The best thing to do is to split the answer up, so (0.3*4) and (0.3*0.6), and then add them together;
0.3*4= 1.2
0.3*0.6= 0.18
1.2+0.18= 1.38
Therefore, 0.3*4.6 is equal to 1.38
Hope this helps :)
we know that
The simple interest formula is equal to
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
substitute in the formula above
solve for r
therefore
<u>the answer is</u>
the rate of interest is
Let's break apart the problem and solve it in bits.
10:45pm - 12:15am = 90 mins (1hr30)
So in a span of an 1hr and 30 minutes, she read 6.75 pages. To solve how many pages read per hour, set up a proportion and cross multiply:
90/6.75 = 60/x multiply 90 and "x" to get 90x, and 6.75 and 60 to get 405. We need to isolate the variable, and in order to do that, you must use the opposite operation of what the "x" is involved in. Here we have 90x ("x" is multiplied to 90) so we must divide. Divide 90 from 90x to cancel out the 90 and leave us with just "x".
What you do on one side, you must do to the other, so divide 405 by 90 to get 4.5.
Answer: x=4.5, or there were 4.5 pages read in an hour.
Answer:
2 in
Step-by-step explanation:
if 200 miles = 1 in
400 miles =<u> 400 miles x 1 in</u>
200 miles
= 2in
Which is more 4/5 or 0.71? Because decimals are usually easier to read, convert the 4/5 to a decimal. To do this, divide the numerator by the denominator. 4 / 5 = 0.8.
0.8 is bigger than 0.71. So, 4/5 is definitely bigger than 0.71.
But what about 1.2 and 1 2/9? Again convert 1 2/9 to a decimal.
2/9 = 1.222...
And 1.222 repeating is bigger than 1.2
