Answer:

x = 7

Step-by-step explanation:

0 = 4(x+5) + 8

expand:

0 = 4x + 4*5 + 8

0 = 4x + 20 + 8

0 = 4x + 28

simplify

4x = 28

simplify

x = 28 / 4

x = 7

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 :)

Mkey [24]

Answer:

At least 16 calls must be made.

Step-by-step explanation:

It is given that Joes electric made 19 customer calls last week and 25 this week.

Let x calls be made next week in a order to maintain an average of at least 20 calls per week for three week period.

Average=\dfrac{\text{Sum of observations}}{\text{Number of observations}}

Average=\dfrac{19+25+x}{3}

Average=\dfrac{44+x}{3}

Average at least 20.

Average\geq 20

\dfrac{44+x}{3}\geq 20

44+x\geq 60

x\geq 60-44

x\geq 16

Hence, at least 16 calls must be made.
