Answer:
Step-by-step explanation:
a) Area of white square = side *side = 8 * 8 = 64 sq.mm
Area of 4 white square = 4 * 64 = 256 sq.mm
compound shape
length = 3 cm = 30 mm
Width = 2 cm = 20 mm
Area of compound shape = length *width = 30 * 20 = 600 sq.mm
Area of the shaded part of the compound shape =
Area of compound shape - Area of 4 white square
= 600 - 256
= 344 sq.mm
b) Perimeter of compound shape = 2*(length + width)
= 2*(30 +20)
= 2* 50
= 100 mm
.6 because it is very low compared to the other numbers
5x=25 could be one.
25/x-3=2 is another.
And the last one could be x/85+7=24
Answer:4800'
Step-by-step explanation:
It is 4800' because x = the number of seconds between the lightning and thunder and 1,200 is in feet. so, if there is four seconds between the time of the lightning and thunder then you can use the equation given f(x) or 1,200(x) to solve it. to do this you supplement the x with 4 which gives you 1,200(4) or the same as 1,200 · 4 = 4800ft.
