First, convert the 75% to a real mathematical number. For percents, this is always done by dividing the 75% by 100%, or 75% / 100% = 0.750.
Second, find out what 75% of $120 is. This is the amount of the sale discount. This is always found by mulitplying 0.750 by the item's cost $120, like this:
0.750 x $120 = $90.00.
So for this sale, you'll save $90.00 on this item.
This means, the cost of the item to you is
$120 - $90.00 = $30.00.
Alternatively, you can think about it this way. The item is 75% off. This means you'll pay 25.000% of the total cost (100% - 75% = 25.000%).
Now what's 25.000% of the total cost?
0.250 x $120 = $30.00.
Just like the result above, the sale price on the item is $30.00.
Hope this helps you! Brainliest? :)
Answer:
f. for the x values I think its -1 & 5
Answer:
The ares in factorised form is C. (x-8)(x-6)
When expanded it is G. x^2-14x+48
Step-by-step explanation:
The rectangular photo is mounted on a piece of board whose sides have length x. The border that surrounds the photo is 3 inches on each side and 4 inches on both the top and the bottom.
Area of rectangle is length × breadth
Length of rectangle (x - 4 - 4) = (x - 8) inches
Breadth of rectangle (x -3 - 3) = (x -6) inches
Thus, area of photograph = (x - 8)(x -6) inches².
Expanding it by opening the bracket
x(x-6)-8(x-6)= x^2-6x-8x+48=x^2-14x+48
Thus; C and G is correct
Answer:
The volume of the prism is
Step-by-step explanation:
we know that
The volume of the prism is equal to
where
B is the area of the equilateral triangle of the base
h is the height of the prism
step 1
Find the area of the base of the prism
The formula to calculate the area of a triangle by SAS (side-angle-side) is equal to
so
The area of the equilateral triangle of the base is
we have
substitute
step 2
Find the volume of the prism
we have
substitute
To calculate the area of this parallelogram first you have to solve 18 to the power of 2. If you look at point A you see it says 45 degrees. So it should subtract 180 from the 45 degrees to get your total angle degrees. After that you multiply to find your answer
