Answer:
22. 10^10
8 Billion has 9 zeros and 10 to the power 10 means there is a total of 10 zeros. So 10 zeros is more closer to 9 zeros than that of 11 zeros.
23.Exponential form is when a certain number is raised to the power of a certain number or also known as exponents. Exponents signifies that the base or the number that is being raised to a certain powers will be multiplied a number of times, based on the exponents.
Exponential form is defined as repeated multiplication of the base.
If its an even number its divisible by 2 if you add the answer (7+8) and it equals a number (7+8=15) divisible by 3 then 78 is divisible by 3 and if it is divisible by both 2 and 3 then you know it is divisible by 6 but you have to be able to divide the number by BOTH 2 AND 3
well ik the angle of 1 and 2 are right angles and number 4 is 180° but I'm not sure ab number 2 sorry i.d.k if I helped someone might be able to explain better and help
<u>Answer</u>
B. Length = 37, width = 28
<u>Explanation</u>
Let the length of the rectangle be x,
width is 9 less. So, width = x - 9
Perimeter of a rectangle = 2(length + width)
2(length + width) = 130
2(x + x - 9) = 130
2(2x - 9) = 130
4x - 18 = 130
4x = 130 + 18
4x = 148
x = 148/4
= 37
<em>Length = 37</em>
<em>Width = 37 - 9 = 28</em>
