An airplane has an airspeed of 500 kilometers per hour (k/hr) in a
northerly direction (N 0˚ E). The wind velocity is 60 k/hr in a southeasterly (S45˚E)
direction. Let Va be the velocity of the plane relative to the air and Vw be the velocity
of the wind (both in terms of i and j).


1. Find vg = va + vw, the path of the plane relative to the ground. Round coefficients to the nearest tenth.

2. Find the actual speed and direction of the airplane relative to the ground. Round to the nearest tenth.

Susan rolled a die 1,086 times. Which of the following would be a good estimate of the number of times she rolled the number 3 on die?

Answers

Hello!

This is a problem about probability.

What we would first do is find the theoretical probability that Susan would roll the number 3 on a die.

Assuming that this is a fair six sided die, there is only one face with the number 3, and there are 6 sides, meaning that the probability that Susan rolls a 3 would be [tex]\frac{1}{6}[/tex].

Now, Susan is rolling a die 1,086, meaning that we can divide this number by 6 to find the theoretical number of times that Susan would roll the number 3 on this die.

You should get 181 times, which would be a good estimate of how many times she could roll the number 3.

Hope this helps!

Step-by-step explanation:

Volume of cuboid is length* breadth" height

Volume of cuboid is length* breadth" height=10*8*6= 480cm³

volume of traingular prism= this I don't know

okay wait...imagine there is other half of the traingle such that it becomes cuboid...now find area of cuboid = 5*5*4= 100

now divide by 2 to get half volume ( one triangular prism)

which is 100/2= 50

Volume of traingular prism= 50cm³

Total volume of figure= 480+50= 530cm³

A carpenter lays 18 square feet of tile in 2/3 of an hour. How many square feet of tile does the carpenter lay per hour?

Answers

Answer:

x=24

Step-by-step explanation:

there are different ways to solve the problem

set up a proportion:

16/(2/3)=x/1

cross multiply

(2/3)x=16

(3/2)(2/3)x=(3/2)(16)

x=24 square feet per hour

a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)

this means he lays 4 square feet every 10 minutes

8 square feet in 20 minutes

12 square feet in 30 minutes

24 square feet in 60 minutes

Find the measure of the angle indicated (x). Round to the nearest tenth. Show your work to support your answer.

Answers

Answer:

solution:

relation between perpendicular and base is given by tan angle

so

[tex] \tan(ø) [/tex]=perpendicular/base=4/13

ø=tan-¹ (4/13)=17.10°

angle indicated =ø=17.10°

tanØ=Perpendicular/BasetanØ=4/13Ø=tan^{-1}(4/13)Ø=17.1°

A child is flying a kite. If the string is pulled tight to its full length of 40 feet and is held at an angle of 71 degrees above the ground, how high is the kite? Round your answer to the nearest whole foot.

Answers

Answer:

38feet high

Step-by-step explanation:

Given the following

Length of the string = 40feet (hypotenuse)

Angle of elevation = 71 degrees

Required

Height of the kite (opposite)

Using the SOH CAH TOA identity

Sin theta = opp/hyp

Sin 71 = H/40

H = 40sin 71

H = 40(0.9455)

H = 37.82

Hence the kite is 38feet high (to the nearest whole number)

PLS HELP NO LINKS. Assume that RQ and RS tangent to circle T. solve for x.

Answers

Answer:

x = 6

Step-by-step explanation:

Here, we want to solve for the value of x

mathematically, tangents drawn from the same point to touch two points on a circle, are the same distance from the external point

thus;

QR = RS

Thus;

3x + 8 = 26

3x = 26-8

3x = 18

x = 18/3

x = 6
