Calculate the length of AB. Round to the nearest tenth.
marissa [1.9K]

Answer:

AB = 10.06 cm

Step-by-step explanation:

Consider the given figure,

We have to find the length of side AB.

Lets rename the figure first, ABCD forms a rectangle. So , CB = DA = 12 cm

Also, EA = ED +DA ⇒ 15 = ED + 12 ⇒ ED = 15 - 12 ⇒ ED = 3 cm

Pythagoras theorem states that in a right triangle the sum of square of base and perpendicular is equal to square of hypotenuse.

Using, Pythagoras Theorem on Δ EDC,

(EC)^2=(ED)^2+(DC)^2

ED = 3 cm , EC = 10.5, Substitute, we get,

\Rightarrow (10.5)^2=(3)^2+(DC)^2

Solve for DC, we get,

\Rightarrow 110.25=9+(DC)^2

\Rightarrow 110.25-9=(DC)^2

\Rightarrow (DC)^2=101.25

\Rightarrow DC=\sqrt{101.25}

\Rightarrow DC=10.06

Since, ABCD is a rectangle. Thus, DC = AB

Hence, AB = 10.06 cm

Suppose a person eats 2000 food calories on average per day. Note that 1 calorie= 4.184 joules and a food calorie = 1000 calorie
Crazy boy [7]

Answer: 0.097\text{\ J/s}

Step-by-step explanation:

Given :  1 calorie= 4.184 joules

A food calorie = 1000 calories = 4184 joules.

Then, 2000 food = 2\times4184=8368 joules   [By Unitary method]

We know that : \text{Power}=\dfrac{\text{Energy}}{\text{Time}}

Since 1 day = 24 hours

and 1 hour = 3600 seconds

Then, 24 hours = 24\cdot3600=86400 seconds.

Now,   \text{Power}=\dfrac{8368}{86400}

=0.0968518518519\approx0.097\text{\ J/s}

Hence, the average power of this intake = 0.097\text{\ J/s}
