After jogging 3 miles bobby checked his heart rate he counted 30 beats and 15 seconds what would his heart rate be for one minute

Step-by-step explanation:

First, i would add 15 until you get to 60, or divide.

15 / 60 = 4

Then multiply 30 by 4:  30 X 4 =120.

120 is the awnser.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
