Winning%=100[wins/(total games)]
w%=100(A-B)/A
So the way that your choice expressed that is:
(A-B)/A x 100
Answer:
side of 6.124 ft and height of 3.674 ft
Step-by-step explanation:
Let's s be the side of the square base and h be the height of the rectangular box.
The base and the roof would have an area of 
and cost of
The sides would have an area of 4sh and cost of 4sh*2.5 = 10sh
So the total cost for the material is
The volume of the shed has the following formula
To find the maximum value for V, we can take its first derivative, and set it to 0
h = 45/s - 0.6s = 3.674 ft
Answer:
(5a−3)^2
Step-by-step explanation:
25a^2 - 30a + 9
Factor the expression by grouping. First, the expression needs to be rewritten as 25a^2+pa+qa+9. To find p and q, set up a system to be solved.
p+q=−30
pq=25×9=225
Since pq is positive, p and q have the same sign. Since p+q is negative, p and q are both negative. List all such integer pairs that give product 225.
−1,−225
−3,−75
−5,−45
−9,−25
−15,−15
Calculate the sum for each pair.
−1−225=−226
−3−75=−78
−5−45=−50
−9−25=−34
−15−15=−30
The solution is the pair that gives sum −30.
p=−15
q=−15
Rewrite 25a^2 - 30a + 9 as (25a^2−15a)+(−15a+9).
(25a^2−15a)+(−15a+9)
Factor out 5a in the first and −3 in the second group.
5a(5a−3)−3(5a−3)
Factor out common term 5a−3 by using distributive property.
(5a−3)(5a−3)
Rewrite as a binomial square.
(5a−3)^2
Simple, to find the percentage you scored on your test, take
What you got= 69
Total=75
Divide,
69/75=0.92
Finally, multiply by 100.
0.92*100=92
<span>You got a 92% on the math test.</span>
