Felicity baby sat 2 hours each night for 10 nights. She earned a total of 180 babysitting. Felicity wants to calculate her hourly rate. How much did Felicity earn per hour babysitting?
Answers
Answer:
$9 per hour
Step-by-step explanation:
Total number of hours = hours each night x number of nights
⇒ Total number of hours = 2 x 10 = 20 hours
Hourly rate = total earned ÷ total number of hours
⇒ Hourly rate= 180 ÷ 20 = 9
Therefore, hourly rate = $9 per hour
Answer:
9 dollars per hour
Step-by-step explanation:
First determine the total number of hours
2 hours * 10 nights = 20 total hours
Divide the total amount paid by the total hours to get the rate
180 /20 = 9
She is paid 9 dollars per hour

The curved surface area of a right circular cylinder of height 14 cm is 88 cm².
Answers
Answer:
The diameter of the base of the cylinder is 2 cm.
Step-by-step explanation:
GIVEN :
As per given question we have provided that :
➣ Height of cylinder = 14 cm➣ Curved surface area = 88 cm²[tex]\begin{gathered}\end{gathered}[/tex]
TO FIND :
in the provided question we need to find :
➠ Radius of cylinder ➠ Diameter of cylinder[tex]\begin{gathered}\end{gathered}[/tex]
USING FORMULAS :
[tex]\star{\underline{\boxed{\sf{\purple{Csa = 2 \pi rh}}}}}[/tex]
[tex]\star{\underline{\boxed{\sf{\purple{d = 2r}}}}}[/tex]
➛ Csa = Curved surface area ➛ π = 22/7➛ r = radius ➛ h = height ➛ d = diameter[tex]\begin{gathered}\end{gathered}[/tex]
SOLUTION :
Firstly, finding the radius of cylinder by substituting the values in the formula :
[tex] \begin{gathered} \qquad{\longrightarrow{\sf{Csa = 2 \pi rh}}} \\ \\ \qquad{\longrightarrow{\sf{88 = 2 \times \dfrac{22}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{7} \times r \times 14}}} \\ \\ \qquad{\longrightarrow{\sf{88 =\dfrac{44}{\cancel{7}}\times r \times \cancel{ 14}}}} \\ \\ \qquad{\longrightarrow{\sf{88 =44 \times r \times 2}}} \\ \\ \qquad{\longrightarrow{\sf{88 =88 \times r}}} \\ \\ \qquad{\longrightarrow{\sf{r = \frac{88}{88}}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\pink{r = 1 \: cm}}}}}} \end{gathered}[/tex]
Hence, the radius of cylinder is 1 cm.
———————————————————————
Now, finding the diameter of cylinder by substituting the values in the formula :
[tex]\begin{gathered} \qquad{\longrightarrow{\sf{d = 2r}}} \\ \\ \qquad{\longrightarrow{\sf{d = 2 \times 1}}} \\ \\ \qquad{\longrightarrow{\underline{\underline{\sf{\red{r = 2 \: cm}}}}}}\end{gathered}[/tex]
Hence, the diameter of the base of the cylinder is 2 cm.
[tex]\rule{300}{2.5}[/tex]
CSA of a cylinder = 88 cm²
height = 14 cm
diameter = ?
CSA of a cylinder = 88 cm²
2πrh = 88 cm²
____[tex]2 \times \frac{22}{7} \times r \times 14 = 88 cm²[/tex]
[tex]2 \times \frac{22}{1} \times r \times2 \: = 88 cm²[/tex]
[tex]2 \times 22 \times r \times 2 = 88 cm²[/tex]
[tex]88r = 88 cm²[/tex]
[tex]r = \frac{88}{88} [/tex]
[tex]r = 1 [/tex]
____Diameter = radius + radius
= 1 + 1
= 2
____Therefore, The Diameter of the base of the cylinder is 2.A copy machine makes 36 copies per minute. How many does it make in 5 minutes and 15 seconds

Nick was surveying his field and saw some cows and ducks. Nick counted a total of 80 heads and
248 legs. Assuming there are no mutations in the animals, determine exactly how many ducks and
cows he saw. Let X represent the number of ducks and y represent the cows.
Total Equation:
Legs Equation:
How many ducks?
How many cows?
Answers
Answer:
44 cows and 36 ducks.
Step-by-step explanation:
x is ducks and y is cows.
Assuming both have 1 head each, we can write:
x + y = 80.
Let's assume each x(cow) has 4 legs and each y(duck) has two legs.
Then we can add the numbers of legs:
2x + 4y = 248 legs
Now rearrange x + y = 80 to:
x = 80-y
and substitute:
2x + 4y = 248 legs
2(80-y) + 4y = 248 legs
160 - 2y + 4y = 248 legs
2y = 88 legs
y = 44 [There are 44 cows]
Use this value to find the number of ducks:
x + y = 80
44 + y = 80
y = 36 [There are 36 ducks]
========================

