In vwx, vw = vx. if mv = 50°, what are measures of w and x?

I'm visualizing that VWX is a triangle.

Since VW = VX ; Two sides are equal, then it is an isosceles triangle.

An isosceles triangle is a triangle that has 2 equal sides and 2 equal angles.

Given: m∠V = 50° ;

Since interior angles must total 180° the remaining 2 unknown angles must have a sum of 130°.

180° - 50° = 130°
130° / 2 = 65°

m∠W = 65° and m∠X = 65°

I have some cheese. I used

hram777 [196]

<h3>Answer: 2500 grams</h3>

============================================

Work Shown:

A = amount of grams of cheese you had originally

B = (2/5)*A = amount of cheese you use up after day 1

C = (3/5)*A = amount of cheese you have left over after day 1

note how B and C add back up to 'A'.

This is because 2/5+3/5 = 5/5 = 1, so,

B+C = (2/5)A+(3/5)A = (2/5+3/5)A = 1*A = A

--------------

D = (2/5)*C = amount of cheese you use up after day 2

E = (3/5)*C = amount of cheese left over after day 2

the variables D and E add up to C

we are told that there are 900 grams of cheese left after day 2, so E = 900

--------------

E = (3/5)*C

(3/5)*C = E

(3/5)*C = 900 ... Plug in E = 900

3C = 900*5 .... multiply both sides by 5

3C = 4500

C = 4500/3 .... divide both sides by 3

C = 1500

This means you had 1500 grams of cheese after day 1

-------------

C = (3/5)*A

(3/5)*A = C

(3/5)*A = 1500 ... plug in C = 1500

3A = 1500*5 ... multiply both sides by 5

3A = 7500

A = 7500/3 .... divide both sides by 3

A = 2500

-----------

<h3>You started off with 2500 grams of cheese.</h3>

After day 1, you use up (2/5)*2500 = 1000 grams of cheese and have 2500-1000 = 1500 grams left over.

After day 2, you use up (2/5)*1500 = 600 grams of cheese and have 1500-600 = 900 grams left over.

The answer is confirmed.

Your class rank in 2018 was 89 out of 360 students. In 2019 your class rank was 95 out of 450 students. a. In which year did you

A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

Given that your class rank in 2018 was 89 out of 360 students, while in 2019 your class rank was 95 out of 450 students, to determine A) in which year did you have the higher percentile ranking, and B) if you had the data on the cumulative GPA of each student at the end of the spring semester in 2018, which measure of average would be the most meaningful - mean, median or mode -, the following calculation should be performed:

360 = 100
89 = X
89 x 100/360 = X
24.72 = X
450 = 100
95 = X
95 x 100/450 = X
21.11 = X

Therefore, A) given that in 2019 you were among the 21.11% of the best students in the class, in that year you had the higher percentile ranking, and B) the measure of average that would be the most meaningful is the median.

Which represents a total cost of 3 dance tickets at a price of c for each, less a one-time $2 discount?

VLD [36.1K]

Answer: c. 3(c - 2)

Step-by-step explanation:
c. 3(c - 2) because, in order to get the total cost, you have to multiply the number of tickets (3) by the price of each ticket (c). Then, you have to subtract the discount (2) from that total cost.
