Answer:

<u><em>Stephanie runs the fastest per second: 14 feet per second</em></u>

Step-by-step explanation:

To find the fastest speed, you need to see which person runs the most per second:

Stephanie runs <em>14 feet per second</em>

<em />

Brooke runs 589 feet in 44 seconds.

Find the amount of feet per second by dividing:

\frac{589}{44} =13.4

Brooke runs about <em>13.4 feet per second</em>

<em />

Will runs 1 mile in 454 seconds.

Convert the miles to feet:

There are 5,280 feet in a mile. If Will runs 5,280 feet in 454 seconds, divide to find how much he runs per second:

\frac{5280}{454}= 11.6

Will runs about <em>11.6 feet per second.</em>

<em />

Rob runs 548 feet in a minute.

Convert the minute into seconds. There are 60 seconds in a minute. Divide the feet by the seconds to find how fast he runs per second:

\frac{548}{60}= 9.1

Rob runs about <em>9.1 feet per second.</em>

Stephanie runs 14 feet per second, the fastest time:

| 14 |, 13.4, 11.6, 9.1

<em>Finito.</em>

Kimane and a friend picked apples. Kimane picked 4 2/3 and his friend picked 5 5/6 pounds. About how many pound of apples do the
Gala2k [10]

Answer:

9\dfrac{1}{2}

Step-by-step explanation:

To find many more pounds of apples Kimane and his friend needs to get, we first need to find out how many pounds of apples they picked together.

Kimane = 4\dfrac{2}{3}

Friend = 5\dfrac{5}{6}

We add them together to find out how many pounds of apples they currently have.

Total Pounds = 4\dfrac{2}{3}+5\dfrac{5}{6}

Just to make the equation clearer, we separate the whole numbers from the fractions.

=4+5+\dfrac{2}{3}+\dfrac{5}{6}

=9+\dfrac{2}{3}+\dfrac{5}{6}

Now since we cannot add the 2 fractions directly since they have different denominators, we need to convert the /dfrac{2}{3} into a fraction with the same denominator.

We multiply both the numerator and denominator by 2 to have the same denominator.

\dfrac{2*2}{3*2}=\dfrac{4}{6}

So now we have:

=9+\dfrac{4}{6}+\dfrac{5}{6}

=9+\dfrac{9}{6}or1\dfrac{1}{2}

Total Pounds = 10\dfrac{1}{2}

Now that we know how many pounds Kimane and his friend collected, we simply subtract 20 and the total amount Kimane and his friend had already collected.

20-10\dfrac{1}{2}

=9\dfrac{1}{2}

So Kimane and his friend still need to get 9\dfrac{1}{2} more pounds of apples to get 20 pounds of apples.

Here's the result of this question
Marysya12 [62]

Answer:

B) Its final coordinates are (8,-6)

Step-by-step explanation:

1. Translated 1 unit up and 4 units left

(-2,7) becomes (-6, 8)

2. Reflected about the x-axis

(-6,8) becomes (-6, -8)

3. Rotated 90° anticlockwise about the origin

(-6, -8) becomes (8, -6) because when rotating 90 degrees anticlockwise about the origin, point A (x,y) becomes point A' (-y,x). In other words, switch the x and y and make y negative.
