I believe that the answer is A (3,-2)

Answer:

80 minutes ; $25

Step-by-step explanation:

Let x = number of minutes

Plan A :

17 + 0.1x - - - (1)

PLAN B :

13 + 0.15x - - - (2)

Both plans will cost the same when ;

17 + 0.1x = 13 + 0.15x

Solve for X

0.1x - 0.15x = 13 - 17

-0.05x = - 4

divide both sides by - 0.05

-0.05x / - 0.05 = - 4 / - 0.05

x = 80 minutes

Amount :

17 + 0.1(80) = 17 + 8 = $25

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:

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

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:

D.40.96

Step-by-step explanation:

1-.01×2=.02

2-.02×2=.04

3-.04×2=.08

4-.08×2=.16

5-.16×2=.32

6-.32×2=.64

7-.64×2=1.28

8-1.28×2=2.56

9-2.56×2=5.12

10-5.12×2=10.24

11-10.24×2=20.48

12-20.48×2=40.96

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: $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

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:

$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:

$2.85

Step-by-step explanation:

Answer:

0.57

Step-by-step explanation:

no prob

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

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:

If two sides in one triangle are congruent to two sides of a second triangle, and also if the included angles are congruent, then the triangles are congruent. ... If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF.

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.

What does this even mean?
