Ok, if you say so. Jean took 1/2 hour to complete 3/8 of a math problem.
Answer:
$319.43
Step-by-step explanation:
Monday= 4 * $11.52= $46.08
Tuesday= 4.5 * $11.52= $51.84
Thursday= 7.25 * $11.52= $83.27
Saturday= 12 * $11.52= $138.24
When you add all of those together you get $319.43
hope this helped (:
(this took so long so this better be right...<3)
Answer: The concentration of X is 
and the concentration of Y is 
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes
By solving these two equations, we get that
Hence, the concentration of X is and the concentration of Y is .
Answer:
Step-by-step explanation:
A 36% discount means the selling price is (100-36)% = 64% of the original price.
$272 = 64% of x = 0.64·x
x = $272/0.64 = $425
The area of a trapezoid can be computed as:
A=(b1+b2)h/2, where b1 and b2 ar the bases, h is the height.
With the provided numerical values:
50=(3+7)h/2
50=10h/2=5h
Answer: h=10inches
