Are the ratios 7:5 and 11:10 equivalent

Answer:

[tex](f\circ g)(-5)=85[/tex]

Step-by-step explanation:

We are given:

[tex]\displaystyle f(x)=4x+5\text{ and } g(x)=x^2+x[/tex]

And we want to find:

[tex](f\circ g)(-5)[/tex]

This is equivalent to:

[tex]\displaystyle =f(g(-5))[/tex]

So, we will evaluate g(-5) first, which yields:

[tex]\displaystyle g(-5)=(-5)^2+(-5)=25-5=20[/tex]

So:

[tex]=f(g(-5))=f(20)[/tex]

Then:

[tex]\displaystyle f(20)=4(20)+5=80+5=85[/tex]

Therefore:

[tex](f\circ g)(-5)=85[/tex]

Answer:The required time taken by her to read a 400 page book is 13 hours and 20 minutes.

Step-by-step explanation:Given that Lauren took 12 hours to read a 360 page book.

We are to find the time taken by her to read 400 page book at the same rate.

We will be using the UNITARY method to solve the problem.

We have

Time taken by Lauren to read 360 page book = 12 hours.

So, the time taken by Lauren to read 1 page book will be

Therefore, the time taken by Lauren to read a 400 page book is given by

Thus, the required time taken by her to read a 400 page book is 13 hours and 20 minutes.

I would say C

Step-by-step explanation:

I dont know for sure if this is right but it seems like the best answer to me personnaly i would say wait for another user to answer tho to see if they think c to

sooo the answer is: - p -30

4p - 5 (p + 6)

first we distribute:

4p + (-5)(p) +  (-5)(6)

4p + -5p + -30

combine like terms:

(4p + -5p) +( -30)

          -p  +  -30

        =  -p -30

Step-by-step explanation:

Answer:A

Step-by-step explanation:

25 times 3a equals 75a+ 25b when distributed

The expression 75a + 25b can be rewritten by taking 25 commons as 25 (3a + b), so option A is correct.

Mathematical expressions consist of at least two numbers or variables, at least one arithmetic operation, and a statement. A finite combination of symbols that are well-formed in accordance with context-dependent principles is referred to as an expression or mathematical expression.

Given:

75a + 25b = _(a+b)

Factorize the numbers 25 and 75 as shown below,

25 = 5 × 5

75 = 3 × 5 × 5

As you can see that the GCF of the 25 and 75 is 5 × 5 = 25,

Take 25 commons from the expression 75a + 25b as shown below,

25 (3a + b)

Thus, 75a + 25b = 25 (3a + b).

Answer: No, the scenario won't earn you enough money

====================================================

Explanation:

You work 4 hours with your uncle, at $8 an hour, so that means you earn 4*8 = 32 dollars.

You work 12 hours online, at $4 an hour, so you earn 12*4 = 48 dollars.

In total, you earn 32+48 = 80 dollars overall when combining the two lines of work.

The total 80 is smaller than 120, so this scenario isn't possible if you want to aim for $120 or more. You'll need to work more hours somehow.

Answer:

129

Step-by-step explanation:

the answer is 129 because you do 0.50 times 86 which is 43 so you do 43 + 86 which is 129 so $129 is your answer

The selling price of an $86 item after a 50% markup will be $129.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates to one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

The price of an item is $86 and the price is increased by 50%.

Let 'x' be the selling price. Then the selling price is calculated as,

50% = [(x - 86) / 86] x 100

Simplify the equation, then we have

50% = [(x - $86) / $86] x 100

0.50 = (x - $86) / $86

$43 = x - $86

x = $86 + $43

x = $129

The selling cost of a $86 thing after a half markup will be $129.
