Given that a x b = 70, work out the value of 3b/a
Answer:
the value of 3b ÷ a is 3 ÷ 70
Step-by-step explanation:
The computation is shown below:
Given that
a × b = 70
So it could be write as
a = 70 ÷ b
And, the value of 3b ÷ a is
= 3b ÷ 70 ÷ b ÷ 1
= 3b ÷ 70b
= 3 ÷ 70
Hence, the value of 3b ÷ a is 3 ÷ 70
Write an equation in slope-intercept form for the line that passes through (0, 4) and is parallel to y = 3x - 7
Answer:
Step-by-step explanation:
As the line is parallel to the given equation hence it means there slope will be same,
let Y=mx+ c is our required equation ,
y =3x-7 is given so by comparing we get ,
m =3 ( slope )
Now putt the point (0,4) in required equation to get the value of c,
4 =m(0)+c
c=4
now putt the value of m and c in required equation we get ,
y=3x+4

Answer: To establish the strength of a linear association, first compute the correlation coefficient between the variables involved. The, examine the absolute value of the coefficient. A strong relationship has an absolute value of close to 1 (or approaching 1) while a weak relationship has an absolute value close to 0 (or approaching zero).
The data points will be clustered more tightly around the trend line if there is a weak linear association and less tightly if there is a strong one.

How does the circumference of the scaled copy compare to the circumference of the original circle?
Scale factor of 2 means green circle is twice the size of blue circle.

Answer:
[tex]B' = (-6,-8)[/tex]
Step-by-step explanation:
Given
[tex]Point\ B = (-6,0)[/tex]
Required
Plot a new point that is 8 units down and also has the same x coordinate
Represent the new point with B'
In [tex]Point\ B = (-6,0)[/tex]
[tex]x = -6[/tex] and [tex]y = 0[/tex]
This means that B' has an x coordinate of -6
Next, is to determine the y coordinate
If a point (x,y) is translated b units down, the new point is (x, y - b)
In this case:
The y coordinate of B is 0 and b = 8. So, the new y coordinate is: 0 - 8 = -8
So, we have:
[tex]B' = (-6,-8)[/tex]

A sel contains eleven elements.
a) How many subsets does it have?
b) How many proper subsets does it have?
Answers:
a) 2048b) 2047=============================================================
Explanation:
If a set has n elements inside it, then it has 2^n different subsets.
Consider a set like {a,b,c}. It has n = 3 elements.
It has 2^n = 2^3 = 8 subsets
Those 8 subsets are...
{a,b,c} ..... any set is a subset of itself{a,b}{a,c}{b,c}{a}{b}{c}{ } .... the empty setAs you can see, each subset consists of items that are selected from the original set {a,b,c}. We can't have any repeat letters.
In that list, items 2 through 4 represent subsets with exactly two things inside it. Items 5 through 7 are known as singletons as they only have one item inside each set. The empty set can be written with the symbol [tex]\varnothing[/tex] or you could have a pair of braces with nothing inside them. The empty set is a subset of any set.
--------------
Note how I included {a,b,c} as a subset. Any set is a subset of itself.
A proper subset will ignore the original set and only look at smaller subsets. If we say B is a proper subset of A, then set B will have fewer items compared to set A. Without the "proper" in there, it's possible that A = B.
So all we've done really is kick out one set which drops 2^n to (2^n)-1 when counting the number of proper subsets. I'm using parenthesis to indicate the "-1" is not part of the exponent. If you wrote this on your paper, then you would likely write [tex]2^{n} - 1[/tex]
--------------
For this problem, n = 11
This means there are 2^n = 2^11 = 2048 subsets and (2^n)-1 = 2048-1 = 2047 proper subsets.
The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.
Here,
A set containing 11 elements.
We have to find number of Subsets and number of Proper subsets.
What is Proper subset of a set?
Set A is considered to be a proper subset of Set B if Set B contains at least one element that is not present in Set A.
Now,
Let a set containing n elements.
then, Number of subsets = [tex]2^{n}[/tex]
And, Number of proper subsets = [tex]2^{n} -1[/tex]
Hence,
A set containing 11 elements.
Number of subsets = [tex]2^{11} = 2,048[/tex]
And, Number of proper subsets = [tex]2^{11} -1 = 2,048 - 1 = 2,047[/tex]
Hence, The number of subset of a set containing 11 elements is 2,048
And, number of proper subset of a set containing 11 element is 2,047.

Answer:
10.12 as a fraction equals 1012/100
Step-by-step explanation:
To write 10.12 as a fraction you have to write 10.12 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
10.12 = 10.12/1 = 101.2/10 = 1012/100
the three angles of a triangle are in the ratio 1:3:5 find the angles
Answer:
The ratio 1:3:5 by doubling each number is the same as 2:6:10 and the big one 10 is 10/(2+6+10) = 10/18 of the total, so multiplying top and bottom by 10 gives 100/180, so the biggest angle is 100° since the sum of all angles must be 180°.

please help!! im don't know this
Answer:
i think its D) 30m+100
Step-by-step explanation:
Hi there!
it would be 30m+100
Expressions can’t have equal signs or just a number so we can cross out A and B...
m-30m means money-30 times money which doesn’t make sense.
30m+100 would be 30m+100 which is correct since the total would be 130$ and if m is 1, then this expression is correct,
Therefore, the expression would be 30m+100.

Answer:
the answer is 1/2...............
The fraction 1/2 which is equivalent to 4/8 is greater than 1/2.
Given fraction to compare 1/8 or 1/2.
To compare the fraction, the denominator of both fraction should be same.
So, to make denominator same take the LCM of 8 and 2 as
8 = 2 x 2 x 2
2 = 2 x 1
Then, the LCM( 8, 2) = 8.
Now, the fraction can be written as
1/8 or 1/2 x 4/4 = 4/8.
Therefore, the fraction 1/2 is greater than 1/8.
