HeLp. "How many times does a person's heart beat in their life? How many gallons of blood does it pump? (Estimate that the heart pumps 50 3 of blood in each beat, you should take as a reference its beats per minute and an average life of 70 years)"

144.50

step-by-step explanation:

21.5 x 13.4=288.10 divide by 2

answer: i feel you honey.

step-by-step explanation:

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
