Step-by-step explanation:
amount= simple interest + money deposited
SI= PRR/100
SI=(6000×5+5.5)÷100
= 165000÷100
=1650
amount= 1560+6000=7650
Remark
The easiest way to do this is to find the radius of both spheres . That gives you the scale factor. The answer to the next two parts might surprise you.
Step one
Find the volume of the small sphere.
V = 4/3 pi r^3
V = 250 yards^3
pi = 3.14
r = ???
Sub and solve
250 = 4/3 pi * r^3 Multiply both sides by 3/4 to get rid of the fraction on the right.
250 * 3/4 = pi * r^3
187.5 = pi r^3 Divide by pi
187.5 / pi = r^3
59.71 = r^3 Take the cube root of both sides.
cube root (59.71) = cube root(r^3)
r = 3.91
Step 2
find the radius of the large sphere.
I'm just going to give you the answer. Follow the above steps to confirm it.
V = 686 cubic yards
pi = 3.14
r = ??
r = cube root (514.5/3.14)
r = 5.472
Step 3
Find the ratio
r_large/r_small = 5.472/3.91 = 1.3995
I'm going to leave the Area calculations to you
The area ratios should come to 1.96 (about)
The volume ratios should come to 1:2.74
Answer:
10 hotdogs for $5.00 is the better deal
Step-by-step explanation:
Let's find the price of 1 hotdog if 8 hotdogs cost $4.08.
$4.08 ÷ 8 = $0.51 per hotdog
Now let's find the price of 1 hotdog if 10 hotdogs cost $5.00.
$5.00 ÷ 10 = $0.50 per hotdog
$0.50 per hotdog is slightly cheaper than $0.51 per hotdog, so 10 hotdogs for $5.00 is the better deal.
The margin of sampling error is obtained by multiplying the standard error with the critical value.
<h3>What is the margin of sampling error?</h3>
The margin of sampling error is a statistic that tells a researcher by how many percentage points the result gotten from the sample value would differ from that of the population. This value is obtained by multiplying the standard error with the critical value.
