Answer:
Example 1.
A square with side lengths of 5.
5*5 = 25.
So the area would be 25 units ^2
Example 2.
A rectangle with a length of 9 and a width of 4
9*4 = 36
So the area is 36 units ^2
Which orders pair is the solution to the system of equations
Answer: C) (12, -14)
Step-by-step explanation:
I am going to solve by elimination.
Start by subtracting one equation from the other
[tex]y=-x-2\\-(y=-\frac{1}{2} x-8)\\0=-\frac{1}{2} x+6[/tex]
Now solve for x
[tex]0=-\frac{1}{2} x+6\\0-6=-\frac{1}{2} x+6-6\\-6=-\frac{1}{2} x\\(-6)(-2)=(-2)(-\frac{1}{2} x)\\12=x[/tex]
Now sub in x into one of the equations to find the value of y
[tex]y=-(12)-2\\y=-14[/tex]
In a right triangle, the side opposite angle φ has a length of 29.0 meters, the side adjacent to angle φ has a length of 49.5 meters, and the hypotenuse has a length of 57.4 meters. What is the value of cot(φ)?
1.979
1.707
0.586
1.160
The right triangle with sides 29m, 49.5m and 57.4 m has the value of cot φ as 1.707
What is a right angle triangle?A right angle triangle has one of its angles as 90 degrees.
Therefore, it has an opposite, adjacent and hypotenuse side depending on the angle.
oposite side = 29 m
adjacent side = 49.5 m
hypotenuse side = 57.4 m
Therefore,
cot φ = 1 / tan φ
Hence,
tan φ = opposite / adjacent
Therefore,
cot φ = adjacent / opposite
cot φ = 49.5 / 29
cot φ = 1.70689655172
cot φ = 1.707

A scientist conducted an experiment to measure the effect of apple cider vinegar on blood sugar levels. The scientist randomly selected
200 adults and randomly assigned them to two subject groups. The first subject group received an apple cider vinegar supplement, and the
second subject group received a placebo. The scientist was aware of which subjects were assigned to each group.
This experiment is
because
know which treatment group each subject is in
Answer:
The first one is blinded. I didn't get the other one though. The one that says "neither the subjects nor the researchers" is wrong.
Step-by-step explanation:
I use Plato.
The experiment is blindeded because the scientist know which treatment group each subject is in.
What is experiment?Experiment is the scientific approach to determine the properties of some sample by doing some research on it eg. By adding another material, or determination of hypothesis.
What is hypothesis?Hypothesis is the assumption which is made under some evidence which can be proceed further verification or by doing experiment on it.
From the question it is clear that the scientist wants to meassure the effect of apple cider vinegar subject on the blood sugar level.
So here the effect of apple cider vinegar subject on the blood sugar level is hypothesis.
From 200 randomly choosen young groups one half have taken apple cider where other half have taken placebo in order to clarify and study which group has taken which treatment and their effect in their blood sugar level.

The radius of the large sphere is times longer than the radius of the small sphere. how many times the volume of the large sphere is the volume of the small sphere?
The volume of the large sphere shown in the image is, 1/27 times the volume of the small sphere.
What is of volume of sphere?Volume of sphere is the amount of quantity, which is obtained by the it in the 3 dimensional space.
The volume of the sphere can be given as,
[tex]V=\dfrac{4}{3}\pi r^3[/tex]
Here, (r) is the radius of the sphere.
The radius of the large sphere is times longer than the radius of the small sphere. Here in the attached image,
The radius of the large sphere, 18.6 in.The radius of the small sphere is 6.2 in.The ratio of the volume of the large sphere to the volume of the small sphere is,
[tex]\dfrac{V_l}{V_s}=\dfrac{\dfrac{4}{3}\pi (18.6)^3}{\dfrac{4}{3}\pi (6.2)^3}\\\dfrac{V_l}{V_s}=\dfrac{18.6\times18.6\times18.6}{6.2\times6.2\times6.2}\\\dfrac{V_l}{V_s}=\dfrac{1}{27}[/tex]

Answer:
214°
Step-by-step explanation:
The external angle (marked 34°) is equal to half the difference of the arcs ACB and AB.
34° = 1/2(ACB -AB)
Together, the two arcs form a complete circle of 360°, so we have ...
34° = 1/2(ACB -(360° -ACB)) = 1/2(2ACB -360°)
34° = ACB -180° . . . . . . . . . . . . simplify
180° +34° = ACB = 214° . . . . . add 180°
The measure of arc ACB is 214°.