Find the maximum area for a rectangle with a perimeter of 120 meters.
Answers
Answer:
900 m^2
Step-by-step explanation:
Let x = length, y = width
perimeter = 2x + 2y = 2(x + y) = 120. so
x + y = 60, or y = 60 - x
Area = xy = x(60 - x) = 60x - x^2
= -(x^2 - 60x + 30^2) + 30^2
= 900 - (x - 30)^2
Note (x - 30)^2 is never negative, at least zero.
When (x - 30) = 0, the area is the largest which is 900 m^2

Trapezoid :- It is the quadrilateral whose all sides are non parallel to each other Parallelograms :- It is the quadrilateral having opposite sides parallel Kite :- It quadrilateral with no parallel Trapezium :- It is a quadrilateral having one pair of parallel sides.Hence, Option b is correct
Answer 2 :-The two consecutive angles of parallelogram are Supplementary.
Supplementary angles are those angles whose sum equal to 180°.The sum of two consecutive angles are parallelogram is 180° .Hence, Option C is correct
Answer 3 :-All squares are rectangle is true statement
All squares are rectangles because square having length and breath .All rhombus is rectangle is a false statement because all sides of rhombus are equal which is not in the case of rectangle All rectangles are squares is a false statement because all sides of square are equal whereas in rectangle only opposite sides are equal. Every parallelogram is a rhombus is false statement because rhombus has all four sides equal but parallelogram Only having opposite sides equal.Hence, Option A is correct

Some help with some of this transformation on linear functions would help, you don’t have to necessarily answer all of them, just if you answer two or three i’d be really grateful ;w;
Answers
Answer:
1. f(x) - 7
2. The lines do not have same x-intercept
3. a(x) = f(x+7)
4. b(x) = f(x-3)
5. c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x-8)
b. Slope of g(x) = 1
c. y-intercept = (0, -8)
7. a. p(x)=f(x+6) is vertical transformation of f(x) = x. f(x) is the parent function.
b.(please check explanation section.)
For the second page, here are the answers
5.
a. False
The slope of f(x) will be steeper than m(x)
b. False
The y-intercept doesn't change due to multiplication of 3/5
6. C. h(x) = 3f(x-5)
7. d(x) = 1/4 f(x) + 9
8. Erika: c(x) = 4f(x) + 4 is the first graph
Landry: c(x) = -4f(x) + 3 is the second graph
Step-by-step explanation:
1. f(x) - 7 = x - 7 ( y intercept is translated down when g(x) = x - k )
2. The lines do not have same x-intercept. ( x-intercept of f(x)=x is (0,0) and that of f(x-10) is (0,10)
3. a(x) = f(x) + 7 = x + 7 = f(x+7)
4. b(x) = f(x) - 3 = x - 3 = f(x-3)
5. c(x) = f(x) + 5 = x + 5 = f( x+5)
c(x) = f(x) + 5 and c(x) = f(x+5) are two functions that can represent c(x)
6. a. g(x) = f(x) - 8 = x -8 = f(x-8)
b. Slope of g(x) = Slope of f(x)
Slope of f(x) = d(f(x)/dx = dx/dx = 1
Therefore Slope of g(x) = Slope of f(x) = 1
c. y-intercept = (0, -8) (In this case The y-intercept of g (x)=f(x-8) is translated down as -8<0 by 8 units.)
7. b. Look at the graph for part b

Jim is 4 years older than mark if the sum of their ages is 44 find the age of each person
Answers
Answer:
jim is 24 years old, Mark is 20 years old
Step-by-step explanation:
This prompt can be set up using this equation:
Let's represent Mark's age by variable m and Jim's age by variable J.
j + m = 44
m + 4 = j
m = j - 4
j + (j - 4) = 44
2j - 4 = 44
2j = 48
j = 24
So, jim is 24 years old, meaning mark must be 20 years old. 20 + 24 results in 44 years old together.

Answers
Answer:
The first part is correct! → There are 4 distinct instruments to distribute to 4 distinct people. And there are 4!=24 distinct ways of doing this.
For the second part. → Jay and Jack can only play 2 instruments, therefore we have 2 instruments for 2 people, and the distribution for these guys can be made in 2!=2 distinct ways.
Then, note that all that is left are 2 distinct instruments for 2 people. So there is an additional 2 distinct ways of doing this distribution for these other guys.
By the product rule, in total, we can do 4 distinct distribution in this condition.
