you have $550 in a savings account that earns 3% simple interest each year . how much will be in your account in 10 years?

Answers

Answer: $715

Step-by-step explanation:

Given : Principal amount (P)= $550

Interest rate (r)= 3% $=(3)/(100)=0.03$

Time period (t) =10 years

WE know that the formula of simple interest is

$S.I.=P\cdot\ r\cdot\ t$

$\n\Rightarrow\ S.I.=550\cdot0.03\cdot10\n\Rightarrow\ S.I.=\$165$

Now, the total amount in account after 10 years = Principal+ S.I.

Therefore, the total amount in account after 10 years = $\$550+\$165=\$715$

In 10 years that'd be .3% interest, so just multiply it by 550. Then add your answer to 550. So your answer would be 665.

(2) What is the solution to -9m = -45?
A) m = 5
B) m = -405
C) m = -5
D) m = 405

(3) Solve for u.
-14 = u ÷ 8
u =

(4) Solve for h.
-117 = -9h
h =

(5) Solve for q.
9/19 = 5
h =

Answers

1) In order to solve the equation n/6 = -11.9, you must multiply by 6.

2) $-9m = -45 \n \n m = (-45)/(-9) \n \n m = (45)/(9) \n \n m = 5 \n \n Answer: \fbox {m = 5}$

3) $-14 = (u)/(8) \n \n -14 * 8 = u \n \n -112 = u \n \n u = -112 \n \n Answer: \fbox {u = -112}$

4) $-117 = -9h \n \n (-117)/(-9) = h \n \n (117)/(9) = h \n \n 13 = h \n \n h = 13 \n \n Answer: \fbox {h = 13}$

5) $(q)/(19) = 5 \n \n q = 5 * 19 \n \n q = 95 \n \n Answer: \fbox {q = 95}$

a survey conducted in a school showed that 65% of the students walked to school. The remaining students took buses to school. The ratio of students who took school buses to those who took public buses was 4:3. There were 360 more students who walked than took buses. How many students took public buses to school. Explain what and why you did what you did.

Answers

This means 35% used buses. 3+4=7, so 20% took school buses while 15% took public buses. 65%-35%=30% who mean the difference, so 30% is 360. You ask what is 15% -- that's half of that difference, or 180.
