Question

a print shop printed and assembled 8 books in 5 minutes. At this rate how many books can be printed and assembled 3 hours?

Solution 1

288 books.

8 books in 5 minutes.

60 minutes in one hour.

5 * 12 = 60

60 minutes * 3 = 3 hours

8 * 12 = 96

96 books in one hour.

96 * 3 = 288

288 books in three hours.

8 books in 5 minutes.

60 minutes in one hour.

5 * 12 = 60

60 minutes * 3 = 3 hours

8 * 12 = 96

96 books in one hour.

96 * 3 = 288

288 books in three hours.

Solution 2

5 min * 12 = 60 min = 1 hr * 3 = 3Â hrs

8 * 12 = 96 * 3 = 288

288 Books can be assembled in 3 hrs

8 * 12 = 96 * 3 = 288

288 Books can be assembled in 3 hrs

Question

An architect designs a rectangular flower garden such that the width is exactlyâ€‹ two-thirds of the length. If 220 feet of antique picket fencing are to be used to enclose theâ€‹ garden, find the dimensions of the garden.

Solution 1

The perimeter of this square is 220, so:

2L + 2w = 220

w = 2/3 L

We can input the w:

2(2/3 L) + 2w = 220

10/3L = 220

10L = 660

L = 66

**The width is 44**

**The length is 66**

2L + 2w = 220

w = 2/3 L

We can input the w:

2(2/3 L) + 2w = 220

10/3L = 220

10L = 660

L = 66

Question

A chief had 6 cups of berries and will use 2/3 cup of berries for each serving of fruit salad. How many servings can be made ?

Solution 1

3.96 or 3 because it is not all the way 4 unless rounded

Solution 2

He would be able to make 4 servings out of it:

*6 * 2/3=4*

Question

a shipping company uses large crates to ship certain items. the volume of the crate is 72 cubic feet. What is the height , in feet, of the crate?

Solution 1

Volume = Length * Width * Height

72 = 6 * 3 * height

72 = 18h

4=h

**The height of the crate is 4 feet.**

72 = 6 * 3 * height

72 = 18h

4=h

Solution 2

6 * 3 * h = 72

18 * h =Â 72

Â /18 Â Â Â /18

h = 4

the height of the crate is 4 ft

18 * h =Â 72

Â /18 Â Â Â /18

h = 4

the height of the crate is 4 ft

Â is 1/1000

Â is 1/1000

Question

This system has one solution. {y=âˆ’2x+4y
{=x2+4x+13
What is the y-coordinate of the solution?
Enter your answer in the box. y =[]

Solution 1

**Answer:**

**The y-coordinate of the solution is, 10**

**Step-by-step explanation:**

**Given the system of equation:**

Â Â Â Â Â Â ....[1]

Â Â Â Â ....[2]

**Equate the equation [1] and [2] we have;**

**Add 2x to both sides of an equation:**

**Subtract 4 from both sides we have;**

or

**Using perfect square:**

â‡’We can write the equation as:

then;

â‡’

Subtract 3 from both sides we have;

x = -3

**Substitute value of x in [1] we have;**

â‡’

Solution for the given system of equation = (-3, 10)

**Therefore, the Â y-coordinate of the solution is, 10**
