Answer:
Daniel is rollerblading at 15 miles per hour
Daniel can go 3 miles in 12 minutes so we do 12÷3 to find out how many minutes it takes to go 1 mile which is 4 now we do 60÷4 to get 15
Alternatively we could do 60÷12 to get 5 then do 3×5 to get 15
Step-by-step explanation:

The answer is B
Step-by-step explanation:
2021 - 1962 =59
59-13=46
2021-46=1975
Then 7+3=10
Answer: 12
Step-by-step explanation:
Lucy draws a line on a coordinate plane. We have to identify the transformation which will always result in a line perpendicular to Lucy’s line.
Referring to the given options.
By rotating 270 degrees clockwise around the origin, Lucy will get a line perpendicular to the Lucy's line. As, when we rotate 270 degrees clockwise about the origin, we multiplies the x coordinate by '-1' and interchanges the x and y coordinate, which gives the line which is always perpendicular to the Lucy's given line.
Answer:
The total number of books is 1020.
Step-by-step explanation:
