Kiesha and her classmates wrote proportions for the reduction of a triangle.
A larger and smaller triangle have corresponding heights and bases.
Which proportions are set up correctly? Select three options.
StartFraction original height over original base EndFraction = StartFraction reduction height over reduction base EndFraction
StartFraction original height over reduction height EndFraction = StartFraction original base over reduction base EndFraction
StartFraction original height over reduction base EndFraction = StartFraction reduction height over original base EndFraction
StartFraction reduction height over reduction base EndFraction = StartFraction original height over original base EndFraction
StartFraction original height over original base EndFraction = StartFraction reduction base over reduction height EndFraction
Answer: A, B, and D are correct!
Step-by-step explanation:
Hope this helps! :)
The three proportions that are set up correctly for the reduction of a triangle are:
original height / original base = reduction height / reduction base
original height / reduction height = original base / reduction base
original height / reduction base = reduction height / original base
Options 1, 2, and 3 are correct.
What is a triangle?A triangle is a 2-D figure with three sides and three angles.
The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
The three proportions that are set up correctly for the reduction of a triangle are:
1)
original height / original base = reduction height / reduction base
This proportion represents that the ratio of the original height to the original base is equal to the ratio of the reduction height to the reduction base.
2)
original height / reduction height = original base / reduction base
This proportion represents that the ratio of the original height to the reduction height is equal to the ratio of the original base to the reduction base.
3)
original height / reduction base = reduction height / original base
This proportion represents that the ratio of the original height to the reduction base is equal to the ratio of the reduction height to the original base.
Thus,
original height / original base = reduction height / reduction base
original height / reduction height = original base / reduction base
original height / reduction base = reduction height / original base

Find the value of Y, 14 points
Answer:should be 125°
Step-by-step explanationz, y, and x make a 180° line. 52+3=55 and subtracting that from the total 180°gives you 125
Answer:
y = 8
Step-by-step explanation:
1. subtract 52° from 180° to get the value of the obtuse angle
2. that leaves you with 128° and now you subtract from 180° again bc the angles of a triangle always add up to 180° and so you have 52° now
3. the two angles you dont have add up to 52° and from here you write the equation 3y + 4y - 4 = 52
4. combine like terms to simplify the equation so you have 7y - 4 = 52.
5. add 4 to both sides so you get 7y = 56 nd then divide both sides by 7 leaving you with y = 8
A train leaves the station at time = 0. Traveling at a constant speed, the train travels 330 kilometers in 3 hours. Answers parts a and b. A. Write a function that relates the distance traveled d to time t. The function that relates the distance traveled d to the time is.
Answer:
The function that relates the distance traveled d to the time t is
f(t) = 110t, where d = f(t)
Step-by-step explanation:
From the question, we were told that the train is At a constant speed, the train travels 330 kilometers in 3 hours
We were told to write function that relates the distance traveled d to the time t, we can do this by writing a linear equation with those functions
Since we are told that the train travels 330 kilometers in 3 hours, then we can say the train travel (330/3) kilometers in 1 hour which means it travel 110 kilometers in 1 hour
Then d= 110t---------------eqn(1)
If if t = 0, then d = 0, as well since at t=0 the train is at the station
At t = 1 then d = 110.
From equation (1) d can be replaced by f(t) then we have
f(t) = 110t----------------eqn(2)
Now we replace d by f (t), because d = f t):
f(t) = 120t
Therefore, The function that relates the distance traveled d to the time is f(t) = 120t

Cory is a bird watcher he estimates that 30% of the birds he sees are american robins, 20% are dark eyed juncos and 20% are slnc sparrows. he designs a simulation.
Answer:
I think C. 0.75
Step-by-step explanation:
The probability of seeing at least one robin in the next 5 birds is 0.75
How to determine the probability?The representations are given as:
American robins = 0 to 2Dark eye juncos = 3 and 4Song sparrows = 5 and 6Others = 7 to 9Using the above representations, the numbers that represent an occurrence of seeing at least one robin in the next 5 birds are:
05716 16803 32177 92290 72794 14333 79019 05943 77510 74051 87238 86481 94036 12749 24005
The number of occurrence is:
Number = 15
The number of simulation is 20
So, the probability of seeing at least one robin is:
P = 15/20
Divide
P = 0.75
Hence, the probability of seeing at least one robin is 0.75

The Marked price of an article is rupees 4500. After allowing some percent of discount and levying 10% VAT it is sold at 4400, find discount percentage
Answer:
given,
mp= 4500
now
discount amount=dis%of mp
=x%of 4500
=45x
now,
sp=mp- discount
=4500-45x
now,
vat=vat%of SP
=10%*4500-45x
=450-45x
now,
sp with vat=sp+vat amount
=4500-45x+450-45x
=4950-90x
now,
4950-90x=4400
or,-90x=-550
or, x=55/9
or, x=6.11%
therefore, dis percent is 6.11%
9514 1404 393
Answer:
11.11%
Step-by-step explanation:
Let d represent the discount, as a fraction. Then the final price is ...
4500(1 -d)(1 +10%) = 4400
1 -d = 4400/(1.10·4500)
d = 1 - (4400/4950) = 0.111... ≈ 11.11%
The discount percentage is about 11.11%.

Answer:
One: x = 3/32
Two: y = 3/10
Step-by-step explanation:
One
y = k*x
1/4 = k* 1/8 Multiply both sides by 8
8(1/4) = 8*k*(1/8)
8/4 = k
k = 2
=======================
3/16 = 2*x Divide by 2
3/32 = x
Two
y = 2/5
x = 1/3
2/5 = k * 1/3 Multiply both sides by 5
2 = 5*k * 1/3
2 = 5/3 * k Multiply both sides by 3
6 = 5 * k Divide both sides by 5
6/5 = k
y = 6/5 * x
x = 1/4
y = 6/5 * 1/4
y = 6/20 = 3/10

Answer:
C) 78,200
Step-by-step explanation:
If p represents the population in 2010, then the population in 2012 is ...
p + 0.30p = 1.30p
and the population in 2014 is ...
(1.30p) + 0.20(1.30p) = (1.30p)(1.20) = 1.56p
This is the same population as in 2015, so we have ...
1.56p = 122,000
p = 122,000/1.56 ≈ 78,200 . . . . rounded to hundreds
In 2010, the population of Maple Mall was about 78,200.
