Answer:

A. 200 miles/hour

Step-by-step explanation:

600 divided by 3, since division is the opposite of multiplication we can multiply:

3 X 150 = 450

3 X 50 = 150

we can add 150 and 50 together to get 200 and that's your answer

About how many years will it take for $4000 to double at a simple interest rate of 9%

Aleksandr [31]

Answer:

about 11 years

Step-by-step explanation:

we know that

The simple interest formula is equal to

$A=P(1+rt)$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=?\ years\\ P=\$4,000\\ A=\$8,000\\r=9\%=9/100=0.09$

substitute in the formula above

$8,000=4,000(1+0.09t)$

solve for r

$2=(1+0.09t)$

$0.09t=2-1$

$0.09t=1$

$t=11.1\ years$

T/(5/12)=(-3/10)<br> what is t ???

andrew11 [14]

Answer:

t = - $\frac{1}{8}$

Step-by-step explanation:

Given

$\frac{t}{\frac{5}{12} }$ = - $\frac{3}{10}$

Multiply both sides by $\frac{5}{12}$

t = $\frac{5}{12}$ × - $\frac{3}{10}$ ← cancel 5 and 10 by 5 and 3 and 12 by 3, leaving

t = $\frac{1}{4}$ × - $\frac{1}{2}$ = - $\frac{1}{8}$
