By applying basic concepts of powers of numbers we got that 9\times10^{-5} is equal to 0.00009

<h3>What is power?</h3>

The power of a number says how many times to use the number in a multiplication

Here given number is

9\times10^{-5}

We can write it as

\frac{9}{10^5}

We know that

10^5=100000

Hence we can write given number as

\frac{9}{100000}

And now after dividing we write it as

0.00009

By applying basic concepts of powers of numbers we got that 9\times10^{-5} is equal to 0.00009

What is the difference between greatest common divisor and greatest common denominator ?
il63 [147K]

The greatest common factor (GCF) of a set of numbers is the largest factor that all the numbers share. For example, 12, 20, and 24 have two common factors: 2 and 4. The largest is 4, so we say that the GCF of 12, 20, and 24 is 4. GCF is often used to find common denominators

We will use Pythagorean Theorem:
HC^2=20^2-12^2=400-144=256
HC=\sqrt{256}=16
HD^2=16^2-14^2=256-196=60
HD=\sqrt{60}=7.7459
Answer: HD=7.7 in.

The population of a local species of dragonfly can be found using an infinite geometric series where a1 = 42 and the common rati
Mashutka [201]

we are given

first term is

a_1=42

common ratio is

r=\frac{3}{4}

now, we can find nth term

a_i=a_1(r)^{i-1}

now, we can plug values

a_i=42(\frac{3}{4})^{i-1}

now, we can write in sigma form

sum=\sum _{i=1}^{\infty }\:42(\frac{3}{4})^{i-1}

now, we can find sum

we can use formula

sum=\frac{a}{1-r}

now, we can plug values

we get

sum=\frac{42}{1-\frac{3}{4}}

sum=168

so, option-D.................Answer

A sporting goods store is having a 40% off sale. What would be the sale price for a pair of skis that originally cost $108.
Rzqust [24]

Answer:

$64.80

Step-by-step explanation:

Instead of saying 40% off, I look at is as paying 60% on.  (100% less 40%). So I’m going to pay 60% of the original price of $108.  

60% of $108 is $64.80
