Answer:
Here are the formulae you need. Just plug in the values you have and you will get your answers.
Area of a triangle: 1/2*base*height
Volume of a rectangular prism: length*width*height
Volume of a cylinder: pi*r^2*height
Step-by-step explanation:
Answer:
4+62=66
Step-by-step explanation:
Since the triangles are similar, then 32 = x+7 those two angles are too
solve for "x"
now using proportions
![\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{JK}{18}=\cfrac{12}{12+10}](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B%5Ctextit%7Bsmall%20triangle%7D%7D%7B%5Ctextit%7Blarge%20triangle%7D%7D%5Cqquad%20%5Ccfrac%7BJK%7D%7B18%7D%3D%5Ccfrac%7B12%7D%7B12%2B10%7D)
solve for JK
![\bf \cfrac{\textit{small triangle}}{\textit{large triangle}}\qquad \cfrac{12}{12+10}=\cfrac{9}{9+KG}\implies 12(9+KG)=(22)9 \\\\\\ 108+9KG=198](https://tex.z-dn.net/?f=%5Cbf%20%5Ccfrac%7B%5Ctextit%7Bsmall%20triangle%7D%7D%7B%5Ctextit%7Blarge%20triangle%7D%7D%5Cqquad%20%5Ccfrac%7B12%7D%7B12%2B10%7D%3D%5Ccfrac%7B9%7D%7B9%2BKG%7D%5Cimplies%2012%289%2BKG%29%3D%2822%299%0A%5C%5C%5C%5C%5C%5C%0A108%2B9KG%3D198)
solve for KG
the scale factor of the perimeter of both triangles is just the same as the ratio of the sides, or
Answer:
x > 9
Step-by-step explanation:
Hello!
First let's solve the inequality for x.
<u>Flip the sign if you are dividing by a negative number.</u>
<h3>Solve for x</h3>
Now let's graph it on a number line. If it is a greater or less than symbol, we use an open circle. If it is a greater than or equal to or a less than or equal to, we use a closed circle.
Plot the point of 9 with an open circle, and shade in a line towards the right (all values greater than 9).
