Answer:
12.25.
Step-by-step explanation:
1) the formula of the volume given in the condition is:
V=2*2/7*10x.
2) If V=70, then
2*2/7*10x=70, where x=12.25.
Answer:
35
Step-by-step explanation:
Let x represent the HCF of the ages. Then we can have ax = 10 represent Lena's age, and bx can represent her dad's age.
The LCM will be abx = 14x, so we have ab = 14.
Factors of 14 are 1·14 and 2·7. Since the ratio of ages is between 30/10 = 3 and 45/10 = 4.5, we must have b/a in that range. This will be the case for ...
a=2, b=7
For a=2 and ax=10, we have x=5.
The dad's age is bx = 7·5 = 35.
You cannot use the Pythagorean Theorem to find the side of a equilateral triangle because you can only use it to find the side of a right triangle. The Pythaggorean Theorem only works for right triangles.
Answer is x is less than 4
