Answer:
A. 6 hours
B. No students studied for 6 hours
C. 4 students
(I’m just using a educated guess for B)
Answer:
<u>Use Pythagorean:</u>
<h3>#1</h3>
- x² = 16² - 8²
- x² = 192
- x = √192
- x = 12.73, not an integer
<u>Not a Pythagorean triple</u>
<h3>#2</h3>
- x² = 40² + 9²
- x² = 1681
- x = √1681
- x = 41
<u>It is a Pythagorean triple (9, 40, 41)</u>
<h3>#3</h3>
- x² = 6² + 13²
- x² = 205
- x = √205
- x = 14.32, not an integer
<u>Not a Pythagorean triple</u>
The proffesional runner can run 50/12 miles or 4 1/6.
To figure this out turn both mixed numbers into improper fractions (denominator x whole number + numerator) and multiply both of the improper fractions ( numerator x numerator denominator x denominator )
Question 14:
We are given that:
C = πd
To solve for d, we need to isolate the d on one side of the equation. This means that we need to get rid of the π next to the d.
In order to do so, we can simply divide both sides of the equation by π as follows:
C/π = πd/π
d = C/π .........> The first option
Question (15):
We are given that:
d = rt
To solve for r, we need to isolate the r on one side of the equation. This means that we need to get rid of the t next to the r.
In order to do so, we can simply divide both sides of the equation by t as follows:
d/t = rt/t
r = d/t.........> The third option
Hope this helps :)
