Answer:
x=-b/2a
Step-by-step explanation:
hope that helps :)
mark as brainliest please :)
The chef will be able to prepare 3 servings of pasta because if you take one away from a whole number you have 9/10ths so you do that process again you have 2 servings but, you have 2 tenths left over so you add that to the 7 tenths.
Hope this helps :)
Step-by-step explanation:
The die is rigged, so "not 3" is not a possibility. Ruling out those branches of the tree, there are 4 possible outcomes, one of which is the desired outcome. So the probability is 1/4.
A fair die has six sides that are equally likely, so the probability of rolling more than 2 is always 4/6. The outcome of the first roll does not effect the outcome of the second roll.
We see that the shape is made up of 2 shapes:
trapezoid and triangle
(trapezoid is on top of upside down triangle)
area of trapezoid=(1/2)(b1+b2)(h)
area of traignel=(1/2)(b)(h)
area of trapezoid
b1=14
b2=18
h= ok so total height=17 and 12 is taken up by triangle os therefor h=17-12=5
A=(1/2)(14+18)(5)
A=(1/2)(32)(5)
A=(16)(5)
A=(80)
now area of triangle
H=12
B=18
A=(1/2)(18)(12)
A=(9)(12)
A=108
add
80+108=188
total area=188mm^2
Surface area of a cylinder = 2πrh+2πrsquared
= 2x3.14x4.5x12+2x3.14x20.25
= 339.12+127.17
= 466.29
Therefore, the surface area of a cylinder is 466.29cm
