The number of the 1(3/4) inch blocks will be 34 out of the 5 feet of stock.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that 1 3/4-inch long machine bolt blanks can be cut from a 5-foot length of the stock. The number of the blocks will be calculated as below:-
Number = 5 foot / ( 1(3/4)
Number = 60 / ( 7/4)
Number = 34.2
Therefore, the number of the 1(3/4) inch blocks will be 34.

calculate the percent of population each situation represents b) 90 out of a population of 450 people
The percent of population in the situation is 20 %.
Percentage means a number or a ratio represented in the form of fractions of 100. It is represented using the percentage sign ‘%’. In other words, the percentage is defined as how much of one quantity is made by another quantity and it is evaluated in terms of 100.
We have to find the percentage of population 90 out of a population of 450 people represents.
We know that, the formula for percentage will be:-
(Given people/ Total people)*100
Here,
Given people = 90
Total people = 450
Hence, the percentage will be :-
= (90/450)*100 = (1/5)*100 = 20 % .

much will 10 packs of stylus pens cost at this price?
The cost of ten pack of stylus pen is $(50/3).
This problem can be solved by unitary method and can be understood by the following process.
In this method we have to determine the cost of a unit of product and then the total amount by multiplying the unit cost by the desired quantity what we want.
Here, it is given that three packs of stylus pen costs $5.
Cost of one pack of stylus pen = $ 5/3
Therefore cost of 10 packs of stylus pen = $(5/3)*10

Of the students that stated they would be going to Camp Redwood, 20% did not go to camp. Of the students that stated they would be going to Camp Kern, 15% did not go to camp. How many more students went to Camp Kern than Camp Redwood?
If the students that stated they would be going to Camp Redwood, 20 percentage did not go to camp and the students that stated they would be going to Camp Kern, 15 percentage did not go to camp, then 51 more students went to camp kern than camp redwood
The total number of students in Camp redwood =170
Number of students who didn't attend the camp redwood = 170×(20/100)
=34 students
Number of students who went to camp redwood =170-34
=136 students
Total number of students in Kern camp = 220
Number of students who didn't attend the camp Kern=220×(15/100)

a) Work out an equation connecting y and x.
b) Work out the value of y when x = 12.
Answer: Our required equation would be
Step-by-step explanation:
Since we have given that
y=30, when x = 6.
As there is direct proportion between x and y.
so, it becomes,
So, the equation connecting y and x would be
When we put the value of k, we get that
Hence, our required equation would be y=5x
Solve system of equations.
y=2 x+1
y=3 x
The system of equations involving y = 2x + 1 and y = 3x has the solution written as an ordered pair (1 , 3).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
y = 2x + 1 (equation 1)
y = 3x (equation 2)
Since both equations are in the form of y in terms of x and some constant, substitute the second equation to the first equation.
y = 2x + 1 (equation 1)
3x = 2x + 1
Combining the all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
3x - 2x = 1
x = 1
Substituting the value of x in the second equation,
y = 3x (equation 2)
y = 3(1)
y = 3
Writing it as an ordered pair, we got (1 , 3) as the solution of the system of equations involving y = 2x + 1 and y = 3x.

The cost of a ticket to the circus is $23.00 for children and $47.00 for adults. on a certain day, attendance at the circus was 500 and the total gate revenue was $18,700. how many children and how many adults bought tickets?
Answer:
200 children and 300 adults
Step-by-step explanation:
No. of children = c
No. of adults = a
EQUATION 1: a + c = 500
EQUATION 2 : 23c + 47a = 18700
a = 500 - c
23c + 47(500 - c) = 18700
23c + 23500 - 47c = 18700
-24c = 18700 - 23500
-24c = -4800
-4800/-24 = c
c = 200
a = 500 - 200
a = 300

What is variability?The term "variability" (also known as "spread" or "dispersion") describes how dispersed a set of data is. You may use statistics to compare your data to other sets of data by using the term "variability" to indicate how much the data sets differ from one another.
In a data collection, there are four major approaches to describe variability:
Range: The difference between your smallest and largest piece in the set called the range.Interquartile range: The interquartile range is virtually identical to the range, with the exception that you only give the value for the "middle fifty" as opposed to the range for the whole data set.Variance: A data set's variance offers you a general indication of how evenly distributed your data is.Standard deviation: You may determine how closely your data is grouped around the mean using the standard deviation (the average).To learn more about variability , visit:
