20

**Answer:**

John spends $23.60 at the barbershop.

**Step-by-step explanation:**

convert all % to decimals (/100)

0.2 x 25 = 5

25 - 5 = **$20**

0.18 x 20 = 3.6

20 + 3.6 = **$23.6**

What is 7x + 15 = 9x + 15 - 2x + 1 and how many solutions are there

**Answer:**

no solutions

**Step-by-step explanation:**

7x + 15 = 9x + 15 - 2x + 1

Combine like terms

7x+15 = 7x+16

Subtract 7x from each side

7x+15-7x = 7x+16-7x

15 =16

This is not a true statement so there are no solutions

maria's garden measures 14 feet by 16 feet and has a perimeter of 60 feet. Musharraf's garden measures 10 yards by 4 yards. What is the difference between the two perimeters?

The difference between the two perimeters is **32 yards**.

Maria's garden measures 14 feet by 16 feet and has a perimeter of 60 feet.

Musharraf's garden measures 10 yards by 4 yards. The perimeter will be:

= 2(10 + 4)

= 2 × 14

= 28 yards

The difference will be:

= 60 - 28

= **32 yards**.

Which would be the most suitable viewing window to solve the system below?

The **solution** of the **system** belongs to -1 ≤ x ≤ 1, -1 ≤ y ≤ 1.

Given a **system** of the **equations**:

x/3 + y/2 = 1/3 .... (1)

(5x)/6 - (3y)/4 = 1/6 ....(2)

**Multiply** 5/2 to equation (1) then **subtract** from equation (2), we get,

(5y)/4 + (15y)/8 = 5/6 - 1/6

(10y + 15y)/8 = 4/6

(25y)/8 = 4/6

25y = 4/6 x 8

y = 32/150

y = 0.21

To find the **value** of x,

x/3 + 32/300 = 1/3

x/3 = 1/3 - 32/300

x = 3(1/3 - 32/300)

x = 1 - 32/100

x = 0.68

From the given choices,

-1 ≤ x ≤ 1, -1 ≤ y ≤ 1.

a.

4 miles / hour

b. 9 miles / 1 hour

c. 18 miles /2 hours

d. 36 miles / 4 hours

**Answer: It would be b.**

A scale drawing of a house shows a closet with floor dimensions of 4.4 cm by 3.2cm. The scale from the drawing to the actual closet is 2cm for every 1m. WhT is the actual area of the closets floor

The actual area of the closet floor would be 3.52m

The actual **area** of the **closet** floor is 3.52m.

A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees.

It has different lengths and widths.

We have,

Closet dimensions:

**Length** = 4.4 cm

**Width** = 3.2 cm

We need to convert the unit cm into meters.

We are given that,

2cm = 1m

Multiply 4.4/2 on both sides

4.4 cm = 4.4/2 x 1m

4.4 cm = 2.2 m

Length = 2.2m

Multiply 3.2/2 on both sides.

3.2 cm = 3.2/2 x 1m

3.2 cm = 1.6 m

Width = 1.6m

The actual **area** of the **closet**:

= length x width

= 2.2m x 1.6m

= 3.52m

Thus the actual **area** of the **closet** floor is 3.52m.

Which equation is equivalent to the formula m = ca? a = cm a equals m over c c = am c equals a over m.

**Answer:**

**a = m/c**

**Step-by-step explanation:**

**I translated the paragraph into these options. Please check accuracy.**

m = ca?

a = cm No, a = m/c

**a = m/c ** **Yes**

c = am No, c = m/a

c = a/m No, c = m/a

The option b which is [tex]a=\dfrac{m}{c}[/tex] is correct answer.

Given to us:

[tex]m=ca[/tex]

**dividing **both sides by c, we get

a = 0

**Step-by-step explanation:**

The cube root (radical) is equivalent to x^(1/3). When that is divided by x^(1/3), the result is ...

(x^(1/3))/(x^(1/3)) = x^(1/3 -1/3) = x^0

Comparing that to x^a, we find **a=0**.

(a) The perimeter of a rectangular parking lot is 288 m. If the width of the parking lot is 65 m, what is its length? Length of the parking lot:

**Answer:**

79 m

**Step-by-step explanation:**

We know that

Perimeter of rectangle = 2(l + b)

=> 288 = 2(l + 65)

=> 288/2 = l + 65

=> 144 = l + 65

=> 144 - 65 = l

=> 79 = l

Hence,

Length of rectangle is 79 m

**Answer:**

Length of parking lot = 79m

**Explanation:**

2 × length + 2 × breadth = perimeter of rectangle

2 × length + 2 × 65 = 288

2 × length + 130 = 288

2 × length = 288 - 130

= 158

length = 158 ÷ 2

= 79
