Use the formula πd.
The medimum has a diameter of 10π and the large has diameter of 12π. The difference is 2π or 6.28 inches. The third one.:D
31.
8 + x/3 = -2
Substract both sides by 8:
x/2 = -10
Multiply:
x = -20
33.
6 * (x + 15) = -42
We can divide both sides by 6:
x + 15 = -7
Substract both sides by 15:
x = -22
Step-by-step explanation:
Rotation of 90° clockwise about the origin
Answer:
<em>11w + 6g ≥ 120</em>
Step-by-step explanation:
Let's set:
w = number of hours Lauren spent washing cars
d = number of hours Lauren spent walking dogs
Lauren makes $11 per hour washing cars, thus she earns 11w in total for washing cars.
Lauren makes $6 per hour walking dogs, thus she earns 6d in total for walking dogs.
The total earnings are:
T = 11w + 6g
Lauren must earn not less than $120 this week, thus:
11w + 6g ≥ 120
This is the required inequality
