Answer:

1065

Step-by-step explanation:

A right square pyramid consist of

  1. 1 base area which is a square, area of square = l²
  2. 4 triangles, area of a triangle = 1/2 (slant height)(base)

                             area of 4 triangle = 2 (slant height)(base)

In question we are given perpendicular height of pyramid not the slant height so first we will calculate the slant height.

By using pythagorus:

Slant height = √(24²+8²)

                   = 8√10

Surface area = baseArea + 2 (slant height)(base)

                     = 16² + 2( 8√10)(16)

                     = 1065

The number 900 has an interesting property in that the only primes that divide into it evenly are 2, 3, and 5. What are the next
Tasya [4]

900 = 2 · 2 · 3 · 3 · 5 · 5

Next numbers:

2 · 2 · 2 · 3 · 3 · 3 · 5 · 5 · 5 = 900 · 15 = 13,500

2 · 2 · 2 · 2 · 3 · 3 · 3 · 3 · 5 · 5 · 5 · 5 = 13,500 · 15 = 202,500

202,500 · 15 = 3,037,500

3,037,500 · 15 = 45,562,500

gtnhenbr [62]

Answer:

190 *.80 *(1.05)

<em> Instead of adding the sales tax, he subtracted the sales tax. </em>

159.60

Step-by-step explanation:

If Joel gets 20% off, he still has to pay (100-20) or 80%

The cost of the tablet is now 190 * .80

Then he has to pay 5% sales tax.

The tax is the prices times 5%   plus the original price

190 *.80 *(1+.05)

or 190 *.80 *(1.05)

Instead of adding the sales tax, he subtracted the sales tax.

The total he needs to pay is

190 *.80 *(1.05)

159.60

Hope this helps :)
