Answer:
Step-by-step explanation:
50,000 * 60%= 30,000
If Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
Given that, Engineer Sandy earns a salary of $50000 per year. If Sandy spends each year 60% of her income on expenses,
We have to find the amount Sandy has to spend on expenses,
The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.
The amount spend on the expenses is,
Expenses = 60% of the salary
Expenses =60/100 × $50000
Expenses = 30,000
Thus, if Sandy receives a $50000 salary for working as an engineer. If Sandy spends 60% of her salary on expenses each year, then Sandy spends $30,000 on expenses.

PROVE ALGEBRAICALLY THAT 0.5 = 5/9
Answer:
See Below.
Step-by-step explanation:
Let:
[tex]0.\overline{5}=n[/tex]
If we multiply both sides by 10, we get:
[tex]5.\overline{5}=10n[/tex]
Now, we will subtract n from both sides:
[tex]5.\overline{5}-n=10n-n[/tex]
On the left, we can replace the n:
[tex]5.\overline{5}-.\overline{5}=10n-n[/tex]
Subtract:
[tex]5=9n[/tex]
Divide both sides by 9:
[tex]n=\frac{5}{9}[/tex]
Hence:
[tex]n=0.\overline{5}=\frac{5}{9}[/tex]

One jug of powdered plant food treats an area of 140 square feet of flowers. How many jugs would be needed to treat an area of 175 square feet?
Use a graph plz!
Answer:
Step-by-step explanation:
Let [tex]n[/tex] and [tex]A[/tex] the number of jugs and the area of flowers, measured in jugs and square feet. We assume that exists a direct relationship between both variables. That is:
[tex]A \propto n[/tex]
[tex]A = k\cdot n[/tex] (1)
Where [tex]k[/tex] is the proportionality constant, measured in square feet per jug.
If we know that [tex]n = 1\,jug[/tex] and [tex]A = 140\,ft^{2}[/tex], then the proportionality constant is:
[tex]k = \frac{A}{n}[/tex]
[tex]k = 140\,\frac{ft^{2}}{jug}[/tex]
Then, the relationship between both variables is represented by:
[tex]A = 140\cdot n[/tex]
If we know that [tex]A = 175\,ft^{2}[/tex], then the minimum number of jugs needed to treat the area is:
[tex]n = \frac{175\,ft^{2}}{140\,\frac{ft^{2}}{jug} }[/tex]
[tex]n = 1.25\,jugs[/tex]
Since jugs represents a discrete set, then we round this number up to the next integer. In other words, we find that 2 jugs are needed to treat an area of 175 square feet.
Lastly, we present a graph to estimate the minimum value of jugs:
Gianna is working two summer jobs, making $12 per hour washing cars and $8 per
hour landscaping. Last week Gianna worked a total of 5 hours and earned a total of
$48. Graphically solve a system of equations in order to determine the number of
hours Gianna worked washing cars last week, x, and the number of hours Gianna
worked landscaping last week, y.
Answer:
x + y = 5
12x + 8y = 48
x = -y + 5
12(-y + 5) + 8y = 48
-12y + 60 + 8y = 48
-4y + 60 = 48
-4y = -12
y = 3
x + 3 = 5
x = 2
12(2) + 8(3) = 48
24 + 24 = 48
x = 2 hours of washing cars
y = 3 hours of landscaping
Hope this helps!!

The value of x and y should be 2 and 3.
Calculation of the value of x and y:
Since Gianna is working two summer jobs, making $12 per hour washing cars and $8 per hour landscaping. Last week Gianna worked a total of 5 hours and earned a total of $48.
So here the equation should be
x + y = 5
12x + 8y = 48
we can write as
x = -y + 5
So,
12(-y + 5) + 8y = 48
-12y + 60 + 8y = 48
-4y + 60 = 48
-4y = -12
y = 3
Now
x + 3 = 5
x = 2
Therefore, The value of x and y should be 2 and 3.

