What is a better deal 56/25 or 32.05/15
1 answer:
We are given fractions: .
Let us convert those both fractions in decimals only to get the better deal.
For first fraction 56/25, if we divide 56 by 25, we get
56 ÷ 25 = 2.24 decimal value.
And for second fraction 32.05/15 if we divide 32.05 by 15, we get
32.05 ÷ 15 = 2.14 (approximately).
2.14 is lesser value, therefore 2.14 is better deal than 2.24.
And finally we could say 32.05/15 is better deal than 56/25.

Answer:
<em>The area of the triangle DEF is 10.</em>
Step-by-step explanation:
<u>Area of a Triangle:</u>
A triangle of base B and height H (both must be perpendicular) has an area of:
The image below shows the triangle formed by the points DEF. It's important to notice the points E and F lie on the same horizontal line because they both have the same y-coordinate.
This fact simplifies the calculations since we can easily compute the length the of base as the difference of their x-coordinates:
B=3-(-2)=3+2=5
Being the base of a horizontal line, the height of the triangle can be calculated as the difference of y-coordinates of D and the height of that line.
H=2-(-2)=4
With these two values, we calculate the area:
The area of the triangle DEF is 10.
The answer will be y^2/4 (I’ve written up properly on the photo as I can’t type it)
