Answer:

not enough information

Step-by-step explanation:

Perpendicular lines intersect at right angles. Since lines c and b are perpendicular, angles 1, 2, 3, and 4 are right angles, and each one measures 90 degrees.

Angle 2 is formed by the intersection of lines a and b. We are not told anything about the intersection of lines a and b, and we are not told anything about the relationship between lines a and c, so we do not have enough information to determine the measure of angle 2.

Laurie says summer is 1 over 4 of the year. Maria says summer is 3 over 12 of the year. Who is correct? explain
nasty-shy [4]

Answer:


Step-by-ste

Oh, oh! This is such a tricky question...

Guess what!

Both of them are correct. Why?

Because if we simplify 3/12, we get 1/4th!

(How do you simplify?)

3/12 = 1/4

Because if we divide both "3" and "12" in 3/12 by 3, we get 1 instead of 3 and 4 instead of 12.


I hope you've got it! ;)

The ratio (by volume) of salt and sugar in a certain mixture is 4 to 8. If the total volume of the solution is 300 cubic feet, w
Tatiana [17]
You will use the ratio 4:8 to create a part to part to whole ratio.

First simplify 4:8 to 1:2, then make it 1:2:3 (Salt:Sugar:Total).

Use this to find the volume of sugar.  2 sugars for every 3 total would be equivalent to 200 cubic feet of sugar for every 300 total cubic feet.
