a. 100
b. 70
c. 40
d. There is not enough information given to determine the point of equilibrium.
Answer:
70 Forsure E2020
Step-by-step explanation:
The coordinates of the point of equilibrium are (-60, 110).
What is demand graph?A demand curve is graph that shows the relationship between the price of a good or service and the quantity demanded within a specified time frame.
Mathematically, we can write demand curve equation as -
Q = a - bP
where -
Q = linear demand curve
a = factors influencing demand besides price
b = slope
P = price
Given is to find the price at the point of equilibrium.
Equation for supply curve -
y = mx + c
y = {(25 - 20)/(10 - 0)}x + c
y = x/2 + 20
Equation for demand curve -
y = mx + c
y = {(10 - 20)/(40 - 30)}x + c
y = - x + 50
Point of equilibrium -
The point where demand equals to supply. We can write -
x/2 + 20 = - x + 50
x/2 - x = 30
- x/2 = 30
x = - 60
then -
y = 60 + 50
y = 110
Therefore, the coordinates of the point of equilibrium are (-60, 110).

What is the area of a circle with a radius of 20 inches ?
The area of a circle with a radius of 20 inches is 400π square inches, which is approximately 1256.64 square inches.
Explanation:The formula for finding the area of a circle is A = πr², where A is the area and r is the radius of the circle.
Given that the radius of the circle is 20 inches, we can substitute this value into the formula to find the area.
So, the area of the circle with a radius of 20 inches is A = π(20 inches)² = 400π square inches, which is approximately 1256.64 square inches.
1. What is the circumference of the given circle in terms of pi? radius= 14 in.
A. 14 pi in
B. 28 pi in
C 42 pi in
D 196 pi in
2. What is the circumference in terms of pi? Diameter= 6.6m.
A.16.2 pi m^2
B. 10.89 pi m^2
C. 21.78 pi m^2
D. 43.56 pi m^2
Answer:
1. B 2. B
Step-by-step explanation:
1. The formula for circumference is C= pi times diameter
Radius is half of diameter, so you'd multiply 14 times 2 which gives you 28. Since it's asking for it in pi, it'll be 28 pi.
2. I think instead of circumference, it's asking for area because if it was asking for circumference the answer would have been 6.6 pi, but that answer isn't there. So if it's asking for area, the formula is A= pi(r²) They gave the diameter instead. Remember, the radius is half of the diameter, so in order to get the radius, you'd divide 6.6 by 2 and get 3.3. Then, multiply 3.3 with the number itself, and you'll get 10.89.
Hope this helps!

A student concluded that the inequality −3+2y≤4x is equivalent to the inequality y≥2x+32, as shown below. Describe and correct the student’s error.
Answer:
[tex] -3 +2y \leq 4x[/tex]
[tex] 2y \leq 4x+3[/tex]
[tex] y \leq 2x + \frac{3}{2}[/tex]
And that's different from the claim of the student that:
[tex] y \geq 2x +\frac{3}{2}[/tex]
The error of the student is that he/she changes the sign of the inequality from [tex] \leq[/tex] to [tex]\geq[/tex] and that's not possible since we don't multiply both sides of the equation by -1
Step-by-step explanation:
For this case we have the following inequality:
[tex] -3 +2y \leq 4x[/tex]
We want to rewrite the last expression with y in the left and x in the right so we can begin adding 3 in both sides of the inequality and we got:
[tex] 2y \leq 4x+3[/tex]
Now we can divide both sides of the inequality by 2 and we got:
[tex] y \leq 2x + \frac{3}{2}[/tex]
And that's different from the claim of the student that:
[tex] y \geq 2x +\frac{3}{2}[/tex]
The error of the student is that he/she changes the sign of the inequality from [tex] \leq[/tex] to [tex]\geq[/tex] and that's not possible since we don't multiply both sides of the equation by -1
QUESTION 24 • 5 POINTS
Audrey can hike 6 miles on a trail in the same time that she can ride her bike 25 miles on a road. Her hiking speed is 9 miles
per hour slower than her riding speed. Find her riding speed. Round to the nearest tenth.
Answer:
Her riding speed is "11.84 mph".
Step-by-step explanation:
In order to solve this problem we will say that Audrey's riding speed is equal to "x" mph. Since her hiking speed is 9 mph less than her riding speed, then it is "x -9" mph. The average speed formula is given by:
speed = distance/time
Thefore the time to travel a certain distance with a certain speed is:
time = distance/speed
Her time to hike 6 miles is the same as her time to ride 25 miles, therefore:
ride time = hike time
25/x = 6/(x - 9)
25(x-9) = 6x
25x -225 = 6x
19x = 225
x = 225/19 = 11.84 mph
Her riding speed is "11.84 mph".
Alex wrote nine different positive digits on one red card and eight blue cards, only one digit per card. The product of all the digits on the blue cards is 72576.
What digit is written on the red card?
Answer: 5 is written on the red card.
Step-by-step explanation:
Given that the product of all the digits on the blue cards is 72576.
That is:
4! × 9 × 8 × 7 × 6
= 24 × 3024
= 72576
And the nine different positive digits will be 1 2 3 4 5 6 7 8 9
4! = 4 × 3 × 2 × 1
So, 5 is missing from the product of above number that gave 72576.
Therefore, 5 is the digit is written on the red card

