Answer:
1857 miles.
Step-by-step explanation:
We have been given that the scale on a map is 1 cm:30 mi. The distance on the map between San Francisco, CA, and Chicago, IL, is 61.9 cm. We are asked to find the actual distance between San Francisco and Chicago.
We will use proportions to solve our given problem.
Upon substituting map distance between San Francisco and Chicago, we will get:
Therefore, the actual distance between San Francisco and Chicago is 1857 miles.
Answer:
1. 1/4 because rectangle B takes up 1/2 of the space and the two triangles together take up 1/4.
2. 1/2, because it is twice as big as C, which takes up 1/4 of the space.
3. 1/8, because both A and D together take up 1/4 of the space, and they are both the same size
4. 1/3, because the triangles around it each take up 1/6 of the space
5. 1/6, because it is half as large as square J, which takes up 1/3 of the space

Answer:
C)150
Step-by-step explanation:
P (blue) fraction = 2/8 decimal=.25 percent=25%
P(purple) fraction=0/8 decimal=0 percent =0%
P(not green) fraction=5/8 decimal=.625 percent= 62.5%
P(not brown) fraction=8/8 decimal=1 percent =100%
2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.
80% on time so 20% are not on time
20/100 ÷ 20 =1/5
20%, .2, 1/5
3)The spinner has 8 sectors labeled with letters. Each sector of the spinner below is the same size, as shown.
If the arrow is spun 400 times , how many times would it be expected to land on a sector labeled B?
A)50 C)150
B)100 D)250

To solve this problem, let us say that:
money invested in stock A = A
money invested in stock B = B
money invested in stock C = C
The given problem states that:
C = A * (1 / 4) = 0.25 A
B = A * (1 / 2) = 0.50 A
It was stated that we only have $16,000 to invest.
Therefore:
A + B + C = 16,000
Substituting values of C and B in terms of A:
A + 0.50 A + 0.25 A = 16,000
1.75 A = 16,000
A = $9,142.86
So C and B is:
C = 0.25 (9142.86)
C = $2285.71
B = 0.50 (9142.86)
B = $4571.43
