I am sure the correct answer is x=0.38629436…hope this help you
Answer:
a. 80 students
b. 92 students
Step-by-step explanation:
Represent arts students with A and Dance students with D.
So, we have,
n(A) = 35
n(D) = 57
Required
Determine n(A or D)
Solving (a):
Here, we have:
n(A and D) = 12
n(A or D) is calculated as thus:
n(A or D) = n(A) + n(D) - n(A and D)
n(A or D) = 35 + 57 - 12
n(A or D) = 80
b. From the given details
n(A and D) = 0 because both students are not mixed up as in (a) above
Using the same formula as (a).
n(A or D) = n(A) + n(D) - n(A and D)
n(A or D) = 35 + 57 - 0
n(A or D) = 92
To multiply fractions, you multiply numerator with numerator and denominator with denominator
In other words: a/b*c/d=(a*c)/(b*d)
So 1st one is (5*2)/(6*3) which is 10/18 or 5/9 simplified
2nd one is (9*5)/(10*18) which is 45/180 or 1/4 simplified
3rd one is (4*3)/(5*4) which is 12/20 or 3/5 simplified
4th one is (2*5)/(3*1) which is 10/3 or 3 1/3 if you want a mixed number
Hope this helped!
135 times because 675 divided by 5 is 135. you would divide the number of her heart beats by the number
Answer:
m<F = 53
Step-by-step explanation:
Exterior angles thm:
5x - 10 + 3x + 14 = 100
8x + 4 = 100
8x = 104
x = 13
m<F:
3x + 14
3(13) + 14
39 + 14
53
