Problem 1.
1 day = 24 hours
58 days = 24 * 58 = 1392 hours
60 minutes = 1 hour
30 minutes = 30/60 hour = 1/2 hour
It takes Keurig a total amount of time of 1392 + 15 + 1/2 = 1407 * 1/2
Problem 2.
Part A: 1 foot = 12 inches 0.5 feet * 12 inches = 6 inches per day
Part B: 1 day = 24 hours 6 inches/24 hours = 0.25 inches per hour
What you need to do step 1 y=6-7
step 2 y=1
then you make an ordered pair with the x and y
then graph
<u>7.1 cm long is the arc</u><u> intersected by a central angle .</u>
What is length of an arc?
- The arc length of a circle can be calculated with the radius and central angle using the arc length formula.
- Length of an Arc = θ × r, where θ is in radian. Length of an Arc = θ × (π/180) × r, where θ is in degree.
Given,
Central angle = π / 2
radius = 4.5 cm
we apply formula of length of arc.
length of the arc = angle × radius
= (π/2) × (4.5 cm)
Now put value of π = 3.14
length of the arc = (3.14 / 2) × (4.5) cm
= 7.065 cm ≈ 7.1 cm
Therefore, 7.1 cm long is the arc intersected by a central angle .

Answer:
(c) 11
Step-by-step explanation:
As x goes up by 1, f(x) goes up by 2. The next line of the chart would be ...
x = 4+1 = 5; f(x) = 9+2 = 11
The appropriate choice is f(5) = 11.
Answer:
19,23
Step-by-step explanation:
9+x-7≥ 21
Combine like terms
2+x≥21
Subtract 2 from each side
2+x-2 ≥21-2
x≥19
Any number greater than or equal to 19
