Solve the formula C = td for d.
Answer:
d = C /t
Step-by-step explanation:
C = td
We want to isolate d, so divide each side by t
C/t = td/t
C/t = d
d = C /t
Answer: c/d = t
Since d is being multiplied by t, to get d by itself we simply divide both sides of the equation by t and we have c/d = t which is our final answer.

which of the following are solutions to the quadratic equation? Check all that apply 2x^2+14x-4=-x^2+3x
Answer:
[tex]x_1=-4\\\\x_2=\frac{1}{3}[/tex]
Step-by-step explanation:
Given the quadratic equation:
[tex]2x^2+14x-4=-x^2+3x[/tex]
You can follow these steps in order to solve it:
- Make the equation equal to 0:
[tex]2x^2+14x-4+x^2-3x=0[/tex]
- Now, add the like terms:
[tex]3x^2+11x-4=0[/tex]
- Finally, apply the Quadratic formula ([tex]x=\frac{-b\±\sqrt{b^2-4ac} }{2a}[/tex]):
In this case we know that:
[tex]a=3\\b=11\\c=-4[/tex]
Therefore, substituting values into the Quadratic formula and evaluating, we get:
[tex]x=\frac{-11\±\sqrt{11^2-4(3)(-4)} }{2(3)}\\\\x_1=-4\\\\x_2=\frac{1}{3}[/tex]
To find the solutions to the quadratic equation 2x^2+14x-4=-x^2+3x, we need to rearrange the equation and use the quadratic formula.
Explanation:The quadratic equation is 2x^2+14x-4=-x^2+3x. To find the solutions, we need to rearrange the equation in the form ax^2 + bx + c = 0. Combining like terms, we get 3x^2 + 11x - 4 = 0. Now we can use the quadratic formula to find the solutions:
x = (-b ± √(b^2 - 4ac)) / 2a
Plugging in the values a = 3, b = 11, and c = -4 into the formula, we can calculate the solutions.

What is the radical form of the expression 4 2/3 ?
Answer:
∛4²
Step-by-step explanation:
A fraction exponent can be represented using a radical. The base number is the number in the radical. The numerator of the fraction is the exponent inside the radical. The denominator is the type of radical.
To write an exponent in radical form , the denominator, or index goes in front of the radical, and the numerator goes inside of the radical. We raise the base to the power of the numerator
4 2/3
∛4².
The radical form of 4 2/3 is the cube root of 4 squared, denoted as √(4^2).
Explanation:The radical form of the expression 4 2/3 means expressing the number as a radical, which refers to roots of numbers. In this case, the number 2/3 is the exponent in fractional form. To convert this into a radical, the numerator indicates the power and the denominator indicates the root. Therefore, 42/3 can be expressed as the cube root of 4 squared. The cube root is denoted by the radical symbol √ with a small three above or to the left of the radical. Thus, 42/3 = √(42).

A map uses a scale where 1 inch = 3 miles. The actual distance between City A and City B is 231 miles. What is the distance between the cities on the map?
I got 693, but I am not sure I really understand the question.
Answer:
77 inches
Step-by-step explanation:
Given
1 inch = 3 miles in map
We are also given the actual distance between City A and City B = 231 miles.
In order to get the distance in inches = Distance between City A and City B in miles/ 3
We are dividing the distance by 3 to get the distance in inches.
So,
Distance on map = 231/3
= 77 inches
Answer: 77 inches.
Step-by-step explanation:
You know that this map uses this scale:
[tex]1in=3mi[/tex]
This means that 1 inch in the map represents 3 miles.
In this case, you know that the actual distance between City A and City B is 231 miles, then, to find the distance between the cities on the map, you can set up de following proportion:
[tex]\frac{1in}{3mi}=\frac{x}{231mi}[/tex]
Now, you need to solve for "x":
[tex](231mi)(\frac{1in}{3mi})=x\\\\x=77in[/tex]
Which function in vertex form is equivalent to f(x) = 4 + x2 – 2x?
f(x) = (x – 1)2 + 3
f(x) = (x – 1)2 + 5
f(x) = (x + 1)2 + 3
f(x) = (x + 1)2 + 5
Answer:
option A
f(x) = (x – 1)2 + 3
Step-by-step explanation:
Given in the question a function,
f(x) = 4 + x² – 2x
Step 1f(x) = 4 + x² – 2x
here a = 1
b = -2
c = 4
Step 2x = -b/2a
h = -(-2)/2(1)
h = 2/2
h = 1
Step 3
Find k
k = 4 + 1² – 2(1)
k = 3
Step 4
To convert a quadratic from y = ax² + bx + c form to vertex form,
y = a(x - h)²+ k
y = 1(x - 1)² + 3
y = (x - 1)² + 3
ANSWER
The vertex form is
[tex]f(x) = {(x - 1)}^{2} + 3[/tex]
EXPLANATION
The given function is
[tex]f(x) = 4 + {x}^{2} - 2x[/tex]
This is the same as:
[tex]f(x) = {x}^{2} - 2x + 4[/tex]
We add and subtract the square of half the coefficient of x.
[tex]f(x) = {x}^{2} - 2x + {( -1 )}^{2} - {( -1 )}^{2} + 4[/tex]
[tex]f(x) = {x}^{2} - 2x + 1 - 1 + 4[/tex]
The first three term is a perfect square trinomial:
[tex]f(x) = {(x - 1)}^{2} + 3[/tex]
The vertex form is
[tex]f(x) = {(x - 1)}^{2} + 3[/tex]
P(A)= .50 P(B)=.80 P(A and B)=.20 what is P(B/A)
Answer:
Final answer is [tex]P(B|A)=0.40[/tex].
Step-by-step explanation:
Given that P(A)= .50, P(B)=.80 , and P(A and B)=.20.

