answer the following table:)

Answer:

The area of the biggest circle is 254.47

Step-by-step explanation:

9 times 3.14 = 254.47

Step-by-step explanation:

Diameter of large = 12+6 = 18cm

A = πr^2

A= 254.47 cm^2

Length x width x height 4x4x4 so 64

E, D, and A.

well because it can be divide my 5.

Questions:

(a) What is a simplified expression for (x + y) – (x – y)?

(b) Carlotta thinks that [tex]3y + 5y^3[/tex] is the same as [tex]8y^4[/tex]. Which statement shows that it is NOT the same?

Answer:

[tex](x + y) - (x - y) =2y[/tex]

[tex]3y + 5y^3 \ne 8y^4[/tex]

Step-by-step explanation:

Solving (a):

Given

[tex](x + y) - (x - y)[/tex]

Required

Simplify

[tex](x + y) - (x - y)[/tex]

Open brackets

[tex](x + y) - (x - y) = x + y - x + y[/tex]

Collect Like Terms

[tex](x + y) - (x - y) = x - x+ y + y[/tex]

[tex](x + y) - (x - y) = y + y[/tex]

[tex](x + y) - (x - y) =2y[/tex]

Solving (b):

Given

[tex]3y + 5y^3[/tex] and [tex]8y^4[/tex]

Required

Which expression shows they are not the same

The expression that shows this is:

[tex]3y + 5y^3 \ne 8y^4[/tex]

Take for instance; y=2

Substitute 2 for y in [tex]3y + 5y^3 \ne 8y^4[/tex]

[tex]3*2 + 5*2^3 \ne 8*2^4[/tex]

Evaluate all exponents

[tex]9 + 5*8 \ne 8*16[/tex]

[tex]9 + 40 \ne 128[/tex]

[tex]49 \ne 128[/tex]

The above expression supports [tex]3y + 5y^3 \ne 8y^4[/tex]

Answer:

Step-by-step explanation:

1. 10^2+7^2=x^2

x=sqrt(149)

2. 21^2-19^2=x^2

x=sqrt(80)

3. This is all pythagorean theorem busywork, a^2+b^2=c^2 where c is the hypotenuse of the triangle.  I think from my examples you should be able to figure the rest out.

Answer:

X^2+13x+40=area

Step-by-step explanation:

So its

(x+8)*(x+5)

Now solve

Use FOIL

x^2+5x+8x+40

Now combine

x^2+13x+40

There you have it

Answer:

y = 4x - 9

Step-by-step explanation:

Same slope, so they're parallel

Answer:

about 11.5

Step-by-step explanation: i think this is right

Answer:

11.538%

Step-by-step explanation:

290 - 260 /260  x 100% = 11.538

Answer:180

Step-by-step explanation:

Since 15% of 400=60 and 40%=160 the total of this combined is 220. 400-220=180 which is the amount of purple marbles

Answer:

4x + 7y = 3365

x + y = 578

x = matinees

y = regular

Step-by-step explanation:

Given

$4 = matinees

$7 = regular

Total tickets = 578

Money collected = $3365

If one calls the amount of matinees that when "x" and the amount of regulars that went "y", then one can form the system;

4x + 7y = 3365

x + y = 578

Solving the system;

Multiply the second equation by (-4)

4x + 7y = 3365

-4x - 4y = -2312

Add the equations

4x + 7y = 3365

-4x -4y = -2312

3y = 1053

Inverse operations

3y = 1053

/3        /3

y = 351

x = 227

Answer:

I believe it's SAS, but I am not 100% sure. I say this because you see the angle then in between is a side then another angle

Answer:

[tex]44,826.72\ \text{pounds}[/tex]

Step-by-step explanation:

Given that,

The diameter of a hemispherical tank= 14 feet

Radius, r = 7 feet

water

Water weighs 62.4 pounds per cubic foot.

We need to find the total weight of the water in a full tank to the nearest pound.

The volume of the hemisphere is given by :

[tex]V=\dfrac{2}{3}\pi r^3\\\\V=\dfrac{2}{3}\pi \times (7)^3\\\\V=718.377\ \text{feet}^3[/tex]

If water weighs 62.4 pounds per cubic foot, it means

[tex]V=718.377\times 62.4\\\\V=44,826.72\ \text{pounds}[/tex]

So, the total weight of the water is [tex]44,826.72\ \text{pounds}[/tex].

Answer:

-2(y+4)-2y >8

-2y-8-2y>8

-4y-8>8

-4y<8+8          

When you move a number on the other side it changes the side then > will become <

-4y<16

-4y/-4<16/-4

y<-4

Answer:

C. corresponding angles

Step-by-step explanation:

I think this because 1 and 5 are on the same side and they're angles formed by the transversal line that cuts across

Answer: 4,12

Step-by-step explanation:

Bowl-O-Rama:

y = 2 + 2.50x

Bowling Pinz:

y = 4 + 2x

When you graph this, the solution is (4, 12). This represents that when you play 4 games for either company, both the prices will be the same, $12.

Answer:

$18.00

Step-by-step explanation:

Bowl-O-Rama: $4.50 times 4

Bowling Pinz: $6.00 times 3

Answer:

See below

Step-by-step explanation:

There are two ways to graph an equation.

1st Way:

We can use a graphing calculator. (See the attached file)

2nd Way:

We can take the values of x as 0, 1 , 2 (Or anything).

Then, We have to put the values of x in the equation to get the value of y accordingly.

According to these values, Plot the graph.

Also,

Slope = 5 / 6

y-intercept = 1

Answer: (-3, 4)

Step-by-step explanation:

The point at which both lines intersect is (-3, 4)

And since they intersect at ONE point, it just has one solution.
