What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.
here, we have,
given that,
At 12 p.m., the number of cars in a parking lot is 67.
It is estimated that the number of cars in the parking lot will decrease by 8% each hour.
so, we get,
Given,
at first the number of cars in a parking lot is = 67
now, it is decreasing by 8% each hour.
So, for any hours , let after 'n' hours,
the number will be = 67 * (100 - 8)%×n
=67 * 92%×n
= 67* 0.92n
Thus, The solution is, the formula found in the given question is ,

Find the area of the figure.
7 cm
8 cm
11 cm
The area is
square centimeters.
Answer:
let's divide the figure in rectangle and triangle.
first we should find the area of triangle.
area of triangle =1/2×base×height
area of triangle=1/2×11cm×7cm
area of triangle=38.5cm²
area of rectangle =length ×width
area of rectangle =11cm×8cm
area of rectangle =88cm²
area of the figure=38.5cm²+88cm²
area of the figure=126.5cm²
Write an explicit and a cursive equation for the geometric sequence
a. 2, 10, 50, 250, 1250, . . .
Answer:
Step-by-step explanation:
Explicit
a_n = a1 * r^(n - 1)
Find r by dividing term (n)/(n - 1)
r = 250 / 50
r = 5
a_n = a * r^(n - 1)
Recursive
a_n = a_(n-1)*r
Try an example
Find a_6
a_6 = 2 * 5^(6 - 1)
a_6 = 2 * 5^5
a_6 = 2 * 3125
a_6 = 6250
recursive
a_n = a_(n - 1)*r
r = 5
n = 6
a_n = 1250 * 5
a_n = 6250
The explicit method looks a whole lot easier, but not for a machine made by Dell and programed by Microsoft. A computer doesn't really mind doing a whole lot of calculations that are repetitive. And in many cases recursive is easier to program and is faster.
Answer:
explicit: a(n) = 2·5^(n-1)recursive: a(1) = 2; a(n) = a(n-1)×5Step-by-step explanation:
The given sequence is exponential with a first term of a1 = 2 and a common ratio of r = 10/2 = 5.
The explicit equation for an exponential sequence is ...
a(n) = a(1)×r^(n -1)
So, for the given parameters, the explicit equation is ...
a(n) = 2×5^(n -1)
__
The recursive equation for any series defines the next term as a function of previous terms. For a geometric sequence the next term is the previous term multiplied by the common ratio. For this sequence, the recursive definition is ...
a(1) = 2
a(n) = 5×a(n-1)

If two angles of a triangle are 75° and 40°, how many degrees is the third angle
Answer:65°
Step-by-step explanation:40+75+x=108X=65Solve the equation. Show the process, not just an answer. 6.EE.7
1) 4k = 24
2) 34 + h = 60
3) 1/5x = 30
4) m-42 = 85
Isolate the variable, note the equal sign, what you do to one side, you do to the other.
1) 4k = 24
Isolate the variable, k. Divide 4 from both sides of the equation:
(4k)/4 = (24)/4
k = 24/4
k = 6
2) 34 + h = 60
Isolate the variable, h. Subtract 34 from both sides of the equation:
34 (-34) + h = 60 (-34)
h = 60 - 34
h = 26
3) 1/5x = 30
Isolate the variable, x. Multiply 5 to both sides of the equation:
(5) * (1/5)x = (30) * (5)
x = 30 * 5
x = 150
4) m - 42 = 85
Isolate the variable, m. Add 42 to both sides of the equation:
m- 42 (+42) = 85 (+42)
m = 85 + 42
m = 127

Answer:
a[n] = (-1/3)^(n -1)
Step-by-step explanation:
The terms have a common ratio of (-1/3)/(1) = -1/3. The general term for a geometric sequence with first term a1 and common ratio r is ...
a[n] = a[1]×r^(n-1)
Here, a[1] = 1, so this is ...
a[n] = (-1/3)^(n-1)

A woman wishes to rent a house within 9 miles of her work. If she lives x miles from her work, her transportation cost will be cx dollars per year, while her rent will be 4c/( x + 1) dollars per year, where c is a constant taking various situational factors into account. How far should she live from work to minimize her combined expenses for rent and transportation? Use the methods outlined in this section to find the minimum.
Answer:
the woman has to live 1 mile from work to minimize the expenses
Step-by-step explanation:
Given the data in the question;
the distance within 9 miles ⇒ 0 < x > 9
Total costs Q = cx + 4c/( x + 1)
costs should be minimum ⇒ dQ/dx = 0
⇒ d/dx [ cx + 4c/( x + 1) ] = 0
⇒ ( x + 1)² = 4
take square root of both side
√[ ( x + 1)² ] = √4
x + 1 = 2
x = 2 - 1
x = 1
Therefore, the woman has to live 1 mile from work to minimize the expenses

What side length did Mr.Freeman measure the second time?
Answer: D) 2.33 meters
==========================================================
Explanation:
The hundredths digit is 1/10 of the tenths digit. Because of this, the tenths and hundredths digit must be the same digit.
Only choice D fits the description.
The digit in the tenths place represents the value 0.3
Taking 1/10th of this leads to (1/10)*0.3 = 0.1*0.3 = 0.03
So the hundredths place represents the value 0.03
Note that,
2 + 0.3 + 0.03 = 2.33 meters