Two cell phone companies have different rate plans. Runfast has monthly charges $8 plus $8 per gig of
data. B A &D’s monthly charge is $15 plus $4 per gig of data. Your task is to determine under what
circumstances each company has the better pricing. You will derive and solve a set of equations, graph
those equations, and evaluate the meanings for these events. Don’t worry; I have a series of questions
to guide you through the process. Good luck!
1. Determine the equation for the monthly charges for Runfast and BA&D. (2 points)
Runfast= ______________________
BA&D=________________________
2. Use your mathematical skill to solve this system of equations using the substitution method. (4
points)
Show your work here:
Answer:
Part 1) The equation for the monthly charges for Runfast is [tex]y=8x+8[/tex] and for BA&D is [tex]y=4x+15[/tex]
Part 2) The solution of the system of equations is the point (1.75.22)
Step-by-step explanation:
Let
x -----> the number of gig of data
y -----> the total monthly charges
we know that
Runfast Company
[tex]y=8x+8[/tex] -----> equation A
BA&D Company
[tex]y=4x+15[/tex] -----> equation B
Part 2) Use your mathematical skill to solve this system of equations using the substitution method
we have
[tex]y=8x+8[/tex] -----> equation A
[tex]y=4x+15[/tex] -----> equation B
Substitute equation B in equation A and solve for x
[tex]4x+15=8x+8[/tex]
[tex]8x-4x=15-8[/tex]
[tex]4x=7[/tex]
[tex]x=1.75\ Gb[/tex]
Find the value of y
[tex]y=8(1.75)+8=\$22[/tex]
so
The solution is the point (1.75.22)
That means
For the number of gig equal to 1.75 the monthly charge is equal to $22 in both company's
therefore
For a number of gigs less than 1.75 the company Runfast has the better pricing, while for a number of gigs greater than 1.75 the company BA&D has the better pricing

B. no solution
C. { x : 5 < x < 7 }
D. { x : x < 5 or x > 7 }
Answer:
the answer is D
Step-by-step explanation:
To solve the inequalities 3x + 1 ≥ 8 and 10x ≤ 15, we find that no x can satisfy both inequalities simultaneously. Thus, the solution set is empty and the correct answer is B. No solution.
Solving the System of Inequalities
We need to find the solution set for the system: 3x + 1 ≥ 8 and 10x ≤ 15.
Solve the first inequality:3x + 1 ≥ 8
Subtract 1 from both sides: 3x ≥ 7
Divide by 3: x ≥ 7/3 x ≥ 2.33
Solve the second inequality:10x ≤ 15
Divide by 10: x ≤ 1.5
Combine the two results:For the two conditions x ≥ 2.33 and x ≤ 1.5 to both be true, there is no number x that satisfies both.
Therefore, the solution set is empty.
The correct answer is B. No solution.

Can anyone please show me the steps of solving this equation
Answer:
-6x + 15 = - 69 which x = 14
Step-by-step explanation:
You cannot solve this equation. There is no equal sign anywhere. Either you mean
-6x = 15 in which case the answer is
-6x/-6 = 15/-6
x = - 2 1/2 or x= - 2.5
or you mean that you use the distributive property
- 3(2x + 5)
You may have left something out of this.
-6x + 15 = - 69
You can do it now that you have the complete equation. But you need the entire equation before you can answer the question.
Subtract - 15 from both sides.
-6x + 15 - 15 = -69 - 15
-6x = - 84
Divide by - 6
-6x/-6 = - 84/-6
x = 14
But what you want is
-6x + 15
-6*14 + 15
-84 + 15
-69
-6x + 15 = - 69
when x = 14 which is usually what you are asked.
what is the quotient in polynomial form ?
Answer:
Any quotient of polynomials a(x)/b(x) can be written as q(x)+r(x)/b(x), where the degree of r(x) is less than the degree of b(x). For example, (x²-3x+5)/(x-1) can be written as x-2+3/(x-1). This latter form can be more useful for many problems that involve polynomials.
Step-by-step explanation:
The quotient in polynomial division refers to the result of dividing one polynomial by another. When a polynomial S is divided by a polynomial P, the result is a quotient Q of a degree less than P. The quotient Q represents a rational function when it is derived from the division of two polynomials.
In terms of algebra, let's consider a polynomial P of degree n, and we divide another polynomial S with a degree less than 2n by P. The result is a quotient Q and a remainder R, both of which are polynomials and Q has a degree less than n. If P(x) has a degree higher than Q(x), one can use the method of long division to find the quotient. This quotient, Q, alongside the remainder, R, conforms to the relation S(x) = P(x)\Q(x) + R, where Q and R are of lesser degrees than P.
When dealing with rational functions, we often find ourselves in positions of evaluating expressions formed by dividing polynomials. These functions are called rational functions, which are essentially the quotient of two polynomials. Applying the quotient rule can simplify differentiable polynomial functions and is useful when finding limits or derivatives in calculus.

