Zinaida [17]

Answer:

3.92 × 10 ^18

Step-by-step explanation:

(7 x 10^*9)(5.6 x 10^*8)

(7000000000)(560000000)

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  

10

If the decimal is moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

How to find the area of 2 half circles and a rectangle
gladu [14]
Hello!

We use different formulas to calculate the areas of different shape.

RECTANGLE:

To find the area of a rectangle, we must simply multiply its length by its width. The formula for its area is:

A = l × w

SEMICIRCLE:

Since the formula for a circle is pi × r × r, we must use the same formula but divide it in half, because a semicircle is a half circle, which is why its area would also be half of a circle's. The formula for a semicircle's area is:

A = 1/2 pi × r × r

Tip:

Write these formulas down and memorize them so that you don't forget them. You'll have to use these formulas quite often when finding the area of these shapes.

A recipe calls for 2 1/2 Cups of flour and four eggs. If only three eggs are used, how many cups of flour should be used? Give y
MAXImum [283]

Answer:

Step-by-step explanation: write the equation in the form of a proportion

2 1/2 is to 4 as something is to 3

2 1/2 / 4 = x/3

Then, cross multiply 2 1/2 x 3 or

5/2 x 3/1 = 15/2

Next cross multiply 4•X= 4X

Write as 4X = 15/2

Divide both sides by 4.

4X/ 4 = 15/2 /4

x = 15/2÷ 4/1

Divide by changing the sign to multiplication and inverting 4/1 to 1/4 like this:. 15/2. × 1/4= 15/8

Finally, 15/8 simplifies to 1 7/8 cups
