3/8 times 2/5 is 6/40 or 0.15. Just multiply straight across
Number machines=100=10² machines.
number pages/1 machine=10⁴ pages/ machine.
number pages that can print 100 machines in a day=
=10² machines * 10⁴ pages/ machines=10²⁺⁴ pages=10⁶ pages/day.
necessary days to print 10⁶ pages=number pages/ number pages that can print 100 machines in a day.
necessarry days to print 10⁶ pages=10⁶ pages / 10 ⁶ pages/day=10⁶⁻⁶ days=
=10⁰ days=1 day.
1 day for print 10⁶ pages, whith 100 machines.
I'll do better than that ! I'll show you how to do it, because
the answer is no help if you don;t know how to work it out.
Do you see that little square in one corner of the triangle ? That tells you
that the angle there is 90 degrees, and THAT tells you that the triangle is
a RIGHT triangle. This is a very helpful piece of information, because there's
a rule about the sides of a right triangle that isn't true for any other kind of triangle. The rule is:
(the longest side)² = (one of the other sides)² plus (the third side)²
Also, the longest side is always the one that doesn't touch the 90-degree angle.
In this triangle in the picture,
-- the longest side is 'A' ... it's 13 .
-- one of the other sides is ' b ' ... it's 12 .
-- the third side is ' C ' ... the one you have to find.
Using the formula up above, you know that
(13)² = (12)² + C²
Before you go to work on it, subtract (12)² from each side of this equation,
just to make it a little easier, and then you have
<em> C² = (13)² minus (12)²</em>
And right there is how to figure out the length of ' C '.
I'll give you even more information to help you, and then it's up to you
to finish it and get the answer. Here it is:
(13)² = 169
(12)² = 144
Now you have everything you need. Go to it !
Given that there are six terms, we have this set:
So, we need to find a4 and a5. Given that:
-9-(-7) = -2
-11-(-9) = -2
Then, it is obvious that
∴
∴
Then, <span>the sum of the terms of the series is</span>:
Answer:
D. 5 packs of pens and 6 packs of notebooks
Step-by-step explanation:
5 packs * 6 per pack = 30 pens
6 packs * 5 per pack = 30 notebooks
