Jenna made money babysitting, and she also earned $20 cleaning her neighbor's basement. During the week, her total earnings were $55. If she charges $5 per hour for babysitting, how many hours did she babysit?
Answer:
Jenna spent 7 hours babysitting.
Step-by-step explanation:
With the information provided, you can say that Jenna's total earnings are equal to the amount she earned cleaning her neighbor's basement plus the result of multiplying the charge per hour for babysitting for the number f hours, which is:
e=20+5x, where:
e represents the total earnings
x is the number of hours
Now, you can replace e with 55 that is the toal amount she earned and solve for x:
55=20+5x
55-20=5x
35=5x
x=35/5
x=7
According to this, the answer is that Jenna spent 7 hours babysitting.

Circumference using 3.14 as pi?
Students, draw anywhere on this slide!
Answer:
The circumference of the circle in term of pi = 10π inchesThe circumference of the circle us 3.14 as pi = 31.4 inchesStep-by-step explanation:
Given
The radius of the circle = r = 5 in
We know that diameter is twice the radius.
so d = 2r = 2(5) = 10 in
Finding the circumference of the circle in terms of pi
Using the formula to find the circumference of the circle
C = dπ
C = 10×π
C = 10π inches
Thus, the circumference of the circle in term of pi = 10π inches
Finding the circumference of the circle using π = 3.14
We know that the formula to find the circumference of the circle
C = dπ
Given
π = 3.14
substituting π = 3.14 to find the circumference of the circle
C = 10×3.14
C = 31.4 inches
Thus, the circumference of the circle = 31.4 inches
The height of a building is 1417 ft. How long would it take an object to fall to the ground from the top? Use the formula s = 16t ^ 2 where s is the distance, in feet traveled by an object falling freely from rest in seconds.
Given :
The height of a building is 1417 ft.
To Find :
How long would it take an object to fall to the ground from the top.
( Use the formula s = 16t² where s is the distance, in feet traveled by an object falling freely from rest in seconds. )
Solution :
Putting value of height in given equation, we get :
[tex]16t^2 = 1417\\\\t^2 = \dfrac{1417}{16}\\\\t^2 = 88.5625\\\\t = \sqrt{88.5625}\\\\t = 9.41 \ seconds[/tex]
Therefore, time taken by object to reach the ground is 9.41 seconds.

what percent of 120 is 66?
Answer:
55%
Step-by-step explanation:
66
120
x 100% = 55%
Answer:
66 is 55% of 120
Step-by-step explanation:
66 = 120 * x%
percent just means out of 100
for example, 20% is equal to 20/100
so, x% is x/100
66 = 120 * x/100
66/[tex]\frac{x}{100}[/tex] = 120
66 * 100/x = 120
6600/x = 120
cross multiply
6600/x = 120/1
6600 * 1 = x * 120
6600/120 = x
x = 55

what is -4 (-6x + 3) = 12
Answer: x = 1
Step-by-step explanation:
Simplifying
-4(-6x + 3) = 12
Reorder the terms:
-4(3 + -6x) = 12
(3 * -4 + -6x * -4) = 12
(-12 + 24x) = 12
Solving
-12 + 24x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + 12 + 24x = 12 + 12
Combine like terms: -12 + 12 = 0
0 + 24x = 12 + 12
24x = 12 + 12
Combine like terms: 12 + 12 = 24
24x = 24
Divide each side by '24'.
x = 1
Simplifying
x = 1

What is the rate of change of the function y= -7?
Answer:
Zero
Step-by-step explanation:
Average rate of change can also be called as gradient or change in the respective variable , in this case we need the average rate of change of y which has the function y = -7
Since this is a linear function and if we draw the graph of y = -7 the graph would be parallel to the x-axis, and any line parallel to the x-axis has slope of zero , hence the average rate of change of the function y = -7 is zero

What is the slope of a ski run that rises 5 feet for every horizontal change of 20 feet? Pls show work
Answer: -1/4
Step-by-step explanation: The slope is rise over run. The ski run drops 5, so it would be -5, and the horizontal change of 20 would be the run, so you'd get -5 over 20 then you divide both by 5 and you get your answer of -1 over 4.
-1/4 is the slope of a ski run that rises 5 feet for every horizontal change of 20 feet
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given the slope of a ski run that rises 5 feet for every horizontal change of 20 feet
So the two points are (0,5) and (20,0)
m=0-5/20-0
m=-5/20
m=-1/4
Hence -1/4 is the slope of a ski run that rises 5 feet for every horizontal change of 20 feet

Find the sum of the arithmetic series
3+8+13+..+438
Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404

Answer:
B. 9
Step-by-step explanation:
12 times 3/4 is 9
Answer:
it takes 4 of the 3/4 servings to make a whole number and it's 3 cups.
12/3= 4 and 4*4= 16
so 16 children can eat ice cream
or you could do 12/0.75= 16
you would do that because 3/4=0.75
you would divide and not multiply because you're seeing how many times 0.75 can go into 12
Step-by-step explanation:
A chart labeled table B: effect of mass on temperature with initial temperature as 25 degrees Celsius, mass w is 1.0 kilograms and h is 500 m. The chart is 5 columns and 5 rows. The first column is labeled mass c in kilograms with entries 1.0, 3.0, 6.0, 9.0. The second column is labeled temperature final in degrees celcius with entries 26.17, 28.52, 32.03, 35.55. The third column is labeled change in temperature in degrees celcius with entries 1.17, 3.52, 7.03, 10.55. The fourth column is labeled gravitational potential energy in kilojoules with no entries. The last column is labeled delta H in kilojoules with no entries. Use the data provided to calculate the gravitational potential energy of each cylinder mass. Round your answers to the nearest tenth. 3 kg: kJ 6 kg: kJ 9 kg: kJ
Answer:
3 kg= 14.7
6 kg= 29.4
9 kg= 44.1
Step-by-step explanation:
The gravitational potential energy of the cylinders as follows:
3 kg: 14.7 kJ, 6 kg: 29.4 kJ, and 9 kg: 44.1 kJ
What is the GPE?GPE is gravitational potential energy, mass is the mass of the object in kilograms, gravity is the acceleration due to gravity in meters per second squared (usually taken to be 9.8 m/s²), and height is the height of the object above the reference point in meters.
To calculate the gravitational potential energy (GPE) of an object, you need to know its mass, the acceleration due to gravity, and its height above a reference point. You can use the formula:
GPE = mass × gravity × height
In this case, the mass of each cylinder is given in the first column of the chart, and the height of the cylinders is 500 meters. However, the acceleration due to gravity is not given in the chart. We can assume that it is 9.8 m/s², but if you have a different value, you should use that instead.
Using these values, we can calculate the gravitational potential energy of the 3-kilogram cylinder as follows:
GPE = 3 kg × 9.8 m/s² × 500 m = 14700 kg m/s²
Converting this to kilojoules gives us:
GPE = 14700 kgm/s² × (1 J/1 kgm/s²) = 14700 J
Converting this to kilojoules (kJ) gives us:
GPE = 14700 J / 1000 J/kJ = 14.7 kJ
Therefore, the gravitational potential energy of the 3-kilogram cylinder is 14.7 kJ.
You can use the same process to calculate the gravitational potential energy of the 6-kilogram is 29.4 kJ and the 9-kilogram cylinders is 44.1 kJ.
