Answer:
(6x + 2) feet
Step-by-step explanation:
The formula for the perimeter of a rectangle = 2L + 2 W
Where L = Length
W = Width
Hence, the:
The length of the pool was (2x -3) feet and the width of the pool was (x + 4) feet.
The perimeter of the rectangular pool =
2(2x - 3) + 2(x + 4)
= 4x - 6 + 2x + 8
= 4x + 2x - 6 + 8
= (6x + 2) feet
Therefore, an expression for the perimeter of the pool area to be fenced is (6x + 2) feet

The difference btwn increasing a number by 20% and decreasing the same number by15% is 14 what is the number?
Answer:
The number is:
[tex]n = 40[/tex]Step-by-step explanation:
Let 'n' be the number
Increasing a number by 20% = (n + n×20/100)Decreasing a number by 14% = (n - n×15/100)As the difference between increasing a number by 20% and decreasing the same number by15% is 14.
Thus, the expression becomes
[tex]\left(n\:+\:\frac{n}{5}\right)\:-\:\left(n\:-\:\frac{3n}{20}\right)\:=\:14[/tex]
[tex]n+\frac{n}{5}-n+\frac{3n}{20}=14[/tex]
[tex]\frac{7n}{20}=14[/tex]
Multiply both sides by 20
[tex]\frac{7n}{20}\cdot \:20=14\cdot \:20[/tex]
[tex]7n=280[/tex]
Divide both sides by 7
[tex]\frac{7n}{7}=\frac{280}{7}[/tex]
[tex]n=40[/tex]
Thus the number is:

John is buying food for his cat, Fluffy. Fluffy LOVES a fancy wet food which costs $1.50 per day. Fluffy will also tolerate dry food which is $0.75 per day. John wants to spend at most $9.00 on cat food each week
Answer:
The answer is below
Step-by-step explanation:
Let x represent the number of days that fluffy eats wet food in a week and y represents the number of days that fluffy eats dry food in a week.
Hence:
x + y = 7 (1)
Also, John wants to spend at most $9.00 on cat food each week. Hence:
1.5x + 0.75y ≤ 9 (2)
The list of possible points after solving graphically are:
(0,7), (6,0), (0,12) and (5, 2). If x,y > 0, then the point that satisfies the inequality is:
(5, 2) i.e. 5 wet food and 2 dry food
You are planning a thanksgiving fest for all your family and friends. You invite 224 people. You plan to have a piece of pie for each guest. Pumpkin pies have 6 pieces and cost $5. Apple pies have 8 pieces and cost $7. You only have $191 left in your budget. How many of each type of pie should you hut
Answer:
Step-by-step explanation:
You are planning a thanksgiving fest for all your family and friends. You invite 224 people. You plan to have a piece of pie for each guest. You only have $191 left in your budget. How many of each type of pie should you hut
Let the number of pumpkin pies = p
The number of apple pies = a
Pumpkin pies have 6 pieces and cost $5. Apple pies have 8 pieces and cost $7.
Hence:
p + a = 224 people
p = 224 - a
$5 × p + $7 × a = $191
5p + 7a = 191..... Equation 1
Substitute 224 - a for p in Equation 1
5(224 - a) + 7a = 191
1120 - 5a + 7a = 191
- 5a + 7a = 191

Find the value of x that makes m || n
Answer:
a) 24
Step-by-step explanation:
To make m//n, the sum of co-interior angles (4x + 84) should be 180
4x + 84 = 180
4x = 180 - 84
4x = 96
x = 96/4
x = 24

Answer:
0=3/8
1=1 5/8
2= 4/2
i think?
Step-by-step explanation:
3/8 is less than a whole so it is 0
1 5/8 and 4/2 is 2 if simplified and 1 5/8 is less than 2 so 1 5/8 is 1 and 4/2 is 2

Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos CBA = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{3}{9}[/tex] , thus
∠ CBA = [tex]cos^{-1}[/tex] ([tex]\frac{3}{9}[/tex] ) ≈ 70.53° ( to 2 dec. places )
what is 31 billion in scientific notation?
explain clearly <3 :D
Answer:
3.1*10^10
Step-by-step explanation:
31 billion would be written like that because... there are 9 0's left, and that goes up to 10 because i turned 31 to 3.1 not 31, so that value after a decimal point adds 1

Help!!!! I will give brainliest.
Answer:
Step-by-step explanation:
Well lets try to simplify this.
-3y= -4x +17
y=4/3 x - 17/3
Thus y-int is (0, -17/3)
To solve for x-int, y=0
y=4/3 x - 17/3
0=4/3 x - 17/3
4/3 x = 17/3
x=17/4
Thus x-int is (17/4, 0)

The money m (in £) Paul has to spend each week is his wage w (in £) subtract the tax t (in £) he pays on his income. Enter a formula for the money he can spend and enter how much he has to spend if he earns £160 a week and pays £38 in tax.
Answer:
m = £122
Step-by-step explanation:
m = w - t
Where,
m = money Paul had to spend each week (£)
w = Paul's wage (£)
t = tax paid on his income (£)
If w = £160 and t = £38
Find m
m = w - t
= £160 - £38
= £122
Paul has £122 to spend if he earns £160 a week and pays £38 in tax

PLEASE HELP HELP!!! PRECALC
Answer:
The base is 0.1
The base is less than 1 so the function is decreasing
The x intercept is (3,0)
Step-by-step explanation:
The base of a logarithm refers to the number that must be raised to the power of the number on the right hand side of the logarithmic equation in order to yield the number on the left hand side of the logarithmic equation. It is always written as a subscript below the log symbol. In this case, the base is 0.1.
When the base of a logarithm is less than 1, it means that the function is decreasing as is the case in this question.
Looking at the graph, the x axis is cut at the point (3,0). This is the x-intercept of the graph.

Luis charges a travel fee of $10 plus $25 per month to mow his neighbors' lawns. If most of his customers only get their lawns mowed for 5 to 8 months out of the year, what is the RANGE of this situation?
Answer:
135 to 210
Step-by-step explanation:
Given
[tex]Base\ Charge = 10[/tex]
[tex]Additional\ Charge = 25[/tex] monthly
Months = 5 to 8
Required
Determine the range of the function
First, we need to determine the function equation.
Let total charges be y and months be x
[tex]y = Base\ Charge + Additional\ Charge * x[/tex]
[tex]y = 10 + 25 * x[/tex]
[tex]y = 10 + 25x[/tex]
When x = 5:
[tex]y = 10 + 25 * 5[/tex]
[tex]y = 10 + 125[/tex]
[tex]y = 135[/tex]
When x = 8
[tex]y = 10 + 25 * 8[/tex]
[tex]y = 10 + 200[/tex]
[tex]y = 210[/tex]
Hence, the range is 135 to 210
