(3 x 10^6) x (3 x 10^ 5)
OleMash [197]

Answer:

9*10^{11}

Step-by-step explanation:

we have

(3*10^{6})*(3*10^{5})

we know that

(a*10^{b})*(a*10^{c})=(a*a)*10^{(b+c)} -----> the bases are multiplied and the exponents are added up

so

in this problem

(3*10^{6})*(3*10^{5})=(3*3)*10^{(6+5)}

=9*10^{11}

Solve for x. Round to the nearest tenth, if necessary.
natka813 [3]

Answer:

25.5

Step-by-step explanation:

first find angle E.

remember, all angles in a triangle always add up to 180 degrees.

E = 180 - 90 - 20 = 70 degrees

now we use the law of sines.

ED/sin(20) = DC/sin(70) = EC/sin(D)

EC = x

sin(D) = sin(90) = 1

24/sin(70) = x/1 = x

x = 25.5
