Answer:
B
Step-by-step explanation:
11
(9, 18, 27, 36, 45, 54, 63, 72, 81, 90 and 99)
Those numbers divisible by 9 are the multiple of 9; thus need to know how many multiples of 9 there are between 1 and 100:
100 ÷ 9 = 11 r 1 ÷ last multiple of 9 is 11 × 9 (= 99)
→ There are 11 - 1 + 1 = 11 numbers between 1 and 100 which are divisible by 9.
(They are 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99.)
Answer:
the answer is B because 3x4 is 12
Hello from MrBillDoesMath!
Answer: 9/25
Discussion:
My first observation is that both 36 and 100 are even numbers, so let's divide each by 2.
36/100 = 18/50
Again, 18 and 50 are even numbers so let's divided each by 2
= 18/50 = 9/25
While I didn't write it out, my statement "divide them by 2" is really this:
36/100 = ( 36/2) / (100/2) = (18) /50 = ( 18/2) / (50/2) = 9/25
Confusing, isn't it!
A shorter, but equivalent, approach is to divide the numerator and denominator by 4.
Regards, MrB.
If the two angles form a linear pair, the sum of the angles is 180 degrees.
If the small angle is one-third of the other, then the total is 1+1/3=4/3 of the larger angle.
By proportion,
L+L/3=4L/3=180
L=180*3/4=135 degrees
Smaller angle = L/3=45 degrees
Check: L+L/3=135+45=180 degrees, ok
