Answer:

wind speed =  25  miles/hr

Step-by-step explanation:

let a = speed of the wind

speed with the wind = 255 + a , since the wind is not against him

speed against the wind = 255 - a

travel time is same for against and withe wind

therefore,

speed = distance/time

time = distance/time

448/255 + a = 368/255 - a

cross multiply

448(255 - a) = 368(255 + a)

114240 - 448a = 93840  + 368a

114240 - 93840 = 448a + 368a

20400  = 816a

divide both sides by 816

a = 20400/816

a = 25  miles/hr

Is AB parallel to Bo? Explain.
Svetradugi [14.3K]

Answer:

AB parallel to CD because both lines have a slope of

of 4/3

Step-by-step explanation:

The question is not complete, there is no graph.

A graph for the question is attached below.

From the image attached below, line 1 passes through points A = (-3, -3) and point B = (0, 1) while line 2 passes through point C = (0, -5) and point D = (3, -1).

Two parallel are said to be parallel if the have the same slope. The slope of a line passing through points:

(x_1,y_1)\ asnd\ (x_2,y_2).\ The\ slope \ is\ given\ as:\\\\Slope(m)=\frac{y_2-y_1}{x_2-x_1}

Line 1 passes through points A = (-3, -3) and point B = (0, 1), the slope of line 1 is:

Slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{1-(-3)}{0-(-3)}=\frac{1+3}{0+3}=\frac{4}{3}

Line 2 passes through point C = (0, -5) and point D = (3, -1). the slope of line 2 is:

Slope(m)=\frac{y_2-y_1}{x_2-x_1}=\frac{-1-(-5)}{3-0}=\frac{-1+5}{3}=\frac{4}{3}

Therefore AB parallel to CD because both lines have a slope of

of 4/3

John deposited $2860 in a bank that pays 9% interest, compounded monthly. Find the amount he will have at the end of 3 years.
Verdich [7]
All you got to do first is:

Change the 9% to decimal, which is .9
and then multiply all numbers
 
$2860 x .9 x3 is $7,722

Hope this helps! (Hope im right)

Polygon ABCD is plotted on a coordinate plane.If the polygon translates 3 units to the left and 1 unit down,the length of diagon
Hatshy [7]
The length of the diagonal will be 2.

When a translation is performed on a shaped, it simply moves location. The size and shape of the object do not change. Therefore, the length of AC will remain the same at all times.

Your neighbor has a square shaped pool with side lengths of 3a5 what is the area of the pool
Anvisha [2.4K]

If a square-shaped pool with side lengths are 3a^5 then find the area of the pool

solution:

A = (3a^5) x (3a^5)

   = 9a^5+5

   = 9a^10

The area of the square-shaped pool are 9a^10 based on the given side length which is 3a^5
