Pyramide-shaped gift boxes have square bases that measure 5 inches on each side.The slant height is 6.5 inches.How much cardboar
andrew-mc [135]
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!!!

A toy store owner estimates that by charging x dollars each for a certain toy, he can sell 40−x toys each week. The quadratic eq
djyliett [7]

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

R=-x^2+40x

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

therefore \frac{\mathrm{d} R}{\mathrm{d} x}=-2x+40

-2x+40=0

x=20

thus for maximum Revenue owner sells 20 toys each week

Max Revenue R=-(20)^2+40\times 20=-400+800=$ 400

Find The area of The rectangle below \ 7 FT 6/10 FT
hodyreva [135]
Lets first simplify the dimensions of the rectangle
length = 7
breadth = \frac{6}{10} = \frac{3}{5} = 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
