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

Question

Amy has for gerbils Which Way 20 G 22 G 24 and 26 G what is the total weight of the gerbils in milligrams

Solution 1

First, I'll translate the problem into English:

Amy has four gerbils whose masses are 20 g, 22 g, 24 g, and 26 g.

What is the total mass of the gerbils in milligrams?

First add the masses in grams:

20 g + 22 g + 24 g + 26 g = 92 g

Now convert grams into milligrams.

1 gram = 1000 milligrams

92 g * 1000 = 92,000 mg

Answer: The total mass is 92,000 mg.

Question

How do i simplify 40 15Ã—40 2

Solution 1

I am going to assume that you meant 40(15 x 40)2,, but if not then please let me know and I will fix my answer for you.

The first step for solving this is to multiply the numbers in the parenthesis.

40 x 600 x 2

Now multiply the first two numbers together.

24000 x 2

Multiply the final two numbers together to get your answer.
