Answer:
1138
Step-by-step explanation:
From the information given:
We can represent it perfectly in an exponential form:
where;
p = initial value = 120
q = base of the exponential form
q = 1 + r
here; r = rate in decimal = 10% = 0.1
Then q can now be = 1 + 0.1 = 1.1
Replacing it into the exponential form, we get:
where;
x = number of days and m = number of shoppers
Thus:
For the first day:
m = 120
For the second day:
m = 132
For the third day:
m = 145.2
For the fourth day
m = 159.72
For the fifth-day
m = 175.692
For the sixth-day
m = 193.2612
For the seventh-day
m = 212.58732
Thus; the total numbers of shoppers for the first 7 days is:
= 1138.46052
≅ 1138
Answer:
-3
Step-by-step explanation:
Numbers that come out of the absolute values are always positive.
|6 - 4| -|3 - 8| =
| 2| - | -5| =
2 - 5 =
-3
He put 3 in the bag because 12 divided by 4 is 3
No, it would be 180.0 , since you are multiplying the small amount by a large amount that is not negative.
Answer:
Width = 5
Length = 11
Step-by-step explanation:
Let :
Width, = x
Length = 2x + 1
Area of rectangular garden is given as 55 ft²
Area of a rectangular garden, A = Length * width
Hence,
x * (2x + 1) = 55
2x² + x = 55
2x² + x - 55 = 0
Using the quadratic equation formula :
a = 2 ; b = 1, c = - 55
-b ± sqrt(b² - 4ac) / 2a
Using the quadratic equation solver to save computation time :
The roots are :
-5.5 and 5
Dimension can't be negative ; so x = 5
Hence,
width, x = 5
Length, 2x + 1 = 2(5) + 1 = 10 + 1 = 11
Hence,
Width = 5
Length = 11
