1/2 times 8 equals 4.
You multiply by 8 because the denominator is 8 so you have to have that recipe 8 times to get a whole.
Answer:
x = 2.
Step-by-step explanation:
The corresponding sides are in the same ratio (because they are similar).
So 5x / 5 = 4 /x
5x^2 = 20
x^2 = 4
x = 2.
Answer:
0.8 or 4/5 foot long each
Step-by-step explanation:
3 1/5 as a decimal is 3.2
3.2÷4=0.8
or 4/5
Answer:
B
Step-by-step explanation:
Answer:
b. Every 24 minutes
Step-by-step explanation:
A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.
The first step is to:
Find and list multiples of each time each neon sign blinks.
This means, we find the Multiples of 6 and 8
Multiples of 6:
6, 12, 18, 24, 30, 36
Multiples of 8:
8, 16, 24, 32, 40
The first and common multiple of 6 and 8.
Therefore, the Least common multiple [LCM(6, 8) ] = 24
Hence, they often blink at the same time every 24 minutes.
Therefore, option b.Every 24 minutes is correct.
