Find the circumference of a circle with a radius of 35 inches in terms of 7 and to the nearest tenth of an inch.

Lera25 [3.4K]

Answer and Step-by-step explanation:

The circumference formula for a circle is:

C = $2\pi r$

Plug 35 in for r (radius) and solve.

C = $(35) 2\pi\\\\C = 70\pi\\\\C = 219.9$

So, approximately 219.9 $in^2$ is the answer.

A group of students are meeting in the cafeteria. 70 students have already arrived. This is 35% of the group. How many are in th

sesenic [268]

There are 200 students in the group.

To find this, you divide 70 by 0.35 (35%). This will give you 200. To check this, multiply 200 by 0.35 and you will get 70. Thus making 200 the answer.

I hope this helps!

The angle of elevation of the top of a tower from a point 100m away is 45 degrees. What is the height of the tower to the neares

OLEGan [10]

<h3>Answer: 100 meters</h3>

===========================================

Explanation:

If you draw out the diagram, then you'll find that a 45-45-90 triangle forms. The nice thing about this type of triangle is that the two legs are always the same length. The horizontal leg is 100 meters, so the vertical leg must also be 100 meters.

Side note: this type of triangle is an isosceles right triangle.

---------

You could use the tangent rule to get the same thing

tan(angle) = opposite/adjacent

tan(45) = 100/x

1 = 100/x

1*x = 100

x = 100

In this case, the opposite leg is the vertical leg since it is furthest from the angle of elevation.

SSSSS [86.1K]

Answer and Step-by-step explanation:

In the equation y = 25x + 100, the format of y = mx + b is being used. This is a very commonly used base for equations in math, especially when it comes to graphing.

In the equation, the m stands for the slope in the equation, and the b stands for the y intercept. Slope can also be found by taking the rise/run of a graph.

So, the slope of this line is 25, and the y-intercept 100.

I have also included the this equation on a graph as well.

I hope that this helps.
