If Joe's heart beats 1,200,703 times
professor190 [17]

11 days, 21 hours, and 52 minutes have elapsed

(this answer is assuming he would have a normal heart rate of 70 bpm)

First, you would divide 1,200,703 by 70:

1,200,703/70=17,152.9

This is the amount of minutes that have elapsed.

Then, you convert the minutes to hours by dividing by 60:

17,152.9/60=285.8816667 (285 hours and 52 minutes)

This gives you how many hours and minutes have elapsed.

Finally, you calculate the number of days that have elapsed by dividing 285 by 24 (there are 24 hours in a day):

285/24=11.875 (11 days and 21 hours).

Put all of the amounts together to get the final answer:

11 days, 21 hours, and 52 minutes have elapsed

Solve the system by graphing: y=-3x-3 and y=2x+2. Make sure you write your answer as an ordered pair: (x,y)
Rainbow [258]

Answer: (5, 12)

Step-by-step explanation:

Just graph the linear equations and find where they intersect.

Algebraically, you can set them equal to each other

-3x-3=2x+2

-x-3=2

-x=5

x=5

Plug x=5 to any equation

y=2(5)+2

y=12

Slope -2/3, through (-1,-6) <br><br> What is the equation of the line?
Arturiano [62]

Answer:

Step-by-step explanation:

y + 6 = -2/3(x + 1)

y + 6= -2/3x - 2/3

y + 18/3 = -2/3x - 2/3

y = -2/3x - 20/3

Please help and show work!
Ierofanga [76]

Answer:

x = 3

Step-by-step explanation:

Two triangles are similar

x/(x+3) = 4/8 cross multiply expressions

8x = 4x + 12

8x - 4x = 12

4x = 12 divide both sides by 4

x = 3
