Step-by-step explanation:
the numbers skip by 20
Answer:
-4
Step-by-step explanation:
If you look at the table closely for the value of x decreases by 2 like the first value is 7 then it goes to 5 then it goes to 3 then to 1, and if you look at the values of y it decreases by 20 like the first number is 66 then 46 then 26 then 6.
But in the table it asks the missing value of y when x is 0 not -1 so for difference of 1 instead of the usual 2 in the pattern the value of y would decrease by 10 instead of 20 so 6-10 would be -4
so the missing value of y is -4
Simplify:
A -6i
B 6i (sqrt 2)
C -6i (sqrt -2)
D 6i
Answer:
A and D
Step-by-step explanation:
Given
[tex]\sqrt{-36}[/tex]
= ± [tex]\sqrt{36(-1)}[/tex]
= ± [tex]\sqrt{36}[/tex] × [tex]\sqrt{-1}[/tex]
= ± 6i
That is - 6i or 6i

Step-by-step explanation:
Write an equation for the line parallel to the given line that contains C.
C(2,8); y = - 2x + 1
y =
Okay!
Whenever a line is parallel to another, that means they ALWAYS have the same slope!
So the slope of our new line is -2 as well !
Now let's use point C (2, 8) to find the y-intercept!
This is easy! All we need to do is plug the point in our new equation!
Remember that in point C, 2 = x and 8 = y
Time to plug in all these numbers in y = mx + b
8 = -2 (2) + y intercept
→ the 8 is in the y's place
→the -2 is in the slope place
→2 is in the x place
Now we solve for the y-intercept using basic math!
8 = -2(2) + y-intercept
8 = -4 + y-intercept
8 + 4 = y-intercept
We did it! We found the y-intercept
The y-intercept is 12!
Now let's create our final equation ...
y = -2x + 12
How many Triangles are in this Triangle
Answer:
7
Step-by-step explanation:
The number of triangles in the figure is given as 15 triangles.
Given that,
To determine the number of triangles inside the triangles.
In arithmetic, combination and permutation are two different ways of grouping elements of a set into subsets. In combination, the components of the subset can be recorded in any order. In a permutation, the components of the subset are listed in a distinctive order.
here,
here in the figure inside the parent figure, there are 6 segments that contribute two triangles in the figure,
Number of triangle = 6C2
Number of triangle = 15
Thus, the number of triangles in the figure is given as 15 triangles.

1995. Were 57 million cats as pets in the U.S. By 2003this number was 61 millionWrite a linea model for the number of cats as pets. Then use the model to predict the number of cats as pets in 2015
Answer:
Cats as pet in 2015 = 6 million
Step-by-step explanation:
Given:
Cats as pet in 1995 = 57 million
Cats as pet in 2003 = 61 million
Find:
Cats as pet in 2015
Computation:
Difference in year = 2003 - 1995
Difference in year = 8 year
Difference in year = 2015 - 2003
Difference in year = 2015 - 2003
Difference in year = 12 year
Difference in number = 61 - 57
Difference in number = 4 million
So,
Cats as pet in 2015 = 4 million x [12/8]
Cats as pet in 2015 = 6 million

Step-by-step explanation:
In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.
The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.
Basically:
[tex]x^2 + y^2 = h^2[/tex]
Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:
[tex]x^2 = h^2 - y^2[/tex]
[tex]x=\sqrt{h^2 - y^2}[/tex]
Then plug in the values:
[tex]x = \sqrt{16^2 - 10^2} = \sqrt{256-100}=\sqrt{156} = 2\sqrt{39}=12.489996[/tex]

What is Distributive Property?The distributive property is also known as the distributive law of multiplication over addition and subtraction. The name itself signifies that the operation includes dividing or distributing something. The distributive law is applicable to addition and subtraction. Let us learn more about the distributive property in this page.
The distributive property states that an expression which is given in form of A (B + C) can be solved as A × (B + C) = AB + AC. This distributive law is also applicable to subtraction and is expressed as, A (B - C) = AB - AC. This means operand A is distributed between the other two operands.
Given:
48 + 72
Now, factorize the above into prime factors
48 = 2 x 2 x 2 x 2 x 3
and, 72 = 2 x 2 x 2 x 3 x 3
Now, rewriting
48 + 72
= 2 x 2 x 2 x 2 x 3 + 2 x 2 x 2 x 3 x 3
= 2 x 2 x 2 x 3 (2 + 3)
=24 (2+3)
Hence, the expression can be written as 24 (2+3).

Zayed is helping his classmates get ready for their math test by making them identical packages of pencils and calculators.
He has 72 pencils and 24 calculators and he must use all of the pencils and calculators.
If Zayed creates the greatest number of identical packages possible, how many pencils will be in each package?
Answer: 3 Pencils
Step-by-step explanation:
In order to know how many packages Zayed can make, we need a number that is a factor of 72 and 24, so that the 72 pencils and the 24 calculators can be divided evenly.
So, if there wre 2 packages, there would be 72 / 2 = 36 pencils 24/ 2= 12 calculators in each package. This creates packages, but isn't the gratest number of packages!
To find the greatest number of identical packeges, we want to found the greatest common factor of 72 and 24
To do so, lets find the factors of 72 and 24
72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72
24: 1, 2, 3, 4, 6, 8, 12, 24
the gratest common number factor of 72 and 24 is 24. in math notation this looks like:
gcf (72, 24)=24
the gratest number of identical packages can make is 24
To find the umber of pencils in each pacage, we need to dovide the total number of pencils by the number of pakages:
72 / 24 = 3.
there will be 3 pencils each package
