220ft squared

To find the area, you find the area of the 3 main figures, the triangle on the right, the square on the top left, and the rectangle left on the bottom and add all the areas up. If you do not know how to do this, please comment and I will guide you. :)

Answer:

3/8

Step-by-step explanation:

Rearrange, find common denominator.

$x = \frac{7}{8} - \frac{1}{2} \\ x = \frac{7}{8} - \frac{4}{8} \\ x = \frac{3}{8}$

a circle is divided into 18 equal parts how many degrees is the angle for each part? how many degrees is the angle for 5 parts?

Ket [755]

There are 360 degrees in a circle, and we have 18 pieces, so we need to see how many times 18 goes into 360. We can find this out by dividing.

360/18=20

You can check this by multiplying 20 and 18 (it equals 360)!

So, each fraction of the circle will be 20 degrees.

If you take 5 of these 20 degree pieces, you'll need to multiply them by 20 to see how many degrees they'd be.

You need to multiply by 20 because each piece is 20 degrees, and we need to find how many degrees 5 pieces is. It's the same as doing
20+20+20+20+20! :)

20*5=100. 5 parts will be 100 degrees.

Hope I helped! :)

Graph the six terms of a finite series where a1 = −3 and r = 1.5.

s344n2d4d5 [400]

We are given the first term and the common ratio, this means they belong to a geometric series.

For the given series:

$a_{1}=-3 \\ 
r=1.5$

Each term of the geometric series is obtained by multiplying the previous term by common ratio.

So the next terms will be:

-4.5, -6.75, -10.125, -15.1875, -22.78125

The general formula for the G.P would be:

$a_{n}=-3(1.5)^{n-1}$

On plotting the series, the result will be like this:
