Lia must work at least 5 hours per week in her family’s restaurant for $8 per hour. She also does yard work for $12 per hour. Lia’s parents allow her to work a maximum of 15 hours per week overall. Lia’s goal is to earn at least $120 per week.

1.)Write a system of inequalities to represent this situation. Let r be the number of hours worked at the restaurant, and let y be the number of hours of yard work.
2.)Graph the inequalities.
3.)What is the maximum number of hours Lia can work at the restaurant and still meet her earnings goal? Explain.
4.)What is the maximum amount of money Lia can earn in 1 week? Explain.

Answers

Answer 1
(1) r+y<=15 
r>=5 
8r+12y>=120 
(3) assuming she will work 15 hours, y = 15-r 
so 
8r + 12(15-r) >= 120 
8r+180-12r>=120 
-4r+180>=120 
-4r >= -60 
r <= 15 
looks like she could work all 15 hours and still make 120 dollars 
(4) r= 5 required hours in the restaurant then 
8r + 12(15-r)= 160

A rectangular playground is to be fenced off and divided in two by another fence parallel to one side of the playground. 648 feet of fencing is used. find the dimensions of the playground that maximize the total enclosed area.

Answers

A rectangular playground of sides a and b would have an area of a*b. The perimeter of the fence plus one side is 648ft; this can be written as 3a+2b. We can write b in the expression for the area as (648-3a)/2. The area is equal to (648a-3a^2)/2; the maximum value can be found by deriving the area expression and equate it to 0. The derivative is 324-3a; the value of the area is maximum when a=108ft. The dimensions that maximize the playground are a=108ft and b=162ft.

Find the value of ‘x' and the length of segment ab. if b is between a and c, and ab = 3x – 3 and bc = 4x + 8, and ac = 75, then find the value of ‘x' and ab. answer

Answers

Final answer:

To solve for 'x' and the length of segment AB, we use the equation AB + BC = AC, which simplifies to (3x - 3) + (4x + 8) = 75, revealing that 'x' = 10 and the length of AB is 27 units.

Explanation:

The question requires us to find the value of 'x' and the length of segment AB given that B is between A and C, with AB = 3x – 3, BC = 4x + 8, and the total length AC = 75. To solve this, we set up an equation using the given lengths of segments AB and BC to equal the total length AC. This gives us the equation AB + BC = AC, which simplifies to (3x – 3) + (4x + 8) = 75.

First, we simplify the equation: 3x + 4x – 3 + 8 = 75, which reduces to 7x + 5 = 75. Subtracting 5 from both sides gives us 7x = 70. Dividing both sides by 7, we find that x = 10. With the value of x, we can find AB by substituting x back into its equation: AB = 3(10) – 3 = 30 – 3 = 27.

Therefore, the value of 'x' is 10 and the length of segment AB is 27 units.

The value of x is 9.7 inches, rounded to the nearest tenth.

Answer:

B. 9.7 in.

Step-by-step explanation:

We have been given an image of a triangle. We are asked to find the value of x.

We will use area of triangle formula to solve our given problem.  

[tex]\text{Area of triangle}=\frac{1}{2}\times \text{Base*Height}[/tex]

[tex]47\text{ in}^2=\frac{1}{2}\times x*x[/tex]

[tex]2*47\text{ in}^2=\frac{1}{2}*2\times x^2[/tex]

[tex]94\text{ in}^2=x^2[/tex]

Taking square root of both sides we will get,

[tex]x=\sqrt{94\text{ in}^2}[/tex]

[tex]x=9.6953597\text{ in}\approx 9.7\text{ in}[/tex]

Therefore, the value of x is 9.7 inches and option B is the correct choice.

A giraffe can run 32 miles per hour. What is this speed in feet per second? Round your answer to the nearest tent.

Answers

ANSWER: 46.9 feet per second

32 miles per hour
5280 feet in 1 mile
32 x 5280 = 168,960 feet per hour
3600 seconds per hour

168,960 divided by 3600 = 46.9333 (continuous)
rounded to the nearest tenth is 46.9 feet per second.

Speed is the rate of change of distance over time.

The speed in feet per seconds is 46.9

The speed of the giraffe is given as:

[tex]\mathbf{Speed = 32 miles/hour}[/tex]

Start by converting miles to feet

To do this, we multiply 32 by 5280.

So, we have:

[tex]\mathbf{Speed = 32 \times 5280feet/hour}[/tex]

[tex]\mathbf{Speed = 168960feet/hour}[/tex]

Next, convert hour to seconds

To do this, we divide by 36000.

So, we have:

[tex]\mathbf{Speed = \frac{168960}{3600} feet/seconds}[/tex]

[tex]\mathbf{Speed = 46.9 feet/seconds}[/tex]

Hence, the speed in feet per seconds is 46.9

Answers

Answer: Hello mate!

in the graph you can see that:

Jonathon does 2 pushups when he does 15 crunches.

then he does 4 = ( 2+ 2) pushups when he does 30 = (15 + 15) crunches

this means that he does 2 pushups more than before, and 15 crunches more than before.

and 6= (2 + 2 +2) pushups when he does 35 =(15 + 15 + 15) crunches.

this, again, means that he does 2 pushups more than before, and 15 crunches more than before.

then you can see that he does 2 pushups for every 15 crunches.

hope this helps
Final answer:

The next three terms in the number pattern 0.57, 0.66, 0.75, 0.84 are 0.93, 1.02, and 1.11. The rule for the pattern is that each term increases by 0.09 from the previous term.

