30 (miles) times 4 (hours) equals to 120 miles. 400 miles minus 120 miles equals 280 miles (distance the other car has driven). 280 divided by 4 (because we want to find the speed for only one hour) equals 70 miles.
The average speed of the other car is 70 mph
Answer:
the 3rd one.
Step-by-step explanation:
-11 is the smallest number, followed by -1, the numbers are then listed correctly in an increasing order after that.
To find the area of the shaded piece, subtract the square area to the area of the sector.

Step-by-step explanation:
Answer:
| 10 -10 1 |
| 1 -2 -4 |
| -8 13 -24|
Step-by-step explanation:
First multiply each element in matrix A, this gives:
| -6 - 2 -3 |
| 1 -6 -4 |
| -4 5 0 |
Now we multiply each element in matrix B by 4, this gives:
| -16 8 -4 |
| 0 -4 0 |
| 4 -8 24 |
Finally subtract this from the first matrix ( subtracting element by element) gives:
| 10 -10 1 |
| 1 -2 -4|
| -8 13- 24|
