He needs to earn ; 77.99-20= 57.99 dollars

so in one week there are 2 weekends; so he earns 6×3×2 = 36 dollars

so no of week = 57.99÷ 36= 1.6 weeks

so weeks are in natural no thus it will take him 2 weeks !!

4 weeks because he earns 18 dollars per weekend so 18 multiplied by 4 plus 20 is 92 which gives him enough to get the new skateboard and the reason why it’s not 3 is because 3 multiplied by 18 plus 20 is not enough for the skateboard

What is 144 in exponential form? A) 212 B) 27 C) 43 D) 122

Alexandra [31]

Answer:

12²

Step-by-step explanation:

Given in the question, an integer = 144

To find the exponential form 144 we will do factorisation

The prime factorisation of 144 is

2 × 2 × 2 × 2 × 3 × 3

So the exponential form is 2 $^{4}$ × 3²

The other way is

√144 = 12

which means

12² = 144

Use braces and digits to indicate the set of whole numbers

Sergeeva-Olga [200]

Whole numbers are numbers without decimal points greater than 0.

The set of whole numbers is:

$W =\{0,1,2,3,4.....\}$

In the introductory part of this solution, I stated that:

Whole numbers do not have decimal point
The smallest whole number is 0

This means that the following numbers are whole numbers:

1, 9, 10, 67

While the following numbers are not:

-1, 9.0, 1.0, -67

Let W be the set of whole numbers; the set is:

$W =\{0,1,2,3,4.....\}$

The dots after 4 means the set still continues
