The sun burns 6 million tonnes of hydrogen a second. Calculate how many tonnes of hydrogen it burns a year (that's 365.25 days)

Illusion [34]

Your answer is 189,345,600,000,000 tons per year

There are 86,400 seconds in a day, and 365.25 days in a year. So 86,400*365.25= 31,557,600 seconds per year. Now if each second the sun burns 6 million tons we have to multiply that by the number of total seconds per year. So 31,557,600 * 6,000,000= 189,345,600,000,000 hydrogen tons per year.
Hope this helped :)

Micheal just moved here from Chicago. Micheal has red hair, therefore people from Chicago have red hair

Snezhnost [94]

Answer:

inductive

Step-by-step explanation:

Inductive reasoning is based on generalization, and making conclusions without hard evidence. If Micheal has red hair and is from Chicago, inductive reasoning draws the conclusion that everyone in Chicago has red hair. Deductive reasoning would be predicting that everyone in Chicago has red hair, and then testing it to see if you are right.

Flying against the wind, an airplane travels 4560 kilometers in 6 hours. Flying with the wind, the same plane travels 3720 kilom

Flura [38]

Answer:

The speed rate of the plane in still air is 1006.67 km/h

The speed rate of the wind is 246.67 km/h

Step-by-step explanation:

To answer the question, we let the speed of the plane in still air = x km/h

Let the speed of the wind = y km/h

Therefore,

4560/(x - y) = 6 hours and

3720/(x + y) = 3 hours

4560 = 6·x - 6·y.........(1)

3720 = 3·x + 3·y ........(2)

Multiplying equation (2) by 2 and add to (1) gives

12080 = 12·x

x = 12080/12 = $1006\frac{2}{3}$ km/h

Substituting the value of x in (1) gives

4560 = 6040 - 6·y

6·y = 1480

y = 1480/6 = $246\frac{2}{3}$

The speed rate of the plane in still air = 1006.67 km/h

The speed rate of the wind = 246.67 km/h.

Answers please! I’m finding the volume and i don’t really get it

MrRa [10]

Answer:

V = 13/2

Step-by-step explanation:

When finding volume you must know the formula on doing so.

<em>Volume = length × width × height</em>

length = $2\frac{1}{2}$ --> $\frac{5}{2}$

width = $2\frac{1}{2}$ --> $\frac{5}{2}$

height = $3\frac{1}{4}$ --> $\frac{13}{4}$

<u>mixed number --> fraction</u>

$V = \frac{5}{2} x \frac{5}{2} x \frac{13}{4}$

$V = \frac{25}{4} x \frac{13}{4}$

$V = \frac{325}{8}$ or $\frac{13}{2}$

Sin(11∘)cos(19∘)+cos(11∘)sin(19∘)

sergij07 [2.7K]

Recall that:

sin(A + B) = sinAcosB + cosAsinB

Therefore:

sin11°cos19° + cos11°sin19° = sin(11° + 19°)

= sin30° = 0.5

I hope this explains it.
