5)Trevon's school is selling tickets to the annual dance competition. On the first day of ticket sales
the school sold 5 senior citizen tickets and 8 student tickets for a total of $94. The school took in
$164 on the second day by selling 10 senior citizen tickets and 13 student tickets. Find the price
of a senior citizen ticket and the price of a student ticket

Answers

Answer:

$8 for student tickets and $4.40 for senior tickets

Step-by-step explanation:

10 (5x +8y=94)

5 (10x +13y=164)

50x+80y=940

- 50x +65y=820

80y-65y= 940-820

15y= 120/15

y=8

(y is the cost of student tickets)

5x+8y=94

5x+8(9)=94

5x+72=94-72

5x=22/5

x= 4.4

A ramp for wheelchair access to the gym has a slope of 5% (that is, the ramp rises 5 feet vertically for every 100 feet of horizontal distance). The entire ramp is built on level ground, and the entrance to the gym is 2 feet above the ground. What is the horizontal distance, in feet, between the ends of the ramp? a 4 b 10 c 40 d 100 e 400

Answers

Answer:

C 40

Step-by-step explanation:

Using proportions, it is found that the horizontal distance, in feet, between the ends of the ramp is:

c 40

This question is solved by proportions, using a rule of three.The slope of 5% means that when the vertical distance rises by 5 feet, the horizontal distance changes by 100 feet.What is the horizontal distance for a vertical distance of 2 feet?

The rule of three is:

5 feet V - 100 feet H

2 feet V - x feet H

Applying cross multiplication:

[tex]5x = 200[/tex]

[tex]x = \frac{200}{5}[/tex]

[tex]x = 40[/tex]

Hence, 40 feet, option c.

What is the positive solution for (x-4)(x+5) = 0

Answers

Answer:x=4

Step-by-step explanation:

You can split this up into two equations

x-4=0

x+5=0

To solve each:

x-4=0

Add 4 to each side

x=4

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

x+5=0

Subtract 5 from each side

x=-5

So your two solutions are -5 and 4 but you want the positive one so the answer is x=4

Which combination of measurements could form a triangle?
A - 5m, 12m, 18m
B - 12m, 32m, 45m
C - 16m, 55m, 72m
D - 18m, 22m, 36m

Answers

Answers D

You divide all sides by 2, get your slope form and multiply by 7

Answer:

D - 18mm, 22mm, 36mm

Step-by-step explanation:

The only way for a triangle to be made, the 2 smallest side lengths must be greater than the longest side length. So for A through C, the smallest sides diden't add up to the longest side, therefore D is the only correct answer.

Answer:

x = 25

Step-by-step explanation:

From the given picture,

In ΔMLN,

m∠NML + m∠MLN + ∠LNM = 180°

61° + 39° + m∠LNM = 180°

100° + m∠LNM = 180°

m∠LNM = 180° - 100°

m∠LNM = 80°

If JK║MN and JN is a transverse intersecting these parallel lines at N and J,

∠LNM ≅ ∠LJK [Alternate interior angles]

(3x + 5)° = 80°

3x = 80 - 5

3x = 75

x = 25
