A corn vendor at a farmer's makert was selling a bag of 8ears of corn for 2.56 Another Vendor was selling a bag of 12 for 4.32 Which bag is the better deal?

Answers

Answer 1

For both vendors, we need to obtain the price for an ear of corn to determine which bag is a better deal.

For the first vendor, we can obtain the cost of an ear of corn by dividing the price by the ears of corn, as follows:

$\begin{gathered} \frac{2.56}{8}=0.32 \\ 0.32\text{ per ear of corn} \end{gathered}$

As for the second vendor, we need to do exactly the same calculation:

$\begin{gathered} \frac{4.32}{12}=0.36 \\ 0.36\text{ per ear of corn} \end{gathered}$

Therefore, the better deal is the bag being sold by the first vendor

If a certain number x is multiplied by 6
It will be equal to four less than twice
the same number?

Answers

Answer: x= -1

Step-by-step explanation: 6x = 2x-4 4x= -4 and x=-1

From the given statement the unknown number is found to be - 1

The given statements can written in algebraic form as follows;

the unknown number = x

the number is multiplied by 6 = 6x

four less than twice the same number = 2x - 4

then, from the given statement the final equation equation becomes;

6x = 2x - 4

This unknown number can be solved by collecting similar terms together;

6x - 2x = -4

4x = -4

divide through by 4

$\frac{4x}{4} = \frac{-4}{4} \\\\x = -1$

Thus, the unknown number is - 1

In a pre algebra class containing 43 students, there are 4 freshman, 35 sophomores, and 4 juniors. what fraction of the class are sophomores

Answers

The fraction of the class that is sophomores is $35/43$.

The fraction of the class that is sophomores, divide the number of sophomores by the total number of students in the class.

Number of sophomores = 35

Total number of students = 43

Fraction of sophomores = (Number of sophomores)/(Total number of students Fraction of sophomores)

Fraction of sophomores $= 35 / 43$

Therefore, the fraction of the class that are sophomores is = $35/43$.

(ii) Suppose that 400g of the substance is present at to. How much will remain after 3 days?
(iii) What is the rate of change of the amount of the substance after 3 days?
(iv) After how many days will half of the original 400 g of the substance remain?

Answers

A function is a relationship between a few different inputs and an output, where each input can only lead to one possible outcome.

What is the chemical substance has a decay rate?

(i) The exponential function that models the decay of the substance is given by:

$N(t) = Noe^(-0.088t)$

(ii) If $400g$ of the substance is present at to, then $No = 400g$ . Therefore, the amount of the substance remaining after 3 days is:

$N(3) = 400e^(-0.0883) = 309.21g$ (rounded to two decimal places)

(iii) The rate of change of the amount of the substance after 3 days is given by:

$dN/dt = -0.088N(3) = -0.088309.21 = -27.21 g/day$ (rounded to two decimal places)

(iv) To find the number of days it takes for half of the original $400g$ of the substance to remain, we need to solve the equation:

$N(t) = 0.5No$

$0.5No = Noe^(-0.088t)$

$0.5 = e^(-0.088t)$

$ln(0.5) = -0.088t$

$t = ln(0.5)/(-0.088) = 7.89 days$ (rounded to two decimal places)

Therefore, after $7.89$ days, half of the original $400g$ of the substance will remain.

When we have two equations and two variables, we have a system of equations. To solve it we first need to manipulate and combine both equations in such a way that one of them contains only one variable. This can be through many means, by multiplying one equation by a constant in such a way that when both equations are added one variable gets canceled or by isolating one variable in one equation and using that value on the other.

In this case there is no need for any manipulation, because the variable "y" is "+3y" on the first equation and "-3y" on the second one. This means that if we add both, the "y" variable will be canceled. This is done below:

$\begin{gathered} \left\{ \begin{aligned}2x+3y=15 \\ x-3y=3\end{aligned}\right. \\ \end{gathered}$

Adding both equations:

$\begin{gathered} 2x\text{ + x +3y -3y = 15 + 3} \\ 3x\text{ = 18} \\ x\text{ = }\frac{18}{3} \\ x\text{ = 6} \end{gathered}$

We now use the calculated value for "x" in either equation to find y. We'll use the second equation.

$\begin{gathered} 6\text{ - 3y = 3} \\ -3y\text{ = 3 - 6} \\ -3y\text{ = -3} \\ y\text{ = }\frac{-3}{-3}\text{ = 1} \end{gathered}$

The answer to this system is x= 6 and y = 1.

If each friend gets the same number of pens;

Number of pens each friend get = Number of pens Kate has / Number of Kate's friends

= 63 / 9

= 7

Check:

Number of pens each friend get × Number of Kate's friends = Number of pens Kate has

7 × 9 = 63

2x + 7 = - 11 ( subtract 7 from both sides )

2x = - 18 ( divide both sides by 2 )

x = - 9

The answer is:

x = -9

Work/explanation:

The point of equations is to find the variable's value by isolating it step-by-step.

For this equation, the variable is x.

To isolate it, I will perform a few operations.

First, I will subtract 7 from each side:

$\sf{2x+7=-11}$

$\sf{2x=-11-7}$

$\sf{2x=-18}$

Divide each side by 2

$\sf{x=-9}$

Hence, x = -9.

Suppose 100 children were killed by guns in 1950. If the original statement is true, about how many
children were killed by guns in 1995?
children

Answers

Using an exponential function, it is found that if the original statement is true, $3.52 \times 10^{15}$ children were killed by guns in 1995.

Exponential function:

An increasing exponential function is modeled by:

$A(t) = A(0)(1 + r)^t$

In which:

A(0) is the initial value. r is the increase rate, as a decimal.

In this problem:

Researching on the internet, the original problem states that the number of children killed by guns has doubled each year since 1950, hence there is an increase of 100% every year, that is, $r = 1$.100 children were killed by guns in 1950, hence $A(0) = 100$.

Then:

$A(t) = A(0)(1 + r)^t$

$A(t) = 100(1 + 1)^t$

$A(t) = 100(2)^t$

1995 is 45 years after 1950, hence:

$A(45) = 100(2)^{45} = 3.52 \times 10^{15}$

If the original statement is true, $3.52 \times 10^{15}$ children were killed by guns in 1995.

The angles that are 118 degrees are ∠1 , ∠3, ∠5 and ∠7.

How to find angles in parallel lines?

When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate interior angles, alternate exterior angles, vertically opposite angles etc.

Therefore, let's find the angle relationship in the line and find the angles that are 118 degrees.

Hence,

∠3 = 180 - 62 = 118 degrees(angles on a straight line)

∠1 ≅ ∠3 (vertically opposite angles)

∠7 ≅ ∠3 (alternate interior angles)

∠5 ≅ ∠7 (vertically opposite angles)
