Question

What is the gcf of 12 78 and 90

Solution 1

The greatest common factor of 12, 78, and 90 is 6.

Factors are the numbers, that when multiplied with another number, equal the product.

Factors of 12: 1, 2, 3, 4, 6, and 12.

Factors of 78: 1, 2, 3, 6, 13, 26, 39, and 78.

Factors of 90: 1, 2, 3, 5, 6, 9, 10, 15, 18, 20, 45, and 90.

The Greatest Common Factor is the highest factor shared among the products. Thus proving 6 is the GCF.

I hope this helps!

Question

The front wall of your shed is in the shape of a trapezoid. The bottom measures 22 feet, the top measures 20 feet, and the height is 10 feet. Calculate the area of the front wall of your shed.

Solution 1

The area of a trapezoid is given by the formula:

A = (1/2)×(b₁ +b₂)×h

Substitute the given information and evaluate.

A = (1/2)×(22 ft +20 ft)×(10 ft)

A = (1/2)×(42 ft)×(10 ft)

A = (21 ft)×(10 ft)

A = 210 ft²

The area of the front wall of your shed is 210 ft².

A = (1/2)×(b₁ +b₂)×h

Substitute the given information and evaluate.

A = (1/2)×(22 ft +20 ft)×(10 ft)

A = (1/2)×(42 ft)×(10 ft)

A = (21 ft)×(10 ft)

A = 210 ft²

The area of the front wall of your shed is 210 ft².

Question

A ball is thrown into the air with an upward velocity of 32 ft/s. Its height h in feet after t seconds is given by the function h = –16t2 + 32t + 6. a. In how many seconds does the ball reach its maximum height? Round to the nearest hundredth if necessary. b. What is the ball’s maximum height? 1 s; 54 ft 2 s; 6 ft 2 s; 22 ft 1 s; 22 ft

Solution 1

For this case we have the following equation:

h = -16t2 + 32t + 6

Deriving we have:

h '= -32t + 32

Equaling to zero:

-32t + 32 = 0

We clear the time:

t = 32/32

t = 1 s

We are now looking for the maximum height:

h (1) = -16 * (1) ^ 2 + 32 * (1) + 6

h (1) = 22 feet

**Answer:**

**The ball reaches its maximum height in:**

**t = 1 s**

**The ball's maximum height is:**

**h (1) = 22 feet**

**option: 22 ft, 1 s**

h = -16t2 + 32t + 6

Deriving we have:

h '= -32t + 32

Equaling to zero:

-32t + 32 = 0

We clear the time:

t = 32/32

t = 1 s

We are now looking for the maximum height:

h (1) = -16 * (1) ^ 2 + 32 * (1) + 6

h (1) = 22 feet

Solution 2

**Answer: 22 ft, 1 s**

**Step-by-step explanation:**

Question

Amy paid $65.78 for a pair of running shoes during a 40%-off sale. What was the regular price?

Solution 1

This problem can be represented by the following:

sale price = (percentage off) * original price

Plug in the values given by the problem. 60% is represented in this equation as 0.6.

65.78 = 0.6x

Divide both sides by 0.6.

109.63 = x

The original price was**$109.63.**

sale price = (percentage off) * original price

Plug in the values given by the problem. 60% is represented in this equation as 0.6.

65.78 = 0.6x

Divide both sides by 0.6.

109.63 = x

The original price was

Question

a plane takes off at an angle of elevation of 15 degrees and travels in a straight line for 3,000 meters. What is the height of the plane above the ground at this instant?

Solution 1

SOH CAH TOA tells you the sine function of an angle gives the ratio of opposite side to the hypotenuse of the right triangle.

Sin = Opposite/Hypotenuse

In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

sin(30°) = height/(3000 m)

Multiplying by 3000 m, we get

height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...

1500 m

Sin = Opposite/Hypotenuse

In this problem, the angle is 15°, the hypotenuse is 3000 m and we want to find the length of the opposite side (the height above the ground).

sin(30°) = height/(3000 m)

Multiplying by 3000 m, we get

height = (3000 m)*sin(30°) = 1500 m

The height of the plane at that instant is ...

1500 m

Question

A pizza that was ordered for a party was already cut into 6 slices. If each serving of pizza was 1 3 of a slice, how many servings of pizza were available? A) 18 Eliminate B) 2 C) 1 18 D) 1 2

Solution 1

Hello!

I serving size was 1/3 of a slice

1/3 * 3 = 1

3 serving sizes made one slice

Multiply this by the amount of slices

3 * 6 = 18

There are 18 serving sizes

The answer is 18

Hope this helps!

Question

A group of students recycled 7 2/3 pounds of glass and 9 3/4 pounds of paper. How many pounds of glass and paper did the students recycle alltogether?

Solution 1

The students recycle 17 5/12 **pounds **of **glass **and **paper **all together.

**Fractions **represent the parts of a whole or collection of objects.

A **fraction **has two parts. The number on the top of the line is called the **numerator **and the number on the top of the line is called the **denominator**.

Now it is **given **that,

Pounds of **glass **recycled = 7 2/3

⇒ Pounds of **glass **recycled = 23/3

Pounds of **paper **recycled = 9 3/4

⇒ Pounds of **paper **recycled = 39/4

Thus, **total **pounds of **glass **and **paper **recycled = Pounds of **glass **recycled + Pounds of **paper **recycled

⇒ **total **pounds of **glass **and **paper **recycled = 23/3 + 39/4

⇒ **total **pounds of **glass **and **paper **recycled = 209/12

⇒ **total **pounds of **glass **and **paper **recycled = 17 5/12 pounds

Thus, the students recycle 17 5/12 **pounds **of **glass **and **paper **all together.

Question

If total liabilities are 1,000 and total assets are 8000 owner's e q u i t y must be

Solution 1

Total equity is equal to assets - liabilities.

Therefore,

8000 - 1000 = 7000

The owner's equity is**$7,000.**

Therefore,

8000 - 1000 = 7000

The owner's equity is
