Answer:

D. x = 18 cm , y = 9

Step-by-step explanation:

With reference angle 60

perpendicular (p) = 9[tex]\sqrt{3}[/tex]

base(b)= y

hypotenuse (h) = x

Then

sin 60 = p/h

[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]

x = 18

Now

cos 60 = b/h

1/2 = y/18

y = 9

Hope it will help :)

Answer:

it's answer is

D. = 18 and y = 9

Answer:

B (for question 7)

Step-by-step explanation:

To find the slope, we use the equation [tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].

m = (-4+1)/(7+2) = -3/9 = -1/3

Since B is the only option that would give a slope of -1/3, B must be the answer.

(you can use this same method for question 8)

Answer:

120

Step-by-step explanation:

all angles of a triangle add up to 180. 180-15-45= 120.

:D

brainliest pls

Given :

Measure of an angle = 15°

Measure of the second angle = 45°

Let the measure of the third angle be x.

We know that :

▪︎Sum of all angles of a triangle = 180°[angle sum property]

Which means :

[tex] =\tt 15 + 45 + x = 180[/tex]

[tex] =\tt 60 + x = 180[/tex]

[tex] =\tt x = 180 - 60[/tex]

[tex]\hookrightarrow\color{plum}\tt \: x = 120°[/tex]

Thus, the measure of the third angle = 120°

Since the sum of all these angles is equivalent to 180°[15+45+120=180] we can conclude that we have found out the correct measure of the third angle.

Therefore, the correct option is (C) 120

Given:

Dustin wants a new pair of shoes that cost $40.

His mom pays 75% of the cost and dustin pays 25%.

To find:

How much do they each pay?

Solution:

We have,

Total cost of shoes = $40

His mom pays 75% of the cost.

[tex]\text{Mom pays}=\dfrac{75}{100}\times 40[/tex]

[tex]\text{Mom pays}=\dfrac{3}{4}\times 40[/tex]

[tex]\text{Mom pays}=30[/tex]

Dustin pays 25% of the cost.

[tex]\text{Dustin pays}=\dfrac{25}{100}\times 40[/tex]

[tex]\text{Dustin pays}=\dfrac{1}{4}\times 40[/tex]

[tex]\text{Mom pays}=10[/tex]

Therefore, Dustin pays $10 and his mom pays $30.

Answer:

15x - 6

Step-by-step explanation:

To solve this, Given the expression 12 x + 3 ( x − 2 )

To simplify, expand

12 x + 3 * x −3 * 2

Knowing that

- * + = -

then the expression becomes

= 12 x + 3x - 6

= 15x - 6

The expression given is equivalent to 15x - 6

i got you just tell me the question

Step-by-step explanation:

Answer:

It would change the y-intercept, so if it turned into a 3, the slope would just go higher at the beginning.

The graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

The equation y = 2ˣ⁻⁴ - 3 is an exponential function that has been shifted 4 units to the right and 3 units down from the basic exponential function y = 2ˣ.

If we change the -3 to a 3, we get the new equation:

y = 2ˣ⁻⁴ + 3

This new equation represents the original exponential function shifted 4 units to the right and 3 units up.

Therefore, the graph of the new equation y = 2ˣ⁻⁴ + 3 will have the same shape as the original graph, but it will be shifted 4 units to the right and 3 units up.

wow this waz ez

Answer:

see explanation

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 3x - 2 ( add 2 to both sides )

y + 2 = 3x ( divide both sides by 3 )

[tex]\frac{y+2}{3}[/tex] = x

change y back into terms of x with x = [tex]f^{-1}[/tex] (x)

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+2}{3}[/tex]

To evaluate [tex]f^{-1}[/tex] (13) substitute x = 13 into [tex]f^{-1}[/tex] (x) , that is

[tex]f^{-1}[/tex] (13) = [tex]\frac{13+2}{3}[/tex] = [tex]\frac{15}{3}[/tex] = 5

Answer: 62

Step-by-step explanation:

First and foremost, we have to calculate the volume of the box which will be:

= 2 2/3 × 3 1/3 × 2 1/3

= 8/3 × 10/3 × 7/3

= 560/27

= 20 20/27

The number of 1/3 inch cubes needed to fill the box will then be:

= 20 20/27 ÷ 1/3

= 560/27 ÷ 1/3

= 560/27 × 3

= 560/9

= 62 2/9

Therefore, 62 boxes can be filled
