Step-by-step explanation:
Let
- y- the amount of charge,
- x - the number of miles
The equations as per question are below
<u>Crazy Curly's</u>
<u>Bill's Beauties</u>
Solve the system by substitution
- 0.3x + 20 = 0.2x + 50
- 0.3x - 0.2x = 50 - 20
- 0.1x = 30
- x = 30/0.1
- x = 300
Answer:
3500 tons
Step-by-step explanation:
The Greenpoint factory produced 2/5 of the bricks that the Consolidate Brick Company produced in 1991.
Let the amount of bricks produced by the Greenpoint factory be g and the amount of bricks produced by the Consolidated brick company be c.
Therefore:
g = 2/5 * c = 2c/5
That year, the Greenpoint factory produced 1400 tons of bricks. This implies that:
1400 = 2c/5
To find the amount that the Consolidated Brick Company produced, solve for c:
1400 = 2c/5
1400 * 5 = 2c
7000 = 2c
c = 7000 / 2 = 3500 tons
The Consolidated Brick Company had a total production output of 3500 tons in 1991.

Answer:
D. The data are discrete because the data can only take on specific values.
Step-by-step explanation:
<u>Continuous variables</u> are variables that can take on any value in an interval. Examples of continuous variables are length, time, etc.
<u>Discrete variables</u> on the other hand are variables that can only take on specific values.
The durations of movies in minutes<u> can only take on integer values from 0 to 60.</u> Therefore, it is a discrete data.
The correct option is D.
