Answer:

Crew: 32

Marty: 48

Blakely: 24

Step-by-step explanation:

I mainly just used guess and check. Crew is 32 years old. So, let's find Marty's age.

32 × 1. 5 = 48

Marty is 48. Now, let's find Blakely's age.

32 × 0.75 = 24

Add all the ages together.

32 + 48 + 24 = 104

Hope that helps.

HURRY!!! I WILL GIVE BRAINLIEST FOR CORRECT ANSWER
Sergeeva-Olga [200]

Answer:

A function is a relation in which each element of the domain, or x-value, is mapped to one element of the range, or y-value.

The question we are asked is if cost is a function of the activity type.  This means that cost would be the range and activity type would be the domain.

If this is a function, then each activity type would have only one cost.  However, on different days of the week each activity type has different prices; this means there is more than one cost for each activity type, and it is not a function.

A transformer increases the input voltage from 12V to 12,000V. What is the ratio of the number of wire turns on the primary coil
erma4kov [3.2K]

Answer:

\frac{n_p}{n_s}=\frac{1}{1000}

Step-by-step explanation:

Given voltage of primary coil is V_p=12V

And voltage of secondary coil is V_s=12,000V

A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil (n_p) and secondary coil (n_s).

Following equation represents the relation between them.

\frac{V_s}{V_p} =\frac{n_s}{n_p}\\\\\frac{12,000}{12}=\frac{n_s}{n_p}\\\\1000=\frac{n_s}{n_p}

Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is

\frac{n_p}{n_s}=\frac{1}{1000}

What is the slope of the line represented by the table below?
gayaneshka [121]
9/5

If you choose two points you can find the equation change in y/change in x (y2-y1)/(x2-x1). Using the first two points this looks like:

(49-22)/(25-10)=27/15=9/5
