No, -(5/11) is equivalent to -5 all over 11 so -5/11. You cannot change the denominator

Find the quotient. If possible, rename the quotient as a mixed number. Select the answer that is in simplest form. 3/5 ÷ 1/2 =

Vanyuwa [196]

3/5 divided by 1/2 equals 6/5 or 1 and 1/5!
(My method- Keep 3/5, change the division sign to a multiplication sign, and flip 1/2 to 2/1. Multiply strait across and you get 6/5! 5 can go into 1 one time and that leaves 1/5! So your answer is 1 and 1/5! Hope it helps!)

Find the area of triangle DEF with vertices D(-1,2), E(3,-2) and F(-2,-2).*

Veronika [31]

Answer:

The area of the triangle DEF is 10.

Step-by-step explanation:

Area of a Triangle:

A triangle of base B and height H (both must be perpendicular) has an area of:

$\displaystyle A=\frac{BH}{2}$

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:

$\displaystyle A=\frac{5*4}{2}=10$
