Answer:
HCF=4
LCM=10080
HCF x LCM = Product of the two given numbers is verified because 403200=40320
Step-by-step explanation:
HCF of 160 and 252
HCF is the product of common prime factors
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
HCF= 2x2
HCF=4
40 and 63 doesn't come in any other table together so,
HCF= 2 x 2 = 4
Now, finding LCM of 160 and 252
LCM is the product of all factors of both numbers, while if any factor is common, it is considered once.
Prime Factorisation of 160: 2x2x2x2x2x5
Prime Factorisation of 252: 2x23x3x7
In the given factors 2x2 is common so, it is considered once.
LCM= 2x2x2x2x2x3x5x7
LCM= 10080
Now, checking:
HCF x LCM = Product of the two given numbers.
4x10080=160x252
403200=40320
So, It is verified that HCF x LCM = Product of the two given numbers.

Step-by-step explanation:
The force required to stretch a spring by 1 m from its unstretched length is 150 N. What is the force required to stretch the spring by 3 m? 450 N
200 N
600 N
300 N
Answer:
450 N.
Step-by-step explanation:
By Hooke's law
Force = k * displacement so
150 = k * 1
So k = 150 and the equation is
F = 150 d
So when d = 3
F = 150 * 3 = 450.

F is the midpoint of EG If EF = x + 2 and FG = 2x - 6, find
FG
Answer:
FG = 10
Step-by-step explanation:
EF = x + 2 ; FG = 2x - 6
F is the mid-point of EG. So, EF = FG
[tex] = > x + 2 = 2x - 6[/tex]
[tex] = > 2x - x = 6 + 2[/tex]
[tex] = > x = 8[/tex]
FG = 2×8 - 6 = 10

Answer:
2x + 3 = -7 ---> x = -5
4.5x - 7 = 20 ---> x = 6
-3x + 7 = 28 ---> x = -7
Step-by-step explanation:
2x + 3 = -7
2x = -10
x = -5
4.5x - 7 = 20
4.5x = 27
x = 6
-3x + 7 = 28
-3x = 21

The line y=-3x - 8 is graphed below. What additional line would create a system of equations with a solution of (-4,4)?
Answer
A y = 2x + 10
By= 3x + 1
C y = 3x - 9
Dy - 3x + 6
Answer:
Choice D
Step-by-step explanation:
For this one I would find if the point lands on the line.
Choice A:
What we have to do is to plug in -4 for x and 4 for y.
[tex]y=2x+10\\(4)=2(-4)+10\\4=-8+10\\4\ne2[/tex]
The point is not on this line so this cannot be it.
Choice B:
We pug what we know again.
[tex]y=\frac{1}{3}x+1\\(4)=\frac{1}{3}(-4)+1\\(4)=-\frac{4}{3}+1\\4\ne-\frac{1}{3}[/tex]
The point is not on this line so it can't be it.
Choice C:
We pug in what we know again.
[tex]y=3x-9\\(4)=3(-4)-9\\(4)=-12-9\\4\ne-21[/tex]
The point is not on this line so it can't be it.
The next one has to be it, but we'll check it just in case.
Choice D:
We plug in what we know again.
[tex]y= \frac{1}{2}x+6\\(4)=\frac{1}{2}(-4)+6\\(4)=-2+6\\4=4[/tex]
The point is on this line so this is the line.
write a linear function with f with f (5) = -1 and f (0) = -5
Answer:
5y = 4x-25
Step-by-step explanation:
Let f(x) be regarded as y
So we have two points
(5,-1) and (0,-5)
We start by finding the slope of the line connecting the two points
m = y2-y1/x2-x1
m = -5+1/0-5 = -4/-5 = 4/5
The general equation of a straight line is;
y = mx + b
where m
is slope and b is the y-intercept
we already have the slope as 4/5
So;
y = 4x/5 + b
To get b, substitute one of the points
Let us use (0,-5)
-5 = 4(0)/5 + b
so b = -5
The equation is;
y = 4x/5 - 5
Multiply through by 5
5y = 4x - 25

FIRST ANSWER GETS BRAINLIEST
Answer:Hello! Here we have a cube, with a mass of 10g and a side length of 2.5cm.
First we want to determine the volume.
The volume of a cube, is equal to his cubic side length, where L is the side length:
So
So the volume of the cube is 15.625 cubic centimeters.
Now we want to calculate te density of the material, as you know:
This means that the density is 0.64 grams per cubic centimeter.
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
1. Determine the value: V=L^3
so, (1.7)^3= 4.913
2. Calculate the density: mass divided by volume
10 divided by 4.913= 2.0

Suppose that three out of five voters support a candidate. If 1,240 voters support the candidate, how many voters participated in the election in all? Round your answer to the nearest whole number.
Answer:
2067 voters
Step-by-step explanation:
Suppose that three out of five voters support a candidate.
This means 3/5 votes support a candidate
Let the total number rod candidates be represented as x
If 1,240 voters support the candidate,
how many voters participated in the election in all?
Hence,
3/5 of x = 1240 voters.
3/5 × x = 1240
3x /5 = 1240
Cross Multiply
3x = 1240 × 5
x = 1240 × 5/3
x = 2066.6666667 voters
Approximately to the nearest whole number:
2067 voters
