Answer:
-14/25
Step-by-step explanation:
-4/5 * 7/10
Multiply the numerators
-4*7 = -28
Multiply the denominators
5*10 = 50
numerator/ denominator
-28/50
Divide top and bottom by 2
-14/25
Answer:
Number is two
Step-by-step explanation:
First of all we find the closest factors of 864 which are 32 x 27
Simply them we have
32 x 27 = 2^5 x 3³
So
Next we know that to be aperfect cube, each exponent needs to be equally divided by divisible by 3.
So If we multiply 864 x 2 we get
Then
1728 = 2^6 x 3³
So if we finally
Take the cube root of that is 2²* 3^1 = 4 x 3= 12
So 2² x 3^1
So if we equate the powers we have the answer as 2.
I can't see the whole question and which one do you need?
7/10 is 70%
70% of 120 is 84.
So 84 people would prefer to practice after school.
It should be -
x = 53
y = 90
w = 53
z = 37
