Answer: The answer for 9 is 50 miles per hour and the one who drove farthest is is ben because at 5 hours he drove already 250 miles. And for number 9 according to the table she is driving 15 miles per hour because on the bottom it always adds up by 15 miles.
Step-by-step explanation: So first to figure out 9 I used y2-y1/x2-x1 to figure out the rate of change and got 50 miles per hour and the point I used were (5,100) and (5,250). Then According to Ben's graph it shows that he drove 250 miles at 5 hours while sally was at 100 miles for 5 hours. So Ben drove the farthest. Then finally for number 9 I concluded that sally is driving 15 miles per hour because distance always adds up by 15 miles.
Hope this Helps :D

An apple orchard has honey crisp trees and mnintosh trees. The orchard has 1603 honey crisp trees. It has 327 more McIntosh trees than honeycrisp trees. About how many apple trees does the orchard have?
Answers
The number of apple trees the orchard have is 3533.
How to find the the number of apple trees in the orchard?The apple orchard has honey crisp trees and McIntosh trees.
The orchard has 1603 honey crisp trees.
It has 327 more McIntosh trees than honey crisp trees.
Therefore,
number of honey crisp trees = 1603
number of McIntosh trees = 327 + 1603
number of McIntosh trees = 1930
Therefore, the number of apples trees the orchard have can be calculated as follows:
number of apples trees = number of McIntosh trees + number of honey crisp trees
number of honey crisp trees = 1603
number of McIntosh trees = 1930
number of apples trees = 1930 + 1603
number of apples trees = 3533

There are four basic properties of numbers: commutative, associative, distributive, and identity. You should be familiar with each of these.
distributive property ;
According to this property, multiplying the sum of two or more addends by a number will give the same result as multiplying each addend individually by the number and then adding the products together.
The commutative property states that the change in the order of two numbers in an addition or multiplication operation does not change the sum or the product.

Jane decides that he is spending too much money at his favorite coffee place. He finds that he can buy a bag of 24 ounces of ground coffee for $12 to make at home. It takes 2 tablespoons of ground coffee to make one cup of coffee. How much will each cup of coffee cost you? Note 2 tablespoons equals 1 ounce. Use the dimensional analysis method (use units in your calculations)
Answers
The amount that each cup of coffee cost you will be $0.5 per cup.
How to illustrate the information?It should be noted that the information illustrated that Jane decides that he is spending too much money at his favorite coffee place and she finds that he can buy a bag of 24 ounces of ground coffee for $12 to make at home.
It should be noted that since 2 tablespoons equals 1 ounce, the number of teaspoons will be:
= 24 × 2
= 48 teaspoons
Therefore, the amount that each cup of coffee cost you will be:
= Cost / Number of cups
= $12 / (48 / 2)
= $12 / 24.
= $0.5
Therefore, the amount that each cup of coffee cost you will be $0.5 per cup.

If you estimate the median and the mean, which statement is the appropriate statement for
the mean and the median?
a. Median=2 and mean = 5
b. Median=3 and mean = 3.5
c. Median = 3.5 and mean = 3
IMAGE ABOVE
Answers
The correct statements regarding the mean and the median of the distribution are given as follows:
b. Median = 3 and Mean = 3.5.
What are the mean and the median of a distribution?The mean of a data-set is given by the sum of all values in the data-set, divided by the cardinality of the data-set, which is the number of values in the data-set.The median of a data-set is given by the middle value of the data-set, which is the value for which 50% of the data-set is less than and 50% of the data-set is greater than.From the frequency table, we have that:
5 observations have a value of 1.7 observations have a value of 2.8 observations have a value of 3.6 observations have a value of 4.5 observations have a value of 5.3 observations have a value of 6.1 observations have a value of 7.1 observations have a value of 10.The number of values in the data-set is:
5 + 7 + 8 + 6 + 5 + 3 + 1 + 1 = 36.
Hence the mean is given by:
M = (5 x 1 + 7 x 2 + 8 x 3 + 6 x 4 + 5 x 5 + 3 x 6 + 1 x 7 + 1 x 10)/36 = 3.5.
The median will be the 36/2 = 18th value, which is of 3.
Hence the correct statement is:
b. Median = 3 and Mean = 3.5.

The elementary playground is a 1:6 scale representation of the high school activity field.
If the activity field is 21,600 square feet, what is the area of the playground?
Answers
Based on the scale factor of 1:6, if the area of the activity field is 21,600 square feet, the area of the playground is equal to 3,600 square feet.
Given the following data:
Scale factor = 1:6
Area of the activity field = 21,600 square feet.
What is scale factor?A scale factor can be defined as the ratio of two (2) corresponding length of sides, area, or diameter in two similar geometric figures such as equilateral triangles, river, planets in our solar system, etc.
Let E represent the area of the elementary playground.
Let H represent the area of the high school activity field.
Therefore, a mathematical expression which relates the area of the elementary playground to the area of the high school activity field is given by:
E : H 1:6 = x : 21,600
Evaluating, we have:
1/6 = x/21,600
Cross-multiplying, we have:
6x = 21,600
x = 21,600/6
x = 3,600 square feet.

A blimp can be seen flying at an altitude of 7200 feet above a motor speedway during a race. The slanted distance directly to the pagoda at the start-finish line is d feet. Express the horizontal distance h as a function of d.
Answers
The horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).
It is given in the question that:
Height at which blimp is flying (AB)= 7200 feet
The slanted distance to the pagoda (BC) = d feet
The horizontal distance (AC) = h
Let the angle made between slanted distance and horizontal distance be θ.
So, cosθ = AC/BC
cosθ = h/d
and also, sinθ = AB/BC
sinθ = 7200/d
Now, we know from the first trigonometric identity that cos²θ = 1 - sin²θ.
=> (h/d)² = 1 - (7200/d)²
=> (h/d)² = (d² - 7200)/d²
=> h² = d² - 7200
=> h = √(d² - 7200)
=> h = √(d + 7200) (d - 7200)
Thus, the horizontal distance as a function of d can be given as h = √(d + 7200) (d - 7200).

Answer:
Here both a & b are positive integers that are obtained from the expression (-a)(-b).
Step-by-step explanation:
It is given that a and b are both positive integers, therefore -a and- b are negative integers.
Now, using this we need to simplify the expression (-a)(-b);
Firstly, let us understand what are integers and types of integers;
The collection of whole numbers and negative numbers is known as an integer in mathematics.
Zero, a positive natural number, or a negative integer denoted by a minus sign are all examples of integers.
The inverse additives of the equivalent positive numbers are the negative numbers.
Now, let us understand what are positive and negative integers;
In fact, positive integers are a subset of the wider class of numbers known as integers.
Integers with a negative value are those that are less than zero. They exclude decimals and fractions.
Furthermore, the expression given is (-a)(-b) which is the product of two negative integers.
=> (-a)(-b)
=> ab
Therefore, here both a & b are positive integers that are obtained from the expression (-a)(-b).
