Answer:
6
Step-by-step explanation:
because you list the prime factors of each number then multiply those factors both numbers have in common
The correct answer is 43.3.
Explanation:
When rounding a number, we first find the digit in the place value we're rounding to. In this problem, we are rounding to the tenths place; the digit in the tenths place is 2.
The next thing we do is look at the digit to the right of the place value we're rounding to. If this digit is 5 or more, we round our place value up; if it is 4 or less, we leave our place value alone. The number to the right of the 2 is 9; since this is in the "5 or more" category, we round the 2 up to 3.
The last step is to drop the digits to the right of our place value. This gives us our final answer of 43.3.
Answer/Step-by-step Explanation:
Circumference of a circular object = πd
Where,
π = 3.14,
d = diameter
Circumference of hula pop with diameter of 35 in:
Circumference = πd = 3.14*35 = 109.9 in
Diameter of circular pond with a circumference of 556 ft:
556 = 3.14*d
Divide both sides by 3.14
556/3.14 = d
177.07 = d
d ≈ 117 in
Circumference of magnifying glass with a diameter of 5.2 in:
Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm
Diameter of car tire with a circumference of 71.6 in:
71.6 = 3.14*d
Divide both sides by 3.14
71.6/3.14 = d
22.80 = d
d ≈ 22.8 in
Subtracting 10x from the given equation gives
120 = 15x
Then dividing by 15 gives
8 = x
