B = 3 V / h

Multiply each side by h

Bh = 3 V / h *h

Bh = 3V

Divide each side by 3

1/3 Bh = 3V/3

If the simple interest on $5,000 for 4 years is $1,600, then what is the interest rate?

matrenka [14]

Answer:

0.08, or 8%

Step-by-step explanation:

The appropriate formula is i = p*r*t, where p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

We want to calculate r when i, p and t are known.

Solving i = p*r*t for r, we get r = ------------

p*t

The interest rate in this case is

$1600

r = ---------------- = 0.08, or 8%

The base of a triangle is 8 1 3 meters and the height of the triangle is the fourth root of 16 meters meters. What is the area o

just olya [345]

Answer:

The area of triangle is $8 \frac{1}{3}\ m^{2}$

Step-by-step explanation:

we know that

The area of a triangle is equal to

A=(1/2)bh

we have

b=8 1/3 m

convert to an improper fraction

8 1/3 m=(8*3+1)/3=25/3 m

The fourth root of 16 is equal to 2

$\sqrt[4]{16}=(2^{4})^{1/4}=2$

h=2 m

substitute

$A=(1/2)(25/3)2=25/3\ m^{2}$

convert to mixed number

$25/3=(24/3)+(1/3)=8+1/3=8 \frac{1}{3}\ m^{2}$

What is the solution to the inequality -13x+6<14-5x

kvv77 [185]

Answer:

x > -1

Step-by-step explanation:

$-13x+6$

$-13x+5x$

$-8x$

$\frac{-8x}{-8} >\frac{8}{-8}$

$x>-1$

* Remember that,

if you have a negative sign (-) infront of the x you have to change the direction of the inequality sign.

Hope this helps you .

Let me know if you have any other questions :-)
