Orchestra Tonight is selling tickets for its local performance. Orchestra fans can buy tickets to sit in the balcony or on the top floor of the concert hall. Tickets for balcony seats are $83 each. Tickets for seating on the floor are 60% of the price of the balcony tickets. Which inequality represents all possible combinations of f, the number of tickets for floor seats and b, the number of tickets for balcony seats, that a person can buy and spend no more than $560. a 83b+138.33f>560 b 83b+49.8f>560 c 83b+49.8f\le560 d 83b+138.33f\le560
Answer:
c
Step-by-step explanation:
Given that:
Cost of balcony seat = $83
Cost of seating on floor = 60% of balcony seat = 0.6 * $83 = $49.8
Number of tickets for floor seat = f
Number of tickets for balcony seat = b
Total amount to spend should not exceed $560;
[(Cost of balcony ticket * number of balcony tickets) + ( cost of floor tickets * number of floor tickets)] ≤ 560
83b + 49.8f ≤ 560
The closest from the options given is :
83b + 49.8 < 560

What is 7x=5y x 6. Plllllssss heeelllp meh. Im stupid and don't know what this is.
Answer:
x=0
Step-by-step explanation:
"x6" was replaced by "x^6".
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :7x-(5y*x^6)=0
7x - 5x6y = 0
7x - 5x6y = -x • (5x5y - 7)
-x • (5x5y - 7) = 0 Hope this helps and you are not stupid everybody has at least something that they dont understand :)))

Step-by-step explanation:
Since the triangles are congruent then corresponding sides are congruent, then
CA = NE , that is
4x + 3 = 11 ( subtract 3 from both sides )
4x = 8 ( divide both sides by 4 )
x = 2

Step-by-step explanation:
Given that sin θ = 3/4 and θ is in Quadrant II:
Find cos θ.
this is for the Sin
*Remember that sin = opposite / hypotenuse*
a² + b² = c² (where a and b are legs and c is the hypotenuse)
From the picture, you can see:
a = 3
c = 4
Plug these into the equation and solve for b.
* a² + b² = c² *
step 1: 3² + b² = 4²
step 2: 9 + b² = 16
step 3: b² = 16 - 9
step 4: b² = 7
step 5: √(b²) = √7
step 6: b = ± √7
FOR COS:
From the picture, you can see that if θ is in quadrant II, b has to be negative.
b = -√7 = adjacent
Remember that cos θ = adjacent / hypotenuse.
cos θ = adjacent / hypotenuse
cos θ = (-√7 / 4)

Bob is hiking down a 15-mile country trail. He could hike at 5 mph for the first 2 hours and then go the rest of the way at 3 mph or he could just go the whole way at 4 mph. How long would each of these options take?
Answer:
1) 11/3 hours or about 3.67 hours.
2) 3.75 hours.
Step-by-step explanation:
Let’s determine the time it will take for Bob to hike for each of the options.
Option 1) Hiking 5mph for 2 hours, then 3mph.
The total distance is 15 miles.
If Bob hiked 5mph for 2 hours, then after two hours, Bob would’ve covered 5(2)=10 miles out of 15.
Therefore, 15-10 or 5 miles still needs to be covered.
To find how long that will take, we can simply divide the distance by the rate.
We are now going at a rate of 3mph. So, 5/3 is about 1.67 hours.
So, it will take another 1.67 hours to complete the hike.
So, the total time it will take is 2+1.67 or abou 3.67 hours. More specifically, it will be 2+5/3 or 11/3 hours.
Option 2) Hiking 4mph the entire way.
The total distance is 15 miles.
If Bob hiked 4mph the entire way, to find how long it will take, we can simply divide the total distance by the rate.
So: 15/4=3.75.
Therefore, it will take 3.75 hours to hike the entire distance going 4mph.
Answer:
1) 11/3 hours or about 3.67 hours.
2) 3.75 hours.
Step-by-step explanation:
Let’s determine the time it will take for Bob to hike for each of the options.
Option 1) Hiking 5mph for 2 hours, then 3mph.
The total distance is 15 miles.
If Bob hiked 5mph for 2 hours, then after two hours, Bob would’ve covered 5(2)=10 miles out of 15.
Therefore, 15-10 or 5 miles still needs to be covered.
To find how long that will take, we can simply divide the distance by the rate.
We are now going at a rate of 3mph. So, 5/3 is about 1.67 hours.
So, it will take another 1.67 hours to complete the hike.
So, the total time it will take is 2+1.67 or abou 3.67 hours. More specifically, it will be 2+5/3 or 11/3 hours.
Option 2) Hiking 4mph the entire way.
The total distance is 15 miles.
If Bob hiked 4mph the entire way, to find how long it will take, we can simply divide the total distance by the rate.
So: 15/4=3.75.
Therefore, it will take 3.75 hours to hike the entire distance going 4mph.

