Answer:
You will not be able to find the area of the framed painting without finding the length, which you did not provide. Assuming you meant “3 inches wide” to actually mean the length then the surface area of the painting is 9 inches squared. However, to find the height, you must divide 3 by 2.5 as the width was said to be 2.5 times the height of the painting. This will give you an answer of 1.2 inches in height.
Answer:
t = 24
Step-by-step explanation:
Given that t varies inversely with a then the equation relating them is
t = 
← k is the constant of variation
To find k use the condition t = 2 when a = 36, that is
2 = 
( multiply both sides by 36 )
72 = k
t = 
← equation of variation
Given a = 3, then
t = 
= 24
Answer:
35
Step-by-step explanation:
15 plus 10 equals 25.
25 plus 10 equals 35.

Answer: 0.4667
Step-by-step explanation:
According to 68–95–99.7 rule , About 99.7% of all data values lies with in 3 standard deviations from population mean (
).
Here , margin of error = 3s , where s is standard deviation.
As per given , we have want our sample mean 
to estimate μ μ with an error of no more than 1.4 point in either direction.
If 99.7% of all samples give an within 1.4 , it means that
Divide boths ides by 3 , we get
Hence, So must have 0.4667 as standard deviation so that 99.7 % 99.7% of all samples give an within 1.4 point of μ .
A=p (1+I/k^kn
A future value ?
P principle 3700
i interest rate 0.0184
K compounded quarterly 4
N time 6 years
A=3,700×(1+0.0184÷4)^(4×6)
A=4,130.84
Interest earned=A-p
4,130.84−3,700=430.84
Hope it helps:-)
