A)The worker uses exactly 140 screws and 80 bolts to make 20 metal desks.

B)The worker uses exactly 80 screws and 140 bolts to make 20 metal desks.

C)The worker uses exactly 17 screws and 14 bolts to make 10 metal desks.

D)The worker uses exactly 14 screws and 17 bolts to make 10 metal desks.

Answer:

3/20 or 0.15 or 15%

Step-by-step explanation:

The experimental probability is

amount of wanted outcomes/total amount of outcomes

Less than 3 is 1 and 2.

1= 14 times

2= 16 times.

Add, get 30.

30 is the amount of wanted outcomes, and the total is 200.

30/200 is either 3/20, 0.15, or 15%, because of different formats.

Answer:

3.375 miles

Step-by-step explanation:

A runner runs at a rate of 4.5 miles per hour. How far does the runner run in 0.75 hours?

x = hours they ran

4.5x <== substitute 0.75 for x

4.5(0.75) <== multiply

3.375 miles

The volume of prism is,

⇒ V = 126 yards²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A right prism has a triangular base. The length of the base is 12 yards and the height of the base is 3 yards. The height of the prism is 3.5 yards.

We know that;

The volume of prism is,

⇒ V = B × H

Where,  B is the area of the base and h is the height of the prism.

Hence, We get;

The volume of prism is,

⇒ V = 12 × 3 × 3.5

⇒ V = 126 yards²

Thus, The volume of prism is,

⇒ V = 126 yards²

Answer:

Write the absolute value equations in the form

x−b

=c (where b is a number and c can be either number or an expression) that have the following solution sets.

Chapter Reference

a

Two solutions: x=2, x=14.

Step-by-step explanation:

The absolute value equations in the form |x-b|=c is 6.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that;

Two solutions are x=2 and x=14

Now,

To write an absolute value equation that has these solutions, we need to find a common value of b and c that satisfy the property above. One possible way to do this is to find the midpoint and the distance between the two solutions. The midpoint is the average of the two solutions, and the distance is half of their difference. The midpoint will be the value of b, and the distance will be the value of c.

Using this method, we get:

b = (2 + 14) / 2 = 8

c = (14 - 2) / 2 = 6

Therefore, by the given equation the answer will be 6

Answer:

The answer to number 4 would be 576cm^3

Step-by-step explanation:

Number 4:

The formula for volume would be V=B·h

to find B your going to find the base of the triangle which would be B=1/2·8·9 so B=36

Then you find the height which is 16 because it connects the two bases of the triangular prism

Next you multiply B·h so 36·16

Lastly, add your units and cube the number because you are foinding volume.

Answer:

A: 4

Step-by-step explanation:

So first you can move the 2^-5 to the denominator, making the equation (2^2) (4^3) / (2^5) (2)

Then simplify the terms so you end up with (4)(64) / (32) (2)

Then multiply the denominator so you end up with (4) (64) / (64)

Since both the denominator and numerator have 64, those cancel out leaving you with 4
