What is the volume of this sphere?
Use a 3.14 and round your answer to the nearest hundredth.
6 yd
Answers
Answer:
Volume = 904.78 yards
Step-by-step explanation:
The formula for a sphere is:
V=4/3πr³
Since we already know that the radius is 3 yards and that π is 3.14 all we have to do is plug in the numbers.
V=4/3(3.14)(6)³
V=4/3(3.14)(216)
V=4.1897(216)
V≈904.78 yards
Can someone help me answer this please?
Answers
Answer:
105 minutes
Step-by-step explanation:
The pond is a prism. Its volume is the area of the trapezoidal base (the front and back faces) multiplied by the height (the 1 m edge).
Area of base of pond (front face) = (1/2)(B + b)h
Base = (1/2)(1.5 m + 0.6 m)(2 m) [Here, height is the height oif the trapezoid, so it is 2 m]
Base = 2.1 m²
Volume = Base × Height
Volume = 2.1 m² × 1 m [Here, height is the height of the prism, so it is 1 m]
Volume = 2.1 m³
The volume of the upper 30 cm (= 0.3 m) of the pond is:
V = LWH
V = 2 m × 1 m × 0.3 m
V = 0.6 m³
The volume of water decreased 0.6 m³ in 30 minutes.
In 60 minutes, it would decrease by 1.2 m³.
60 minutes = 1 hour
The flow rate is 1.2 m³ / hour.
The total volume of the pond is 2.1 m³.
Emptying out the pond completely means removing 2.1 m³ of water at the flow rate of 1.2 m³/hour.
flow rate = volume/time
time × flow rate = volume
time = volume / flow rate
time = 2.1 m³ / 1.2 m³/hour = 1.75 hour
time = 1.75 hour × 60 minutes/hour = 105 minutes
Answer: 105 minutes
Write an equation of a line that passes through -4, -4 and 4,4
Answers
Answer: y=x
Step-by-step explanation:
The slope is (y2-y1)/(x2-x1) = 8/8 = 1
Plugging it into the equation y = mx+b:
y = x + b
Plugging in one of the coordinates:
4 = 4+b
b = 0
Therefore, the equation of the line is y=x

Answers
Answer:
y = 28°
Step-by-step explanation:
The triangle is a right triangle which has 90 degrees.
The 3x falls under 90 degrees.
So:
→ 2y + 90° + 34° = 180°
→ 2y = 180° - 124°
→ 2y = 56°
→ y = 28°
Triangle
XYZ = right triangle
3x = 90°
X + Y + Z = 180°
34° + 3x + 2y = 180°
34° + 90° + 2y = 180°
2y = 180° - (34° + 90°)
2y = 56°
y = 28°

The owner of an orange grove must decide when to pick one variety of oranges. She can sell them for $24 a bushel if she sells them now, with each tree yielding an average of 4 bushels. The yield increases by half a bushel per week for the next 5 weeks, but the price per bushel decreases by $1.50 per bushel each week. In how many weeks should the oranges be picked for maximum return?
Answers
Answer:
4
Step-by-step explanation:
Let's say the amount of bushes sold (yield) is b, and the price per bushel is p.
When calculating total revenue, we want to multiply price by quantity. Quantity here is b, and price is p. Therefore, p*q = revenue = return.
Let's say that the amount of weeks is w.
Price after w weeks = 24 - 1.50 for each week = 24 - 1.50w
Yield after w weeks = 4 + 0.5 for each week = 4 + 0.5w
Revenue after w weeks = p * b = (24-1.50w) * (4+0.5w) = 96 - 6w + 12w - 0.75w² = -0.75w²+6w + 96.
We want to maximize revenue. First, we can find when the derivative of the function is 0.
d/dw(-0.75w²+6w + 96) = -1.5w + 6 = 0
subtract 6 from both sides
-1.5w = -6
divide both sides by -1.5 to isolate w
w = 4
plug that into our equation
-0.75(4)²+6(4) + 96 = -12 + 24 + 96 = 108
Because this function has a negative coefficient for the w², we can say that it is a parabola opening up downward, so when the derivative = 0, we have found the maximum of the function. Therefore, 4 is our answer

Jackson made a drawing for his residence including a villa and a garden, as in the given figure. Using the scale drawing, what is the perimeter of the villa in real life?
Answers
Answer:
60 meters.
Step-by-step explanation:
Here the villa has length of 6 cm and breadth of 4 cm
Find perimeter using:
2(length + breadth)
2(6 + 4)
20 cm
Here in scale the drawing perimeter is 20 cm
3 meter = 300 cm ......this is for real.
1 cm here --> 20 cm
300 cm in real --> (20*300) cm
Real perimeter = 6000 cm
If 6000 cm converted to m:
(6000/100) = 60 meters.
Find perimeter using:
[tex]2(length + breadth)[/tex]
[tex]2(6+4)[/tex]

Kira is a lovable dog who is full of energy. Her owner thought it would be fun to train her by throwing a frisbee for her to catch. When the frisbee is thrown, it follows a parabolic path that is modeled by the function h(t) = – 0.145t2 + 0.019t + 5.5. How many seconds will it take for the frisbee to hit the ground?
–6.2 seconds
–6.1 seconds
5.5 seconds
6.2 seconds
Answers
Answer:
6.2 seconds
Explanation:
Given function: h(t) = – 0.145t² + 0.019t + 5.5
Here h(t) which determines the height, when Frisbee touches the ground, the height shall be 0.
solve the quadratic equation:
using the formula: [tex]\left[\begin{array}{ccc} t = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a}\end{array}\right][/tex]
Solving steps:
→ –0.145t² + 0.019t + 5.5 = 0
→ [–0.145t² + 0.019t + 5.5 = 0 ]* 100
→ -145t² + 19t + 5500 = 0
→ [tex]t = \frac{ -19 \pm \sqrt{19^2 - 4 ( -145)(5500)}}{2(-145)}[/tex]
→ [tex]t_1=\frac{-19+\sqrt{3190361}}{2\left(-145\right)},\:t_2=\frac{-19-\sqrt{3190361}}{2\left(-145\right)}[/tex]
→ [tex]t = -6.09[/tex] , [tex]t = 6.2[/tex]
→ [tex]t = 6.2[/tex]
Time cannot be negative here.
So time taken: 6.2 seconds.
Answer:
D. 6.2 secondsStep-by-step explanation:
When the frisbee hits the ground, the value of h is zero.
Find the time required:
– 0.145t² + 0.019t + 5.5 = 0145t² - 19t - 5500 = 0t = (19 + √(19² + 4*145*5500))/290 = (19 + 1786,1)/290 = 6.2 seconds (rounded)Note, taking positive root only as time is never negative
