it is 140° Bc angle S and Z should add up to 180
Answer:
≈ 30.63 cm²
Step-by-step explanation:
The shaded area is calculated by subtracting the area of the inner circle from the area of the outer circle.
outer circle has radius = 8 ÷ 2 = 4 and inner circle has radius = 5 ÷ 2 = 2.5
shaded area = πr₁² - πr₂² (r₁ is outer and r₂ is inner )
A = π (4² - 2.5²)
= π(16 - 6.25) = 9.75π ≈ 30.63 cm²
Answer:
Okay, so a bit of math is involved, along with steps.
Step-by-step explanation:
Kyra invested $400 at 3% for 3 years. meaning 3% of $400 is 12. 400+12=
Year 1: $412
3% of 412=12.23+412=
Year 2: $424.23
3% of 424.23=12.7+423.23=
Year 3: $435.93
Kyra made $35.93 in investments.
Lishsawn invested $500 at 4% for 2 years. Meaning, 4% of $500 is 20. 500+20
Year 1: $520
4% of 520=20.8+520
Year 2: $540.8
Lishawn made $40.8 dollars in investments. Meaning that Lishawn made $4.87 more dollars
Hello,
The excluded values are the roots of the denominator.
x²-7x+10=x²-2x-5x+10=x(x-2)-5(x-2)=(x-2)(x-5)
Roots of the denominator are x=2 and x=5
