5/6 of an hour is 50 min. So 50 times 3 equals 150 min for reading. 3/4 of an hour is 45 min. 45 times 2 equals 90 min for science. And 1/2 of an hour is 30 min. So 30 times 4 equals 120 mins for math. Add 150,90, and 120 min all together and you get 360 mins total. Divide 360 by 60, and you get 6 hours total that Michaela spent on reading, math, and science. Not 2 1/2.
5/8=0.625
4 and 5/8=4+5/8=4+0.625=4.625
you can just seperate the fractions and add
Answer:
infinite many
Step-by-step explanation:
hope this helps u
The answer is C.) <span>x^2-10x+25=0 </span>
You will have to use this formula:
<span>log(1 + rate) = {log(total) -log(Principal)} ÷ Years
</span>log(1 + rate) = {log(100,000) -log(21,600)} <span>÷ </span><span>Years
</span>log(1 + rate) = { 5 -4.3344537512} / Years
log(1 + rate) =
<span>
<span>
<span>
{ 0.6655462488} / 42
</span></span></span>log(1 + rate) =
<span>
<span>
<span>
0.0158463393
</span>
</span>
</span>
1 + rate = 10^<span>
<span>
0.015846339
</span></span><span>1 + rate = </span>1.0371613856
rate = .0371613856<span>
rate = </span><span>3.71613856%
</span>************************************************************************
Double-Check
Total = principal * (1 +rate)^years
Total = 21,600 * (<span>1.0371613856)^42
</span>
<span>Total = 21,600 * </span>
<span>
<span>
<span>
4.6296296291
</span>
</span>
</span>
<span><span>

</span>
Total = 100,000
Correct !!
