Answer:

Factoring out the GCF is the first step in many factoring problems. Step 1: Determine the greatest common factor of the given terms. The greatest common factor or GCF is the largest factor that all terms have in common. Step 2: Factor out (or divide out) the greatest common factor from each term.

Step-by-step explanation:

The score that represents the top 20% = A score = 80%

Z score for 80% percentile = 0.842

We solve using the z score formula

z = (x-μ)/σ, where

x is the raw score = ??

μ is the population mean = 490

and σ is the population standard deviation = 50

Hence:

0.842 = x - 490/50

Cross Multiply

0.842 × 50 = x - 490

x = 0.842 × 50 + 490

x = 42.1 + 490

x = 532.1

Approximately = 532

Therefore, the test score = 532

edg 2020-2021

Step-by-step explanation:

let w = width

length = 3w-2

perimeter = 2*length + 2*width

perimeter = 2(3w-2) + 2w

perimeter = 6w - 4 + 2w

perimeter = 8w - 4

perimeter = 124 inch

8w - 4 = 124inch

+4 to each side

8w = 128inch

divide each side by 8

w = 16

length = 3w-2

           = 3(16) - 2

length = 46 inch

Step-by-step explanation:

Given :

Height of patio, h = 8ft

Base of patio = 17 ft

Cost of carpeting = $6.50 per ft²

Area of triangular patio :

Area = 1/2 * base * height

Area = 0.5 * 17 * 8

Area of patio = 4 * 17

Area of patio = 68 ft²

Cost of carpeting :

Area of patio * contains st per ft²

68 * 6.50

= $442

Answer:

Step-by-step explanation:

5k + 30 = -20 - 5k

5k + 5k = -20 - 30

10k = -50 / : 10

k = -5

Answer:

-5 = k

Step-by-step explanation:

5k + 30 = -20 - 5k

5k + 30 + 20 = 5k + 50

-20 - 5k + 20 = -5k

5k + 50 = -5k

5k + 50 - 5k = 50

-5k - 5k = -10k

50 = -10k

50 / -10 = -5

-10k / -10 = k

-5 = k

Answer:

10.3 km

Step-by-step explanation:

Perimeter = side1 + side2 + side3

side1  = 2.7 km

side2 = 3.3 km

side3 = 4.3 km

Perimeter = 2.7 + 3.3 + 4.3

Perimeter = 10.3 km

Answer:

16

Step-by-step explanation:

-2 to the 4th power is expressed as;

= (-2)^-4

= -2 × -2 × -2 × -2

= (-2×-2)×(-2×-2)

= 4×4

= 16

Hence -2 to the 4th power is equal to 16

Answer:

She does not have enough milk to last for 1 week

Step-by-step explanation:

From the question, we are told that:

Bonnie's doctor recommended that she drink 2cups of milk per day.

Step 1

The number of days in a week is 7 days

Hence

1 day = 2 cups of milk

7 days = x

Cross Multiply

x = 7 × 2 cups of milk

= 14 cups of milk.

Step 2

If she buys 3 quarts of milk,will it be enough milk to last 1 week?

We have the conversion rate as:

1 quart = 4 cups

Therefore,

1 quart = 4 cups

3 quarts = x cups

Cross Multiply

x cups = 3 quarts × 4 cups/1 quart

x cups = 12 cups of milk

This means she bought 12 cups of milk.

Therefore, from the above calculation, she does not have enough milk to last for 1 week because due to her doctor's recommendation, she need 14 cups of milk for the week but she only bought 12 cups of milk

Answer:

$604.47

Step-by-step explanation:

Given data

Cost of camera= $560.99

Tax= 7.75%

Let us find the amount of the tax

=7.75/100* 560.99

=0.0775*560.99

=$43.48

Hence the amount of the tax is $43.48

Therefore the total cost is

=43.48+560.99

=$604.47
