Answer:
[tex] \frac{9}{2} = \frac{1}{3} hour[/tex]
[tex]x = \frac{3}{3} [/tex]
[tex]x = \frac{ \frac{9}{2} \times \frac{3}{3} }{ \frac{1}{3} } [/tex]
[tex] \frac{27}{6} \times \frac{3}{1} = \frac{27}{2} = 13 \frac{1}{2} [/tex]
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]

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.
I hope it helps you!

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

Members of Beta Club are selling candy bars to raise money. The club sponsor uses the following equation to calculate the amount of profit, "p" made from selling "n" candy bars. p = 2.50n - 200. How many candy bars must be sold to make a profit of 1500?
Answer:
680 candy bars must be sold
Step-by-step explanation:
2.5 times 680 equals 1700 that minus 200 is 1500.
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
What is the area of 10 length and a 3.5 width
Answer:
35
Step-by-step explanation:
The formula for area is length x width, so we multiply 10 x 3.5, which equals 35.

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
The graph of the parent function f(x) = x3 is translated to form g(x) = (x – 7)3 + 9. The point (0, 0) on the graph of f(x) corresponds to which point on the graph of g(x)?
(7, 9)
(–7, 9)
(9, 7)
(9, –7)
Answer:
c
Step-by-step explanation:
Using translation concepts, it is found that the point (0, 0) on the graph of f(x) corresponds to point (7, 9) on g(x).
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.
here, we have,
Considering the translations, the equivalent point is found as follows:
x -7 = 0 -> x =7.
y = 0 +9-> y = 9.
Hence the point (0, 0) on the graph of f(x) corresponds to point (7,9) on g(x).
