Answer:
t = 3.46 hours, or 3 hours 28 minutes
Step-by-step explanation:
78 dozen donuts in 2 hours immediately reduces to 39 dozen/hour.
Donuts produced as a function of time: D(t), where t is the number of hours the macine runs.
Set D(t) = 135 dozen = (39 dozen/hr)t.
Solving this equation for t, we get:
t = 135/39 hours, or t = 3.46 hours, or 3 hours 28 minutes
Answer:
a) Buddy's Unit rate is 11 minutes per 1 mile.
Jovie's unit rate is 10 minutes and 30 seconds or 10.5 per 1 mile.
A unit rate is the amount per one unit.
b) 5 miles. Or if Buddy and Jovie count their miles separately then 10 miles together since each runs 5 miles.
Step-by-step explanation:
a) A unit rate is the amount per one unit. At a grocery store, the unit rate is dollar cost per 1 unit bought. In a race, the unit race is the time it takes to one 1 mile.
Since Buddy can run 1/2 a mile in 5 minutes and 30 seconds, we can double his time for a full mile. 2*5 min is 10 minutes and 2*30 sec is 60 seconds or 1 minute. Buddy runs 11 minutes per mile.
Since Jovie can run 1/2 a mile in 5 minutes and 15 seconds, we can double the time for a full mile. 2*5 min is 10 minutes and 2*15 sec is 30 seconds. Jovie runs 10 minutes and 30 seconds per mile. This can also be written as 10.5 mins per mile.
b) Because we know how long it takes to run 1 mile, we can calculate how many miles can be run in a specific time frame by dividing it by the unit rate. An hour has 60 minutes. Divide 60 by Buddy's unit rate. 11 minutes per 1 mile. 11 divides into 60 to give 5.4545454....miles. We round up or down to the nearest mile to give 5 miles completed in 1 hour. If each runs 5 miles then together they run 10 miles.
The answer is A my dude, this is easy math lol

Plz name me brainliest
Based on the area of the tabletop with the inner circle, the area after the inner circle has been cut out is 12,309 inch².
<h3>How do we find the new area of the tabletop?</h3>
We are told that the area of the tabletop is 12,463 inch².
We then need to find the area of the circlular cutout as:
= π x radius x radius
= 3.14 x 7 x 7
= 154 inch²
The new area after the cutout is removed is therefore:
= Current area - area of circular cutout
= 12,463 - 154
= 12,309 inch ²
Rest of the question:
Area of table including the cutout is 12,463 square inches.
