Answer: The expression, 8 x 54, may also be expressed as 8 x 50 + 8 x 4 because by factoring the 8,
8 x (50 + 4) = 8 x 54
Further, it can also be expressed as,
8 x 60 - 8 x 6
because,
8 x (60 - 6) = 8 x 54
Step-by-step explanation:
HEY THERE !!
As we know that the area of a circle (A)= πr^2
But if we know the diameter then the area is (A)= π/4× D^2 { here D is for diameter}
Here diameter is 10.5 inches.
A => π/4 × (10.5)^2
A => π/4 × 110.25
A => π/4 × 27.5625
A => 86.54625 { because the value of π = 3.14}
So the area of the cirsle whose diameter is 10.5 inches is 86.54625 inches square.
HOPE IT HELPED YOU.
Answer:
1.) y = 1.10(x – 1) + 1.35
Step-by-step explanation:
When x pounds of apples are purchased, the number of "additional" pounds is (x-1). The cost of those additional pounds is then added to the cost of the first pound to get ...
y = 1.10(x -1) +1.35
_____
<em>Comment on the function rule</em>
Personally, I think it is easier to write the rule as y = 1.10x +0.25, considering the first pound to have a $0.25 premium added to its otherwise $1.10 cost. This saves an operation when evaluating the formula for some value of x.
