Step-by-step explanation:

this is an improper fraction to make it mixed you have to find how many 20s are in 23

yea only one

so 1 is the whole number

then it is 1 3/20

you can again make it improper by multiplying denominator by 1 and adding 3

Answer:

$1\frac{3}{20}$

Step-by-step explanation:

'23' fits into '20' one time. So, '1' would be the whole number. We would be left over with ' $\frac{3}{20}$ ' as the remainder, so ' $\frac{3}{20}$ ' would be the fraction of the mixed number.

Put them together, and you get: $1\frac{3}{20}$

The fraction is already in it's simplest form.

Estimate the original volume of the pyramid in Fig. 15.28, given that its frustum has a 4 m by 4 m square top which is 12 m vert

puteri [66]

The volume of the pyramid is 2496 cu.m.

<h3>What is a Pyramid ?</h3>

A pyramid is a three dimensional structure which has a polygon base and in general triangular faces which join at the top .

It is given that

A pyramid $\rm frustum$ has a 4 m by 4 m square top

Height = 12 m

Base = 20 m

The volume of a square pyramid with a $\rm frustum$ is given by

V = (1/2) * ( Area of base + Area of $\rm frustum$ ) * height of the $\rm frustum$ from the base

V = 0.5 * ( 20 *20 + 4*4 ) * 12

V = 2496 cu.m

The volume of the pyramid is 2496 cu.m.

What is the simplified form of the following expression? 2√27+√12-3√3-2√12

LiRa [457]

Answer:

√3

Step-by-step explanation:

The given expression to be simplified is

$2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12}$

but

$2 \sqrt{27}=2\sqrt{9 \times 3}=2 \times \sqrt{9}\times \sqrt{3}=2 \times 3 \times\sqrt{3}=6 \sqrt{3}$

$\sqrt{12}=\sqrt{4\times3}= \sqrt{4}\times \sqrt{3}=2\sqrt{3}$

Since √12=2√3,this implies that,

$2\sqrt{12}=2\times2\sqrt{3}=4 \sqrt{3}$

Therefore,

$2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12}=6\sqrt{3}+2\sqrt{3}-3 \sqrt{3} -4\sqrt{3}$

$=(6+2-3-4)\sqrt{3}$

$=\sqrt{3}$

The simplified form of ,

$2 \sqrt{27}+\sqrt{12}-3\sqrt{3}-2 \sqrt{12}$ is √3

Can anyone answer this for me?

kramer

Answer:

$\frac{3}{2}$ π (or 270°)

Step-by-step explanation:

I use the trick with the coordinates.

(0, -1)

cos270° = 0 (the x-coordinate)

sin270° = -1 (the y-coordinate)

This trick works depending on the radius.
