Answer:
the difference would be 28 degrees.
Step-by-step explanation:
The question says difference so we subtract the two following temperatures 30 and -2 which would be 28 degreees.
Answer: The difference between the high and low temperature in the thermometer is 32°F.
Step-by-step explanation:
Given information: Highest temperature = 30°F and the lowest temperature = -2°F.
We need to find the difference between the high and low temperature in the thermometer.
Difference between the high and low temperature is
Difference = Highest temperature - Lowest temperature
Difference = 30°F - (-2°F)
Difference = 30°F + 2°F
Difference = 32°F

A group of friends buys 15 movie tickets for a total of $147.66, which
includes a 7% sales tax.
Before tax, how much did a single movie ticket cost?
Answer: $9.20
Step-by-step explanation:
Divide the full tax price by the sales tax (7% or .07) plus 1 (always add 1 to the tax) thus
$147.66 / 1.07 = $138.00
So $138.00 is the full price without tax.
Now divide $138.00 by the amount of tickets (15) to find a single ticket price before tax!
138.00/15 = $9.20
Remember to always add 1 to the tax percentage above when dividing to get the *pre-tax* price.

What is: 1x2x3x4x5x6x7x8x9x10?
the answer is 3628800
The solution to the equation "1x2x3x4x5x6x7x8x9x10" is 362,880.
How to find the multiplication?This is a factorial, which is the product of all the positive integers less than or equal to a given number. In this case, the factorial is 10!, which is the product of all the positive integers less than or equal to 10.
To calculate 10!, use the following formula:
n! = n × (n - 1) × (n - 2) × ... × (3) × (2) × (1)
where n is the number to be taking the factorial of.
In this case, n = 10, so:
10! = 10 × (9) × (8) × (7) × (6) × (5) × (4) × (3) × (2) × (1) = 362,880
Therefore, 1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 = 362,880.

Answer:
r = 2 (answer C)
Step-by-step explanation:
Given: (p - q)/2 = 3, so (p - q) = 6
Next, rp - rq = 12 can be rewritten as r(p - q) = 12, or r(6) = 12

the points scored per game by a professional basketball player are represented by the box plot below if the player scores 9 points and 35 points in the next two games how is the median of the data set affected
Answer:
The median points per game is not affected.
Step-by-step explanation:
Compare the points scored in the two most recent games to the values given in the box plot to determine how the new values affect the median of the original data set.
The box plot for points scored indicates that the minimum points per game is 11, the maximum is 26 points, and the median is 21 points.
Since the median of 21 is between the two new values of 9 and 35, the median points per game is not affected by the new values.

A planet has a circular orbit around a star. It is a distance of 59,000,000 km from the centre of the star. It orbits at an average speed of 41,000 km/h. How many Earth days does it take the planet to orbit the star? Give your answer to 2 sf.
Answer:
380 days
Step-by-step explanation:
Problem in post:
The radius of the orbit of the planet is 59,000,000 km.
The orbit is circular, so the length of the orbit is the circumference of a circle with radius 59,000,000 km.
distance = circumference of orbit = 2(pi)r = 2 * 3.14159 * 59,000,000 km = 370,707,933 km
speed = 41,000 km/h
speed = distance/time
time * speed = distance
time = distance/speed
time = (370,707,933 km)/(41,000 km/h) = 9,042 hours
Now we convert hours into earth days.
1 earth day = 24 hours
9,042 hours * (1 day)/(24 hours) = 376.73 days
Answer: 380 days
Problem in comments:
Nina and Jo both ran an 8 km race.
Nina took 45 minutes to run the whole race.
Jo started the race 4 minutes later than Nina but caught up when they had both travelled 5 km.
If Nina and Jo both ran at constant speeds, what is Jo's speed to 2 dp?
Solution:
They met at 5 km. Let's find out how long it took Nina to run 5 km.
We can use a proportion.
(8 km)/(45 min) = (5 km)/(x)
x * 8 km = 45 min * 5 km
x = [(45 * 5)/8] min
x = 28.125 min
They met after Nina was running for 28.125 minutes.
Jo started 4 minutes after Nina, so Jo ran for 4 minutes less than Nina. Jo ran 5 km in 24.125 minutes.
speed = distance/time
speed = (5 km)/(24.125 min) * (60 min)/(1 hr)
speed = 12.43523 km/h
Answer: Jo's speed is 12.44 km/h

You're choosing between two car rental companies. Company A charges an initial fee of $15 with $.25 per mile, while Company B only charges $.50 per mile. How many miles will it take for both companies to have the same service price? What's this price amount? Use the following systems of linear equations to solve by graphing. Company A: y = 0.25x + 15 Company B: y = 0.50x
Which is correct:
A. 55 miles; $25
B. 62 miles; $35
C. 60 miles; $30
D. 58 miles; $29
Answer:
60 miles; $30
Step-by-step explanation:
Given:
y = 0.25x + 15 ...........Eq1
y = 0.50x.............Eq2
Where, x = miles and y = Total cost of ranting
Find:
Total cost of ranting.
Computation:
From Eq1 and Eq2
0.25x + 15 = 0.50x
0.25x = 15
x = 15 / 0.25
x = 60 miles
From Eq 2
y = 0.50(60)
