Express the number 0.00001038 in scientific notation

In-s [12.5K]

For this case it is observed that the "zeros" are to the left of the expression, therefore the exponent, to be expressed in scientific notation, will be negative. That is to say:

$10.38 * 10^ {- 6}$

This means that by running the decimal 6 spaces to the left we will get the initial expression.

ANswer:

$10.38 * 10^{ - 6}$

Machine A produces 75 fishing lures per minute. Machine B produces 50 of the same lure per minute. How long will it take both ma

geniusboy [140]

Machine A will take 28 minutes to produce 2100 fishing lures while machine B will take 42 minutes to produce 2100 fishing lures

Step-by-step explanation:

Fishing lures per minute produced by Machine A = 75

Fishing lures per minute produced by Machine B = 50

How long will it take both machines running to produce 2100 fishing lures?

Solving For Machine A:

75 fishing lures produced by machine A = 1 minute

1 fishing lures produced by machine A = 1/75 minute

2100 fishing lures produced by machine A = 1/75*2100

= 28 minutes.

Solving For Machine B:

50 fishing lures produced by machine A = 1 minute

1 fishing lures produced by machine A = 1/50 minute

2100 fishing lures produced by machine A = 1/50*2100

= 42 minutes.

So, Machine A will take 28 minutes to produce 2100 fishing lures while machine B will take 42 minutes to produce 2100 fishing lures

Step-by-step explanation:

Loan in US$: 6,300

Term: One Year

Interest rate: 9.75% annually

1. Let's calculate how much money Deb will pay in interests for the loan:

Loan * Interest rate * Term

6,300 * 0.0975 * 1

614,25

Deb will have to pay US$ 614,25 in interests for the loan

2. Let's calculate how much money Deb will pay back at the end of the loan term

Loan in US$ + Interests in US$

6,300 + 614,25

6,914,25

At the end of the loan Deb will have to pay $ 6,914.25
