Actually, DIEDERICK drove faster than BROOK. What you can do to find out the answer, is divide. Brook drove 180 miles in 3 hours, so divide 180 by 3, and you get 60. If you divide 160 by 4, you get 40. So, that means that Diederick drove faster than Brook.

Percent decrease : (original number - new number) / original number..*100
= (225,000 - 191,250) / 225,000.....* 100

What is the surface area of a square pyramid with a slant height of 6cm and the length of one side of the square base is 5cm

erica [24]

Answer:

S = 85cm^2

Step-by-step explanation:

The surface area of a square pyramid is given by the following formula:

$S=2hb+b^2$

where it has taken into account the sum of the area of a square and four triangles:

$4(\frac{hb}{2})+b*b=2bh+b^2$

h: slant height = 6cm

b: base = 5cm

By replacing in the formula you obtain:

$S=2(5cm)(6cm)+(5cm)^2=85cm^2$

hence, the surface area is 85cm^2
