Describe the sounds, smells, and sights you associate with spring. Write a paragraph with at least 4 sentences.

spin [16.1K]

Smell: Spring brings soothing scents like lilacs, apple blossoms, hyacinth and daffodils. Sweet aromas turn a stroll through the garden into a delicacy for the nose Springtime means that the trees and flowers come back to life again. After a dead winter, this is a time when we get to see the beautiful flowers blossom again Spring also brings new sounds, like bird songs at dawn, frog croaks by ponds, and dripping icicles. When the weather warms, the sounds you hear in national parks reflect this seasonal change (use this but not in this order fix it up a bit)

Rewrite the equation from step 1 substituting in the value of.

Masteriza [31]

By rewriting the equation from step 1 substituting the value of k into it, the value of x is 22.5

A direct variation is a type of variation that has two types of variables in which a variable can be expressed in terms of the other with its constant.

For example;

If x varies directly as y

Then

x $\sim$ y
x = ky ; where k is constant

The original question says:

if x varies directly as y, and x = 9 when y = 6, find x when y = 15

∴

x = ky

9 = k × (6)

k = 9/6

k = 1.5

Now, we can rewrite the equation from step 1 substituting the value of k into it:

∴

x = ky

when y = 15 and k = 1.5

The value of (x) will be:

x = 1.5 (15)

x = 22.5

Misha Larkins [42]

The program is an illustration of a sequential structure

<h3>What are sequential control structures?</h3>

Sequential control structures are programs that do not require loops and conditional statements

<h3>The actual program</h3>

The program in Python where comments are used to explain each line, is as follows:

#This gets input for age

age = int(input("Age: "))

#This gets input for weight

weight = (input("Weight: "))

#This gets input for the heart rate

heartRate = float(input("Heart Rate: "))

#This gets input for the time

time = int(input("Time: "))

#This calculates the calories burnt

calories = ((age * 0.2757) + (weight * 0.03295) + (heartRate * 1.0781) - 75.4991 ) * time / 8.368

#This prints the calories burnt

print('calories: {:. 2f} calories'. Format(calories))
