Question

Booker own 85 video games. He has 3 shelves to put the games on. Each shelf can hold 40 video games. How many more video games do he have room for

Solution 1

Booker has room for **35 more video games** since his 3 shelves (which can hold 40 games each) holds a total of 120. 120-85 = 35

Solution 2

35. Two shelves hold 80. And then the last five can go on the third. That means the third shelf can hold 35 more games

Question

Which of the following statements is true? If two polygons are similar, then the corresponding sides are proportional and the corresponding angles are proportional. If two polygons are similar, then the corresponding sides are proportional and the corresponding angles are congruent. If two polygons are similar, then the corresponding sides are congruent and the corresponding angles are proportional. None of the choices are correct.

Solution 1

If two **polygons **are similar, then the corresponding sides are **proportional **and the corresponding angles are congruent. Option B is correct.

In **congruent geometry**, the shapes that are so **identical**. can be superimposed to themselves.

A **polygon **is defined as a **geometric shape **that is composed of 3 or more sides these sides are equal in length, and an equal **measure **of angle at the vertex,

Examples of polygons, equilateral triangles, squares, pentagons, etc

Here,

Since if two polygons are similar it is only possible if their sides are proportional or equal and angles are also congruent or equal. So, all the options are incorrect except option B.

Thus, Â If two **polygons **are similar, then the **corresponding **sides are proportional and the corresponding angles are congruent. Option B is correct.

Question

What are the factors of m2 â€“ 6m + 6m â€“ 36? (m â€“ 2)(m + 18) (m â€“ 3)(m + 3) (m â€“ 4)(m + 9) (m â€“ 6)(m + 6)

Solution 1

**Answer:**

**Step-by-step explanation:**

we have

Simplify

we know that

In a difference of square

Remember that

therefore

Solution 2

(m â€“ 6)(m + 6) is the answer.

If you distribute them, you'll getÂ m^2 - 36

If you distribute them, you'll getÂ m^2 - 36

Question

Mr zucco baked a total of 270 cupcakes and muffins. After ue sold 1/3 of the cupcakes and baked 18 more miffins, he had twice as many cupcakes as muffins. How many cupcakes and muffins did mr. Zucco bake to begin with?

Solution 1

Let cupcakes = c and muffins = m.

c + m = 270

After 1/3 of cupcakes are sold (leaving 2c/3) and 18 more muffins are baked (m + 18), there are twice as many cupcakes as muffins:

2c/3 = 2(m + 18)

2c/3 = 2m + 36

c = 3m + 54

Substituting into the original equation:

3m + 54 + m = 270

4m = 216

m = 54 muffins

c = 3(54) + 54 = 216 cupcakes

c + m = 270

After 1/3 of cupcakes are sold (leaving 2c/3) and 18 more muffins are baked (m + 18), there are twice as many cupcakes as muffins:

2c/3 = 2(m + 18)

2c/3 = 2m + 36

c = 3m + 54

Substituting into the original equation:

3m + 54 + m = 270

4m = 216

m = 54 muffins

c = 3(54) + 54 = 216 cupcakes

Question

two lengths of stereo wire total 32.5 ft. one length is 2.9ft longer than the other. how long is each length of wire?

Solution 1

The length of the long one is half the total plus half the difference:

Â (1/2)(32.5 +2.9) ft = 17.7 ft

The length of the short one is 2.9 ft less:

Â 17.7 ft -2.9 ft = 14.8 ft.

_____

If you like, you can write an equation for the length of the long wire (L).

Â L +(L -2.9) = 32.5 . . . . . . . total length of both wires

Â 2L = 32.5 +2.9 . . . . . . . . . simplify, add 2.9

Â L = (1/2)(32.5 +2.9) . . . . . looks a lot like the solution above.

Â (1/2)(32.5 +2.9) ft = 17.7 ft

The length of the short one is 2.9 ft less:

Â 17.7 ft -2.9 ft = 14.8 ft.

_____

If you like, you can write an equation for the length of the long wire (L).

Â L +(L -2.9) = 32.5 . . . . . . . total length of both wires

Â 2L = 32.5 +2.9 . . . . . . . . . simplify, add 2.9

Â L = (1/2)(32.5 +2.9) . . . . . looks a lot like the solution above.
