-4(2x+9)+3x=6-4(x-3)

Answer:

1. A. 66 cubic inches.

2. A. 151,410,000

Step-by-step explanation:

For number one: Multiply 3 x 4 and that will give you 12 then multiply that by 11 and that will also give you 132. Lastly, divide 132 by 2 and it will get you 66 cubic inches.

For Number two: Multiply 420 by 721,000 and that will give you 302,820,000.

Once you have that, divide it by 2 and will give you 151,410,000.

Answer:

210

Step-by-step explanation:

Step 1: 6 rows and 6 columns each side so 6*6=36

Step 2: we have 6 sides so 36*6=216 cubes

Step 3: substract 6 cubes from the total since each row and column shares the same cube 216-6=210 cubes

The total number of unit cubes is A = 210 cubes and volume is V = 216 units³

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the height of the rectangle be = 6 units

Let the length of the rectangle be = 5 units

And , let the width be = 7 units

So , Volume of Rectangle = Length x Width x Height

V = 6 x 5 x 7

V = 210 units³

Hence , the number of unit cubes is A = 210

Answer:

960 cm²

Step-by-step explanation:

Volume = height x length x width

Volume = 16 x 12 x 10

Volume = 1920 cm²

Since this prism is half

Volume = 1/2 ( 1920)

Volume = 960 cm²

Answer:

192 km²

Step-by-step explanation:

Surface Area of the triangular prism = 2(Base Area) + Perimeter of Base*height of the prism

✔️Base Area = ½*bh

b = 6 km

h = 8 km

Base area = ½*6*8 = 24 km²

✔️Perimeter of base = 6 + 8 + 10 = 24 km

✔️Height of prism = 6 km

Plug in the values into the equation:

Surface area = 2(24) + 24*6 = 48 + 144

Surface area = 192 km²

You are doing good I would say! Your average grade would be a B- Or just a normal B Somewhat around there.

Step-by-step explanation:

I hope this helps you and good luck! Bye!

Grade scale:

A → 100-90

B → 89-80

C → 79-70

D → 70

F <70

That being said to see your grade, add all your grades up then divide it by how many grades you have.

That being said, if you add all your grades then divide it by how many grades you have, you should have a 85.6 as your average.

Hence, your average is a B.

Answer:

2/3

Step-by-step explanation:

REmember that the slope of a line is y/x. To find this, we must use the formula:

y2-y1/x2-x1=y/x

So this is -1 - -7/4- -5. The  -1 -- 7 is actually -1+7. This is 6, meaning y equals 6.

The x is 4 - - 5 is actually 4+5. This is 9, meaning x is equal to 9.

We can now write this as y/x. This would be 6/9.

Once we simplfy this, we get 2/3.

Answer:

23 boxes of toys are being stored.

Step-by-step explanation:

There is a fixed cost of $1200 a month for rent and a variable cost of $5 per box of toys that are stored

This means that for x boxes of toys stored, the total cost is of:

[tex]C(x) = 1200 + 5x[/tex]

If the total cost for this month was $1315, how many boxes of toys are being stored?

This is [tex]x[/tex] for which [tex]C(x) = 1315[/tex]. So

[tex]C(x) = 1200 + 5x[/tex]

[tex]1315 = 1200 + 5x[/tex]

[tex]5x = 115[/tex]

[tex]x = \frac{115}{5}[/tex]

[tex]x = 23[/tex]

23 boxes of toys are being stored.

Will be reveled in part B.

Step-by-step Part A

Using O P N Chart for the profits of $500

O P N represent Original, Part Percent and New original.

O $500 ║100%

P   $410║-18%

N $90   ║82%

I got $410 which is my part percent by subtracting the original by the New original. (500 - 90 = 410)

Now to solve for the part percent and New original which we will know how much money would be given to charity?

Solving for part percent

Part percent x org = Part

(X) x 500 = 90

500x = 90

500      500

x = 0.18 =  18%.

If they sell $500  worth of calculators and donates $90 to charity they are left with $410 and they gave the charity 82%

Part B:

O: $90   ║ 100%

P:   $110  ║-18%

N: $200  ║82%

So this tells me that the charity recived $110.

Answer:

Step-by-step explanation:

Given function is,

[tex]y=(\frac{1}{2})^x[/tex]

In the given exponential function,

Base of the function = [tex]\frac{1}{2}[/tex]

By the property of an exponential function,

1). If the base is between 0 and 1, function will be a growth function.

2). If the base is greater than 1, function will be a decay function.

Therefore, given function is a decay function.

Input-output table,

x             -2                -1               0                1                 2

y      [tex](\frac{1}{2})^{-2}=4[/tex]     [tex](\frac{1}{2})^{-1}=2[/tex]     [tex](\frac{1}{2})^{0}=1[/tex]   [tex](\frac{1}{2})^1=\frac{1}{2}[/tex]      [tex](\frac{1}{2})^2=\frac{1}{4}[/tex]

By plotting these points we can get the graph of the function.
