Okay this is simple once you get use to it. What you first need to do is figure out the formula. I don’t have a calculator on me so I will just tell you the formula so you can get the answer
: 1/3 times 8 times 6 times 10
Answer:
The best option would be Number 1.
Step-by-step explanation:
Let's say that they each traveled 1,000 miles a week, meaning that instead of the SUV using 100 gallons of gas, it would be using 90.9, which is 9.1 gallons less.
The hybrid will only use 20 gallons of gas in that week. Meaning together, they will be 100.9 gallons a week for 1,000 miles.
In option 2, they would still be using 100 gallons of gas for the SUV a week, except, the hybrid would only be using 12.5 gallons, which is 7.5 gallons less.
The total of those together would be 112.5 gallons a week for 1,000 miles. So, it may be a small difference between the two options, yet Option 1 is the best choice on how to save gas.
area of the pond is 50*50 = 2500 square meters
the walkway is 5 meters wide so the outside dimensions would be 60 meters by 60 meters
area of that is 60 *60 = 3600 meters
area of walkway is 3600 - 2500 = 1100 square feet
number of crates needed: 1100 / 45 = 24.44, round up to 25 crates
25 crates x $74 each = $1,850 total
Answer:
a) 14,1 cm
Step-by-step explanation:
If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.
We use Pytagoras Theorem to find out the length (L) of the diagonal given that:
L² = (20)² + (20)²
L² = 2* (20)²
L = √2 * 20
L = 1,4142* 20
L = 28,28 cm
L diagonal in the square is a diameter of the circle then radius of a circle is:
r = L/2 ⇒ r = 28,28 /2 ⇒ r = 14,14 cm
I think it’s 24 I could be wrong but I’m pretty sure
