Answer:
$420
Step-by-step explanation:
130x12=1560
165x12=1980
1980-1560=420
Well, 9/10 is the same as 9 10ths, the decimal that represents that is 0.9 because it is also 9 10ths
Answer:
x = 8 units
Step-by-step explanation:
Note that the ratio of the middle-length legs is 12/18, and that of the shortest-length legs is x/12.
Then:
12 x
----- = -----
18 12
... which, through cross- multiplication, becomes 18x = 144. Then x = 8 units
Angle ADC and EDG are congruent(vertical angles)
Same side interior angles are =180
2x+4x-30=180
6x-30=180
6x=210
x=35
CDG is congruent to DGH(alternate interior)
4x-30
4(35)-30
140-30
=110
Answer: 10%
Step-by-step explanation:
Since the shopkeeper purchased 60 pencil boxes for 4,500, he purchased them at the rate of:
= 4500 / 60
= 85 per pencil box
If the shopkeeper sold them at the rate of 4,125 for 50 pencil boxes, then he sold them at the rate of:
= 4125 / 50
= 82.50 per pencil box.
Therefore the percentage profit will be:
= Gain / Cost price × 100
= (82.50 - 75) / 75 × 100
= 7.5/75 × 100
= 10%
