The ratio of acres of barley to acres of corn at a small farm is 3 : 4. Find the equivalent ratio that uses 18 acres of barley.
Answer:
24 acres of corn, so the equivalent ratio is 18 acres of barley to 24 acres of corn.
Step-by-step explanation:
18 ÷ 3 = 6, so multiply 4 × 6 to obtain 24 acres of corn.
Alternately: Let c be the number of acres of corn. Set up and solve this proportion.
[tex] \frac{3}{4} = \frac{18}{c} [/tex]
[tex]3c = 72[/tex]
[tex]c = 24[/tex]

Suppose Jessica's route from her house to school consists of two straight legs: First, she drives straight for 5 miles, and then she makes a right turn of 45 degrees and drives another 9 miles. What is the distance (as the crow fl ies) from Jessica's school to her house in miles? (Round your answer to the nearest hundredth.
The distance from Jessica's school to her house is 7.48 miles.
Consider following diagram.
In right triangle ABC, vertex B is the Jessica's house vertex A be her school.
The route from her house to school consists of two straight legs.
She drives straight for 5 miles, and then she makes a right turn of 45 degrees and drives another 9 miles.
⇒ BC = 5 miles and AC = 9 miles
We need to find the distance from Jessica's school to her house in miles.
i.e., we need to find AB
Using Pythagoras theorem,
AC² = AB² + BC²
9² = AB² + 5²
AB = √(81 - 25)
AB = 7.48
Therefore, the distance from Jessica's school to her house is 7.48 miles.

The correct point slope form is y - 1 = 2 ( x - 9).
What is the point slope form?
The equation of a straight line that passes through a particular point and is inclined at a specific angle to the x-axis can be found using the point slope form. Every point on a line must satisfy the equation for the line in order for it to exist. This implies that a line is represented by a linear equation in two variables. Depending on the facts at hand, there are different ways to find a line's equation.

according to a recent student poll, \frac{5}{7} of the 21 members of the finance club are interested in a career in investment banking. if two students are chosen at random, what is the probability that at least one of them is interested in investment banking?
The probability that at least one of them is not interested in investment banking is 13/14.
What is a probability?It is a branch of mathematics. The possibility of the outcome of any random event is termed as probability. The range of the probability must be between o to 1. Here o indicates impossibility of an event and 1 indicates certainty. Probability can be expressed in proportions. Probability deals in finding the occurrence of an event.
Probability of the first person who is not interested in investment banking is 6/21
Probability of the second person who is not interested in investment banking and also first person was not interested then it is taken as 5/20.
probability that at least one is not interested in investment banking
=1- The probability that neither one of them is not interested in investment banking
=1-((6/21)×(5/20)

Considering the expression of a line, the slope of the line that passes through the pair of points (3, -4) and (-2,0) is -1.
Linear equationA linear equation o line can be expressed in the form y = mx + b
where
x and y are coordinates of a point.m is the slope.b is the ordinate to the origin and represents the coordinate of the point where the line crosses the y axis.Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope of the line can be calculated using:
m= (y₂ - y₁)÷ (x₂ - x₁)
Equation in this caseIn this case, being (x₁, y₁)= (3, -4) and (x₂, y₂)= (-1, 0), the slope m can be calculated as:
m= (0 - (-4))÷ (-1 -3)
m= (0 +4)÷ (-1 -3)

How to Find the Equation of a Line?For a line that passes through the origin (0, 0) of a graph, the equation that represents the line can be written in slope-intercept form as y = mx, where the slope of the line is represented as m.
The y-intercept of this type of line is zero, that is why we have the equation expressed as y = mx. Where the y-intercept is not equal to zero, the equation of the line would be expressed as y = mx + b, where b is the y-intercept and m is the slope of the line.
Find the slope of the line using two points on the line, (0, 0) and (3, 2):
Slope of the line (m) = (2 - 0)/(3 - 0)
Slope of the line (m) = 2/3.

