What is the measure of c? A. 20 B. 14 C. 16 D. 22
1 answer:
Answer:
A
Step-by-step explanation:
The measurements of the segments fall on similar triangles. This means the lengths of each segment can be found using proportions.
Remember, a proportion is an equation which sets equal ratios equal to each other.
To solve for c, multiply numerators and denominators across the equal sign:
24c = 32(15)
24c = 480
c = 20

Answer:
436 items
Step-by-step explanation:
When a quantity A is inversely proportional to another quantity B, we can write:
Where k is the proportionality constant [that we need to find]
For this problem, we can write the ratio as:
Now given N = 480 and C = 4.90, we first find k:
Now, as second step, we need this time to find N, when
C = 5.40
Note, we know know k = 2352, so we find N:
Rounding to next whole number, we have 436 items
