Is PQRST a scaled copy of ABCDE? Explain your reasoning. HELP PLEASE
Answer:
No.
Step-by-step explanation:
For polygon PQRST to be considered a scaled copy of polygon ABCDE, it means every segments of polygon ABCDE were increased proportionally by a scale factor.
The segments in polygon PQRST were not gotten using the same scale factor, hence, it is not a scaled copy of the original polygon, ABCDE.
Segment CD = 2 units, it corresponds to segment RS = 4 units. Scale factor = RS/CD = 4/2 = 2
Segment BC = 1 unit, it corresponds to segment QR = 1 unit. Scale factor = QR/BC = 1/1 = 1 units.
Varying scale factor shows polygon PQRST is not a scaled copy of polygon ABCDE.

Which of these is an example of acceleration? a bicyclist turning around a corner a car traveling south with its cruise control set a bus traveling north at 25m/s a helicopter waiting to take off
Answer:
A
Step-by-step explanation:
An example of acceleration is:
a bicyclist turning around a corner
----------------------
The acceleration is given by the rate of change of the velocity. It the object is stopping, the velocity is decreasing, and thus, the acceleration is negative, and if the object is accelerating, the velocity is increasing, and thus, the acceleration is positive.For the first option, of a bicyclist turning around a corner, he decreases the velocity to take the corner, then after the corner, the velocity increases again, thus, it is an example of acceleration.For the other options, in all cases, the velocity is constant, and thus, the acceleration is zero, that is, there is no acceleration.For more on acceleration, you can check https://brainly.com/question/14516604

Evaluate 3^2 + (7 − 2) ⋅ 4 − 6 over 3
Answer:
7.7
Step-by-step explanation:
we basically follow the BEDMAS rule
1st we workout the bracket (7-2)=5
2nd the exponent 3^2=9
3rd the multiplication (7-2) . 4 = 5 . 4 = 20
4th addition 9+20=29
5th step is subtraction 29-6=23
the final step is dividing 23 by 3, which will become 7.7
Answer: 27
Step-by-step explanation:
Use PEMDAS

Help with domain and range.
Answer:Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.

Which is the name of a rat with endpoint A?
Answer:
AB
Step-by-step explanation:
A ray has one endpoint and the rest is a line, so AB would be the only answer that would make sense in this situation (because it's starting from A and B is a point on the ray).
Point B is 1/3 of the way from A to C. What are the coordinates of C?
A = (-4 , -7)
B = (12 , 5)
Answer: C=(44,29).
Step-by-step explanation:
The given points are A = (-4 , -7) and B = (12 , 5).
It is given that Point B is 1/3 of the way from A to C.
AB:AC=1:3
AB:BC=AB:(AC-AB)=1:(3-1)=1:2
It means point B divides the line segment AC in 1:2.
Let coordinates of C are (a,b).
Section formula: If a point divides a line segment in m:n, then
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Using section formula, we get
[tex]B=\left(\dfrac{1(a)+2(-4)}{1+2},\dfrac{1(b)+2(-7)}{1+2}\right)[/tex]
[tex](12,5)=\left(\dfrac{a-8}{3},\dfrac{b-14}{3}\right)[/tex]
On comparing both sides, we get
[tex]\dfrac{a-8}{3}=12[/tex]
[tex]a-8=36[/tex]
[tex]a=36+8[/tex]
[tex]a=44[/tex]
[tex]\dfrac{b-14}{3}=5[/tex]
[tex]b-14=15[/tex]
[tex]b=15+14[/tex]
[tex]b=29[/tex]
Therefore, the coordinates of C are (44,29).
Ken puts 4 fluid ounces of bubble mix into each bowl. How many bowls can he fill with 1 pint of bubble mix?
Answer:
4 bowls
Step-by-step explanation:
Conversion rate :
1 liquid pint = 16 fluid ounces
From the question, we are told that :
4 fluid ounces of bubble mix = 1 bowl
16 fluid ounces of bubble mix(1 liquid pint) = y bowl
Cross Multiply
4 fluid ounces × y bowl = 16 fluid ounces × 1bowl
y bowl = 16 fluid ounces × 1bowl/4 fluid ounces
= 4 bowls
Therefore, he can fill 4 bowls with 1 pint of bubble mix

Answer:
NUMBER 2) x>_3/7
Step-by-step explanation:
-2(2-2x)-4(x+5) is less than or equal to -24
-2(2-2x)-4(x+5) <_ -24 Divide the expression by the #'s outside the ()
2-2x+x+5>_-3 This is the quotient from dividing it by -8 (-2 and -4)
(when you divide by a negative number, the signs flip)
7-x>_-3 Now, divide both sides by 7
-x>_-3/7 If you want, convert to a decimal. Lastly, divide by -1

The data in the table above was compiled by a new pet information website from a random survey of users with Basset Hounds and Welsh Corgis. Which statement best compares the height of the two breeds based on the collected data?
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
There is no noticeable difference in the height of the two breeds since the Mean Absolute Deviation for each breed is roughly the same.
It is impossible to make a valid conclusion because the sample sizes are too small.
Answer:
An adult Welsh Corgi is always going to be shorter than an adult Basset Hound.
Step-by-step explanation:
That's what I think because the Basset Hound is 13.8 in. in height right? So he's two inches taller if we round up both numbers. Basset hound would be 14 and welsh corgi would be 11....................okay im not sure i give up but it's either
"An adult Welsh Corgi is always going to be shorter than an adult Basset Hound."
"Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
whichever just not the other ones good luck!
Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
What is mean?
Mean is actually the average of all the observations.
What is absolute mean deviation?Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
of a data set is the average distance between each data value and the mean.
How to know which statement best compares the height of the two breeds based on the collected data?According to the problem,
Mean height of Basset hounds is 13.8Mean height of Welsh Corgis is 11.1 Mean absolute deviation of height of Basset hounds is 1.9Mean absolute deviation of height of Welsh Corgis is 1.2Here we can say, the average height of Basset hounds is 13.8 and is highly dispersed in comparison to Welsh Corgis
So, we can say Basset hounds tend to be a little over two inches taller than Welsh Corgis, but have a higher variability in height.
