Which of these statements is true about the two graphed parallelograms?
Answers
Answer:
They are similar, because one can be obtained by dilating the other about the origin with a scale factor of 1/2.
Explanation:
The dilation of a shape is similar to the original shape; this is because the corresponding side lengths are proportional.A scale factor is how many times larger or smaller the image will be relative to the preimage. In other words, multiply the x and y-coordinates by the scale factor to get the coordinate points of the image.The image is dilated by 1/2.
Take a look.
The coordinate labels of the preimage include: A, B, C, and D.
The coordinate labels of the image include: A', B', C', and D'.
Coordinates of point A: (2, 8)
Coordinates of point A': (1, 4)
**The preimage's x and y-coordinates multiplied by 1/2 will give you the x and y-coordinates of the image.**

Jerry designed a coat that he thinks could keep people dry during a thunderstorm. He created a prototype that looks just like his drawing. What should Jerry do next?
Answers
Answer:
The next step is prototype testing
Explanation:
The stages of the design process are;
1) Situation analysis
Paper based research is conducted on the situation to obtain the situation parameters
2) Brief writing
With the situation analysis developed above, the brief of the current situation is put down on paper
3) Problem research
The problem is researched and experimented on with the development of a paper based proof of the possible concept
4) Specification writing
The specifications of the problem are outlined
5) List the possible solutions
The possible solutions are brainstormed and listed
6) Preferred solution selection
The preferred solution is selected based on the constraints in the situation
7) Create working drawing/plan
The working design drawing of the selected solution or concept is completed and evaluated for applicability
8) Building of a prototype
The design is converted into a prototype which is a model of the actual solution
9) Testing of the prototype
The prototype is tested for functionality, for ability to work in the intended situation and/or in the intended system
10) Report writing
A report is made on the outcome of the tests for review before production
Therefore, after the prototype is created, stage 8, the next step is the testing of the prototype stage 9.
Is cannabinol soluble in 1-octanol?
Why or why not?
Answers
Answer: Uhmmmm this is what i got...-
Explanation:
It is a matter of fact that the hydrophobic (water-hating) oily compounds of cannabinoids such as CBD, THC and others are not water soluble. The term "water soluble" refers to materials which dissolve in water in a homogenous manner by becoming molecules or ions (such as sugar, alcohol, and salt).

Which best describes the velocity of a person on a merry-go-round? * 1 point zero constant increasing continuously changing
Answers
Answer:
continuously changing
Explanation:
The velocity of a person on a merry-go-round can best be described as continuously changing. This is because the initial velocity before the ride starts would be 0. Once the ride begins, it keeps going faster and faster until it reaches a certain speed. During this time the velocity is increasing. Then it remains constant for a certain period of time and when the ride is over the velocity and speed begins to decrease until ultimately reaching a speed of 0. Therefore, it is continuously changing throughout the duration of the ride.

how many grams of C are in 500g or NaHCO3
Answers
Answer: 71.43g
Explanation: The RMM of NaHCO3 is
23+1+12+16(3)=84.
There is one carbon in NaHCO3 thus there are 1×12g of C in NaHCO3.
Thus
85gNaHCO3-----12g C
500gNaHCO3---- xgram
(500×12)÷84= 71.43

There are several ways to model a compound. One type of model is shown.
4 C's are connected in a line by 3 black lines. The C on the left has 3 H's attached to it each by a black line. The next C has 1 H attached by a black line and 1 O attached by 2 black lines. The next C has 2 H's attached to it by 1 black line each. The last C has 2 H's attached to it by 1 black line each and 1 O attached by a single black line. That O has an H attached to it by 1 black line.

Calculate the pressure exerted by heels of a 100 lb woman in high heels, if the area beneath the heel of each shoe is 0.25 square inch
Answers
Answer:
P = 400 Lb/in²
Explanation:
We are given;
Weight of woman; W = 100 lb
Area beneath heel of shoe; 0.25 in²
Now, we want to find pressure.
Formula is;
P = F/A
Where;
F is force exerted by the object which is equal to weight of the object
A is area covered by object
Thus;
P = 100/0.25
P = 400 Lb/in²
If 2.1 moles of NaCl is dissolved in a solution with a total volume of 7.3 liters, what is the molarity of the solution? Round to two decimals.
Answers
Answer:
The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]
Explanation:
Molarity, or molar concentration, is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species. It is defined as the number of moles of solute that are dissolved in a given volume.
Molarity is calculated as the quotient between the number of moles of solutes and the volume of the solution:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
In this case:
number of moles of solute= 2.1 molesvolume= 7.3 litersReplacing:
[tex]Molarity=\frac{2.1 moles}{7.3 liters}[/tex]
Molarity= 0.29 [tex]\frac{moles}{liter}[/tex]
The molarity of the solution is 0.29 [tex]\frac{moles}{liter}[/tex]
Answer:
M = 0.29 M
Explanation:
We are given;
Number of moles of NaCl; n = 2.1 moles
Total volume of solution; V = 7.3 L
Formula for molarity is;
M = n/L
Thus;
M = 2.1/7.3
M = 0.2878 M
Approximating to 2 decimal places gives;
M = 0.29 M
