Answer:

x = 71°

Step-by-step explanation:

By applying triangle sum theorem in ΔBHD,

m∠DBH + m∠BHD + m∠HDB = 180°

40° + m∠BHD + 31° = 180°

m∠BHD = 180° - 71° = 109°

m∠BHD + m∠DHE = 180° [Linear pair of angles]

109° + x° = 180°

x = 180° - 109°

x = 71°

Answer:

71

Answer:

As a fraction 2.75 is 2 3/4 (11/4)

Hope this helped :)

Answer:

2 3/4 or 11/4

Step-by-step explanation:

2 = 2

0.75 = 3/4

Therefore 2.75 = 2 3/4

If you want an improper fraction then you'd get 11/4

Answer:

we conclude that only two points (-5, 5) and (-1, 4) satisfy the system of inequalities.

Step-by-step explanation:

Given the system of inequalities

y > 2x+3

y+3x ≤ 1

Checking the point (0, 5)

Let us substittue the point (0, 5) to check if it is satisfies system of inequalities

y > 2x+3

5 > 2(0) + 3

5 > 3

True

now check for the second inequality

y+3x ≤ 1

5 + 3(0) ≤ 1

5 ≤ 1

False

Therefore, the point (0, 5) does not satisfy the system of inequalities

Checking the point (-5, 5)

Let us substittue the point (-5, 5) to check if it is satisfies system of inequalities

y > 2x+3

5 > 2(-5) + 3

5 > -10+3

5 > -7

True

now check for the second inequality

y+3x ≤ 1

5 + 3(-5) ≤ 1

5-15 ≤ 1

-10 ≤ 1

True

Therefore, the point (-5, 5) satisfies the system of inequalities.

Checking the point (-1, 4)

Let us substittue the point (-1, 4) to check if it is satisfies system of inequalities

y > 2x+3

4 > 2(-1) + 3

4 > -2+3

4 > 1

True

now check for the second inequality

y+3x ≤ 1

4 + 3(-1) ≤ 1

4-3 ≤ 1

1 ≤ 1

True

Therefore, the point (-1, 4) satisfies the system of inequalities.

Checking the point (0, -5)

Let us substitute the point (0, -5) to check if it satisfies the system of inequalities

y > 2x+3

-5 > 2(0) + 3

-5 > 0+3

-5 > 3

False

now check for the second inequality

y+3x ≤ 1

-5 + 3(0) ≤ 1

-5+0 ≤ 1

-5 ≤ 1

True

Therefore, the point (0, -5) does not satisfy the system of inequalities.

Checking the point (-3, -3)

Let us substitute the point (-3, -3) to check if it satisfies the system of inequalities

y > 2x+3

-3 > 2(-3) + 3

-3 > -6+3

-3 > -3

False

now check for the second inequality

y+3x ≤ 1

-3 + 3(-3) ≤ 1

-3 - 9 ≤ 1

-12 ≤ 1

True

Therefore, the point (-3, -3) does not satisfy the system of inequalities.

Hence, we conclude that only two points (-5, 5) and (-1, 4) satisfy the system of inequalities.

Pair (1.00, 0.50)

Answer:

Step-by-step explanation:

use Pythagorean theorem:

a² + b² = c²

where a = 2

           b = x/2  

           c = √13

plugin values into the formula:

2² + (x/2)² = (√13)²

4² + x² = 13

       4

16 + x² = 13 (4)

x² = 52 - 16

x = √36

x = 6

Step-by-step explanation:

the answer is:

1. 12.5

2.26.67

Answer:

6) Two angles are called supplementary when their measures add up to 180 degrees. For example, two right angles are supplementary angles.

7) When the sum of two angles is equal to 90 degrees, they are called complementary angles. For example, 30 degrees and 60 degrees are complementary angles.

8) you have to plot the points on the graph and draw a line and label it with L at one point and M at another point.

9) x = 20

m < A = 65

m < B = 25

Step-by-step explanation:

9)

3x + 5 + 2x - 15 = 90

3x + 2x + 5 - 15 = 90

5x - 10 = 90

5x - 10 + 10 = 90 + 10

5x = 100

5 / 5x = 100 / 5

x = 20

A = 3x + 5

A = 3(20) + 5

A = 60 + 5

A = 65

B = 2x - 15

B = 2(20) - 15

B = 40 - 15

B = 25

Answer:

The correct option is (b).

Step-by-step explanation:

Given that,

Miranda is calculating her expected expenses for her week long trip to Turkey.

Flight cost = 928 TL

Lodging costs = 755 TL

She spend 814 TL for food.

We need to find Miranda's total. It is equal to the sum of all above data such that,

Total = 928+755+814

= 2497 TL

Hence, Miranda's total is 2497 TL.

Answer:

[tex]Probability = \frac{1}{6}[/tex]

Step-by-step explanation:

Given

The above table

Required

Determine the probability of a sum that is a multiple of 6

Represent the event that an outcome is a multiple of 6 with M.

List out all possible values of M

[tex]M = \{6,6,6,6,6,12\}[/tex]

Number of M is

[tex]n(M) = 6[/tex]

Total possible outcome is:

[tex]n(Total) = 36[/tex]

The theoretical probability is then calculated as follows:

[tex]Probability = \frac{Number\ of\ desired\ outcomes}{Number\ of\ possible\ outcomes}[/tex]

In this case, it is:

[tex]Probability = \frac{n(M)}{n(Total)}[/tex]

[tex]Probability = \frac{6}{36}[/tex]

Simplify fraction

[tex]Probability = \frac{1}{6}[/tex]

Answer:

7 sq rt 2

Step-by-step explanation:

must use pythagorean theorem: square of each leg = square of hypotenuse

7 squared the 7 squared = u squared

49+49=u squared

u = square root of 98, which is sq root of 49 times sq root of 2
