Find the value of x, 110°, 4x+2, and if you can help with steps that would be great :,)

Answers

Answer:

x = 17

Step-by-step explanation:

The two angles with measures form a linear pair and are supplementary.

The measures of supplementary angles has a sum of 180°.

If you add the two given measures, the sum must equal 180°.

4x + 2 + 110 = 180

4x + 112 = 180

4x = 68

x = 68/4

x = 17

Answer:

[tex]\sin Y= \frac{XZ}{XY}[/tex]

[tex]\cos Y= \frac{YZ}{XY}[/tex]

[tex]\tan Y= \frac{XZ}{YZ}[/tex]

Step-by-step explanation:

Given

See attachment for triangle

Required

Find [tex]\sin, \cos[/tex] and [tex]\tan[/tex] of angle Y

For angle Y:

[tex]Opposite = XZ[/tex]

[tex]Adjacent = YZ[/tex]

[tex]Hypotenuse = XY[/tex]

The [tex]\sin[/tex] of an angle is calculated as:

[tex]\sin\theta = \frac{Opposite}{Hypotenuse}[/tex]

So:

[tex]\sin Y= \frac{XZ}{XY}[/tex]

The [tex]\cos[/tex] of an angle is calculated as:

[tex]\cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]

So:

[tex]\cos Y= \frac{YZ}{XY}[/tex]

The [tex]\tan[/tex] of an angle is calculated as:

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

So:

[tex]\tan Y= \frac{XZ}{YZ}[/tex]

What is the value of n?

Please help quick

Answers

Answer:

n = 15

Step-by-step explanation:

A straight line equals 180 degrees

Angle SWT is congruent to angle XWV meaning:

SWT (55 degrees) = XWV (55 degrees)

Set up an equation:

3n + 80 + 55 = 180

Combine like terms

3n + 135 = 180

Subtract both sides by 135 to isolate variable n

3n = 45

Divide both sides by 3 to isolate variable n

n = 15

a. 566
b. 567
c. 561
d. 573

Answers

Answer:

b. 567

Step-by-step explanation:

All you have to do is add the whole set, then divide by how many numbers it is.

573+569+566+561+566+566+568= 3969

3969/7= 567

There is 7 numbers in the set, so you add the numbers then divide by 7.

Answer: B is definitely the correct answer because you add up all the numbers then just divide.

Clarissa has a budget of $1,200 a month to spend for rent and food. She has already spent $928 this month. Which inequality represents the amount she can still spend this month and remain within her budget?
x greater-than 272
x less-than-or-equal-to 272
x less-than 272
x greater-than-or-equal-to 272

Answers

Answer:

1200-928 = 272 for the rest of the month Clarissa has to spend.

Step-by-step explanation:

So we don't want her to go over her budget so we wouldn't choose a greater than option for her so eliminate the first option and the last option. Now we just have the middle two. We want to keep it under 1200 but theres nothing wrong with spending that exact amount each month so I would pick x less than or equal to 272, since we can still equal the total of less than the total and not go over. Option 2 or B.

. Two planes are 1620 miles apart and are traveling toward each other. One plane is traveling 120 mph
faster than the other plane. The planes meet in 1.5 hours. Find the speed of each plane.

Answers

Answer:

Step-by-step explanation:

let the speed of one plane=x mph

speed of other plane=x+120 mph

x×1.5+(x+120)×1.5=1620

(x+x+120)×1.5=1620

(2x+120)×1.5=1620

3x+180=1620

3x=1620-180

3x=1440

x=480

speed of one plane=480 mph

speed of second plane=480+120=600 mph

HELP PLEASE! What’s the domain and range?

Answers

Answer:

Domain → (-∞, -1)∪(-1, ∞)

Range (-∞, ∞)

Step-by-step explanation:

Given function is,

[tex]\frac{f(x)}{g(x)}=\frac{x^2+2x-5}{2x+2}[/tex]

This function is not defined when the denominator is zero.

2x + 2 = 0

2x = -2

x = -1

Therefore, x = -1 is not in the domain of this function.

And the domain will be,

(-∞, -1)∪(-1, ∞)

For all values of x (except x = -1) we get some output values (value of [tex]\frac{f(x)}{g(x)}[/tex]).

Therefore, range of the function will be (-∞, ∞).

The point g (2,2) is translated 3units to the right and 4units up what are the coordinates of this resulting point, g?

Answers

Answer:

(5,6)

Step-by-step explanation:

Generally, is the coordinate (x,y) is translated right by a units and up by b units, the resulting coordinate wil be;

g(X, Y)  = (x+a, y+b)

To the right is along the positive x axis while up is along the positive y axis

Given a = 3 and b = 4

g(X,Y) = (2 + 3, 2 + 4)

g(X, Y) = (5, 6)

Hence the resulting coordinate of g is (5,6)

How much more did Leroy pay than Cora?​

Answers

Answer:

Leroy paid 49.07 more than Cora.

Step-by-step explanation:

Let LeRoy's bill be x

Let Cora's bill be y

3*y - 8.59 = x        (1)

x + y = 68.29        (2)

Substitute the value of x in (1) into the value of x in (2)

3y - 8.59 + y = 68.29          Combine the ys

4y - 8.59 = 68.29                Add 8.59 to both sides

   + 8.59     8.59

4y = 76.88                           Divide by 4

4y/4 = 76.88/4

y = 19,22

x + y = 68.29                      Substitute 19.22 for y

x + 19.22 = 68.29               Subtract 19.22 from both sides

  - 19.22   -19.22

x =              49.07

A clock has a diameter of 16 inches. Which measurement is closest to the area of the clock in square inches? 804.25 in2 50.27 in2 25.13 in2 200.96 in2

Answers

Answer:

200.96 in2

Step-by-step explanation:

Area of a circle = nr²

n = 3.14

r = radius

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

A radius is half of the diameter

diameter = 2r

radius = 16 inches / 2 = 8 in

Area = 3.14 x 8² =  200.96 in²
