The smallest number is .0082.
A decrease in the ratio 4:5 implies that :
New quantity:Old quantity = 4:5
Let the new quantity be
So, the new quantity is 32
Answer:
$10.50
Step-by-step explanation:
The equation would start off as 40x+4(1.5x)=483. Simplify from there, 40x+6x=483 -> 46x=483-> x=10.5
The coefficient of 2(3)(6)Q is 2(3)(6)
<h3>How to determine the
coefficient?</h3>
The expression is given as:
2(3)(6)Q
For an expression
AQ
Where A is a number or product of numbers and Q is a variable
The number A represents the coefficient
By comparing:
AQ and 2(3)(6)Q
We have
A = 2(3)(6)
Hence, the coefficient of 2(3)(6)Q is 2(3)(6)

Answer:
7 packets of grass seed
Step-by-step explanation:
First, find the area of the circular lawn using the formula, A = r²
If the diameter is 20 meters, the radius is 10 meters.
Plug in 10 as the radius and solve for the area:
A = r²
A = (10²)
A = 100
So, the area of the lawn is 100 m² or approximately 314.16 m²
Divide this by 50 to find how many packets of grass seed are needed:
314.16/50
= 6.28
Round this up to 7, since we need to have a whole number answer.
So, 7 packets of grass seed have to be bought.
