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:

532

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

Answer: $3,980

Step-by-step explanation:

As the question is asking for the amount that Genesis earned over the amount earned by David, to find the answer, subtract David's earnings from that of David.

= Genesis's earnings - David's earnings

= 72,832 - 68,852

= $3,980

2-.02×2=.04

3-.04×2=.08

4-.08×2=.16

5-.16×2=.32

6-.32×2=.64

Answer:

$442

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:

3.08×10 to the power of 4

Step-by-step explanation:

3.6×10the power of 6 =3,600,000

and 5.2× 10 to the power of 5 = 520,000

then the next step is to substract

3,600,000-520,000=308,000

then when we change it to decimal place we will get=3.08×10 to the power of 5

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

I had to look this one up  :) it seems too simple

10*6 = 5*x

60 = 5 x

60 /5 = x

12 = x

X = 12  

:)

Answer:

x=20

Step-by-step explanation:

Since all the angles in any give triangle adds up to 180, we can make an equation from this geometry question. x+5+7x-5+x=180 (Adding all the angles). If you simplify this, it becomes 9x=180, or x=20.

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

What does this even mean?

Step-by-step explanation:

Each year 50 new bulbs are added, so the gardener can expect that many added plants each year. So add 50 6 times and that will get to how many new bulbs will be added by 10 years time. More and more plants will be added each year and depending on which method the gardener chooses to use it will affect the buying amounts for each year as well as how many are bought.

I hope this helps! Good luck!

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

Answer:

For the economy as a whole, an improvement in technology shifts the production possibilities frontier outward. Production Possibility Frontier (PPF): An increase in technology that allows for greater output based upon the same inputs can be described as an outward shift of the PPF, as demonstrated in this figure.

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
