Answer:
2^12x3^5x5^5
Step-by-step explanation:
- The problem gives us the pieces of mail delivered per second and the amount of seconds in six days, so to find the pieces of mail delivered in six days we need to multiply pieces per second by seconds in six days.
-The pieces of mail delivered per second is 2^4x3x5^3, and seconds in six days is 2^8x3^4x5^2, therefore we must multiply (2^4x3x5^3)x(2^8x3^4x5^2)
-When multiplying powers with the same base, you need to add the exponent, for example 2^4 has the same base as 2^8, so when multiplying 2^4 and 2^8, we would have a product of 2^12
-Repeat this process with the remaining powers:
-3x3^4=3^5
-5^3x5^2=5^5
-Write the expression with the three powers
2^12x3^5x5^5

Option A
The radius of circle is 19.90 cm
<h3><u>
Solution:</u></h3>
The formula for circumference of circle is given as:
Where,
"C" is the circumference of circle
"r" is the radius of circle
is a constant equal to 3.14
Given that, circumference = 125 cm
To find: Radius of circle
<em><u>Substitute the given value of "C" = 125 in formula</u></em>
Thus radius of circle is 19.90 cm
Answer:
look at explanation (I go down the first column of scenarios and then move on to the right column)
Step-by-step explanation:
1) The first one will be same as original because the decrease and increase are the same, and happen right after each other so you get the same amount
2) Second one you get greater than original. You're doubling the initial value, and then decreasing by a smaller percentage, so you still get greater than your initial value
3) Third you get greater than original. You're adding 50% of the initial value, and decreasing by 33.5% of the new value, which will still give you more than the original
4) Fourth, you get greater than original. You're adding 60% of the initial value, and then decreasing by 40% of the new value, which will still give you greater than the initial value
5) Fifth you get less than the original. You're decreasing by 75%, and then adding 50% of the new value, which still gives you less than the initial value
Y = -2x -5
why?
-2x is found since in the table the x value is 0 and the y = -2
-5 because you are adding -5 every time
0= -2
-1 = -7
-2 = -12
-3 = -17
