<span>The question is asking us to calculate how many envelopes are there in 7 packages if there are 75 in a package. For example: in 1 package there are 75 envelopes. In 2 packages there are 7 * 2 = 150 envelopes. In general, formula is : 75 * n, where n is the number of packages. Therefore, we will multiply 75 by 7. 75 * 7 = 525. Answer: B ) 525 envelopes.</span>
Answer:
b = 17.55
Step-by-step explanation:
a^2 + b^2 = c^2
4^2 + b^2 = 18^2
16 + b^2 = 324
<u>-16 -16</u>
b^2 = 308
square root them
<u>b = 17.55</u>
let me know if it is correct!
Answer:
$1260
Step-by-step explanation:
Given data
You make $2,800 per month
Rent= 30% of monthly earning
=30/100*2800
= 0.3*2800
=$840
Transportation and foodt= 15% of monthly earning
=15/100*2800
= 0.15*2800
=$420
Hence the total expenses = 840+420
= $1260
Answer:
Step-by-step explanation:
given,
initial count of bacteria(P)=4,80,000 ,
increasing rate of bacteria(R)=2.5%,
time(T)= 2 hours
amount(A)=p(1+R/100)^T
A=480000(1+2.5/100)^2
A=480000*(1681/1600)
A=504300
therefore, the bacteria at the end of 2 hours is 504300(approx)
