This is 10.5^2 10.5 is the base and 2 is the exponent. The area is 110.25 square inches.
X/90 = 200/100 is/of = %/100
so cross multiply 90 and 200 and x and 100
giving you 18000 = 100x
divide both sides by 100
180=x
a. 60(h)+40=
b 60(3)+40=
180+40=$220
c. 400=60(h)+40=
360=60(h) *divide 60 on each side*
6=h, 6 hours
To solve for x in terms of b, simply treat b as a number, and solve for x as usual: first of all, we expand the left hand side:

Subtract 10 from both sides:

Divide both sides by -2b:

This means that in particular, if we set
, we have

0.36 is less than the shaded portion of the grid. Brainliest, please?
