Elsa is staining the wooden floor of a court. The court is in the shape of a rectangle. Its length is 43 feet and its width is 36 feet. Suppose each can of wood stain covers 172 square feet. How many cans will she need to cover the court?
Answer:
Step-by-step explanation:
find the area which is length divided by width then divide by 172 which is what each can covers. So, 43x36 =1548 and 1548/172 equals 9. So 9 is the answer
Solve the following system of equations. y + 5x = 30 2y = 5x + 15
Answer: Solve 2y-5x-30 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line 2y-5x-30 = 0 and calculate its properties
Step-by-step explanation:
Answer:
x = 3, y = 15
Step-by-step explanation:
Given the 2 equations
y + 5x = 30 → (1)
2y = 5x + 15 → (2)
Subtract 5x from both sides in (1)
y = 30 - 5x → (3)
Substitute y = 30 - 5x into (2)
2(30 - 5x) = 5x + 15 ← distribute left side
60 - 10x = 5x + 15 ( subtract 5x from both sides )
60 - 15x = 15 ( subtract 60 from both sides )
- 15x = - 45 ( divide both sides by - 15 )
x = 3
Substitute x = 3 into (3) for corresponding value of y
y = 30 - 5(3) = 30 - 15 = 15
Thus solution is x = 3, y = 15
how to solve?
x(8-4x)÷3?
A population of 40 rats living near a restaurant dumpster is growing at a monthly rate of 50%
Write an equation for this scenario
[(40 ÷ .5) Y] + 40
Parentheses are rat growth
Brackets are rat growth by how many years or just exclude that and the brackets if you don't need to know how many years are there are
The 40 is the amount of rats already there
Growth of rats plus the amount already there.
I'm probably wrong lol

Which of the following is equivalent to the inequality shown below?
4x + 0.9 ≥ 0.1
4x + 9 ≥ 1
4x + 9 ≥ 1
40x + 9 ≥ 1
40x + 9 ≥ 1
40x + 90 ≥ 10
40x + 90 ≥ 10
40x + 90 ≥ 1
Answer:
[tex]4x + 0.9 \geq 0.1[/tex] is equivalent to the inequality [tex]40x+9 \geq 1[/tex]
Step-by-step explanation:
Given inequality : [tex]4x + 0.9 \geq 0.1[/tex]
We are supposed to find Which of the following is equivalent to the inequality
[tex]4x + 0.9 \geq 0.1[/tex]
[tex]\Rightarrow 4x+\frac{9}{10} \geq \frac{1}{10}[/tex]
Multiply both sides by 10
[tex]\Rightarrow 4(10)x+\frac{9}{10}(10) \geq \frac{1}{10}(10)[/tex]
[tex]\Rightarrow 40x+9 \geq 1[/tex]
[tex]4x + 0.9 \geq 0.1[/tex] is equivalent to the inequality [tex]40x+9 \geq 1[/tex]
So, Option B is true
B) [tex]40x+9 \geq 1[/tex]
EXPLAIN HOW YOU GOT 3 AND 4 WITH STEPS PLS ITS URGENT
Answer:
2. x=25°
3. x=15°
4. x=26°
Step-by-step explanation:
For problem 2, we know the sum of the angles of a triangle is 180°. Also, supplementary angles are 180°.
30+20+x=180 [combine like terms]
50+x=180 [subtract both sides by 50]
x=130
Now that we have the missing angle, we can use that to solve for x.
2x+130=180 [subtract both sides by 130]
2x=50 [divide both sides by 2]
x=25°
Now, we know that x=25°.
For problem 3, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.
8x+25+2x+5=180 [combine like terms]
10x+30=180 [subtract both sides by 30]
10x=150 [divide both sides by 10]
x=15°
Now, we know that x=15°.
For problem 4, we know the sum of the angles of a triangle is 180°. This means, we add all the angles together and get 180°.
x+12+52+90=180 [combine like terms]
x+154=180 [subtract both sides by 154]
x=26°
Now, we know that x=26°.
Answer:
3. x = 5 4. x = 26
Step-by-step explanation:
3.
(2x + 5) + 8x + 25 = 180
10x +30 = 180
10x = 150
x = 15
4.
52 + 90 + x+12 = 180
52 + 90 + 12 = 142
x + 142 = 180
x = 180 - 154
x = 26

Answer:

Step-by-step explanation:
Suppose the cost of producing tires, t, is defined by C(t) = -0.45+2 + 12+ 450. Determine
which of the following intervals has the greatest average rate of change for the cost to
produce tires.
A
Between 2 and 4 tires
B
Between 46 and 48 tires
C
Between 12 and 14 tires
D
Between 22 and 24 tires
Answer:
Option (A)
Step-by-step explanation:
Function to represent the cost of producing 't' tires is,
C(t) = -0.45t² + 12t + 450
Since average rate of change of the function in the interval (a, b) is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
Following this rule,
Average rate of change in the interval (2, 4)
= [tex]\frac{C(4)-C(2)}{4-2}[/tex]
= [tex]\frac{490.8-472.2}{4-2}[/tex]
= 9.3
Average rate of change in the interval (46, 48)
= [tex]\frac{-10.8-49.8}{2}[/tex]
= -30.3
Average rate of change in the interval (12, 14)
= [tex]\frac{529.8-529.2}{2}[/tex]
= 0.3
Average rate of change in the interval (22, 24)
= [tex]\frac{478.8-496.2}{24-22}[/tex]
= --8.7
Average rate of change is greatest in the interval (2, 4)
Option (A) will be the answer.
Answer:
Average rate of change is greatest in the interval (46. 48)
Step-by-step explanation:
Average rate of change in the interval (2, 4)
= 9.3
Average rate of change in the interval (46, 48)
= -30.3
Average rate of change in the interval (12, 14)
= 0.3
Average rate of change in the interval (22, 24)
= --8.7

Step-by-step explanations:
A librarian wants to spend no more than $800 on some new desks and chairs for the library. The librarian decides to spend $320 on desks. If each chair costs $24, what is the maximum number of chairs the librarian can buy for the library and stay within the budget?
Answer:
20 chairs
Step-by-step explanation:
Since we are given the amount total budget and the total amount for the desks then the only variable missing is the maximum amount of chairs. This can be solved with the following equation in which s represents the number of chairs, and we simply solve for s.
800 = 320 + 24s ... subtract both sides by 300
500 = 24s ... divide both sides by 24
20.83 = s
Now we see that the maximum number of chairs that the librarian can buy is 20 because 21 would make her go over the budget and you cannot have 0.83 of a chair.
Answer:
The librarian can buy a maximum of 20 chairs to stay within the budget.
Step-by-step explanation:
The total budget is:
T = 800
From that budget, he spends 320 on desks (D), so he has the remaining amount to buy chairs (C):
[tex] C = 800 - 320 = 480 [/tex]
Since each chair costs 24, and he has 480 he can buy the following number of chairs:
[tex] n = \frac{C}{24} = \frac{480}{24} = 20 [/tex]
Therefore, the librarian can buy a maximum of 20 chairs to stay within the budget.
