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.

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.

Explanation:

Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the "Danger Zone." Never leave food out of refrigeration over 2 hours.

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:

1)13/3 2)-1/2 3)5/6

Step-by-step explanation:

1) Determine the sign(since there is 2 negatives it turns positive)

Then you simplify the complex fraction to 4/3+3

Then you calculate

2) Determine the signs you get to -6+4/-1+5

calculate -2/4

then solve

3) multiply everything to get 8-(5+(-12))/16+2

Then you calculate 8-(5-12)/18

Calculate again8-(-7)/18

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:

4/5 divided by 1/5

Step-by-step explanation:

Answer:

[tex]z = 6.5[/tex]

Step-by-step explanation:

If we take a look at the problem, we are solving for z.

[tex]\frac{118}{13} = \frac{59}{z}[/tex]

To figure it out, we have to cross multiply. So we take [tex]118 * z[/tex] and [tex]59 * 13[/tex], which gives us [tex]118z =767\\[/tex]. Next, we divide both sides with 118.

[tex]\frac{118}{118}z=\frac{767}{118}\\ \\z = 6.5[/tex]

Then, we get 6.5 as our answer!

Answer: It is a 90 Clockwise Degree Turn.

Step-by-step explanation:

From my knowledge, a 90-degree turn is a turn to the right.

So if you turn the "C" in the Y-axis 90 degrees you will get The "C" on the X-axis.

For Example: When you walk around a street you either turn 90 degree's to the right or 90-degrees to the left.
