Answer:

If two vectors are parallel, applying the same side interior angles theorem:

=> 80 + a + 59 = 180

=> a = 180 - 80 - 59 = 41 deg

Hope this helps!

Or you could apply alternate angle theorem

Alternate angles make a "z" shape. Alternate angles are equal

So now that we know the third side of the triangle is equal to 59, we do 180=a+59+80

Move fifty nine and eighty to the other side as negative numbers

a=180-59-80

So, a is equal, to 41 :))

A jar can hold of a pound of flour. Austin empties of a pound of flour into the jar. What fraction of the jar is filled? Enter y
11111nata11111 [884]

Answer:

<em>2/3 of the jar was filled with flour</em>

Step-by-step explanation:

The question is incomplete. Here is the complete question.

<em>A jar can hold 3/4 of a pound of flour. Austin empties 1/2 of a pound of flour into the jar. What fraction of the jar is filled? Enter your answer in numerical form.</em>

<em />

Given

<em>Amount a jar can hold a = 3/4 of a pound of flour</em>

<em />

<em>If Austin empties 1/2 of a pound of flour into the jar, then the amount emptied into the jar b = 1/2 pounds</em>

<em />

<em>Fraction of jar filled will be expressed as b/a as shown;</em>

<em>b/a = (1/2)/(3/4)</em>

<em>b/a = 1/2 ÷ 3/4</em>

<em>b/a = 1/2 * 4/3</em>

<em>b/a = 4/6</em>

<em>Simplify to the lowest term</em>

<em>a/b = 2*2/2*3</em>

<em>a/b = 2/3</em>

<em />

<em>Hence 2/3 of the jar was filled with flour</em>

Find the volume of a cylinder that has a radius of 7 and a height of 18.
ch4aika [34]

Answer:

V = 882pi units^3

or approximately

2769.48 units^3

Step-by-step explanation:

The column of a cylinder is given by

V = pi * r^2 * h

We know the radius is 7 and the height is 18

V = pi * 7^2 *18

V =pi *49 *18

V =882 pi

If we want an approximate answer, we can approximate pi by 3.14

V = 3.14 * 882

V =2769.48
