Students are learning a new dance. The students move forward 2.0 meters and tap their feet. Then they move backward 1.0 meter and clap their hands. Finally, they move 0.5 meter forward and stop. What is the displacement of the dancers from their starting part
Answer:
1.5 meters
Step-by-step explanation:
they first move forward 2 meters and then move backwards 1 meter (1 meter from their starting point, and then they move forward 0.5 meters. So the displacement of the dancers from their starting point is 1.5 meters.
0 + 2 = 2
2 - 1 = 1
1 + 0.5 = 1.5
hope this helps!

Maggi buys 3/4 pound of blueberries and uses 3/5 of them to make a smoothie. How many pounds of blueberries did Maggi use to make the smoothie
Answer:
[tex]\dfrac{9}{20}\ \text{pounds}[/tex]
Step-by-step explanation:
Given that,
Maggi buys 3/4 pound of blueberries
He uses 3/5 of them to make a smoothie.
We need to find how many pounds of blueberries Maggi use to make the smoothie. It means we need to find 3/5 of 3/4. So,
[tex]x=\dfrac{3}{4}\times \dfrac{3}{5}\\\\=\dfrac{9}{20}\ \text{pounds}[/tex]
So, he will use [tex]\dfrac{9}{20}\ \text{pounds}[/tex] of blueberries to make a smoothie.
Answer: 9/20
Step-by-step explanation: Maggi buys 3/4 pound of blueberries
He uses 3/5 of them to make a smoothie.
We need to find how many pounds of blueberries Maggi use to make the smoothie. It means we need to find 3/5 of 3/4. So,
So, he will use of blueberries to make a smoothie.

What is the mass of 3.13 x 1023 molecules of carbon dioxide?
Answer:
The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.
Step-by-step explanation:
Avogadro's Number or Avogadro's Constant is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and it applies to any substance.
Then you can apply the following rule of three: if 6.023*10²³ molecules are present in 1 mole, 3.13*10²³ molecules are present in how many moles?
[tex]moles=\frac{3.13*10^{23}molecules*1 mole }{6.023*10^{23}molecules}[/tex]
moles= 0.52
Since the molar mass of carbon dioxide is 44 g / mole, then the following rule of three can be applied: if there are 44 g in 1 mole, how much mass is there in 0.52 moles?
[tex]mass=\frac{0.52 moles*44 g}{1 mole}[/tex]
mass= 22.88 g
The mass of 3.13*10²³ molecules of carbon dioxide is 22.88 g.

If solving a system of linear equations by elimination or substitution I get that 0=0, as final or intermediate step depending on the system, it means (check all that apply)
I have definitely made a mistake and need to review the result
If the system of equations is 2 linear equations in 2 variables, there is infinity number
of solution
If the system of equations is 3 linear equations in 3 variables, there might be infinite
number of solutions
If the system of equations is n linear equations in n variables, there is one unique solution
Answer:
If I get 0=0 then it means:
If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutionsIf the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutionsStep-by-step explanation:
Linear equation systems can consist of two or three equations with two or three unknowns respectively.
A system of linear equations in two variables has infinite solutions when the lines made by them overlap each other and similarly a system with three variables has infinite solutions when two lines overlap each other and third plane is parallel to them
Hence,
If I get 0=0 then it means:
If the system of equations is 2 linear equations in 2 variables, there is infinity number of solutionsIf the system of equations is 3 linear equations in 3 variables, there might be infinite number of solutionsCaroline, Krutika and Natasha share some sweets in the ratio 2:5:3. Caroline gets 12 sweets. How many more sweets does Krutika get over Natasha?
Answer:
12 sweets
Step-by-step explanation:
2:5:3.
caroline gets 12 so multiply the ratio by 6.
12:30:18
Krutika has 30, Natasha has 18.
30-18=12
so 12 sweets

To find the equation of the parabola, first let's write the parent function,
y = a(x-h)^2+k. Ok, now we need to find the vertex and plug it in. Remember, (h,k). When we look at the problem the vertex is (0,4). Therefore we write it as y = a(x-0)^2 +4 or y = ax^2 + 4. Now we need to look to see if it was stretched or compressed. Keep in mind that on a normal parabola, if you move over 1 you go up one. If you move over 2 you go up four. If you move over 3, you go up 9. In this problem, you move over 1, you go up 1. If you move over 2, you go up 4. If you move over 3, you go up 9. From this information, we see that there is no stretch or compression. Therefore the equation of the graph shown is:
y= x^2 +4

Find the distance between (-6,8) and (10,-4)
Answer:
use the distance formula you can find it on the net
The distance between (-6,8) and (10,-4) is 20 units.
What is the distance between two points ( p,q) and (x,y)?
The shortest distance (length of the straight line segment's length connecting both given points) between points ( p,q) and (x,y) is:
[tex]D = √[(x-p)² + (y-q)²] D = \sqrt{(x-p)^2 + (y-q)^2} \: \rm units.[/tex]
We are given that;
The points (-6,8) and (10,-4)
Now,
To use the formula, you need to plug in the values of x1, y1, x2 and y2 into the formula and simplify. For example, to find the distance between (-6,8) and (10,-4), you can do:
d = (10 - (-6))^2 + (-4 - 8)^2
d = (16)^2 + (-12)^2
d = 256 + 144
d = 400
d = sqrt(400)
d = 20
Therefore, the distance formula the answer will be 20 units.

A tire shop promotes its business using a large model of a tire on its roof. The
model tire uses a scale in which 2 feet represents 3 inches. The actual tire used
to create the model tire has a diameter of 33 inches.
What is the diameter of the model tire on the shop's roof
Help plz!!! I need the work shown
Answer:
Ok, so this tire is 2 feet which is represented by 3 inches.
So, since the tire has a diameter of 33 inches, we multiply 33 by 3
33 times 3 is 99.
The diameter of the motel tire on the shop's roof is 99 inches.

A pre-image arrow pointing east is rotated 135° clockwise. In which direction is the image arrow pointin
Given :
A pre-image arrow pointing east is rotated 135° clockwise.
To Find :
In which direction is the image arrow point.
Solution :
90° clockwise shift make it south.
Now, remaining angle for rotation ( 135 - 90 )° = 45°.
So, direction of moving 45° more clockwise makes it 45° west of south or 45° south of west.
Hence, this is the required solution.

A recipe requires 7/8 stick of butter for each 1 1/4 cups of flour. Find the unit rate of sticks of butter to cups of flour.
Answer:
Let R = unit rate
R = (7/8) ÷ 1_1/4
R = (7/8) ÷ (5/4)
R = (7/8) • (4/5)
R = (7/2) • (1/5)
R = 7/10
