It's answer will be 36x10^5 As we have (4x10^10)(9x10^-5) All terms of this expression are being multiplied So we will solve it in two parts, simple terms and terms having powers (4x9)(10^10x10^-5) As we know when same terms having some powers are multiplied, their powers are added (36)(10^(10-5)) (36)(10^5) So it will become 36x10^5

Find the area of a triangle whose sides are 3cm,6cm and 7cm

nadya68 [22]

Answer:

See below

Step-by-step explanation:

It is NOT a RIGHT triangle so you <u>cannot use</u> 1/2 b * h

but you can use Heron's Formula

Area = sqrt( s (s-a)(s-b)(s-c) )

s = semi- perimeter = (3+6+7)/2 = 8

Area = sqrt ( 8 ( 8-3)(8-6)(8-7) ) = sqrt ( 80) = 8.9 cm^2

lakkis [162]

Answer:

The answer to your question is 757.1 cm²

Step-by-step explanation:

Data

Ratio 1: 1.618

long side = 35 cm

Area = ?

Process

1.- Use proportions to solve this problem

1 : 1.618 :: x : 35

x = (35 x 1) / 1.618

x = 35 / 1.618

x = 21.63

2.- Calculate the area of the rectangle

Area = base x height

Area = 35 x 21.63

Area = 757.1 cm²
