A playing card has an area of 50 square centimeters and a perimeter of 30 centimeters. What are the dimensions of the playing card?

Answers

The dimensions of playing card is L = 10 centimeter and W=5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.

Step-by-step explanation:

The given is,

                  Playing card has an area of 50 square centimeters

                  A perimeter of 30 centimeters

Step:1

                 A playing card is in the shape of rectangle,

                 Formula for perimeter of rectangle is,

                                      [tex]Perimeter, P = 2(l+w)[/tex] .........................(1)

                 Formula for area of rectangle is,

                                             [tex]Area, A= lw[/tex]......................................(2)

                  Where, l - Length of rectangle

                             w - Width of rectangle

Step:2

                From the given values equation (1) becomes,

                                                       [tex]30 = 2(l+w)[/tex]              

                                                       [tex]\frac{30}{2}=(l+w)[/tex]      

                                                       [tex]15 =(l+w)[/tex]

                                                       [tex]w=15-l[/tex]  .............................(3)

                Width value in terms of length is calculated.

Step:2

                Equation (2) becomes,

                                                      [tex]50 = (15-l)(l)[/tex]

                                                      [tex]50= 15l -l^{2}[/tex]

                                      [tex]l^{2}-15l+50=0[/tex]

              Solving the above equation,

                                                          [tex]=10[/tex]

                                                       [tex]l=10 cm[/tex]

Step:3

                 Equation (3) becomes,

                                                       [tex]w=15-l[/tex]

                                                           [tex]=15-10[/tex]

                                                           [tex]=5[/tex]

                                                     w = 5 cm

Result:

           The dimensions of playing card is L = 10 centimeter and W = 5 centimeter, If the playing card has an area of 50 square centimeter and a perimeter of 30 centimeters.

Final answer:

By creating an equation system using the area and perimeter formulas for a rectangle, the dimensions of the playing card are found to be either 5 cm by 10 cm or 10 cm by 5 cm.

Explanation:

To determine the dimensions of a playing card given its area and perimeter, we need to set up an equation system based on the properties of a rectangle. Let's call the length L and the width W. The area (A) of a rectangle is A = L × W, which in this case is 50 sq cm. The perimeter (P) is P = 2(L + W) and is given as 30 cm.

From the perimeter, we can rearrange this to find L in terms of W:
30 cm = 2(L + W)
15 cm = L + W
L = 15 cm - W

Now, substituting L in the area equation gives us:
50 cm² = (15 cm - W) × W
This can be rearranged to form a quadratic equation:

0 = W² - 15W + 50

Factoring, we find:
0 = (W - 5)(W - 10)
So we have two solutions, W = 5 cm or W = 10 cm.

If we take W as the width, then L (the length) would be the other dimension, which would be 15 cm - W. So, we have two possible dimension pairs based on the standard card size: (5 cm by 10 cm) or (10 cm by 5 cm).

Find the length of a pendulum that makes one swing in 3 s. The equation for the time of one swing of a pendulum is T= 2pi sqrt(L/32) , where T is the time in seconds and L is the length in feet. Round to the nearest hundredth.

Answers

Answer:

7.30

Step-by-step explanation:

T = 2π √(L/32)

3 = 2π √(L/32)

3/(2π) = √(L/32)

(3/(2π))² = L/32

L = 32 (3/(2π))²

L ≈ 7.30

The length of the pendulum in feet nearest to hundredth is 7.29 feet.

What is an equation?

Two algebraic expressions having same value and symbol '=' in between are called as an equation.

Given that the equation for the time of one swing of a pendulum is

T = 2π √(L/32).

And pendulum makes one swing in 3 seconds.

Now T is 3 second.

So , substituting the value of T in given expression;

3 = 2π √(L / 32)

3 / (2π) = √(L / 32)

Taking square on both sides,

{ (3/(2π) }² = L / 32

L = 32 × { 3 / (2π) }²

L = 7.295

L ≈ 7.29

Therefore, the length of the pendulum in feet nearest to hundredth is 7.29 feet.

Find log 47.2 to four decimal places.

Answers

Step-by-step explanation:

log 47.2 in four decimal places

= 1.6739

Final answer:

To find log 47.2 to four decimal places, use the logarithmic function. The result is approximately 1.6739

Explanation:

To find log 47.2 to four decimal places, we need to use the logarithmic function. The logarithm function is the inverse of exponentiation. In this case, we are looking for the logarithm of 47.2.

