Ryan and his brother are at a carnival. They separate from each other at the ferris wheel at 1:00 PM, and they agree that they will each meet back at the ferris wheel from time to time to see whether the other is ready to leave. Ryan checks the ferris wheel every 15 minutes. His brother checks in every 24 minutes. At what time will they meet at the ferris wheel again. (Hint: Don't forget you're looking for a time)
Answers
Answer:
3:00pmStep-by-step explanation:
The idea hear is to find the least common multiples of 15 and 24
Given that they separated at exactly 1:00pm
the multiples are
15= 15,30,45,60,75,90,105,120
24= 24, 48,72,96,120
the multiples common is 120
Therefore they will meet in 120minute, which is 2 hours time \
hence the time will be 3:00pm

For a school art project, Kali has 604 square tiles measuring 1 inch on each side. She plans to use the tiles to completely cover the box in the shape of a rectangular prism shown below. (FORMULA: Surface Area = 2lw + 2lh + 2wh) Which statement about Kali's tiles is true? Group of answer choices Kali needs 476 more tiles to completely cover the box. Kali needs 104 more tiles to completely cover the box. Kali will have 534 tiles left after completely covering the box. Kali will have 250 tiles left after comp
Answers
Answer:
Kali needs 104 more tiles to completely cover the box.
Step-by-step explanation:
Length of box = 20 in
Breadth of box = 6 in
Height of box= 9 in
Total surface area of box = 2lw + 2lh + 2wh
Total surface area of box = 2(20)(6) + 2(20)(9) + 2(6)(9)
Total surface area of box = 708 sq. in.
Side of tile = 1 in
Area of 1 tile = [tex]Side^2 = 1^2 = 1 sq. in[/tex]
Area of 604 tiles = 604 sq. in.
Area remain uncovered = 708 - 604 = 104 sq.in.
So, Kali needs 104 more tiles to completely cover the box.

Part A: An archer shoots an arrow into the sky where the motion of the arrow can be modeled by the equation() = −5^2 + 20 + 4. Where t is time in seconds and f(t) is height in feet. Find how long it will take the arrow to hit the ground using an algebraic method. Round to the nearest tenth if necessary. Show all of your reasoning used with this algebraic method.
Part B: Using the information in Part A, find how high the arrow will go at its maximum height, and how long it takes for this to occur using an algebraic method. Show all of your reasoning used with this algebraic method. Round to the nearest tenth if necessary.
Answers
Answer:
The arrow will take 4.19 seconds to hit the ground
The arrow will go 24 feet to reach its maximum height and it takes 2 seconds to reach this height
Step-by-step explanation:
The quadratic function is f(t) = -5t² + 20t + 4, where
f(t) is the height in feet
t is the time in seconds
If the arrow hit the ground that means h(t) = 0
→ Substitute h(t) by 0 and use the quadratic formula to find t
∵ h(t) = 0
∴ 0 = -5t² + 20t + 4
→ Switch the two sides
∴ -5t² + 20t + 4 = 0
→ Multiply all terms by -1 to make the coefficient of t² positive
∴ 5t² - 20t - 4 = 0
→ The quadratic formula is [tex]t=\frac{-b+-\sqrt{b^{2}-4ac}}{2a}[/tex] , where
a is the coefficient of t²b is the coefficient of tc is the numerical term∵ a = 5, b = -20, c = -4
∴ [tex]t=\frac{-5+-\sqrt{(-20)^{2}-4(5)(-4)}}{2(5)}[/tex]
∴ [tex]t=\frac{-5+-\sqrt{400+80}}{10}[/tex]
→ Find the values of t in decimal
∴ t = 4.19 seconds OR t = -0.19 ⇒ refused because it is negative
∴ The arrow will take 4.19 seconds to hit the ground
The graph of this quadratic function is a parabola with maximum vertex (h, k), where
h = [tex]\frac{-b}{2a}[/tex]k = f(h)To find the maximum height and the time taking for this to occur find h and k where k is the maximum height and h is the time for this to occur
∵ f(t) = -5t² + 20t + 4
∵ a = -5 and b = 20
∴ h = [tex]-\frac{20}{2(-5)}=-\frac{20}{-10}=2[/tex]
∴ The time for the maximum height is 2 seconds
→ Now use it to find k
∵ k = f(h)
∴ k = f(2)
∵ f(2) = -5(2)²+ 20(2) + 4
∴ f(2) = -5(4) + 40 + 4
∴ f(2) = -20 + 40 + 4
∴ f(2) = 24
∴ k = 24
∴ The maximum height is 24 feet
The arrow will go 24 feet to reach its maximum height and it takes 2 seconds to reach this height

Which equation shows a proportional relationship between x and y?
y = 16
y = 7x
y=−7x−2
y = 9x + 1
Answers
The equation that shows a proportional relationship is y = 7x.
How to find the equation that is proportional?Two variables have a proportional relationship if all the ratios of the variables are equivalent.
In other words, a proportional relationship is one in which two quantities vary directly with each other.
Therefore, a proportional relationship can be represented as y = kx.
where
k = constant of proportionalitythe variables are x and yTherefore, y varies directly as x in a proportional relationship.
Hence, the equation that shows proportional relationship is y = 7x as 7 is the constant of proportionality. y and x are the variables.

In his motorboat, Bill Ruhberg travels upstream at top speed to his favorite fishing spot, a distance of 264 mi, in 6 hr. Returning, he finds that the trip downstream, still at top speed, takes only 5.5 hr. Find the rate of Bill's boat and the speed of the current. Let x = the rate of the boat in still water and y = the rate of the current.
Answers
Answer:
The values are [tex]x = 46 miles /hr [/tex]
[tex]y = 4 \ miles / hr[/tex]
Step-by-step explanation:
From the question we are told that
The distance covered is d = 264 miles
The time taken is [tex]t_1 = 6 hours[/tex]
The time taken for the return trip is [tex]t_2 = 5.5 \ hours[/tex]
Generally during the trip toward fishing spot , the velocity is mathematically represented as
[tex]v_t = \frac{d}{t_1 } = x - y[/tex]
=> [tex]v_t = \frac{264}{6 } = x - y[/tex]
=> [tex]x - y = 44 \cdots 1 [/tex]
Generally during the return trip , the velocity is mathematically represented as
[tex]v_r = \frac{d}{t_2} = x+ y[/tex]
=> [tex]v_r = \frac{264}{5.5} = x+ y[/tex]
=> [tex]48 = x+ y\cdots 2[/tex]
add equation 1 and 2
[tex]2x = 92[/tex]
=> [tex]x = 46 miles /hr [/tex]
substituting this into equation 1
[tex] 46 - y = 44 \cdots 1 [/tex]
=> [tex]y = 4 \ miles / hr[/tex]

Determine the given equation is a linear equation write yes or no. If yes, write the equation in standard form.
7n - 8m = 4 - 2m.
Use Standard form
Answers
Answer:
The equation is linear. Standard form:
7n - 6m - 4 =0
Step-by-step explanation:
Linear Equations
The linear equations are identified because all terms form a polynomial of degree 1 or zero (no variable).
The standard form of a linear equation is:
ax+by+cz+d=0
where x, y, z are the variables, and a,b,c are constants.
The equation:
7n - 8m = 4 - 2m
Is linear, both variables have an exponent of 1 and there is an independent term. Moving all terms to the left side:
7n - 8m - 4 + 2m =0
Simplifying:
7n - 6m - 4 =0
