Answer:
A. 24.2°
Step-by-step explanation:
I'm correct if I'm rwong
1. square base area= 25 inches
2. using the slanted 6.5
=1/2base , therefore 5/2=2.5 inches
3. then use pythagoras.... c=6.5, a=2.5
c^2=a^2 + b^2
(do this urself)
4. when u find what b is... that's the height of one of the triangle
base= 2.5 (look at step 2 if u don't understand this bit)
height=b (refer to step 3)
5. then work out the area of 1 triangle using that...
6. then have (the answer u work out in step 5 ) multiply 4
this will give u the area for the all of the 4 triangles...
7. Then add together the square based area in step 1..(25)
to the 4 triangular, area faces (i.e from step 6) - the total will be ur answer for the amount of cardboard!!
p.s don't forget the units!!!
Answer:
the answer should be 2.04
Step-by-step explanation:
Answer:x=20
Step-by-step explanation:
Given
selling Price of Toy is x dollars
he can sell 40-x toys each week
Thus Revenue Generated from selling 40-x toys at x dollar can be given by

To get maximum Revenue differentiate R with respect to x and equate it to 0
therefore 


thus for maximum Revenue owner sells 20 toys each week
Max Revenue
Lets first simplify the dimensions of the rectangle
length = 7
breadth =

=

= 0.6
The area of rectangle = length * breadth
so, area of rectangle = 7 * 0.6
Area of rectangle = 4.2
Hope it helped you.. :D
