Answer:
about 28
Step-by-step explanation:
you have to use the sine rule = side you know * ( sin of angle opposing the side you want to know / sin of angle opposing the side you know)
AB = 19* (sin 75/ sin ( 180 -75-64) )
AB = 19 * ( sin 75 / sin 41) ≈ 27.9739...
The school band is selling tickets for a chance to win an Ipad. Lucy bought 20 out of the 200 tickets sold. What percent chance does Lucy have of winning the Ipad?
Answer:
She has a 10% chance.
Step-by-step explanation:
To make this easier on our selves let's divide each by 2.
That makes Lucy hold 10 tickets for the 100 tickets available.
10/100 = 10%
Any numerator that is over 100 is the percentage
Say if I had 52/100 I would have 52%
Answer:
Lucy has a 10% chance of winning the Ipad.
Step-by-step explanation:
divide 20 by 200: 20/200= 0.1
now to find the percent multiply the decimal by 100
0.1 * 100= 10
She has a 10% chance of winning the Ipad

Does the location of the first aid station actually fall in the middle of the park? Provide mathematical calculations to support your answer.
Answer:
The first aid station is at the middle of the park.
Step-by-step explanation:
Given
[tex](0,0) \to[/tex] Origin of Fun
[tex](-7, 6) \to[/tex] Quadratics in Motion
[tex](-2, 14) \to[/tex]Towers of Trigonometry
[tex](5,8) \to[/tex] The Food Equation
[tex](-1,7)\to[/tex] First aid station
Solving (a): Plot the above points
See attachment for plot
Solving (b): Determine if the first aid station is at the center of the park
From the plot, we have the opposite points to be:
(1) [tex](0,0)[/tex] and [tex](-2, 14)[/tex]
(2) [tex](5,8)[/tex] and [tex](-7, 6)[/tex]
Calculate midpoint using:
[tex]M = \frac{1}{2}(x_1 + x_2, y_1 + y_2)[/tex]
For (1):
[tex]M = \frac{1}{2}(0 -2, 0 + 14)[/tex]
[tex]M = \frac{1}{2}(-2,14)[/tex]
[tex]M = (-1,7)[/tex]
For (2):
[tex]M = \frac{1}{2}(5 -7, 8 + 6)[/tex]
[tex]M = \frac{1}{2}(-2,14)[/tex]
[tex]M = (-1,7)[/tex]
From the above computation, we have midpoint to be:
[tex]M = (-1,7)[/tex]
Given that:
[tex](-1,7)\to[/tex] First aid station
We can conclude that the first aid station is at the middle of the park.

The width of a rectangle measures (8p+5) centimeters, and its length measures (4p+4) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?
1. 24p+18
2. 8+13p
3. 9+12p
4. 26p+16
Thx if u help>3
Answer:
1. 24p + 18
Step-by-step explanation:
One of the formulas used to find the perimeter of a rectangle is:
P = 2(l + w)
Where P is the perimeter, l is the length, and w is the width. We can substitute in the given values:
P = 2[(4p + 4) + (8p + 5)]
Now we can combine the like terms:
P = 2[12p + 9]
And simplify:
P = 24p + 18
This is the same as option 1.

a car uses 32 L of gas to travel 450 KM. how many liters would be required to drive 800 km (to the nearest tenth)?
Answer: 56.88 L
Explanation:
Let L represents number of liters
A Car uses 32 L of gas to travel 450 km.
Write a proportion for the problem using rates.
450/32 = 800/L
Cross product is 450*L = 800*32
450L = 25600
Divide each side by 450.
450L/450 = 25600/450
L = 56.88

Answer:

Step-by-step explanation:
y = 3x + 4
plug in (-2, -2)
-2 = -6 +4
-2 = -2
y = 6x + 10
plug in (-2, -2)
-2 = -12 + 10
-2 = -2
Answer:
B
Step-by-step explanation:
Given the 2 equations
y = 3x + 4 → (1)
y = 6x + 10 → (2)
Substitute y = 6x + 10 into (1)
6x + 10 = 3x + 4 ( subtract 3x from both sides )
3x + 10 = 4 ( subtract 10 from both sides )
3x = - 6 ( divide both sides by 3 )
x = - 2
substitute x = - 2 into either of the 2 equations and evaluate for y
Substituting into (1)
y = 3(- 2) + 4 = - 6 + 4 = - 2
solution is (- 2, - 2 ) → B

The function g(t) = -16t2 + vt + h represents the height of an object, g, in feet above the ground in relation to the time, t, in seconds, since the object was thrown into the air with an initial velocity of v feet per second at an initial velocity of v feet per second at an initial height of h feet.
A model rocket is launched off the ground at an initial velocity of 80 feet per second.
Part A: Write a function that can be used to describe the flight of the model rocket.
A. g(t) = -16t^2 + 80t + 80
B. g(t) = -16t^2 + 80
C. g(t) = -16t^2 + t + 80
D. g(t) = -16t^2 + 80t

56. An equation Is shown.
x? + 8x + 19 = 0
Part A: What is an equivalent equation that results from completing the square?
Answer:
(x + 4)^2 + 3 = 0
Step-by-step explanation:
When you multiply out (a + b)^2, you get a^2 + 2ab + b^2. We already know the a^2 term, which is x^2. We can deduct the first term of the square is x because x * x is x^2, and x would correspond with a. Next, we can connect the 2ab term with 8x, as it includes the variable x.
2ab = 8x
We have established a = x, so:
2xb = 8x
b = 4
We can put this together to get the square:
(x^2 + 8x + 16) + 3 = 0
(the three is added to get a last term of 19 in the given equation)
When we factor the square, it turns out as:
(x + 4)^2 + 3 = 0

A coke can and a monster can are each in the shape of a right circular cylinder. The cans have the same radius but the height of the monster can is 2 times the height of the coke can. What is the ratio of the volume of the coke can to the volume of the monster can
Answer:
1 : 8
Step-by-step explanation:
Given the height of 2 similar cylinders = a : b , then
ratio of volumes = a³ : b³
Here the ratio of heights = 1 : 2
ratio of volumes = 1³ : 2³ = 1 : 8

This section of a concrete skateboard ramp has the shape of a triangular prism. Find the volume of the triangular prism. Find the value of the concrete used in the ramp if the cost of concrete is $3.00 per cubic foot. 6ft 6ft 10.2ft
Answer:
$550.80
Step-by-step explanation:
Value of concrete used = volume of the prism x cost per cubic foot
volume of the prism = base area x height
the base is in the shape of a triangle
Area of a triangle = (1/2) x base x height = 1/2 x 6 x 6 = 18
Volume of the prism = 18 x 10.2 = 183.6 ft^3
183.6 x 3 = $550.80
