Two trains are traveling at constant speeds on different tracks.
Answer:
Train B is traveling faster
Step-by-step explanation:
From the picture, we want to know which train is traveling faster
We can know this by knowing the speed of the trains
Mathematically;
speed = distance/time
Train A
12.5 m in 1 second
speed = 12.5/1 = 12.5 m/s
Train B
100 m in 4 seconds
speed = 100/4 = 25 m/s
So train B is traveling faster
This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m
in 1 second

The volume of a rectangular prism is 240 cm3. The height and width are each 4 cm. What is the length?
Answer:
length is 15 cm
Step-by-step explanation:
4 * 4 * x = 240
16x=240 : divide by 16 on both sides
x = 15
then to check
15 cm x 4 cm x 4 cm = 240 cm^3

by cross multiplication
15×1 =n×3
15=3n
so
n=15÷3
n=5
F(-4)=-8 and f(-8)=-11
Answer:
f=2 and f=11/8
Step-by-step explanation:
Let's solve your equation step-by-step.
f(−4)=−8
Step 1: Simplify both sides of the equation.
−4f=−8
Step 2: Divide both sides by -4.
−4f
−4
=
−8
−4
f=2
Let's solve your equation step-by-step.
f(−8)=−11
Step 1: Simplify both sides of the equation.
−8f=−11
Step 2: Divide both sides by -8.
−8f
−8
=−11/−8
f=11/8

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
y = -1/4x + 4
Step-by-step explanation:
x+4y=28
4y = -x + 28
y = -1/4x + 7
slope m = -1/4
Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.
y = mx +b
2 = -1/4(8) + b
2 = -2 + b
b = 4
Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.
y = mx + b
y = -1/4x + 4
cheetah can run 70 miles per hour. What is this speed in feet per hour? *
Answer:
369600 feet per hour
Step-by-step explanation:
1m = 5280ft
5280 x 70 = 369600
Answer:
369,600 feet per hour
Step-by-step explanation:
1 mile = 5,280 feet
70 mph (cheetah's speed) x 5,280 feet (feet in 1 mile) = 369,600 feet (cheetah's speed in feet)

Answerr for money!!!
Answer:
Line s and Line t are parallel.
Step-by-step explanation:
Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.
By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.
I hope you find my answer and explanation to be helpful. Happy studying.
Please help! :(

5)A chef has 3 1/16
pounds of flour in his kitchen. He buys
another 6 1/2
pounds of flour. How much flour does he
have in all?
Answer:
9 9/16