Scientific notation The table shows the amount of money raised by each region the four regions used a total of $ (5.38×10^4) How much money did the West Raise?
9514 1404 393
Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.

Evaluate (2 * x - 4) for x = 2
Answer:
0
Step-by-step explanation:
The expression we are given is (2 * x - 4).
We need to find the value of expression when x = 2.
Let's substitute 2 in as x.
Now our expression is (2 * 2 - 4).
First, let's multiply our 2 with our substituted 2.
1. 2 * 2 = 4
We're left with (4 - 4).
Finally, let's evaluate this expression.
2. (4 - 4) = 0.
Our answer is 0.
So (2 * x - 4) when x = 2 is 0.

A person standing close to the edge on top of a 144-foot building throws a ball vertically upward. The quadratic function h ( t ) = − 16 t 2 + 128 t + 144 models the ball's height about the ground, h ( t ) , in feet, t seconds after it was thrown. What is the maximum height of the ball?
Answer:
400mStep-by-step explanation:
Given the quadratic equation that models the height of the ball above the ground as;
h ( t ) = − 16 t^2 + 128 t + 144
t is in seconds
To get the maximum height of the ball, first we must know the time taken by the ball to reach the maximum height.
Note that the ball has a velocity of zero at its maximum height.
v(t) = dh/dt
v(t) = -32t+ 128
at max height, v(t) = 0
0 = -32t + 128
32t = 128
t = 128/32
t = 4secs
To get the maximum height of the ball, you will substitute t = 4 into the modeled function as shown;
h ( t ) = − 16 t^2 + 128 t + 144
h ( 4 ) = − 16 (4)^2 + 128 (4) + 144
h ( 4 ) = − 256 + 512 + 144
h(4) = 400m
Hence the maximum height of the ball is 400m

2. Find the roots of the following quadratic equations by factorisation:
100x2 - 20x + 1 = 0
Answer:
x = [tex]\frac{1}{10}[/tex]
Step-by-step explanation:
Given
100x² - 20x + 1 = 0 ← this is a perfect square
(10x - 1)² = 0, thus
10x - 1 = 0 ( add 1 to both sides )
10x = 1 ( divide both sides by 10 )
x = [tex]\frac{1}{10}[/tex]
Answer:
Step-by-step explanation:
100x^2-20x+1=0
100x^2-(10+10)X+1=0
100x^2-10x-10x+1=0
10x(10x-1)-1(10x-1)=0
(10x-1)(10x-1)=0

Express 9% as a fraction in simplest form.
Answer:
[tex] \frac{9}{100} [/tex]
Step-by-step explanation:
9% =0.09 =9/100
9/100 cannot be simplified so that's your answer.
9% as a fraction in simplest form is 9/100.
To express 9% as a fraction in simplest form, we first recognize that "percent" means "per hundred."
Thus, 9% is equivalent to 9 per 100 or 9/100.
However, to simplify this fraction further, we find the greatest common divisor (GCD) of the numerator (9) and the denominator (100), which is 1.
Dividing both the numerator and denominator by their GCD yields 9/100.
Hence, 9% as a fraction in simplest form is 9/100.
This means that 9% represents nine parts out of 100 equal parts, making it a concise and clear representation of a percentage as a fraction.
