The answer is :
so, type 190 in the box
Step-by-step explanation:
Notice that there are three right angle triangles in the image given. In order to create equations associated with the Pythagorean Theorem for the three triangles, we add the letters x and z to identify two sides that are missing information. Please see attached image for reference.
In the small right angle triangle on the right, the Pythagorean theorem tells us:
In the larger triangle :
In the small triangle on the left:
and in this last equation we can substitute the z-squared and the x-squared by the expressions we got before in the other two equations:
Then to solve for "y" we apply the square root:
Answer:
4+2x
Step-by-step explanation:
Answer: 33
Step-by-step explanation: We can make an equation. 2:9 can be equal to 2x:9x. So 9x=27, x=3. Then if 9x=27, 2x= 3 times 2=6. 27 +6= 33.
$64 jacket with a 20% discount:
First, we need to change the percentage into a number that we can calculate with. Take the percentage (20%) and divide it by 100(%), since the denominator should always be 100 when changing a percentage into a decimal.
Now that we have a number we can calculate with, we need to know how much money we are going to save from the discount. Take the new decimal we just got, and multiply it by the cost of the jacket, which is $64.
×
Knowing that we can save $12.40 on the jacket, we can now subtract the price of the jacket from the discount we get on it.
You will pay a total of
$51.20 on the jacket with the discount added.
