Answer:The number of words that she would still have to type to finish her essay is 1000
Step-by-step explanation:
Karen is typing a 4,000 word essay. She can type at about 30 words per minute. This means that if her rate remains constant, the total number of minutes that it will take her to finish would be
4000/30 = 133.33 minutes.
If she types for 45 minutes on Monday, it means that the total number of words that she typed on Monday would be
45 × 30 = 1350 words
If she types for 55 minutes on Tuesday, it means that the total number of words that she typed on Tuesday would be
55 × 30 = 1650 words
Total number of words typed on Monday and Tuesday would be
1350 + 1650 = 3000 words
The number of words that she would still have to type to finish her essay would be
4000 - 3000 = 1000 words
If you want to keep it technical, the normal “/unit rate” for running is minutes per mile. You can use dimensional analysis like I did below to find the answer. You should get 11.45 min/mile or about 11 min 25 sec per mile
Answer:
Volume of the frustum = ⅓πh(4R² - r²)
Step-by-step explanation:
We are to determine the volume of the frustum.
Find attached the diagram obtained from the given information.
Let height of small cone = h
height of the large cone = H
The height of a small cone is a quarter of the height of the large cone:
h = ¼×H
H = 4h
Volume of the frustum = volume of the large cone - volume of small cone
volume of the large cone = ⅓πR²H
= ⅓πR²(4h) = 4/3 ×π×R²h
volume of small cone = ⅓πr²h
Volume of the frustum = 4/3 ×π×R²h - ⅓πr²h
Volume of the frustum = ⅓(4π×R²h - πr²h)
Volume of the frustum = ⅓πh(4R² - r²)
