You roll a number cube one time.
What is the probability of rolling a 5 or a 8?

Answer:

RV = 15, ∠ VUR = 48°

Step-by-step explanation:

The diagonals of a rectangle are congruent , so

RT = SU , that is

5x - 10 = 4x - 2 ( subtract 4x from both sides )

x - 10 = - 2 ( add 10 to both sides )

x = 8

Then

RT = 5x - 10 = 5(8) - 10 = 40 - 10 = 30

The diagonals bisect each other , then

RV = 0.5 × 30 = 15

---------------------------------------------------------------

∠ RVU = ∠ svt = 84° ( vertical angles )

RV = UV ( diagonals are congruent and bisect each other )

Then Δ RVU is isosceles with base angles congruent , then

∠ VUR = [tex]\frac{180-84}{2}[/tex] = [tex]\frac{96}{2}[/tex] = 48°

Answer:

75

Step-by-step explanation:

mean = average so add up all your numbers, then divide by the amount of numbers so

46 + 56 + 64 + 64 + 72 + 76 + 77 + 82 + 94 + 96 + 99 = 826

826 ÷ 11 = 75.09 (about)

Answer:

C

Step-by-step explanation:

The reason we shall be choosing the graph c is as a result of the plot type

Now, looking at the inequalities, we can see that the second inequality does not have an equal to assigned

Whenever we want to plot this kind of inequality, we are going to use the dotted line in place of the thick line used in cases where we have the equal to assigned to the inequality

So, what this looks like is that only the option C has the correct representation of the dotted line and thus represents our answer

Answer: w = 2

Explanation: To find the slope of a line, we use the formula y = mx + b, where m is the slope and b is the y-intercept. Since there is a variable, w, we can use this formula: m = 7 + w.

We know that m, or the slope of the line, is 9. If we substitute the value of 9 into that equation... we should get 9 = 7 + w.

It's simple mathematics from here.

7 plus what is 9?? 2. That's your answer. If you need help with slope-intercept and rate of change WITHOUT variables (besides x and y, of course), feel free to let me know!!

Where did I get that 7?

Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.

We will be using this formula: y - y₂ = m(x - x₁)

This equation is useful when we know:

and we want to find the other point.

(x₁, y₁) is the known point. In our example, it's (-7,-7).

(x, y), sometimes written as (x₂,y₂), is (-6, w) and represents the missing coordinate.

EXAMPLE (SEE IMAGE):

slope (m) = 3

y − y1 = m(x − x1)

We know m, and also know that (x1, y1) = (3,2), and so we have:

y − 2 = 3(x − 3)

That is a perfectly good answer, but we can simplify it a little:

y − 2 = 3x − 9

y = 3x − 9 + 2

y = 3x − 7

Given:

The height of a golf ball is represented by the equation:

[tex]y=x-0.04x^2[/tex]

To find:

The maximum height of of Anna's golf ball.

Solution:

We have,

[tex]y=x-0.04x^2[/tex]

Differentiate with respect to x.

[tex]y'=1-0.04(2x)[/tex]

[tex]y'=1-0.08x[/tex]

For critical values, [tex]y'=0[/tex].

[tex]1-0.08x=0[/tex]

[tex]-0.08x=-1[/tex]

[tex]x=\dfrac{-1}{-0.08}[/tex]

[tex]x=12.5[/tex]

Differentiate y' with respect to x.

[tex]y''=(0)-0.08(1)[/tex]

[tex]y''=-0.08[/tex]

Since double derivative is negative, the function is maximum at  [tex]x=12.5[/tex].

Substitute [tex]x=12.5[/tex] in the given equation to get the maximum height.

[tex]y=(12.5)-0.04(12.5)^2[/tex]

[tex]y=12.5-0.04(156.25)[/tex]

[tex]y=12.5-6.25[/tex]

[tex]y=6.25[/tex]

Therefore, the maximum height of of Anna's golf ball is 6.25 units.

x = 5

Step-by-step explanation:

26x + 10x = 180°

36x = 180

x = 180/36

x = 5

Answer:

D : 125°,125°,55°,55°

Step-by-step explanation:

Finding the interior angles makes the question easier.

The two base angles for b1 are both 125°, and the two base angles for b2 are both 55°.

Because a straight line is 180°, we can find the exterior angles by subtracting the interior angles from 180°.

180°-55° = 125°

180°-125° = 55°

Answer:

Answer:

216 cm^2

Step-by-step explanation:

Alright, first lets knock out the rectangle. This would be found by doing L * H. For the length it would be 14. For the height, it would be 12.

14 * 12 = 168

Next with the triangle, it has a length, or "base" of 8 and the same height of 12. For a triangle, do (B * H) / 2 as the formula.

(8 * 12) / 2

96 / 2

48

Now, combine these two values to get the total:

168 + 48 = 216 cm^2

All done!

Hi there! In this problem, you should have the knowledge of three basic Trigonometric Ratio.

Now that we know three basic ratio. Let's check each choices!

This choice is wrong because we focus on the 50° angle. When we focus on 50°, sin50° should be d/x and not d/c.

This choice is also wrong because in ratio, it's cos50° that adjacent/hypotenuse.

This choice is correct! As ratio states, tanA = opposite/adjacent.

This choice is wrong. x/c is a reciprocal of cosine which is 1/cos. We call the reciprocal of cosine as secant or sec in short.

This choice is wrong as x/d is a reciprocal of sine which is 1/sin. We call the reciprocal of sine as cosecant or cosec/csc in short.

This choice is right by the ratio. Nothing really much to explain since we follow by ratio that is defined.

Answer

Questions can be asked through comment.

Furthermore, tan also has its reciprocal form itself which is called cotangent also known as cot in short.

Hope this helps, and Happy Learning! :)