Find the equation of the line with slope =10 and passing through (-6,7). Write your equation in point slope form AND slope intercept forms.
Answer:
The equation of the line in the slope-point form is y - 7 = 10(x + 6)
The equation of the line in the slope-intercept form is y = 10x + 67
Step-by-step explanation:
The slope-point form of the linear equation is y - y1 = m(x - x1), where
m is the slope(x1, y1) are the point lies on the lineThe slope-intercept form of the linear equation is y = m x + b, where
m is the slopeb is the y-intercept∵ The slope of the line is 10
∴ m = 10
∵ The line passes through the point (-6, 7)
∴ x1 = -6 and y = 7
→ Substitute them in the slope-point form above
∵ y - 7 = 10(x - -6)
∵ (-)(-) = (+)
∴ y - 7 = 10(x + 6)
∴ The equation of the line in the slope-point form is y - 7 = 10(x + 6)
→ Substitute m in the slope-intercept form
∵ y = 10x + b
→ To find b substitute x by -6 and y by 7 in the equation
∵ 7 = 10(-6) + b
∴ 7 = -60 + b
→ Add 60 to both sides to find b
∴ 67 = b
→ Substitute the value of b in the equation
∴ y = 10x + 67
∴ The equation of the line in the slope-intercept form is y = 10x + 67
A math tutor decides to increase his wage by 11%. What expression shows his new wage after the 11%
Answer:
1.11w
Step-by-step explanation:
Let initial wage = w
Percentage increase in wage = 11%
Using the relation :
New Amount = initial * (1 + % increase)
New Amount = w * (1 + 0.11)
New amount = w * (1.11)
New amount = 1.11w

James asks 60 pupils which drink they liked best from cola milk and water 32 boys were in the survey 12 of the boys said they liked cola the best 4 boys and 9 girls liked water the best 21 pupils said they liked milk altogether How may students altogether liked cola the best
Answer:
Students altogether liked cola the best 26
Step-by-step explanation:
Total no of pupils = 60
Boys = 32
girls = 28
we will make a table
Gender cola milk water total
Boys 12 4 32
Girls 9 28
we can find the missing numbers
Let x be for milk
In boys 12 + x + 4 = 32
x = 16
In girls
as 21 liked milk altogether
so girls = 21 - 16 = 5
Gender cola milk water total
Boys 12 16 4 32
Girls 5 9 28
For cola let y
in girls
y + 5 + 9 = 28
y = 14
Gender cola milk water total
Boys 12 16 4 32
Girls 14 5 9 28
Altogether cola = 14 + 12 = 26

Yesterday,
grace drove 35 1/2used
gallons 1 1/4 of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallon is 33.75. 33.75 as a fraction 135/75
Step-by-step explanation:
35.5 divided by 1.75 is 33.75
33.75 as a fraction is 135.75 which is an improper fraction
So you have to divide the numerator by the denominator
135 divided by 75 is 1.8 as a decimal
Answer:
28.4
Step-by-step explanation:
35 1/2 miles over 1 1/4 gallons of gasoline. 1 1/4 converted into an improper fraction is 5/4, so you multiply the numerator and denominator by 5/4. You need to multiply by 5/4 because you need to get to miles per gallon, which equals to 1. (A fraction multiplied by its reciprocal will always equal 1) once you've multiplied the numerator and denominator by the reciprocal, your answer will be 28.4 - hope this helped!

Discuss the difference between fixed expenses and variable expenses as they relate to a budget
Answer:
Fixed expences are expences that don't change month-to-month, whereas variable expences are things that are needing to budgeted for every month, but may vary a bit and are therefor usually estimated on a budget.
Step-by-step explanation:
For example, rent would be a fixed expense because you know it will be X amount due on the same day every month. Food, on the other hand, would be a variable expense because it likely won't be the same amount month-to-month.
Answer:
Fixed expenses are expenses that stay the same for a person or a business. An example of a fixed expense is rent/mortgage. This expense doesn't change if you are only using the building for 2 weeks or the entire month, it's a set rate. A variable expense is an expense that changes like an electric bill, it varies based on the month and usage. When you budget, you can easily budget for your fixed expenses but you need to allow some room in your budget for expenses that change.
