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.

Step-by-step explanation:

Step 1: Define

y < -3/4x - 1

Solution set (-1, -5)

Step 2: Check

Here we see that -1/4 is indeed bigger than -5.

∴ The ordered pair is a solution.

The expression can be written as 24 (2+3).

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).

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

Answer:

10 months

Step-by-step explanation:

Step one

Given

Chuck has $500

Chuckle wants to save $100 monthly

Let the number of months be x

And the total be y

So

Y=500+100x--------1

Holy has $500

Chuckle wants to save $500 monthly

Let the number of months be x

And the total be y

So

Y=1000+50x--------2

Equate 1 and 2

500+100x=1000+50x

1000-500=100x-50x

500=50x

x=500/50

x=10

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

Answer:

x = 12.489996 ft

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]

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

Answer:

Total income = $588

Given:

Weekly salary = $330

Commission = 6%

Total sales = $4,300

Find:

Total income

Computation:

Total commission = $4,300 x 6%

Total commission = $258

Total income = Weekly salary + Total commission

Total income = $330 + $258
