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

Answers

They each painted 80 sq 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

Answers

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

Answers

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

Answers

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 = 0

Step 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

15 - 5(4c-7) = 50
15 - 20c + 35 = 50
50 - 20c = 50
-20c = 0

x = 0

i cant really explain stuff that well but basically you have to find the slope. you have to subtract 18-12 and you would get 6. then subtract -3-0 and that would be -3.

you then have to divide 6 (-3) and you would get -2. i never knew how to get 12 tho- sorry lol
