Find the specific measure below.

Answer: 315 km

Step-by-step explanation:

If the angle θ is measured from the x-axis, and we have a magnitude A, we can find the rectangular coordinates as:

Ax = A*cos(θ)

Ay = A*sin(θ)

Then:

The first helicopter has a speed of 160km/h, and it's angle is 290°.

Then the components will be:

Vx = 160km/h*cos(290°) = 54.7 km/h

Vy = 160km/h*sin(290°) = -150.4 km/h

Then the point location as a function of time, can be written as:

(where i assumed that the initial position of both helicopters was (0, 0))

P1(t) = (54.7 km/h*t, -150.4 km/h*t)

where t is time in hours.

We can do the same for the other helicopter:

The speed is 100km/h, and the angle is 250°

Then:

Vx = 100km/h*cos(250°) = -34.2 km/h

Vy = 100km/h*sin(250°) = -94 km/h

Then the point location as a function of time, will be:

P2(t) = (-34.2km/h*t, -94 km/h*t)

After 3 hours, the position of each helicopter will be:

P1(3h) = (54.7 km/h*3h, -150.4 km/h*3h) = (163.1 km, -451.2 km)

P2(3h) = (-34.2km/h*3h, -94 km/h*3h) = (-102.6km, -282km)

Now we can calculate the distance between these two points.

Remember that the distance between the points (a, b) and (c, d) is:

D = √( ( a - c)^2 + (b - d)^2)

In this case the distance will be:

D = √(  (163.1 km - (-102.6km))^2 + (-451.2 km - (-282km))^2)

D = √(  (163.1 km + 102.6km)^2 + (-451.2 km + 282km)^2)

D = 315km

Answer:

Below in bold.

Step-by-step explanation:

(a)    a = 158.

The median = the middle value = c = 195.

The lower quartile = the middle value of the first 5 heights = 185 = b.

The upper quartile = the middle value of the last  5 heights = 200 = d.

(b)  d - b = 200 - 185 = 15 = the interquartile range (IQR).

(c)  e - a  is the range = 213 - 158 =  55.

Answer: 22,040/30= 734.666666667

Step-by-step explanation:

As per linear equation, the average daily balance on the given credit calendar is $716.17.

A linear equation is an equation where the highest degree of the variable is one.

Given, the daily balances for the given 30 days are $640, $640, $640, $640, $640, $640, $640, $640, $765, $765, $765, $765, $765, $820, $820, $820, $720, $720, $720, $720, $720, $720, $720, $720, $720, $720, $720, $720, $720, $720.

Therefore, the total balance in the given 30 days period is = [$640 × 8 +  $765 × 5 + $820 × 3 +  $720 × 14] = $21485.

Now, the average daily balance = $[tex]\frac{21485}{30}[/tex] = $716.17

Answer:

  c) 1.8 miles

Step-by-step explanation:

Assuming Kayla walks at a constant speed, we have ...

  miles/minutes = 3.2/45 = x/25

  x = 25(3.2/45) = 1.777... ≈ 1.8 . . . . miles

Kayla walks about 1.8 miles in 25 minutes.

Answer: 7 days

Step-by-step explanation:

From the question, we are informed that a road construction company can repair 1/4 mile of road each day. We are further told that Road X is 7 ½ miles long. The number of days that it'll take to repair road X will be:

= 7 1/2 ÷ 1/4

= 15/2 × 4/1

= 30 days

Road Y is 5 ¾ miles long. The number of days that it'll take to repair road Y will be:

= 5 3/4 ÷ 1/4

= 23/4 × 4/1

= 23 days

The difference in the number of days that Road X take to repair than Road Y will be:

= 30 days - 23 days

= 7 days

Step-by-step explanation:

okay, first imma simplify the question a little bit.

122 students; 46 chose football; 18 chose tennis; 28girls + xboys chose running.

okay now let's find the number of students who chose running

122 - 46 - 18 = 58

now, I'll find the probability

P(Running) = 58/122 = 29/61
