A rocket travels 2.8x10^4 km h^-1. find how far it travels in 5 hours

mixas84 [53]

It is given in the question that, a rocket travels 2.8x10^4 km h^-1.

It means in one hour, the rocket travels

$2.8* 10^4km.$

And we have to find how much the rocket travels in 5 hours, and for that we have to do multiplication, that is

$2.8*10^4 *5 = 14*10^4 = 1.4* 10^5 km$

Find the sum of the following numbers without actually adding them1+3+5+7+9+11+13+15

Dovator [93]

S = 1 + 3 + 5 + ... + 11 + 13 + 15

S = 15 + 13 + 11 + ... + 5 + 3 + 1

==> 2S = (1 + 15) + (3 + 13) + (5 + 11) + ... + (15 + 1)

There are 8 terms in the sum, so

2S = 8 * 16 = 128

S = 128/2 = 64

mina [271]

Ms. Pacheco = P
Mr. Richards = R
Mr. Edwards = E
P = R + 3
E = 2R
R + E = 81
81 = R + 2R
81 = 3R
81 ÷ 3 = R
R = 27
P = R + 3
P = 27 + 3
P = 30
E = 2R
E = 2×27
E = 54
