Answer:
Step-by-step explanation:
Divide the numbers and write what you got in distributive property
10 pairs :)
2 rows= 3 pairs touching 4 columns= 1
2*3+4*1=10
16.4 ÷ 10 = 1.64
The easiest way to divide decimals by 10 is to move the decimal point by one place to the left. It's the same if you divide by 100, but in that case you move it by two places. It's also similar with 1000, 10000 etc...
It also applies to multiplying, but in such situation you move the decimal point to the right.
Answer:
9 ft, 28 ft, 26 ft
Step-by-step explanation:
The perimeter is the sum of side lengths, so ...
P = a + b + c
63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths
63 = 7n . . . . . . simplify
9 = n . . . . . . . . divide by 7
4n -8 = 36 -8 = 28 . . . . second side length
2n +8 = 18 +8 = 26 . . . . third side length
The side lengths are 9 ft, 28 ft, 26 ft..
Answer:
10 cm
Step-by-step explanation:
The volume of the cylinder is 1884 cubic centimetres and its height is 6 cm.
The volume of a cylinder is given as:
where r = radius
h = height
To find the radius of the base of the cylinder, we make r the subject of the formula and solve it:
Divide both sides by πh:
Find the square root of both sides:
Let us find the value of r:
=> r = 9.9975 cm ≅ 10 cm
