the two ratios are equivalent beacuse 4/6 is not like a positive number so 4/6 and 14/21 are equivalent
If x people were surveyed then 42% *x=210
210/42%=500=x
Therefore, 500 people were surveyed
Answer:
Once.
Step-by-step explanation:
To find when they chirp together, we must find the LCM of the two numbers. The LCM, or least common multiple of 13 and 5 is 65. Therefore, after 65 minutes is the first time they chirp together. Then we can multiply 65 by 2 to see if they chirp a second time. 65x2 is 130, but 8AM-10AM is only 120 minutes, therefore they do not chirp together more than 1 time.
Answer:
26 ft.
Step-by-step explanation:
1) First I would suggest swapping 8 and 2/3 from a mixed number into a fraction:
8 2/3=8+2/3=(24/3)+(2/3)=26/3
2) Next you just need to multiply the number of shelves John wants to make by the required amount of lumber. He wants to make 3 shelves and each one requires 8 2/3 ft. of lumber, which(as we found above) is 26/3 ft. of lumber:
3×(26/3)=26
So John will need 26 ft. of lumber for his shelving.

Answer:
1414 cm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
For a radius of 5 cm and a height of 8 cm, the volume is ...
V = π(5 cm)²(18 cm) = 450π cm³ ≈ 1414 cm³
The volume of Nadia's sugar container is about 1414 cm³.

<em>Additional comment</em>
The value will be 1413 cm³ if you use 3.14 for π.
