Need help on number 5!
last year springfeild middle school had 620 students. this yearz it jas 559 students. To the nearest tenth, what is the precent decrease
The percentage decrease is 9.83%.
The previous year Springfield middle school students were 620. This year it is 559 students.
Here we have to find the decrease in the percentage of students from the previous year.
The decrease in the students = 620- 559
= 61
Percentage decrease = (decrease/number of students last year)× 100
= (61/ 620 )× 100
= 0.09838 ×100
= 9.83%
Therefore the percentage decrease in the number of students from the previous year is 9.83%

Bailey starts playing a game on her cell phone with the battery fully charged and plays until the phone battery dies. While playing the game the charge in Bailey's battery decreases by half a percent per minute. Write a function for the percent change in the battery while Bailey is playing the gane
The linear function for the percent change in the battery while Bailey is playing the gane is:
B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.
What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.For this problem, we have that:
The intercept is the initial battery, of 100.The slope is of -0.5, as the battery decays by 0.5% each minute.Hence the function is:
B(t) = 100 - 0.5t.
The battery will be of 0, when:
B(t) = 0.
100 - 0.5t = 0.
t = 100/0.5.
t = 200.
Hence the function is:
B(t) = 100 - 0.5t, 0 ≤ t ≤ 200.

According to the given statements,
The relationship between Distance and weight is Inversely proportional.
What is term Inversely proportional?If one variable rises, the other will fall; conversely, if one variable falls, the other will rise. These are inversely proportional variables or quantities. In other words, they are said to be inversely proportionate when an increase in one quantity causes a reduction in the other and vice versa.
According to the given values,
Here, distances are given as - (ft) 12, 24, 36, 48, 60
and Weight (Lb) are given as
7500,3750, 2500, 1875, 1500
When distance is small, the weight is high.
Distance ∝ 1/Weight
So, The relationship between distance and Height will be inversely proportional.

A plumber earns $75 for a repair job, plus an additional $45 per hour he works. On Tuesday, he completed 2 repair jobs and earned a total of at least $465.
Part A: Write an inequality that can be used to determine h, the numbers of hours the plumber worked Tuesday.
Answer:
He worked 7 hours
Step-by-step explanation:
X= Number of jobs, H= Hours worked T= Total money made
firstly we have to arrange this into a formula, which will allow you to insert any a value of one variable and find the other variable
this equation is 75x + 45h = T
from this question we know that he worked 2 jobs and made a total of 456$
Adding these into the equation we get:
(75*2) + 45h = 465
solving to find h by isolating the variable, the final answer will be
h = 7

4.99 x [tex]5 \frac{3}{4}[/tex] = 28.6925
Because of the kind of number (28.6925), you will have to round up.
To round up the number has to be a 5 or higher. Well, you have a 9 and then a 2. A 2 can't round up a 9, so you just end up discarding the 2 and the 5 at the end of the number.
Henceforth, you are left with 28.69.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction.
Find the lowest common denominator (LCD), convert each algebraic fraction to an equivalent fraction with the common denominator, and then combine each numerator to add or subtract algebraic fractions with distinct denominators. Reduce if you can.
Use the highest exponent of any common variable factor that has more than one exponent.
Add multiplied terms together to get a single fraction.

Total charge by company A for 80 sq.feet = 250+10(80)= $1050
Total charge by company B for 80 sq.feet = 90+12(90)=$1170
Let x be the no.of square feet for landscaping
Company A
Monthly consulting fee = $250
Cost of landscaping of 1 sq.feet = $10
Cost of landscaping of x sq.feet = $10x
So, Total charge by company A = 250+10x ---1
Company B
Monthly consulting fee = $90
Cost of landscaping of 1 sq.feet = $12
Cost of landscaping of x sq.feet = $12x
So, Total charge by company B = 90+12x ---2
Now we are supposed to find how many square feet of landscaping will the two companies charge the same amount
So, Equate 1 and 2
250+10x = 90+12x
160=2x
80=x
So, the two companies charge the same amount for 80 sq.feet
Total charge by company A for 80 sq.feet = 250+10(80)= $1050
Total charge by company B for 80 sq.feet = 90+12(90)=$1170
