Answer:

  C)  14 cm

Step-by-step explanation:

A triangle solver can quickly show you the third side is 14 cm.

__

The law of cosines can be used for this purpose. If the given sides are 'a' and 'b', and the third side is 'c', then that law tells you ...

  c² = a² +b² -2ab·cos(C)

  c² = 7² +11² -2·7·11·cos(100°) ≈ 196.74

  c ≈ √196.74 ≈ 14.03

The length of the third side is about 14 cm.

Answer:

Step-by-step explanation:

Ok, so we have the equations:

7x-2y=-13

and

2y-5x=11

So first things first, we can cancel out 2y from both equations because they are common factors.

So we are left with the equations:

7x=-13

and

5x=11

So we add the two common factors and get:

12x=-24

And now we divide on both sides and get:

x=-2

Answer:

y=4

Step-by-step explanation:

l is a horizontal line

Horizontal lines are of the form

y =

Since the y coordinate is 4

y=4

Twelve and six hundred seven thousandths

Answer:

1. 3x + 2y = -4

2. y = 1/2x + 3

3. y = 3/14x - 3/7

Answer:

10 and -10

Step-by-step explanation:

Absolute value is the distance of a number from 0. Absolute value must be positive because you can not a have a negative distance from 0. The two numbers that have a distance of 10 from 0 on the number line are 10 and -10.

Answer:

The symbol for absolute value is two vertical lines. Since opposites are the same distance from the origin, they have the same absolute value. For example, the absolute value of "negative 10" is ten, and the absolute value of "positive 10" is also 10.

Step-by-step explanation:

Answer:

horizontal line because it doesn't pass vertical line test

Answer:

$40 + 10x

Step-by-step explanation:

Given that:

Original cost of data plan = $40 per month for 10 GB of data

Additional data cost = $10 per GB when usage is above the original data cap

Hence, amount to be paid when usage is over the original data cap by x GB :

Original amount + (additional cost per GB * additional GB used)

$40 + ($10 * x)

$40 + 10x

Answer:

Equation is the second one, term is the first one, expression is the third one, inequality is the last one

Step-by-step explanation:

Answer: equation is the one with the =, expression is 4x+(-2), inequality is the one with the greater than sign, and the term is -9

Answer:

25x = 75 (Because they are alternate interior angles)

=> x = 75/25

=> x = 3

So, x = 3

Because 25x is equal to 75, the two lines (u and v) are parallel

x = 3

180-75 = 105

180-105 = 75

75/25 = 3

Answer:

See below for answers

Step-by-step explanation:

1st Problem:

Because the figure is a triangle, it's interior angles will add up to 180 always. Since it's a right triangle, we know one of the angles is 90, but we'll need to set up an equation to solve for x.

90+(2x-2)+(x+5)=180

2x-2+x+5=90

3x+3=90

3x=87

x=29

Therefore, B) 29, is the correct answer

2nd Problem:

Given side lengths of a, b, and c, if a+b<c, then it's a triangle. Since 8+8 is not less than 16, the sides do not make a triangle. The hypotenuse, c, must always be the longest length.

Therefore, A) Not a triangle, is the correct answer

3rd Problem:

To find angle x, we need the last interior angle of the triangle. Since the interior angles of a triangle add up to 180, we once again set up an equation to find the missing interior angle:

21+34+y=180

55+y=180

y=125

Since the missing interior angle is 125 degrees, it is supplementary to angle x, where supplementary angles add up to 180 degrees as well. So we would subtract 125 from 180 to get x. 180-125=55, so angle x is 55 degrees. Therefore, C) 55, is the correct answer.

4th Problem:

Again, use the Interior Angle Theorem to get x:

58+47+x=180

105+x=180

x=75

Therefore, A) 75, is the correct answer

5th Problem:

3,4,5 is a Pythagorean Triple, so it is a right triangle as 3^2+4^2=5^2. It is also scalene because none of the sides are equal to each other.

Therefore, B) Yes, scalene, is the correct answer

(9, 10)

[tex]\frac{10 - 2}{9 - 3}[/tex]

8/6 = 4/3

Answer:

Angle A is congruent to Angle D

Angle B is congruent to Angle E

Angle C is congruent to Angle F

How?

We can figure this out by looking at the amount of semi-circle things on each angle. Since A and D both have 3 of them, we know they are congruent. We can use this logic to solve the rest of the congruent angles.

Hope This Helps!!! :)

Let me know in the comments if this answer was perfect or if I should change anything!!!

Answer:

A is congruent to D

B is congruent to E

C is congruent to F

Step-by-step explanation:

One way I personally like to do it is looking at the way that it is this may not always work, but in this case, it does. When you look at the way it is written, You see that A is the first letter of the first phrase and D is also the letter of that triangle. You kind of just match them up. If you don't want to do it that way, just look at the vertices and match them up.

Answer:

the fourth month

Step-by-step explanation:

200 + 50m = 100 + 75m

subtract 100 on both sides

100 + 50m = 75m

subtract 50m on both sides

100 = 25m

divide by 25 on both sides

m = 4

Answer:

40.64 cm x 40.64 cm

Step-by-step explanation:

The directions say that 1 centimeter = 16 inches.

1 inch = 2.54 centimeters

Multiply by 16.

16 inches = 40.64 centimeters

We know each length of the square is 1 cm or 16 inches, according to the above.

(btw problem says rectangle, a square can be a rectangle.)

Answer:

[tex] {64m}^{9} {n}^{3} [/tex]

Step-by-step explanation:

Forst thing to do in this is to write it out, it makes more sense of the problem.

[tex]( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } ) \times ( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } ) \times( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2}n } )[/tex]

Now we can solve for the equation, it takes time.

[tex] (\frac{ {16m}^{10} {n}^{4}}{ {m}^{4} {n}^{2} } ) \times ( \frac{ {4m}^{5} {n}^{2} }{ {m}^{2} n} ) \\ \frac{ {64m}^{15} {n}^{6} }{ {m}^{6} {n}^{3} } \\ {64m}^{9} {n}^{3} [/tex]

Answer:

Angle 2 = 45 degrees

Step-by-step explanation:

Angle 1 = Angle D because they are alternate interior angles.

Angle 3 = Angle A because they are alternate exterior angles.

Angle 1 = 135 degrees

Therefore, Angle D = 135 degrees

180 - Angle D = Angle 2

Angle 2 = 180 - 135

Angle 2 = 45 degrees
