A mountain in boone county is eroding and losing elevation at a rate of 5% every millennium. if the current elevation is 1,710 m
aliina [53]

Answer: 1,393 meters tall

Step-by-step explanation:

Plug in 1710 meters for the initial amount, 0.05 for the rate of decrease, and 4 millennia for the time elapsed.

y

= a(1–r)t

y

= 1,710(1–0.05)4 Plug in values

y

= 1,710(0.95)4 Subtract

y

= 1,710(0.81450…) Simplify

y

= 1,392.80568… Multiply

Round to the nearest whole number.

1,392.80568… → 1,393

To the nearest whole number, the mountain will be 1,393 meters tall.

A mural of Elvis Presley takes 56 days to complete by seven painters 28 volunteers join the team after the first six days how ma
denpristay [2]

Answer:

10 days

Step-by-step explanation:

We are given that

Each person takes 56 days

7 painters take time=56\times 7=392 painter days

In first 6 days , 7 painters take time=7\times 6=42painter days

After 6 days , 28 volunteers are added then,

Total persons=28+7=35

Now, remaining days=392-42=350

Therefore, number of days are required before the painting of the king of rock 'n' roll is completed=\frac{350}{35}=10days

Hence,10 more days are required before the painting of the king of rock 'n' roll is completed

If n(A-B)=18,n(AuB)=70 and n(AnB)=25 then find n(B)
svp [43]

n(A-B) denotes elements which are in A but not in B

n(Au B) denotes elements in A and B

n(AnB) denotes elements that are common in A and B

Now I will add one more set

n(B-A) which denotes elements in B but not in A

So, n(AuB) = n(A-B) + n( B-A) +n(AnB)

70 = 18 +n(B-A) + 25

70 = 43 + n(B-A)

n(B-A) = 70-43

n(B-A) = 27

So, n(B) = n( B-A) + n( AnB)

= 27+25

= 52
