Answer:
129
Step-by-step explanation:
Each day, Monica measures the amount of change in the number of bacteria and this number from each day gives a geometric series
3, -6, 12, -24, ...... having first term 3 and the common ratio -2.
Then the sum of the amount of change in the bacteria after the seventh day will be ( 3 - 6 + 12 - 24 + 48 - 96 + 192) = 129 (Answer)
Answer:
50 packs of seed
Step-by-step explanation:
The back yard is a rectangle
Length is 28 ft
Width is 25 ft
The area of a rectangle is equal to the length times the width
area = length * width
So plugging in our numbers
area = 28 ft * 25 ft
area = 700 sqft
sqft means square feet or ft^2
We know each pack of seeds will cover 14 sqft, so the question is, how many times does 14 go into 700?
number of packs = 700 sqft / 14 sqft per pack
number of packs = 50 packs

we know that
Quotient is the number resulting from the division of one quantity by another
Let
x--------> the first quantity
y------> the second quantity
q------> the quotient
So
-------> equation 1
in this problem
Substitute the values in the equation 1
Simplify
therefore
<u>the answer is</u>
The quotient is equal to
