8 0

Answer:

Perimeter: 20, Area: 21

Step-by-step explanation:

  • Based on points (2,6) and (5,6) :  w = 5 - 2 = 3
  • Base on points (5,6) and (5,-1 ): l = 6 - (-1) = 7

  • Perimeter: 2 x (3 + 7) = 20
  • Area: 3 x 7 = 21

7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1

 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} 

 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1

 Answer:
 
7 times 1/7 equals 1

The wind force f on a sail varies jointly as the area a of the sail and the square of the wind speed w.
blondinia [14]

Answer:

  122.5 lbs

Step-by-step explanation:

The relation between force, wind speed, and area can be written ...

  f = ks²a

for some wind speed s and area a.

__

The constant of proportionality, k, can be found from the given data.

  64.8 = k(18²)(500) . . . force in pounds, area in square feet, speed in mph

  k = 64.8/(324×500) = 0.0004

__

Using the equation with the second set of data, we have ...

  f = 0.0004(35²)(250) = 122.5 . . . . pounds

The force on the 250 square foot sail would be 122.5 pounds.
