Amare wants to ride a Ferris wheel that sits four meters above the ground and has a diameter of 50 meters. It takes six minutes to do three revolutions on the Ferris wheel. Complete the function, h(t), which models Amare's height above the ground, in meters, as a function of time, t, in minutes. Assume he enters the ride at the low point when t = 0.
Final answer:
To model Amare's height above the ground as a function of time, use the equation h(t) = 2 + 2 * sin((2 * pi * t) / 6)
Explanation:
To determine a function to model Amare's height above the ground as a function of time, we can use the equation of motion for circular motion. The height of Amare above the ground can be calculated using the equation:
h(t) = r + R * sin(theta)
Where:
h(t) is the height above the ground at time t
r is the radius of the wheel (half the diameter)
R is the maximum height above the ground (given as 4 meters)
theta is the angle in radians, which is related to time by the formula theta = (2 * pi * t) / T, where T is the time for one revolution (given as 6 minutes)
Putting all these values into the equation, we get:
h(t) = 2 + 2 * sin((2 * pi * t) / 6)

Red and gray bricks were used to build a decorative wall. The number of red bricks number of gray bricks was Start Fraction 5 over 2 End Fraction . There were 175 bricks used in all. How many red bricks were used?
Final answer:
To find the number of red bricks used, the ratio 5:2 is represented as 5x:2x. Solving the equation 7x = 175 gives x = 25. Multiplying this by 5, there were 125 red bricks used.
Explanation:
The question asks us to find the number of red bricks used to build a wall when the ratio of red bricks to gray bricks is 5:2 and there were 175 bricks used in total. To solve this, we set up the ratio 5x:2x where 'x' represents the multiplier for the number of bricks, and the sum of red and gray bricks which is 5x + 2x equals the total number of bricks, 175.
First, we combine like terms: 5x + 2x = 7x. Next, we solve for 'x' by dividing both sides of the equation by 7.
7x = 175
x = 175 / 7
x = 25
We then multiply this value by 5 to find the number of red bricks: 5 * 25 = 125.
Therefore, 125 red bricks were used to build the wall.
The volume of right circular cylinder a is 22 cubic centimeters. what is the volume, in cubic centimeters with twice the radius and half the height?
To find the volume of the new cylinder with twice the radius and half the height, use the formula for the volume of a cylinder and substitute the new values. The volume of the new cylinder is also 22 cubic centimeters.
Explanation:To find the volume of the new cylinder with twice the radius and half the height, we can use the formula for the volume of a cylinder: V = πr2h.
First, we double the radius of the original cylinder. Let's say the original radius is r. The new radius would be 2r.
Next, we halve the height of the original cylinder. Let's say the original height is h. The new height would be h/2.
Substituting these values into the volume formula, we get the volume of the new cylinder as V = π(2r)2(h/2)=4πr2(h/2)=2πr2h.
So, the volume of the new cylinder is also 22 cubic centimeters.

Answer:
A: The variable x in the first equation has a coefficient of one so there will be fewer steps to the solution.
Step-by-step explanation:
I got it right on Edge
The value of x and y is 1 and 0 for the given system of equations.
And, the reason Max gives for his statement that " the variable x in the first equation has coefficient of one so there will be fewer steps to the solution".
What is system of equations?A system of equations is a set of two or more equations with the same variables. A solution to a system of equations is a set of values for the variable that satisfy all the equations simultaneously.
What is substitution method?The substitution method can be defined as a way to solve a linear system algebraically. In this method we substitute one y-value with the other. To put it simply, the method involves finding the value of the x-variable in terms of the y-variable.
According to the given question.
We have system of equations.
x - 3y = 1
and 7x + 2y = 7
To solve the above system of equations we use substitution method.
Since, the first the corffeficient of x in first equation is 1. So we will use the value of x of equation x -3y = 1 to substitute in second equation. Because it require fewer steps to get the solution.
So,
From x - 3y = 1
We cay say that
x = 1 + 3y
Substitute the value of x in 7x + 2y = 7.
⇒ 7(1 + 3y) + 2y = 7
⇒ 7 + 21y +2y = 7
⇒ 7 + 23y = 7
⇒ 23y = 7-7
⇒ 23y = 0
⇒ y = 0
Again susbstitute the value of y in x =1 + 3y.
⇒ x = 1 + 3(0)
⇒ x = 1
Hence, the value of x and y is 1 and 0 for the given system of equations.
Therefore, the reason Max gives for his statement that " the variable x in the first equation has coefficient of one so there will be fewer steps to the solution".

Solve this problem. Find the number of gallons of paint needed to cover all four sides four sides) of the building shown with two coats of paint if one gallon covers 350 square feet. Disregard windows and doors. Round to the nearest gallon.
Answer: the answer is 3 gallons of paint is required to paint the building.
Step-by-step explanation:
The area to be painted is:
= 2× [Area of Rectangle with dimensions 20 ft.×10 ft.+Area of triangle with height 5 ft. and base 20 ft.+Area of rectangle with dimensions 24 ft. and 10 ft.]
=2×[20×10+(1/2)×5×20+24×10]
=2×[200+50+240]
=2×490
=980 square ft.
Hence, the area to be painted=980 square feet.
Now, amount of paint require to cover 350 square feet=1 gallon.
i.e. 1 square feet requires=1/350 gallon of paint.
⇒ 980 square feet requires=980/350=2.8 gallons of paint.
Hence, to the nearest gallon we could say that:
3 gallons of paint is required to paint the building.

[tex]\[ P(\text{not rolling a 2, 4, or 5}) = \frac{3}{6} = \frac{1}{2} \][/tex]
Step 3: Calculate the odds for rolling a 2, 4, or 5.
Odds for an event are given by the ratio of the number of favorable outcomes to the number of unfavorable outcomes.
[tex]\[ \text{Odds for rolling a 2, 4, or 5} = \frac{\text{Number of favorable outcomes}}{\text{Number of unfavorable outcomes}} = \frac{3}{3} = 1:1 \][/tex]
