Answer:
14.4
Step-by-step explanation:
x=18
if x=4 then y=5
18/5= 3.6
therefore x= 4 times 3.6 or 14.4
2. A circle with a radius of 10cm has a circumference of...?
3. Calculate a circumference of a circle with a diameter of 13cm.
4. A circle has a diameter of 9.5cm.What is the distance around the circle?
How do you calculate the circumference of a circle?
When would you use 2nr?
When would you use nd?
Come up with your own examples(at least two) to show how to calculate the circumference of a circle.
1. The circumference of a circle is 2πr, and when we plug in 3 for r, we get 6π.
2. We'll use the same formula and plug in 10 for r, giving us 20π.
3. The formula we use in this case is πd, and when we plug in 13 for d, we get 13π.
4. Same formula from 3, we plug in 9.5 for d and get 9.5π.
5. You can calculate the circumference of a circle using 2 formulas, C=2πr (where r=radius and C=circumference) and C=πd (where d=diameter and C is circumference).
6. You use 2πr when the radius is given.
7. You use πd when the diameter is given.
8. 2 examples could be to use the 2 formulas.
Answer: 11,600 Mexican pesos
Step-by-step explanation:
To determine how many pesos you can buy with $580, you need to know the current exchange rate between the US dollar (USD) and the Mexican peso (MXN). Exchange rates fluctuate, so it's important to check the most up-to-date rate.
Let's assume that the current exchange rate is 1 USD = 20 MXN.
To calculate how many pesos you can buy, you would multiply the amount of dollars you have by the exchange rate:
$580 * 20 MXN/USD = 11,600 MXN
Therefore, with $580, you can buy 11,600 Mexican pesos (MXN). Please note that exchange rates may vary, so it's always a good idea to check the current rate before making any conversions.
If |x| > 5, then x > 5 is true.
If the absolute value of x, denoted |x|, is greater than 5, then x must be either greater than 5 or less than -5. This is because the absolute value of a number is its distance from zero on the number line, so any number that is more than 5 units away from zero will be greater than 5 or less than -5.
In this case, we are looking for x to be greater than 5, so the statement x > 5 is true.
