A movie theater offers 30% off the price of a movie ticket to students from your school. The regular price of a movie ticket is $8.50. what is the discounted price that you would pay for a ticket?
Answer:
$5.95
Step-by-step explanation:
To get the discounted price, we need to find how much is taken off from the regular price.
x/8.50=30/100
30×8.50=255
255/100=2.55
$2.55
Next, we need to subtract $2.55 from $8.50 to get the discounted price.
8.50-2.55=5.95
$5.95
$5.95 is the discounted price.
I hope this helped! :)
Answer: 5.95 dollars
Step-by-step explanation:
You are skiing down a mountain with a vertical height of 1200 feet. The distance that you ski as you go from the top down to the base of the mountain is 2900 feet. Find the angle of elevation from the base to the top of the mountain.
Answer:
24.44°
Step-by-step explanation:
The set up will give a right angled triangle.
Given
The length of the hill (hypotenuse) = 2900feet
Vertical height (opposite) = 1200feet(That side is opposite the angle of elevation)
According to SOH;
sin theta = opp/hyp
Sin theta = 1200/2900
Sin theta = 12/29
Sin theta= 0.4138
theta= arcsin(0.4138)
theta = 24.44°
Hence the angle of elevation from the base to the top of the mountain is 24.44°

(Sin 5A - Sin 7A - Sin 4A + Sin 8A)÷
(Cos 4A - Cos 5A - Cos 8A + Cos 7A)=
Cot 6A
We use a similar strategy as in your previous question. Rewrite:
sin(5x) = sin(6x - x) = sin(6x) cos(x) - cos(6x) sin(x)
sin(7x) = sin(6x + x) = sin(6x) cos(x) + cos(6x) sin(x)
→ sin(5x) - sin(7x) = -2 cos(6x) sin(x)
sin(4x) = sin(6x - 2x) = sin(6x) cos(2x) - cos(6x) sin(2x)
sin(8x) = sin(6x + 2x) = sin(6x) cos(2x) + cos(6x) sin(2x)
→ sin(8x) - sin(4x) = 2 cos(6x) sin(2x)
cos(5x) = cos(6x - x) = cos(6x) cos(x) + sin(6x) sin(x)
cos(7x) = cos(6x + x) = cos(6x) cos(x) - sin(6x) sin(x)
→ cos(7x) - cos(5x) = -2 sin(6x) sin(x)
cos(4x) = cos(6x - 2x) = cos(6x) cos(2x) + sin(6x) sin(2x)
cos(8x) = cos(6x + 2x) = cos(6x) cos(2x) - sin(6x) sin(2x)
→ cos(4x) - cos(8x) = 2 sin(6x) sin(2x)
Then
(sin(5x) - sin(7x) - sin(4x) + sin(8x)) / (cos(4x) - cos(5x) - cos(8x) + cos(7x))
= (2 cos(6x) sin(2x) - 2 cos(6x) sin(x)) / (2 sin(6x) sin(2x) - 2 sin(6x) sin(x))
= (2 cos(6x) (sin(2x) - sin(x))) / (2 sin(6x) (sin(2x) - sin(x)))
= cos(6x) / sin(6x)
= cot(6x)
QED
A cube has a side length of 8 inches. Select all values that represent the cubes volume in cubic inches. A. 8^2 B. 8^3 C. 6 x 8^2 D. 6 x 8 E. 8 x 8 x 8
Answer: B. 8^3; E. 8 x 8 x 8
Step-by-step explanation:
From the question, we are informed that a cube has a side length of 8 inches.
To calculate the volume of a cube, we multiply the length given thrice. In this case, the length of the cube is 8 inches. Therefore, its volume will be:
= 8^3
= 8 × 8 × 8
= 512 inches cubed
Therefore, the correct options are:
B. 8^3
E. 8 x 8 x 8

What is the image of (6,5) under a counterclockwise
rotation of 180°?
Answer:
(-6, -5)
Step-by-step explanation:
For a rotation of 180 degrees no matter the direction, you just flip the sign. In (6, 5) both are positive so you just change them to a negative.

