Kelly has a pool in her backyard, and she wants to build a fence around the entire area. Kelly's backyard is 14 meters wide and 15 meters long. It costs $6.63 per meter to install a wooden fence. How much would it cost to put a wooden fence around Kelly's backyard?
Answer:
$384.54Step-by-step explanation:
Dimensions of the backyard is 14 m by 15 m
The length of the fence is the perimeter of the backyard.
P = 2(l +w)P = 2(15 + 14) = 2(29) = 58 mOne meter of the fence costs $6.63
Cost of the entire fence is:
58*$6.63 = $384.54Answer:
perimeter of backyard=2(15+14)=58m
it cost
1m=$6.63
58m=$6.63×58=$384.54
therefore it cost
$384.54 to put a wooden fence around Kelly's backyard.
On average, a refrigerator door is opened 22 times each day. Len has two refrigerators in his house. Based on this average, about how many times in a 9−week period are the refrigerator doors opened?
Answer:
2772 times
Step-by-step explanation:
On average, a refrigerator door is opened 22 times each day.
Len has two refrigerators in his house.
Step 1
From the above question:
1 refrigerator = 22 times
2 refrigerators = 2 × 22 times
= 44 times.
Hence, Per days 2 refrigerators is opened 44 times
Step 2
In 1 week = 7 days =(For 2 refrigerators)
1 day = 44 times
7 days = x times
x = 7 × 44
x = 308 times.
Hence in 1 week, the 2 refrigerators are opened 308 times
Step 3
How many times in a 9−week period are the refrigerator doors opened
1 week period = 308 times
9 week period =
308 times × 9
= 2772 times

A typical ID number in a college class consists of a four-digit number, such as 0119. When an ID number is randomly selected, what is the probability that no two of its digits are the same
Answer:
[tex]Probability = 0.504[/tex]
Step-by-step explanation:
Given
[tex]ID: 4\ digit\ number[/tex]
Required
Determine the probability that no two digit is repeated
First, we need to determine the total possible number of pins (with repetition)
Each of the 4 ID digit can be selected from any of the 10 digits (0 - 9).
i.e.
[tex]First = 10[/tex]
[tex]Second = 10[/tex]
[tex]Third = 10[/tex]
[tex]Fourth = 10[/tex]
[tex]Total = 10 * 10 * 10 * 10[/tex]
[tex]Total = 10000[/tex]
i.e.
[tex]n(Repetition) = 10000[/tex]
Next, we determine the total possible number of pins (without repetition)
Once a digit is selected from any of the 10 digits (0 - 9), it can no longer be repeated.
i.e.
[tex]First = 10[/tex]
[tex]Second = 10 - 1 = 9[/tex]
[tex]Third = 10 - 1 - 1= 8[/tex]
[tex]Fourth = 10 - 1 - 1 - 1 = 7[/tex]
[tex]Total = 10 * 9 * 8 * 7[/tex]
[tex]Total = 5040[/tex]
i.e.
[tex]n(No\ Repetition) = 5040[/tex]
The probability is then calculated as:
[tex]Probability = \frac{n(No\ Repetition)}{n(Repetition)}[/tex]
[tex]Probability = \frac{5040}{10000}[/tex]
[tex]Probability = 0.504[/tex]
Tell whether the slope of the line is positive, negative, zero, or undefined
↝ In the graph, the slope is zero.
When the slope is positive. The line graph will head from third quadrant to first quadrant.
When slope is zero. The line graph will be like in the graph that's shown in this question's picture.
When slope is negative. The line graph will head from second quadrant to fourth quadrant.
The slope of the line shown in the given figure is 0 as the y is constant at every point on the line.
A slope of a straight line is the angle it makes with the x-axis. In a straight line of the form y = mx + c, the coefficient of x, m is the slope of the line and is given by the formula
[tex]m = \dfrac{y_2 -y_1}{x_2 - x_1}[/tex].
The equation of the line is y = 1.
Let's take any two points from the graph on the line.
Let's take points (0, 1) and (1, 1), then the slope of the line is given as
[tex]m = \dfrac{y_2 -y_1}{x_2 - x_1}[/tex]
[tex]= \dfrac{1 -1}{1-0} \\=\dfrac{0}{1}\\ =0[/tex]
Thus, the slope of the given line is 0.

