Rectangle (left): A = 9 x 7 = 63

Rectangle (right): A = 2 x 10 = 20

Quarter circle: A = (1/4 x 3.14 x 3^2) = 7.065

A = 63 + 20 + 70.65

A = 90.065 square feet

Hope this helps! :)

Which problem can be solved by expression 3/8 divided 1/4?

NeTakaya

Answer:

3/8÷1/4=1 1/2

Step-by-step explanation:

I am not sure what you are asking here, So I am gonna explain how you divide this.

So using the KCF method (Keep Change Flip) You would KEEP the first fraction (3/8) and CHANGE the operation (from divide to multiply) then FLIP your second fraction (1/4 to 4/1)

After doing this, it should look like:

3 4

8 1

Now that we got that, you multiply from left to right. 3×4 is 12. 8×1=8.

That should leave you with 12/8. But this is an improper fraction. So you would divide top by bottom to get a mixed fraction.

It should look like this

01. 1 1/2

8 12

Step by step explanation:

8 only goes into 12 one time. So you would subtract 12 by 8, and get 4. From that you would get 1 4/8 but 1 4/8 can be simplified to 1 1/2.

So it is 1 1/2

Answer:

$\large\boxed{\theta=-\dfrac{\pi}{4}+k\pi\ or\ \theta=k\pi}\ for\ k\in\mathbb{Z}$

Step-by-step explanation:

$\tan^2\theta+\tan\theta=0\\\\\tan\theta(\tan\theta+1)=0\iff\tan\theta=0\ \vee\ \tan\theta+1=0\\\\\tan\theta=0\Rightarrow \theta=k\pi\ \text{for}\ k\in\mathbb{Z}\\\\\tan\theta+1=0\qquad\text{subtract 1 from both sides}\\\\\tan\theta=-1\Rightarrow\theta=-\dfrac{\pi}{4}+k\pi\ \text{for}\ k\in\mathbb{Z}$

What is the remainder in the division problem

Cerrena [4.2K]

I believe the answer is 2, the 3 large circles are filled with 5 dots each, the total number of dots is 17. 15 is the number closest to 17 that can be divided by 3 therefore there would be 2 left over (the 2 dots on the outside)