Explanation:

The given sequence is: 0.57, 0.66, 0.75, 0.84, ... The step or difference between each consecutive term is 0.09. Therefore, the next three numbers in the sequence would be: 0.84 + 0.09 = 0.93, 0.93 + 0.09 = 1.02, 1.02 + 0.09 = 1.11. So the answer is 0.93, 1.02, 1.11.

The generalized rule for this series is that each term increases by 0.09 from the previous term. In mathematical terms, if we denote the nth term as Tn, then Tn+1 = Tn + 0.09. This rule tells us that the number pattern involves adding 0.09 for each subsequent term in the sequence.

WXY is an isosceles triangle with line WX congruent to line WY. if WX is 3 more than four times x, XY is 7 less than five times x, and WY is 66 less than seven times x, find x and the measure of each side.

Answers

Answer:

x=10

Step-by-step explanation:

part 1:

4x+3=5x-7

(subtract 4x from 5x to get 1x and add 7 to 3 to get 10)

1x=10

x=10

part 2:

WX=4(10)+3=43

XY=5(10)-7=43

WY=7(10)-66=4

An isosceles triangle, have two congruent sides.

The value of x is 23The measure of each side is 95, 95 and 108

From the question, we have the following highlights

[tex]\mathbf{WX = WY}[/tex]

[tex]\mathbf{WX = 3 + 4x}[/tex]

[tex]\mathbf{XY = 5x - 7}[/tex]

[tex]\mathbf{WY = 7x - 66}[/tex]

(a) Find x

We have:

[tex]\mathbf{WX = WY}[/tex]

Substitute values for WX and WY

[tex]\mathbf{3 + 4x = 7x - 66}[/tex]

Collect like terms

[tex]\mathbf{7x - 4x = 3 + 66}[/tex]

[tex]\mathbf{3x = 69}[/tex]

Divide both sides by 3

[tex]\mathbf{x = 23}[/tex]

Hence, the value of x is 23

(b) The measure of each side

Substitute 23 for x in:

[tex]\mathbf{WX = 3 + 4x}[/tex]

[tex]\mathbf{XY = 5x - 7}[/tex]

[tex]\mathbf{WY = 7x - 66}[/tex]

[tex]\mathbf{W = 3 + 4 \times 23}[/tex]

[tex]\mathbf{W = 95}[/tex]

[tex]\mathbf{XY = 5x - 7}[/tex]

[tex]\mathbf{XY = 5 \times 23 - 7}[/tex]

[tex]\mathbf{XY = 108}[/tex]

[tex]\mathbf{WY = 7x - 66}[/tex]

[tex]\mathbf{WY = 7 \times 23 - 66}[/tex]

[tex]\mathbf{WY = 95}[/tex]

Hence, the measure of each side is 95, 95 and 108

Which graph represents a function?

Answers

Answer:

1st and last one

Step-by-step explanation:

the first and the last one are the only ones that represent a function because for each value of x there is only one corresponding value of y.

Final answer:

A graph represents a function if each value of x corresponds uniquely to a value of y. These graphs, often called line graphs, can depict various types of functions like linear, quadratic, etc. The slope and position of the line will vary depending on the function's formula.

Explanation:

In the subject of Mathematics, specifically when dealing with functions and graphs, a graph represents a function if each value of x corresponds to a unique value of y. This means that different values of x will produce different values of y. Graphs can be produced using specific pairs of (x,y) data points.

These graphs may be named line graphs as they showcase the relationship between two variables: one measured on the horizontal axis (x) and the other on the vertical axis (y). An example could be a function where y = a + bx. If b > 0, the line of the graph slopes upward to the right. If b = 0, the line is horizontal. If b < 0, the line slopes downward to the right.

Graphs may also represent other types of functions like linear, quadratic, inverse, or exponential, depending on the equation of the relation between x and y. It's also important to note that there can be other types of graphs, such as a specific type of line graph shown, where the x-axis consists of data values and the y-axis consists of frequency points.

In a salsa recipe, the number of tomatoes added is proportional to the amount of salt added. This graph shows the relationship.

What is the unit rate for the number of tomatoes to the tsp of salt?

Answers

 y=3x, y being the number of tomato and x, the number of tbs, then:

1 tbs correspond to 3 tomatoes

Answer:

The unit rate for the number of tomatoes to the tsp of salt is 3.

Step-by-step explanation:

Consider the provided graph.

The equation of the line is [tex]y=3x[/tex]

A unit rate is a rate with 1 in the denominator.

Here, the meaning of unit rate is how much tomatoes to the tsp of salt.

As we know the slope intercept form is:

[tex]y = mx + b[/tex]

Where,  m is the slope of the line or rate and b is y intercept.

By the comparison we can say that the slope of the line is 3. Here, the denominator is 1.

This shows that 3 tomatoes are added for each teaspoon of salt.

Hence, the unit rate is 3.