: • 1:33)= 8 • x
7.998 = 8x
1 = x
•59x + 32 = 1.39x
32 = .8x
40 = x
Answer:
20 tiles
Step-by-step explanation:
If she buys 60 tiles, the cost at both shops is the same.
If she buys less than 60 tiles, then the second shop is cheaper.
If she buys more than 60 tiles, then the first shop is cheaper.
Explanation:
Let the number of tiles be
x
At the first shop: Cost = $0.59 × x + $14 = 0.59x + 14
At the second shop: Cost = $ 1.29 × x = 1.29x
If the cost is the same:
1.29x = 0.59x + 14 ←solve for x
1.29x − 0.59x = 14
0.7x = 14
x = 14/0.4
x = 20 tiles
$6,000 dollars is invested in two different accounts earning 3% and 5% interest. At the end of one year, the two accounts earned $220 in interest. Set up a systems of linear equations to model the amount of money invested and the interest earned.
Answer:
x + y = 6000
0.03x + 0.05y = 220
Step-by-step explanation:
Given that :
Total principal amount = $6000
Account A:
Let principal = x
Rate = 3% = 0.03
Account B:
Let principal = y
Rate = 5% = 0.05
Interest earned at after one year = $220
Amount invested :
x + y = 6000
Simple interest = principal x rate x time
Interest earned
(x * 0.03 * 1 ) + (y * 0.05 * 1) = $220
0.03x + 0.05y = 220

as x would be numbers going up for example y=2(1)+8. 2 times 1 is 2 plus 8 is 10 then u do 2. 2(2)+8 is 2 times 2 which is 4 plus 8 that is 12 and no other sequence is 10,12 so it is A
The expression (3 + i)(1+2i) can be written in the form a + bi, where a and b are integers. What are the values of a and b?
Answer:
a = 1 and b = -7
Step-by-step explanation:
Given the expression
(3 + i)(1+2i)
On factorizing we have;
(3 + i)(1+2i)
= 3(1)+3(2i)+1(i)+i(2i)
= 3 + 6i + i + 2i²
= 3 + 7i + 2i²
Since i² = -1
The expression becomes;
= 3 + 7i + 2(-1)
= 3 + 7i -2
= 1 - 7i
On comparing with a + bi
a = 1 and b = -7
Write your question here (Keep it simple and clear to get the best answer)4x³-5x is it odd or even function
Answer:
odd
Step-by-step explanation:
To determine if odd/ even
• If f(x) = f(- x) then it is even
• If f(- x) = - f(x) then it is odd
Given
f(x) = 4x³ - 5x , then
f(- x) = 4(- x)³ - 5(- x) = - 4x³ + 5x
Since f(x) ≠ f(- x) then it is not even
- f(x) = - (4x³ - 5x) = - 4x³ + 5x
Since f(- x) = - f(x) , then 4x³ - 5x is odd

Jace is making a water play table from a triangular table top. He sketched a dotted line to show where he wants to add a circular water bowl. It should go all the way to the edges of the table as shown. A circle is inscribed within triangle A B C. The length of A B is 3.5 feet, the length of B C is 4 feet, and the length of A C is 2 feet. Angle A B C is 30 degrees and angle A C B is 60 degrees. What should Jace do first to find the exact location of the center of the circular water bowl? He should find the midpoint of each edge of the table. He should bisect each of the angles at the vertices of the triangular table top. He should draw perpendicular lines through any point along the edges of the table. He should draw perpendicular line segments from each corner to the opposite edge of the table.

Answer:
86 heartbeats per minute
Step-by-step explanation:
i assume that's your question?
the number of heartbeats per minute is 86.
What is the unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given that, 473 heartbeats in [tex]5\frac{1}{2}[/tex] = 11/2minutes
Number of heart beats per minute = Total number of heart beats ÷ Number of minutes
= 473÷ 11/2
= 473×2/11
= 43×2
= 86 beats per minute
Therefore, the number of heartbeats per minute is 86.
