Answer:
need to work out how long it would take 1 person first.
9 X 5 = 45
1 person will take 45 hours
45/3= 15 hours
B=200 so place it next to the equation and then just solve for w
The value of a number is for example 7, 70 (but also 8, 80, etc). 7 can refer to the value of seven if it's on its own or if it's on the rightmost position, but in the number 75, seven refers to the value of 70. The same digit can have different values in a place value system where the value represented by a digit depends on its position.
Let the price before increase be Rs.100
Then , as the tpercentage increase =25%
Therefore, increase in price =
100
25
×100
=Rs.25
Therefore increased price =Rs.125
Therefore the percentage by which house wife should decrease the consumption be(
125
25
×100)%
=20%
Answer:
D. 22,417 feet
Step-by-step explanation:
Fine the diagram in the attachment for proper elucidation. Using the SOH, CAH, TOA trigonometry identity to solve for the distance (x) from the plane (P) to the observer (O), the longest side x is the hypotenuse and the side facing the angle of elevation is the opposite.
Hypotenuse = x and Opposite = 15,000feet
According to SOH;
Hence the distance (x) from the plane P to the observer O is approximately 22,417 feet
