Given:

Total shelves: 6

Books per shelve: 72

Total books = ?

Solution:

Total books: 6 * 72 = 432

                                                           Total books = 432

Given:

Fiction books = 1/3 of total books

Solution:

Nonfiction books = Total books - 1/3 of total books

                              =   432 - 1/3 * 432

                               = 432 - 166 = 266

                                           Non- fiction books = 266

To find the area of a rectangular shape, we need to have the length and width of the shape.

Here the room is rectangular in shape.

The length of the room is 60 meters and lets say the width of the room is 'w' meters.

The area of room is given which is 2,400 square meters.

The area of rectangle is given by:

[tex]length \times width[/tex]

Now, plugging the values of the length and width, we get:

[tex]Area = 60 \times width[/tex]

[tex]2400= 60 \times width[/tex]

Solving for width, we get:

[tex]Width= \frac{2400}{60} =40[/tex] meters.

So, the width of the rectangular room is 40 meters.

Answer:

36x44 feet are the dimensions of the yard.

Step-by-step explanation:

Given that the blueprint for landscaping a yard has a scale of 1/2" to 1 foot.

i.e. scaling factor is 1/2 for one foot.

If real dimension is 1 foot, it is shown as 1/2 inch in blue print.

Using this we can find the real dimensions if given blue print dimensions.

The blueprint is a rectangle 18inches by 22 inches,

Hence real length of rectangle = 18(2) feet = 36 feet

Width of rectangle = 22(2) = 44 feet

i.e. the yard has dimensions as 36x44 feet.

Answer: 60 Guppies.

Step-by-step explanation: If Ben has 3 times as much guppies as goldfish then it is 3 x 20 which = 60.

Assuming a regularly shaped rectangle, the formula for the area is given as:

A = L * W

where L and W are the length and width respectively

A = 3.6 x 10^2 miles * 2.8 x 10^2 miles

A = 100,800 square miles

or

A = 10.08 x 10^2 miles

Answer: D. There is a strong negative association between the variables.

Step-by-step explanation:

We know that when the value of the correlation coefficient lies between -1 to -.05 , then we say there is strong negative correlation between the variables.

OR

When the value of the correlation coefficient lies between 0.5 to 1, then we say there is strong positive correlation between the variables.

Given : In one study, it was found that the correlation coefficient between two variables is -0.93.

∵ -1< -0.93 <-0.5

Then , it  indicates that there is a strong negative association between the variables.

Answer:

The correct option will be:   c.  8 pieces of wood.

Step-by-step explanation:

Suppose, the number of pieces of wood along each side of the chess board is  [tex]x[/tex]

The area of each piece of wood is given as 1 square inch. So, the length of each piece of wood will be: [tex]\sqrt{1}= 1[/tex] inch.

And the total length of  [tex]x[/tex]  number of pieces of wood will be:  [tex]1x[/tex] inches.

Given that, the area of the chess board is 64 square inches. So, the length of each side will be:  [tex]\sqrt{64}=8[/tex] inches.

Thus, the equation will be.........

[tex]1x=8\\ \\ x=\frac{8}{1}=8[/tex]

So, he should put 8 pieces of wood along each side.

Answer: it will be 8

Step-by-step explanation: because 8×8=64

10 cubes for the base

Answer:

Option (D) 10 cubes

Step-by-step explanation:

The given structure is formed by assembling the cubes.

Number of cubes required for upper layer of the structure = 7 cubes

Now we have to find how many cubes will be required to form the lower layer of the structure.

From the structure ⇒

Cubes in lower layer = cubes in upper layer + 3 more cubes

                                  = 7 + 3 = 10 cubes

Therefore, 10 cubes will be required to form the base of the structure.

Option (D) 10 cubes is the answer.

x = ± 3√6

2x² - 6 = x² + 48 ( subtract x² from both sides )

x² - 6 = 48 ( add 6 to both sides )

x² = 54 ( take the square root of both sides )

x = ± √54 = ± 3√6

The answer would be B because since -8 is negative, you would flip its sign

For this one, look at the symbols inside each angle.  In math, the rounded edges inside of angles mean they are congruent.  So find which ones have the same amount of rounded edges and that would be your answer.

