What is the least common multiple between 8 10 and 12

1 answer:

3 0

The LCM is the lowest number that is a multiple of all three numbers.
First, list the multiples of each number
8: 8, 16, 24, 32,40 48, 56, 64, 72, 80, 88, 96, 104, 112, 120
10: 10, 20, 30 40, 50, 60, 70, 80, 90, 100, 110, 120
12: 12, 24, 36, 48, 60, 72, 84, 96, 108, 120

The LCM is 120 because there is no lower number that is a multiple of all three numbers.
Hope this helped!

HI can you help me with this question

Answer:

42 square centimeters

Step-by-step explanation:

The total of sides FA and AB will be half the perimeter of the rectangle, or 14 cm. Since AB is 9 cm, that means FA is 5 cm.

EF is the difference between EF and FA, so is 11 cm -5 cm = 6 cm.

FC is the same 9 cm length as AB, so we have enough information about the trapezoid to use the area formula:

A = (1/2)(b1 +b2)h

A = (1/2)(9 cm +5 cm)(6 cm) = 42 cm^2

The area of the trapezium is 42 cm^2.

Answer:

See below ↓↓↓

Step-by-step explanation:

Subquestion #1

These angles form a linear pair
They are supplementary, and add up to 180°
2x + 48 = 180
2x = 132
x = 66

Subquestion #2

These angles are complementary, and add up to 90°
35 + 4x + 7 = 90
4x + 42 = 90
4x = 48
x = 12

Subquestion #3

As in #1, they are a linear pair, and are supplementary
3x + 54 = 180
3x = 126
x = 42

A trail around a river is 3 1/4 miles long. What is the length, in feet, of the trail?

bezimeni [28]

Answer: 17160 feet

Step-by-step explanation:

We know that 5280 feet = 1 mile

So all we have to do is multiply 3 1/4 by 5280

Let's split the 3 and 1/4 up to make the multiplication easier

3×5280=15840

$\frac{1}{4}$ ×5280= $\frac{5280}{4} =1320$

Now add them together

15840+1320=17160
