The total number of resumes Emily prints = 300

She pays $24.50 for the first hundred resumes. Therefore, number of resumes that remain = 300-100= 200 resumes

\Now she pays a flat rate for each additional 100 resumes.

She pay a total of 48.50 for total of 300 resumes. Since she pays 24.50 for the first 100, the amount the remains = 48.50 =24.50 = $24

Therefore, she pays 24 for 2 sets of 100 resumes

Therefore the flat rate after the first 100 resumes = 24/2 = $12

hope this helps

A farmer was asked how many cows and chickens she has. The farmer replied, "between the cows and the chickens, there are 162 eye
Kazeer [188]
<h2>☀️ <u>Solution</u><u>:</u></h2>

We all know that,

  • All animals have 2 eyes.
  • All cows have 4 feet
  • All hens have 2 feet

So, Let the no. of cows be x and chickens be y

According to question,

  • Total number of eyes = 162

Framing equation,

⇛ Eyes of cows + Eyes of chickens = 162

⇛ 2x + 2y = 162

⇛ 2(x + y) = 162

⇛ x + y = 162/2 = 81 -----------(1)

According to question(Cond.-1)

  • Total number of feet = 270

Framing equation,

⇛ Feet of cows + Feet of chickens = 270

⇛ 4x + 2y = 270

⇛ 2(2x + y) = 270

⇛ 2x + y = 135 ----------(2)

Subtracting eq.(1) from eq.(2),

⇛ 2x + y - (x + y) = 135 - 81

⇛ 2x + y - x - y = 54

⇛ x = 54

Putting value of x in eq.(1),

⇛ 54 + y = 81

⇛ y = 81 - 54

⇛ y = 27

⚘ So, Total number of animals,

  • Number of cows = x = 54
  • Number of chickens = y = 27

Hence, solved !!

An urn contains 10 marbles: 4 red, 3 white, 2 blue, and 1 orange. (4 points) (a) What is the probability of drawing a marble tha
photoshop1234 [79]

Answer:

a) 0.70

b) 0.30

c) 12/45 =4/15

d) 2/45

Step-by-step explanation:

a) Prob of drawing a marble red or white = No of red and white marbles/total marbles

= 7/10 = 0.70

b)  Prob of drawing a marble neither red nor white = 1-7/10 = 0.30

c)  Prob of drawing two marble one red and one  white at the same time

= \frac{4C1 (3C1}{10C2 } =\frac{12}{45}

d) Prob of drawing two marble one blue and orange  white at the same time

= \frac{2C1 (1C1}{10C2 } =\frac{2}{45}

If (fog)(x)=7x-1/3 and f(x)=3x+5,find g(x),where g(x)is linear<br>​
Svetach [21]

Answer: g(x) = \dfrac73x-\dfrac{16}{9}

Step-by-step explanation:

Given: (fog)(x)=7x-\dfrac13

f(x)=3x+5

and g(x) is linear.

A linear function is of the form : y= mx+c

Let g(x)= mx+c

Then, (fog)(x)=f(g(x))= f(mx+c)

= 3(mx+c)+5\\\\=3mx+3c+5

Comparing it with the original (fog)(x), we get

3mx+3c+5=7x-\dfrac{1}{3}

Comparing coefficient of x and constants separately

3m=7,\ \ \ \ 3c+5=-\dfrac13\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ 3c =-\dfrac{1}{3}-5\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ 3c =-\dfrac{16}{3}\\\\\Rightarrow\ m=\dfrac{7}{3},\ \ \ \ c =-\dfrac{16}{9}

So, g(x) = \dfrac73x-\dfrac{16}{9}
