Answer:
<em>Project 4 Score ; 41</em>
Step-by-step explanation:
Assuming that Project 4's score is x;
( Project 1 + Project 2 + Project 3 + Project 4 ) / 4 ⇒ take to substituting the value of each Project, provided Project 4's score being x;
45 = 42 + 49 + 48 + x / 4 ⇒ combine like terms,
45 = ( 139 + x ) / 4 ⇒ let 4 be a common denominator among numerator terms,
45 = 139 / 4 + x / 4 ⇒ divide 139 over 4,
45 = 34.75 + x / 4 ⇒ subtract 34.75 from either side,
10.25 = x / 4 ⇒ Multiply either side by 4,
x = 41 = Score of Project 4,
<em>Solution; Project 4 ⇒ 41</em>
Answer:
fwoggy
Step-by-step explanation:
Supposing the temperature of 60 degrees increases twice, it becomes 120 degrees (100% increase) and the bottles increase twice as well to 150 bottles (100% increase).
If there are 120 bottles used, we can calculate the temperature using the above assumption when bottle usage increase to 100% which is 150 bottles.
120 bottles/ 150 bottles = 0.8 or 80%
So, if 100% increase in temperature is defines by 120 degrees, what is 80% of 120 degrees?
Then 120 degrees divided by 0.8 will result to 96 degrees (so the answer is letter D) -- the temperature when 120 bottles were used by athletes.
The sum of opposite angles are equal, so two of the angles are 45°. The sum of all angles about the intersection of two lines is 360°. So the remaining two angles are found by:
α=(360-2*45)/2
α=135° thus all four angles are:
45°,135°,45°,135°
Answer:
<u> The total amount = $175</u>
Step-by-step explanation:
Let the total amount in his bank account = x
Nick decided to take 2/5 of the money in his bank account and donate it to a local charity
So, he donates with 
If nick donated $70 to a local charity
so, 
solve for x
∴ x = 5*70/2 = 350/2 = $175
<u>So, The total amount = $175</u>
