$166,245?
A. $11,830
B. $55,415
C. $166,245
D. $498,735

Answers

I think it is c forgive me I f I’m wrong

The amount of budget cut from last year's budget which was $166,245 will be $54860.85 which is nearly  $55,415 from the given option. Hence the correct option is (B).

What is the percentage?

The percentage is the 1 of the hundred or simply the amount or value of any number or data in the range of 100 called percentage.

For example, if Ramesh got 87 marks out of 150 then it required a lot of attention to drawing a conclusion about Ramesh's marks but if I say Ramesh got 58% then it will be easier to think and draw any conclusion.

Given that last year budget was $166,245 and the cut was 33% so it means it will be 0.33 of the $166,245 so

$166,245 × .33 = $54860.85 but in option, it is not mentioned so the nearest answer among the option will be (B).

w weeks.


12 (b) John told Joan that he will have paid her back all of the money, after making

payments for 13 weeks.. Explain why John is incorrect?

Answers

Answer:

P = 80 - 6w

Step-by-step explanation:

Initial amount = $80Payment each week = $6

Required function:

P = 80 - 6w

Time required to pay all money. At this time P = 0

0 = 80 - 6w6w = 80w = 80/6w = 13.33

Since w > 13, John needs 14 weeks

A mixed number to an improper fraction by multiplying the denominator of the fraction by the whole number and then adding the numerator

What are Mixed Numbers?

A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.

To convert a mixed number to an improper fraction , we need to follow these three steps :

Step 1 : Multiply the whole number by the denominator

Step 2 : Add the answer from Step 1 to the numerator

Step 3 : Write answer from Step 2 over the denominator

Take for example :

Let the number be x = 5 5/9

Step 1 :

Multiply the whole number by the denominator

9 × 5 = 45

Step 2 :

Add the answer from Step 1 to the numerator

45 + 5 = 50

Step 3 :

Write answer from Step 2 over the denominator

50/9

Therefore , the mixed number 5 5/9 is converted to its improper fraction as 50/9

Which functions are even? Check all of the boxes that apply.
f(x) = x2 – 3x + 2
7x) = -2)
f(x) = |x|

Answers

Answer:

C) f(x) = |x|

Step-by-step explanation:

Determine if Odd, Even, or Neither

         f (x) = |x|

Find f (−x) by substituting −x for all occurrence of x in f (x). f(−x) = |−x|

Make −x positive.

        f(−x) = |x|

A function is even if  f(−x) = f(x).

Check if  f(−x) = f(x).

        |x| = |x|

Since |x| = |x|, the function is even.
