Answer:

<h3>The answer is 5.7 %</h3>

Step-by-step explanation:

To find the rate given the principal , time and interest , we use the formula

$r = \frac{100I}{pt} \\$

where

p is the principal

t is the time

I is the interest

From the question

Principal = $1,250

Time = 4 years

Interest = $285

We have

$r = \frac{285 \times 100}{4 \times 1250} = \frac{28500}{5000} = \frac{285}{50} \\ = 5.7$

We have the final answer as

Hope this helps you

Which is the value of the expression ((10^4)(5^2)/(10^3)(5^3))^3

dimulka [17.4K]

Answer:

Step-by-step explanation:

Let's set this up to see if we can simplify it a bit:

$(\frac{10^4*5^2}{10^3*5^3})^3$

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top. And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom. Now that looks like this:

$(\frac{10}{5})^3$

10 divided by 5 is 2, and 2 cubed is 8

There are between 90 and 115 cars in a parking lot. Exactly one-fourth of them are green. Exactly one-eighth of them have a stic

Schach [20]

There are 104 cars in the parking lot.

According to statement there are between 90 and 115 cars on the lot.

So, {X| 90 < x < 115} (This renders an infinite solution set finite)

AND exactly one eight of them have a sticker on the back, so the total number of cars must be evenly divisible by eight.

X ∈ {96, 104, 112,}

AND exactly one fourth of the cars are green, so the number of cars must be evenly divisible by 4. Here all above written numbers are divisible by 4. So, find the mean to calculate the number of cars in the parking lot.

x = (96+104+112)/3

x = 104

There are 104 cars in the parking lot.

HELLLLLLLLPPPP <br> The value of x is

NeTakaya

Angle QRT is an exterior angle to the triangle. The rule is that the exterior angle of a triangle is equal to the sum of its remote interior angles. Those remote interior angles are angle RTS and angle TSR. So our equation is $9x=(5x)+(9+x)$ . We can remove the parenthesis and simplify by combining like terms to get 9x = 5x + 9 + x and 9x = 6x + 9 and 3x = 9. That means that x = 3.
