Given dimensions of a rectangular garden are:
length = 2(x+6) feet
width = 3.5x feet
using the distributive property on length we get, length = 2x+12
Perimeter of a rectangle is 2(length+width)
So, P = 2(2x+12+3.5x)
Solving it we get,
P = 2(5.5x +12) ..............adding like terms
P = [tex](2\times5.5)+(2\times12)[/tex] .............multiplying and adding
P = 11x+24
So, perimeter is 11x+24 feet. This value of fencing will be needed.

Find the slope of a mountain that descends 100 meters for every horizontal distance of 1,000 meters.
We are given: a mountain descends (getting down vertically) = 100 meter.
For getting down we would take it by a negative number so it would be -100 meter.
And every horizontal distance = 1,000 meter.
We know formula for slope is = Change in vertical distance/ Change in Horizontal distance.
Plugging values in formula of slope above, we get
Slope = -100/1000 = -1/10 or -0.1.
Therefore, we could say the slope of a mountain is [tex]-\frac{1}{10}\ or \ -0.1.[/tex]

Solve for v in terms of s, t, an u. U=tsv
Final answer:
To solve for velocity v in the provided equation U=tsv, divide both sides by ts to isolate v, resulting in v = U / (ts).
Explanation:
Solving for v in Terms of s, t, and u:
To solve for v in terms of s, t, and u given the equation U=tsv, we can rearrange the equation to isolate v. We start by dividing both sides of the equation by ts, which results in:
v = U / (ts)
This equation shows that the velocity v can be calculated if we know the initial velocity u, the time t, and the displacement s.
Give one example of when you would make a frequency table to solve the problem
Answer:
Consider a class in which there are 40 students .There is a Mathematics test of 50 marks .Two students were absent.The Duration of test was for one and half an hour.
So Marks of students according to their roll number are 12,8,4,20,25,36,2,29,35,39,5,48,43,37,38,29,17,15,15,25,31,32,26,28,27,24,2,15,34,,50,46,48,37,28,26,45,49,24.
So in this case it would be better to prepare frequency polygon by selecting a class interval.
Class interval = 0-5,5-10,10-15,15-20,20-25,25-30,30-35,35-40,40-45,45-50.
Or 0-10,10-20,20-30,30-40,40-50.
or you can make class interval by yourself.
which graph shows the solution to the following inequality? 4d-6<18
Answer: C
Step-by-step explanation:
4d - 6 < 18
+6 +6
4d < 24
[tex]\frac{4d}{4} < \frac{24}{4}[/tex]
d < 6
Graph: ←----------------o 6
Answer:
option (c) is correct.
d < 6
On number line this is shown as attached below.
Step-by-step explanation:
Given inequality 4d - 6 < 18
We have to plot the inequality and check out of given graph which graph satisfies the Given inequality 4d - 6 < 18
Consider the given inequality 4d - 6 < 18
Add 6 both sides, we have,
4d - 6 + 6 < 18 + 6
Simplify we get,
4d < 24
Now, divide both side by 4, we have,
[tex]\frac{4d}{4}<\frac{24}{4}[/tex]
Simplify , we have,
d < 6
On number line this is shown as attached below.
Thus, option (c) is correct.
determine the tax if a flat tax of 15% is applied to an income of $400,000.
Hey there!
Let's start by simply finding 1% of $400,000.
To do this we can divide by 100, since 1% is the same thing as 1/100.
400,000 ÷ 100 = 4,000
Next, we can multiply 4,000 by 15, because 4,000 is 1% and we are looking for 15%.
4,000 x 15 = 60,000
This means the tax is $60,000.

patrick was born with 1\7 of his faults and acquired the rest during his teenage years. if he was born with 326 faults, how many does he have total?
Answer:
i think it is 2,282
Step-by-step explanation:
break it down 300 x 7 is 2,100 20 x 7 is 140 and 7 x6 is 42
addit together and you have your answer
Answer: 2282
Step-by-step explanation:
To get the answer, first we make an equation.
Lets use f for faults.
So we know that Patrick was born with 326 faults. He had 1/7 the number of faults he has now when he was born. The question is asking how many faults he has in total. Now we can set up our equation.
326 = 1/7f
326 is on the left of the equal sign because 326 is equal to 1/7 the number of faults he has now. Next, because 1/7 is 1 divided by 7, we multiply 1/7f by 7. We get 1f or f because there is only 1 f. But what we do to one side we must do to the other. So when we multiply 7 to 1/7f we also multiply 7 to 326. This is our answer:
2282 = f

Step-by-step explanation:
The legs of a right triangle measure 5 inches and 7 inches. If theta is the angle between the 7 inch leg and the hypotenuse, sin theta = ___
Answer:
sin (θ) = 0,58
Step-by-step explanation:
The formula for sin (θ) is:
sin (θ) = (opposite side)/hypotenuse
The opposite side to the θ angle is the one that measures 5 inches, but we don’t know the measure of the hypotenuse. The Pythagoras theorem gives us the following formula:
side 1²+ side 2²= hypotenuse²
Then,
5²+7²=74
√74= 8,60 inches; this is the measure for the hypotenuse.
Replacing this value in the formula for sine:
sin (θ) = 5/8,60 = 0,58
the height of a right cylinder is 3 times the radius of the base. The volume of the cylinder is 24 cubic units
Let the radius of the base be r units
Then the height will be 3r units
Volume of cylinder = pi r^2 h
24=pi r^2 × 3r
Pir^3 = 24/3
Pi r ^3 =8
r^3 = 8/pi
R = 2 / pi^1/3
Height = 6/pi^1/3

A patient in the emergency room is monitored for heart rate, oxygenation level, etc. The nurse notices that the heart beat averages 80 but drops to 60 beats every other minute and then spikes to 120. The cardiologists have asked the nurses to notify them if this happens, as that pattern is indicative of heart attacks. The nurse calls the doctor.
Is the nurse using inductive or deductive reasoning?

A rope is used to anchor a boat to the shore. The angle of depression from the boat to the water is 40° . The height of the boat above the water is 25.17 feet. What is the length of the rope that is anchoring the boat to the shore?
Final answer:
To find the length of the rope anchoring the boat to the shore, use the tangent function with the angle of depression and the height of the boat above the water.
Explanation:
To find the length of the rope anchoring the boat to the shore, we can use trigonometry. The angle of depression from the boat to the water is 40° and the height of the boat above the water is 25.17 feet. We can use the tangent function to find the length of the rope. tan(40°) = opposite/adjacent. The height of the boat above the water is the opposite side and the length of the rope is the adjacent side. So, we have:
tan(40°) = 25.17/adjacent
Solving for the adjacent side, we get:
adjacent = 25.17 / tan(40°)
Using a calculator, we can evaluate this expression to find that the length of the rope is approximately 33.95 feet.
