Answer:
It is 129
Step-by-step explanation:
Since all the digits in the decimal from right to left are less than 5, they all are nearest to 0
So 129.444 can be rounded to 129.000 or 129

In the polynomial 4x – 3x2 +5, which choice is the ” constant term "?
Answer:
5
Step-by-step explanation:
A constant is a number by itself, without any variables.
[tex]4x-3x^{2} +5[/tex]
As you can see, 4 and 3 are coefficients of [tex]x[/tex] and [tex]x^2[/tex] respectively.
Thus, 5 is the constant term.
the lengh of a rectangular prism is 16 inches and the height is 8 inches. If the volume is 640 in ³, what is the width

The width is 5 because if you multiply 16 by 8 by 5 you will get 640 cubed.
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).
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

OCEAN Humpback whales are known to weigh as much as 8 x 104 pounds. The tiny krill they eat weigh only 2.1875 x 103 pounds. How many time greater than krill are humpback whales?
Answer:
The humpback whales are 37 times bigger than the krills they eat
Step-by-step explanation:
In this question, we are interested in knowing how much bigger are humpback whales compared to krill.
what is simply happening here is to divide the weight of the humpback whales by the weight of the krills.
From the question, weight of humpback whales = 8 * 10^4 while the weight of the krills are 2.1875 * 10^3
So the number of times the humpback whales are bigger is;
(8 * 10^4)/(2.1875 * 10^3) = 36.57 which are approximately 37 times bigger

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

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.

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?

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.
