Kali trains for a race by running around a track. Each lap around the track is 400 METERS. She runs 4 KILOMETERS each day. How many laps around the track does Kali run in 3 days?

Answers

Answer 1

Answer: First step, is to work out how many laps she runs in 1 day.
To do this, we divide what she runs in one day, by the length of one lap
4km / 400m
TO make this easier, we change to units of one number to make them both the same
We will turn them both into meters
4km = 4000m (1km is equal to 1000m, therefore we multiply by 1000)

4000/400 = 10 laps per day

Now we want to find out how many laps are completed in 3 days
If 1 day is equal to 10 laps and we want 3 days, we multiply 10 laps by 3 days
10 x 3 = 30 laps

Kali runs 30 laps in 3 days

Answer 2

Answer: 30 laps each day.................................

What percent of 126 is 22?

Answers

17.46% of 126 is 22

Divide 22 by 126:
$22 / 126 = 0.1746$

Change the decimal into a percentage by multiplying the decimal by 100:
$0.1746 * 100 = 17.46$

The percentage of 22 out of 126 will be 17.46%.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage of 22 out of 126 is calculated as,

P = (22 / 126) x 100

P = 0.1746 x 100

P = 17.46%

Can we use the formula A = 1/2 × base × height to calculate the area of triangles that are not right triangles? Explain your thinking.

Answers

Answer:

Yes

Step-by-step explanation:

If you are looking for an area of a triangle that is not a right triangle, and it shows the height of that triangle (it should be a dotted straight line), than you can use the formula to get the area.

So if you know the base and height of a non right triangle, you can use the formula.

A glacier moves about 12 inches every 36 hours. About how far does the glacier move in 1 week?

Answers

$\begin{array}{cccccc}12in&-&36h&/:3\n\n4in&-&12h&/\cdot2\n\n8in&-&24h=1day&/\cdot7\n\n42in&-&7day=1week\end{array}\n\n\n\nAnswer:42\ inches.$

So first you would divide 12 in half to figure out how many inches it moves in 24 hours (or 1 day) which would be 6 inches every 24 hours. You then multiply 6 (inches per day) by 7 (# of days). You end up with 42 inches in 7 days. Hope this helps

What is the perimeter of a square that has an area of 3 inches squared

Answers

Answer: p=4a

Step-by-step explanation: EXAMPLE The area of a rectangle is length times width. Since a square's length is equal to its width, a square's area is equal to the length of one side times itself. So, reversed, the square root of the square's area gives the length of one side. In this case, the square root of 36 square centimeters is 6 centimeters. Again, since all four sides of a square are the same, its perimeter is equal to the length of one side times four. For a square with one side equal to 6 centimeters, the perimeter equals 24 centimeters. hope this helps
