Kenny is planning to plant a rectangular garden that is 10 feet longer than it wide. Kenny wants to find its width if its area is 200 square feet. Write an equation that models this problem?

Answers

Answer 1

Answer: Let the width be x, then the length is x + 10.
Area = length x width = x(x + 10) = 200
$x^(2) +10x = 200$
Solving the quadratic equation, we have that
x = 10 feet
i.e. the width is 10 feet.

I need help with math motion problems. Ex. Two cars left a shop. The first car travels 55 mph and left at 9:00 am. The other car left one hour later at 75 mph. At what time did the second car catch up with the first?

Answers

The whole story begins at 9:00 AM, so let's make up a quantity called ' T ',
and that'll be the number of hours after 9:00 AM. When we find out what ' T ' is,
we'll just count off that many hours after 9:00 AM and we'll have the answer.

-- The first car started out at 9:00 AM, and drove until the other one caught up
with him. So the first car drove for ' T ' hours.

The first car drove at 55 mph, so he covered ' 55T ' miles.

-- The second car started out 1 hour later, so he only drove for (T - 1) hours.

The second car drove at 75 mph, so he covered ' 75(T - 1) ' miles.

But they both left from the same shop, and they both met at the same place.
So they both traveled the same distance.

(Miles of Car-#1) = (miles of Car-#2)

55 T = 75 (T - 1)

Eliminate the parentheses on the right side"

55 T = 75 T - 75

Add 75 to each side:

55 T + 75 = 75 T

Subtract 55 T from each side:

75 = 20 T

Divide each side by 20 :

75/20 = T

3.75 = T

There you have it. They met 3.75 hours after 9:00 AM.

9:00 AM + 3.75 hours = 12:45 PM . . . just in time to stop for lunch together.

Is 2/6 greater than 2/8

Answers

yes 2/6 is greater than 2/8 because when simplified 2/6 is 1/3 and 2/8 is 1/4 1/3 is larger than 1/4 because 1/4 is equal to 25% while 1/3 is equal to 33% hope that helped

Yes it is.
2/6= 1/3
2/8= 1/4
1/3 is greater than 1/4.

Simplify: (8^2/3)^4

Answers

So, $(8^(2/3))^4$ simplifies to 16, it can be solved according to the process of simplification process

To simplify the expression (8^(2/3))^4, we follow the order of operations, which is to evaluate the exponent inside the parentheses first, and then raise the result to the power of 4.

Step 1: Evaluate the exponent inside the parentheses.

$(8^(2/3))$ means taking the cube root of 8 raised to the power of 2. The cube root of 8 is 2, so we have:

$(8^(2/3))$ = 2

Step 2: Raise the result to the power of 4.

Now, we have:

$(2)^4$ = 2 * 2 * 2 * 2 = 16

So, $(8^(2/3))^4$ simplifies to 16.
