Answer:
4
Step-by-step explanation:
Pythagorean Theorem
a^2+b^2=c^2
C is the hyptonuse A and B are legs.
a^2+3^2=5^2
a^2+9=25
a^2=16
a= sqrt16
a=4
Hope this helps!
3675. You multiply 105 700, then you multiply the answer by 0.05.
The answer would be "both groups show about the same average time"
Step-by-step explanation:
(a/b) + (c/d)
Find the common denominator. In this case, bd. So multiply the first fraction by d/d, and the second fraction by b/b.
(ad)/(bd) + (bc)/(bd)
Add the fractions.
(ad + bc) / (bd)
The answer is c because of Pythagorean’s theorem. a^2 + b^2 = c^2
So 5^2 + 12^2 = 13^2
25+144=169
