Using a formula estimate the body surface area of a person whose height is 150 cm and who weighs 80 kg.

ladessa [460]

Answer:

B. $1.83\text{ m}^2$

Step-by-step explanation:

We are asked to find the body surface area of a person whose height is 150 cm and who weighs 80 kg.

$\text{Body surface area}( m^2)=\sqrt{\frac{\text{Height (cm)}\times \text{Weight (kg)}}{3600}}$

Substitute the values:

$\text{Body surface area}( m^2)=\sqrt{\frac{150\text{ cm}\times 80\text{(kg)}}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{\frac{12,000}{3600}}$

$\text{Body surface area}( m^2)=\sqrt{3.3333333}$

$\text{Body surface area}( m^2)=1.825741$

$\text{Body surface area}( m^2)=1.83$

Therefore, the body surface area of the person would be 1.83 square meters.

Can someone help me find AB and BC

Bond [772]

3x + 2x + 5 + 5x + 15 = 180 [angles on a line add to 180 degrees]
10x + 20 = 180 [combine like terms]
10x = 160 [subtract 20 from both sides]
x = 16 [divide both sides by 10]

Arc AB measures 3(16) = 48 degrees.

Arc BC measures 2(16) + 5 = 41 degrees.

Find the average for each group. Round to nearest tenth.<br><br> 6.8, 5.6, 3.4, 2.5, and 4.7.

mash [69]

Answer:

4.6

Step-by-step explanation:

Hello!

To find the average we add all the numbers together and divide by how many numbers we added

6.8 + 5.6 + 3.4 + 2.5 + 4.7 = 23

We added 5 numbers so divide the total by 5

23/5 = 4.6

The answer is 4.6

Hope this helps!
