Leah would like to earn at least $120 per month. She babysits for $5 an hour and works at an ice cream shop for $10 per hour. Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop.
This question is incomplete
Complete Question
Leah would like to earn at least $120 per month. She babysits for $5 per hour and works at an ice cream shop for $10 per hour. Leah cannot work more than a total of 20 hours per month. Let x represent the number of hours Leah babysits and let y
represent the number of hours Leah works at the ice cream shop.
Answer:
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120
Step-by-step explanation:
Let x represent the hours she number of hours she babysits and y represent the hours she works at the ice cream shop. Leah cannot work more than a total of 20 hours per month.
Hence:
x + y ≤ 20 ...... Equation 1
Leah would like to earn at least $120 per month.
She babysits for $5 an hour and works at an ice cream shop for $10 per hour.
Hence, out Equation is given as:
x × $5 + y × $10 = $120
5x + 10y ≥ 120..... Equation 2
The inequalities to solve this question is given as:
x + y ≤ 20
5x + 10y ≥ 120
To find x and y:
x + y = 20
x = 20 - y
5x + 10y = 120
Substitute: 20 - y for x
5(20 - y) + 10y = 120
100 - 5y + 10y = 120
Collect like terms
- 5y + 10y = 120 - 100
5y = 20
y = 20/5
y = 4 hours
Note:
x = 20 - y
x = 20 - 4
x = 16 hours
Hence:
Leah must spend: 16 hours babysitting and 4 hours working at the ice cream shop to earn at least $120

If f(x) = 4x and g(x) = x^3, then what is f(g(x))?
a. 4x+x^3
b. 4x^4
c. 4x^3
d. (4x)^3
Answer:
f(g(x)) = 4x³
Hence, option C is true.
Step-by-step explanation:
Given
[tex]f(x) = 4x[/tex][tex]g\left(x\right)\:=\:x^3[/tex]Determine:
f(g(x)) = ?
solving the f(g(x))
f(g(x)) = f(x³)
= 4x³
Therefore,
f(g(x)) = 4x³
Hence, option C is true.

eighteen 2.5- gallon buckets are needed to fill a cistern of water
How many 3-gallon buckets of water will fill the cistern.
Answer:
15 3-gallon buckets of water will fill the cistern
Step-by-step explanation:
Eighteen 2.5- gallon buckets are needed to fill a cistern of water
This means, 2.5 gallon buckets in 18 places
2.5 gallons × 18 = 1 cistern of water
45 gallons = 1 cistern of water
How many 3-gallon buckets of water will fill the cistern.
Number of 3-gallon bucket in a cistern = Total gallons of bucket in one cistern / 3-gallon buckets
= 45 gallons / 3-gallon buckets
= 15
Number of 3-gallon bucket in a cistern = 15
15 3-gallon buckets of water will fill the cistern

SOLVE AND SHOW WORK PLSSSS!! Find the length of the missing sides. Do not round (leave in simplified radical form).
Answer:
For the first triangle the missing sides are 7 and 7√2 For the second triangle,the missing sides are 13√3 and 13
Step-by-step explanation:
For the first triangle,
cos(45°)=7/hypotenuse
hypotenuse×cos45=7
hypotenuse×√2/2=7
hypotenuse=14/√2=7√2
We can now find the adjacent side using Pythagorean theorem,
√(7√2)²-7²=7
For the second triangle,
cos(30°)=adjacent/hypotenuse
but cos 30=√3/2
√3/2=adjacent/26(cross multiply and simplify)
26√3/2=13√3
To find the opposite length,
√(26)²-(13√3)²=13

EASY MATH PROBLEM!
Please help me! Will mark brainliest for sure!
Answer:
A
Step-by-step explanation:
Answer:
The answer would be A
Step-by-step explanation:
Use the formula for |A| <= B which is: -B <= A <= B
For this example you would do:
1. Insert the numbers into the formula: -6 <= 2x - 8 <= 6
2. first do the math for -6 <= 2x-8 which is 1 <= x
3. then do the math for 2x - 8 <= 6 which is x <= 7
4. Put that together and you get 1 <= x <= 7

Select the locations on the number line to plot the points 9/2 and −7/2.
Answer:To plot these points on the number line, you should label the long lines on the number line as such starting from the left (-5-already there, -4,-3,-2,-1,0,1,2,3,4,5-already there).
Now take each number and convert the improper fraction into a mixed number. 9/2 = 4 1/2 and -7/2 = -3 1/2.
4 1/2 would plotted on the line exactly in between the 4 and 5.
-3 1/2 would be plotted on the line exactly halfway between -3 and -4.
You will draw a dot to show each of these positions on a number line.

