Multiply (2*10^4)(3*10^3)

6.2* 10 ^-24

Step-by-step explanation:

(2.0 ⋅ 10−4) ⋅ (3.1 ⋅ 10−20)

Multiply the numbers

2.0 * 3.1 =6.2

Add the exponents

10 ^-4 * 10 ^-20 = 10 ^( -4+-20) = 10 ^ -24

Put back together

6.2* 10 ^-24

The number is in scientific notation since there is one nonzero digit in front of the decimalv

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
