Justice earned $36 for mowing 3 lawns in his neighborhood. Write the equation that would represent this situation. Use x to represent the number of lawns mowed and y to represent the amount of money Justice earned.
Answer:
To solve this problem, you need to set up the equations.
First, choose variables.
Let x = number of hours mowing lawns
Let y = number of hours working clothing store
Money from both jobs must be at least $350
(350 or more)
12x + 10y ≥ 350
Solve for y in order to graph
y ≥ -12/10x +35
Minimum of 10 hours at the store
y ≥ 10
No more than 35 hours a week
x + y ≤ 35
Solve for y to graph
y ≤ -x + 35
Making the graph: Number x and the y-axis from 0 to 35
First equation: y ≥ -12/10x + 35
y-intercept is 35
slope: a solid line starting at 35 on the y-axis, go down 12, over 10
The shade above solid line
Second equation:
y≥ 10
Make a solid horizontal line at y=10
The shade above the line for greater than.
Third equation:
y ≤ -x +35
Starting at y-intercept (0,35)
Solid line, Count slope down 1 and over 1
Shade underline
The overlapping area on the graph will look like a narrow triangle: above the horizontal line, under the line from the third equation, and above the line of the first equation.
The shaded area of the graph represents all the possible combinations of hours for mowing lawns and working in the clothing store that meets the requirements based on the pay and time.

Can someone help me with this thank you
Answer:
Step-by-step explanation:
Area of square = side * side
= 4 * 4
= 16 sq.ft
Area of triangle = [tex]\frac{1}{2}*base*height\\[/tex]
[tex]= \frac{1}{2}*4*2\\\\= 4 sq.ft[/tex]
Area of the figure = area of square + area of triangle
= 16 + 4
= 20 sq.ft
Help! The measure of the exterior angle of the triangle is???
Answer:
92°
Step-by-step explanation:
The exterior angle is equal to the sum of the 2 opposite interior angles, that is
2x - 2 = x + 45 ( subtract x from both sides )
x - 2 = 45 ( add 2 to both sides )
x = 47
Then
exterior angle = 2x - 2 = 2(47) - 2 = 94 - 2 = 92°
David has a bag of coins. The bag contains 7 dimes, 2 nickels, and 6 pennies. He will randomly select 2 coins from the bag one at a time
without replacement. What is the probability that David will select a dime first and then a penny?
Answer:
7/15 for dime
6/15 for pennies
Step-by-step explanation:
7/15 because 7+2+6=15 and there are 7 dimes so 7/15.
6/15 because there are 15 coins and there are 6 pennies so 6/15.
15 is the total so 7 and 6 have to go over it.

Scarlett went shopping for a new pair of pants. Sales tax where she lives is
4%. The price of the pair of pants is $41. Find the total price including tax.
Round to the nearest cent.
Answer:
39.36
Step-by-step explanation:
1% of 41 is .41, so you multiply that by 4 to get 1.64. Then do 41-1.64=39.36
The total price including tax is $42.64
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
Price of pants= $41
Sales tax= 4%
So, the tax is
= 41 x 4%
= 41 x0.04
= $1.64
Now, the price of pants after tax
= 41 + 1.64
= $42.64
Hence, the total price including tax is $42.64

The interquartile range is (the middle of the upper half) - (the middle of the lower half). To find this list out all of the values and find the median, then find the center of the upper half and the lower half.
1 2 2 3 3 3 4 4 5 6 Here I have made a small diagram of how you were to find the middle of each half with the underline being each half, the bold being the sides for each half, and the italicized being the value. For this question the middle of the upper half is 4 and the middle of the lower half is 2, so 4-2 = 2.
If Brenda decides to use milliliters and leaders in terms room instead and each person at the party will drink about 750 mL after 32 people and they each drink about 750 mL how many liters of punch open does mom need to buy?
Answer:
24 litres
Step-by-step explanation:
Given that :
Number of people present at party = 32
Volume of drink consumed by each person in mL = 750 mL
To consumption in mL:
Number of people * volume consumed by each
32 * 750 mL
24000 mL
24000 mL to L
1000 mL = 1 L
24000 mL = (24000/ 1000)L
= 24 L

Answer: The 4th term is 11.
Step-by-step explanation:
The given sequence: [tex]C(n) = -7 + 6(n - 1)[/tex] which represents the nth term.
To find 4th term.
Put n=4, we get
[tex]C(4) = -7 + 6(4 - 1)\\\\\Rightarrow\ C(4) = -7 + 6(3)\\\\\Rightarrow\ C(4) =-7+18\\\\\Rightarrow\ C(4) =11[/tex]
Hence, the 4th term is 11.

A walkway forms one diagonal of a square playground. The walkway is 24 m long. How long is a side of the playground?
The diagonal of a square can be obtained by the Pythagorean theorem and is given by:
Diagonal = root (L ^ 2 + L ^ 2)
Where,
L: Sides of the squares
Clearing L, we have:
(Diagonal) ^ 2 = L ^ 2 + L ^ 2
(Diagonal) ^ 2 = 2L ^ 2
L ^ 2 = ((Diagonal) ^ 2) / 2
L = (((Diagonal) ^ 2) / 2) ^ (1/2)
Substituting
L = (((24) ^ 2) / 2) ^ (1/2) = 16.97
The side of the playground is 16.97m long

What is the volume of this cone?
Answer:
(1/3)πr2h.
Step-by-step explanation:
Volume of a cone:
V = (1/3)πr2h
Slant height of a cone:
s = √(r2 + h2)
Lateral surface area of a cone:
L = πrs = πr√(r2 + h2)
Base surface area of a cone (a circle):
B = πr2
Total surface area of a cone:
A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))

9514 1404 393
Answer:
110°
Step-by-step explanation:
The total of the ratio units is 11 +2 +5 = 18. These stand for the total of angles, 180°, so each ratio unit stands for 180°/18 = 10°.
The largest angle is 11 ratio units, or 11×10° = 110°.
