To find how many words James can type in 30 seconds, we need to fill in the missing value in the table.
Since James can type 40 words in 20 seconds, we can set up a ratio to solve for x:
40 words / 20 seconds = x words / 30 seconds
To solve for x, we can cross-multiply:
40 * 30 = 20 * x
1200 = 20x
To isolate x, divide both sides of the equation by 20:
1200 / 20 = x
60 = x
Therefore, James can type 60 words in 30 seconds. Answer: 60

To find how many free throws Nancy can make in 10 minutes, we need to use the ratio provided in the table:
7 free throws / 1 minute = y free throws / 10 minutes
To solve for y, we can cross-multiply:
7 * 10 = 1 * y
70 = y
Therefore, Nancy can make 70 free throws in 10 minutes. Answer: 70.

How many math problems can she complete in 1 minute? How many math problems can she complete in 15 minutes? (1 point) Responses 9; 23 9; 23 6; 90 6; 90 7; 22 7; 22 24; 72 24; 72 Skip to navigation
To find how many math problems Jesse can complete in 1 minute, we need to use the ratio provided in the table:
48 math problems / 8 minutes = x math problems / 1 minute
To solve for x, we can cross-multiply:
48 * 1 = 8 * x
48 = 8x
To isolate x, divide both sides of the equation by 8:
48 / 8 = x
6 = x
Therefore, Jesse can complete 6 math problems in 1 minute.
To find how many math problems Jesse can complete in 15 minutes, we can use the same ratio:
48 math problems / 8 minutes = y math problems / 15 minutes
To solve for y, we can cross-multiply:
48 * 15 = 8 * y
720 = 8y
To isolate y, divide both sides of the equation by 8:
720 / 8 = y
90 = y
Therefore, Jesse can complete 90 math problems in 15 minutes.
Answer: Jesse can complete 6 math problems in 1 minute and 90 math problems in 15 minutes.