the first ferris wheel was built in 1893 in chicago. It’s diameter was 250 feet. How many feet did the ferris wheel rotate with one complete turn?
Answer:
about 785.4
Step-by-step explanation:
The circumference of a circle is pi times the diameter:
C = πd
C = π·(250 ft) ≈ 785.4 ft
_____
Most scientific or graphing calculators have the value of π built in. If yours doesn't, a value good for at least 6 significant figures is the ratio 355/113.
The ferris wheel rotates approximately 785 feet in one complete turn. This was calculated using the circumference formula, 2πr, with the radius derived from the given diameter of 250 feet.
Explanation:To solve this problem, we need to determine the circumference of the Ferris wheel as that would be equivalent to the distance the ferris wheel rotated in one complete turn. The formula to calculate the circumference of a circle (or ferris wheel in this case) is 2πr (2 times pi times the radius), where 'r' is the radius of the circle. However, since we're given the diameter of the Ferris wheel as 250 feet, we know that the radius 'r' would be half of the diameter. That would imply that the radius in this case is 250/2 = 125 feet. So, using the aforementioned formula, the circumference would therefore be 2 × π × 125, or approximately 785 feet. Therefore, with each complete turn, the Ferris wheel would rotate by about 785 feet.

Tomas ran a Lucky Dip stall.
LUCKY DIP
Tickets 50p
Tickets ending 00 win £12
Tickets ending 5 win £1.50
There were 750 tickets, numbered 1 to 750
Tomas sold all the winning tickets, and some of the losing tickets.
He made a profit of £163
How many losing tickets did he sell?
Answer:
637
Step-by-step explanation:
Ticket ending 00= £12 * 7 = £84
Tickets ending 5 = £1.5 * 75 = £112.5
£84+£112.5=£196.5
Price money + Profit: £196.5+£163= 356
356/£0.5 = 719 total tickets sold
719- 82 (WINNING TICKETS) = 637 losing tickets sold
Tomas made £232.5 from the winning tickets. Subtracting his profit of £163, we see he made £69.5 from the losing tickets. At a price of £0.5 per ticket, that means he sold 139 losing tickets.
Explanation:First, calculate the total amount Tomas made by selling all the winning tickets. There are ten tickets that end in '00' between 1 and 750, each valued at £12, i.e., £120. There are 75 tickets that end in '5' between 1 and 750, each valued at £1.50, i.e., total of £112.50. So, the total income from these tickets is £120 + £112.50 = £232.5.
Then, subtract Tomas's profit from the total income of the winning tickets to get the total revenue from the losing tickets. So, £232.5 - £163 = £69.5. Given each ticket costs 50p or £0.5, divide £69.5 by £0.5 to find the number of losing tickets sold. That is, £69.5/£0.5 = 139. Thus, Tomas sold 139 losing tickets.

When class 11Y1 found that their favourite teacher, Mr Musson, was leaving they decided to organise a party for him. Lewis, one of the class members, wants to buy 38 cartons of juice. He can buy a single carton of juice for 45p. He can buy a pack of 4 cartons for £1.56 Lewis buys all the cartons he needs for the least possible amount of money. How much did he spend?
By buying 9 packs of 4 cartons and 2 single cartons, Lewis was able to spend the least amount of money to get the 38 cartons he needed. The total cost was £14.94.
Explanation:The subject of this question is mathematics, specifically cost optimization and arithmetic. Lewis can buy single carton of juice for 45p or a pack of 4 cartons for £1.56. The goal is to minimize the cost. First, Lewis can start by buying packs of 4. The number of 4-carton packs he can buy is 38 divided by 4 which gives you 9 packs that include 36 cartons. He then needs to buy 2 more single cartons to reach 38. So, the total cost is 9 packs times £1.56/pack plus 2 single cartons times 45p/carton. Doing the arithmetic:
Cost of Packs: 9 packs x £1.56/pack = £14.04Cost of Single Cartons: 2 cartons x 45p/carton = 90pConvert 90p to pounds that is £0.90. Adding both gives £14.94. Therefore, Lewis spent a total of £14.94 on juice cartons.