On Bennett’s 5th birthday, his uncle invested $2,000 in a CD account that was locked into a 3.2% interest rate, compounded daily. How much will Bennett have in the account when he turns 18?
The amount Bennet will have when he turns 18 will be equal to $3020.
Compound interest is the type of interest charged by banks or institutions on individuals in which the amount after 1 year becomes the principle for the next year. It can be calculated daily, monthly or yearly etc. The formula for compound interest compounded daily will be
A = P(1 + r/n) ^nt, where A is the amount, P is the principle, which is equal to $2000, r is rate of interest which is 3.2% or 0.032, n is compounding frequency which is equal to 365 and t is the time which is equal to 13 years. Now, the amount will be
A = 2000(1 + 0.032/365) ^365×13
A = 2000(1.51)
A = $3020 which is the required amount.

For the equation |2-2x| = 14, find all values of x which makes the equation true
Answer:
x=-6,8
Step-by-step explanation:
First, let's observe our equation, there is an absolute value (|x|) that means 'x' will have two answers most likely positive and negative.
First we will take off the lines.
now we have
2-2x=14
next minus 2 out of both side of the equation
2 - 2 -2x = 14- 2
-2x =12
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = 12}{ - 2} [/tex]
we will cancel out - 2
[tex]\frac{x = - 6}{1} [/tex]
x= -6
We aren't done yet since this is an absolute value we have to convert the sum of the equation ( 14) to negatives now which will be in this case (-14)
your new equation will look like this
2-2x= -14
next minus 2 out of both side of the equation
2 - 2 -2x = -14- 2
-2x = - 16
now we will divide -2 from both side of the equation
[tex] \frac{ - 2x = - 16}{ - 2} [/tex]
we will cancel out - 2
[tex] \frac{x = 8}{1} [/tex]
x = 8
Check:x = -6
2 - 2x = 14
2 - 2(-6) = 14.
2 + 12 = 14✓.
x= 8
2 - 2x = -14
2 - 2 (8) = -14
2 - 16 = -14✓

The inequality expression given as |2x - 6 | < 0 has a solution of x > 3
How to solve the inequality?From the question, the inequality is given as
|2x-6|<0
This gives
|2x - 6 | < 0
Remove the absolute bracket
So, we have the following representation
2x - 6 > 0
Add 6 to all sides of the inequality
So, we have
2x - 6 + 6 > 0 + 6
Evaluate the like terms
So, we have
2x > 6
Divide through by 2
x > 3
Hence, the solution to the expression is x > 3

The statement that does not describe the data set 6, 8, 8, 10, 10, 10, 10, 12, 12, 14 is:
(C) The range of the data set is 15.
Consider the data set,
6, 8, 8, 10, 10, 10, 10, 12, 12, 14
The mean of the data set will be:
mean = ( 6 + 8 + 8 + 10 + 10 + 10 + 10 + 12 + 12 + 14 )/ 10
mean = 100/10
mean = 10
The data set in ascending order are:
6, 8, 8, 10, 10, 10, 10, 12, 12, 14
As the number of terms is even. Therefore, the median will be the sum of two middle numbers divided by 2.
So,
Median = ( 10 + 10 )/2 = 20/2 = 10
The mode of a data set is the maximum number of times a number appears in the data set.
Therefore, the mode of the data set is 10.
The range of the data set is the difference between the highest and the lowest number in the data set.
Range = 14 - 6 = 12
The data set is a symmetric distribution if the mean, median, and mode all fall at the same point.
As the mean, median, and mode are 10, 10, and 10 respectively. Hence, the data set is symmetric.
Hence, statements (A), (B), and (D) are true.

List the partial products of 242 and 28.
The partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.
What is meant by partial product?To estimate the partial product of two numbers, first, we write both numbers as the sum of the place values of the digits. Multiply each place value of the first number by the place value of the second number.
Given: 242 × 28
(200 + 42) × (20 + 8)
(200 × 20) + (200 × 8) + (42 × 20) + (42 × 8)
simplifying the above equation, we get
200 × 20 = 4,000
200 × 8 = 1,600
42 × 20 = 840
42 × 8 = 336
The above values are the partial product.
4,000 + 1,600 + 840 + 336 = 6,776
Therefore, the partial products of 242 × 28 are 4,000, 1,600, 840 and 336 and the value of 242 × 28 exists 6,776.
