In the high school band there are two percussionist to every seven marching instruments at the high school bad has a total of 180 members that how many percussionists are on the sidelines
The number of percussionists on the sidelines is 40.
What is a proportion?A proportion is an equation that equalizes two ratios. By dividing the provided values, we may determine the missing value. One way to express the proportion formula is as a: b::c : d = a/b = c/d. Here, a and d are the extreme terms and b and c are the mean terms.Given:
Total number of members in high school band = 180
Let's assume "x" is the number of percussionists that are on the sidelines.
According to the question, there are two percussionists to every seven marching instruments. Then,
Number of members = 7 + 2 = 9
You can write the following proportion knowing that there are 180 total members of the high school band:
[tex]\frac{x}{180} = \frac{2}{9}[/tex]
Solving the proportion to get the value of x,
[tex]x = \frac{2}{9} * 180[/tex]
x = 40
Therefore, there are 40 percussionists on the sidelines.

What is basic algebra ?Algebra is a branch of mathematics that helps translate real-world problems or situations into mathematical formulas. Mathematical operations like addition, subtraction, multiplication, and division as well as variables like x, y, and z are needed to construct a valid mathematical expression. Coordinate geometry, calculus, and trigonometry are just a few of the mathematics topics that involve algebra. A simple algebraic equation is 2x + 4 = 8. Algebraic expressions are the result of performing operations on variables and constants, such as addition, subtraction, multiplication, division, etc. Consider that James and Natalie came up with the notion to arrange matchsticks into numerical patterns when they were fiddling with them.

Dilation by a scale factor of 3 with the origin (0, 0) as the center of dilation, followed by a translation of 1 unit up.
Step-by-step explanation:
If two triangles are said to be similar, their corresponding angles are congruent and their corresponding sides are in the same ratio.
Given vertices of triangle ABC:
A = (0, 0)B = (1, 4)C = (5, 2)To maintain similarity (and thus keep the corresponding angles of both triangles the same) but not maintain congruence, dilate triangle ABC.
Given:
B' = (3, 13)If ΔABC is dilated by a scale factor of 3, with the origin as the center of dilation, B' = (3, 12). If the triangle is then translated 1 unit up, B' = (3, 13), which matches the given coordinate of point B'.
Therefore, the series of transformations is:
Dilation by a scale factor of 3 with the origin (0, 0) as the center of dilation.Translation of 1 unit up.Mapping Rule: (x, y) → (3x, 3y + 1)
Therefore, the coordinates of point C' are:

Point M is the midpoint of AB . AM=2x+9, and AB=8x−50.
What is the length of AM?
Using the midpoint theorem, the length of AM is 43
Calculating Length of a lineFrom the question, we are to determine the length of AM
From the given information,
Point M is the midpoint of AB
Thus,
From the midpoint theorem
We can write that
AM + MB = AB
AM = MB
AM + AM = AB
2AM = AB
Also, from the given information,
AM = 2x + 9
and
AB = 8x - 50
Therefore,
From 2AM = AB
2(2x + 9) = 8x - 50
Solve for x
2(2x + 9) = 8x - 50
4x + 18 = 8x - 50
18 + 50 = 8x - 4x
68 = 4x
x = 68/4
x = 17
But,
AM = 2x + 9
Substituting the value of x
Thus,
AM = 2(17) + 9
AM = 34 + 9
AM = 43
This means the length of AM is 43

a bag contains 3 red marbles, 3 white marbles,, and 5 blue marbles. only white marbles will be added to the bag. how many white marbles should be added to the bag to make the probability of pulling a white marble 50%?
Step-by-step explanation:
a probability is always
desired cases / totally possible cases
a 50% probability means 1/2 or 0.5.
that means
desired cases = 1/2 × totally possible cases
at start we have
3 red
3 white
5 blue
that makes 5 + 3 + 3 = 11 totally possible cases and 3 desired cases.
so, the starting probability to pull a white marble is
3/11.
now, we need to say
(3 + x) = 1/2 × (11 + x) (= (3+x)/(11+x) = 1/2)
to make is simpler we multiply both sides by 2 (so we get rid of the 1/2 fraction).
6 + 2x = 11 + x
6 + x = 11
x = 5
we need to add 5 white marble to give us a 50% probability to pull a white marble.
we have then
3 red
3 + 5 = 8 white
5 blue
that makes 5+8+3 = 16 totally possible cases and 8 desired cases.
so, the probability is
8/16 = 1/2
=> our calculation was correct
The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences.
Then the probability is given as,
P = (Favorable event) / (Total event)
A bag contains 3 red marbles, 3 white marbles, and 5 blue marbles. only white marbles will be added to the bag.
Let 'x' be the number of white marble added. Then the equation is given as,
0.50 = (x + 3) / (x + 3 + 3 + 5)
Simplify the equation, then we have
0.50 = (x + 3) / (x + 3 + 3 + 5)
0.50 = (x + 3) / (x + 11)
0.50x + 5.5 = x + 3
0.50x = 2.5
x = 5
The number of white marbles should be added to the bag to make the probability of pulling a white marble 50% will be 5.

A restaurant has two types of tables, rectangular
ones that can each seat 4 people and circular
tables that can each seat 8 people. If 144 people
are enough to fill all 30 tables at the restaurant,
how many rectangular tables does the restaurant
have?
A) 12
B) 16
C) 20
D) 24
Answer:
D) 24
Step-by-step explanation:
c + r = 30 Eq. 1
4r + 8c = 144 Eq. 2
r = rectangular tables
c = circular tables
From Eq. 1:
c = 30 - r Eq. 3
Replacing Eq. 3 in Eq. 2:
4r + 8(30-r) = 144
4r + (8*30 + 8*-r) = 144
4r + 240 - 8r = 144
-4r = 144 - 240
-4r = -96
r = -96/-4
r = 24
from Eq. 3
c = 30 - r
c = 30 - 24
c = 6
Check:
from Eq. 2
4r + 8c = 144
4*24 + 8*6 = 144
96 + 48 = 144
