Answer:
0.15 is 15%
first 0.15 x 32 / 100 = 4.8
32 - 4.8 = 27.2 is the new price of the pan

Answer:
The total distance he walked was 17/10 miles or 1.7 miles.
Step-by-step explanation:
Ron's walk was divided into two parts, one that goes from his grandmother's house to the store and then from the store to his house. The total distance that he walked is given by the sum of the two separate parts, so in order to calculate how far he walked we will do as follows:
Total distance = 8/10 + 9/10
Total distance = 17/10 mile = 1.7 miles
The total distance he walked was 17/10 miles or 1.7 miles.
Answer:
1436.75504 or 1372/3π cm^3
Step-by-step explanation:
The volume of a sphere can be found using:
V = 4/3 πr^3
We know the radius is 7, so we can substitute 7 in for r
V = 4/3 π7^3
Evaluate the exponent
V = 4/3 π 343
If we want the answer in terms of pi, multiply the two other numbers, that are not pi: 4/3 and 343.
v= (4/3*343)π
v=1372/3π
If we want an exact answer, multiply 1372/3 and pi
v=1436.75504
So, the volume is 1436.75504 or 1372/3 π cm^3
Answer:
a. 81.5%
Step-by-step explanation:
The z-score for 400 is ...
Z = (X -μ)/σ = (400 -500)/100 = -1
The z-score for 700 is ...
Z = (700 -500)/100 = 2
The empirical rule tells you that 68% of the distribution is within ±1σ of the mean, and 95% is within ±2σ of the mean. Half of that first number is in the range Z = -1 to 0, and half that second number is in the range Z = 0 to +2. So, the probability you want is ...
(1/2)(68%) + (1/2)(95%) = 81.5% . . . . matches choice A
I hope you do not intend some sort of compounding.
Basically, 3000 per month for 40 years can be calculated by doing some simple maths. So 3000 x 12 to get for a complete year. Which is 36000. NOw we can multiply this value by 40 to get the correct amount. So that is 1440000.
Now five percent of this amount is 5 / 100 x 1440000 = 72000. So the final answer after adding 5 % would be 1512000.
