Answer:
Step-by-step explanation:
Alright, lets get started.
We first assume that Alfonso's bicycling speed with no wind is = x miles per hour
With the wind, his speed will be = miles per hour
Against the wind, his speed will be = miles per hour
For traveling 54 miles with the wind, the time will be =
For traveling 30 miles against the wind, the time will be =
Alfonso found that both the timings are same, so
Cross multiplying
Solving for x
Dividing 24 in both sides
So, Alfonso's normal bicycling speed with no wind is 14 miles per hours. : Answer
Hope it will help :)
Which grade is this and which school?
I = P x R x T
I = 16000 x .222 x 1
I = $3552
The yearly earnings would be $3552
Answer:
-3
Step-by-step explanation:
Let the first term be a-d, second term be a and third term be a+d
d is the common difference
If each term, starting with the 3rd term, is found by multiplying the previous two terms then:
a(a-d) = a+d
a²+ad-a-d = 0
a(a+d)-1(a+d) = 0
(a+d)(a-1) = 0
a-1 = 0
a= 1
a+d = 0
1+d = 0
d = 0-1
d = -1
Get the sixth term
nth term of a sequence is expressed as
Tn = a+(n-1)d
T6 = 1+(6-1)(-1)
T6 = 1+5(-1)
T6 = 1-5
T6 = -4
Get the third term T3
T3 = a+2d
T3 = 1+2(-1)
T3 = 1-2
T3 = -1
difference between the 6th and 3rd terms in the sequence is expressed as;
Difference = T6-T3
Difference = -4-(-1)
Difference = -4+1
Difference = -3
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
