Answer:
591
Step-by-step explanation:
The length of w from the given triangle UVW is 591 cm.
What is cosine rule?The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them. The law of cosine states that: a² = b² + c² - 2bc·cosA.
Given that, in ΔUVW, u = 480 cm, v = 180 cm and ∠W=120°.
w² = u² + v² - 2uv·cosW
w² = 480² + 180² − 2×480×180·cos120°
w² = 230400 + 32400 - 172800·(-0.5)
w² = 349200
w = √349200
w = 590.93
w = 591 cm
Therefore, the length of w is 591 cm.

A. Small dogs median is larger than housecats.
B. Overall, house cats weigh more with less variation.
C. Overall, small dogs weigh more with less variation
D. Small dogs and housecats have the same median.
Answer:
B.
Step-by-step explanation:
For reference, the median for housecats is 11 and the median for small dogs is 9. So, by process of elimination, B is the correct answer.
The dot plot is solved and Overall, house cats weigh more with less variation.
What is a dot plot?A dot plot, also known as a dot chart or dot graph, is a type of data visualization that displays the frequency of values in a dataset. It is a simple graphing technique that uses dots to represent data points on a horizontal or vertical axis.
Each data point in the dataset is represented by a dot placed above the corresponding value on the axis. If there are multiple data points with the same value, the dots are stacked vertically above that value. The resulting plot shows the distribution of data points along the axis, with the height of the stack of dots representing the frequency of each value.
Given data ,
Let the dot plot be represented as A and B
where the weights of house dogs and small dogs are plotted
Now , the median of house cats = 11
The median of small dogs = 9
Variation refers to the spread or dispersion of a set of data points. It measures how much the values in a dataset differ from the mean or from each other. There are several ways to calculate variation, including the range, variance, and standard deviation.
So , Overall, house cats weigh more with less variation.
Hence , the dot plot is solved

Mason pulled his hamstring while at track practice and received an MRI. His medical bills totaled
$1,200. How much would he have to make in order to pay his bills if he did not use an FSA or HSA?
Answer:
a minimum of $1,200
Step-by-step explanation:
The flexible spending accounts (FSA) and health savings accounts (HSA) are basically accounts that help pay for your medical bills and therefore, drastically reduce the total amounts that you would have to pay out-of-pocket. Therefore, in this scenario, if Mason does not use an FSA or HSA then he would have to make a minimum of $1,200 to completely pay off his medical bill in full. Otherwise, he would still owe money.

which figure is a translation of Figure A? explain. A translation, or slide, is a transformation that moves every point of a figure the same distance & the same direction.
Answer:
Figure B
Step-by-step explanation:
A translation does not "flip" the position of the pre-image. Figure C is a reflection of figure A.
A translation would "slide" the figure into a new position without mirroring nor rotating it.
Figure B should be the translation of Figure A.
Hope this helps.
Figure B is the translation of figure A by 2 units up.
What is the transformation of the graph?If a graph is translated and rotates by any amount either in x and y direction then it will be transfomation of the graph.
For example transformation of graph f(x) by 2 units down.
The new resultant graph could be only translated or rotated or both.
Given figure A
If we look at C then the face of this is towards the right but in figure A the face is towards the left.
So it means C will translate + rotation of graph A it will not be pure translation.
In figure B it is clear that it is a translation of figure A by 2 units upward.
Hence "Figure B is the translation of figure A by 2 units up".

What is the equation of the line that passes through the point (5, – 7) and
has a slope of o?
Answer:
The answer is
[tex]y = - 7[/tex]
Answer:
y = -7
Step-by-step explanation:
Hey :)
y = mx + b
*m is equal to the slope...
y = (0)x + b
Plug in the point you have...
-7 = (0) (5) + b
-7 = 0 + b
-7 = b
y = (0)x - 7
y = -7
Ignore the (0)x because anything multiplied by 0 is 0 so there's no point in having 0x in your equation.
Answer: y = -7

What is the measure of ∠BCE, in degrees, in the figure shown?
Answer:
25 degrees
Step-by-step explanation:
So a triangles angels equal 180 degrees
So for angel ECD 180 - (15+90) = 75
Straight lines also always equal to 180 degrees so
180 - (80+75) = 25
Measure of ∠BCE = 25° .
What is angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle. The word “angle” is derived from the Latin word “angulus”, which means “corner”.
Given, In figure,
∠CED = 15°
∠EDC = 90°
∠BCA = 80°.
In triangle ECD
Sum of all interior angles of a triangle is 180°
∠ECD +∠CED +∠EDC = 180°
∠ECD + 15° + 90° = 180°
∠ECD = 180° - 105°
∠ECD = 75°
Now,
∠BCA,∠BCE and∠ECD are at point C on line AD.
Sum of all angles made at one point of line is 180°.
∠BCA +∠BCE +∠ECD = 180°
80° + ∠BCE + 75° = 180°
∠BCE = 180° - 155°
∠BCE = 25°
Hence, 25° is measure of ∠BCE.

The velocity of a car increases from 4 m/s at 2 sec. To 32 m/s at 9 sec. What is the car's average acceleration?
Answer:
Acceleration, [tex]a=4\ m/s^2[/tex]
Step-by-step explanation:
Given that,
Initial speed = 4 m/s at 2 seconds
Final speed = 32 m/s at 9 seconds
We need to find car's average acceleration. We know that average acceleration is equal to the change in speed divided by the change in time. So,
[tex]a=\dfrac{v_2-v_1}{t_2-t_1}\\\\=\dfrac{32-4}{9-2}\\\\=\dfrac{28}{7}\\\\=4\ m/s^2[/tex]
So, the car's average acceleration is equal to [tex]4\ m/s^2[/tex].

Solve d=rt for r thanks!!!!
Answer:
Step-by-step explanation:
So you know that distance = rate x time.
9 miles in 1.5 hours
In this case, you know the time (1.5 hours) and the distance (9 miles)
(You can ignore the rest of the chart since the question is just about running.)
What's missing is the rate (r) at which you ran. (Think of it as speed...)
If r x t = d, that means that d ÷ t = r
So plug in what you have: 9 ÷ 1.5 = your rate. And 9 ÷ 1.5 is...
6
So you ran 6 miles per hour. And you can check it: if you went 6 miles in one hour, you could go another 3 miles in another half an hour. That would be 9 miles in 1.5 hours. Check!
