Answer:

D. (2 + 3/7) + 4/7

Step-by-step explanation:

In B and C, the numbers involved in expressions are integers.

Hence, they can be easily added or subtracted.

In D, the numbers involved in expression are fractions which are not grouped together.

They can be added but by using associative property, it becomes much more easier.

The area of shaded rectangle is 8/3 square units.

To find the area of shaded rectangle.

What is rectangle?

A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees.

Given that:

length=4 units

width= 1-unit

The rectangle is subdivided into 3 parts parallely.so 1 units is unshaded and rest are shaded.

Area of rectangle =length*width

Area of bigger rectangle =length*width

                                       =4*1 square units

                                       =4 square units

width is subdivided into 3 parts .

so, 1/3,1/3,1/3 are the width.

Area of un shaded rectangle=length*width

                                                 =4*1/3 square units

                                                  =4/3 square units

so, Area of bigger rectangle=Area of un-shaded rectangle+ Area of shaded rectangle

4 =4/3+Area of shaded rectangle

Area of shaded rectangle=4-4/3

Area of shaded rectangle=12-4/3

Area of shaded rectangle=8/3 square units

Therefore, the area of shaded rectangle=8/3 square units.

Mr Davis has displayed data using box and whisker plots representing the scores on the first exam in his two calculus classes. Using these plots, what can Mr Davis correctly deduce about how the two classes compare?

Answers

Answer: The first and third choices are deductions that Mr. Davis can make from the data displayed.

Step-by-step explanation:  The last choice is partly true. The highjest individual score was a student in third period, but most schools consider failing to be somewhere below 60 to 67%. There are several of scores below those numbers. The dots at the left end are "outliers."  

The second choice may be true, but the data is about the scores on the test, not the number of students in the classes.

1. The relationship between a distance in yards (y) and the same distance in miles (m) is
described by the equation y = 1760m.
a. Find measurements in yards and miles for distances by filling in the table.
distance measured in miles
distance measured in yards
1
5
3,520
17,600
b. Is there a proportional relationship between a measurement in yards and a
measurement in miles for the same distance? Explain why or why not.

Answers

Therefore, the ratio of yards to miles is always constant, making it a proportional relationship.

What is equation?

An equation is a mathematical statement that shows the equality between two expressions. It typically includes one or more variables, which are unknowns that can take on different values. An equation can be solved by finding the value or values of the variable(s) that make both sides of the equation equal.

Here,

a. Using the equation y = 1760m, we can fill in the table as follows:

distance measured in miles distance measured in yards

1                        1,760

5                8,800

3.520     6,195.2

17,600      30,800,000

b. Yes, there is a proportional relationship between a measurement in yards and a measurement in miles for the same distance. The equation y = 1760m shows that the number of yards is always 1760 times greater than the number of miles. This means that if you double the number of miles, the number of yards will also double, and if you triple the number of miles, the number of yards will triple, and so on.

The Farmers Market sells apples by the bushel, and each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples? It’s says show work

Answers

Answer:  4 apples in 1 lb

Step-by-step explanation:  There are twice as many small apples  as large apples, so multiply 2 × 84 = 168

to find apples per pound, divide the total number of apples, 168,  by the weight of the bushel: 42 lbs.

168 /42 = 4 apples/lb

The required number of small apples in one pound is 4.

Given that,
Each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb. of small apples, is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Large apples in 1 pound = 84 / 42 = 2
Now, according to the question,
Number of small apples = 2 (number of large apples)
Number of small apples = 2 (2)
Number of small apples = 4

Thus, the required number of small apples in one pound is 4.
