If point B is halfway between 0 and 1 on a number line and point A is halfway between 0 and point B, what fraction of 1 does point A represent?

Answers

So B is halfway between 0 and 1. What's half of 1? 1/2.

A is halfway between 0 and B. What's half of 1/2? 1/4.

So A is 1/4 of 1.

Alternatively -

0 - A - B - - - 1

If each - is an eighth, A is at 2/8, or 1/4

Answer:

So B is halfway between 0 and 1. What's half of 1? 1/2.

A is halfway between 0 and B. What's half of 1/2? 1/4.

So A is 1/4 of 1.

Alternatively -

0 - A - B - - - 1

If each - is an eighth, A is at 2/8, or 1/4

A set of house plans is made in the ratio 25 : 1. If a room is 5 m long, how long is this room on the plan?

Answers

Answer:

0.2 on the plan

Step-by-step explanation:

The unit is not given, so whatever the unit is will follow. I'm going to say that it is in meters.

25 meters in real life=1 inch (just a guess) on the plan.

25÷5 (the room length given) = 5

1÷5=0.2

You divide them both by the same number so your ratio can have the same rate. Hope this helps.

Delaney would like to make a 5lb mixture that is 60% peanuts and 40% almonds. She has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds. Let p represent the number of pounds of peanuts needed to make the new mixture,and let m represent the number of pounds of the 80% almond-20% peanut mixture.(a) What is the system that models this situation?
(b) How many pounds of peanuts and how many pounds of the 80% almond-20% peanut mixture will she need?

Answers

This is a mixture problem. Let's call the mixture of

20%peanuts - 80% almonds as mixture A

Let's call the

100% peanuts as mixture B

and the

60% peanuts - 40% almonds as mixture C

Since we get mixture C by adding mixture A and B together, we know that the amount in pounds of mixture A and mixture B is 5 pounds.

Hence we

let m be the amount in pounds of 20%peanuts-80% almonds mixture, or mixture A

and

50-m be the amount in pounds of mixture B

So, the system of equations that models this situation is:

0.20m + 1(50-m) = 0.60(5)
0.80m + 0(50-m) = 0.40(5)

Solving for m using equation 2 gives us

m = 2.5 lb.

That means it will take 2.5 lb of mixture A (20%peanuts-80%almonds) and 2.5 lb of mixture B (100%peanuts) to form 5 lb of mixture C (60%peanuts-40%almonds).

at 3:00 am, the temperature was -13 degrees. in alaska. At 10:00 am, the temperature was 22 degrees, what was the average change in temperature per hour?

Answers

If you go from -13 to 0, you have an increase of 13 degrees. Then if you go from 0 to 22 you have an increase of 22 degrees. 13 + 22 = 35.
3:00 am to 10:00 am is 7 hours so:
35 degrees/7 hours = 5 degrees/hour
Also english is my second langauge so sorry if it's hard to understand

So, there is a 7 hour span. There is 35 degree change total. So solve. Take 37/7=5
5 is the average
