Hello,

We must calculate the volume of water in one hour.

V=15000*PI*0.07²=230,9070600... m^3/h.

Volume of the pond=50*44*.21=462 m^3

Time=462 m^3/ 230.907... m^3/h=2,0008... h≈2 h

If there are twice as many bicycles as scooters and there are 945 vehicles in total. How many bicycles and scooters are there in
alexandr402 [8]

Answer:

Bicycles = 315

Scooters = 630, basic mathematics. The most effective method for these questions is substitution. But I might have intermingled them so double check

A line passes through (-1,5) and (1,3) what is the equation of the line
chubhunter [2.5K]

Answer:

y = -x + 4

Step-by-step explanation:

(-1,5)...x1 = -1 and y1 = 5

(1,3)....x2 = 1 and y2 = 3

slope(m) = (y2 - y1) / (x2 - x1) = (3 - 5) / (1 - (-1) = -2 / (1 + 1) = -2/2 = -1

y = mx + b

slope(m) = -1

u can use either of ur points...I will use (1,3)...x = 1 and y = 3

now we sub and find b, the y int

3 = -1(1) + b

3 = -1 + b

3 + 1 = b

4 = b

ur equation is : y = -x + 4 <===

Answer:

B) 10 cm

Step-by-step explanation:

Hello!

We can use the Pythagorean theorem to solve for the hypotenuse.

Formula: a^2 + b^2 = c^2

  • a = leg
  • b = leg
  • c = hypotenuse

We can plug in the values for each leg to solve for the hypotenuse.

<h3>Solve for c</h3>
  • a^2 + b^2 = c^2
  • 6^2 + 8^2 = c^2
  • 36 + 64 = c^2
  • 100 = c^2
  • \sqrt{100} = \sqrt{c^2}
  • 10 = c

The answer is Option B: 10 cm
