Answer:
The one of (L,b)= (5m, 10m) is the only correct answer.
Step-by-step explanation:
P= 2(L+b)
A= L×b
make b subject of formula in area we have;
b= A/L
in perimeter; p= 2(L +(A/L))
p= (L²+A)/L
pL= L²+A
L²-pL+A= 0
L²-30L+50=0
L²-25L-5L+50=0
L(L-25)-5(L-25)=0
(L-5)(L-25)= 0
L= 5 or 25m
substitute in A
50= 5b or 50= 25b
b= 10 or 2m
Answer:
The answer is "option C".
Step-by-step explanation:
Distinctions are also the mean squared variance just are calculated as the number of standard differences divided by "N" and for a population. After all, if a sample uses this very same definition.
- Its standard deviation would become partially skewed as well as the resulting community value becomes continuously underestimate.
- Its experimented formula consequently includes a correction modification for a bias. Its modification involves dividing by instead of n.
The value of the investment is multiplied by (1+.05/4) = 1.0125 each quarter. After 36 quarters, the value is 1.0125³⁶ ≈ 1.563944 times its original value.
$7650×1.563944 ≈ $11,964.17 . . . . value after 9 years
Answer:
D. 2 1/4

0.25 = 1/4
2.25 = 2 1/4
