Answer:
1/3 is 33% and 1/12 is 0.83%
Step-by-step explanation:
Answer:
y=6nx-10
y+10=6nx
y+10/6x=n
therefore, n=y+10/6x.
Step-by-step explanation:
72 % of 300 is 216
Divide 216 ( # of boxes unloaded ) by 30 (minutes they were unloading)
216 / 30 = 7.2
They unloaded 7.2 boxes each minute.
**DOUBLE CHECK:
Multiply 7.2 by 30
7.2*30 = 216
Answer : 7.2 boxes/minute
Answer:
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
Step-by-step explanation:
The two angles above the horizontal line form a linear pair, so they are supplementary. Their measures add to 180 deg. That let's you find the value of x.
28x - 7 + 24x + 18 = 180
52x + 11 = 180
52x = 169
x = 169/52
x = 3.25
Now use the lower left angle and the upper right angle. They are vertical angles, so they are congruent. That allows you to solve for y.
12y + 30 = 24x + 18
We know that x = 3.25.
12y + 30 = 24(3.25) + 18
12y + 30 = 78 + 18
12y = 66
y = 66/12
y = 5.5
I don't know what the problem is asking for since you don't show.
x = 3.25; y = 5.5; angle measures are (cw from bottom left): 96, 84, 96
