To solve this problem, we must first find the discount amount, and then subtract this amount from the total price of the item.
To find the discount amount, we must find 35% of $40. To do this, we must first convert 35% to its decimal equivalent by dividing 35/100. We do this because percentages are parts out of a total 100 percent, thus this fraction represents an equivalent value that we can multiply by other numbers. Using our knowledge that 35/100 = 0.35, we can now set up our expression:
35% of $40 (keep in mind that the word "of" refers to multiplication in math)
0.35 * 40
To solve, we just multiply these two numbers together, which gives us 14.
This means that Kala got a discount of $14 off of the original price of $40. To find out how much she paid for it, we must subtract $14 from $40, as modeled below:
$40 - $14 = $26
Therefore, Kala paid $26 for the item.
Hope this helps!
Answer: 340
Explanation:
In order to find the length of the diagonal of a rectangle you need to cut the rectangle in diagonal then you have 2 right triangle:
We can take one right triangle to work with:
We can use Pythagorean’s theorem to find the hypotenuse of the right triangle (also the diagonal of the rectangle):
a^2 + b^2 = c^2
300^2 + 160^2 = c^2
90000 + 25600 = c^2
115600 = c^2
Sqrt 115600 = c
340 = c
Where c is the hypotenuse of the right triangle and also the diagonal of the rectangle
3,153,007 rounded to the nearest 100,000 is 3,200,000.
