Hi does anyone wanna do a math homework assignment? it involves volume and algebra (I'm in alg2/trig)
[tex]\huge\bold\green{Answer:-}[/tex]
Area. The amount of space covered by a two-dimensional object; the amount of carpet you'd need to cover a floor would depend on the floor's area.
Perimeter. The distance around a two-dimensional object; the amount of fence you'd need to surround your yard equals the perimeter of your yard. (The perimeter of a circular object is called the circumference.
Volume. The amount of three-dimensional space inside an object; the amount of liquid inside a soda can represents the can's volume.
Surface area. Measures the amount of "skin" needed to cover a three-dimensional object, neglecting its thickness; the amount of siding you'd need to completely cover a house represents the surface area of that house's walls.
Description Formula Variables
Area of a rectangle A = l · w l = length, w = width
Perimeter of a rectangle P = 2(l + w) l = length, w = width
Area of a circle A = r2 r = radius of circle
Circumference of a circle C = 2r r = radius of circle
Volume of a rectangular solid V = l · w · h l = length, w = width, h = height
Volume of a cylinder V = r2h r = radius; h = height
Surface area of a cube SA = 6l2 l = length of side

A team of players are planning to prepare a t-shirt for their next season of games. The team has 13 members and each member will have 2 t-shirts. (a)If a t-shirt costs Rs. 375, what will be the total cost of the t-shirts for the team?(b)A sponsor agrees to pay Rs. 7020 out of the total cost of the t-shirts. The balance amount will be paid by each player. How much will be paid by each player?
Answer:
Rs. 210Step-by-step explanation:
Given that a t-shirt cost Rs. 375,
then 2 t-shirt will cost Rs. 375*2
=Rs.750
a. the total cost will be
13*750
=Rs.9750
b. a sponsor pays Rs.7020
there will be a deficit of
9750-7020
=2730
since there are 13 players each player will pay
2730/13
Rs. 210
A kilogram of potatoes cost $25.A dozen bananas cost $40.
a) Write an algebraic expression for the total cost of n kilograms of potatoes and one dozen bananas.
b) Evaluate your expression to determine the cost of 15kg of potatoes and one dozen bananas
Answer:
a) T = 25n + 40
b) T = $415
Step-by-step explanation:
The total cost of 'n' kilograms of something can be expressed as 'n' multiplied by the cost, since it is a constant cost per unit. Therefore the price for n kg of potatoes can be expressed as 25n. We are also told that a dozen bananas cost $40, so our expression is the cost of potatoes added to the cost of bananas. So, is we use 'T' for total cost, our expression will look like this:
T = 25n + 40
Now we can use this expression to find the cost of 15kg of potatoes and the same amount of bananas. We can do this by simply substituting the given amount for n:
T = 25(15) + 40
T = 375 + 40
T = $415
The cost of 15kg of potatoes and one dozen bananas is $415.

If α , β are roots of x2 + 5x + a =0 and 2α + 5β = -1 then α is equal to _____?
9514 1404 393
Answer:
-8
Step-by-step explanation:
If α and β are roots of x^2 +5x +a = 0, then we must have ...
(x -α)(x -β) = x^2 +5x +a
x^2 -(α+b)x +αβ = x^2 +5x +a
Then ...
α + β = -5
Together with the other relation between the roots, we have a system of equations in α and β.
Using the above to write an expression for β, we get ...
β = -α -5
Substituting this into the given relation, we have an equation for α:
2α +5(-α -5) = -1
-3α -25 = -1 . . . . . . eliminate parentheses
-24 = 3α . . . . . . . . add 3α +1
-8 = α
The root α is equal to -8.
You add 4 drops of food coloring to 2 cups of white frosting and get the orange frosting above. Francisco wants his frosting to be the same color as yours, but he has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add.
Answer:
Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting
Step-by-step explanation:
4 drops of food coloring to 2 cups of white frosting and get the orange frosting.
He has 5 cups of white frosting. He doesn't know how many drops of orange food coloring to add
Let x = drops of food coloring he will add
Drops of food coloring : cups of white frosting
4 : 2 = x : 5
4 / 2 = x / 5
Cross multiplication
4 * 5 = 2 * x
20 = 2x
Divide both sides by 2
x = 20 / 2
= 10
x = 10 drops of food coloring
Therefore, Francisco will add 10 drops of food coloring to 5 cups of white frosting and get the orange frosting

