Answer:
See below
Step-by-step explanation:
Use pythagorean theorem to find the side of the triangle which is the side of the square
side = sqrt ( 8^2 + 4^2) = <u>sqrt 80 units = 4 sqrt 5 units </u>
area = sqrt 80 * sqrt 80 =<u> 80 units ^2 </u>
Sara drove 18 miles per gallon of gas.
72 miles ÷ 4 gallons of gas = 18 miles per gallon of gas
Answer:
- 10 2/3 years or 10 years and 8 months
Step-by-step explanation:
Assumed it is a simple interest with rate r.
<u>Find the rate:</u>
- 4000(1 + 8r) = 5000
- 1 + 8r = 5000/4000
- 8r = 1/4
- r = 1/32
<u>Find the time for the second amount:</u>
- 2100(1 + 1/32t) = 2800
- 1 + 1/32t = 2800/2100
- 1 + 1/32t = 1 1/3
- 1/32t = 1/3
- t = 32/3
- t = 10 2/3
we conclude that the linear equation in the graph is:
y = -2*x + 30
<h3>
How to find the equation in the graph?</h3>
We can define the variables:
- y = number of oranges.
- x = number of apples.
On the graph we can see two points:
(0, 30) and (15, 0).
Remember that a linear equation is of the form:
y = a*x + b
For the first point, we have:
30 = a*0 + b
30 = b
Then the line is:
y = a*x + 30
Now we can use the point (15, 0) to write:
0 = a*15 + 30
-30 = a*15
-30/15 = a = -2
Then we conclude that the linear equation in the graph is:
y = -2*x + 30

Answer:
I think you didn't specify what order this decimals you want to be so:
- If you want these to be in ascending order (lowest to highest), then:
- 3.5, 4.37, 8.93, 10.4, 14.2 and 17.86.
- If you want these to be in descending order (highest to lowest), then:
- 17.86, 14.2, 10.4, 8.93, 4.37 and 3.5.
Hope this helps and if you could mark me as brainliest. Thanks!
