Answer:
22ftStep-by-step explanation:
Step one:
given that the orientation of the garden is a triangular shape(it has three sides)
the perimeter is given as=46ft
one side y=11ft
the second side z= 13ft
let the third side be xft
Step two:
the expression for the perimeter = z+y+x
46=11+13+x
46=24+x
solve for x
x=46-24
x=22ft
Therefore the third side is 22ft long
HURRY!! A climber is on a hike. After 2 hours he is at an altitude of 400 feet. After 6 hours he is at an altitude of 700 feet. What is the rate of change.
Answer:
175ft an hour
Step-by-step explanation: lets say t=hours
so 2t=400ft and 6t=700ft
the difference between hours is 4 because 6-4=2
so we would multiply 4 by ?
to get the missing # you would have to multiple 4 by numbers between 170 and 190 because anything under 170 is no where near 175 and anything above 190 is way off 175. Answer is 175ft per hour
Answer:
total distance =700+400ft
time =2+8 =10hour
rate =distance/time=1100/10=110 ft/hour
since he stops two times
rate of change =110/2=75ft/hour
2n – 32 = 10(n - 8) what is the answer
Answer:
n = 6
Step-by-step explanation:
2n - 32 = 10n - 80
2n - 10n = -80 + 32
-8n = -48
-48/-8 = 6
12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

The diagram shows ∆QRS. Which term describes point T?
A. circumcenter
B. Orthocenter
C. Incenter
D. Centroid
Answer:
Step-by-step explanation:
A
The term which describes the point T in triangle QRS is option A. Circumcenter.
Here, given is a triangle QRS.
It is clear that three lines are drawn and all the three lines intersect at the point T.
Each of the line is perpendicular to each of the sides of the triangle.
And each of the line bisects each of the sides, that is sides are being divided in to half.
So T is the intersecting point of all the perpendicular bisectors of the sides, which is the definition of circumcenter.
Thus, T is the circumcenter of the triangle QRS.

What does 100% increase mean
An increase of 100% in a quantity means that the final amount is 200% of the initial amount (100% of initial + 100% of increase = 200% of initial). In other words, the quantity has doubled. An increase of 800% means the final amount is 9 times the original (100% + 800% = 900% = 9 times as large).

If option A is 20 dollar payment and option B requires 50 dollar payment. The opportunity cost of option A would be ------- and option B would be --------. a) nothing and 30 dollars. b) 70 dollar and nothing c) 30 dollar and nothing
Answer:
a) nothing and 30 dollars.
Step-by-step explanation:
Opportunity cost usually arises when faced with choices or alternatives such that one has to be chosen, while the other is forgone. The benefits forgone by choosing a certain option of the available choices is called opportunity cost.
Given that :
Option A requires $20 payment
Option B requires $50 payment
Opportunity cost of choosing A = nothing (since payment required for the other alternative is higher than the chosen option)
Opportunity cost of Choosing B = ($50 - $20) = $30 (By choosing option B over option A, $30 was forgone as the other option (option A requires $30 lesser payment)
This equation shows how the length of Rob's essay depends on the number of hours he spends writing this week. p = h + 11 The variable h represents the number of hours he spends writing this week, and the variable p represents the total number of pages that have been written. How many hours will Rob have to spend writing this week in order to have written a total of 16 pages?
Answer:
Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.
Step-by-step explanation:
From the information given, you can use the formula p=h+11 and solve for h. Then, you have to replace p with 16 to get the amount of hours that Rob will have to spend writing this week in order to have written a total of 16 pages:
p=h+11
h=p-11
h=16-11
h=5
According to this, the answer is that Rob will have to spend 5 hours writing this week in order to have written a total of 16 pages.

The marked price of an article is 25% above the selling price and the cost price is 20% below the selling price. Find the rate of discount and the profit percentage.
Step-by-step explanation:
The marked price of an article is 25% above the SP and the CP is 20% below the selling price. What is the rate of discount and the profit percentage?
Let C, M & S denote cost-price, marked-price & sell-price respectively of the article.
Hence from above data we get following relations,
M = (1 + 25/100)*S = 1.25*S ….. (1a)
C = (1 - 20/100)*S = 0.80*S ….. (1b)
From (1a) we get,
S = (100/125)*M = (4/5)*M
or S = (1 - 1/5)*M = (1 - 20/100)*M ….. (2a)
From (1b) we get,
S = (100/80)*C = (5/4)*M
or S = (1 + 1/4)*C = (1 + 25/100)*C ….. (2b)
Therefore
It is evident from (2a) that
the discount percentage = 20% [Ans]
It is evident from (2b) that
the profit percentage = 25% [Ans]

2x+9=8x+21
Step 1: Subtract 8x from both sides.
2x+9−8x=8x+21−8x
−6x+9=21
Step 2: Subtract 9 from both sides.
−6x+9−9=21−9
−6x=12
Step 3: Divide both sides by -6.
-6x/-6=12/-6
x=-2
Answer:
-2 = x
Step-by-step explanation:
First, combine like-terms. I subtracted 21 from both sides and subtracted 2x from both sides. This gave us 12 = -6x. Then, divide to solve for x. This gives us -2 = x.

The rule R x-axis ∘ T⟨–5, 3⟩ is applied to the point (–3, –2). Where is the image in the coordinate system?
Given:
Rule of transformation is rule R x-axis ∘ T⟨–5, 3⟩.
The point is (-3,-2).
To find:
The image of given point after the transformation.
Solution:
Consider the given point be P(-3,-2).
Rule of transformation is rule R x-axis ∘ T⟨–5, 3⟩. If means first we have apply translation T⟨–5, 3⟩ after that we have to apply reflection R x-axis.
If a figure translated by T⟨–5, 3⟩, then
[tex](x,y)\to (x-5,y+3)[/tex]
[tex]P(-3,-2)\to P'(-3-5,-2+3)[/tex]
[tex]P(-3,-2)\to P'(-8,1)[/tex]
If a figure reflected by R x-axis, then
[tex](x,y)\to (x,-y)[/tex]
[tex]P'(-8,1)\to P''(-8,-1)[/tex]
Therefore, the image of given point after transformation is (-8,-1).
