The vertices on the major axis are:
(

)
The vertices on the minor axis are:
(
h

)
and
(

35 divided by 2.5 is 14, so she biked 14 miles in 1 hour. So 14*3= 42
She can bike 42 miles in 3 hours.
Answer is $3.92
Step by step
Using PEMDAS we perform the math inside the Parenthesis first. (5.80 + .28) = 6.08
Now we have $10 - 6.08 = $3.92

hope you understand. please mark me brainliest. you have no idea how much times e checked the
arrangements before.
Triangle Area = .5 * (base * height)
36 = (base * height) / 2
So let's say base = 9 height 8
If base and height are scaled by a factor if 5 than
base = 45 height 40 and
area = .5 * (45 * 40)
area = 900
Basically, the area increases by a factor of 25.
The base increases by 5 and the height increases by 5 so the area increases by 5*5 = 25
