After 3.5 hours Kim had traveled 217 miles If she traveled at a constant speed how far will she have traveled after 4 hours

1 answer:

4 0

248 if i did my calculations correct because you already know kim traveled for 3.5 hours and got 217 miles traveled in that time so if you take 217 and divide it by 3.5 you get 62 and then you would take 62 and times it by 4 and your answer would be 248

Danny invested $350 at a rate of 2.5% for 3 years. How much interest did he earn on his investment?

Answer:

$26.91

Step-by-step explanation:

Assuming that the interest is compounded annually, we have the formula $A=P(1+r)^{t}$

A is the total amount.

P is the starting or principal amount

r is the rate, usually as a percentage

t is the times compounded

So, from the problem, we see that:

P = $350

r = 2.5% or 0.025

t = 3 yrs

Substituting variables, we get:

$A = (350)(1+0.025)^{3}$

$A=376.91$

So, our total amount is around $376.91, but they are asking us to find the <em>interest</em>. We subtract the total amount from the starting amount:

$376.91 - $350 = $26.91

You should check my answer though in case I make mistakes.

If one side of the square is 8 cm, that makes the area of the square 64 cm², because you just square a side to get the area of a square. A circle's area is π r², but this is a quarter circle, so it'll be 1/4 πr². The radius of this quarter circle is 8 cm, since it shares the side with the square. 1/4 π(8)² = 50.24 cm². Add the two areas together to get a combined area of 114.24 cm² for this figure. This is an approximation because pi (and therefore the area of the circle) is approximated.
Make sense?