Using a scientific calculator or logarithmic tables, we can find that log 47.2 ≈ 1.6739 to four decimal places.

The four decimal places are determined by the precision of the logarithm function and the number of significant figures in the input value (47.2 has four significant figures).

The Fibonacci sequence is the sequence 1, 1, 2, 3, 5, ... where the first and second terms are 1 and each term after that is the sum of the previous two terms. What is the remainder when the 100th term of the sequence is divided by 8?

Answers

Final answer:

The remainder when the 100th term of the Fibonacci sequence is divided by 8 is 3.

Explanation:

The Fibonacci sequence is a sequence where each term is the sum of the previous two terms. The sequence starts with 1, 1, and then continues with 2, 3, 5, and so on. To find the remainder when the 100th term of the sequence is divided by 8, we can calculate the terms of the sequence modulo 8 until we reach the 100th term.

First term: 1 mod 8 = 1Second term: 1 mod 8 = 1Third term: (1 + 1) mod 8 = 2Fourth term: (1 + 2) mod 8 = 3Fifth term: (2 + 3) mod 8 = 5Sixth term: (3 + 5) mod 8 = 0Seventh term: (5 + 0) mod 8 = 5Eighth term: (0 + 5) mod 8 = 5Ninth term: (5 + 5) mod 8 = 2Tenth term: (5 + 2) mod 8 = 7

We can see from the pattern that the terms modulo 8 repeat every 6 terms. Therefore, to find the remainder when the 100th term is divided by 8, we can calculate the remainder when 100 is divided by 6. 100 mod 6 = 4. So, the remainder when the 100th term of the Fibonacci sequence is divided by 8 is the same as the remainder when the 4th term is divided by 8, which is 3.

Answer:

Answer C.12

Step-by-step explanation:

v/V=(h/H)^3

1/8=(h/24)^3

1/8=h^3/24^3

1/8=h^3/13824

8h^3=13824

H=1728√3

h= \sqrt[3]{1728}

h=12 cm

the height of the smaller pyramid is 12 inches.

What is a triangular pyramid?

A triangular pyramid is a 3D geometric shape in which all the three lateral faces are triangles with a common vertex. If all the three triangular faces are equilateral, then such a pyramid is called a tetrahedron.

For the given situation,

The ratio of the volumes of two geometrically similar pyramids = 1:8

The height of the larger pyramid = 24 inches.

Let the volume of smaller pyramid be v1 and larger pyramid be v2.

Let the height of smaller pyramid be h1 and larger pyramid be h2.

The relation between the volume of pyramid and height is given as

[tex]v=\frac{1}{3} (base area)(height)[/tex]

Let us consider the triangle to be equilateral triangle. So all the sides are equal.

We know that, Base area = [tex]a^{2}[/tex] and [tex]a=h[/tex]

The volume becomes [tex]v=\frac{1}{3} h^{3}[/tex]

The ratio becomes,

⇒ [tex]\frac{v1}{v2} =\frac{h1^{3} }{h2^{3}}[/tex]

⇒ [tex]\frac{1}{8} =\frac{h1^{3} }{24^{3}}[/tex]

⇒ [tex]h1^{3}=\frac{24^{3} }{8}[/tex]

⇒ [tex]h1^{3}=\frac{13824 }{8}[/tex]

⇒ [tex]h1^{3}=1728[/tex]

⇒ [tex]h1=\sqrt[3]{1728}[/tex]

⇒ [tex]h1=12[/tex]

Hence we can conclude that the height of the smaller pyramid is           12 inches.

From Winning Team Shoes, the cost of 11 pairs of soccer shoes is $825 plus an additional 6% for each additional pair. For how many total pairs of soccer shoes does each vendor cost about the same? Write the equations

Answers

Final answer:

Both vendors cost about the same for 20 pairs of soccer shoes.

Explanation:

For Sports Shoe Warehouse, the cost for 11 pairs is $1100, and each additional pair costs $66. So, the total cost for x additional pairs would be $1100 + $66x.

For Winning Team Shoes, the cost for 11 pairs is $825, and each additional pair costs 6% more than the previous pair. So, the total cost for x additional pairs would be $825 + 0.06(825)x.

To find when both vendors cost the same, we set their expressions equal: $1100 + $66x = $825 + 0.06(825)x. Solving for x gives x = 20. Therefore, both vendors cost about the same for 20 pairs of soccer shoes.
