Answer:
42
Step-by-step explanation:
Find the prime factorization of 126
126 = 2 × 3 × 3 × 7
Find the prime factorization of 420
420 = 2 × 2 × 3 × 5 × 7
To find the GCF, multiply all the prime factors common to both numbers:
Therefore, GCF = 2 × 3 × 7
GCF = 42
The highest common factor HCF of 126 and 420 is 42
What is HCF and LCM?The Greatest Common Divisor GCF or the Highest Common Factor HCF is the highest number that divides exactly into two or more numbers. It is also expressed as GCF or HCF
Least Common Multiple (LCM) is a method to find the smallest common multiple between any two or more numbers. A common multiple is a number which is a multiple of two or more numbers
Product of HCF x LCM = product of two numbers
Given data ,
Let the HCF of the two numbers be represented as n
The value of n is
Let the first number be p = 126
Let the second number be q = 420
The factors of 126 = 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 63, 126
The factors of 420 = 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20 , 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210 and 420
So , the highest common factor of the two numbers 126 and 420 is 42
Therefore , the value of n = 42
Hence , the HCF is 42

Evaluate 11.3v + 10.7w when v=7 and w=8
Answer:
164.7
Step-by-step explanation:
So if v= 7 and w=8, then the problem would become - 11.3 x 7 plus 10.7 x 8.
simplified, this would be 79.1 + 85.6, so add that and you should get 164.7
Monica deposits $300 into a savings account that pays a simple interest rate of 4.2% paul deposits $400 into a savings account that pays a simple interest rate of 3.8% monica says that she will earn more interest in 1 year because her interest rate is higher is she correct?
Answer:
Paul earned $2.6 more interest than Monica.
Step-by-step explanation:
Giving the following information:
Monica:
Initial investment= $300
Interest rate= 4.2%
Paul:
Initial investment= $400
Interest rate= 3.8%
To calculate the income earned, we need to use the following formula:
I= P*r*t
P= principal
r= interest rate
t= time
Monica:
I= 300*0.042*1= $12.6
Paul:
I= 400*0.038*1= $15.2
Paul earned $2.6 more interest than Monica.

Answer:
y = 1/2x + 4 1/2
Step-by-step explanation:
(9 , 9) (3 , 6)
slope (m) = Rise (Δy) /run (Δx) = (9-6) / (9-3) = 3/6 = 1/2
(y-6)/(x-3) = 1/2
y-6 = 1/2 (x-3) = 1/2x - 3/2
y = 1/2x + 9/2 = 1/2x + 4 1/2

Answer: (17 , 5)
18 + 16 / 2 = 17
0 + 10 / 2 = 5
Answer:
Step-by-step explanation:
F = (18, 0 ) as ( x1 , y1)
G = (16 , 10) as (x2, y2 )
mid = (x1+x2) / 2 ,( y1 + y2) / 2
mid = (18+16)/2 , (0+10)/2
mid = 34/2 , 10 /2
mid =( 17, 5)
Using the variable n for the term, describe the sequence.
Answer:
3 + 5n
Step-by-step explanation:
This is an arithmetic sequence.
First term = a = 8
Common difference = d =Second term - first term
= 13 - 8
= 5
Nth term = a + (n- 1)*d
= 8 + (n -1) * 5
= 8 + n*5 - 1 *5
= 8 + 5n - 5
= 8 - 5 + 5n
= 3 + 5n

Independent practice question x/8-1/2=-7/2
Answer:
x = -24
Step-by-step explanation:
If you are to solve for x then multiply everything by 2 so
[tex]\frac{2x}{8}[/tex] - 1 = -7 now multiply everything by 8 to get rid of the fraction
2x - 8 = -56, solve for x so 2x = -48 so x = -24

Answer: BC = 54 <kjm=44
Step-by-step explanation:
1st 0ne-
if you look at it as 2 triangles with D being the shared side- I can determine that the angles are congruent (by SSA theorem)
so
6x=9x-27 (by corresponding parts of congruent Theorem)
-3x=-27
x=9
BC- 9(9)-27= 81-27=54
2nd one-
J bisects KJM
4x+6=3x+10
x=4
3(4)+10= 22
4(4)+6= 22
KJM= 22+22= 44
Answer:
Step-by-step explanation:
BD is the perpendicular disector of isosceles triangle DAC
AB=BC
6x=9x-27
3x=27
x=9
BC=9x-27=54
For triangle JKL and JML,
KL=ML
JL=JL
JK=JM from properties of right-angled triangle
So triangle JKL and JML are congruent
<KJL = <MJL
4x+6=3x+10
x=4
<KJL=4*4+6=22
