Answer:
The first, second, and fourth questions.
Step-by-step explanation:
None of these result in an answer of 23, so I'm assuming that you meant 2/3.
"Two gallons of water are needed to fill 3 fish tanks of equal size. How many gallons of water are required for each tank?"
2 gallons divided between 3 tanks is 2 divided by 3, so 2/3.
"Three cats share 2 cans of tuna. How much of a can does each cat receive?"
2 cans divided between 3 cats - it's the same as the above problem, just with cats and tuna cans instead of tanks and gallons of water. Each cat gets 2/3 of a can.
"Two bags of bird seed are split among 5 parrots. What fraction of a bag does each parrot receive?"
2 bags divided between 5 parrots would be 2/5 of a bag for each parrot.
"Two apples are split among 3 people. How much of an apple does each person receive?"
Two apples split among 3 people - like the first 2 questions, this also equals 2/3.
"Three dogs each drink 2 cups of water. How many cups of water do the dogs drink in all?"
Three dogs EACH drink 2 cups of water means that the answer is 2*3=6 cups.
"Three cupcakes are divided among 2 children. How much of a cupcake does each child receive?"
Three cupcakes are split between 2 children - they will each get 3/2 of a cupcake, or 1 1/2.

Answer:
-10 or 25 (read my explanation)
Step-by-step explanation:
(-5)2
-5*2=-10
(Unless the 2 is supposed to be an exponent)
If it is supposed to be an exponent the answer is 25
(-5)^2

En una zona industrial se encuentran dos contenedores: en uno hay 198 litros de jugo de arándanos y en el otro hay 144 litros . Para su transporte se requiere guardar el jugo en el menor número de envases iguales. ¿Cuál debe ser la capacidad máxima de estos envases para que no sobre jugo?
Answer:
2 envases iguales de 171 litros
Step-by-step explanation:
Para calcular esto, primero necesitamos sumar los dos contenedores y cuantos litros de jugo tienen cada uno.
198 + 144 = 342 litros.
Ahora tenemos que calcular el numero minimo de envases. Si ya sabemos que es un numero par entonces lo podemos dividir en dos envases iguales sin que sobre...
342 / 2 = 171 litros
Finalmente, podemos ver que podemos dividir el jugo en 2 envases iguales de 171 litros

A study showed that the ratio of the number of people who get their news from print sources to the number of people who get their news from social media sources is 3:7. Based on the ratio, how many people in a town of 900 people get their news from social media sources?
Two classmates solved this problem and their work is shown below. Which classmate solved the problem correctly? Explain the error in the classmate who solved it incorrectly.
Answer:
270 = number who get news from print sources
630 = number who get news from social media
Step-by-step explanation:
Let 3x = number who get news from print sources
and 7x = number who get news from social media
Then 3x + 7x = 900
10x = 900
x = 90
3x = 3(90) = 270 = number who get news from print sources
7x = 7(90) = 630 = number who get news from social media
Check: 270/630 = 3/7 and 270 + 630 = 900
A solid cone of height 12cm and radius 9cm is recast into a solid sphere. Calculate the surface area of the sphere
Answer:
1017.8
Step-by-step explanation:
this is the formula 4πr2
hope this helps: )
Answer:
Step-by-step explanation:
Volume of cone = π9²⋅12/3 = 324π cm³
volume of sphere = 4πr³/3 = 324π
r = ∛243
surface area of sphere = 4πr² ≈ 155.8π

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
A family wants to rent a car to go on vacation. Company A charges $45.50 and 11c per mile. Company B charges $60.50 and 13c per mile. How much does Company B charge for x miles than company A?
Answer: Company B charges $(15.5+0.12x) more for x miles than company A.
Step-by-step explanation:
Let x = Number of miles.
Total charge = Flat charge + (charge per mile) x (Number of miles)
Given:
For Company A ,
Flat charge= $45
Charge per mile = 11 cents = 0.11 [ 1 dollar = 100 cents i.e. 1 cent = 0.01 dollar]
Total charge = 45+0.01x
For Company B,
Flat charge= $60.50
Charge per mile = 13 cents = 0.13
Total charge = 60.50+0.13x
Difference in charge = Charge for company B - Charge for company A
= 60.50+0.13x-(45+0.01x)
= 15.5+0.12x
Hence, Company B charges $(15.5+0.12x) more for x miles than company A.

Find the missing value to the nearest hundredth sin= 7/25
Answer:
16.26
Step-by-step explanation:
I am not completely sure what the problem is asking, but I believe that you are just supposed to take the inverse of sine. So, in your calculator, make sure it is in degrees mode, then usually you have to click the 2nd key and then sine. You use the inverse of sine when two sides are given, but you are not given the angle.
It should look like:
[tex]sin^{-1}(\frac{7}{25})[/tex], which is approximately 16.26.
Hopefully this is right, if not, please let me know. Good luck.

The table below shows X and Y values for the equation Y = X + 13
What is Y when X = 17?
Answer:
[tex]Y=30[/tex]
Step-by-step explanation:
[tex]Y=X+13[/tex]
If X = 17, you have to add that with 13 to get Y.
[tex]17(X)+13=30\\Y=30[/tex]

Find the percentage decrease.
Jesse has 158 quarters and nickels. The value of the collection is $19.10. How many of each coin does she have?
Answer:
102 nickels and 56 quarters
Step-by-step explanation:
Since the total amount of coins is 158, then...
q+n=158
Since the total amount of money is $19.10, and a quarter is 25 cents and a nickel is 5 cents, then...
0.25q+0.05n=19.10
Now that we have 2 equations and 2 variables, we can solve for this equation by solving the first equation for q and plugging it into the second equation.
q+n=158,
q=158-n
Plug into the other equation,
0.25(158-n)+0.05n=19.10
and solve for n
39.5-0.25n+0.05n=19.10
39.5-0.2n=19.10
-0.2n=-20.4
n=102
there are 102 nickels.
Now solve for quarters.
q+n=158
q+102=158
q=158-102
q=56