A whole number k is greater than 3. Which of the following is true about k/3?
Answer:
D) It is greater than 1.
Step-by-step explanation:
Since k is greater than 3, it could not be between 0 and 1/3 and also could not be between 1/3 and 1
We also know that it is not equal to 1 because it is greater than 3.
Therefore, it is greater than 1.
A neon light flashes five time every 10 seconds. show that the lighy flashes 43200 tines in one day.
Step-by-step explanation:
There are 60 * 60 * 24 = 86400 seconds in a day
if the light flashes 5 times every 10 seconds, that means it flashes once every 2 seconds.
It follows the flashes in a day are 86400 / 2 = 43200
Jimmy sells cookies in bags of dozen cookies for $4.50. If the cost varies directly to the number of
cookies, how much would it cost for a bag containing 30 cookies?
Answer:
I'm pretty sure it would cost $11.25 since 6 cookies would be $2.25 if you divide the amount for a dozen in half. I hope it was right!

The owners of a golf course hired a company to determine how many squirrels were living on their property. First, the company put marks on 22 squirrels. Later, the company returned and counted a total of 220 squirrels, of which 11 were marked. To the nearest whole number, what is the best estimate for the squirrel population?
Answer:
Squirrel population is 440 squirrels.
Step-by-step explanation:
It is given that there are 22 squirrels are marked.
Later the company returned and counted a total of 220 squirrels of which are marked were 11.
So, we can set up proportional equation to find the squirrel population.
Let squirrel population is x.
We can set up proportional equation as
[tex]\frac{11}{220}=\frac{22}{x}[/tex]
Cross multiply
11 x=4840
Divide both sides by 11
x=440
Best estimate is 440.

Alyssa’s lemonade recipe calls for 9 lemons for every 2.5 gallons of water. Brian’s recipe calls for 12 lemons for every 4 gallons of water. Whose lemonade will require more water if they each use 36 lemons? . can you help me
Answer:
Alyssa’s lemonade recipe
Step-by-step explanation:
→ Work out how much lemons is needed per gallon for Alyssa’s lemonade recipe
9 lemons = 2.5 gallons
(÷ 2.5) = (÷ 2.5)
3.6 lemons = 1 gallon
→ Work out how much lemons is needed per gallon for Brian’s lemonade recipe
12 lemons = 4 gallons of water
(÷ 4) = (÷ 4)
3 lemons = 1 gallon of water
→ Now compare
Alyssa’s lemonade recipe ⇒ 3.6 lemons = 1 gallon
Brian’s lemonade recipe ⇒ 3 lemons = 1 gallon of water
Brian's lemonade recipe requires more water.
Alyssa uses 10 gallons of water for 36 lemons. Brian uses 12 gallons of water for 36 lemons. Therefore Brian's lemonade recipe requires more water.

Tonya wrote the equation below which solves for x.
x = 150 minus 6 y
Which equation is equivalent to Tonya’s equation?
x + 150 = 6 y
x + 6y = 150
2x + 3y = 75
2 x minus 3 y = 75
Given parameters:
x = 150 minus 6 y
Interpreting this gives;
minus = subtraction = -
x = 150 - 6y
Now bring the variables together;
x + 6y = 150
The option that matches with this equivalent.
The other choices are wrong;
a, x + 150 = 6 y
x - 6y = 150 wrong
c. 2x + 3y = 75 mulitply through by 2;
2(2x + 3y) = 2(75)
4x + 6y = 150 wrong
d. 2x - 3y = 75
Multiply by 2;
2(2x -3y) = 2(75)
4x - 6y = 150
Answer:
x+6y = 150 (B)

Help me with (-6,-7);y=-4x+1
Answer: y=-4x-31
Step-by-step explanation:
To find a ling that is parallel to the given line and passes through the given point, we need to use the given point. We know that the slope MUST stay the same because parallel lines NEVER touch. All we have to do is plug in the point and find the y-intercept.
-7=-4(-6)+b [multiply]
-7=24+b [subtract both sides by 24]
b=-31
Now, we know that y=-4x-31 is the equation.

Answer:
Add -3+8
Step-by-step explanation:
You would do this first because it is in the brackets. Usually you would do (*) first but those are just there because the 4 is negative and if they were not there it would get confusing and look like this::[-3+8]--4. So the next step would be the [*].
HOPE THIS HELPS!!!
Answer:
Use PEMDAS
Step-by-step explanation:
Parenthesis, If there are none move on to exponents if there are no exponents move to multiplication. No multiplication? use division. If you dont see division use addition and lastly if there is no addition use subtraction. In the equation, it looks like you have to make the -3 and 8 positive. So, since the -4 is in the parenthesis(P) multiply(M) 4 by 3 and 8 once the three is positive. So your final answer would be either C or D
