Raoul has to finish of 473-Page book in a week he decided to read the same number of pages each weekday and 30 extra pages on Sa

kolezko [41]

Answer: he read 59 pages on Wednesday

Step-by-step explanation:

Total number of pages in the book is 473 and Raoul has to finish in a week.

The total number of days in a week is 7.

Let x represent the number of pages that he read I'm each day of the week. He decided to read 30 extra pages on Saturday and on Sunday. This means that sum of pages that he read on Saturday is

x + 30 and sum of pages that he read on Saturday is x + 30.

Total number of pages that he read on each of the other five days is 5x

Total number of pages read in the week would be

5x + x + 30 + x + 30 = 7x + 60

Therefore

7x + 60 = 473

7x = 473 - 60 = 413

x = 413/7 = 59

Help pls need help show your solution and then graph

Stella [2.4K]

Answer:

Step-by-step explanation:

We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.

ax^2 + bx + c

a=4

b=-9

c=2

you can try it by hand or use this:

https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)

so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

A political analyst conducted an observational study in 2014 that measured the rate of voter dissatisfaction with the United Sta

Ilia_Sergeevich [38]

Based on the results of the study, the conclusion which is valid is There is correlation between the increase in the rate of televised political attack ads since the previous congressional election and the rate of voter dissatisfaction in the observed districts.

<h3>What does the study conclude?</h3>

The study showed that the rate of voter dissatisfaction in the districts since the previous election cycles is similar to the rate of increase of televised political attack ads.

The fact that both the rate of voter dissatisfaction and televised political attack ads moved together means that they correlate with each other.

It is important to note however, that correlation does not equate causation so there might be no link between the two rates.

Which of the following represents the additive inverse of 125? A. -(-125) B. 125 C. -125 D. 1/25

Elden [556K]

Additive inverse of 125 is – 125, option C is correct.

Solution:

Given that , a number is 125

We have to find the additive inverse for the above given number from the above given set of options.

Now, we know that, sum of a number and its additive inverse equals to 0.

So, let us check option by option.

Option A:

Given number is -(-125)

-(-125) ⇒ 125 + ( - ( - 125 ) )

⇒ 125 + 125

⇒ 250 ⇒ wrong option

Option B:

Given number is 125

⇒ 125 + 125 ⇒ 250 ⇒ wrong option

Option C:

Given number is -125

125 + ( - 125 ) ⇒ 125 – 125 ⇒ 0 ⇒ correct option

Hence, additive inverse of 125 is – 125, option C is correct
