Daisy made 6 phone calls in 13 hour. At that rate, how many phone calls can she make in 1 hour?

She can make almost 1 phone call in an hour (particularly, 46 minutes of call per hour)

Step-by-step explanation:

This problem can be solved by using ratios and proportions.

Step 1: Identify the "knowns" from the "unknown."

It is known that Daisy can make 6 phone calls in 13 hours. Now, the problem is asking for the number of phone calls Daisy can make in 1 hour.

The "unknown" here is the number of phone calls Daisy can make in 1 hour.

Step 2: The values should be plug into the proportion.

              =

Step 3: We can now solve the proportion.

= ⇒x = 0.46 calls per hour (almost 1 call per hour)

just pick what you think i need more time let me know if this

step-by-step explanation:

delaney would like to make a 5lb nut 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.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
