Answer:
701 revolutions
Step-by-step explanation:
Given: Length= 2.5 m
Radius= 1.5 m
Area covered by roller= 16500 m²
Now, finding the Lateral surface area of cylinder to know area covered by roller in one revolution of cylindrical roller.
Remember; Lateral surface area of an object is the measurement of the area of all sides excluding area of base and its top.
Formula; Lateral surface area of cylinder= 
Considering, π= 3.14
⇒ lateral surface area of cylinder= 
⇒ lateral surface area of cylinder= 
∴ Area covered by cylindrical roller in one revolution is 23.55 m²
Next finding total number of revolution to cover 16500 m² area.
Total number of revolution= 
Hence, Cyindrical roller make 701 revolution to cover 16500 m² area.
Since the 4 sectors of the spinner are equal, the probability of spinning any one of them is 1/4. Coins are always 50/50, so the probability of tossing a head with a penny is 1/2. Since the question is spinning C AND tossing a head with a penny, you must multiply the two previously found probabilities. 1/4 times 1/2=1/8 so 1/8 is the answer.
The road trip is 2916 miles long, if she wants to complete the trip in 6 days she will need to drive ___ miles per-day.
To figure this out we will need to divide 2,916 by 6 days
2,916/6 = 486 miles
Answer:
B. y - 35 = 2(x - 10)
Step-by-step explanation:
The height of the plant, y, after x days could be modeled by the equation
<h3>y-y0=k(x-xo) (1)
,</h3><h3>
where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.</h3><h3>
From equation (1), k could be evaluated as follows:</h3><h3>
k=(y-y0)/(x-x0) </h3><h3>
From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.</h3><h3>
Thus,</h3><h3>
k=(55-35)/(20-10)=2</h3><h3>
Therefore, the model equation becomes</h3><h3>
y-35=2(x-10)</h3><h3>
</h3>
I believe it would be Y=1.5x I say this because x represents the seconds and they can type 1.5 words Per second so you would be 1.5x and Y is the number of words which would be the solution at the end of the problem, this is why you put Y=