There are 16 forwards and 40 guards in Leo's basketball league. Leo must include all players on a team and wants each team to have the same number of guards. If Leo creates the greatest number of teams possible, how many guards will be on each team?
List the multiples of each number:
16: 1, 2 , 4, 8 , 16
40: 1, 2 , 4 , 5, 8, 10, 20, 40
The greatest common multiple is 8
40 guards / 8 = 5
There will be 5 guards on each team.

Luis distributes 49 roses equally among seven friends then three of his friends combined the roses they received to make a bouquet how many roses are in this bouquet there are blank roses in this bouquet
Answer:
The are 21 roses in the bouquet
Step-by-step explanation:
Since the 49 roses are distributed evenly amongst the 7, then what each of the seven will get would be 49/7 = 7 roses
So 3 of the friends combine every of theirs to make a bouquet
The number of roses in the bouquet will be 7 + 7 + 7 = 21 roses
At the beginning of a laboratory experiment, the temperature of a substance is -12.6 °C. During the experiment, the temperature of the substance decreases 7.5 °C. What is the final temperature of the substance?
!!!!SHOW YOUR WORK!!!!
Answer
20.1°C
Step-by-step explanation:
-12.6 °C - 7.5 °C =-20.1°C
Answer:
the initial temperature= -12.6⁰c
change in temperature= 7.5⁰c
the final velocity = x
-12.6-7.5=x
-20.1=x
so therefore the final temperature is -20.1

x = 3.464 ft.
Step-by-step explanation:
To find x we use the trigonometric identity Sine.
[tex]sin\ \theta=\frac{perpendicular}{hypotenuse}\\\\sin\ 60=\frac{x}{4} \\\\4*sin60=x\\4*0.866=x\\3.464=x\\x=3.464\ ft[/tex]
Answer:
x = 3.464 ft.
Step-by-step explanation:
Given f(x) and g(x) = f(x) + k, use the graph to determine the value of k.
Explanation:
Start at a point like (0,2) which is on the blue f(x) line.
Move upward until you reach the red g(x) line. You should move up 3 units. Every point on f(x) follows the same pattern to land on a corresponding point on g(x). Therefore, this moves the entire blue line up 3 units.
This leads to k = 3
So g(x) = f(x) + 3
Answer: 3
Step-by-step explanation: This is because I took the test and because if you look at the graph its on 5 and 2. An easy way to look at it is what is 5-2 but you'd have to figure out what the answer was first. Between 5 and 2 is 3. Hope this helped!

12) It takes Kendra 12 minutes to drive 6 1/3 kilometers. How many kilometers does Kendra drive per minute? SHOW YOUR WORK. A) 2 B)19/36 C)1/6 D) 2 1/3
Answer:
36/19
Step-by-step explanation:
So to find this answer you have to divide 12 by 6 1/3. To figure that out I first turned 6 1/3 into an improper fraction (19/3) and then I put 12 over 1. To divide a fraction you have to multiply the dividend by the divisors reciprocal in this case 12/1 x 3/19 which equals 36/19 or 1 and 17/19

2/11z-5/11z+4-1/11z-8
simplify plssss i can give reward
Answer:
-145/88z+4
Step-by-step explanation:
Answer: -4/11z - 4
Step-by-step explanation: We can combine like terms to simplify the expression 2/11z - 5/11z + 4 - 1/11z - 8. The terms 2/11z, -5/11z, and -1/11z are like terms because they all have the same variable part z. When we add them together, we get (2 - 5 - 1)/11z = -4/11z. The constants 4 and -8 are also like terms. When we add them together, we get 4 + (-8) = -4. So the simplified expression is -4/11z - 4.
