Answer:
Assuming the cones are the same height, then
V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3
V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3
V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3
V1/V2 = 1/6.25 = .16
V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)
V2/V1=6.25/1 = 6.25
Answer:
X+7
Step-by-step explanation:
If the youngest child's age expression is X+3 then the middle child's would be x+5 and the oldest would X+7. Even numbers have a difference of 2 between them and that is why 2 is gradually added to each age expression. Hope that helps.
The correct answer is B) <span>x + 4 = 3x + 6
Since both equations start with y = something, we can set the two equations equal to each other and solve.</span>
Answer:
19.21m is the diagonal
Step-by-step explanation:
We are looking for the diagonal, which makes it the hypotenuse of a right triangle, with the legs being 15 and 12
We can use the Pythagorean theorem
a^2 + b^2 = c^2
12^2 + 15^2 = c^2
144 +225 = c^2
369 = c^2
Take the square root of each side
sqrt(369) = sqrt(c^2)
19.209 =c
19.21 m = c
