The length of a tarpaulin is 3ft. more than thrice its width and its area is 126ft². What is the length of the tarpaulin?
Answer:
Length = 22 ft
Width = 6 ft
Step-by-step explanation:
Let the width of the tarpaulin be x meters.
Therefore, length = 3x + 3
Area of tarpaulin = 126 ft²
[tex]x(3x + 3) = 126 \\ \\ 3x(x + 1) = 126 \\ \\ {x}^{2} + x = \frac{126}{3} \\ \\ {x}^{2} + x = 42 \\ \\ {x}^{2} + x - 42 = 0 \\ \\ {x}^{2} + 7x - 6x - 42 = 0 \\ \\ x(x + 7) - 6( {x + 7)} = 0 \\ \\ (x + 7)(x - 6) = 0 \\ \\ x + 7 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 7 \: \: or \: \: x = 6 \\ \\ \because \: x \: is \: side \: length \\ \therefore \: it \: can \: not \: be \: negative \\ \implies \: x \notin - 7 \\ \\ \implies \: x = 6 \\ \\ 3x + 3 = 3 \times 6 + 3 \\ \\ 3x + 3 = 18 + 3 \\ \\ 3x + 3 = 21 \\ \\ length \: of \:the \: tarpaulin \: = 21 \: ft \\ \\ width \: of \: the\: tarpaulin \: = 6 \: ft \\ [/tex]

4/25
Step-by-step explanation:
Put the numbers where the letters are and do the arithmetic.
[tex]\left(2\cdot\dfrac{-1}{2}\cdot\dfrac{2}{5}\right)^2=\left(\dfrac{-2}{5}\right)^2=\dfrac{(-2)^2}{5^2}=\boxed{\dfrac{4}{25}}[/tex]
The Newtown Telephone Company advertises that if you use their 10-10 service, you will always pay only 9c per minute, no matter where you call within the country. Its major rival, Tryus Telephone Company, charges only 3c per minute, but you must pay a 36 c "connection fee" per call.
Create a cost equation for each telephone company where y is the total cost for each phone call (in cents), and x is the number of minutes the phone call lasts. Write a system of equations.
Answer:
y = 9x cents
y = (36 + 3x) cents
Step-by-step explanation:
Given that:
Newtown telephone company :
Fee per minute = 9c
Tyrus company :
Fee per minute = 3c
Connection fee = 36c
Cost equation :
y = total cost for each phone call:
x = minutes phone call last ;
Newton Company :
y = (fee per minute * minute phone call last)
y = 9 * x
y = 9x cents
Tyrus Company:
y = (connection fee + (fee per minute * minute phone call last))
y = (36 + (3 * x))
y = (36 + 3x) cents

Answer: x = -1
Step-by-step explanation: Insert all the numbers into x, and when you insert -1 to x, you get 40.
Answer:
x = - 1
Step-by-step explanation:
Given
- 4(3x - 7) = 40 ( divide both sides by - 4 )
3x - 7 = - 10 ( add 7 to both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
The cost of filling up Jason's car is directly proportional to the number of gallons purchased. It if costs Jason $32.40 to purchase 15 gallons of gas, find the cost of purchasing 20 gallons of gas.
Answer:
$43.2
Step-by-step explanation:
32.4÷15=2.16
2.16×20=43.2
The cost of purchasing 20 gallons of gas will be $43.2.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The costs Jason $32.40 to purchase 15 gallons of gas.
Now,
Let the cost of purchasing 20 gallons of gas = x
Since, The costs Jason $32.40 to purchase 15 gallons of gas.
So, By definition of proportion we get;
⇒ $32.40/15 = x / 20
⇒ 32.40 × 20 / 15 = x
⇒ x = $43.2
Thus, The cost of purchasing 20 gallons of gas = $43.2

Tyler has a bag that contains orange chews, cherry chews, and peach chews. He performs an experiment. Tyler randomly removes a chew from the bag, records the result, and returns the chew to the bag. Tyler performs the experiment 38 times. The results are shown below:
A orange chew was selected 28 times.
A cherry chew was selected 7 times.
A peach chew was selected 3 times.
Based on these results, express the probability that the next chew Tyler removes from the bag will be peach chew as a percent to the nearest whole number.
Answer:
8%
Step-by-step explanation:
Mathematically, the probability of an event can be obtained by dividing the expected number in which event will turn up divided by the total number we have in the sample space
From the question, the total number of times in which the experiment is performed is 38 times
The number of times we have the peach chew selected is 3 times
So the probability that the next removal will be a peach chew will be;
3/38 = 0.079
This as a percent is 7.9%
To the nearest whole number, this figure is 8%

If the given points in the table lie on a line, then the slope of a line is, 4
What is slope?Slope is a ratio of change in y-coordinate w.r.t. change in x-coordinate. The net change in y coordinate is written as, Δy and the net change in x coordinate is written as, Δx.
So formula for the slope is,
m = change in y coordinate/change in x coordinate = Δy/Δx
Given that,
Coordinates of a point through which line is passing,
X: 1 3 5 7
Y: 2 10 18 26
The slope of a line = ?
The slope of a line can be calculated by finding the rise (difference in the y-values) over the run (difference in the x-values) between two points on the line.
Now, Using the first and last points in the table:
First point- (1, 2)
Second Point- (7, 26)
Slope = (y₂ - y₁)/(x₂ - x₁)
Slope = (26 - 2) / (7 - 1)
= 24 / 6
= 4
The slope of the line is 4.
