Answer:
Step-by-step explanation:
270= 3*3*3*2*5 = 3³ * 2 * 5
360= 2*2*2*3*3*5 = 3² *2⁴ * 5
Greatest common factor = 2 * 3² * 5
In this question, there are a few kinds of the coin with a different value. To answer this question, we need to know the total coin first. The total coin count should be: 10 +20 + 15 +5= 50 coin
In this case, the coin is taken twice, that means the denominator should be 50*49. But in this question, the probablity value is 6/49, so you need to convert it into 50*49 by multiplying the numerator with 50. The value should be:
6/49 *50/50= 300/49*50
The number 300 is multiplication of 20 and 15, that mean the answer should be: 1 dimes and 1 nickles
Answer:
1926cm²
Step-by-step explanation:
Given
Dimension = 21cm by 18cn by 15cm
<em>The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:</em>
<em></em>

Where L, B and H are the dimensions.
So,





<em>Hence, 1926 cm² of fabrics are needed to cover all surfaces.</em>

28min/2lawns = 14min per lawn. Then 14min * 5 lawns = 70min
