Kali just started a new sales floor job to save for college. She earns 15.75 plus a flat fee of 50 . She wants to earn between 200 and 400 . The following inequality represents her earning potential
200 ≤ 15.75x + 50 ≤ 400 Solve the inequality PLEASE HELP ASAP
!!
Solving the inequality the range of x becomes 9.523 ≤ x ≤ 22.222.
The given inequality which needs to be solved is 200 ≤ 15.75x + 50 ≤ 400.
If 50 is subtracted from each part or side of the inequality we get,
200 - 50 ≤ 15.75x + 50 - 50 ≤ 400 -50 which will be equal to,
150 ≤ 15.75x ≤ 350, now to solve this inequality divide the given inequality with the coefficient of x which is 15.75 to get the range of x.
Hence the inequality becomes 150÷15.75 ≤ 15.75x÷15.75 ≤ 350÷15.75. solving this equation the value of x becomes 9.523 ≤ x ≤ 22.222.
So the range of inequality that represents Kalis earning potential ranges from (9.523,22.222) for the given question.

f(m) = (x + 1)(x - 5)| has two solutions. What is the set of values for f(m)? How would you describe the locations of values in this solution set?
Answer:
x = {x: -1, 5}
Step-by-step explanation:
[tex]{ \rm{f(m) = (x + 1)(x - 5)}}[/tex]
- To find the values of function f(m), we consider its zero or its root by letting f(m) = 0
[tex]{ \rm{f(m) = 0 = (x + 1)(x - 5)}} \\ { \rm{(x + 1)(x - 5) = 0 \: \: \: \: \: \: \: \: \: \: \: \: \: }}[/tex]
- Either (x + 1) or (x - 5) is equated to zero
For (x + 1);[tex]{ \rm{x + 1 = 0}} \\ { \rm{x = - 1}}[/tex]
For (x - 5);[tex]{ \rm{x - 5 = 0}} \\ { \rm{x = 5}}[/tex]

subtract 74 from both sides
-8w=-52
divide both sides by -8
w=6.5
Answer:
-8w=22-74

A battery is charged. The percentage of the battery's capacity that is charged as a function of time (in minutes) is graphed 50+ 70 50+ Capacity charge 20+ 10 What was the battery's charging level when the charging began? 12
The equation of the line (segment) is:
[tex]y=2x+40[/tex]Where y is the percentage of the charge, and x is the time (in minutes) that has passed since the charge started.
How do we know that? Because we can identify two points in the graph shown in the image:
[tex](0,40),(5,50)[/tex]
Notice that the line intersects the y-axis in point 40 (when the battery had 40% of its charge)
You can easily see that the equation I first wrote is correct by simply substituting the values of those two points I just wrote above.
Since we need 'the battery's charging level when the charging began', we need to set x=0, as we need the value of y (percentage of the charge) when the charging started.
So, if x=, then:
[tex]y=2\cdot0+40=40[/tex]Therefore, the answer is 40%

Let us first solve the triangle on the right side involving angle x.
Recall that the sum of angles in a triangle must be equal to 180°.
So we can write
[tex]\begin{gathered} 41+78+x=180 \\ 119+x=180 \\ x=180-119 \\ x=61\degree \end{gathered}[/tex]Therefore, the angle x is equal to 61°
Now let us solve the triangle involving angle S and T.
Again applying the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} 48+57+S=180 \\ 105+S=180 \\ S=180-105 \\ S=75\degree \end{gathered}[/tex]As you can see, the angle S and T form a straight line angle.
Recall that a straight line angle is equal to 180°
[tex]\begin{gathered} S+T=180 \\ 75+T=180 \\ T=180-75 \\ T=105\degree \end{gathered}[/tex]Therefore, angle S = 75° and angle T = 105°
Now let us solve the remaining figure.
On the right side of the figure, apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} A+42+40=180 \\ A+82=180 \\ A=180-82 \\ A=98\degree \end{gathered}[/tex]As you can see, the angles A and B are opposite angles.
We know that opposite angles are equal.
[tex]\angle A=\angle B=98\degree[/tex]Now we know the angle B so let us apply the property that the sum of angles in a triangle must be equal to 180°
[tex]\begin{gathered} B+48+C=180 \\ 98+48+C=180 \\ 146+C=180 \\ C=180-146 \\ C=34\degree \end{gathered}[/tex]Therefore, angle A = 98° and angle B = 98° and angle C = 34°

1. A sum of money is to be shared among three friends Paul, Mark and Anna in the ratio 2: 3: 5 respectively. If Paul received $ 48,000. Determine
a. Anna’s Share
b. Mark’s share.
c. The total sum
a)Sum of money share by Anna is $120000
b)Sum of money share by Mark is $72000
c) The total sum the three friends have is $ 240000
The ratio of the amount of money shared among three friends is 2: 3: 5.
Let's take the common factor to be x.
Sum of money Paul has = 2x
Sum of money Mark has = 3x
Sum of money Anna has = 5x
It is given that Paul receive $48000
So,
2x = 48000
x = 24000
a) Anna's share = 5x
= 5× 24000
= $120000
b) Mark's share = 3x
= 3 × 24000
= $72000
c) The total share = 2x + 3x + 5x
= 10x
= 10 × 24000
= $240000
Therefore the sum of money share by Anna is $120000, Mark is $72000 and the total sum of money is $240000.

In this kind of question, we always need to know what is the equivalence between two measures:
We already know that in 1 centimeter there are 10 millimeters. With this equivalence, we can write:
740.2 millimeters * ( 1 centimeter / 10 millimeters )
When we have a unit in the numerator and also in the denominator, like millimeters, in this case, both units are converted in 1, and they do not need to be in the final answer (millimeters/millimeters = 1). Therefore:
740.2 * ( 1 centimeter / 10 ) =
( 740.2 / 10 ) centimeter =
When we divide a number by 10, 100, 1000, we write the decimal point to the left as many zeros have the 10, 100, 1000. In this case, we only have one zero.
Thus, we write the decimal part one digit to the left:
( 740.2 / 10 ) centimeter =
74.02 centimeter (this is the answer).
Therefore, there are 74.02 centimeters in 740.2 millimeters.
