Amanda earns $30 per week for her allowance, plus $15 dollars per hour babysitting. She wants to earn at least $150 each week.?
Write a function F(h) to represent the situation.
How many hours must Amanda babysit each week?
Answer:
f(h)=15(8)+30
8 Hours per week
Step-by-step explanation:
$30 per week means she has a start of $30, so this will be a constant.
What we want to find is how much she needs to work to earn the remaining amount, $120.
To find that we need to divide $120/15, giving us 8.
She needs to work 8 hours per week. This gives us the function
x=15(8)+30
Answer:
She will have to work 8 total hours that week.
Step-by-step explanation:
a. Find the mean, median, and mode of 12, 9, 17, 15, 10.
mean:
median:
6
Answer:
Mean: 12.6
Median: 12
Mode: None
Step-by-step explanation:
To find the mode, add everything up.
12 + 9 + 17 +15 + 10 = 63. Then, divide by five.
63 ÷ 5 = 12.6
To find the median, put the numbers from least to greatest. Then, highlight the one in the middle.
9, 10, 12, 15, 17
To find the mode, look for the number that appears the most. Because each number appears once. So, put "none" in the box.
Have a wonderful day!

Answer:
59 degrees
Step-by-step explanation:
Since angle BGC is 40 degrees and angle AGC is 19 degrees and they are asking for angle AGB which is the sum of both angles together, you just add the 40 degrees plus 19 degrees.
Find the equation of the line that is parallel to the line y = 2x - 5 and passes through the point (-1,3).
Answer:
y=2x+5
Step-by-step explanation:
If you graph it you can figure out the starting point of the parallel line.
The rate of change is 2 and since the point the parallel line needs to pass through is (-1,3) you need to shift the starting point (y-intercept) up by 10 units.
Shifting the y-intercept of y=2x-5 up by 10 makes the new line y=2x+5.
On Monday, Amanda had $231.56 in her savings account. She then bought
a new pair of jeans for $87.85, as well as 2 movie tickets for $19.90 after tax. She also bought 2 containers of popcorn that were $7.49 each. If Amanda used her debit card for all of these purchases, and all prices include tax, how much does Amanda have left in her bank account after all of these transactions. (Show All Your Work).
Solve 252x−1=400 for x.
Which answer shows the correct steps?
Answer:
1.75
Step-by-step explanation:
252x-1=400
First we need to isolate the x in one side of the equation
Lets add 1 to each side of the equation to get rid of -1
252x=441
now we divide 441 by 252 to get x
x=1.75
UPDATE
The owner of the question said its supposed to be 25^2x -1 =400
ok lets do this
25^2 * x=401
625x =401
x=.6416

Angle BAC and angle DAE are
complementary. What is the
measure of angle DAE?
Answer:
44 degrees
Step-by-step explanation:
if BAC and DAE are complementary then their sum is equal to 90 degrees
90 - 36 = 44 degrees
Answer:
54
Step-by-step explanation:
your suppose to substract 90 degrees minus 36 = 54
90-36=54

The floor of a rectangular cage has a length 4 feet greater than its width, w. James
will increase both dimensions of the floor by 2 feet. Which equation represents the
new area, N, of the floor of the cage?
Answer:
x² + 8x + 12
Step-by-step explanation:
Area of a rectangle = length × width
Original dimensions:
Width = x
Length = x + 4
James will increase both dimensions of the floor by 2 feet
New dimensions:
Width = x + 2
Length = x + 4 + 2
= x + 6
Area of the new rectangle = length × width
= (x + 2) × (x + 6)
= x² + 6x + 2x + 12
= x² + 8x + 12
Equation which represents the
new area, N, of the floor of the cage = x² + 8x + 12
Which can be represented by the expression 17 – 2x? A. 17 less than twice a number B. the difference between 17 and twice a number C. a number x squared, subtracted from 17 D. 17 less than a number x squared
Answer:
B.
Step-by-step explanation:
If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.
Common Error:
A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.
Hope this answer helped! :)
It moves in a straight line starting from rest. It travels with a constant acceleration for 3 seconds reaching a velocity of 4 m/s. Then it slows down with a constant deceleration of 0.5 m/s squared for 4 seconds before stopping what is the total distance travelled by the toy car?
Answer:
The total distance traveled by the toy car is 14 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 0
final velocity of the car, v = 4 m/s
time of motion, t₁ = 3 s
constant deceleration of the car, -a = 0.5 m/s²
time of motion, t₂ = 4 s
The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).
[tex]Total \ distance = Area = \frac{1}{2} |BC| \times H\\\\Total \ distance = \frac{1}{2} \times 4\times 7\\\\Total \ distance = 14 \ m[/tex]
Hunter is splitting a quart of ice cream with 7 family members if the quart is split evenly how many cups will each family member get
Answer:
1.75 or about 1 cup of ice cream
Step-by-step explanation:
Well, we first have to figure out how many cups of ice cream are in a quart. (There are 4 cups in a quart) So know we have to divide 4 into 7 that will give you 1.75 so each family would get approximatley 1.75 cups of ice cream. That is if it is talking about specifically how much ice cream but you could also say about a cup

3
of her supply of cranberries to make bread and 49
4
9
of her supply of cranberries to make granola. If Melanie uses 7 pounds of cranberries, how many pounds of cranberries are in her supply?
Answer:
She has 9 pounds
Step-by-step explanation:
Given
[tex]Bread = \frac{1}{3}[/tex]
[tex]Granola = \frac{4}{9}[/tex]
[tex]Used = 7[/tex]
Required
The total in her supply
Represent the cranberry with c.
So:
[tex]\frac{1}{3}c + \frac{4}{9}c = 7[/tex] ---- Used cranberry
Take LCM
[tex]\frac{3c + 4c}{9} = 7[/tex]
[tex]\frac{7c}{9} = 7[/tex]
Solve for c
[tex]c= 7 * \frac{9}{7}[/tex]
[tex]c= 9[/tex]
Which of the following is the result of the equation below after completing the square and factoring?
x2+3x+8=6
Will mark brainliest
Answer:
D)
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4
Answer:
D is the answer
Step-by-step explanation:
x² + 3x + (3/2)² = 6 - 8 + (3/2)²
(x + 3/2)² = -2 + 9/4
(x + 3/2)² = -8/4 + 9/4
(x + 3/2)² = 1/4
Hope this helps you ;)

8
y
Find
y
when
x
=
4
and
R
=
32
Answer:
R = 4x + 8y
-8y = 4x - R
-8y = 4(4) - 32
-8y = 16 - 32
-8y = -16
we divide through by -8
so now
y = 2

Answer:
Step-by-step explanation:
Not 3-3 (which is subtraction), but 3^3 (which involves exponentiation.
3^3 = 27
Also: 2^3 = 8; 5^3 = 125
You will see lots of exponentiation in math; please practice and ask questions about it if you have any doubts.
