Answer: f(x) = -3 if -4 ≤ x ≤ -1

Explanation: The filled in circles mean that solution is possible, so you use the equal to sign.

Hope this helps!

You have 1 case of soap bars and there are 150 bars in a case. You use 300 bars of soap per day. How many cases do you need to o

diamong [38]

<span><u><em>Answer:</em></u>
14 cases

<u><em>Explanation:</em></u>
<u>First, we will need to find the number of cases needed per day:</u>
We know that one case includes 150 bars and that the daily consumption is 300 bars. To know the number of cases needed daily, we will use cross multiplication as follows:
1 case .............> 150 bars
?? cases .........> 300 bars
number of cases needed daily = </span> $\frac{300*1}{150}$ <span>
number of cases needed daily = 2 cases

<u>Then, we will get the number of cases needed weekly (7 days):</u>
We know that 2 cases are needed daily. To know the number of cases needed weekly (7 days), we will simply use cross multiplication as follows:
1 day .............> 2 cases
7 days ...........> ?? cases
number of cases needed weekly = </span> $\frac{7*2}{1}$ <span>
number of cases needed weekly = 14 cases

Hope this helps :)</span>

RU is a diameter, so the two equations make half a circle which is 180 degrees.

24x+5 + 10x+5 = 180

Combine like terms:

34x + 10 = 180

Subtract 10 from both sides:

34x = 170

Divide both sides by 34

X= 5

RS= UV

RS = 10x +5

Replace x with 5

RS = 10(5) + 5 = 55

Answers:

X = 5

RS = 55

Elementary and secondary schools were classified by the number of computers they had.

Keith_Richards [23]

Answer:

$Probability = 0.7259$

$Probability = 0.2741$

$Probability = 0.4414$

Step-by-step explanation:

Given

The table

First, we calculate the amount of schools

$Total = 752 + 3352 + 18865 + 14016 + 46805$

$Total = 83790$

Solving (a): Probability of 75+ computers.

From the given table, schools with 75 or more computers have the population of:

$75\ or\ more = 14016 + 46805$

$75\ or\ more = 60821$

The probability is calculated as:

$Probability = \frac{75\ or\ more}{Total}$

$Probability = \frac{60821}{83790}$

$Probability = 0.7259$

Solving (b): Probability of less than 75 computers.

From the given table, schools with less than 75 computers have the population of:

$Less\ than\ 75 = 752 + 3352 +18865$

$Less\ than\ 75 = 22969$

The probability is calculated as:

$Probability = \frac{Less\ than\ 75}{Total}$

$Probability = \frac{22969}{83790}$

$Probability = 0.2741$

Solving (c): Probability of less than 10 computers.

From the given table, schools with less than 100 computers have the population of:

$Less\ than\ 100 = 752 + 3352 +18865+14016$

$Less\ than\ 100 = 36985$

The probability is calculated as:

$Probability = \frac{Less\ than\ 100}{Total}$

$Probability = \frac{36985}{83790}$

$Probability = 0.4414$

It takes Amir 30 minutes to walk to work. If he drives, it takes him 1/3 of that time. What is the latest time that Amir can lea

UkoKoshka [18]

8:50 am

1/3 of 30 = 10 min (so it takes 10 min for him to drive to work)

9:00-10min = 8:50
