Pls explain tooo
Working together ,Ann and Jane painted a total of 480 square feet in 3 hours they each painted the same num of sq feet what is the average rate that ann and Jane each painted in square feet per hour
The average rate that Ann and Jane each painted is 80 square feet per hour.
What is rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity.
Now it is given that,
Total area painted by Ann and Jane = 480 square feet
Time taken in painting 480 square feet = 3 hours
Now let x and y be the amount painted by Ann and Jane.
Since,they each painted the same number of sq feet
⇒ x = y
Therefore, Total area painted = x + y = 2x
or, 2x = 480 square feet
⇒ x = 240 square feet
So, the same num of sq feet painted by both is 240 sq feet each
Now average rate = num of sq feet painted by each/time taken
⇒ average rate = 240/3 square feet per hour
or, average rate = 80 square feet per hour
Thus, The average rate that Ann and Jane each painted is 80 square feet per hour.

Identify all of the roots of the function f(x) = x^3 - 5x^2-2x+24
The roots are -2, 3 and 4.
What are roots?A solution to an equation, usually expressed as a number or an algebraic formula.
Given:
x³-5x²-2x+24
As, x+2 divides the x³-5x²-2x+24 gives quotient x²−7x+12.
Now,
x²−7x+12.
=x²− 4x -3 x+12.
=x(x-4) - 3(x-4)
=(x-4)(x-3)
Hence, the roots are -2, 3 and 4.

Samir begins riding his bike at a rate of 6 miles per hour. Twelve minutes later, Chris leaves from the same point and bikes along the same route at 9 miles per hour. How long after Chris begins riding does he catch up to Samir? 4 min 12 min 24 min 40 min
Answer:
The correct option is C) 24 min.
Step-by-step explanation:
It is given that:
Speed of Samir riding his bike = 6mph
Speed of Chris riding his bike = 9 mph
Let the time taken by Chris be x min. Then the time was taken by Samir be x+12
We know that the formula for the distance is
Where d is the distance, t is the time and r is the rate.
According to the question:
[tex]9x=6(x+12)\\9x=6x+72\\9x-6x=72\\3x=72\\x=24[/tex]
Hence, after 24 minutes Chris will catch up to Samir.
Therefore the correct option is C) 24 min.

(2x + 29) + 91 = 180.
This is because they add to form a straight line which is 180 degrees, in other words the angles are supplementary.
2x + 29 = 89 (Subtract 91 from each side)
2x = 60 (Subtract 29 from each side)
x = 30 (Divide 2 from each side)
x = 30

Question on a picture
Answer:
c = 0
Step-by-step explanation:
Step 1: Write equation
15 - 5(4c - 7) = 50
Step 2: Solve for c
Distribute -5: 15 - 20c + 35 = 50Combine like terms: -20c + 50 = 50Subtract 50 on both sides: -20c = 0Divide both sides by -20: c = 0Step 3: Check
Plug in c to verify it's a solution.
15 - 5(4(0) - 7) = 50
15 - 5(-7) = 50
15 + 35 = 50
50 = 50
