Answer:

The circumference talks about the outside of the circle. So the formula for the circumference of a circle is 2πr (r stands for radius and π is pi. In this case we use 3.14 for pi).

Since the radius is half of the diameter and we know that the diameter of the trashball is 4 in, we half the 4. So the radius of the trashball is 2 in.

Now plug everything in the formula.

2(3.14)(2) = 12.56.

The circumference of the trashball is 12.56 in.

Answer: (1, 2)

which means

x = 1

y = 2

Step-by-step explanation:

y = -x + 3

y = 2x

Because both equations are set equal to y, they can be set equal to each other. The equations are ready to go to use Substitution method.

Substitute.

-x + 3 = 2x

Add x to both sides.

3 = 3x

Divide by 3.

3/3 = x

1 = x

We can put the 1 in for x in either equation.

y = 2x

y = 2(1)

y = 2

Putting x for 1 into the other equation is a good check.

y = -x + 3

y = -1 + 3

y = 2

So the x and y that work in both of these equations is:

x = 1 and y = 2

The form that was asked for was ( , ).

So the answer is

(1, 2).

Answer: 1, 2

Answer: 81 ft^2

Hello! The surface area of the rectangular prism will follow this process:

Right triangle area: (1/2)bh

So that 6ft (4.5ft) = 27ft^2/2; though when one multiplies that by 2 (as there are two right triangles), we get a surface area of 27ft^2.

For the rectangle's area, it's slightly more deviated since each face is different in length: bh

Face 1 = 3ft(7.5ft) = 22.5ft^2

Face 2 = 3ft(6ft) = 18ft^2

Face 3 = 4.5ft(3ft) = 13.5 ft^2

Thus, if we add these all together (27ft^2. + 22.5ft^2 + 18ft^2 + 13.5 ft^2), we get 81 ft^2

Answer:

Marissa did not change the direction of the inequality sign.

Step-by-step explanation:

Hello!

We can solve the inequality as well, and compare our steps to Marissa's to verify her steps.

We have the same number, but a different inequality sign. This is because we have to flip the inequality sign when multiplying and dividing by a negative number.

Therefore, the answer is the last option, Marissa has to flip the inequality sign when multiplying by a negative number.

Answer:

All properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse 3. multiplicative identity

What is commutative property of addition?

The commutative property states that an expression of the form (A + B) can be solved as (B + A) by an addition operation that does not change the end result.

The commutative property of addition says that it doesn't matter how we add two numbers, the result of the addition would be same.

For two numbers x and y, we have: x + y = y + x

Thus, if we take 3 numbers as a,b and c;

a + b + c = b + a + c = b + c + a = a + c + b = c + a + b = c + b + a

We have been given an expression;

2/7 • 53 • 7/2

53 • 2/7 • 7/2

53 • 1

53

Then all properties that were used to simplify the following problem:

1. commutative property of multiplication

2. multiplicative inverse

3. multiplicative identity

Answer: per acre there is 7 pounds of seed per acre  

Step-by-step explanation:

you do 28 divided by 4 to get the pound of seeds per acre giving you 7

Answer:

[tex]\frac{1}{7}[/tex] acres

Step-by-step explanation:

[tex]\frac{1}{28}= \frac{y}{4}[/tex]

28 × y = 1 × 4

28y = 4

28y ÷ 28 = 4 ÷ 28

[tex]y=\frac{1}{7}[/tex]
