Answer:
The Probability is 63.7%
Step-by-step explanation:
We need to calculate the area of the circle and the area of the square
From the question, we can see that the square is of side 4 √2 cm
The area of the square is simply the square of its side length
We have this as 4√2 * 4√2 = 16 * 2 = 32 cm^2
The area of the circle can be calculated using the formula for the area of a circle, with the radius being 4 cm
So, we have the area of the circle as;
Pi * r^2
= 22/7 * 4 * 4 = 50.3 cm^2
so, to find the probability, we need to divide the area of the circle by the area of the square
we have this as;
32/50.3 = 0.6366
In percentage, we simply multiply by 100% to give
0.6366 * 100% = 63.66%
To the nearest tenth, this is 63.7%

Answer:
18 lawns
Step-by-step explanation:
Expected sum = $515
Bonus for 1 day = $15
Bonus for 5 days = $15 × 5 = $75
Amount to be earned from mowing lawns in 5 days = $515 - $75 = $440
$25 ≡ 1 lawn
$440 ≡ 440 ÷ 25 = 17.6
The minimum number of lawns is 18.
<em>(Note that we take the minimum integer greater than 17.6. If he mows 17 lawns, his earning from 17 lawns = $425 + $75 = $500)</em>
Answer:
-31.2x + 28.7y + 10.5
Step-by-step explanation:
Step 1: Write expression
2.5(4.2 + 7.4y) - 3.6(8x - 4.5y) - (2.4x + 6y)
Step 2: Distribute
10.5 + 18.5y - 28.8x + 16.2y - 2.4x - 6y
Step 3: Combine like terms
-31.2x + 28.7y + 10.5
