Instructions: Find the missing side of the triangle. 30 х 50 X=

Mathematics
1 answer:
olga nikolaevna [1]3 years ago
3 0

Answer:

x = 40

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + 30² = 50²

x² + 900 = 2500 ( subtract 900 from both sides )

x² = 1600 ( take the square root of both sides )

x = \sqrt{1600} = 40

What are the dimensions of a 2x4x8
Vlad [161]

Answer:   Many of you know this, but why is this a thing? You don't go to Subway and pay for a $5-footlong expecting to get 11 inches (although many of you will argue this is the case). And it's not just a 2x4: A 1x4 is actually ¾ inches by 3-½ inches; a 4x4 is actually 3-½ inches by 3-½ inches.

Step-by-step explanation:

5 + 6 - (-3) - 8 + 4 -3
Komok [63]
Okay, so -

We have one very important thing here. This little part <em>6 - (-3). </em>

Now, it's essential to remember that when we have two negatives like this, we simply draw a line straight down. It becomes a positive! 

So, our question is essentially <em>5 + 6 + 3 - 8 + 4 - 3 = ?</em> instead of <em>5 + 6 - (-3) - 8 + 4 - 3!</em> =)

With that in mind, we simply solve left to right. 

<em>11 + 3 - 8 + 4 - 3 = ?</em>

<em>14 - 8  + 4 - 3 = ?</em>

<em>6 + 4 - 3 = ?</em>

<em>10 - 3 = ?</em>

<em>7</em> is our final answer! =)

Ruben bought 6 new books for his collection. This increased his collection by 12%. How many books does he have now?
Helen [10]
Let's create a variable to represent the size of Ruben's book collection prior to his buying the new books.  

B = number of books in Ruben's collection before buying new ones

So, we know that when he bought 6 books, this increased his collection by 12%.

12% of his book collection would be represented by 0.12B.  Therefore, we know that:

0.12B = 6

Divide both sides by 0.12, to get to B = 50.

However, you are being asked how many books does he have now.  B represents the number of books he had before.  Therefore you want to add back the 6 books he just bought.

The answer is 50 + 6 = 56
