C. 9.1x10^9
D. 9.1x10^5

Answers

Answer 1

Answer: This is a classic example of Scientific Notation.
5.3 x 10^5 actually equals 530,000
3.8 x 10^4 actually equals 38,000
Since it is asking for the sum of the numbers you are adding.
Your new equation look like this:
530,000 + 38,000
= 568,000
now all you have to do is count the decimal points. You start from the end zero and count the spaces in between until you get to the tenths place. (Right behind the first number) There are 5
So your answer will be:
B. 5.68 x 10^5.

Answers

$Slope = (y_2-y_1)/(x_2-x_1) = (11-5)/(1-(-2)) = (6)/(1+2) = (6)/(3) = \boxed{\bf{2}}$

The answer is B) 2.

Hello!

Step-by-step explanation:

Slope: $(Y^2-Y^1)/(X^2-X^1)=(rise)/(run)$

$(11-5=6)/(1-(-2)=1+2=3)=(6)/(3)=2$

Slope is 2.

Answer is 2.

Hope this helps!

Mandy's square quilt measures 99 inches on each edge. How many yards of trim does she need to buy to go around the entire quilt?

Answers

we know that 1 yard equals 36 inches, so we need to know how many yards represent 99 inches, lets use a rule of three:
36 in ------> 1 yd
99 in ------> x

x = (99)(1)/36
x = 2.75
therefore 99 inches equals 2.75 yards and that is the amount of trim that Mandy needs to go around the entire quilt
