you run 1 mile in 8 minutes at a constant speed. How far do you run in 1 minute? write an equation to represent how far you can

Montano1993 [528]

Answer:

0.125

0.125x = Distance Traveled in Miles

0.125 * 11 = 1.375 Miles Ran

Step-by-step explanation:

First divide 1 mile by 8 minutes

1 mi / 8 min = 0.125 mi

Then you simply show 0.125 * x (x being the number you insert to find the distance) = How far you ran

0.125x = Distance Traveled in Miles

Finally you insert 11 for x and multiply to find the distance

0.125 * 11 = 1.375 Miles Ran

Deonte invested 200000at his bank for 10 years if he earned 130000 what was the interest rate the bank gave him

Volgvan

<u>Answer:</u>

The interest rate the bank gave Deonte is 6.5%.

<u>Solution:</u>

Given, Deonte invested 200000 at his bank for 10 years

He earned 130000

We have to find what was the interest rate the bank gave him.

Now we know that, simple interest $=\frac{\text {amount} \times \text {rate} \times \text {time}}{100}$

So, by substituting our values in above formula,

$130000=\frac{200000 \times \text { rate } \times 10}{100}$

Interest rate $\times$ 20000 = 130000

Interest rate $\times$ 2 = 13

$\text { Interest rate }=\frac{13}{2}=6.5 \%$

Hence, the interest rate given by bank is 6.5% to Deonte.

The remains of an ancient ball court include a rectangular playing alley with a perimeter of about 18m. The length of the alley

mariarad [96]

Given:

Perimeter = 18 m

The formula for the perimeter of a rectangle is:

$P=2l+2w$

Where:

l = lenght

w = width

In this case, we have that:

l = 2w

Therefore, we substitute the values in the formula:

$\begin{gathered} P=2l+2w \\ 18=2(2w)+2w \end{gathered}$

And solve for w:

$\begin{gathered} 18=4w+2w \\ 18=6w \\ \frac{18}{6}=\frac{6w}{6} \\ w=3 \end{gathered}$

For the length:

$l=2w=2(3)=6$

Answer:

The width is 3 m

The length is 6 m
