Assume the mattress have no width, only length.
By Pythagoras' Theorem, √(72^2 + 80^2) = 107.6 inches.
a. "The newer car is more expensive" is false. The leftmost graph is a graph of cost versus time; you can see that as you increase in age, the cost lowers (point B to point A).
b. "The slower car is larger" is true. Middle graph is the relevant one. You can see that as cruising speed increases, the size decreases. Point A is the larger car than point B
c. We have to use multiple graphs. We see that car A is the larger car from the middle graph but car A is older than car B from the left graph. So no, the larger car is newer is false.
d. A is the cheapter car and it carries more capacity. True
The error of percentage is the amount of error over the original amount.
In this case it is 22/95 (not 22 over 77 because 77 is not the original amount they expected to sell.
22/95 = .2315 or 23.2% to the nearest tenth of a percent
Perhaps your teacher just wants 23% as an the approximate error.
Answer: C) 0.833%
Step-by-step explanation:
Given: Cost price of house = $120,000
The rate of increase of its cost = 10%
Therefore, the increase amount of house per year =10% of $120,000
Now, the amount increase each month=
Let r be the rate of growth each month, then
r% of $120,000=1000
Answer:
18.85 inches
Step-by-step explanation:
Eq: 2πr
D/2=R
