Answer:
11 feet away.
Step-by-step explanation:
Given:
A water and sprinkle our sins water out in a circular pattern
Area formed by the watering pattern is 379.94 square feet
To find:
How many feet away can it spread water means we have to find distance from the middle point to the last end of circular pattern of water sprinkling (radius of a circle) = ?
solution:
By using ,Area of a circle = 
Area of a circle = 379.94 square feet (given)
= 
Dividing both side by 3.14
Taking square root both side
![r = \sqrt[2]{11\times11}](https://tex.z-dn.net/?f=r%20%3D%20%5Csqrt%5B2%5D%7B11%5Ctimes11%7D)
(Taking common)
Therefore, radius = 11
Thus, it can spread water 11 feet away.
Respuesta:
3,2 metros
Explicación paso a paso:
Área del trapecio:
A = 1/2 (a + b) h
h = altura; ayb son las bases
Área, A = 60
Sea una base más pequeña = a = 18;
b = 18 + 3/2 = 19,5
La altura se puede calcular así;
60 = 1/2 (18 + 19,5) h
60 * 2 = 37,5 horas
120 = 37,5 h
h = 120 / 37,5
h = 3,2 metros
Answer:
The speed on motorboat is 20 mph
Step-by-step explanation:
here, we want to find the speed on the motorboat
if he has a speed of x mph on the motor boat, his speed on the ski will be (x + 10) mph
The total hours is 4 hours
Mathematically; speed = distance/time
Time on ski is 27/x+ 10
Time on motor boat is 62/x
The addition of both is 4
Thus;
27/(x + 10) + 62/x = 4
27(x) + 62(x + 10) = 4(x)(x + 10)
27x + 62x + 620 = 4(x^2 + 10x)
89x + 620 = 4x^2 + 40x
4x^2 -49x-620 = 0
using the quadratic formula;
{-b ± √(b^2-4ac)}/2a
where a = 4, b = -49 and c = -620
= 49 ± √(-49)^2-4(4)(-620)/8
So we have
49+ 111/8 or 49-111/8
Speed cannot be negative
(49 + 111)/8
= 20 mph
Well if you take the room being 20 x 24. Thats 480 feet. But you want how large in 1/2 inch. 1/2 inch is 1/24 of a foot. So if we take 480 feet being 1 and times it by 24. (480 x 24) You get 11,520 half inches. Brainliest would be much appreciated if you feel its deserved.
