Ответ:
6t=100(4.5h)
t=100(4.5h)/6
t=75
It takes a total of seventy-five hours to restore the boat.
Ответ:
You can find this by multiplying 100 by 6% to find the amount of times you need to do the same amount of work you've already done to complete the project.
This leaves you with 6, which you can multiply with 4.5 to get 27 hours.
Ответ:
answer: length of line segment bc = 6cm.
step-by-step explanation:
by the given problem a circle is inscribed inside a square abcd.
perimeter of a square = 24 cm =4×sides.
to find sides of square s= 24/ 4 = 6 cm.
∴the side of a square= 6 cm= length of bc as it is a side of square.
which is equals to the diameter of the circle inside the square.
radius of circle=1/2 of diameter=6/2 = 3 cm.
now by the figure diagonal of square =d
is given by pythagoras theorem
∴area of the square =![side^2= 6² = 36 cm^2](/tex.php?f=side^2= 6² = 36 cm^2)
area of the circle=
area of the spaces between the circle and square = 36 - 28.26 = 7.74 square cm
