35! Because the common factors of 7 are 7,14,21,28,35 and the common factors of 5 are 5,10,15,20,25,30,35 so it’s 35!!
Answer:
240
Step-by-step explanation:
you do 3x10 which is 30 then multiply that by 8 and you have your answer.
Answer: true
Step-by-step explanation: because i learned last year in my accelerated math class about this and we did a quizlet on it and it had a question like that on the quiz.
You can make the equilateral triangle into a right triangle by cutting it in half. So, your sides would be 4.5, 9, and x.
Using Pythagorean Theorem, you know that a^2 + b^2 = c^2.
The 'a' would be equal to 9, and 9^2 is equal to 81.
B is equal to 4.5, and 4.5^2 is 20.25.
So, you have the following:
81 + 20.25 = c^2
And that makes 'c' equal to 101.25.
The square root of 101.25 is approximately equal to 10.06.
So now you know the height, 10.06.
The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.
If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.
Answer:
18 ft
