Answer:

12.5 km per liter.

Step-by-step explanation:

We have been given that Lily's car has a fuel efficiency of 8 liters per 100 kilometers. We are asked to find fuel efficiency of Lily's car in kilometers per liter.

$\text{Fuel efficiency}=\frac{\text{Total distance traveled}}{\text{Total fuel}}$

$\text{Fuel efficiency}=\frac{\text{100 km}}{\text{8 liters}}$

$\text{Fuel efficiency}=\frac{\text{12.5 km}}{\text{liter}}$

Therefore, fuel efficiency of Lily's car is 12.5 km per liter.

Find the volume of the sphere

son4ous [18]

Given:

The radius of the given sphere = 1 unit

To find the volume of the sphere.

Formula:

The volume of the sphere of radius r is

$V = \frac{4}{3} \pi r^{3}$

Now,

Substituting r=1 and π=3.14 (as given), we get

$V = \frac{4}{3} (3.14)(1^{3})$ cube unit

or, $V = 4.187$ cube unit

Hence,

the volume of the cube is 4.187 cube unit.

( PLASE HELP ME) Solve the following equation.

vovikov84 [41]

Answer:

x = 2

Step-by-step explanation:

5(x-4) =-10

Distribute 5 by multiplying x and -4 by 5

5x - 20 = -10

Add 20 to both sides

5x - 20 + 20 = -10 + 20

5x = 10

Divide both sides by 5

5x ÷ 5 = 10 ÷ 5

x = 2

many credit card companies charge a compound interest rate of 1.8% per month on a credit card balance. Miriam owes $750 on a cre

mash [69]

The answer is E.

First you need to find the rate. You must divide 1.8 by 100

1.8/100 = .018

Then add 1.

.018 + 1 = 1.018

Then times the starting amount with 1.018. The starting amount 750

750(1.018) = 763.5.
As you can see, in option E that is the 2nd number.

Now we must find the next number.

You will do 750(1.018)^x

x represents the time.

763.5 was the first month.

750(1.018)^2 is the 2nd month.

750(1.018)^2 = 777.244 which is the 3rd number in option E

$186.86

Step-by-step explanation:

4 eggs cost:

1 dollar per dozen (12 eggs), so by unitary method (ratios), we can find cost of 4 eggs. Shown below:

$\frac{1}{12}=\frac{x}{4}\\12x=4\\x=0.33$

So, 4 eggs cost $0.33 approx

12 lb. flour cost:

2.50 dollar per pound, so 12 pounds would simply cost:

2.5 * 12 = $30

14 lb of sugar cost:

4.50 dollar per pound means 14 pounds would cost:

4.5 * 14 = $63

2 ready-made edible flowers cost:

5 cents for each flower means 2 flowers would cost:

5 cent = 0.05 dollars

0.05 * 2 = $0.10

We add all up to find cost of 1 cake. Shown below:

Cost of 1 cake = $0.33 + $30 + $63 + $0.10 = $93.43

Cost of 2 cakes = $93.43 * 2 = $186.86