NKW ≅ UZE

put the corresponding angles in the middle.  Since the object you were comparing to had the one line as the middle point, then that is your middle as well.

Hope this helps! Comment with any questions you may have.

Answer:

[tex]\Delta UZE\cong \Delta NKW[/tex]

Step-by-step explanation:

We have been given a graph of two triangles and we are asked to find the correct congruence statement for our given triangles.

We can see in triangle NKW and triangle UZE.

[tex]EZ\cong WK[/tex],

[tex]\angle ZEU\cong \angle KWN[/tex],

[tex]\angle UZE\cong \angle NKW[/tex].

Since two angles and included side of triangle NKW is congruent to two angles and their included side of triangle UZE, therefore, [tex]\Delta UZE\cong \Delta NKW[/tex] by Angle-Side-Angle congruence theorem.

Step-by-step explanation:

y [25, 100] is the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10.

Therefore, the correct answer is:

C. y [25, 100]

Here,

To find the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10,

we need to determine the minimum and maximum values of the population during this period based on the graph.

From the graph, we can see that the population values are between approximately 25 and 100 (inclusive) during months 5 to 10.

The square brackets [ ] denote that the endpoints are included in the range.

so, we get,

y [25, 100] is the range of the population of Blue Whales off the coast of Antarctica from months 5 to 10.

Therefore, the correct answer is:

C. y [25, 100]

Answer: 3756

Step-by-step explanation:

33 x 100 = 3300

44 x 10   =    440

16 x 1      =      16

Total:         3756

The number represented by 33 hundreds plus 44 tens plus 16 ones is 3756, which is found by adding 3300 (33 times 100), 440 (44 times 10), and 16 (16 times 1) together.

The question involves adding numbers that compose a whole number through place values. In this case, we are looking at hundreds, tens, and ones. To solve this, we add up each group's contribution to the total. We have:

Adding these together:

3300 + 440 + 16 = 3756

So, 33 hundreds plus 44 tens plus 16 ones represents the number 3756.

40 dollars per 5 students=9 dollars per 1 student

divide both sides by 5.

The area of the field is obtained by multiplying length by width resulting 75,000 square meters. Converting this to square kilometers by dividing by 1,000,000 gives the area in square kilometers as 0.075 km².

To calculate the area of the rectangular field, we multiply the length by the width. Given that the length is 300 meters and the width is 250 meters, the area in square meters would be 300 meters * 250 meters = 75,000 square meters.

Keep in mind that 1 square kilometer (km²) is equivalent to 1,000,000 square meters (m²). So, to convert the area from square meters to square kilometers, we divide the area in square meters by 1,000,000. Therefore, the area of the field in square kilometers is 75,000 m² / 1,000,000 = 0.075 km².

Answer:

72-16

Step-by-step explanation:

Difference is represented by the subtraction of 2 numbers. If we want to represent the difference of 2 numbers, we need to subtract one number from the other number.

4. The translation is considered an isometry or rigid motion. The figure's size, shape, area, etc has not changed. The only thing that changed is its position.

5. The rule stated means you shift the point 3 units to the right and 4 units up.

6. The rule would be (x,y) ---> (x-1, y-3) so we effectively subtract 1 from the x coordinate; subtract 3 from the y coordinate

7. Add 2 to the x coordinate to get x+2 = 2+2 = 4. Subtract 1 from they coordinate and we have 5-1 = 4. The point ends up at (4,4). Check out the attached image below.

Remark

If 7/10 do have full or part time jobs then 3/10 do not.

That comes from 1 which represents all the students subtract 7/10 to get 3/10

Solution

Those without jobs = 4900 * 3/10 = 4900 *0.3 =  1470 that do not have any kind of job.
