Answer:75/6

Step-by-step explanation: Y is proportional to x so 12 is proportional to 5 so if y=30 then it will be 30*5/12=150/12=75/6

Answer:4, 9, 14, 19, 24, . ... 1, 3, 9, 27, 81, is a geometric sequence. ... 0, 2, 6, 12, 72, does not have a set number it is multiplied or divided by each time.

Step-by-step explanation:

thats all

Answer: D.

1, 3, 9, 27, 81, . . .

This problem can be done by process of elimination.

Notice that in our equation, our slope is positive.

In all these graphs, we have a negative slope.

Slope just describes how steep a line is.

The only graph that has a positive or upward slope is D.

So this is our answer.

Answer:

D

Step-by-step explanation:

The y-intercept (the value of y when x =0) of this graph is y = 1/3(0) +2. So, (0, 2) should be the y-intercept. By looking at the graph of D you can tell that at point x = 0, y = 2. Also, the equation is written in the slope-intercept form (y =mx + b) The slope of this line is 1/3. If you choose any two points from the line and calculate the rise/ run by using the slope formula or by directly counting the units, you will find that it is indeed 1/3.

Answer: #3: x=11

#4: x=2

Step-by-step explanation:

Answer:

Yes, y=1

Step-by-step explanation:

So, QT and ST are congruent (equal to each other)

So, we just set the values equal to each other too

9y=y+8

subtract y from both sides, and you get:

8y=8

divide both sides by 8 and you get:

y=8

Answer:

Your answers are:

B: 147 degrees

C: 33 degrees

Step-by-step explanation:

a straight line is 180 degrees.

And b is 147 degrees, so 180 - 147 is 33 degrees.

Step-by-step explanation:

32.75 + m =75

Answer:

3.86

Step-by-step explanation:

To solve this problem, we can use sine of the angle 75(which as a reminder, is opposite over hypotenuse):

sin(75)=x/4

x=4*sin(75)

If you plug that into a calculator, you get approximately 3.86.

The picture below shows how to set up the triangle.

Answer:

The coordinates of the points on the unit circle help us to find the tangent of each angle. As you can see with this equation, the tangent of an angle is equal to the y-coordinate divided by the x-coordinate. For each angle, start by dividing each y-coordinate by the x-coordinate to get the tangent of that angle.

Answer:

y = -0.5x – 11.5

so the slop is -1/2

this means it goes down by 1/2 every time

-0.5

Answer: 75%

Step-by-step explanation:

20+20+25+3+2+5=75

Total of 100 students

75/100=0.75

=75%

 The percentage of P(sports ∪ work) is equal to  75%.

We have given the table

we have to find the percentage of sports and work

Total=Work+sports

Therefore we have to add the values of work and sports

20+20+25+3+2+5=75

Total of 100 students

75/100=0.75

=75%

Therefore the percentage of P(sports ∪ work) is given by 75%.

Answer:

The surface area of a trapezoidal prism is the amount of area occupied by the surface of a trapezoidal prism. A trapezoidal prism is a three-dimensional solid that is made up of two trapezoids on opposite faces which are joined by four rectangles called the lateral faces. Like all three-dimensional shapes

Step-by-step explanation:

The area occupied by the surface of a trapezoidal prism is known as the surface area of a trapezoidal prism. Since the trapezoidal prism has a flat base, thus we can say that it has a total surface area and a curved surface area. The surface area of any three-dimensional geometrical shape is the sum of the surfaces of that enclosed solid which equals the areas of all of the faces. A trapezoidal prism has two trapezoidal faces four rectangular faces. Thus, the simple formula for calculating the surface area of a trapezoidal prism involves the area of the base, the perimeter of the base, and the slant height of any side of the prism. The surface area of any geometric figure is always measured in square units like cm2, m2, ft, or cubits2.

Answer: Total jam = 100kg

                 jams taken out on 2 occasions= 15  2/5kg    and  12  4/5 kg

                                                                       = 77/5  and  64/5

                    quantity of jam left in the container

                      = 100- (77/5 + 64/5)

                      =100- 141/5

                       = 100- 28.2

                       = 71.8 kg

pls put thanks as well pls mark this as the brainliest

as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.

[tex]\stackrel{f(x)}{y}~~ = ~~\cfrac{4x}{x-9}\implies \stackrel{\textit{quick switcheroo}}{x~~ = ~~\cfrac{4y}{y-9}}\implies xy-9x=4y\implies -9x=4y-xy \\\\\\ -9x=y(4-x)\implies \cfrac{-9x}{4-x}=y\implies \cfrac{9x}{x-4}=\stackrel{f^{-1}(x)}{y}[/tex]

how to test algebraically? well, for any (a,b) pair in f(x), its inverse will have another pair but (b,a), hmmm let's plug hmmm say

f(10) = 40, and f⁻¹(40) = 10.

we could plug more values in each, same pair will come up.

as far as testing them graphically, Check the picture below.

Step-by-step explanation:

For a, you have the theorem right above.

If B is 120 then D should be 180-120=60

Since C is 90, E should be 180-90=90

Use the same theorem for b as well

Answer:

1.

x=5

y=4

2.

y=19.8

x=4.2

3.

x=16

b=25/7

Answer:

  20.3 ft

Step-by-step explanation:

You want to know the height of a building if a 33 ft ladder reaches from the top of the building to a point 26 ft from the bottom of the building.

The geometry can be modeled by a right triangle with hypotenuse 33 ft and one leg of 26 ft. The other leg length (the building height) is found using the Pythagorean theorem.

  26² + h² = 33²

  h = √(33² -26²) ≈ 20.3 . . . . ft

The building is about 20.3 feet high.

Additional comment

This ladder makes an angle of about 38° with the ground. For ladder safety, an angle around 70° is usually recommended.
