The answer is: A. 20.3
The explanation is shown below:
1. By definition, the sum of the length of the strings (The length of the blue segment and the length of the red segment) is equal to the length of the major axis (The black segment).
2. Based on this, you can write the following expression, where
is the length of the blue segment:

3. Now, you must solve for
, as following:


4. Therefore, the answer is the option A.
To find the area of a square is Base x Height.
Triangle is 1/2 base x height.
My favorite strategy is the criss cross method.

Take the numerator of the first fraction (2), and the denominator of the second fraction (8) and multiply them. The value 16 is now up on the left side, imaginary. (ALWAYS PUT THE PRODUCT ON THE SIDE WITH THE NUMERATOR) Now multiply the other diagonal. 3(7)=21. The 21 is on the right side. Now do 16 ? 21
Is it <, >, or =? The answer is <

Given data
On Monday, Jesse drank 3/4 of liter of water before jogging
and drank 3/5 of liter after jogging
In all, Jesse drank 3/4 and 3/5 liters of water
= 3/4+3/5
the lcm is 20
=15+12/20
=27/20
in mixed numbers(i.e a whole and a fraction together we have) we have

Answer:
99.7%
Step-by-step explanation:
we start by getting the z-scores for the values given
We can get the z-scores using the formula below;
z-scores = (x-mean)/SD
for 338.5;
z = (338.5-598.4)/86.7 = -2.99 approximately-3
for 858.5;
z = (858.5-598.4)/86.7 = 3
so we want to get the percentages that lie within 3 standard deviations from the mean
According to the empirical rule, the percentages within 3 SD of the mean is;
100-0.15-0.15 = 99.7%
