A movie theater sends out a coupon for 15% off the price of a ticket. Write an equation for the situation, where y is the price of the ticket with the coupon, and x is the original price of the ticket. Use pencil and paper. The equation is y what (Use integers or decimals for any numbers in the expression).
Answers
Answer:
y = 0.85x
Step-by-step explanation:
Given that:
Coupon (c) = 15% off
x = original price of ticket
y = price of ticket with coupon
Price of ticket with coupon = (100 - c)% * original price)
y = (100 - 15)% * x
y = 85% * x
y = 0.85x

A forest ranger spots a fire from a 21-foot tower. The angle of depression from the tower to the fire is 12 degrees . To the nearest foot, how far is the fire from the base of the tower?
Answers
Answer:
Step-by-step explanation:
98.8
Answer:
99
Step-by-step explanation:
The angle of depression looking from the tower is the same as the angle of elevation looking at the top of the tower from the spot of the fire. So, tan (12 degrees) = 21 / distance between the tower and fire. Thus, the distance = 21 / tan(12).
tan (12) = 0.2126
Distance = 21 / 0.2126 = 98.78
The question asks about the distance from the base to the fire (to the nearest foot.) Thus, it is 99 feet.

C. (x, y) -> (6x, 6y)
D. (x, y) -> (-y, x)

Step-by-step explanation:
The algebraic representation of the transformation that would not preserve congruence would be:
A). ( x, y) -> ( x + 6, y + 6)
"Algebraic Representation"A coordinated grid is characterized as the point or the grid comprised due to the intersection produced by two lines of the real number.
In this intersection, one line is defined as horizontal and the other line is vertical.
The representation [tex]( x, y) -> ( x + 6, y + 6)[/tex] fails to conserve the congruence.
Thus, option A is the correct answer.

In the given figure, the value of x and y respectively is:
Answers
Answer:
x = 85
y = 65
Step-by-step explanation:
By interior angle sum property of a triangle.
y° + 25° + 90° = 180°
y° + 115° = 180°
y° = 180° - 115°
y° = 65°
y = 65
By remote interior angle theorem of a triangle:
x° = y° + 20°
x° = 65° + 20° (since y = 65)
x° = 85°
x = 85
Express the following numbers as a product of their prime factors

Please show working
Answers
Answer:
2 x 2 x 2 x 3
Step-by-step explanation:
Find two numbers that multiply together to form 24:
2 x 12 = 24
Find two numbers that multiply together to form 12, a factor of 24. Replace 12 with these numbers:
2 x (2 x 6) = 2 x 12 = 24
Find two numbers that multiply together to form 6, a factor of 12. Replace 6 with these numbers:
2 x (2 x (2 x 3)) = 2 x (2x6) = 2 x 12 = 24
Two and three cannot be factored any further, therefore the prime factors of 24 are 2, 2, 2, and 3.

Given the expression
[tex]\frac{(2^3)(2)^4}{2^{10}} \\[/tex]
Using the following laws of indices;
[tex]\frac{a^m}{a^n} = a^{m-n}\\a^m \times a^n = a^{m+n}[/tex]
The expression becomes;
Step 1: Multiplication rule
[tex]=\frac{(2^3)(2)^4}{2^{10}} \\= \frac{2^{3+4}}{2^{10}}\\= \frac{2^7}{2^{10}}[/tex]
Using the division rule of exponent (Quotient of powers);
[tex]= \frac{2^7}{2^{10}} \\= 2^{7-10}\\= 2^{-3}\\also \ a^{-m} = \frac{1}{a^m}\\ 2^{-3}= \frac{1}{2^3}\\\frac{1}{2^3} = \frac{1}{8}[/tex]
