I think 84 degrees................ :)
Answer: x=192 degrees
Explanation:
A triangle is always equal to 180, therefore you would add the insides of it. 52 + 44 = 96 Than you would subtract 96 from 180 = 84 so the inside part of the triangle with the missing amount would be 84. Then that part of the triangle is adjacent so 84 would go on the outside part as well. Then you would multiply 84 by 2 and subtract the 168 from 360 and get 192.

D.K.G.S. and B are five points on line / • KG + GD = KD • SD + DB = SB KS + SG = KG What is the order of the points from left to right based on their position along line 1? A B, D, G, K, S B K, G,D,S, B C KG,S,D,B D K,S, G,D, B

Answers

Answer: K,S,G,D,B

because KG + GD = KD => G is between K and D

SD + DB = SB => D is between S and B

KS + SG = KG => S is between K and G

=> The order of the points from left to right is   K,S,G,D,B

A insurance salesperson earns a salary of $4,200 per month plus a commission of 3% of sales. How much must the salesperson have to sell to make an income of at least $4,500?

Answers

Answer:

x = 10,000

Step-by-step explanation:

commision earned = $4500. - $4200

commision = 300

therefore:

commision = 3% of the amount of the sales

300 = 3% of x( the price isn't known)

300 = 3/100 * x

300 = 3x /100

multiplying both sides by 100

300 x 100 = 3x/100 x 100

30000 = 3x

Divide through by 3

x = 10,000.

the amount of the sales = 10,000

______________

To check

commision = 3% of 10,000

commision = 300

Step-by-step explanation:

I took the test and got it right.

Your welcome :)

Using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.

What are perpendicular bisectors?

Lines that cut through the middle of each side of a triangle and are perpendicular to the specified side are known as the perpendicular bisectors of the triangle.

The standard construction of the perpendicular bisector of MN will be,

Step 1: Sketch a line segment with any appropriate length, XY.

Step 2: Using a compass, draw arcs above and below the line segment, with X serving as the center and XY's width greater than 50%.

Step 3: Carry out Step 2 but use Y as the center. Step 4: Write "P" and "Q" next to the junction points.

Thus, using a compass, draw one arc with point M at the center and point N intersecting it as the first step in the typical construction of the perpendicular bisector of MN. Option C is correct.

Five less than twice the value of a number is equal to three times the quantity of four more than one-half the number. What is the number?

Answers

Answer:

2x - 5 = (1/2)

 

4x - 10           [multiply by 2]

 x - 10 = -13                 [subtract 3x from both sides]

  x = -3                        [add 10 to both sides]

Step-by-step explanation:

The required number would be 34 which is determined by the phrase "five less than twice the value of a number is equal to three times the quantity of four more than one-half the number"

What is algebra?

Algebra is the analysis of mathematical representations, while logic is the manipulation of those symbols.

When broken down, these sorts of statements are not intimidating. First, consider "five less than twice the value of a number."

"Twice the value of a number" is simply 2x.

"Five less" is simply -5, so for the first part we have (2x-5)

Examine the second section next. "Three times four times more than one half the number."

"Three times the quantity" simply indicates "three times something."

4 + "one half the number" or 4 + (1/2)x is "the quantity of four more than one half the number."

So the second part is simply 3(4+x/2).

Finally, we complete the equation, (2x-5) = 3(4+x/2) and solve for x.

2x-5 = 12 + (3/2)x

2x-(3/2)x = 17

x/2 = 17

x = 34

Therefore, the required number would be 34.

what is the area of the real object that the scale drawing models???

Answers

Answer:

D. 40 cm^2

Step-by-step explanation:

The scale factor is a ratio of linear dimensions. The real object's linear dimensions are 2 times the size of the corresponding dimensions in the drawing. For example the length of the object is twice the length of the scale drawing.

The ratio of the areas is the square of the ratio of the linear dimensions.

linear scale factor    1:2

ratio of areas   (1:2)^2 = 1:4

The area of the object is 4 times the area of the scale drawing.

A = 4 * 10 cm^2 = 40 cm^2

John had $50 to spend at the mall. He purchased a shirt for $17.50, a pair of pants for $24.99, and a belt for $6.99. John used a coupon that took $5.00 off his purchase. The total sales tax was $3.06. How much money does John have left after his purchases?

Answers

Answer:

John has 2 dollars and 46 cents left after his purchases.

Step-by-step explanation:

50 - 17.50 = 32.50

32.50 - 24.99 = 7.51

7.51 - 6.99 = 0.52

0.52 + 5.00 = 5.52
