Answer:
see below
Step-by-step explanation:
Part 1:
(512) ^ 1/3
-------------------
(2197) ^ 1/3
8
-----
13
The scale factor is 8:13
Part 2
The ratios of the areas is related by scale factor squared
8^2
-----
13^2
64
------
169
Part 3
64 960
------ = ----------------
169 SA larger
Using cross products
64 * SA = 169 * 960
64 SA = 162240
Divide each side by 64
64 SA/ 64 = 162240 / 64
SA = 2535
2535 cm^2
In triangle ABC, angle A is a right angle, and angle B= 45 degrees. (also AC is 12 ft). What is the length of BC? If your answer is not an integer, leave it in simplest rascal form.
Answer:f(4)= 12
Step-by-step explanation:
Treat f(x) as y, y=2x + 4, y=12
Answer:
(3/2)x - 5 or 1.5x - 5
Step-by-step explanation:
y = mx + b
Whereas, m = slope, b = y intercept, and obviously x = the x variable.
We can find the slope by plotting the 2 points and using the rise-over-run method to give you 3/2 or 1.5.
We can find the y intercept by tracing a line through both points and to the y axis.
Hope this helps!
The quantity will decline by 15%.
<u>Step-by-step explanation:</u>
Elasticity of Demand = % Change in quantity / % Change in price
ð 1.50 = % change in quantity / 10
ð Percentage change in quantity = 15%
Percentage change in quantity shows an inverse relation with respect to the percentage change in price. In this case of ice-cream, a 10% jump in the price will result the quantity to fall by 15%.
