution)

Answers

Answer:

30a-18

it is as siplified as possible

Answer:

30a - 18

Step-by-step explanation:

What's the distributive property?

The distributive property is a property of math that helps with multiplication, usually in the form a(b + c). When using this property, a number, a, is distributed to the terms inside the parentheses, like b and c.

Given the information above, let's simplify 6(5a - 3).

[tex](6)(5a) + (6)(-3)[/tex] [tex]30a - 18[/tex]

Therefore, the answer is 30a - 18.