Explain how to use the distributive property to find the product (3) 4 1/5
Answer:
[tex]\frac{63}{5}[/tex]
Step-by-step explanation:
Given expression:
(3) 4[tex]\frac{1}{5}[/tex]
The distributive law is mostly applied to multiplication and division which helps to expand a parentheses;
4[tex]\frac{1}{5}[/tex] can be written as [tex]\frac{21}{5}[/tex]
Now;
(3) [tex]\frac{21}{5}[/tex]
With distributive property, we simply multiply the two terms;
3 x [tex]\frac{21}{5}[/tex] = [tex]\frac{63}{5}[/tex]
Answer:
Rewrite 3 ( 4 1 /5 ) as 3 ( 4 + 1 5 ) . Distribute the 3 to get 3(4) + 3 ( 1 /5 ) . Multiply to get 12 + 3 /5 . Then add to get 12 3 /5
Step-by-step explanation:
Four brothers received the same amount of money to go to the movies. Each boy spent $16. Afterward, the boys had $48 altogether. Write an equation that represents the amount of money m each brother received.
Answer:
Equation is: 4(x - 16) = 48
Amount each received = $28
Step-by-step explanation:
We are told that the foot brothers received the same amount of money to go to the movies.
Let's say they each receive "x" in amount.
Which means total amount is;
x + x + x + x
Now,we are told that each boy spent $16.
Thus,amount left after spending is;
(x - 16) + (x - 16) + (x - 16) + (x - 16) = 4(x - 16)
We are told this amount after spending was $48 altogether. Therefore;
4(x - 16) = 48
Divide both sides by 4 to get;
x - 16 = 48/4
x = 16 + 12
x = $28

Step-by-step explanation:
Exponential Decay Function
The exponential function is frequently used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function can be expressed as follows:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The company puts out an advertisement for a job opening. Initially, the company got 90 responses to the advertisement. Each day, the responses declined by 10%.
This is an example where the decay model can be used to calculate the responses to the advertisement at the day t.
The initial value is Co=90, the decaying rate is r=10% = 0.10. The model is written as:
[tex]C(t)=90\cdot(1-0.1)^t[/tex]
Calculating:
[tex]C(t)=90\cdot(0.9)^t[/tex]
We are required to calculate the number of responses at day t=19, thus:
[tex]C(19)=90\cdot(0.9)^{19}[/tex]
C(19)=12 responses

Answer:

Step-by-step explanation:
Given
[tex]Perimeter = 17x - 5[/tex]
[tex]Side\ 1 = 3x + 5[/tex]
[tex]Side\ 2 = 8x - 3[/tex]
Required
Determine the length of the third side
The perimeter of a triangle is calculated as thus:
[tex]Perimeter = Side\ 1 + Side\ 2 + Side\ 3[/tex]
Substitute values for Perimeter, Side 1 and Side 2
[tex]17x - 5 = 3x + 5 + 8x - 3 + Side\ 3[/tex]
Collect Like Terms
[tex]17x - 5 = 3x + 8x + 5 - 3 + Side\ 3[/tex]
[tex]17x - 5 = 11x + 2 + Side\ 3[/tex]
Solve for Side 3
[tex]Side\ 3 = 17x - 11x - 5 - 2[/tex]
[tex]Side\ 3 = 6x - 7[/tex]
Hence, the length of the third side is 6x - 7 units

what is 250 to 400 in percentage
Answer:
60%
Step-by-step explanation:
:))))))
step 1 Address the formula, input parameters & values
Formula :
Increase
Initial Value
x 100 = Percent Increase (%)
Initial Value X = 250 & New Value Y = 400
Increase = (Y - X)
(400 - 250)
250
x 100 = ?
step 2 Apply the values in the percentage increase {(Y - X)/X x 100} formula
=(400 - 250)
250
x 100
=150
250
x 100
= 60%
(400 - 250)
250 x 100 = 60%
60 percent increase (%↑) or raise from 250 is 400 or 160% of 250 is 400
Answer:
62.5%
Step-by-step explanation:
Divide 250 by 400 to get 0.625. Then, multiply by 100 to get the percentage, 62.5%.
