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:

19%

Step-by-step explanation:

40/50 = x/100

solve for x

x is equal to 20%

but out of the answer choices it's 19%.

Answer: 19%

Step-by-step explanation:

50, percentage decreased by 60% (percent) of its value = 20

50, percentage decreased by 80% (percent) of its value = 10

50, percentage decreased by 19% (percent) of its value = 40.5

50, percentage decreased by 40% (percent) of its value = 30

Hence, the answer is 19%

Step-by-step explanation:

Have a great day!

Answer:

30 + 25 + (4x + 25) = 180

55 + (4x + 25) = 180

-55                    -55

4x + 25 = 125

-25 -25

4x = 100

Divide by 4 on both sides

X = 25

Now we just replace the x with 25

4 x 25 = 100, 100 + 25 = 125 degrees is the missing angle of y

Answer:I have a question

Step-by-step explanation:

About that question is it a right triangle or no

The triangles with side lengths 9.5 feet , 16 feet and 18.5 feet is an acute triangle

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔABC

Now , the height of the triangle is AB = 16 feet

The base of the triangle is BC = 9.5 feet

The hypotenuse of the triangle is AC = 18.5 feet

And , for a triangle , if a² + b² > c² , it is an acute triangle

Substituting the values in the equation , we get

( 9.5 )² + ( 16 )² > ( 18.5 )²

90.25 + 256 > 342.25

346.25 > 342.25

Hence , the triangle is an acute triangle

Answer:

Answer:

54,800 is the correct answer.

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:

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:

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!

Math

Answer:

96 square meters

Step-by-step explanation:

Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.

We then find the area of one face which is 4 * 4 = 16 square meters.

We must then multiply this by the amount of sides on our cube which is 6.

16 * 6 = 96 square meters.

Step-by-step explanation:

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.
