Question

A video game was $38. This weekend the game will be marked 13 percent off. How much is the game this weekend?

Solution 1

Discount = 13% x $38 = 0.13 x 38 = $4.94

Cost of the game after discount = $38 - $4.94 = $33.06

**Answer:Â Â $33.06**

Cost of the game after discount = $38 - $4.94 = $33.06

Question

(she will have 1 inch left)

(she will have 1 inch left)

Question

How many cubic feet of water can a 18 inch by 19 inch by 36 inch aquarium hold?

Solution 1

Volume = Length x Width x HeightÂ

Volume = 18 x 19 x 36 = 12312 inÂ³

**Answer:Â Â 12312 inÂ³**

Volume = 18 x 19 x 36 = 12312 inÂ³

Solution 2

ft.

Question

Find the volume of a right prism with height h=10 cm, if the base is a trapezoid with height htr = 3 cm and bases of 2 cm and 5cm

Solution 1

We have been given that the base of the prism is a trapezoid. Hence, first of all we find the area of the trapezoid.

Trapezoid has height 3 cm and bases of 2 cm and 5 cm.

Hence, the area of the trapezoid is given by

Therefore, the volume of the right prism with height h=10 cm is given by

**Therefore, the volume of the right prism is 105 cubic centimeters.**

Solution 2

Area of the base = 1/2 x 3 xÂ ( 2 + 5 ) = 10.5 cmÂ²

Volume =10.5 x 10Â = 105 cmÂ³

**Answer:Â Â 105 cmÂ³**

Volume =10.5 x 10Â = 105 cmÂ³

Question

One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Solution 1

$5.53 dollars for 3.5lb. of grapes.

Question

There are 12 boys and 16 girls in a classroom. Which represents the simplified ratio of girls to students in the classroom?

Solution 1

3:7 is the simplest for girls to students in the classroom.

Solution 2

12/16= 3/4 you divide the numerator and denominator by 4 since that the greatest common factor

Question

Find the volume of a right prism with height h=10 cm, if the base is an equilateral triangle with side 4 cm, base altitude of â‰ˆ 3.5 cm.

Solution 1

Volume = Area of the base x Height

Area of the triangularÂ Â base = 1/2 x 3.5 x 4 = 7 cm

Volume = 7 x 10 = 70 cmÂ³

**Answer: 70 cmÂ³**

Area of the triangularÂ Â base = 1/2 x 3.5 x 4 = 7 cm

Volume = 7 x 10 = 70 cmÂ³

Question

Which gives 1600 m in km? (A) 16,000 (B)1600 (C)16 (D)1.6 (ALL ARE KM!)

Solution 1

1600m = 1600 Ã· 1000 = 1.6 km

**Answer: 1.6 km**

Question

Only 6 of the 75 trees in a park are at least 30 feet tall. What percent of the trees are under 30 feet tall?

Solution 1

Percentage of tress under 30 = 6/75 x 100 = 8%

**Answer: 8%**

Solution 2

**Answer:**

8%

**Step-by-step explanation:**

Question

How would you find the number, 3/7 of which is equal to t? (let's say it was any number, just need the equation)

Solution 1

Let the number be x

(3/7) x = t

I can't think of anything useful to add to this. How about an example?

Let x = 49

(3/7) x = t

(3/7) * 49 = t seven will go into 49

3 * 49 = t

t = 147Â

(3/7) x = t

I can't think of anything useful to add to this. How about an example?

Let x = 49

(3/7) x = t

(3/7) * 49 = t seven will go into 49

3 * 49 = t

t = 147Â
