Answer:
Step-by-step explanation:
28 students all give $128
so,
![\sqrt[28]{128}](https://tex.z-dn.net/?f=%5Csqrt%5B28%5D%7B128%7D)
= v v=6
Each student gave 6 dollars. This is true due to the fact that
=6
28X6=128
F(x)=-2x^3-5
f(-2)=2(-2)^3-5
f(-2) = 2(-8)-5
f(-2)= -16-5
f(-2)=-21
(-2,-21)
g(x)=-3x+2
g(7)=-3(7)+2
g(7)=-21+2
g(7)=-19
(7,-19)
Because the actual dimensions of the board and the target are missing, let us supply the missing values.
Let:
radius of board = 6 inches
radius of target = 2 inches
Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi
Probability of hitting the target = 4pi / 36pi = 1/9
Therefore, there is a 1/9 chance of hitting the target on the board.
Answer:
7 pencils
Step-by-step explanation:
Let x equal the number of pencils Monica buys and y equal the number of pens.
The expression would then be 2x + 7y ≤ 35. Plugging in 3 for y:
2x + 7(3) ≤35
2x +21 ≤ 35
2x ≤ 14
x≤ 7
Answer: The volume will be raised to the 3rd power of whatever the length is scaled by.
When we are scaling a figure, it means we are multiplying the length of it by a scale factor.
Picture a rectangle that is 5 by 7, the area would be 35.
If we scale it by 3, it is now 15 by 21 and the area would be 315.
The length got 3 times larger, but the area got 3^2 times larger because it is in 2 dimensions.
If we were talking about a rectangular prism, the volume would be 3^3 times larger or 27 times larger!
For the cost of the ice cream, we would need to have some actual measurements of the cone.
