Answer: 16
Step-by-step explanation:
100% is 64 and 1% of 64 is 6.4 and if you multiply 6.4 times 25 is 160 so 125% is 160 so 90% of 160 is 144 so 160-144 is 16
Answer:
13 yds * 32 yds
Step-by-step explanation:
A=area, l=length, w=width
A=w*l
l=6+2w
A=w*(6+2w)
A=6w+2w^2
416=6w+2w^2
416/2=(6w+2w^2)/2
208=3w+w^2
208-208=3w+w^2-208
w^2+3w-208=0
w^2+16w-13w-208=0
w(w+16)-13(w+16)=0
(w-13)(w+16)=0 ==> w+16=0 ==> w=-16, w can't be negative.
w-13=0
<u>w=13</u>
l=6+2w
l=6+2(13)
l=6+26
<u>l=32</u>
Dimensions: 13 * 32
Let use h= hotdogs price and c=chips price
we know that
4h +4c= 17
5h+3c=17.75
t use the elimination method we will multiply the first equation by 5 and the second one by (-4)
20h +20c=85
-20h -12c= -71
8c=14, we will divide by 8 both side and c=1.75, so a bag of potato chips cost $ 1.75
now we will substitute the c in the first equation
4h+7=17 therefore 4h=17-7, 4h=10, h=2.50
a bag of potato chips is 1.75
a hot dog costs 2.50
Answer:
The probability that Aaron goes to the gym on exactly one of the two days is 0.74
Step-by-step explanation:
Let P(Aaron goes to the gym on exactly one of the two days) be the probability that Aaron goes to the gym on exactly one of the two days.
Then
P(Aaron goes to the gym on exactly one of the two days) =
P(Aaron goes to the gym on Saturday and doesn't go on Sunday) +
P(Aaron doesn't go to the gym on Saturday and goes on Sunday)
- If Aaron goes to the gym on Saturday the probability that he goes on Sunday is 0.3. Then If Aaron goes to the gym on Saturday the probability that he does not go on Sunday is 1-0.3 =0.7
- Since the probability that Aaron goes to the gym on Saturday is 0.8,
P(Aaron goes to the gym on Saturday and doesn't go on Sunday) =
P(the probability that Aaron goes to the gym on Saturday)×P(If Aaron goes to the gym on Saturday the probability that he does not go on Sunday)
=0.8×0.7=0.56
- The probability that Aaron doesn't go to the gym on Saturday is 1-0.8=0.2
- And if Aaron does not go to the gym on Saturday the probability he goes on Sunday is 0.9.
Thus, P(Aaron doesn't go to the gym on Saturday and goes on Sunday) = P(The probability that Aaron doesn't go to the gym on Saturday)×P(if Aaron does not go to the gym on Saturday the probability he goes on Sunday)
=0.2×0.9=0.18
Then
P(Aaron goes to the gym on exactly one of the two days) =0.56 + 0.18 =0.74
Answer:
The price of the sweater originally was $40.
After reducing it $6, it is now $34.
Step-by-step explanation:
15% = .15
0.15x = 6
x = $40 -- this is the original price of the sweater.
$6 discount due to damage
$40 - $6 = $34
