Answer:

T=25d+\frac{3}{4}n+5c

Step-by-step explanation:

A student earns a day to deliverer a newspaper= $25

She delivers for d days .

So she earns in d days = $25d

She also earns extra charges for each newspaper = $0.75 = \frac{3}{4}

If she delivers n newspapers .

So. she earns extra charges for n newspapers = \frac{3}{4} n

Now we are also given that She earns $5 for each new customer .

If she has c new customers .

So, she earns for c customers = $5c

So, her total earning = 25d+\frac{3}{4}n+5c

Let T denotes the total earning .

So,  T=25d+\frac{3}{4}n+5c

Thus Option 2 is correct.

Noah drew 26 hearts, 21 stars, and 38 circles. what is the ratio of stars to hearts to circles?
mamaluj [8]

Answer:

21:26:38

Ratio in mathematics is the relationship between two or more amounts, showing how many times they can be contained in one another.

Example: 1:2 means there are two times the first amount in the second.

For the case above;

Given;

Number of each shape noah drew;

hearts = 26

Stars = 21

circles = 38

The ratio of stars to hearts to circles

N(stars) : N(hearts) : N(circles)

21:26:38

Since they are not divisible by a common factor the ratio remains;

Which pair of numbers is relatively prime?
Evgen [1.6K]

Answer:

<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Step-by-step Explanation:

<u>Answer - A</u>

<u />

Two numbers are relatively prime if they have no common factors (aside from 1). So lets solve for the factors of the number to see if they are relatively prime...

A. Relatively Prime 

26=1,2,13,26

99=1,3,9,11,33,99

B. NOT RELATIVELY PRIME

90=1,2,3,5,6,9,10,15,18,30,45,90

117=1,3,9,13,39,117

C. NOT RELATIVELY PRIME

100=1,2,4,5,10,20,25,50,100

202=1,2,101,202

D. NOT RELATIVELY PRIME

201=1,3,67,201

444=1,2,3,4,6,12,37,74,111,148,222,444
