one school purchased 18 gallons of blue paint to decorate several of its classrooms. if each classroom needs 1 4/5 gallons of paint, then how many classrooms will get painted.
Answer:
18 gallons of paint could paint 10 classrooms.
Step-by-step explanation:
Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:
4/5 = 0.8
1 + 0.8 = 1.8
18 / 1.8 = 10
Therefore, 18 gallons of paint could paint 10 classrooms.
When is subtraction always the first operation done in an expression?
Answer:
When it is in parentheses.
Step-by-step explanation:
In PEMDAS, first is always parentheses, no matter what operation.
If it is subtraction, do that first.
hope this helped!
Answer:
the 3rd one
Step-by-step explanation:
this is only true when it is in perenthisis because when you do PEDMAS you go in that order. P (perenthisis) beng first. so TECHNECLY perenthisis is first, but the first actual MATH PROBLEM being done is subtraction.

The shorter diagonal of a rhombus measures 18cm. The side of the rhombus measures 41cm. Find the length of the longer diagonal.
Answer:
80 cm
Step-by-step explanation:
The diagonals divide the rhombus into four congruent triangles. The height of each triangle is 18/2 = 9, and the hypotenuse is 41. Using Pythagorean theorem, the width of each triangle is:
c² = a² + b²
41² = 9² + x²
x = 40
Therefore, the longer diagonal is 2×40 = 80.

i need help with this math side i just need b,c,d a =4x+2y=16
Answer:
Please check the explanatio.
Step-by-step explanation:
Solving Part b)
We know that the slope-intercept form of the equation line is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Given the equation
[tex]4x+2y=16[/tex]
Re-writing the equation in the slope-intercept form
[tex]4x+2y=16[/tex]
[tex]y=-2x+8[/tex]
Here, m=-2 and b=8
Thus, the equation in the slope-intercept form will be:
[tex]y=-2x+8[/tex]
Solving Part c)
As you sold two pounds of cheddar cheese.
i.e. y=2
substituting y=2 in the slope-intercept form of the line equation
[tex]y=-2x+8[/tex]
[tex]2=-2x+8[/tex]
Subtract 8 from both sides
[tex]-2x+8-8=2-8[/tex]
[tex]-2x=-6[/tex]
Divide both sides by -2
[tex]\frac{-2x}{-2}=\frac{-6}{-2}[/tex]
[tex]x=3[/tex]
You sold 3 pounds of swiss cheese.
Solving Part d)
[tex]y=-2x+8[/tex]
putting x=2.5 in the equation
[tex]y=-2x+8[/tex]
[tex]2=-2\left(2.5\right)+8[/tex]
[tex]2=3[/tex]
The sides are not equal
FALSE
Thus, x=2.5 does not make any sense in the context of the problem.

how did you transform each equation into a quadratic equation what concepts or principles did you employ
x (x + 4) = 5
x² + 4x = 5
x²+ x + (-5) = 0
(x+3)²+(t+3)²=9
x² + 6x + 9 + t² + 6t + 9 = 9
x² + t² + 6x + 6t + 18 + (-9) = 0
x² + t² + 6x + 6t + 9 = 0
x² + t² + 6(x + t) + 9 = 0
3/x + 4/2x = x - 1
6/2x + 4/2x = x - 1
10/2x = x - 1
10 = (x - 1) 2x
10 = 2x² - 2x
0 = 2x² + (-2x) + (-10)
How do you do b and c?
Answer:
b) 18
c) 80.78
Step-by-step explanation:
While we can solve this equation with separation of variables, it isn't necessary. The coffee is originally at 95°, and the ambient temperature is 18°. The top right graph is the only one that shows this trend.
As t approaches infinity, y approaches the ambient temperature of 18°.
yₙ₊₁ = yₙ + Δt F(tₙ, yₙ)
yₙ₊₁ = yₙ + 2 (-0.02 (yₙ − 18))
yₙ₊₁ = yₙ − 0.04 (yₙ − 18)
yₙ₊₁ = 0.96 yₙ + 0.72
When n=0:
y₁ = 0.96 y₀ + 0.72
y₁ = 0.96 (95) + 0.72
y₁ = 91.92
When n=1:
y₂ = 0.96 y₁ + 0.72
y₂ = 0.96 (91.92) + 0.72
y₂ = 88.96
When n=2:
y₃ = 0.96 y₂ + 0.72
y₃ = 0.96 (88.96) + 0.72
y₃ = 86.12
When n=3:
y₄ = 0.96 y₃ + 0.72
y₄ = 0.96 (86.12) + 0.72
y₄ = 83.40
When n=4:
y₅ = 0.96 y₄ + 0.72
y₅ = 0.96 (83.40) + 0.72
y₅ = 80.78

