A ship is traveling around the outside rim of an island surveying a good place to land. If it is 10 miles from a lighthouse at the center of the island and 45° from due north, how far has the ship traveled from the most northern tip of the island to the nearest tenth?

Answers

Answer 1

Answer: The correct answer for the question that is being presented above is this one: "C. 7.9 miles."

Area of the circle = pi * r^2
= pi * 100
= 314.15927.

It's traveled 45/360 = 1/8 of the circumference

Here are the following choices:
A. 0.8 miles
B. 4.5 miles
C. 7.9 miles
D. 12.5 miles

Answer 2

Answer:

Step-by-step explanation:

Read the answer above/ below mine, I just wanted to point out that to solve this problem you use the circumference formula! The circumference of a circle is 2pi(r). r= radius= 10 (because 10 mi). Plug this into a calculator by typing: (20*pi) [division symbol] 8 =, and then it will give you 7.85..., but remember to round up to 7.9.

Answer:

" $8\pi$ units squared"

Step-by-step explanation:

The image of the circle is attached.

The shaded area of the circle is basically HALF of the whole circle. If we can get the area of the circle, we will halve it, to get our answer for area of shaded region.

Area of circle is given as:

$A=\pi r^2$

Where

A is area

r is the radius

Looking at the pic, the radius is "4", so we substitute and find area of circle:

$A=\pi r^2\nA=\pi (4)^2\nA=\pi (16)\nA=16\pi$

THe shaded area is HALF of that, so:

Area of Shaded = $(16\pi)/(2)=8\pi$ sq. units.

Answer is " $8\pi$ units squared"

78 divided by 190

steps

Answers

78 x 100 = 7800

How many times does 190 go into 780?
≈ 4....190 x 4 = 760

780 - 760 = 20...bring down the extra 0 to make it 200.

How many times does 190 go into 200?
≈ 1...subtract 190 from 200 to get a remainder of 10

190 ÷ 7800 ≈ 41

Aaron removes 29 candies from a jar. There were originally 79 candies in the jar. How many candies are left in the jar?

Answers

There are 50 candies left in the jar.

What is mean by Subtraction?

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

There are 79 candies in the Jar.

Aaron remove 29 candies from the jar.

Now,

Total number of candies in the jar =n 79

And, Aaron remove 29 candies from the jar.

Thus, Left candies in the jar = 79 - 29

= 50

Therefore, There are 50 candies left in the jar.
