For moves less than 50 miles, a moving company charges $180 per hour and a $50 gas fee.
Which function rule represents the amount in dollars, C, the company charges for h hours?
A:OC=50h - 180
B:OC=50h+ 180
C:OC=180h+ 50
D:OC= 180h - 50
Answer:
C
Step-by-step explanation:
the 50 miles don't really matter in this situation. 180$ per hour will be 180h (as we don't know the number of hours used) and the 50$ gas fee, which is what C is representing.
Answer:
C: C = 180h + 50
Step-by-step explanation:
180 per hour, with h representing how many hours, and then you need a $50 gas fee. So, the answer would be C = 180h + 50
Angles P and Q are complementary.
Angle P =2x
Angle Q =7x
Find the value of x. What is the measurement of Angle P? What is the measurement of Angle Q?
Answer:
Explained below.
Step-by-step explanation:
Complementary angles are angles that sum up to 90°.
Here,
Angle P = 2xAngle Q = 7xThen,
Angle P + Angle Q = 90°
2x + 7x = 90°
9x = 90°
x = 90/9
x = 10°
Therefore,
Measurement of Angle P = 2x = 2*10 = 20°Measurement of Angle Q = 7x = 7*10 = 70°[tex]\rule{150pt}{2pt}[/tex]

Determine the intercepts of the line.
Y-intercept: ( __ , __ )
X-intercept: ( __ , __ )
Answer:
x-intercept : (-1.2,0)
y-intercept : (0,-0.7)
Step-by-step explanation:
Hello!
An x-intercept is when the y-value is 0, and a y-intercept is when the x value is 0.
Another way to think about it, x-intercepts intersect with the x-axis, while the y-intercept intersects with the y-axis.
A coordinate, a point on a graph, is written as (x,y) or x-position and y-position.
x-intercept : (-1.2,0)
y-intercept : (0,-0.7)
You are collecting data to find out what the most popular lunch choice is. Each lunch period, you ask 15 students who buy lunch. There are 4 lunch periods a day. 25 students choose pizza. If there are about 600 students who buy lunch each day, about how many can you predict will buy pizza?
Answer:
250
Step-by-step explanation:
1. Find the total amount of people interviewed
You asked 15 students over 4 periods of lunch. That means you have to multiply:
15 x 4 = 60. You asked 60 people total.
2. Solve
You know that 25 people chose pizza out of the 60 people that you interviewed. That would make a fraction: 25/60
Now, there are 600 people, and the question is asking you how many people will get pizza based on the ratio of 25/60
So, in this case, 25/60 = x/600
You have to multiply 60 by 10 to get 600 as your denominator.
So, similarly, you have to multiply 25 by 10 to keep the same ratio.
25 x 10 = 250
Hence, 250/600 people will buy pizza.

The maker of a cell phone screen protector would like to estimate the proportion of customers who file a warranty claim. To do so, they select a random sample of 200 customers and determine that the 96% confidence interval for the true proportion of customers who file a warranty claim to be 0. 15 to 0. 28. Which of these statements is a correct interpretation of the confidence level?
Approximately 96% of customers file a warranty claim.
The cell phone screen protector maker can be 96% confident that the interval from 0. 15 to 0. 28 captures true proportion of customers who file a warranty claim.
If many random samples of size 200 are selected from the population of all customers, approximately 96% of the sample proportions of customers who file a warranty claim will be between 0. 15 and 0. 28.
If many random samples of size 200 are selected from the population of all customers, about 96% of the intervals constructed from the samples would capture the true proportion of customers who file a warranty claim
According to the interpretation of the confidence interval, the correct statement is:
The cell phone screen protector maker can be 96% confident that the interval from 0.15 to 0.28 captures true proportion of customers who file a warranty claim.
What is the interpretation of a x% confidence interval?It means that we are x% confident that the population parameter(mean/proportion/standard deviation) is between a and b.
In this problem, we have a 96% confidence interval between 0.15 and 0.28, hence we are 96% confident that the population proportion is between these values, and the correct option is:

Chris and Sam earn money shoveling snow, as described below. The amount of money Chris earns can be modeled by the equation y=8.25x, where the y is the total amount of money, in dollars, earned in x hours. The table below shows the relationship between the total amount of money earned,y, in dollars, and the total amount on time worked, x, in hours, for Sam.
Based on the data given on the amounts Chris and Sam are paid, we can infer that Chris earns $0.75 more per hour than Sam.
How much do Chris and Sam earn?Chris earns $8.25 an hour according to the equation that shows how he is paid of y = 8.25x.
The amount earned by Sam can be found as:
= Any value of y / Corresponding value of x
= 30 / 4
= $7.50 per hour.
The difference between their pay is:
= 8.25 - 7.50
= $0.75

A person can travel at the speed of 40 miles per hour (mph). If the speed is increased by 50%, how long will it take to cover 330 miles?
a. What is asked? How long will it take to cover 330 miles travelling at a speed 50% greater than 40 mph
b. What are the given facts?
Current Speed = 40 mph
New Speed = 40 mph + 50% of 40 mph

Calculate the new speed and then use the two speeds to calculate time based on Distance = Speed x Time
What is the formula to solve the problem?
Distance = Speed x Time
3. Solve
Show your solution.
Original Speed = 40 mph
New Speed = 40 + (0.5)*(40): New = 60 mph
Time at New Speed is:
Distance = Speed x Time
330 miles = (60 mph)*(Time)
Time = (330 miles)/(60 miles/hour)
Time = 5.5 hours
4. Check
Distance = Speed x Time
How far does a person travel going 60 miles/hour for 5.5 hours? Is it 330 miles?
