Answer:
x = 9 1/3
Step-by-step explanation:
We can use the ratios of similar triangles to solve
x 7
----------- = ------------
x+8 13
Using cross products
13x = 7(x+8)
Distribute
13x = 7x+56
Subtract 7x from each side
13x-7x = 7x+56-7x
6x = 56
Divide each side by 6
6x/6 = 56/6
x= 28/3
x = 9 1/3
X² + 6x = 22
x² + 6x = 31 - 9
x² + 6x + 9 = 31
(x+3)² = 31
Answer:
Angle y is also 40 degrees. Angle x and y are vertical angles, thus they have the same angle measure.
Step-by-step explanation:
Answer: The larger cylinder would 90cm^3
Step-by-step explanation:
If both have a base area of 10cm^3
Try to work the problem normally and just add the cube as your unit. 6cm is your height for the small cylinder so add 3 meaning the large will be 9cm tall. Then multiply, 10cm by 9cm = 90cm^3.
The formal is V=pi r^2 h
Hopefully this helps.
Answer:
76/15
Step-by-step explanation:
Add the drug combinations together
Drug A + B + C=2/5 + 5/3 + 9/3
The L.C.M of the denominators is 15
=6+25+45/15
=76/15
Or
=5 1/15
