Well a million is 1,000,000,000. So 320,000,000,000 has 1" zeros
Answer:
1. More magnets are longer than 2 1/2
2. 10 magnets measure in whole numbers and 5 magnets between 2 whole numbers
3. Because the shortest magnet is 1 inch and the longest magnet is 4 inches.
Step-by-step explanation:
1. There are 7 magnets that are longer than 7 1/2 and only 6 magnets that are shorter than 2 1/2. (The 2 magnets that are exactly 2 1/2 are neither longer nor shorter therefore they do not apply to the question.)
Answer:
Step-by-step explanation:
Since we have been given height of triangle as 8 and length of its base as 3. We can use similar triangles to express the base of the smaller triangle in terms of h.
The height of the smaller triangle will be
Let x be the base of the smaller triangle. Therefore, using similar triangles, we can set the ratios of corresponding sides of the two triangles equal to each other as shown below:
Now, we can express the area of the small rectangular strip of length x and thickness Dh as shown below:
Therefore, the required Riemann sum can be expressed as:
The required areas can be expressed as:
Rest of your answers are correct. :)
