Answer:

15%

Step-by-step explanation:

Formula to find percentage increase/decrease/multiplier:

NV = OV x m

In words: New value = Old value x multiplier

In this question we're looking for the m (multiplier), so rearrange the formula and make m the subject.

m = NV / OV

So NV is the increase: 3162.50

OV = 2750

So 3162.50 / 2750 = 1.15

This is the multiplier (1.15) so turn into percentage by multiplying by 100 then subtract by 100.

1.15 * 100 = 115 - 100 = 15%

And the fact that the number is postive is proof that price has increased, if it was decrease, you would be expecting a negative number. Hope you understood. :)

ivanzaharov [21]

Answer:

Unit rate by which the runner completed the marathon is 0.13 miles per minute.

Step-by-step explanation:

A runner competed a marathon of 26.2 miles in 210 minutes.

we can get unit rate by unitary method.

∵ In 210 minutes a runner completes the distance = 26.2 miles

∴ In 1 minute runner will complete the distance = $\frac{26.2}{210}$

= 0.125 miles per minute

≈ 0.13 miles per minute

Therefore, unit rate by which the runner completed the marathon is 0.13 miles per minute.

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.
