The answer is 7, hope it’s right
PART A
Coefficient
Coefficient h is 7.50
Coefficient s is 0.20
Variable
h and s
Constant
40
PART B
7.50h + 0.20s + 40
= 7.50(25) + 0.20(300) + 40
= 187.5 + 60 + 40
= 287.5
She earns $287.5
PART C
Yes, the coefficient of h would change to 9, the rests are still the same. Because she's no longer receive 7.50 per hour, and start earning 9 per hour, so the coefficient should change.
The expression would be
9h + 0.20s + 40
4, 12, and 18 in two different ways
<span>(4 + 12) + 18 = 16 + 18 = 34
4 + (12 + 18) = 4 + 30 = 34
answer is B) </span><span>(4 + 12) + 18 = 16 + 18 = 34; 4 + (12 + 18) = 4 + 30 = 34 (second choice)</span>
Answer:
Step-by-step explanation:
BC = 60
CA = 45
AB = sqrt(45^2 + 60^2)
AB = sqrt(2025 + 3600)
AB = sqrt(5625)
AB = 75
