I need you guys to check if im correct! if not, show me step by step explanations

● Answer:

b) 24 cm

● Step-by-step explanation:

l + 4 = 2w => l = 2w - 4

5w + 6 = P => 5w + 6 = 2w + 2l

5w + 6 = 2w + 2(2w - 4)

5w + 6 = 2w + 4w - 8

6 + 8 = 6w - 5w

w = 14

l = 2x14 - 4

l = 28 - 4

l = 24 cm

How many multiples of 9 are there between 100 and 2,000?
Marat540 [252]
First of all, find the first number more than 100 that can divided by 9, and it's 108 (we'll call it as 'a') then, find the number less than 2000 that can divided by 9, it's 1.998 (we'll call it as 'Un')

Un = a + (n-1).b
1998 = 108 + (n-1).9
1998 = 108 + 9n -9
1899 = 9n
211 = n

and the total is
Sn = n/2 (a+un)
s211 = 211/2 (108+1998)
= 222.183

An island is 3 kilometers due north of its closest point along a straight shoreline. A visitor is staying in a tent that is 13 k
spin [16.1K]

Answer:

The visitor should run 13 km due west from the tent

Step-by-step explanation:

Here we have;

Location of island = 3 km North of point on shoreline

Location of tent = 13 km East of point on shoreline

Running speed of visitor = 8 km/h

Swimming speed = 1 km/h

Distance of island from tent = \sqrt{3^{2} + 13^{2}  } = 13.34 km

Since, time = distance/speed, it will take 13.34/1 hours or 13.34 hours to swim directly to the island.

However if the visitor first runs to the closest point on the shoreline to the island, then swims across to the island, it will take;

13/8 Hr + 3/1 hr = 37/8 hours or 4.625 hours only.

Therefore, to minimize the time it takes to reach the island, the visitor has to run 13 km west of the tent to first get to the closest point of the shoreline to the island before swimming across to the island.
