How To Solve This Problem By Finding X

Answers

Answer 1

Answer:

X=140

Step-by-step explanation:

Firstly, any Quadrilateral has a total sum of its angle equal to 360 degrees

The attachment you are showing us shows that we already know two angles

(70)&(60) degrees. I am assuming the line DC is a tangent, so angle ADC must be 90 degrees since a full angle on a tangent is equal to 180 degrees and there is 90 from the other side (180-90=90). Now we know 3 angles and what you have to do is find X so that when you add them all up they make a sum of 360.

X+70+60+90=360

X=360-70-60-90

X=140

The heights of basketball players (cm) in one NBA team are given as follows. {158, 180, 185, 192, 192, 195, 196, 198, 200, 205, 213}. The data can be represented in the box-and whisker plot below (picture).
(a) Find the values of a, b , c, d, and e.
(b) Calculate d-b. What does it represent?
(b) Calculate e-a. What does it represent?

Answers

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.

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

According to the credit calendar below, what is the average daily balance?

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.

What is a linear equation?

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

A road construction company can repair 1/4 mile of road each day. Road X is 7 ½ miles long, and Road Y is 5 ¾ miles long. How many more days will Road X take to repair than Road Y? Answer value

Answers

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

Two helicopters leave a heliport at the same time. The first flies 160km/h in a direction of 290 degrees. The second flies 100km/h in a direction of 250 degrees. After 3 hours, how far apart are the helicopters? Round your answer to the nearest kilometer.

Answers

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
