It took a space shuttle 8 minutes 36 seconds to launch and reach outer space. How many seconds did it take? give u 1009 points later I promise

Answers

(8×60)+36
=480+36
=516 seconds
Multiply 8 by 60 = 480 add 36= 516
Therefore it took 516 seconds for takeoff

the answer is 78.5 because the formula to find area is πr2 so the radius is 5ft π is 3.14 so 3.14 times 5 and the 2 on top of r means the u have to do 5 times 5 which is 25 now it's real simple do 3.14 times 25 which is 78.5 I HOPE THIS HELPS=)

You would more than likely use a ruler. You can explain why you agree on it.
A ruler because using other things like a protractor wouldn't really make sense

The admission for a fair is $6 for adults, $4 for children, and $3 for senior citizens. Twelve people paid a total of $50 for admission. If 8 children attended, how many adults and senior citizens attended?

Answers

ok so total value=adultvalue+seniorvalue+childrenvalue
8 children
12people total so
12-8=4
4=adults+seniors
4=total amount of aduls and seniors
(if you want exacta amount, 2 adults and 2 seniors)
$32dallers in children
2 adalts=$12
32+12=$44
2 senior citizens=$6
44+6=50
2 senior citizens and adalts

The rise and span for a roof are shown. The pitch of a roof is the ratio of the rise to the half-span. If the rise is 8 feet and the span is 30 feet, what is the pitch in simplest form?

Answers

Half-span is half of span. Pitch of the roof is calculated as rise/(span/2). In this case, rise is 8 feet and span is 30 feet. So, the pitch can be calculated as 8/(30/2) or 8/15. Pitch is normally represented as the number of inches of rise per foot. So, to reduce 8/15 to match a foot, we multiply it by 12. So, (8/15) * 12 gives us 6.4 inches of rise per foot.

The pitch or slope of a roof is defined as the ration of rise and half of the span. In equation we can write:

Pitch=(Rise)/(Half-span)

Half-Span equals the run. So we can define the Pitch as:

Pitch = (Rise)/(Run)

Rise = 8 feet

Run = Half of span = 15 feet

Using the values in the above formula, we get:

Pitch = (8)/(15)

Therefore, the pitch (or slope) of the roof in simplest form is 8/15

Pitch is normally defined as the vertical rise of a roof for ever 12 feet increase in its horizontal run. The above fraction shows the vertical rise is 8/15 for each 1 feet increase in the horizontal run. So if we simply multiply the the above fraction by 12, we will get the pitch in standard units.

So,

Pitch = 8/15 x 12 = 6.4

Therefore, the pitch of the roof will be 6.4
