Out of 153 students appeared in an examination the ratio of the students who got the A+ A and B+ grades is 2:4:5 and if 21 students got the other grades then, how many students got the A+, A and B+ grades?
Step-by-step explanation:
153 - 21 = 132
132 / 11 = 12
Hence 24 students got A+, 48 students got A, and 60 students got B+.

SubstitutionStep-by-step explanation:
Step 1: Define

Solution set (-1, -5)
Step 2: Check
Substitute: -5 < -3/4(-1) - 1Multiply: -5 < 3/4 - 1Subtract: -5 < -1/4Here we see that -1/4 is indeed bigger than -5.

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

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]

What is the difference from the origin to point A graphed on the complex plane below?
Answer:
Origin is applicable for coordinate system. Distances are measured from origin and at a particular point distances are expressed in the form of coordinates.
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

characterize the slope of the line in the graph
Answer:
Please check the attached graph.
Step-by-step explanation:
Note: You did not add the graph; so I am taking a sample graph to clear the concept anyway. Please check the referred graph attached below.
The slope on the graph basically tells us the time rate of change.
In other words, it describes the steepness of a straight line.The slope can also be termed as:
Slope = rise / runFrom the attached graph, taking twp points
(0, 3)(-1, 0)Finding the slope between (0, 3) and (-1, 0) using the formula
[tex]\left(x_1,\:y_1\right)=\left(0,\:3\right),\:\left(x_2,\:y_2\right)=\left(-1,\:0\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-3}{-1-0}[/tex]
[tex]m=3[/tex]
Thus, the slope of the given line on the graph = m = 3

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.

Please help with 15.
Answer:
negative 16
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

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).
