Multiply (2.0 ⋅ 10−4) ⋅ (3.1 ⋅ 10−20). Express the answer in scientific notation. 6.2 ⋅ 10−80 6.2 ⋅ 10−24 6.2 ⋅ 1024 6.2 ⋅ 1080

Answers

scientifice notation is
(number less than 10 but greater than or equal to 1) times (10^x)

remember
(ab)(cd)=abcd=(ac)(bd)

and
(x^m)(x^n)=x^(m+n)

so
(2*10^4)(3.1*10^20)=
(2)(10^4)(3.1)(10^20)=
(2*3.1)(10^4*10^20)

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

(6.2)(10^24)

scientifie notiaotn is
6.2*10^24

Sally plans to run 12 miles. She ran 5 1/8 miles and then stopped for a water break. How many miles does Sakky have left to run?

Answers

So,

We can just subtract the fractions without converting any denominators. To do that, we can split the subtraction problem up as follows:

12 - 5 - 1/8
7 - 1/8
6 7/8

Sally still has 6 7/8 or 6.875 miles to run.

Write 120% as a fraction.

Answers

6/5 because each 1 equals 20%. so 1/5=20%, 2/5=40%, 3/5=60% and so 5/5=100% so 6/5=120%. hopefully that helps.

120% as a fraction in simplest form is 6/5.

What is a fraction?

In Mathematics and Geometry, a fraction simply refers to a numerical quantity (numeral) which is not expressed as a whole number. This ultimately implies that, a fraction is simply a part of a whole number.

In this exercise and scenario, we would convert the given percentage 120% into a fraction by dividing as follows;

120% = 120/100

By dividing both the numerator and denominator by 20, we have:

Fraction: 120/100 = 6/5.
