Write 80% as a decimal number and as a reduced fraction

Answers

Answer 1

Answer:

Decimal: 0.80      Reduced fraction: [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

Take 80% and move the decimal two place values to the left.

This makes 0.80              (The decimal point is where the percent sign is.)

0.80 is [tex]\frac{8}{10}[/tex]  because the 8 is in the tenths place value.

[tex]\frac{8}{10}[/tex] can be simplified by dividing both the numerator and the denominator by 2.

[tex]\frac{8}{10}[/tex] = [tex]\frac{4}{5}[/tex]

A rectangular park is 135 yards long and 90 yards wide.

Give the length and width of another rectangular park that has the same perimeter but a smaller area.

Answers

Answer:

l = 140 yards , w = 85 yards

Step-by-step explanation:

1). l = 135 yards , w = 90 yards

P = 2 × 135 + 2 × 90 = 450 yards

A = 135 × 90 = 12,150 yards²

2). l = 140 yards , w = 85 yards

P = 2(140 + 85) = 450 yards

A = 140 × 85 = 11,900 yards²

Answer:

width= 100 yards

length= 125 yards

given g(x) √x-4 and h(x) = 2x - 8
what are the restrictions on the domain of g • h?

x ≥ ____

Answers

Answer:

6

Step-by-step explanation:

Given : g(x) =   and h(x)=2x-8.

g*h(x) =(2x-8).

We have square root(x-6) in composite function f*h(x).

So, we need to find the domain, we need to check for that values of x's, square root(x-4\6) would be defined.

Square roots are undefined for negative values.

Therefore, we can setup an inequality for it's domain x-6≥0.

Adding 4 on both sides, we get

x-6+6≥0+6.

x≥6.

In △ACD, if AC ≅ AD, m∠A = (3x – 4)°, m∠C = (5x + 1)°, and m∠D = (7x – 27)°, find x and the measure of each angle. *

Answers

Answer:

x = 14

A = 38

B = 71

C = 71

Step-by-step explanation:

Since we have a triangle, the addition of the measure of all the measure of the angles give 180

Thus;

3x-4 + 5x + 1 + 7x-27 = 180

15x-30 = 180

15x = 180 + 30

15x = 210

x = 210/15

x = 14

To get the measure of each of the angles, we substitute for x

A = 3x-4 = 3(14) - 4 = 38

B = 5x + 1 = 5(14) + 1 = 70 + 1 = 71

C = 7x - 27 = 7(14) - 27 = 98-27 = 71

A.) how much does it cost to buy 5 tickets?


B.) How many tickets can buy with $130?

Answers

Answer:

A) $77.50

B) 8 tickets

Step-by-step explanation:

A) c(x) = 17.5x - 10

Substitute 5 for x

c(x) = 17.5(5) - 10

Multiply

c(x) = 87.5 - 10

Subtract

c(x) = 77.5

B) 130 is the cost, so substitute 130 for c(x)

130 = 17.5x - 10

Add 10 to each side to move the constants to one side

140 = 17.5x

Divide each side by 17.5 to isolate the variable

8 = x

At a department store, the price of a freezer is marked up 15% to $450.50.

What was the price of the freezer BEFORE the mark up?

Answers

Answer:

The price was $391.30.

Step-by-step explanation:

We can answer this using algebra:-

Let the original price be $x, then:

x + 15% of x = 450

x + 0.15x = 450

1.15x = 450

x = 450/1.15

x = 391.304

You can buy 8 apples at the Quick Market for $1.45. You can buy 6 of the same apples at Stop and Save for $1.22. Which place is the better buy?

.............................
Answer:
Quick Market is the better buy.
...........................
To solve this in your head:
1) You can see that "6 apples for (about) $1.20" is about 20 cents each.
2) For the other apples to be 20 cents each, the price for 8 would have to be about $1.60
3) Because the cost of 8 apples is less than $1.60, then the Quick Market apples are cheaper than the other ones.

 The Quick Market will be the place for better buy than Stop and Save.

Comparison of rates for better buy:    Find the rate of one unit.    Compare the rates to decide the better buy.

Given in the question,

   Total amount paid for 8 apples at The Quick Market = $1.45     Total amount paid for 6 apples at Stop and Save = $1.22

Rate of apples at The Quick Market = [tex]\frac{\text{Total amount paid}}{\text{Number of apples}}[/tex]

                                                            = [tex]\frac{1.45}{8}[/tex]

                                                            = $0.18125

                                                            ≈ $0.18 per apple

Rate of apples at Stop and Save = [tex]\frac{1.22}{6}[/tex]

                                                      = $0.20333

                                                      ≈ $0.20 per apple

      Since, $0.18 is less than $0.22, The Quick Market will be the place for better buy than Stop and Save.
