A shirt was originally priced at $50. The store is having a 35% off sale.
How much will you pay for the shirt after the discount (not including tax
Answer:
$50 with 35% off is $32.50
Step-by-step explanation:
This is the model to find a discounted price:
n with x% off
100 - x = y
n * 0.y = p
With this example, we would find the discounted price like shown below:
$50 with 35% off
100 - 35 = 65
$50 * 0.65 = $32.50
Hope this helps :)

1. In the figure given, calculate the area that is shaded.
Answer:
8.71
Step-by-step explanation:
the area that is shaded is a big shape then two smaller shapes taken out of it
that means you can find the area of the big shape ignoring that there are holes then subtract the area of the holes
big shape side length is 5*2
=10
small shape 1:
0.3*0.3
=0.09
small shape 2:
0.6*2
=1.2
10-(0.09+ 1.2)
10-(1.29)
=8.71

Answer:

Step-by-step explanation:
A new airport is in its planning phase. One particular challenge is that there are several tall buildings in the vicinity. In particular, there's a 450-foot-tall building that is 2500 feet (ground distance) directly East from the end of the runway. The steepest angle the airplane can climb upon takeoff is 15°. Given this scenario, could an airplane take off and clear this tall building?
Answer:
Could an airplane take off and clear this tall building? YES
Step-by-step explanation:
Trigonometry
The building and the ground form a right (90°) angle. The path of the airplane (assumed a straight line) completes the right triangle.
The takeoff angle of the plane θ=15° has the height of the building (450 feet) as the opposite side and the horizontal distance from the end of the runway (2500 feet) as the adjacent side.
The tangent of θ is defined as the following ratio:
[tex]\displaystyle \tan\theta=\frac{\text{opposite leg}}{\text{adjacent leg}}[/tex]
[tex]\displaystyle \tan \theta=\frac{450}{2500}[/tex]
[tex]\displaystyle \tan \theta=0.18[/tex]
Calculating the inverse tangent function:
[tex]\theta=\arctan 0.18[/tex]
[tex]\theta\approx 10^\circ[/tex]
This means the angle needed to clear the tall building is about 10° and it's within the maximum airplane's takeoff angle.
Could an airplane take off and clear this tall building? YES

Rewrite the equation by completing the square:
2x²-3x-5=0
Answer:
(x-¾)² = 49/16
Step-by-step explanation:
0 = 2x² - 3x - 5
2x² - 3x = 5
Divide by the leading coefficient
x²-(3/2)x = 5/2
Complete the square
coefficient of the x term: 3/2
divide coefficient in half: ¾
square it: (¾)²
add (¾)² to both sides to complete the square and keep the equation balanced:
x²-(3/2)x + (¾)² = 5/2 + (¾)²
(x-¾)² = 49/16
If you need to solve for x:
x-¾ = ±√(49/16) = ±7/4
x = 5/2, -1
Answer: (x-5) (x+2) =0

NEED HELP 50 POINTS TO WHOEVER CAN ANSWER
Eric is driving to Los Angeles. Suppose that the distance to his destination (in miles) is a linear function of his total driving time (in minutes). Eric has 65 miles to his destination after 35 minutes of driving, and he has 44 miles to his destination after 63 minutes of driving. How many miles will he have to his destination after 79 minutes of driving?
Answer:
32 Miles
Step-by-step explanation:
Okay so this will take a moment:
Let's set up the following variables:
d = total distance of the trip
v = some rate of velocity/travel
Note: t is not a variable here as it would denote time, but we know the time, so rate of travel as a variable is next best.
With those variables, we can set up 3 equations as follows:
d - 35v = 65
d - 63v = 44
d - 79v = x
The equations being read as:
[total distance] - [time and rate of travel] = [distance remaining]
Now if we restructure each of those equations, you will have:
d = 35v + 65
d = 63v + 44
d = 79v + x
Now you can treat this like a system of equations. First we will solve for the variable: v
Since the total distance remains the same, we can set up the following equation:
35v + 65 = 63v + 44subtract 35v from both sides
65 = 28v + 44subtract 44 from both sides
21 = 28vNow if we turn it around:
28v = 21The common factor of both of these numbers is 7, so divide both by 7:
4v = 3Therefore:
v = [tex]\frac{3}{4}[/tex]That was a lot. NOW that you know the value of v, you can find the total distance that Eric needs to travel, so plug it into one of the equations:
d = 35( [tex]\frac{3}{4}[/tex] ) + 65
Solve, and you get:
d = 91.25 miles = [tex]\frac{365}{4}[/tex] miles
Now that you know what the variables: v and d , you can solve for x in the other equation: d = 79v + x
[tex]\frac{365}{4}[/tex] = 79 ( [tex]\frac{3}{4}[/tex] ) + x
Multiply.
[tex]\frac{365}{4}[/tex] = [tex]\frac{237}{4}[/tex] + x
Subtract.
[tex]\frac{365}{4}[/tex] - [tex]\frac{237}{4}[/tex] = x
Simplify.
x = [tex]\frac{128}{4}[/tex] = 32
Voila! 32 Miles to go! Good Luck!
Find the number that when added to 2.2 produces the same result as the difference between 34.5 and 12.3.
Answer:
Let the required number be 'x'.
Then,
x + 2.2 = 34.5 - 12.3
or, x = 34.5 - 12.3 - 2.2
or, x = 20
So, the required number is 20.

The solution of the given trigonometric equation
[tex]x = \frac{\pi }{6}[/tex]
Step-by-step explanation:
Step(i):-
Given
[tex]cos( 3x - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}[/tex]
[tex]cos( 3x - \frac{\pi }{3} ) = cos (\frac{\pi }{6} )[/tex]
[tex]3x - \frac{\pi }{3} = \frac{\pi }{6}[/tex]
[tex]3x - \frac{\pi }{3 } + \frac{\pi }{3} = \frac{\pi }{6} + \frac{\pi }{3}[/tex]
[tex]3x = \frac{2\pi +\pi }{6} = \frac{3\pi }{6} = \frac{\pi }{2}[/tex]
[tex]x = \frac{\pi }{6}[/tex]
Step(ii):-
The solution of the given trigonometric equation
[tex]x = \frac{\pi }{6}[/tex]
verification :-
[tex]cos( 3x - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}[/tex]
put [tex]x = \frac{\pi }{6}[/tex]
[tex]cos( 3(\frac{\pi }{6}) - \frac{\pi }{3} ) = \frac{\sqrt{3} }{2}[/tex]
[tex]cos (\frac{\pi }{6} ) = \frac{\sqrt{3} }{2} \\\\\frac{\sqrt{3} }{2} = \frac{\sqrt{3} }{2}[/tex]
Both are equal

Find the total surface area of the figure below.
Answer:
240
Step-by-step explanation:
You have to find the area of each indivigual side and then add all the areas together. So like 9x5 is 45 so you take 45 and multiply it by 4 since there are 4 sides identical to that side and then you get 180. Then you multiply 6x5 and that gives you 30 which you then multiply by 60, so then all you gotta do is 60+180=240.
Suppose that one card is to be selected from a deck of 20 cards that contains 10 red cards numbered from 1 to 10 and 10 blue cards numbered from 1 to 10. Let A be the event that a card with an even number is selected, let B be the event that a blue card is selected, and let C be the event that a card with a number less than 5 is selected.
