in 12 key 5 black keys are appearing so consider x key will appear in 120 keys
120/x = 12/5
solving further,
x= 50
Answer - If the pattern shown continues, 50 black keys appear on a pipe organ with a total of 120 keys!
Answer:
4:!
Step-by-step explanation:
4:1 because their are 4 boys for every 1 girl
66.67%
It is this because
To find percentage, we need to find an equivalent number with denominator 100. Multiply both numerator & denominator by 100
56
84
×
100
100
= (
56 × 100
84
) ×
1
100
= 66.67
100
Therefore, the answer is 66.67%
If you are using a calculator, simply enter 56÷84×100 which will give you 66.67 as the answer.
Answer:
question is 2x^2+5x^2-5X^3 if the value of x=2 then we put the value of x in equation= 2(2)^2+5(2)^2-5(2)^3 =2*4+5*4-5*8 = 8+20-40 =28-40 =-12 ans
L = 2w + 4 , l + w = 80
solve using subsitiution.
(2w + 4) + w = 80
simplify / combine common
3w + 4 = 80
subtract 4 from both sides
3w = 76
divide by 3
w = 25 1/3 in
80 - 25 1/3 = 54 2/3
is it true that 54 and 2/3 inches is 4 inches more than two times 25 1/3? Yes.
Length = 54 and 2/3 inches
W = 25 and 1/3 inches
hope this helps ;D
