A rectangular swimming pool is 6 ft deep. One side of the pool is 2.5 times longer than the other. The amount of water needed to fill the swimming pool is 2940 cubic feet. Find the dimensions of the pool.

The smaller dimension of the pool is __ ft.
The larger dimension of the pool is __ ft.

Answers

Answer:

The smaller dimension of the pool is 14 ft.

The larger dimension of the pool is 35 ft.

Step-by-step explanation:

We are told that:

The rectangular swimming pool is 6 ft deep. Thus, depth: h = 6 ft

One side of the pool is 2.5 times longer than the other.

Thus, length = 2.5(width)

l = 2.5w and width = w

Volume; V = lwh = (2.5w × w × 6) = 15w²

The amount of water needed to fill the swimming pool is 2940 cubic feet.

Thus;

15w² = 2940

w² = 2940/15

w² = 196

w = √196

w = 14 ft

Length: L = 2.5w = 2.5 × 14 = 35 ft

Answer:

PN = 10

Step-by-step explanation:

Base angles converse theorem states that a triangle with two congruent angles is isosceles. The sides opposite to the two congruent angles are the congruent sides. The side between the two congruent angles is the base.

In this problem, it is given that <P = <O, hence ΔNOP is isosceles, because of base angles theorem. OP is the base, and hence NO is one of the congruent sides and therefore has to be congruent to PN. Which means that PN is 10.

Option B. f¯¹(x) = ³√(– x – 9)

Step-by-step explanation:

From the question given above:

f(x) = – x³ – 9

f¯¹(x) =?

We can obtain the inverse f¯¹(x) of the above equation by doing the following:

f(x) = – x³ – 9

Replace f(x) with y

y = – x³ – 9

Interchange x and y

x = – y³ – 9

Make y the subject . This is illustrated below:

x = – y³ – 9

Rearrange

x + 9 = – y³

Multiply through by –1

–(x + 9) = y³

y³ = – x – 9

Take the cube root of both side

y = ³√(– x – 9)

Replace y with f¯¹(x)

f¯¹(x) = ³√(– x – 9)

Thus, the inverse of the function

f(x) = – x³ – 9

is

f¯¹(x) = ³√(– x – 9)

According to an accepted chemistry reference, the
heat of vaporization of water is 540 calories per
gram. A student determined in the laboratory that
the heat of vaporization of water was 620 calories
per gram. The student's results had a percent error
of

Answers

Answer:

14.8%

Step-by-step explanation:

Step 1: Given data

True value for the  heat of vaporization of water (ΔH°vap(T)): 540 cal/g

Experimental value for the  heat of vaporization of water (ΔH°vap(E)): 620 cal/g

Step 2: Calculate the experimental percent error

To determine the experimental percent error we will use the following expression.

%E = |ΔH°vap(T) - ΔH°vap(E)|/ΔH°vap(T) × 100%

%E = |540 cal/g - 620 cal/g|/540 cal/g × 100%

%E = 14.8%

the length of a rectangular sing is 5 time its width. if the sign perimeter is 24 inches. what is the sign area ?

Answers

Answer:

20 in²

Step-by-step explanation:

Assuming that the width of the sign is x, then from the question, we're told that the length is 5 times it's width, so

b = x inches

l = 5x inches

Again, we're told that the perimeter of the sign is 24 inches, and we know already that the perimeter of a rectangle is given as

Perimeter = 2(l + b), substituting this, we have

24 = 2(5x + x)

24 = 10x + 2x

24 = 12x

x = 24 / 12

x = 2 inches.

Since x is the width of the rectangle, and it's 2 inches, we use it to find the length of the sign.

l = 5 * 2

l = 10 inches.

Then, we are asked to find the area of the sign. Area of a rectangle is given as

A = l * b, so if we substitute, we have

Area = 10 * 2

Area = 20 square inches

Use C for number of chocolate boxes and for number of ornament boxes.

Answers

she can buy 6 boxes of chocolates
and 8 boxes of ornaments
6*10=60 & 8*12=96
so you would add them and get
60+96=156

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The number of chocolate boxes is 6.

The number of ornament boxes is 8.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 5 is an equation.

We have,

Number of chocolate boxes = C

Number of ornaments boxes = B

The total cost of 14 boxes = $156

Cost of one box of chocolate = $10

Cost of one box of ornaments = $!2

Now,

C + B = 14  ______(1)

10C + 12B = 156  _______(2)

From (1) we get,

C = 14 - B ______(3)

Putting (3) in (2) we get,

10 (14 - B) + 12B = 156

140 - 10B + 12B = 156

140 + 2B = 156

2B = 156 - 140

2B = 16

B = 16/2

B = 8

Now,

C = 14 - B

C = 14 - 8

C = 6

Thus,

The number of chocolate boxes is 6.

The number of ornament boxes is 8.

Lateral Area = No lateral area (choice D)Surface Area = 25.97 square inches (choice E)Volume = 12.44 cubic inches (choice A)

============================================

Explanation:

Lateral area only applies to prisms and cylinders. Spheres do not have lateral sides, so there is no lateral area.

-----------------------

The radius is 1 & 7/16

Let's convert this to decimal form

1 & 7/16 = 1 + (7/16)

1 & 7/16 = 1 + 0.4375

1 & 7/16 = 1.4375

The radius is r = 1.4375 inches.

-----------------------

SA = Surface area the sphere

SA = 4*pi*r^2

SA = 4*pi*(1.4375)^2

SA = 25.9672267773281

SA = 25.97 square inches (choice E)

How will you graph the function g(x) = (x – 4)+ 12 using the parent quadratic function, f (x) = x2?

Answers

9514 1404 393

Answer:

  see below

Step-by-step explanation:

We assume your functions are ...

  f(x) = x²

  g(x) = (x -4)² +12

_____

You need to be able to recognize that g(x) matches a pattern:

  g(x) = f(x-h) +k

where h = 4, and k = 12.

In this pattern, the value of h is the number of units the graph is translated to the right. The value of k is the number of units the graph is translated up.

So, g(x) is the same as the graph of f(x), but translated 4 units right and 12 units up.
