Mathematics
1 answer:
Nastasia [14]3 years ago
4 0

Answer:

6

Step-by-step explanation:

From the pythagorean theorem the square lenght of hypotenuse is equal to sum of square lenght of base and side

(6.5)^2 = x^2 + (2.5)

42.25 = x^2 + 6.25 subtract 6.25 from both sides

36 = x^2 and x = 6

For a right circular cylinder, if the radius is tripled and the height is shrunk down to half its size, then what is the surface
Elden [556K]

The surface area of a cylinder that the radius tripled and it height is brought down to half is 3890.46 inches²

<h3 /><h3>How to find the surface area of a cylinder?</h3>

Surface area of a cylinder = 2πr(r + h)

Therefore,

radius is tripled = 3(7) = 21 inches

height is shrunk half its size = 17 / 2 = 8.5 inches

Therefore,

surface area = 2 × 3.14 × 21 (21 + 8.5)

surface area = 131.88(29.5)

surface area = 3890.46 inches²

PLEASE HELP!
nikklg [1K]

A: The other related equations would be:

K = °C + 273.15

K = °F + 457.87

<em>Note: There are other equations that can be related, these are just ones that I find to be related. This is open to interpretation. </em>

B:

23° C + 273.15 = 269.15 K

C:

300 K - 273.15 = 26.85 °C

300 Kelvins is greater than 25 degrees Celsius.

Write 0.46 as a fraction in simplest form
butalik [34]
Here's how to convert 0.46 to a fraction...

There is not much that can be done to figure out how to write 0.46 as a fraction, except to literally use what the decimal portion of your number, the .46, means.

Since there are 2 digits in 46, the very last digit is the "100th" decimal place.

So we can just say that .46 is the same as 46/100. The fraction is not reduced to lowest terms. We can reduce this fraction to lowest
terms by dividing both the numerator and denominator by 2.

Why divide by 2? 2 is the Greatest Common Divisor (GCD)
or Greatest Common Factor (GCF) of the numbers 46 and 100.
So, this fraction reduced to lowest terms is 23/50

So your final answer is: 0.46 can be written as the fraction 23/50

The mean of 12 numbers is 20 and the mean of another 8 numbers is 25 find the mean of the 20 numbers
AysviL [449]

Answer:

22

Step-by-step explanation:

mean is calculated as

mean = \frac{sum}{count}

Given the mean of 12 numbers is 20 , then

\frac{sum}{12} = 20 ( multiply both sides by 12 )

sum = 240

Given the mean of 8 numbers is 25 , then

\frac{sum}{8} = 25 ( multiply both sides by 8 )

sum = 200

Total sum of the 20 numbers = 240 + 200 = 440, then mean of 20 numbers is

mean = \frac{440}{20} = 22
