Answer:

With wind = 1000 km /hr

In calm air = 800 km/hr

Step-by-step explanation:

With wind :

Distance traveled = 1500 km

Time taken = 1.5 hours

Speed of plane in air :

Speed = distance / time

Speed = 1500 km / 1.5 hours

Speed = 100 km pe hour

In calm air :

Time taken = 1.875 hours

Distance = 1500 km

Speed of wind in calm air :

Distance / time

1500 km / 1.875

= 800 km/hr

13. The perimeter P (in yards) of a soccer field is represented by the formula P = 24 + 2w,
rjkz [21]

Answer:

w = \frac{1}{2}(P - 24)

w = 153\ yards

Step-by-step explanation:

Given

P = 24 + 2w

Require

Solving (a):

P = 24 + 2w

Subtract 24 from both sides

P-24 = 24-24 + 2w

P-24 = 2w

Divide both sides by 2

\frac{1}{2}(P - 24) = \frac{2w}{2}

\frac{1}{2}(P - 24) = w

w = \frac{1}{2}(P - 24)

Solving (b):

Substitute 330 for P un the expression in (1)

w = \frac{1}{2}(330 - 24)

Evaluate the bracket

w = \frac{1}{2}(306)

w = 153\ yards

Dani uses the table to help her convert measurements when she is sewing
Aleks [24]
The first thing we should do is see what relationship we have:
 Table is feet to yards 3-1
 a. Describe the relationship between the number of feet and the number of yards
 That is to say:
 1Yarda = 3 feet
 b. Write an expression for the number of yards in f feet
 Let
 y = Yard
 f = feet
 We have the following expression for the conversion:
 y = (1/3) f
 c. Find the number of yards in 63 feet 
 For this case we must substitute in the expression found the value of f = 63.
 y = (1/3) f
 y = (1/3) (63)
 y = 21
 answer:
 1Yarda = 3 feet
 y = (1/3) f
 y = 21
