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.

That is, grouping fractions.

Answer:

Profit = $(700 - 42x - 56y)

Step-by-step explanation:

For large candles, the selling price is $10 and its making cost is $x.

So, by selling a large candle the profit is $(10 - x)

Again for small candles, the selling price is $5 and its making cost is $y.

So, by selling a small candle the profit is $(5 - y)

Therefore, in a sell of 42 large candles and 56 small candles the total profit will be, P = 42 (10 - x) + 56 (5 - y)

⇒ P = 420 - 42x + 280 - 56y {Applying distributive property}

⇒ P = $(700 - 42x - 56y) (Answer)

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

To find the area of shaded 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.

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.

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.

Answer:

B. Between 40 and 140 Fahrenheit

Step-by-step explanation:

This is called the "Danger Zone" because between these temperatures bacteria grow the fastest. Doubling time can be as little as 20 minutes.

Answer:

$250

Step-by-step explanation:

you add cost of meat and other ingredients

1+1.5=2.5

x100 cause there are 100 burritos

2.5x100

$250

Answer:

$250

Step-by-step explanation:

you include cost of meat and different fixings

1+1.5=2.5

x100 = 2.5x100 = $250

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

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.
