Answer:
d. 42 degrees
Step-by-step explanation:
y and 92 are supplemetary angles, which means they both add up to 180 since they are on the straight line.
Hence,
y+92 = 180
y = 180-92
y=88
And now we also know that all the angles of a traingle add up to 180,
so, we can simply find the x by:
88+x+50 =180
138 + x =180
x = 180-138
x = 42

The negative of it would be the positive so the answer is 1/4
Answer:
850 leaves were on the tree initially.
Same as;
2/5 + 1/5 + 3/10 + (remaining leaves 1/10) = 1
4/10 + 2/10 + 3/10 + 1/10
10 x 85 = 850
Step-by-step explanation:
2/5 wk 1 fall off
1/5 wk 2 fell off
3/5 x 1/2 = 3/10 wk 2 stayed on tree
1/3 x 3/10 = 1/10 wk 3 stayed on
2/5 + 1/5 + 3/10 = 9/10 = 0.9 fall off in total
10/10 - 9/10 = 1/10 left on tree
1/10 = 85
10 x 85 = 850 leaves.
If you only used 13% then you used 4.42 pounds of dry ice.
