Answer:
The required ratio is 38 : 7
Step-by-step explanation:
Given,
304 calories burned in 56 minutes,
That is, the number of calories burnt in 56 minutes = 304
So, the ratio of the calories burnt and time in minutes = 
∵ HCF(304, 56) = 8,
Thus, the ratio of price of photos and number of photos = 
= 
There would be 12 girls and 18 boys. Since the ratio is 2:3, there are 5 parts total (2+3=5) With 30 students, each part equals 6 students (30/5=6) Therefore the two parts that are girls would be 6 x 2, or 12 students, leaving the remainder of students, 18, to be boys
Yes, it would only be irrational if the numbers had no end, (not repeating like .6666666…)
decimals that end, or repeat the same pattern are rational numbers.
Answer:
RS is about 18.615
Step-by-step explanation:
since XY is the midsegment, it is parallel to the other 2 lines. That also makes the lines proportional
cross multiple
484=26x
x= 18.615
Using algebra...
n and n+2 are the integers
n*(n+2)=288
n^2+2n=288
n^2+2n-288=0
288=2*2*2*2*2*3*3=(2*2*2*2)*(2*3*3)=16*18 and 18-16=2
factor
(n+18)(n-16)=0
n+18=0
n=-18
n+2=-16
this is one solution
n-16=0
n=16
n+2=18
this is another solution
as you can see, it's just a matter of factoring
288
using arithmetic...
√288=16.97≈17
16 and 18 are the integers (as well as -16 and -18)