The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially. How many grams of the substance are left after 300 years?
Answer:
There are 2,000 grams left after 300 years.
Step-by-step explanation:
Giving the following information:
The half-life of a radioactive substance is 200 years. There are 8000 grams of the substance initially.
First, we need to calculate the reduction of the substance each year:
Yearly reduction= 8,000/400= 20 grams per year
Now, for 300 years:
300 year reduction= 20*300= 6,000
There are 2,000 grams left after 300 years.

Monica and her parents spent $170 on new swimsuits. Monica’s swimsuit cost $35. Her mom’s swimsuit cost twice as much as Monica’s. How much did her dad’s swimsuit cost?
━━━━━━━☆☆━━━━━━━
▹ Answer
Her dad's swimsuit costs $65.
▹ Step-by-Step Explanation
Since Monica's swimsuit is $35, we will subtract that from the total amount spent, $170.
$170 - $35 = $135
Since Monica's mom's swimsuit costs 2x Monica's we will multiply 35 * 2:
$35* 2 = $70
We will now add Monica's cost and her moms' cost:
$35 + $70 = $105
To find Monica's dads' cost, we will subtract 105 from 170:
$170 - $105 = $65
Her dad's swimsuit costs $65.
Hope this helps!

Two system of equations 2y =14-2x and y=-x + 7 is graphed. What is the solution to the system of equations
To solve this system, we will use the graphing method.
Based on the graph shown below, we can conclude that this system has infinite solutions, because they are the same line.
Answer:
Infinitely many solutionsStep-by-step explanation:
Given equations
2y =14-2x and y= -x + 7Rewriting the first equation
2y = 14 - 2x2y = -2x + 14y = -x + 7As we see it is same as the second equation. So same two lines, overlapping when graphed and the system has infinitely many solutions
Mia went into a fair with $55.75 in her pocket. She bought a hot dog and drink for $2.975 each and then wanted to spend the rest of her money on rids tickets, which costs $0.95 each. Write an inequality to represent the total where r is the number of tickets purchased.
What is the maximum number of tickets mia can buy or purchesed_______?
Graphs how many rides tickets can mia buy without going over her budget.?
Answer: Maximum tickets she can buy is 52
Step-by-step explanation:
After she bought the fries and drinks she was left with $49.81. If she spent the rest of her money on rides/tickets for the rides then she bought 52 tickets to be exact. 0.95x52=49.40

Answer:
a.(-1,8), (2,9) b. (2,0) (3,5)
Step-by-step explanation:
a.
for (-4, 7) slope is [tex]\frac{1}{3}[/tex]
slope is m=rise /run =rise 1/run3 so to go to the next point
from (-4,7)
rise 1 so now you are at (-4,8) and run 3 and you are at (-1,8)
from (-1,8)
rise 1 to (-1, 9) and run 3 to (2,9)
b
(1,-5) slope is [tex]\frac{5}{1}[/tex]
from (1,-5) rise 5 to (1,0) and run 1 to (2,0)
from (2,0) rise 5 to (2,5) and run 1 to (3,5)

Answer: b, 12
explanation: combine -3/2 * x and u get -3/2x. then isolate the variable by doing the inverse of subtraction on both sides. (add 9 on both sides). then do the inverse of multiplication on both sides. (divide by -3/2 on both sides)

Avram borrows $14,500 at 5.4% simple interest to open a small business. His bank allows him 9 years to pay back the loan. How much simple interest will Avram have to pay on the loan?
Answer:
Avram will have to pay $7,047 simple interest
Step-by-step explanation:
Simple Interest
Definition: Interest calculated on the original principal only of a loan or on the balance of an account.
Unlike compound interest where the interest earned in the compounding periods is added to the new principal, simple interest only considers the principal to calculate the interest.
The interest earned is calculated as follows:
I=A.r.t
Where:
I = Interest
P = initial principal balance
r = interest rate
t = time
Avram has a principal of P=$14,500 at a simple rate of r=5.4%=0.054 for t=9 years, thus:
I=14,500*0.054*9=7,047
I=$7,047
Avram will have to pay $7,047 simple interest
Answer:
$7,047 simple interest
