Edna buys a bottle of dog shampoo that costs 3.99$. The bottle contains 28.5 ounces of shampoo. What is the cost per ounce of shampoo?
Answer: $0.14 per ounce
Step-by-step explanation:
There are 28.5 ounces of shampoo in the shampoo bottle and the cost of the whole bottle is $3.99.
The cost per ounces will therefore be:
= Cost of bottle / Number of ounces
= 3.99 / 28.5
= $0.14 per ounce

for numbers 19 and 20 you have to solve for the missing angle.
Answer:19. 17 degrees
20. 49 degrees
Step-by-step explanation:
Because of the postulate 50+?=67
So ?=17
And 20.
94+?=143
So
?=49
(Edit)I though you only meant 19 and 20

(SAT Prep) Find the value of x.
X
125°
115°
#look pic for detailed info
180° - 125° = 55°
180° - 115° = 65°
180° - 55° - 65° = 60°
180° - 60° = 120°
180° - 120° = 60°
Answer:
x = 120°
Step-by-step explanation:
you can draw a perpendicular base betweeen the two parallel segments and form a pentagon, which has 540 degrees inside.
the two base angles will each be 90°, and we have known values for the other two.
as far as 'x', that angle is vertical to the top angle of the pentagon so we add up all the known values and solve for 'x':
90 + 90 + 125 + 115 + x = 540
180 + 240 + x = 540
x = 540 - (180 + 240)
x = 540 - 420
x = 120

whats the best advice someone has gave you ?..
Answer:
dont say you don't know to be lazy and not work say you don't know when you haven't learned and need to.
The best advice someone has ever given me was to hold on and trust that God will bring me through the storms. There was a time in my life in which I felt the only escape from my troubles was death. Although "Hold on" doesn't sound very encouraging... looking back, it's what was needed for me to get to a point in my life where I cherish my existence.
Warm regards,
Bee
Jaden scores 100 points in the first round of a game. He earned 20 points in each of the following rounds of the game. He ended the game with 400 points. Write and solve an equation that could be used to determine the number of extra rounds Jaden played.
Answer:
100 + 20 x n = 400
Step-by-step explanation:
If he ended the game with 400 points, and he scored 100 points in the first round, and 20 points every round after that, then we have to find out how many rounds he played using multiplication and addition. n represents the number of rounds he played, which is what we want to find out. What number do you have to multiply 20 by to get 300? the answer is 10. Therefore, n is 10.
Hope this helped :)

-5(4x-6) help pls I am dead so I can't solve it.
Answer:
-20x+30
Step-by-step explanation:
Using distributive property take -5 and multiply 4x and -6 to that -5
That equals 4 x 5 is 20
add the negative -20
add the x -20x
-5 x -6 = 30
add the final product together

A student collects post cards from around the world. She has 150 post cards. Of these post cards, 42% are from Africa, 20% are from Europe, 10% are
from Asia, and the rest are from South America. How many post cards are from South America?
Answer:
42 post cards
Step-by-step explanation:
First, let's find how many cards are from each country by multiplying the decimal forms of the percent by the total number of post cards (150).
Reminder: to get the decimal form of a percent you move the decimal point twice to the left!
Africa: (.42)(150) = 63
Europe: (.20)(150) = 30
Asia: (.10)(150) = 15
Add all of them
63 + 30 + 15
= 108
Subtract it from the total
150 - 108
= 42
Another way to do this is to add up the percent's and then subtract it from 100, convert that to decimal form and multiply it by 150. Like this:
42% + 20% + 10% = 72%
100 - 72 = 28
(.28)(150) = 42
Therefore, 42 post cards are from South America.
I hope this helps!!

Which functions graph has a y-intercept of 2?
Answer:
The y-intercept is the constant [whole number, the one without a variable] in the equation. So you're looking for the equation that has + 2 at the end, not -2.

Write your question here (Keep it simple and clear to get the best answer)what is the domain of the function y=✓3-s?
Answer: D: s∈ (-∞, 3]
Step-by-step explanation:
When we have a function:
y = f(x)
The domain is the set of the possible values we can input in f(x).
In this case, we have:
y = √(3 - s)
Where our variable is s.
So we want to find the possible values of s we can input in that function.
Remember that if y is a real number, then we can not have a negative number inside the square root, because it will lead to an complex solution.
Then the argument of the square root needs to be equal to or larger than zero.
This means that:
3 - s ≥ 0
From this inequality, we can find the possible values of s, which will be the domain.
We need to isolate s.
3 ≥ s
This means that s needs to be smaller than or equal to 3.
Then the domain is:
D: s∈ (-∞, 3]
For camping mrjohn son needs 12 1-2 feet of rope to tie the logs that he has to cut for the campfire and 9 3-4 feet of the rope for the clothesline what is the total length of rope he needs for the camping trip
Answer:
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip
Step-by-step explanation:
To get the total length of rope Mr John needs for the camping trip, we can simply add up the length of rope he needs to tie the logs to the length of rope he needs for the clothesline.
Length of rope he needs to tie the logs = [tex]12\frac{1}{2}[/tex]
Length of rope he needs for the clothesline = [tex]9 \frac{3}{4}[/tex]
to sum this up, we, first of all, add up the whole numbers
12 + 9 = 21.
We then keep this aside then add up the fractions
[tex]\frac{1}{2} +\frac{3}{4} =\frac{2 +3}{4} = 5/4 = 1\frac{1}{4}[/tex]
We then add this to our whole numbers
[tex]21 + 1\frac{1}{4} =22 \frac{1}{4}[/tex]
Mr. John will need not less than [tex]22\frac{1}{4}[/tex] feet of rope for the camping trip

A rectangular garden has a length that is 3 feet longer than its width. Let w represent the width of the garden in feet. The entire garden is surrounded by a 2-foot-wide cement walkway.
Answer:
Step-by-step explanation:
From the question, we're told that the length of the garden is 3 feet longer than its width. Mathematically, we would have
l = w + 3, where
l = length of the garden
w = width of the garden
Again we're told that this same garden has a walkway of about 2 foot wide. Mathematically we would have that as
W(w) = 2, where
W(w) = width of the garden.
That's all the parameters given in the question

9514 1404 393
Answer:
2/3·fg
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(ab)^c = (a^c)(b^c)
(a^b)^c) = a^(bc)
__
We assume your 'x' is a multiplication symbol, so you want to simplify ...
[tex]3f^4g^3 \times\dfrac{ 8fg^4}{ (6f^2g^3)^2}\\\\=\dfrac{3\cdot8f^{4+1}g^{3+4}}{6^2f^{2\cdot2}g^{3\cdot2}}=\dfrac{24}{36}f^{5-4}g^{7-6}\\\\=\boxed{\dfrac{2}{3}fg}[/tex]
