Answer:
I think it may be the first one or the 3rd one! GOOD LUCK
We shall use the equation A = i(1 + r/n)^nt
So we shall plug all of that in so it turns out like this:
A = 4000(1 + 0.04/4)^4 x 7
So then that can be simplified to A = (1.01)^28
and then to A = 4000(1.321)
so then A = 5285.16
Answer:
store A has a better deal. as you can get 12 soda's for the price of $7.20
Step-by-step explanation:
3.60 x 2 = $7.20
Answer:
He average for this semester so far is 81 points.
Step-by-step explanation:
Since his score is 10% lower this semester than last semester, then he present score is 100% from the prior semester minus 10%, which equals to 90% of the previous semester. In order to calculate that percentage we can use a rule of three as shown below:
90 points -> 100%
x points -> 90%
100*x = 90*90
x = 8100/100 = 81
He average for this semester so far is 81 points.
Answer:
Step-by-step explanation:
Given:
Force, f = 9000 lb
Young modulus, E = 10,000,000 psi
Stress, S = 30000 psi
Elongation, x = 0.50 in
Length, L = 16 ft
Converting ft to in,
12 in = 1 ft
= 192 in
Young modulus, E = stress/strain
Stress = force/area, A
Strain = elongation, x/Length, L
Maximum stress = 30,000 psi
Stress = force/area
Area = 9000/30000
= 0.3 in^2
Using minimum area of 0.3 in^2,
A = (pi × d^2)/4
0.3 = (pi × d^2)/4
= sqrt(1.2/pi)
diameter, d = 0.62 inches
