Answer:

B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.

Step-by-step explanation:

I took the test.

The correct option is B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.

Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.

We are given that Deepak is measuring sides and angles of triangle FGH to determine whether it is congruent to triangle MNP,

In Triangle M N P.

Side P N = 26.7 centimeters,

M N is 18.3 centimeters,

P M is 14.2 centimeters.

Angle P is 40 degrees, angle N is 30 degrees, and angle M is 110 degrees.

He found that Angle G has a measure of 50° and Segment F H is 18.3 centimeters long.

Based on the definition, two triangles are congruent if the three sides are equal and the three angles are equal.

Hence, he need to know the other lengths of the sides of the triangle and the others angles to know if they are congruent or not.

Answer:

The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085

Step-by-step explanation:

The given parameters are;

The coordinates of parallelogram RSTU are;

R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)

The lengths of the sides are (using an online length calculator);

RS = 4.1231

RT = 10

ST = 9.2195

SU = 10.198

TU = 4.1231

UR = 9.2195

Therefore, by definition of a parallelogram, we have;

RS║TU and ST║UR

The slope of RS = (1 - (-3))/(-5 - (-4)) = -4

The slope of ST = (3 - 1)/(4 - (-5)) = 2/9

The equation of the line perpendicular to ST is therefore;

y - 1 = -9/2×(x - (-5))

y = -9x/2 - 43/2

The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1

y = x/4 - 2

The point where the two lines meet is therefore;

-9x/2 - 43/2  =  x/4 - 2

x = -78/19

y = -115/38

The length of the side of the rectangle = 4.1245

The excess width of the rectangle = 0.1085

The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085.

Answer:

Options (B), (C) and (E) are the correct options.

Step-by-step explanation:

Equation that represents relation between the number of cars c and the number of vans v to transport 80 students is,

4c + 6v = 80

Option A.

If c = 12,

4(12) + 6(v) = 80

48 + 6v = 80

6v = 32

[tex]v=\frac{16}{3}[/tex]

Which is not equal to 2.

Therefore, Option A is incorrect.

Option B

If c = 14,

4(14) + 6(v) = 80

56 + 6v = 80

6v = 24

v = 4

Therefore, c = 14 and v = 4 is a pair of solutions.

Option B is correct.

Option C.

If c = 6 and v = 11

4(6) + 6(11) = 24 + 66

                 = 90

This means with 6 cars and 11 vans 90 students can be transported. Therefore, there will be extra space.

Option C is correct.

Option D.

If c = 10 and v = 8

4(10) + 6(8) = 40 + 48

                  = 88

Therefore, 10 cars and 8 vans are enough to transport 80 students.

So option D is incorrect.

Option E.

If c = 20,

4(20) + 6(v) = 80

80 + 6v = 80

v = 0

Therefore, for 20 cars go no vans are needed.

Option E is correct.

Option F.

Constraints in this situation,

Minimum number of cars to be used = 20

c ≥ 20

Minimum number of vans to be used = [tex]\frac{80}{6}[/tex] ≈ 14

v ≥ 14

Therefore, Option (F) is incorrect.

Answer:

C= -8

Step-by-step explanation:

I used a calculator

Answer:

c=-8

Step-by-step explanation:

[tex]\frac{5}{4}c[/tex] + 12 = 2

1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)

1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the             right do it to the left )

1.25c = -10

1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )

c = -8

Answer:

x = 8

Step-by-step explanation:

Since the angles are vertical then they are congruent, thus

5x - 5 = 2x + 19 ( subtract 2x from both sides )

3x - 5 = 19 ( add 5 to both sides )

3x = 24 ( divide both sides by 3 )

x = 8

Answer:

8

Step-by-step explanation:

5x - 5 = 2x + 19

3x - 5 = 19

3x = 24

Answer:

y = 1/2x

Step-by-step explanation:

The equation of the straight line shown in the graph is y = 2x.

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

From the given graph, the points the straight line is passing through can be found as (2, 1) and (4, 2).

The equation of the line for the given points can be written as follows,

(4 - 2)/(2 - 1) = (y - 2)/(x - 1)

=> y - 2 = 2(x - 1)

=> y = 2x - 2 + 2

=> y = 2x

Hence, the equation of the straight line shown in the graph is y = 2x.
