Answer:

C 4 /x^2

Step-by-step explanation:

20x / 5x^3

First divide the numbers

20/5 = 4

Then divide the variable

x/x^3  = x/ xxx  = 1/ xx  = 1/x^2

We are left with

4/x^2

The angles that make a straight line are called linear pair of angles.

Given are two adjacent angles.

Two adjacent angles that make a straight line are called linear pair of angles.

Answer:

55

Step-by-step explanation:

Since this is an isosceles triangle, the angles at the bases of the identical legs must be equal

<A = <C

3x+40 =x+50

Subtract x from each side

3x-x+40 = x+50-x

2x +40 = 50

Subtract 40 from each side

2x+40-40=50-40

2x = 10

Divide each side by 2

2x/2=10/2

x = 5

We want to find <A

3x+40

3(5)+40

15+40

Answer:

He gets paid $80 each weekend, and a 15% with tips.

you would need to figure out the tips, by taking the $725 and timesing it by .15 for the percent.

which would be 108.75

you would now take 108.75 and add 80 to get what he made that weekend.

108.75+80 = 188.75 dollars

Answer:

a) 2

b) [tex]\frac{4x}{y}[/tex]

Step-by-step explanation:

a) [tex]\frac{\sqrt{500} }{\sqrt{5} }[/tex]

We can rewrite 500 as 100*5 and 100 is [tex]10^2[/tex] causing the 10 to come out of the root.

[tex]\frac{10\sqrt{5} }{\sqrt{5} }[/tex]

Rationalize.

[tex]\frac{10\sqrt{5} }{\sqrt{5} }*\frac{\sqrt{5} }{\sqrt{5} } =\frac{10}{5}=2[/tex]

----------------------------------------------------------------------------

b) [tex]\frac{\sqrt{48x^3} }{\sqrt{3xy^2} }[/tex]

48 can be rewritten as 6*8 and 8 can be rewritten as [tex]2^2*2[/tex]

[tex]\frac{\sqrt{6*2^2*2x^3} }{\sqrt{3xy^2} }[/tex]

[tex]\frac{2\sqrt{6*2x^3} }{\sqrt{3xy^2} }[/tex]

[tex]\frac{2\sqrt{12x^3} }{\sqrt{3xy^2} }[/tex]

12 can be rewritten as 4*3 and 4 can be rewritten as [tex]2^2[/tex]

[tex]\frac{2\sqrt{2^2*3x^3} }{\sqrt{3xy^2} }[/tex]

[tex]\frac{2*2\sqrt{3x^3} }{\sqrt{3xy^2} }[/tex]

[tex]\frac{4\sqrt{3x^3} }{\sqrt{3xy^2} }[/tex]

[tex]x^3[/tex] is the same as [tex]x^2*x[/tex] causing x to come out of the root, as well as y.

[tex]\frac{4x\sqrt{3x} }{y\sqrt{3x} }[/tex]

Rationalize

[tex]\frac{4x\sqrt{3x} }{y\sqrt{3x} }*\frac{\sqrt{3x} }{\sqrt{3x} } =\frac{4x*3x}{y*3x} =\frac{12x^2}{3xy}=\frac{4x}{y}[/tex]

Answer:

- 18x + 32

Step-by-step explanation:

Given

- 2x - 4(4x - 8) ← distribute parenthesis

= - 2x - 16x + 32 ← collect like terms

= - 18x + 32

Answer: 242.7 square inches

Step-by-step explanation:

Hi, to answer this question we have to apply proportions:

The first model has a height of 5 inches and a surface area of 80.9 square inches:

The proportion is : height/ surface area= 5 in / 80.9 in2

For a height of 15 inches

15 in/ x in2

So:

5/80.9 = 15/x

x= 15/ (5/80.9 )

x= 242.7 square inches

Answer:

Triangle B

Step-by-step explanation:

you square both of your smallest sides, then you add them together and they should equal your largest side squared.

Answer:

Step-by-step explanation:

We solve this using the Pythagorean theorem: a² + b² = c²

Triangle A: 10, 12, 15

10² + 12² = 15²

100 + 144 = 225

244 ≠ 225 ❌

NOT A RIGHT TRIANGLE! ❌

Triangle B: 3, 4, 5

3² + 4² = 5²

9 + 16 = 25

25 = 25 ✅

RIGHT TRIANGLE ✅

Triangle C: 7, 8, 9

7² + 8² = 9²

49 + 64 = 81

113 ≠ 81 ❌

NOT A RIGHT TRIANGLE! ❌

Triangle D: 5, 12, 16

5² + 12² = 16²

25 + 144 = 256

169 ≠ 256 ❌

NOT A RIGHT TRIANGLE! ❌

The function to represent this situation is A = P( NR+1 ) and the amount in 2016 is $704.

"Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time. In simple interest, the principal amount is always the same".

For the given situation,

Principle, P = $200

Rate of interest, R = 7% = 0.07

Number of years from 1980 to 2016, N = 36

The total amount in 2016 can be modeled as the equation,

[tex]A=P(NR+1)[/tex]

⇒ [tex]A = 200[(36)(0.07)+1][/tex]

⇒ [tex]A=704[/tex]

Hence we can conclude that the function to represent this situation is     A = P( NR+1 ) and the amount in 2016 is $704.

Answer:54 pi

Step-by-step explanation:

Answer:

No solution

Step-by-step explanation:

18x - 5 < 3(6x - 2)       Distribute the 3 to (6x - 2)

18x - 5 < 18x - 6

-18x        -18x               Subtract 18x from both sides

-5 < -6                         There is no solution because -5 is not less than -6.

Answer:

P(Both) = 781/10000

Solution:

P(T) = 71/100

P(6) = 11/100

P(Both) = P(T) * P(6)

(Both) = 71/100 * 11/100

P(both) = (71 * 11) / 10000

P(Both) = 781/10000

T = 71 times

5 being rolled = 11

Substitution and solution.

P(T) = 71/100

P(6) = 11/100

P(Both) = P(T) * P(6)

P(Both) = 71/100 * 11/100

P(both) = (71 * 11) / 10000

P(Both) = 781/10000
