Instead of using the ratio 2:3, use the ratio 2:5. This is useful because it
tells us the ratio of grasshoppers with white markings to all
grasshoppers. To find out how many grasshoppers have white
markings on their backs, you can create a proportion: 2 out of 5
equals x out of 290. By cross-multiplying:
2/5 = x/290
2(290) = 5x
580 = 5x
116 = x
About 116 of the photographs will show white markings.
Half of 32,404 is 16,202. So, the population of Baker is at least
16,202."At least" uses the symbol ≥, because the population P of
Baker can equal 16,202 or it can be greater than 16,202. So, P ≥
16,202.
Substitute x = 1.5 into the function:
f(1.5) = -16(1.5)^2 + 112 = -16(2.25) + 112 = -36 + 112 = 76
The object was 76 feet high, 1.5 seconds after it was released.
The total earnings will be base salary plus commission. The base salary is
$10,000. The commission is 15% of $90,000, or $13,500. The total base
salary plus commission is $23,500.

Use the FOIL method to distribute the terms of the first
binomial to the second binomial.
(3x + 4)(2x − 5) = 3x(2x) + 3x(−5) + 4(2x) + 4(−5)
= 6x^2 − 15x + 8x − 20
= 6x^2 − 7x − 20

This equation can be
solved by factoring,
however, the Quadratic
"Ten less than" means minus 10,
Formula will be used here:
and "twice" means times two.
x = 8 ± √64 − 4 ⋅ 3 ⋅ 5/ 2 ⋅ 3 The expression is 2m − 10 .
