Answer:

2.7 kg

Step-by-step explanation:

1. Because 1 kilogram is 1,000 grams, 18 kilograms is 18,000 grams.

2. Let's set up the equation to find how much 15% of 18,000 is.

  • \frac{15}{100} * 18000

3. (Solving)

  • \frac{15}{100} * 18000
  • \frac{3}{20} * 18000
  • \frac{54000}{20}
  • 2700

4. Now that we have 2,700 grams, let's convert it into kilograms:

  • 2700/1000
  • 2.7

Therefore, 15% of 18Kg is 2.7 kg.

Answer:

27/10, or 2 7/10 kg

Step-by-step explanation:

We first have the expression 15/100*18, which simplifies to 3/20*18. If we multiply and simplify, we get 27/10, or 2 7/10

Answer:

Step-by-step explanation:

If 3/4 of the lot was full and the lot holds 1000 vehicles, then there are 3/4(1000) in the lot.  3/4(1000) = 750.  That means there are 750 vehicles in the lot.  If 200 cars are in the lot, then 750 - 200 = 550 trucks.

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
svet-max [94.6K]

Answer:

100.3 units²

Step-by-step explanation:

✅Find the area of the parallelogram:

Area of Parallelogram is given as base × height

base = 10

height = 5

Area of Parallelogram = 10*5 = 50

✅Next, find the area of the two semicircles:

The two semicircles = 1 circle

Area of circle = πr²

r = 8/2 = 4

Area = π*4² = 16π = 50.3 (nearest tenth)

✅Area of figure = 50 + 50.3 = 100.3 units²

Solve for the exact value of x.
blsea [12.9K]

Answer:

\sqrt{89}

Step-by-step explanation:

Using the Pythagorean Theorem, if you take 8 and square it, you get 64.

You then take 5 and square it giving you 25.

add the 64 and 25 to get you 89 = x squared.

Then take the square roots of x. (Keep in mind, what you do to one side must be done to the other.)

Because 89 is not a perfect square, you can it it as the square root of 89.
