Answer:

x = 129º

Step-by-step explanation:

It will take some time to elaborate but start this way:

you see the triangle with the 58º and 57º? Now by rule, the sum of all angles ina triangle is 180º

so 57+58 =  115

to discover the other angle you just have to 180-155 = 65

Now that you know the 65º by rule the angle facing it is exactly the same, follow from there, solve all triangles until you get to x...

Answer:

5.

Step-by-step explanation:

If you know your multiplication, you would know that 8x5=40. so, 40 divided by 8 equals 5. and if you dont have 8x5 memorized, do 5x10. 50. 10-8=2. 5x2=10. 50-10=40. Voila!

Answer: c= 35x + 75

Step-by-step explanation:

If he earns $75 then that will be the constant amount which means it will never change, plus $35 for x cars, will give us the expression 35x + 75 and that has to equal c which is his total earnings.

Answer:

Step-by-step explanation:

Total earnings for x cars sold:

Answer: 6.324555 ?

Step-by-step explanation: The distance formula is the square root of

((-5-(-7))² + (7-1)²)

(-5-(-7))=2, and 2² = 4.

(7-1)=6, and 6²=36.

4+36=40

the square root of 40 is about 6.324555.

Answer:

0.0124

Step-by-step explanation:

The negative sign means that we need to move the decimal sign to the left. Since it's -2, the decimal place will be moved to 2 places to the left. From 1.24, it will become 0.0124

Answer:

Step-by-step explanation:

Cost of 1 T-shirt = $ 10

Sales tax for 1 T-shirt = 5% * 10 = 0.05 * 10

Cost of n T-shirt = $ 10n

Sales tax for 'n' T-shirts = 0.05 * (10n)

Sales tax on  'n'  T-shirts = Sales tax for 1 T-shirt  * (Cost of n T-shirt)

Answer:

the cost of the t shirt  = 10 times the sale tax which is 5%

Answer:

3x+30= 116° 2x=64°

Step-by-step explanation:

the angle below 2x is the same as 3x+20 so we know that 5x+20=180 so solve this

5x+20=180

5x=160

x=32

sub x into the angle equations

3(32)+20=116

2(32)=64

Answer:

x=32°

Step-by-step explanation:

3x+20+2x=180°(being co interior angle)

3x+2x+20=180°

5x=180-20

5x=160

x=32°

Answer:

32.5 miles in 30 minutes.

Step-by-step explanation:

There are a total of 4 - 30 minute segments in a period of two hours. Therefore, in this question, we can simply divide the total distance that Mr Edwards travelled during those two hours by the 4 segments, and that would give us the distance travelled in a single segment of 30-minutes.

130 / 4 = 32.5 miles

Finally, we can see that Mr Edwards travelled 32.5 miles in 30 minutes.

Answer:

1.28

Step-by-step explanation:

slope of line f = (94 - 19)/(-4 - 92) = -75/96

since line g is perpendicular to line f, the product if their slope = -1

therefore, 75/96 x slope of line g = -1

slope if line g = -1/(-75/96) = 96/75 = 1.28

Answer:

178.695

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

recall that all internal angles of a triangle sum up to 180 deg

we are given that ∠F is a right angle = 90 deg

Simply sum all all the angles and equate the sum to 180 deg

90 + (3x+29) + (5x-3) = 180

90 + 3x+29 + 5x-3 = 180

90 + 3x+29 + 5x-3 = 180

116 + 8x = 180  (subtract 116 from both sides)

8x = 180 - 116

8x = 64  (divide both sides by 8)

x = 64/8

x = 8

Answer:

  a) no

  b) yes

  c) maybe (no)

Step-by-step explanation:

There are two versions of the triangle inequality. One requires ...

  a + b > c

for any triple of side measures a, b, c.

The other allows ...

  a + b ≥ c

which admits "triangles" that have zero height and look like line segments.

Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.

a)

  [tex]16+21=37\ngtr39\qquad\text{not a triangle}[/tex]

b)

  [tex]27+34=61>58\qquad\text{could be a triangle}[/tex]

c)

  [tex]9+29=38\ge38\qquad\text{could be a triangle if "equal to" is allowed}[/tex]

Step-by-step explanation:

Answer:

Jimmy purchased 8 of the children's ticket and 7 of the adult's ticket.

Step-by-step explanation:

Let c = children tickets

Let a = adult tickets

Given the following data;

Number of tickets = 15

Total amount spent = $140

Cost of each children ticket = $7

Cost of each adult ticket = $12

*Translating the word problem into an algebraic equation (system)*

For the total number of tickets;

[tex] c + a = 15 [/tex] .........equation 1

For the total amount spent;

[tex] 7c + 12a = 140[/tex] ..........equation 2

*Solving the linear equation by using the substitution method*

Making c the subject in equation 1:

[tex] c = 15 - a[/tex] .......equation 3

Substituting "c" into equation 2;

[tex] 7(15 - a) + 12a = 140 [/tex]

Simplifying the equation, we have;

[tex] 105 - 7a +12a = 140[/tex]

[tex] 105 + 5a = 140[/tex]

Rearranging the equation, we have;

[tex] 5a = 140 - 105[/tex]

[tex] 5a = 35[/tex]

[tex] a = \frac {35}{5} [/tex]

a = 5 (For the $12 adult ticket).

To find the number of children tickets;

Substituting "a" into equation 3;

[tex] c = 15 - 7[/tex]

c = 8 (For the $7 children ticket).
