SA=2pi 2 40 + 2pi 4
SA=160pi+8pi
SA=168pi
or
SA=527.787566 yards cubed
Slope of JK = 2/3
Slope of KL = -3/2
Slope of LM = 2/3
Slope of MJ = -3/2
Important variables to know:
I = interest
P = principal (investment)
R = simple interest rate
T = years
Formula: I = PRT
What information do we have?
I = $960
P = $4000
T = 3 years
R = ?
Plug into formula:
960 = 4000(3)(R)
960 = 12000R
R = 960/12000
R = .08
A. $4000 + $960 = $4960. (A= P+ I)
B. 8% (.08)
Part 2: 1080 = 4000*.09*3
A = 5080 - 4960 =$420.
Answer:
x=19
Step-by-step explanation:
5(x+35)=9(300
5x+175=270
5x=270-175
5x=95
95/5=19X
Answer:
Option C
Step-by-step explanation:
Given
Mean= μ=60
and
Standard Deviation= σ=5
In order to calculate the percentage of students between 55 and 65, we have to calculate z-score for both
z-score for 55=(55-60)/5
=(-5)/5
=-1
The area to the left of z-score -1 is 0.1587
z-score for 65=(65-60)/5
=5/5
=1
The area to the left of z-score 1 is 0.8413
Area between z-scores of 55 and 65=0.8413-0.1587
=0.6826
Converting into percentage
=0.6826*100
=68.26%
Option C is the correct answer ..
