P= 48
6+6= 12
48-12= 36
36/2= 18
Answer: Length= 18 inches
Answer:
Step-by-step explanation:
(x + 22)/2 = 27
x + 22 = 54
x = 32
(y + 16)/2= 9
y + 16 = 18
y = 2
(32, 2)
Answer:
100 inches
Step-by-step explanation:
Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .
<u>Using</u><u> </u><u>this </u><u>concept</u><u> </u><u>,</u><u> </u>
=> AM / PN = QA / QP
=> 108 / 71 = 52 + x / x
=> 1.52 x = 52 + x
=> 1.52 x - x = 52
=> 0.52 x = 52
=> x = 52/0.52
=> x = 100 in .
Answer:
40 days
Step-by-step explanation:
20 men = 30 boys can do the job so
10 men = 15 boys
30 boy hours = 36 days
30 * 36 = 1080 boy days
We have 10 men and 12 boys to do the job
We replace the 10 men with 15 boys
We have 15 boys and 12 boys for a total of 27 boys to do 1080 boy days worth of work
27 * day = 1080 boy days
days = 1080 /27
days = 40