What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
f(t) = -1/2t² + 2t + 6
Now, if ball hit the ground then f(t)=0
0 = -1/2t² + 2t + 6
-t² + 4t + 12=0
t² - 4t -12 = 0
t² - 6t + 2t -12 = 0
t(t- 6) + 2( t- 6)= 0
(t- 6) (t+ 2)=0
t= 6, -2.
Hence, the ball will take 6 seconds.

how much bigger is the area of a pizza with a diameter of 18 inches than the area of a pizza with a diameter of 10 inches
Answer:
approximately 3.24 times greater
Step-by-step explanation:
The formula for the area of a circle of radius r is A = πr². Because we are given the diameter here (not the radius), we substitute d/2 for r in the above formula, obtaining:
A = π(d/2)²
Case 1: A = π [18 in / 2]² = π(9 in)² = 81π in²
Case 2: A = π[10 in/2]² = π[5 in]² = 25π in²
Dividing 81π in² by 25π in² gives us the desired result:
The area of the larger pizza is 81/25 times the area of the smaller one, or approximately 3.24 times greater.

Step-by-step explanation:
1.Write the expression for when you translate the graph of y = x + 7 one unit to the left
2. Write the expression for when you translate the graph of y = 3x− 5 one unit to the right.
To translate y = x + 7 one unit to the left, the expression becomes y = x + 8. To move y = 3x - 5 one unit to the right, it becomes y = 3x - 8. The translation shifts the graph parallel to the x-axis while maintaining its shape.
To translate the graph of the function y = x + 7 one unit to the left, we substitute x with (x + 1) because adding to the independent variable moves the graph to the left.
Therefore, the translated expression would be y = (x + 1) + 7 which simplifies to y = x + 8.
Similarly, to translate the graph of the function y = 3x - 5 one unit to the right, we substitute x with (x - 1) because subtracting from the independent variable moves the graph to the right.
The translated expression is y = 3(x - 1) - 5, which simplifies to y = 3x - 3 - 5 or y = 3x - 8.
The process of translating graphs involves shifting each point parallel to the x-axis, either to the left or right, by the desired number of units without altering the shape of the graph.
Which simplified fraction is equal to 0.5ModifyingAbove 3 with bar? StartFraction 24 Over 45 EndFraction StartFraction 8 Over 15 EndFraction StartFraction 48 Over 90 EndFraction StartFraction 5 Over 9 EndFraction
Answer:
StartFraction 8 Over 15 EndFraction
Step-by-step explanation:
We want to represent 0.5333... as a fraction. Let's call x that fraction:
x = 0.5333
Then,
10x = 5.3333
100x = 53.333
100x - 10x = 53.333 - 5.3333
90x = 48
x = 48/90
dividing numerator and denominator by 6, we get:
(48/6) / (90/6) =8/15
Answer:
The simplified fraction is 1/8
The correct option is;
StartFraction 8 Over 15 EndFraction
Step-by-step explanation:
Here, we are given the simplified fraction result as [tex]0.5\bar3[/tex] which is the same as [tex]\frac{1}{2}+\frac{1}{30} =\frac{15+1}{30} =\frac{16}{30} =\frac{8}{15}[/tex]0.53333......
Therefore, to find the simplified fraction, we split the resultant value into the component parts as follows;
[tex]0.5\bar3[/tex] = 0.5 + 0.0[tex]\bar3[/tex]
We observe that the above equation is the same as [tex]\frac{1}{2}+\frac{1}{30}[/tex]
Hence, we simplify [tex]\frac{1}{2}+\frac{1}{30}[/tex] to arrive at
Therefore, the simplified fraction = 1/8.

Rewrite the function by completing the square.
f(x)=x^2+8x−29
f(x)=(x+__)^2+__
Answer:
(x + 4)² - 45
Step-by-step explanation:
Given
x² + 8x - 29
To complete the square
add/ subtract ( half the coefficient of the x- term)² to x² + 8x
f(x) = x² + 2(4)x + 16 - 16 - 29
= (x + 4)² - 45
The resulting function by completing the square is f(x) = (x+ 4)² - 45
Given the function
f(x) = x² + 8x - 29
The function can also be grouped like this:
f(x) = (x² + 8x) - 29
Completing the square of the function in parenthesis
f(x) = (x² + 8x) - 29
To do that, we will add the square of the half of the coefficient of x:
Coefficient of x = 8
half of Coefficient of x = 8/2 = 4
Squaring the result = 4² = 16
The function will then become:
f(x) = (x² + 8x + 16 - 16) - 29
f(x) = (x² + 8x + 16) - 16 - 29
f(x) = (x² + 8x + 16) - 45
Factorizing the function in bracket:
f(x) = (x+ 4)² - 45
Hence the resulting function by completing the square is f(x) = (x+ 4)² - 45
