Final answer:
This story problem involves calculating the sales and remaining stock of 40 apples and 17 pears at Ms. Adams' farmer's market stand, applying basic arithmetic operations in a real-life scenario.
Explanation:
Imagine a local farmer's market where Ms. Adams has a stand selling fruits. This particular Saturday, she starts with 40 apples and 17 pears. Throughout the day, customers buy apples and pears at different rates. By midday, half of the apples were sold. An hour later, five customers each bought 2 pears. By the end of the day, Ms. Adams noticed she sold twice as many apples as pears.
Your task is to use this story to calculate:
How many apples did Ms. Adams sell?How many pears did she sell?How many of each fruit does she have left?This problem helps students practice basic subtraction, division, and multiplication within a real-world context, applying arithmetic operations to solve a practical problem.
The parallelogram shown below has an area of 135 units2 Find the missing base.
===================================================
Explanation:
The area of the parallelogram is equal to the base times height. The formula to use is A = b*h. The height and base are always perpendicular to one another.
The base is some unknown variable b. Multiply the base by the height 15 to get 15*b which is equal to the area 135
Therefore, 15*b = 135
Divide both sides by 15 and we isolate b
15b = 135
15b/15 = 135/15
b = 9
So the base is 9
Check:
area = base*height = 9*15 = 135
so the answer is confirmed
side note: we never use the value 17 at all. It is likely put in there as a distraction.
Answer:
9

What is the value of this expression?
22.26 x 10^7 is the correct answer
Multiply the decimal numbers:
5.3 x 4.2 = 22.26
When multiplying scientific numbers, add the exponents together: 4+3 = 7
So you now have 22.26 x 10^7
Now you need to convert 22.26 to a scientific number, by only having one number to the left of the decimal point.
You need to move the decimal 1 place to the left, which means you need to add 1 more to the exponent.
The final answer would be 2.226 x 10^8

A certain gas station requires a minimum of $5 to use a debit card. You plan on buying a soda and however many bags of cheetos required to use your debit card. A soda costs $1.20 and bags of cheetos cost $1.40 each. Let x be the number of bags of cheetos you buy, and create an inequality that models the situation above
Answer:
1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5
Step-by-step explanation:
So since you are only buying 1 soda and you are buying multiple bags of Cheetos so you are able to use you debit card and meet the requirement of at least $5, you can make the inequality:
1.20 + 1.40x ≥ 5, or $1.20 + $1.40x ≥ $5
where x is the number of bags of Cheetos.

Answer:
15.8
Step-by-step explanation:
Rounding to the nearest tenths means we are focusing on the number 7 and the number after it- 5. Because it is a 5, we will round the number 7, one higher. If it were to be a 4, it would stay a 7.
Answer:
15.8 is the Answer
Step-by-step explanation:
1) 5 in the hundreds place will be turn to 6 due to the fact that in can round up because a 5 is in the thousandth place.
2) Since 6 is 5 and greater than 5 it will round up 7 in the tenths place to 8.

Point A (-7,-2) is rotated 270 counterclockwise and then shifted down 3 units. What are to coordinates of K’
Answer:
K'= (-2, 4)
Step-by-step explanation:
First we are going to rotate our point 270° counterclockwise.
The rule for a 270° counterclockwise rotation is [tex](x,y)-->(y,-x)[/tex], which means that we just need to interchange the coordinates of the point and change the sign of the x-coordinate:
[tex](x,y)-->(y,-x)[/tex]
[tex](-7,-2)-->(-2,-7)[/tex]
[tex](-7,-2)-->(-2,-(-7))[/tex]
[tex](-7,-2)-->(-2,7)[/tex]
Now, to shift the point 3 units down, we just need to subtract 3 units from the new y-coordinate of our resulting point form the previous procedure:
[tex](x,y)-->(x,y-3)[/tex]
[tex](-2,7)-->(-2,7-3)[/tex]
[tex](-2,7)-->(-2,4)[/tex]
We can conclude that the coordinates of K' are (-2, 4)

The answer is 2. The rate of change between -1 and 0 is 3 and between 0 and -1 is 1. The average between 3 and 1 is 2.
Answer:
- 2
Step-by-step explanation:
The average rate of change in the closed interval [ a, b ] is
[tex]\frac{f(b)-f(a)}{b-a}[/tex]
here [ a, b ] = [ - 1, 1 ]
f(b) = f(1) = 1 - 2 = - 1
f(a) = f(- 1) = 1 + 2 = 3
Hence
average rate of change = [tex]\frac{-1-3}{1-(-1)}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2

