Answer:
551.5 cm²
551.5
cm²
Circle area = π * r² = π * 175.5625 [cm²] ≈ 551.5 [cm²]
π ≈ 3.14159265 ≈ 3.14
d = r * 2 = 13.25 [cm] * 2 = 26.5 [cm]
Answer:
75 cents
Step-by-step explanation:
5+5 fifteen times
1) (15+6-5x+4)
= 25-5x
= 5(5-x)
2) (24-10+8x+9)
= 23+8x
Answer:
24,393 subscribers
Step-by-step explanation:
This is <u>exponential decay</u> problem. The formula for exponential decay is:
Where
F is the future value (what we are looking for, in 7 years)
P is the present amount (that is 51,000)
r is the rate of decrease per year (r = 10% = 10/100 = 0.1)
t is the time, in years (t = 7)
Now substituting, we get:
Rounding to nearest whole number,
Number of subscribers after 7 years = 24,393 subscribers
3:1/2 ×(11×4)
=1/2×44
=22m squared(2)
pretty sure double check with the example ur self okey so we make sure
in 1:i think it says to multiply lenght times width (L×W)
so its probably
area=l×w
=6 1/2 × 15 1/2
which when i put in the calculator it gives 45/2
