Answer:
- face: hemisphere
- hat: cone
Step-by-step explanation:
The diagram shows a cone atop a hemisphere. We associate the cone with the hat (because it is on top), and the hemisphere with the face.
The shapes use are ...
face: hemisphere
hat: cone
13 ). 2ab + 5ab x 2 - 18ab
2ab + 10ab - 18ab
- 6ab
Answer= - 6ab
If $36=75%,
That means we can divide both sides by three to get $12=25%,
And because 25x4 is 100, we multiply both sides of the equation by 4 to get $48=100%,
So the answer is $48 dollars.
This also worked for me but I’m not sure it’s the most reliable way:
36 ÷ 0.75 = 48
(amount after discount ÷ percentage that is remaining)
We are given the set of points
<span>{(1, 60), (2, 240), (3, 960), (4, 3840)}{(1, 60), (2, 240), (3, 960), (4, 3840)}
If w is the function name and t is the input variable, then the equation has the form
w = k a^t
Plugging in any two of the points to solve for k and a
Choosing </span>(1, 60) and (2, 240)<span>
60 = k a
k = 60 / a
240 = k a^2
Substituting
240 = 60/a (a^2)
a = 4
and
k = 60 / 4 = 15
The function is
w = 15 (4^t)</span>
