Answer:
235 miles per hour and 2,115 miles in 9 hours
Step-by-step explanation:
First determine how many miles the jet files in one hour:
470/2 =235 miles/hour
We want to know how many hours the jet could fly in 9 hours, so we multiply this value by 9.
235 x 9 = 2115 miles
Therefore, the jet could fly 2115 miles in 9 hours.

Step-by-step explanation:
We know that to find the radius, we divide the diameter by 2, so the first one is correct.We know that the second one is incorrect because we just said that we would divide the diameter by 2 for the radius, so we would multiply the radius by 2 to find the diameter.The third statement is correct because the circumference is approximately 3 times bigger than the diameter.The fourth statement is correct because the circumference is equal to pi times 2 times the radius.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
2) Mateo scored 99 out 150 on an exam. What’s his score as a percentage?
Answer:
You divide the smaller number by the bigger, or the received points out of the total, so you would divide 99 by 150 giving you 66%
Answer : 66%
Explanation : 33 ÷ 50 Or 99 ÷ 150

2 2/5w = 21 3/5
Answer:
w = 9
Step-by-step explanation:
Firstly, change the mixed numbers to improper fractions, that is
[tex]\frac{12}{5}[/tex] w = [tex]\frac{108}{5}[/tex] ( multiply both sides by 5 )
12w = 108 ( divide both sides by 12 )
w = 9
Answer:
w=9

What is the average rate of change of the line whose equation is:
y−3=−12(x+4)?
PLEASE HELPPPP
Answer:
Rate of change = -12
Step-by-step explanation:
y − 3 = −12(x + 4)
Expanding, we have;
y - 3 = -12x - 48
y = -12x - 48 + 3
y = -12x - 45
Now, formula for rate of change is;
Rate of change = (y(x + h) - y)/h
y(x + h) is; y = -12(x + h) - 45
This gives;
Rate of change = (-12(x + h) - 45 + 12x + 45)/h
Rate of change = (-12x - 12h - 45 + 12x + 45)/h
Rate of change = -12h/h
Rate of change = -12

A rocket is launched upwards from the ground. The height of the rocket above the ground is
shown in the following table:
(a) Write the quadratic regression equation that models the data. Let x = time in seconds
and let y= height in feet. Round all numbers to the nearest hundredth.
(b) Use the equation to estimate the height of rocket after 5 seconds.
The height of the rocket after 5 seconds would be 0 feet.
What is an quadratic equation?A quadratic equation is in the form:
y = ax² + bx + c
Let y represent the height after x seconds.
At point (0, 0):
0 = a(0)² + b(0) + c
c = 0
At (0.5, 20.5):
20.5 = a(0.5)² + b(0.5) +0
0.25a + 0.5b = 20.5
At point (2, 36.25):
30.41 = a(2)² + b(2) + 0
4a + 2b = 30.41
Hence:
a = -17.2, b = 49.6
Hence:
y = -17.2x² + 49.6x
At 5 seconds:
y = -17.2(5)² + 49.6(5) = -197
The height of the rocket after 5 seconds would be 0 feet.

On a plane, 2/5 of the passengers were British. 30% of the British passengers were men. There were 36 British men on the plane. Find the total number of passengers on the plane
Answer:
76 passengers
Step-by-step explanation:
100-36 is 64 and that makes 64 + 36 =100-30 is 70% and we have 36 + 40 =76
There were 300 passengers.
What is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
Given:
Fraction of British = 2/5
Percent of British men = 30%
Number of British men = 36
let the British passenger be x
30 /100 * x= 36
x=120
and let the total passenger by y
2/5 of y = 120
y= 120 * 5/2
x= 300
Hence, there were 300 passengers.
