There are 12 girls at a slumber party. 2/3 of the girls brought a sleeping bag. How many girls brought a sleeping bag?

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]

Answer:

c

Step-by-step explanation:

Answer:

$5

Step-by-step explanation:

Set up a system of equations

let b be the cost of a bow

let w be the cost of a roll of wrapping paper

This means that

[tex]5b + w = 10\\b + w = 6[/tex]

Subtract the two equations

[tex]5b + w = 10\\- (b + w = 6)\\4b = 4\\b = 1[/tex]

Plug this into the equation b + w = 6

1 + w = 6

w = 5.

This means the cost of a bow is $1 and the cost of a roll of wrapping paper is $5.

Answer:

28.3 m^2

Step-by-step explanation:

The formula to find the area of a circle is πr^2

r = radius (half of the diameter) = 3

3^2 = 9 so the area is 9π m^2

Rounded to the nearest tenth this equals about 28.3 m^2.

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:

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

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 (-∞, ∞).

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

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.

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)

Answer:

To calculate the sales tax that is included in a company's receipts, divide the total amount received (for the items that are subject to sales tax) by "1 + the sales tax rate". In other words, if the sales tax rate is 6%, divide the sales taxable receipts by 1.06.

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.

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
