Answer:
y = 1/2x+2
Step-by-step explanation:
4x+6y=12 solve for y please
Answers
Answer:
y=2-(2/3)x
Step-by-step explanation:
4x+6y=12
subtract 4x from both sides
4x-4x+6y=12-4x
0+6y=12-4x
divide the equation by 6
6y/6=(12-4x)/6
y=12/6-4x/6
y=2-(2/3)x

So what you should do is add the angles that are given to you and then subtract it from 180
Working:
100 + 20 + x = 180
120 + x = 180
x = 180 - 120
x = 60 degrees
I hope this helps you and your welcome

Please help :(
Answers
Answer:
1357.2
Step-by-step explanation:
volume = r^2 * pi * h
= 6^2 * pi * 12
=432pi
The volume of cylinder is 1357.17 cubic centimeter.
Formula to find the volume of cylinder:V = base area × height
[tex]V=\pi \times r^{2} \times h[/tex], where r is the radius of circular base and h is the height of the cylinder.
For given example:
a base radius (r) = 6 cm,
a height of a cylinder (h) = 12 cm
Using the formula of volume of a cylinder,
[tex]V=\pi \times 6^{2} \times 12[/tex]
[tex]V=1357.17[/tex] cubic cm
Hence, the volume of a cylinder is 1357.17 cubic centimeter.

Mr. Crosgrove tipped $3.84.
120 pens are not red pens.
She had to pay $270 in taxes.
Step-by-step explanation:
So, to find the percentage of something you convert the percentage to a decimal and then multiply.
For #1
He spent $48, and tipped 8%
to turn 8% into a decimal you bring in down two place values, so it is 0.08. You multiply 48 * 0.08 and you get 3.84.
Mr. Crosgrove tipped $3.84.
For #2
He has 150 flair pens and 20% are red. Multiply 150 by 0.2. You will get 30. Now we know that there is 30 red pens, but the problem is asking how much is not red pens. subtract 150-30 and you get 120, so that is the answer.
120 pens are not red pens.
For #3
She has $2,000 and had to pay 13.5% You have to turn 13.5% into decimal so bring place value down by two so it is now 0.135. Multiply 2,000*0.135 and you get 270.
She had to pay $270 in taxes.
Hope this helps!!

Alright so assuming the this is a right angle, to find the area of a triangle you have to multiply LxW and divide by 2. 3x4=12/2=6. There are 2 triangles, so 6x2=12
And then to find the area of the rectangle on the bottom, 10x4=40
Next you find the area of the rectangle on the side: 3x10=30
And finally the one that’s slanted on the top: 5x10=50
Add them up and 12+40+30+50= 132
