If the cost to fill the pool is $2.55 per cubic foot, how much will it cost to fill the pool?
It will cost $_____ to fill the pool.

Answer:

45 square ft^2

Step-by-step explanation: The formula of the area of the trapezoid is A=(a+b)/2 x h. A represents the top while b represents the bottom. 15+3=18 and 18/2=9. If multiply the result by 5, you get 45 as the answer.

Answer:

y≈1.778 (or y=log(3600)/2 or y=log(6)+1)

Step-by-step explanation:

10^2y=3600

log(10^2y)=log(3600)

2y=log(36)+log(100)

2y=log(6²)+2

2y=2log(6)+2

2y-2=2log(6)

y-1=log(6)

y=log(6)+1

y≈1.778

the difference is $54

Step-by-step explanation:

I dont know if this helps but that what I came up with

= [tex] log_{ 3}({x}^{2} - 4) - log_{3}(x - 2) + log_{3}(x) [/tex]

= [tex] log_{ 3}(\dfrac{{x}^{2} - 4}{x - 2}) + 2 × 1[/tex]

= [tex] log_{ 3}(\dfrac{(x-2)(x+2)}{x - 2}) + 2 × 1[/tex]

= [tex] log_{ 3}(x+2) + 2 × 1[/tex]

Answer:

y = 9/4x -1/2

Step-by-step explanation:

4x + 9y -2=0

solve for y: 4x-2=-9y

(4x-2)/-9 =  

y =4/-9x-2/9

perpendicular means reciprocal of slope. So 4/-9 changesz to 9/4

For the point plug in y and x:

9/4*2+b=4

Answer:

60ml of the 50% alcohol solution  and 20ml of the 6% alcohol solution

Step-by-step explanation:

We can build a system of equation for solve this problem

x = first solution

y = second solution

x + y = 80

0.5x + 0.06y = 80 * 0.39

x + y = 80

0.5x + 0.06y = 31.2

x = 80 -y

0.5(80-y) + 0.06y = 31.2

40 - 0.5y + 0.06y = 31.2

-0.44y = -8.8

y = 20

x = 80 - 20 = 60

Let the speed of one rider = x

The speed of the second rider would e 2x ( twice as fast)

The total speed of the two riders would be x + 2x = 3x

Speed = Distance / time

Using the numbers:

3x = 72/3

Simplify:

3x = 24

Divide both sides by 3:

x = 8

The speed of one rider is 8 miles per hour

The speed of the second rider is 2(8) = 16 miles per hour.

Answer:

Part A: 3197

Part B: 62

Step-by-step explanation:

Part A: To make this easier just multiply 96 books by 34 rows which is 3264 books, but then since you are taking away 2 books for every row, multiply 2 by the 34 rows which is 68 but since the first row starts at 96 we will take away 1 row from the 68 which is 67. Then subtract 67 from the 3264 books and get 3197 books.

Part B: To make this easier just multiply 17 by 2 since we know for every row, 2 books are taken away and that equals 34 so subtract 34 from 96 and get 62.

Answer:

a(17) = 64

Step-by-step explanation:

you can create an arithmetic sequence formula as follows:

a(n) = a(1) + d(n-1)   where a(1) is the first value and d is the common difference

a(17) = 96 -2(17-1)

a(17) = 96 - 32

a(17) = 64

Answer:

x = 19

Step-by-step explanation:

Let's start solving:

5² - 3(3-1) = x

Multiply 5 and 5 and also multiply 3(3-1)

25 - (9-3) = x

Subtract 6 from 25

25 - 6 = x

Simplify

x = 19

Answer:

  x = 2 2/3 is the solution; x = 2 is not a solution.

Step-by-step explanation:

The solution is ...

  3x +4 = 12 . . . . . . given

  3x = 8 . . . . . . . . . .subtract 4

  x = 8/3 = 2 2/3 . . . divide by 3

x = 2 is not a solution. The correct solution is x = 2 2/3.

Answer:

the number of days when instructor do the work alone is 8 days

Step-by-step explanation:

Given that

The apprentice can do the work in 24 days

And, the apprentice and  instructor together can do it in 6 days

We need to find out the number of days when instructor do the work alone

So,

[tex]= \frac{1}{6} - \frac{1}{24} \\\\= \frac{4 - 1}{24} \\\\= \frac{3}{24} \\\\= \frac{1}{8} \\\\= 8[/tex]

hence, the number of days when instructor do the work alone is 8 days

Step-by-step explanation:

Option (D) During the first half of 2015, the weight of Ava's puppy increased two times as fast is the correct answer.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner. A graph is a diagram that represents the variation of a variable in comparison with that of one or more other variables.

For the given situation,

Sam and Ava compared the weights of their puppies each month during the first half of 2015.

The graph shows the comparison between Sam's and Ava's puppies.

From the graph,

At the beginning of the month both the puppies have same weight. After a month, Ava's puppies weight increased rapidly than Sam's puppy.

Hence we can conclude that option (D) During the first half of 2015, the weight of Ava's puppy increased two times as fast is the correct answer.

Answer:

All of them.

Step-by-step explanation:

Rational numbers are defined as the numbers that can be expressed as the ratio of two integers(a/b) where b must be a non-zero number. The rational numbers display a terminating characteristic and they also contain repeating, as well as, recurring digits. All the given numbers are rational as they can be written in the form of p/q.

23.429 = It can be written as a fraction. So, it is a rational number.

10 = 10 is a whole number and it can be written in the form of a/b i.e. 10/1. So, it is a rational number.

13 = 13 also can be written in ration form as 13/1. Therefore, it is also a rational number.

151 = It can be written as 151/1. Hence, it is a rational number.

8/7 = It is already mentioned in the form of a/b. So, it is a rational number.

-4.93 = since it is an integer, it will surely be a rational number.

If cos < 0 and cot > 0, then the terminal point is determined by

C. quadrant 3.

In quadrant I the referece angle Ф is Ф.

In quadrant II the referece angle Ф is (π - Ф).

In quadrant III the referece angle Ф is (π + Ф).

In quadrant IV the referece angle Ф is (2π - Ф).

We know, cos is -ve on III and IV quadrants, and cot = 1/tan is +ve on I and III quadrant.

Therefore, The combined condition cos < 0 and cot > 0 satisfies on the II quadrant.

Answer:

2826  inches^2

Step-by-step explanation:

The general formula for the total surface area of a regular pyramid is

T.S.A.=12pl+B

Where p represents the perimeter of the base, l the slant height and B the area of the base.

The perimeter of the base is.  

p=2L+2W

P=2*10+2*9

P=20+18

P= 38  inches

The area of the base is.

B=10*9

B=90in^2

T.S.A.=12(38)(6)+90              

T.S.A=2736+90

T.S.A=2826  inches^2
