Answer: A, 102

Step-by-step explanation:

Okay so just find the big square and subtract the holes

big square is 30x20 which is 600

hole #1 is 20x5 = 100

hole #2 is a triangle so you first find the base and height which are 10 and 5 respectively. Then use the triangle area formula a = 1/2bh to find that the triangle's area is 25.

Subtract the holes now

600-100-25 = 475

1 Gallon = 200 square feet covered so divide 475 by 200 to find how many gallons should be used. It's 3 gallons since you can't just buy a fraction of a gallon (Unless your being weird).

One gallon is 34, so 3 gallons is 3*34 = 102

Or in other words... A

hope you learned and can incorporate these methods for future problems :D!

There are three numbers a, b, c, where a > b and b >c. Describe the positions of the numbers on a number line.

AfilCa [17]

In maths, the “>” sign means “greater than”, or “bigger than.” If we say A > B, that means (in English) “A is bigger than B.”
So, if A > B and B > C:
A is bigger than B, and B is bigger than C.

So the smallest would be C, since both A and B are bigger. Next is B, and biggest is A.

That is the order they would be in a number line: C - B - A

The measure of an angle's supplement is 44 less than the measure of the angle.

Luden [163]

Answer:

< 1 = 112 degrees

< 2 = 68 degrees

Step-by-step explanation:

< 1 = x

< 2 = x - 44

x + x - 44 = 180

2x = 180 + 44

x = 224/2

x = 112

You have$560 in an account which pays 4.8% compounded annually. If you invest your money for 8 years, then how many dollars of i

SCORPION-xisa [38]

Answer:

$ 254.85

Step-by-step explanation:

Total amount invested = $ 560

Interest rate = r = 4.8% = 0.048

Time in years = t = 8 years

The formula for compound interest is:

$A =P(1+\frac{r}{n})^{nt}$

Here,

A is the total amount accumulated after t years. P is the amount invested initially and n is the compounding periods per year. Since in this case compounding is done annually, n will be 1. Using the values in the above formula, we get:

$A=560(1+\frac{0.048}{1})^{8} = \$ 814.85$

Thus, the total amount accumulated after 8 years will be $ 814.85

The amount of interest earned will be:

Interest = Amount Accumulated - Principal Amount

Interest = $ 814.85 - $ 560 = $ 254.85

By the end of 8 years, $ 254.85 would be earned in interest.
