Answer:
39 sq cm
Step-by-step explanation:
Ok. Since ΔAED is isosceles, then the height of the trapezoid is 3 cm
One base is 16 and the other base is 16 - 3 - 3 = 10.
A = 1/2 h( + ) where and are lengths of the bases
A = 1/2(3)(10 + 16)
= 1/2(3)(26)
= 39 sq cm
One of the zeroes would be : x = 1
f (1) = 1^3 + 6(1) ^2 + 3 (1) - 10
f(1) = 1 + 6 + 3 - 10
f (1) = 10 - 10
f (1) = 0
Hope this helps
The formula for the surface area of a triangle pyramid is shown below:
SA = A + (3/2)Bh
Where SA for surface area, A=base are, b=base and h=height.
We can solve for surface are since all values needed are given.
SA = (0.07) + (3/2)*1.2*0.75
SA=1.42 square foot
Therefore, the surface area is 1.42 square foot.
Answer:
23/30 are blue balloons. 23/30 = 76.7 = 0.767. I would say that 0.767 is the answer!
