Answers

Answer 1
Answer:

Answer:

60 words

Step-by-step explanation:

20*/X3=60
Answer 2
Answer:

Answer:

60 words

1/3 of an hour is 20 minutes

20 words every 20 minutes is 1 word per minute, 60 minutes is 60 words.

OR

20 = 1/3 (hour)

x3

60= 1 (hour)

What is 75%,1/6,3/8,and 0.625 from least to greatest

Answers

Convert each term in decimal form. This is avoid confusion and for uniformity and ease in comparing the value of each term.

75%   is   0.750
1/6     is   0.167
3/8     is   0.375
0.625 is   0.625

From least to greatest, the order is: 

0.167 , 0.375 , 0.625 , 0.750 

Is this equation standard form of an ellipse or circle?-3x^2-3y^2-12x-12y+24=0
What's the center?

Answers

The standard form equation for a circle is

(h-x)^2+(k-y)^2=r^2

where (h, k) is the center and r is the radius.

The standard form equation for an ellipse is

((x-h)^2)/(a^2)} + ((y-k)^2)/(b^2) = 1

(center h, k and major and minor axes a and b)

This equation is standard form for neither, but might be general form for one.

1.75 = 12.3 - x / 2.8

Solve for x

Answers

1.75=12.3-x/2.8
x=(12.3-1.75)2.8
x=29.54
1.75 = 12.3 - x / 2.81.75-12.3=-x/2.8

-10.55=-x/2.8

-10,55*-2.8=x

x=29.54

The perimeter of an equilateral triangle is 12\/3 cm. Find the radius, apothem and area of the equilateral triangle.

Answers

Answer:

Radius -  4

Apothem -  2

Area - 12√(3) or 20.8

Step-by-step explanation:

Try to draw out my explanation so you know what this looks like.

~~~~

This is an equilateral triangle, so all sides are the same length. The perimeter can be divided by 3 to get each side length...

12√(3) /3 = 4√(3)

Now that we know the side lengths, we can get this started!

~~~~

Now, an equilateral triangle has angles that all equal 60 degrees. We can bisect this into TWO special case triangles of measures 90-60-30.

4 times the square root of 3 will be the hypotenuse, and the smallest leg is always half of that. The larger leg is represented as the small leg times the square root of 3.

Small=2√(3) \nHypotenuse = 4√(3) \nLong =6

By the way, the formula for the area can be either of the two:

A= (1)/(2) bh\nor\nA = (1)/(2) NAS

we can easily find the area using the first formula.

A= (1)/(2) (4√(3) )(6)\nA=12√(3)

The radius is the distance from the center to the corners & the apothem is the distance from the center to a side...

So we can divide the big triangle into a mini triangle at the bottom left/right

The height (small leg) of that triangle would be the apothem

The hypotenuse of that triangle would be the radius.

I did the math really quick because this is getting long. Anyhow, the small leg is 2 so is the apothem, and the hypotenus is 4, so is the radius

Happy April Fool's btw, lol.
