Answer:
Hight times base equals area
Step-by-step explanation:
The unit rate for Leo's reading is 20 pages per hour and 0.05 hours per page.
To find the unit rate for pages per hour, we need to adjust Leo's reading speed to reflect a full hour rather than half an hour. Since he reads 10 pages in half an hour, then in a full hour, which is twice as long, he would read twice as many pages. So, Leo's rate in terms of pages per hour is 20 pages per hour.
To find the unit rate for hours per page, we flip the ratio. So instead of looking at it as 'pages over hours,' we're looking at it 'hours over pages'. Leo reads 10 pages in half an hour, that is 1 page in 1/20 of an hour (or 0.05 hours). Therefore, his rate in terms of hours per page is 0.05 hours per page.

Answer:
0.1 = 4.73. Dividing 47.3 by one tenth you get 473.
Answer:
87,120 ft²
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Surface area of the Empire State building replica = 45 square feet
Scale factor = 44
2. What is the surface area of the actual Empire State Building in square feet?
For answering the question, we will make the following calculations:
45 square feet = 9 feet * 5 feet or,
45 square feet = 10 feet * 4.5 feet, or,
45 square feet = 20 feet * 2.25 feet.
Now, let's apply the scale factor to all of these probable lengths of the sides of the surface area of the replica, as follows:
(9 *44) * (5 * 44) = 396 * 220 = 87,120 ft²
(10 * 44) * (4.5 * 44) = 440 * 198 = 87,120 ft²
(20 * 44) * (2.25 * 44) = 880 * 99 = 87,120 ft²
As we proved, no matter what are the lengths of the sides of the surface area of the replica. after applying the scale factor, the result is the same: 87,120 ft²
