Is this true or false?

Answer:

38

Step-by-step explanation:

2(2) = 4

4(5) = 20

20(6) = 120

120/3 = 40

40 - 3 = 37

37 + 1 = 38

Answer:

∠V = 32°

Step-by-step explanation:

VW = UV

⇒ Isosceles triangle. So, the angles opposite sides are equal.

∠W = ∠U

∴ ∠W = ∠U = 74°

 Sum of all angles of triangle = 180

74 + 74 + ∠V = 180

       148 + ∠V = 180

                ∠V = 180 - 148

∠V = 32°

The probability of pulling a white marble from the jar is 0.

Probability determines the odds that an event would happen. The odds usually lie between 0 and 1.

The probability of pulling a white marble = total number of white marbles / total number of marbles

0 / 40 = 0

Answer:

416 square centimeters

Step-by-step explanation:

Formula for finding area of a trapezoid :

A = 1/2 x (a + b) x h

Solving :

Answer:

416 cm²

Step-by-step explanation:

The figure we are given, is a trapezoid. Let's apply the "area of trapezoid" formula to determine the area of the trapezoid provided.

[tex]\boxed{\text{Area of trapezoid:} \ \dfrac{a_1 + a_2}{2} h}[/tex]

[Where a₁ and a₂ are the measure of the parallel sides and h is the height]

Let's plug the height and the parallel sides into the formula and simplify it:

[tex]\text{Area of trapezoid} = \dfrac{38 + 14}{2} \times 16}[/tex]

[tex]\text{Area of trapezoid} = \dfrac{52}{2} \times 16}[/tex]

[tex]\text{Area of trapezoid} = 26 \times 16}[/tex]

[tex]\boxed{\text{Area of trapezoid} = 416 \ \text{cm}^{2}}[/tex]

Therefore, the area of the trapezoid is 416 cm².

The roots of the equation [tex]x^{2}[/tex]-15x +2 =0 are 14.865 and 0.135

Completing the square method is one of the methods to find the roots of the given quadratic equation.

Given equation is:

[tex]x^{2}[/tex]-15x +2 =0

Using Completing the Square method we have

[tex]x^{2}[/tex]-15x +2 + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] =0

Now,

[tex]x^{2}[/tex]-15x + [tex](\frac{15}{2})^{2}[/tex] - [tex](\frac{15}{2})^{2}[/tex] +2=0

or, [tex][x-(\frac{15}{2})]^{2}[/tex] - 225/4 +2 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] -217*4 =0

or,  [tex][x-(\frac{15}{2})]^{2}[/tex] = 217/4

or,  [tex]x[/tex] = [tex]\pm \frac{14.73}{2} + \frac{15}{2}[/tex]

or, [tex]x_1[/tex]= 14.865, [tex]x_2[/tex]= 0.135

Thus, the roots of the quadratic equation are: 14.865 and 0.135

Answer:

x=21

Step-by-step explanation:

For simplicity's sake, I started by naming the angles. Please reference the attachment.

For this, we're using parallel lines with one intersecting line (transversal) to give us valuable information about the angles.

First, based on the Corresponding Angles Theorem, corresponding angles, such as A and B, are congruent.

This means that angle B can also be represented by the expression 6x-19.

Furthermore, since angles B and C are on the same line, they must be supplementary, meaning that they add up to 180 degrees.

This said, we can set up an equation to solve for x because B+C=180

6x-19+3x+10=180

Combine Variables

9x+10-19=180

9x-9=180

Add 9 to both sides to isolate x

9x=189

Divide both sides by 9

x=21

This problem could have also been solved with various other theorems such as, but not limited to:

Keep in mind a prerequisite for all of these theorems except the vertical angles theorem are that it must be for a transversal cutting/intersecting 2 parallel lines.

The Alternate Exterior Angles Theorem states that alternate exterior angles are congruent (A and D)

The Alternate Interior Angles Theorem states that alternate interior angles are congruent (C and E)

The Vertical Angles Theorem states the vertical angles- angles across from each other- are congruent (B and D)

The Same Side Exterior Angle Theorem states that same side exterior angles supplementary (A and F)

The Same Side Interior Angle Theorem states that same side interior angles are supplementary (E and B)

The total area of the fields that Ram has is  170,900 square meters ( 170900 m²)

From the question, we are to determine the total area of the fields that Ram has

Since the fields are square in shapes, we will use the formula for calculating the area of a square

The area of a square can be calculated by using the formula,

A = s²

Where A is the area

and s is the side

For the first field

s = 350 m

∴ A = 350²

A = 122500 m²

For the second field

s = 220 m

∴ A = 220²

A = 48400 m²

Then,

The total area of the fields = 122500 m² + 48400 m²

The total area of the fields = 170900 m²

Hence, the total area of the fields that Ram has is  170,900 square meters ( 170900 m²)

The area of a 2D form is the amount of space within its perimeter. The surface area of each polyhedron is 82units², 48units², and 48units², respectively.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The surface area of the polyhedrons can be written as,

I Polyhedron

SA = 2[(5×6)+(5×1)+(6×1)] = 2[(30)+(5)+(6)] = 82 units²

II Polyhedron

SA = (4×4)+4(0.5×4×4) = 16+32 = 48 units²

III Polyhedron

SA = (3×3) + 2(0.5×4×3) + (5×3) + (4×3) = 48 units²

Hence, the surface area of each polyhedron is 82units², 48units², and 48units², respectively.

The solution set of the equation is (0, 7)(-1, 6)

y = x² + 2x + 7

y = x + 7

y = x² + 2x + 7

y = x + 7

x² + 2x + 7 = x + 7

x² + 2x - x + 7 - 7 = 0

x² + x = 0

x(x + 1) = 0

Therefore,

x = 0 and x = -1

Substitute the value in equation(ii)

when x = 0

y = x + 7

y = 0 + 7

y = 7

when x = -1

y = -1 +7

y = 6

Therefore, the solution set are (0, 7)(-1, 6)
