Answer:
x2+x-4=0
Step-by-step explanation:
<span>17 1/3 + (-50 1/3) -5 1/2
= -33 - 5 1/2
= (</span>-33 ) + ( - 5 1/2)
<span>= -38 1/2

Answer:
8587 should be in the box
Step-by-step explanation:
we would see it question as: 12/- 8587
12 goes into 85 7 times, so 7
12 goes into 18 1 time, so 1
12 goes into 67 5 times, so 5
then the remainder is 7
or you further divide to get . 5 8 3333333...
so your answer should be 715r7 or 715.58333
Answer:
A = 23.6 units^2
Step-by-step explanation:
Let the base be 8 (as shown).
Find the height of the triangle: Find the supplement of the 100 degree angle; it is (180 - 100), or 80 degrees. The side "opposite" this 80-degree angle is the height of the triangle:
height
sin 80 degrees = ---------------
6
and so the height of the triangle is h = 6 sin 80 degrees, or 5.91 units.
The area of the triangle is found using A = (1/2)(base)(height), which here amounts to:
A = (1/2)(8 units)(5.91 units), or
A = 23.64 units^2, or A = 23.6 units^2
