Answer:

X is equal to 20

Step-by-step explanation:

Angles of a triangle equal 180.

110+x+x+30=180

2x+140=180

2x=40

x=20

If you input 20 as X back into the equation, then you can check that it is the right answer.

Answer:

Step-by-step explanation:

The steps are more or less the same, except for one new addition:

Divide the tens column dividend by the divisor.

Multiply the divisor by the quotient in the tens place column.

Subtract the product from the divisor.

Bring down the dividend in the ones column and repeat.

i dont know how to find the volume

Given:

A right triangle with legs 5 units and 6 units.

To find:

The measure of angle opposite of side whose length is 5 units.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Opposite}{Adjacent}[/tex]

Let [tex]\theta [/tex] be the missing angle. Then, for the given triangle,

[tex]\tan \theta=\dfrac{5}{6}[/tex]

[tex]\theta=\tan^{-1}\dfrac{5}{6}[/tex]

[tex]\theta=39.805571^\circ[/tex]

Round the value to the nearest degree.

[tex]\theta\approx 40^\circ[/tex]

Therefore, the measure of the required angle is 40 degrees.

Answer:

G. Heather rented a hotel for $110 a night plus $18 a night for valet parking

Step-by-step explanation:

A proportional relationship is one that has a constant ratio between two variables

y/x = Constant

From the given options, the one with a proportional relationship is option G.

The amount at which Heather rented a hotel = $110

The amount he pays for valet parking = $18

The total amount Heather pays a night = $110 + $18 = $128

The amount she pays for 2 nights = 2 × $128 = $256

Therefore, we have;

[tex]\begin{array}{cc}x&y\\1&128\\2&256\\3&384\end{array}[/tex]

From which we get;

y/x = 128/1 = 256/2 = 128 = Constant.

Answer:

Una expresión  es un grupo finito de términos algebraicos y símbolos matemáticos combinados en donde las letras se usan para representar números con valores desconocidos o imaginarios.

Una expresión consta de:

Coeficiente: que es el numero que no cambia o varia

Variable: representada por una letra y su valor cambia o fluctúa.

Para el enunciado, las variables son:

X= Nº de reproductores MP3

Y= Nº de reproductores DVD

Y las constantes son las ganancias por la venta de cada articulo

Ganancia de X = 35

Ganancia de Y= 15

La expresión que representa la ganancia por las ventas de MP3 y DVD, será:

G = 35X + 18Y

just took test and got it right

Answer:

1. 60 is his y-intercept

2. $82.11 in his account after 8 years

Answer:

The y-intercept of Jacob's graph is $60, which represents the initial amount of money he deposited into the account.

If Jacob doesn't deposit any additional money into the account, the amount of money he will have in eight years can be found by plugging in x=8 into the equation y = 60(1 + 0.04)^x and evaluating:

y = 60(1 + 0.04)^8

y ≈ $82.08

So the answer to the second question is that Jacob will have approximately $82.08 in the account after eight years, assuming he doesn't deposit any additional money into the account.

Hope this helps,
Ariana :)

Answer:

The volume of the cylinder is 3,080 cm^3

Step-by-step explanation:

Mathematically, we have the volume calculated as;

V = pi * r^2 * h

r = radius = 14 cm/ 2 = 7 cm (14 cm is the diameter and the radius is half the diameter)

h = height = 20 cm

Substituting these values;

V = 22/7 * 7^2 * 20

V = 22 * 7 * 20

V = 3,080 cm^3

Answer:

no real solutions

Step-by-step explanation:

- Rewrite equations:

y=3x−11;−3x+y=−13

Step: Solvey=3x−11 for y:

y=3x−11

Step: Substitute 3x−11 for y in−3x+y=−13:

−3x+y=−13

−3x+3x−11=−13

−11=−13(Simplify both sides of the equation)

−11+11=−13+11(Add 11 to both sides)

0=−2

Answer:

No solutions.

Answer:

Option A

Step-by-step explanation:

Out of 12 contestants, the judges will select either 3 or 4 contestant.

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_3[/tex]

[tex]220[/tex]

Number of groups that can be formed when judges pick three contestants

[tex]^{12}C_4\\495[/tex]

Number of more  groups that can be formed if the judges  pick four instead of three

[tex]= 495-220 = 275[/tex]

Hence, option A is correct
