Mixed Practice Test 3.3 Review: Why did the Teacher?

To find out how much change Craig would receive after shopping.

To find determine the greatest number of games that can be played

4.9375 rounds to 4

Craig does not have enough money for 5 games.

It changes the direction of the inequality and flips the relationship over zero on the number line.

The teacher likes the greater than sign more than the less than sign.

earns $125

earns an additional $5

c is the number of pieces of furniture Mrs. Kimbel sells

Because 11w and -6 do not get along

The teacher wanted to confuse the students by including multiple negative signs.

when multiplying two negative numbers, the negative signs cancel each other out, resulting in a positive product.

a + b = b + c

(a + b) + c = a + (b + c)

a + 0 = a

a(b + c) = ab + ac

3x - 8

-3x + -8

3x + 8

Since the diameter is half of the radius

Since the diameter is the radius squared

since the diameter is twice as long as the radius

since the diameter is the radius times pi

Surface area is the total area of all the faces of a three-dimensional object.

rectangular pyramid

rectangular prism

Adding the area is the last step when calculating the volume.

Adding the area of the faces is the last step when calculating the surface area.

Volume equals area of the base divided by the height.

Volume equals the boundary point times the height.

Volume equals base times height.

Volume equals area of the base times the height.

When finding the volume, calculate the area of one face, then multiply by 4.

I do not think the teacher knows why 4, 6, and 3 are multiplied.

The teacher saw the front face's dimensions are 3ft by 6ft and multiplied by 4 since that is the teacher's lucky number.

There are 4 sides of the prism that share the dimensions 3ft by 6ft.

The two bases of the prism share the dimensions 3ft by 3ft.

The three bases of the prism share the dimensions 3ft by 2ft.

The two bases of the prism share the dimensions 6ft by 2ft.

The three bases of the prism share the dimensions 6ft by 2ft.

The teacher was trying to spice things up by multiplying by a decimal.

To find how many feet wide Lot B is

To find the combined area of the property

To find the area of Lot A

To find the area of Lot B

To find the area of Lot B

To find the area of Lot A

To find the width of Lot B

To find the width of Lot A

Since the width of Lot A is 52, the width of Lot B is 52.

The number 52 represents the area of Lot A.

Since the length Lot A is 52, the length of Lot B is 52.

The number 52 represents the area of Lot B.

The formula to find the area of a rectangle is A = lw,

so

1,820w = 52.

To solve,

divide 1820 by 52.

The formula to find the area of a rectangle is A = lw,
