Thus , the answer is approximately 33 % . Determine the decrease in temperature by subtracting 50 from 75. The temperature decrease is equal to 25 degrees . To solve for the percent decrease , divide the decrease in temperature by the initial temperature and multiply by 100 % . This is shown below , ( 25/75 ) x 100 % = 33.33 %
Answer:
10
Step-by-step explanation:
The two triangles are similar. <span>When two </span>figures<span> are </span>similar<span>, the ratios of the lengths of their corresponding sides are equal. We use this fact in order to calculate the height of the bigger triangle. We do as follows:
QP / SL = MN / SL+SR
25 / SL = 35 / SL + 13
SL = 32.5
Area = height x base / 2
Area = SL x MN / 2
Area = 32.5 x 35 / 2 = 568.75
</span>
Start by squaring the numbers on both sides to get rid of the square root on both the left and right sides to get:
x + 5 = 5^2 – x
x + 5 = 25 – x
Then rearrange to make x the subject.
x + 5 = 25 – x
2x + 5 = 25
2x = 20
x = 10
