Find the perimeter of the triangle

(21-x) in.
(2x - 3) in.
(x + 5) in.

Answer:

3x^2 - 12x·y^2 - 9y^2·y^4

Step-by-step explanation:

Apply the distributive property of multiplication here.

x times (3x - 3y^2) is 3x^2 - 3x·y^2.

3y^2 times (3x - 3y^2) is 9x·y^2 - 9y^2·y^4.  

Thus, the desired product of the given binomials is the sum of the above results:

3x^2 - 3x·y^2 - 9x·y^2 - 9y^2·y^4

which shortens to   3x^2 - 12x·y^2 - 9y^2·y^4

Answer:

Step-by-step explanation:

Part 1

P(z < -1.45)

Using the z score table

P =

Part 2

We solve using z score formula

z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

a) P(X >52)

x = 52

Mean = 60

Standard deviation = 8

z = 52 - 60/8

z = -1

P-value from Z-Table:

P(x<52) = 0.15866

P(x>52) = 1 - P(x<52) = 0.84134

b) P(48 < x < 64)

Answer:

5/2

Step-by-step explanation:

Tammy has 4 songs

For each of the songs, the time spent is 5/8 minutes

Therefore the total time spent ca be calculated as follows

= 4 × 5/8

= 20/8

= 5/2

Hence the total time spent is 5/2

Answer: 2.5

Step-by-step explanation: 4* 5/8 = 20/8 20/8= 2 4/8  2 4/8 = 2 1/2

2 1/2= 2.5

Answer:

126.0000 square units

Step-by-step explanation:

Answer:

1/4

Step-by-step explanation:

Coin sample Space = {H, T}

Spinner sample space = {1, 2, 3, 4, 5, 6, 7, 8}

Probability that coin lands on head :

P(H) = 1 /2

Probability that spinner lands on odd number :

Odd numbers = {1, 3, 5, 7} = 4

P(spinner lands on odd) = 4 / 8 = 1/2

Hence, probability that the coin will land on heads and the spinner will land on an odd number = (1 /2 * 1/2) = 1/4

Answer:

C) 99 + 3x

Step-by-step explanation:

Since it's always going to cost 99, it'll stay like that since it's a constant

Since it's 3 PER person, that means 3 will have a variable: 3x

[tex]904.32[/tex]

Step-by-step explanation:

[tex]\frac{4}{3}\cdot \:3.14\cdot \:6^3[/tex]=[tex]904.32[/tex]

The volume of a sphere is [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

Answer:

Each side is 5 units long

Step-by-step explanation:

Since the opposite angles are equal then x + 2 = 3x - 4

So solve for x: so  4+2 = 3x - x

6 = 2x

3 = x

So one side is x + 2 = 3 + 2 = 5

The other side is 3x - 4 = 3(3) - 4 = 9-4 = 5

Answer:

[tex]A=\dfrac{121}{8}\ in^2[/tex]

Step-by-step explanation:

There are 44 rectangular stickers

Length of each sticker= (1/2) inch

The width of each sticker = (11/16) inch

We need to find the area of the all stickers. The area of a rectangle is given by :

[tex]A=l\times b\\\\A=44\times \dfrac{1}{2}\times \dfrac{11}{16}\\A=\dfrac{121}{8}\ in^2[/tex]

So, the area of all stickers is equal to [tex]\dfrac{121}{8}\ in^2[/tex].

Answer:

The correct answer is C. That problem best represent x - 15 =60.

Answer:

C

Step-by-step explanation:

So lets look at the first equation.

This would represent 60-15=x

This is because 60 shells minus 15 shells she gave away.

Next is B, whihc is also 60-15=x

This is because Mr yungs brother is 60 years old and mr yung is 15 years younger.

Next is c, whihc is 60+15=x

This is because they had 60, gave 15 already, and want to find out what they started with.

FInally we are left with d.

This is 15+x=60

Well...none of those look like x-15=60

But lets go back to c:

60+15=x

Lets try to rwwrite this.

Subtract 15 from both sides, and you get:

60=x-15

Just make this proper by putting the x-15 before the 60:

x-15=60

That looks like x-15=60

Now we know our answer!

C
