Answer:
The whole brownie is 3/3
Step-by-step explanation:
Hello!
This is a classic fractions exercise.
The whole brownie was cut in three equal pieces. Each piece represents 1/3 of the brownie.
If you add the three pieces together 1/3+1/3+1/3 you get the whole brownie again 3/3 = 1
-Options-
The whole brownie is 1/3.
<em>The whole brownie is 3/3. </em>
The whole brownie is 2/3.
The whole brownie is 3/2.
I hope this helps!
We have
SinC/ c = Sin A / a
Sin 71/ 26 = Sin A / 27
Sin A = 27 Sin 71 / 26 = about .982
So°
Sin-1(.982) = A = 79. 08°
Then angle B = 180 - 71 - 79.08 = 29.92°
And b is given by
b/sin29.92 = 26/sin 71
b = 26sin29.92/sin71 = about 13.72
But A could also be an obtuse angle = 180 - 79.08 = 100.92°
So we have
B = 180 - 71 - 100.92 = 8.08°
And we have
b / sin 8.08 = 26/sin71
b = 26sin8.08/sin 71 = 3.865

1/4+3/7
7/7.4+3.4/7.4
7/28+12/28
19/28
Step-by-step explanation:
4(2)² - 4 =
4(4) - 4 = 12
3(2)² - 3(4)
3(4) - 12
12 - 12 = 0.
It exceeds the value by 12 :)
