1. To determine simple interest, we use the formula i=prt where i is the interest, p is the principal or initial amount, r is th

Andrews [41]

Step-by-step explanation:

To determine simple interest, we use the formula

$I=Prt$

where I is the interest, p is the principal or initial amount, r is the interest rate is in the unit of years and t is the time in years

When the times is 3 years , then we plug in 3 for 't' directly

$I=Pr(3)\\$

we know that 1 year = 12 months

Suppose, the time is given in months then we divide time 't' by 12

When the times is 4 months , then we plug in 4 for 't' and divide by 12

$I=\frac{Pr(4)}{12}$

we know that 1 year = 365 days

Suppose, the time is given in days then we divide time 't' by 365

When the times is 45 days , then we plug in 45 for 't' and divide by 365

$I=\frac{Pr(45)}{365}$

Solve the equation x = 5/3 (pie) (r^3) for r.

DENIUS [597]

Answer and Step-by-step explanation:

To solve for r, we need to get everything away from r. We can start off by moving five thirds, and pi.

$x = \frac{5}{3} \pi r^{3}$

Multiply each side by $\frac{3}{5}$ , then divide by $\pi$ (pi)

$\frac{3x}{5\pi } = r^{3}$

Now, take the cubed root of both sides.

$\sqrt[3]{\frac{3x}{5\pi } } = r$

^^ That is the answer.

The shoe store has twice as many black shoes as it does brown shoes. The total number of shoes is 66. How many brown shoes are t

fredd [130]

x=number of brown shoes
2x=number of black shoes (twice as many black shoes as brown shoes)
so x+2x=66
add like terms 3x=66
solve for x by dividing 3; x=22
so there are 22 brown shoes and 44 black shoes (2 x 22= 44)

What is wrong with the following equation: 8 + (6/2) = 17 - 5

Sidana [21]

8+6/2=17-5

We can start by reducing the fraction using basic division.

Remember, numerator divided by denominator.

6 \ 2 = 3.

Rewrite the equation-

8+3=17-5

It doesn’t matter which side of the equal sign you start with, but in this case I started with the right hand.

8+3= 11

Rewrite-

11=17-5

Now subtract.

17-5=12

Write the equality.

11=12.

This is false.

11≠12.
