Rachel wants to buy a shirt regularly priced at $32. It is on sale for 40% off. Rachel estimates that she will save 2/5 of $30 o
1 answer:
Okay, so first you know that the shirt was priced at $32.
It's on sale for 40%.
40% =
Now we can make a proportion, so set the values in a fraction.
We put 32 on the bottom since it's the total amount.
Divide 100 by 32, so 100÷32=3.2
Now divide the numerator (40) by 3.2, so 40÷3.2=12.5
That means the new cost of the shirt is $12.50 so the new amount will be more than 12 dollars.
Hope that helped :)

The area of the considered triangle RST is given by: Option A: 9 sq. units.
<h3>How to find the area of a triangle?</h3>If we have:
- Length of its base = b units
- Its height = h units long,
Then we get:
Area of a triangle =
The missing image is attached below.
If we take the base of the triangle as RS, then as the line UT is perpendicular to RS (as RS is parallel to x axis and UT is parallel to y axis) and touching from the base line RS to T, thus, it can be taken as height.
Thus, we have:
Area of RST = half of length of RS (base) times length of UT (height)
As visible from image, we have:
Length of RS = 6 blocks of unit length = 6 units
Similarly, length of UT = 3 units
Thus, we get:
Area of RST =
Thus, the area of the considered triangle RST is given by: Option A: 9 sq. units.
