Answer:

XG segment is an angle bisector of ∠YXZ ⇒ C

Step-by-step explanation:

Let us revise the steps of constructing a bisector of an angle

Place compass pin on the vertex of the angle (point X).
Open the compass to a suitable length that and draw an arc to intersect the two sides of the angle at two points (points E and F)
Place the compass pin on one of these new points on the sides of the angle(point E). Stretch the compass to a sufficient length and draw an arc in the interior of the angel
Without changing the span on the compass, place the pin of the compass on the other intersection point on the side of the angle (point F) and make a similar arc. The two small arcs in the interior of the angle are intersecting. in a point (point P)
Join the vertex of the angle (point X) to this intersection of the two small arcs (point P) XP is the bisector of angle X

By comparing these steps with The steps in the figure, you will find that they are the same steps

∵ XP ray intersect YZ segment at G

∴ G belong to XP ray

∵ XP ray is the bisector of ∠YXZ

∴ XG segment is the bisector of ∠YXZ

Then the statement must be true is:

XG segment is an angle bisector of ∠YXZ

Tickets for a play were $2 for each child and $4 for each adult. At one showing of the play, one adult brought 4 children and th

oksano4ka [1.4K]

Answer: 16

Step-by-step explanation:

Tickets for a play were $2 for a child and $4 for an adult.

Tickets price for a child= $2

Tickets price for an adult= $4

One adult brought 4 children. This will give a price of:

(1×4) + (2×4) = 4+8 = $12

The remaining adults brought 2 children each.

Let the remaining adults be y. Each adult will spend:

4+(2×2) = 4+4 = $8

Since there are y adults, it will give 8×y = 8y.

8y + 12 = 60

8y = 60-12

8y = 48

y = 48/8 = 6

The remaining adults are 6. Since we had one adult earlier, total adults will be 7.

To get the number of children that went to the play will be:

(P × number of children) + (price× number of adults) = $60

= (2 × children) + (4 × 7) = $60

= (2 × children) + $28 = $60

= (2 × children) = $60 - $28

= (2 × children) = $32

Children= 32/2

Children= 16

There are 16 children at the play.

How many phone numbers are possible for one area code if the first four numbers are 202-1 , in that order , and the last three n

Mkey [24]

6 phone numbers are possible for one area code if the first four numbers are 202-1

<u>Solution:</u>

Given that, the first four numbers are 202-1, in that order, and the last three numbers are 1-7-8 in any order

We have to find how many phone numbers are possible for one area code.

The number of way “n” objects can be arranged is given as n!

Then, we have three places which changes, so we can change these 3 places in 3! ways

$n! = n \times (n - 1)!$

Hence 3! is found as follows:

$3! = 3 \times (3-1)!\\\\3! = 3 \times 2!\\\\3! = 3 \times 2 \times 1 = 6$

So, we have 6 phone numbers possible for one area code.

Mark just landed a great job as an engineer where he will make $65,000 a year. The company he will work for guarantees a 2% pay

dalvyx [7]

Answer:

65000(1.02)^n.

Step-by-step explanation:

Salary = 65000(1.02)^n where n is the number of years he has worked for the company.

So after one year he earns $6500* 1.02 and after 2 years $65000 * 1.02^2.
