Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

Answer:

Step-by-step explanation:

a deli wraps its cylindrical containers of hot food items with plastic wrap. the minimum amount of plastic wrap needed to completely wrap 8 containers is: 785.4 square inches.

What is the minimum amount of plastic wrap needed?

The area of each circular end is:

A = πr^2

where r is the radius of the end. The diameter of each container is given as 5.5 inches, so the radius is half of that, or 2.75 inches. Using π = 3.14, we get:

A = 3.14 * (2.75in)^2

A = 23.68in^2 (rounded to two decimal places)

The area of the rectangular side is:

A = h * circumference

where h is the height of the container and circumference is the distance around the circular end. The circumference is equal to the diameter times π, so we have:

circumference = 5.5in * π

circumference = 17.27in (rounded to two decimal places)

Using the given height of 3 inches, we get:

A = 3in * 17.27in

A = 51.81in^2 (rounded to two decimal places)

Therefore, the total surface area of each container is:

A = 2 * 23.68in^2 + 51.81in^2

A = 98.17in^2 (rounded to two decimal places)

To wrap 8 containers, we need to multiply the surface area of each container by 8:

total surface area = 8 * 98.17in^2

total surface area = 785.36in^2 (rounded to two decimal places)

Therefore, we need a minimum of 785.36 square inches of plastic wrap to completely wrap 8 cylindrical containers of hot food items. Rounding to the nearest tenth, the answer is 785.4 square inches.

Answer: 90 seconds or 1.5 minutes

Step-by-step explanation: 2 minutes(120 seconds) divided by 4 edges equals 30 seconds per edge. To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds

The time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a fly can walk around a cubical block in two minutes.

The time taken to cover all the one edge is,

T = 120 / 4

T = 30 seconds

To get from 1 corner to the diagonally opposed opposite corner the fly would walk on 3 edges, so it would take 90 seconds. Mathematically written as,

To = 3 x 30

To = 90 seconds

To = 1.5 minutes

Therefore, the time taken to cross from one corner to another diagonally is 90 seconds or 1.5 minutes.

Answer:

given with two conditions: after 0 degrees Celsius, this is equal to 32 degrees Fahrenheit and after at 100 degrees Celsius, this is equal to 212 degrees Fahrenheit . We translate these into points, we have (0,32) and (100, 212). we get the slope of the points ((212-32)/100) or 9/5. we plug to the equation y-y1 = m (x-x1) where m is equal to 9/5. y-32 = 9/5 (x-0). Simplifying, we get y -32 = 9x/5 or equal to y = 9/5 x + 32 where x is degrees Celsius and y is degrees Fahrenheit.

hope this helps

The given temperature is required in Fahrenheit.

The required temperature is 77 degrees Fahrenheit.

Let the x axis denote Celsius

and y axis denote Fahrenheit

The ordered pairs are \((100,212)\) and \((0,32)\)

The equation of the line will be

\(y-212=\dfrac{32-212}{0-100}(x-100)\\\Rightarrow y-212=1.8(x-100)\\\Rightarrow y-212=1.8x-180\\\Rightarrow y=1.8x+32\)

The temperature is 25 degrees Celsius so \(x=25\)

\(y=1.8\times 25+32\\\Rightarrow y=77\)

The required temperature is 77 degrees Fahrenheit.

Answer: 22.5 pounds

Step-by-step explanation:

The computation of the weight of the block of gel is shown below:

As we know that

Volume = (length) (width) (height)

= (20) (6 ) (6)

= 720 cubic inches 

Now we have to convert into cubic foot

As we know that

1 ft = 12 inches

So 1ft^3 = 12 inches^3

= 1728 inches ^3
Now

= 720 × 1 cubic foot ÷ 1728 cubic inches

= 5 ÷ 12

Now the weight is = 54 × 5 ÷ 12=

:)

Step-by-step explanation:

Answer:

3/4

Step-by-step explanation:

Since (p, r) lies on the line y = x + b,

we have,

r = p + b -----eq(1)

Since (2p, 5r) lies on the line y = 2x + b,

we have,

5r = 2(2p) + b -----eq(2)

Sub the value of r from eq(1) in eq(2),

5(p + b) = 4p + b

⇒ 5p + 5b = 4p + b

⇒ 5b - b = 4p - 5p

⇒ 4b = -p

⇒ b = -p/4

sub in eq(1)

r = p + (-p/4)

= p - p/4

= 3p/4

⇒ r = 3p/4

⇒ r/p = 3/4

Answer:

3/4

Step-by-step explanation:

We have two lines:

r = p + b     eq(1)

5r = 4p + b   eq(2)

eq(2) - eq(1)

4r = 3p

dividing by 4p

r/p = 3/4
