Answer:Number of regular tickets=785
Number of VIP tickets=25
Step-by-step explanation:
Step 1
Cost of Regular tickets=34.50
Costs VIP tickets =78.50
Total tickets sold =810
Cost of both rockets sold=29,045
Using the the given equation that 34.50r + 78.50 (810-r)= 29,045 to determine the number of regular tickets, we have that
Step 2---Solving
34.50r + 78.50 (810-r)= 29,045
34.50+63,585 - 78.50r=29,045
63585-29045=78.50r-34.50r
34,540=44r
r=34540/44
r=785=Number of regular tickets
Number of regular tickets+Number of VIP tickets =810
Number of VIP tickets=810-785=25

write an equation of the line in a slope intercept form of a line that passes through (5,7) and (4,4)
Answer:
y = 3x - 8
Step-by-step explanation:
passes through (5, 7) and (4, 4)
Find slope:
(7 - 4) / (5 - 4)
= 3/1
= 3
This is your slope.
Now plug in a set of coordinates.
y = 3x + b
7 = 3(5) + b
7 = 15 + b
b = -8
Your equation is: y = 3x - 8
Check your work by plugging in the second coordinate pair.
y = 3x - 8
4 = 3(4) - 8
4 = 12 - 8
4 = 4
Your solution is correct.

Identify the percent of change as an increase or a decrease.
15 ounces to 5 ounces
increase
decrease
Find the percent of change. Round to the nearest tenth of a percent if necessary.
The percent of change is
%.
Answer:
It is a 67% decrease
Step-by-step explanation:
First subtract the new amount from the old one
[tex]15-5=10[/tex]
Then divide the difference by the original amount.
[tex]10/15-0.67[/tex]
Move the decimal point over two spots (multiply by 100) to get your percentage.
0.67=67%

Since the triangle has a right angle, we are going to use pythaogoran theoem, which is [tex]a^{2} +b^{2} =c^{2}[/tex], where a and b are the legs and and c is the hypotunese/ slated side. Let set it up.
[tex]3^{2} +6^{2} =c^{2}[/tex]
9+36=c^2
45=c^2
[tex]\sqrt{45}[/tex]=
Then we are going to find a perfect squarre root(1,4,9,16,25....) to simplify the radical
The perfect square root is 9 because 9 goes into 45 5 times.
[tex]\sqrt{9x5}[/tex]
Then take the sqr root of 9 and we have [tex]3\sqrt{5}[/tex]

Carmen is buying a fitness tracker that costs $129.95. She has a coupon for 20%. After the coupon is used, 7% tax will be charged. What is the final cost of the fitness tracker with tax?
9514 1404 393
Answer:
$111.24
Step-by-step explanation:
The use of a 20% off coupon causes the price to be multiplied by (1 -20%) = 0.80. The addition of 7% tax causes the discounted price to be multiplied by (1 +7%) = 1.07. Multiplying the price by these two factors gives ...
$129.95 × 0.80 × 1.07 = $111.24
The final cost with tax is $111.24.
which postulate proves the two angles are congruent?
Answer:
HL (hypotenuse leg)
Step-by-step explanation:
They share a leg, meaning they must be an equal length, and the hypotenuse is congruent, so the hypotenuse leg theorem says they are congruent.

The edges of a cube are 5 centimeters each and the diagonal of a face is approximately 7 centimeters. What is the approximate area of the cross section passing through the diagonals of opposite faces of this cube? A. 12 square centimeters B. 25 square centimeters C. 35 square centimeters D. 49 square centimeters
Answer:
C. 35 square centimeters
Step-by-step explanation:
What we need for this question:
The edges of a cube are 5 centimeters each.
The face diagonal is about 7 centimeters. (actually 7.0710678118655 cm)
To find the cross sectional area here, multiply 5 cm by 7 cm.
5 cm * 7 cm
35 cm² is your final answer, so C is the answer.
Answer:
It is C. 35 square centimeters

5x+2y=13
2x+6y+26
what is the answer to the question
Step-by-step explanation:
5x+2y=13
2x+6y=26
[tex]5x = 13 - 2y \\ x = \frac{13 - 2y}{5} [/tex]
[tex]2( \frac{13 - 2y}{5} ) + 6y = 26[/tex]
[tex] \frac{26}{5} - \frac{4y}{5} + 6y = 26[/tex]
[tex]6y - \frac{4y}{5} = 26 - \frac{26}{5} \\ [/tex]
[tex]5.2y = 20.8 \\ y = 4 \\ x = \frac{13 - 2 \times 4}{5} = \frac{13 - 8}{5} \\ x = 1[/tex]
Find the value(s) of the variable(s). Write your answer(s) in simplest radical form.
Answer:
Step-by-step explanation:
12). By applying Pythagoras theorem in the given right triangle,
Hypotenuse² = (Leg 1)² + (Leg 2)²
x² = 7² + 7²
x² = 2(7)²
x = [tex]\sqrt{2(7)^{2} }[/tex]
x = [tex]7\sqrt{2}[/tex]
13). By sine rule,
sin(60)° = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{\sqrt{3}}{2}=\frac{9\sqrt{3} }{y}[/tex]
y = [tex]\frac{18\sqrt{3} }{\sqrt{3} }[/tex]
y = 18
By cosine rule,
cos(60)° = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
[tex]\frac{1}{2}=\frac{x}{y}[/tex]
x = [tex]\frac{y}{2}[/tex]
x = [tex]\frac{18}{2}=9[/tex]
14). By applying Pythagoras theorem in the given right triangle,
12² = x² + x²
144 = 2x²
72 = x²
x = √72
x = 6√2
Terri wrote the system of linear inequalities.

Select all of the ordered pairs that are part of the solution set for this system of linear inequalities.
(-1,5)
(2, 4)
(3, 3)
(4.6)
(5,2)
Answer:
Step-by-step explanation:
A,b,d
None of the ordered pairs is a solution to the system of linear inequalities.
The given system of inequalities is:
-3x - 3y > -18
-x<-y
From the inequality -3x - 3y > -18
-3(x + y) > -18
Multiply both sides by -1
3(x + y) < 18
Divide both sides by 3
x + y < 18/3
x + y < 6.......(*)
Also from the inequality -x < -y
Multiply both sides by -1
-1(-x) > -1(-y)
x > y...............(**)
Any ordered pair that is a solution to the system of linear inequalities must fulfil the inequalities in (*) and (**)
Since none of the ordered pairs given fulfill the conditions in (*) and (**), none of the given options is correct