The answer would be Loan A
even though she'll pay more per month, with the others she'll pay be paying more by the time she as payed it off due to having to pay interest over a longer period of time
Answer:
Loan A is the cheapest.Step-by-step explanation:
The different loan plans are showed in the image attached.
Loan A: 12 months of duration with 9.50%.
Loan B: 24 months of duration with 8.75%.
Loan C: 36 months of duration with 7.75%.
Loan D: 48 months of duration with 6.60%.
Now, all loans are compouneded monthly. Let's the compound interest formula
[tex]A=P(1+\frac{r}{n} )^{nt}[/tex]
Loan A:
[tex]A=2500(1+\frac{0.095}{12} )^{12(1)}\\A=2,748.12[/tex]

the scuba diver standing on a boat is at an altitude of 1.3 meters above sea level. The scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute. what equation can be used to represent the divers altitude
Since the scuba diver jumps into the water and decreases his altitude by 5.6 meters in one minute, the equation that can be used to represent the divers altitude is [tex]y = -5x + 1.3[/tex]
What is the eqquation?The standard equation is [tex]y = mx + b[/tex]
y,x = variables
m = rate of change
b = initial value of y.
y = the height of the scuba driver after x minutes.
Given that b = 1.3
m = -5.6(decrease in altitude)
Then the equation can be written as ; [tex]y = -5x + 1.3[/tex]

The equation that represents the scuba diver's altitude after jumping into the water is y = 1.3 - 5.6t, where y is in meters and t is in minutes.
Let y represent the diver's altitude in meters relative to sea level after t minutes. Initially, at sea level, we have y(0) = 1.3. Due to the descent in water, the altitude decreases by 5.6 meters per minute, which means the altitude change per minute can be represented by
-5.6t. Thus, the equation that can be used to represent the diver's altitude as a function of time is:
y = 1.3 - 5.6t
where y is in meters and t is in minutes.

The statement that is most likely to be true for this distribution is The mean is greater than the median.
What is right skewed distribution?This distribution is "bunched up" at the left and has a larger tail to the right, indicating that it is right skewed. The median will be nearer the left side of the graph in a right-skewed distribution since most of the data points are at the smaller end.
The mean will rise and become greater than the median due to the increased numbers in the "tail". A positively skewed distribution, also known as a right-skewed distribution in statistics, is one in which the majority of values are concentrated at the left tail of the distribution while the right tail is longer. The distribution that is negatively skewed is directly opposed by the positively skewed distribution.

EXPLANATION.
The given function is
[tex]f(x) = 2 {x}^{3} + 21[/tex]
Let
[tex]y= 2 {x}^{3} + 21[/tex]
Solve for x.
[tex]2 {x}^{3} = y - 21[/tex]
[tex] {x}^{3} = \frac{1}{2} y - \frac{21}{2} [/tex]
Take cubic root of both sides,
[tex]x = \sqrt[3]{ \frac{1}{2} y - \frac{21}{2} } [/tex]
x is defined for all real values of y.
The range refers to the values of y, for which x is defined.
Hence the range is all real numbers.

Step-by-step explanation:
11. g(x) =5x³
g₁ = 5x₁³
g₂ = 5x₂³
g₂/g₁ = (x₂/x₁)³
a. x is doubled. g₂/g₁ = (2x₁/x₁)³ = 2³ = 8
If x is doubled, g is multiplied by eight.
b. If x is tripled, g₂/g₁ = (3x₁/x₁)³ = 3³ = 27
If x is tripled, g is multiplied by 27.
c. If x is halved, g₂/g₁ = (½x₁/x₁)³ = (½)³ = ⅛
If x is halved, g is divided by 8.
12. ƒ(x) = 3/x⁴
f₁ = 1/x₁⁴
f₂ = 1/x₂⁴
f₂/f₁ = (x₁/x₂)⁴
a. x is doubled. f₂/f₁ = (x₁/2x₁)⁴ = (½)⁴ = 1/16
If x is doubled, f is divided by 16.
b. If x is quadrupled, f₂/f₁ = (x₁/4x₁)⁴= (¼)⁴ = 1/256
If x is tripled, f is divided by 256.
c. If x is halved, f₂/f₁ = [x₁/(½x₁)]⁴ = 2⁴ = 16
If x is halved, f is multiplied by 16.
13. V = ⁴/₃πr³
V₁ = ⁴/₃πr₁³
V₂ = ⁴/₃πr₂³
V₂/V₁ = (r₂/r₁)³
r is doubled. V₂/V₁ = (2r₁/r₁)³ = 2³ = 8
The volume of the sphere is multiplied by 8.
14. V = πr²h
V₁ = πr₁²h
V₂ = πr₂²h
If r is doubled and h stays the same, V₂/V₁ = (2r₁/r₁)² = 2² = 4
The volume of the cylinder is quadrupled.

What is a theoretical and Experimental Probability?
Answer:
See below...
Step-by-step explanation:
Theoretical probability is the probability that something should happen based on the beginning conditions. Such as having a jar of 30 marbles with 5 being blue. The probability of pulling out a blue marble when selecting 1 marble is
5/30, or 1/6. Theoretically you should pull one blue marble out every 6 times you pull a marble out.
This isn't guaranteed to happen though, that's where experimental probability comes form.
Experimental probability is the number of desired outcomes achieved, divided by the total number of outcomes. This is based on what actually happened. Say you selected a marble, and put it back 10 times, recording the color each time and you got 2 blue marbles. Your experimental probability is
2/10, or 1/5, which doesn't match the theoretical probability. The more times this experiment is conducted, the closer your result will be to the theoretical probability
