Answers

Answer 1
Answer:

Answer:

Ned will both swim and bicycle at every 24th day.

Step-by-step explanation:

It is given that Ned swim every sixth day and bicycle every eighth day.

For getting the days will he both swim and bicycle. We have to find Least Common Multiple(L.C.M) of 6 and 8.

6 = 2 × 3

8 = 2 × 2 × 2

⇒ LCM of (6 and 8) = 2 × 2 × 2 × 3 = 24

Hence, Ned will both swim and bicycle at every 24th day.
Answer 2
Answer: He will swim and bike on every 24th day. This is because the third 8th and fourth 6th day overlap here. Basically, you have to find the least common multiple.

If y varies directly with x and x=21 and y=14, what is the constant of proportionality?

Answers

Y varies directly with x
y = kx

y=14
x=21

14 = 21k

(14)/(21) = (21k)/(21)
21 and 21 cancels out

(2)/(3) = k

The constant of this proportionality is (2)/(3)

An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length of the lake. What are the dimensions of the lake?

Answers


We know that the area of a rectangle can be written as: length x width

so:

l x (1/5) = 9/20

9/20 x 5/1 = 45/20, which can be reduced to 9/4

So the length is 9/4 miles
