Renee earns a 15% commission on her $200 sales.
0.15 * 200 = $30
So, she earns 30 dollars from commission.
She also earns $80 a week, which makes a total of 80 + 30 = $110
Hence, the answer is $110
Answer:
66
Step-by-step explanation:
4^3=64
64+2(3-2)
64+6-4 =64+2.
64+2=66
The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
A- the grams of copper is total which is 128 grams.*** b- is the total amount of percent of copper which is 71.76%+9.37
Answer:
e. 1.6π cm²
Step-by-step explanation:
Since the window is in a semi-circular shape, its area A = πD²/4 ÷ 2 = πD²/8 where D = diameter of window = 64 cm
Now, the error in the area dA = dA/dD × dD where dD = error in the diameter = 0.1 cm and dA/dD = derivative of A with respect to D.
So, dA/dD = d(πD²/8)/dD = 2 × πD/8 = πD/4
So, the differential dA = dA/dD × dD
dA = πD/4 × dD
Substituting D = 64 cm and dD = 0.1 cm into the equation, we have
dA = πD/4 × dD
dA = π × 64 cm/4 × 0.1 cm
dA = π × 16 cm × 0.1 cm
dA = π × 1.6 cm²
dA = 1.6π cm²
So, the maximum error in computing the area of the window is 1.6π cm²
