Step-by-step explanation:
Calculate the speed of an object from 0-1 sec.
Answer:
. 2 m/s
Step-by-step explanation:
Speed is defined as the rate of change in distance per time.
in this case you can simply observe the graph to get the final and initial distances & time.
The motion starts from 0 and moves to 2 if you look at the y axis of the graph.
Thus, the initial distance is 0m & the final distance is 2m
The time is specified in the question to have an initial of 0 sec and a final of 1 sec.
now let's plot our values out as a given.
S1 = 0m t1 = 0 sec
S2 = 2m t2 = 1 sec
and so you're going to have to find the change in time and displacement individually to later engage both in your formula which is - ∆V = ∆S / ∆t
∆S = S2 - S1 = 2m - 0m = 2m.
∆t = t2 - t1 = 1 sec - 0 sec = 1 sec.
∆V = ∆S / ∆t = 2m / 1 sec = 2m/sec (2m/s)

Step-by-step explanation:
half the product of two number a and b, added to thrice a third number c
Answer:
ab/2 +3c
Step-by-step explanation:
Maybe you want to translate this to an algebraic expression.
__
The product of a and b is written ab.
Half that can be 1/2ab or ab/2. The latter tends to be less ambiguous.
Thrice c is 3c.
So, your expression is ...
ab/2 +3c

Answer:
8.9k
Step-by-step explanation:
Perimeter is the area around the object.
1.8k - 5 + 3.5 + 6.1k + k + 1.5
Combine like terms:
1.8k + 6.1k + k = 8.9k
-5 + 3.5 + 1.5 = 0
Therefore 8.9k is the answer. You dont need to include the +0 because it will not add anything to the answer. In the most simplified form, the answer is 8.9k

Write the properties of each triangle.
Draw a circle and name the different parts of the circle.
Find the relationship between radius and diameter.

Answer:
Explanation :How many different types of triangles are there?
There are 6 types of triangles.
➝ Scalene Triangle➝ Isosceles Triangle➝ Equilateral Triangle➝ Acute Triangle➝ Obtuse Triangle➝ Right Triangle[tex]\begin{gathered}\end{gathered}[/tex]
Draw and name the 4 different triangles.
[tex]\green\implies[/tex] The diagram of 4 different triangles is in the given pic. So, please check out the attachment.
The name of four triangles are :
➝ Right angled triangle ➝ Isosceles triangle ➝ Equilateral triangle ➝ Scalene triangle[tex]\begin{gathered}\end{gathered}[/tex]
Write the properties of each triangle.
1. Acute-angled Triangle
[tex]\pink\implies[/tex] Each of the angles is below 90⁰, and the sum of those angles is always 180⁰.
2. Right-angled Triangle
[tex]\pink\implies[/tex] One side being 90⁰, the other angles have to be acute. It is because the addition of all internal angles always produce 180⁰.
3. Obtuse-angled Triangle
[tex]\pink\implies[/tex] Naturally, the other two angles have to be smaller than an obtuse angle. It is so that the internal sum of all the angles remains 180⁰.
4. Equilateral Triangle
[tex]\pink\implies[/tex] Since the internal angles add up to 180⁰, each angle has to be equal in an equilateral triangle. In this case, each angle of this triangle is 60⁰.
5. Isosceles Triangle
[tex]\pink\implies[/tex] Since two sides have the same length, the third side has to have a different length. On top of that, the angle of the other side is also dissimilar to the previous angles.
6. Scalene Triangle
[tex]\pink\implies[/tex] In this case, the lengths of the three sides are diverse. However, the sum of dissimilar internal angles also has to be 180⁰.
[tex]\begin{gathered}\end{gathered}[/tex]
Draw a circle and name the different parts of the circle.
[tex]\green\implies[/tex] The diagram of circle is in the given pic. So, please check out the attachment.
Parts of circle :
A circle can have different parts and based on the position and shape, these can be named as follows:
➝ Centre➝ Radius➝ Diameter➝ Circumference➝ Tangent➝ Secant➝ Chord ➝ Arc➝ Segment➝ Sector[tex]\begin{gathered}\end{gathered}[/tex]
Find the relationship between radius and diameter.
[tex]\pink\implies[/tex] The relationship between radius and diameter is the diameter of a circle is twice of its radius.

Pls explain how to solve it! (Will mark brainylist)
Answer:
1,1
Step-by-step explanation:
x=1
y=1
if this is substitution then x IS 7y-6 so then you can replace the x in the other problem with 7y-6 but since it is 5x you will need to do 5(7y-6) which is 35y-30-4y=1
add 30 to both sides to get 35y-4y=31
subtract 4y from 35y to get 31y=31 get the y alone by dividing 31 from both sides to get y=1. then replace the y in the problem where the x is already alone to get x=7×1-6
7x1 is 7 so then 7-6=1 and that gives us x=1.
Hope this helped

Give two systems of equations that would be easier to solve by substitution than by elimination. Then give two systems that would be easier to solve with elimination. Finally, explain how you decide whether to use elimination or substitution to solve a system.
Answer:
These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.
Step-by-step explanation:
Just to add a bit more information, "Elimination" Can have a variety of other interpretations. Elimination techniques typically refer to 'row reduction' to achieve 'row echelon form.' Do not worry if you have not heard of these terms. They are used in Linear Algebra when referring to "Elimination techniques"
Gaussian Elimination
Gauss-Jordan Elimination
LU-Decomposition
QR-Decomposition
These techniques for elimination are preferred for 3rd order systems and higher. They use "Row-Reduction" techniques/pivoting and many subtle math tricks to reduce a matrix to either a solvable form or perhaps provide an inverse of a matrix (A-1)of linear equation AX=b. Solving systems of linear equations (n>2) by elimination is a topic unto itself and is the preferred method. As the system of equations increases, the "condition" of a matrix becomes extremely important. Some of this may sound completely alien to you. Don't worry about these topics until Linear Algebra when systems of linear equations (Rank 'n') become larger than 2.
Substitution is the preferred method for 2 equations in 2 unknowns. The constants are unimportant other than having a non-zero determinant. It is always easy to find multiplicative factors using LCMs of one variable or the other to allow substitution into the other equation:
Example:
4X + 5Y = 9
5X - 4Y = 1
Notice that 20 is a LCM of either the X or Y variable. So multiply the first by 4 and the second by 5 and then adding the two (Y's will drop out allowing for substitution)
4(4X + 5Y = 9)
5(5X - 4Y = 1)
Multiplying to produce the LCM factors:
16X + 20Y = 36
25X - 20Y = 5
Adding the equations
41X = 41
X = 1
Substitution into either equation yields
Y = 1
Elimination techniques are preferred for Rank-n>3

5p coins weigh approximately 3 grams
what would the weight of £5 worth of 5p coins ?
give your answer in kg
Answer:
0.3kg(300g)
Step-by-step explanation:
£1=100p
£5=500p
5p=3g
500p=x
x=500*3/5
x=300g
Step-by-step explanation:
£5 in pence is 500p
The number of 5p coins in 500p is:
500/5 = 100 (5p coins)
each 5p coin weighs 3g
therefore the £5 weighs in grams:
3x100 = 300g
To change to Kg: 300/1000 = 0.3 Kg
