Answer:
C
Step-by-step explanation:
let x be number of adults and y the number of underage , then
x + y = 350 → (1)
6x + 4y = 1600 → (2)
multiplying (1) by - 4 and adding to (2) will eliminate y
- 4x - 4y = - 1400 → (3)
add (2) and (3) term by term to eliminate y
(6x - 4x) + (4y - 4y) = 1600 - 1400
2x + 0 = 200
2x = 200 ( divide both sides by 2 )
x = 100
the number of adults who attended is 100

Answer:
50.24
Step-by-step explanation:
4²=16
16×3.14=50.24
Firstly, we must use the equation to solving a circle which is [tex]A = \pi r^2[/tex]. Since we already know pi (3.14) and the radius (4), we must plug the numbers into the formula. Here is how it should look like with the plug-ins: [tex]A = 3.14 * 4^2[/tex].
Next, we solve the formula. After solving, we get 50.24. The final answer to the problem is 50.24 inches squared.
64x=8
What is the value of x that makes the equation true
Answer:
fraction:
x = [tex]\frac{1}{8}[/tex]
decimal:
x = 0.125
Step-by-step explanation:
64 divided by 8 = 8
[tex]\frac{64}{8}[/tex] = 8
So if youre changing this to multiplication you want to multiply by [tex]\frac{1}{8}[/tex]
[tex]\frac{64}{1}[/tex] * ( [tex]\frac{1}{8}[/tex] )= [tex]\frac{64}{8}[/tex] = [tex]\frac{8}{1}[/tex] = 8
Answer:
fraction:
x = \frac{1}{8}81
decimal:
x = 0.125
Step-by-step explanation:
64 divided by 8 = 8
\frac{64}{8}864 = 8
So if youre changing this to multiplication you want to multiply by \frac{1}{8}81
\frac{64}{1}164 * ( \frac{1}{8}81 )= \frac{64}{8}864 = \frac{8}{1}18 = 8
A company is going to make an oil container in the shape of a cylinder. As shown below, the container will have a height of 8 m and a radius of 6 m The container will be made from steel (including its top and bottom). Suppose the total cost of the steel will be 17,408.16 How much will the steel cost per square meter? Use for 3.14 and do not round your answer.
Step-by-step explanation:
Total surface area of a cylinder =
Area of curved surface (the round body) + area of two circular covers ( the top and bottom cover)
= 2πrh + 2πr²
= 2πr(h+r)
= 2 • 3.14• 6•(8+6)
= 527.52 m²
Cost per m²
= 17,408.16/527.52

How high will the firework be when it explodes? (Look at Photo)
Answer:
606 feet
Step-by-step explanation:
The fireword has a 5-second fuse, meaning that's how long it will take to explode.
Given the polynomial -16t² + 200t + 6, where t is the time in seconds
We need to subsitute 5 sec. (as stated in the question) for t in the polynomial, to find how high the fireworks will be when it explodes :
-16t² + 200t + 6 <== substitute 5 for t
-16(5)² + 200(5) + 6 <== square the exponent first
-16(25) + 1000 + 6 <== multiply
-400 + 1000 + 6 <== add
-400 + 1006 <== add
606 feet <== final answer
This means that it will be 606 feet high before it explodes.

Answer:
30.84 in
Step-by-step explanation:
First we find the circumference, which is d(pi), 12(3.14) which = 37.68. Then since the circle is a semicircle, we divide 37.68 by 2=18.84 in. Then we have to add 12 since the circle is cut in half, so add 12 to get 30.84.
A large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and height of 3',
and the other with a right triangle with a hypotenuse of 5' and a side of 3'. What is the probability of
throwing a drop of paint into one of the triangles?
The probability of throwing a drop of paint into one of the triangles is 3.96% if a large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and a height of 3', and the other with a right triangle with a hypotenuse of 5' and a side of 3'
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Total area of the canvas = 9' x 21' = 189 square units
This area is representing the total outcome = 189
Total favorable outcome = area of first triangle + area of the second
triangle
Area of the first triangle = (1/2)(1x3) = 3/2 square units
From the Pythagoras theorem:
Height = √(5² - 3²) = 4'
Area of the second triangle = (1/2)(3x4) = 6 square units
Total favourable outcome = 3/2 + 6 = 15/2
Now the probability:
[tex]= \frac{\frac{15}{2} }{189}[/tex]
= 15/378
= 0.0396×100
= 3.96%
Thus, the probability of throwing a drop of paint into one of the triangles is 3.96% if a large white canvas, 9' x 21', has two triangles painted on it, one with a base of a 1' and a height of 3', and the other with a right triangle with a hypotenuse of 5' and a side of 3'

Answer:
39°
Step-by-step explanation:
To answer this question it's important to remember that all triangles have 3 angles which sum to 180. This means that we can set up an equation to find the missing angle
Create the equation
[tex]39+102+x=180[/tex]Combine like terms
[tex]141+x=180[/tex]Subtract 141 from both sides
[tex]x=39[/tex]This means that the missing angle is 39 degrees. Since two of the angles are equal to 39, this also means that this triangle is isosceles.
pls help :) determine which function has a greater rate and explain how you know.

function 2:
x y
0 1
1 0.8
2 0.64

Using exponential function concepts, it is found that the second function has a greater rate, as 0.8 > 0.2.
What is an exponential function?It is modeled by:
[tex]y = ab^x[/tex]
In which:
a is the initial value, that is, y when x = 0.b is the rate of change, as a decimal.Function 1 is given by:
[tex]y = 2(0.2)^x[/tex]
Hence the rate is b = 0.2.
Considering the values on the table, function 2 is given by:
[tex]y = (0.8)^x[/tex]
Hence the rate is b = 0.8.
Hence, the second function has a greater rate, as 0.8 > 0.2.

What is the answer and how to solve?
Two gears are in mesh. The first gear is rotating at 60 rpm and has 23 teeth. The second gear is rotating at 5 rpm. How many teeth does the second gear have
The second gear has approximately 2 teeth.
To find the number of teeth on the second gear, we can use the concept of gear ratios. The gear ratio is the ratio of the number of teeth on the first gear to the number of teeth on the second gear. It is equal to the ratio of their rotational speeds.
Gear Ratio = (Number of Teeth on First Gear) / (Number of Teeth on Second Gear)
Given that the first gear is rotating at 60 rpm and has 23 teeth, and the second gear is rotating at 5 rpm, we can set up the gear ratio equation:
60 rpm (First Gear) / 5 rpm (Second Gear) = 23 teeth (First Gear) / X teeth (Second Gear)
Now, let's solve for X (the number of teeth on the second gear):
X = (23 teeth × 5 rpm) / 60 rpm
X = 115 teeth / 60 rpm
X ≈ 1.92 teeth
Since you cannot have a fraction of a tooth, you would generally round up to the nearest whole number.
Thus, the second gear has approximately 2 teeth. However, it's important to note that it's not practical to have a gear with only 2 teeth, as it wouldn't effectively mesh with the first gear.
In real-world applications, gears typically have a higher number of teeth for smooth and efficient operation. So, in practice, the second gear would likely have a different, more practical number of teeth.
