Answer:

48,24,30

Step-by-step explanation:

Let, the length of second side be x

A/c to question,

first side (a) = 2x

second side (b) = x

third side (c) = x + 6

Perimeter of ∆ (p) = 102

And,

Perimeter of ∆ = a + b + c

102 = 2x + x + x + 6

102 - 6 = 4x

96 = 4x

x = 96/4

x = 24

Now,

first side = 2*24 = 48

second side = 24

third side = 24 + 6 = 30

Step-by-step explanation:

Formula~ 1/2*b*h

1/2*15*b=120

7.5b=120

b=120/7.5

Which fraction is equivalent to 38%?<br> 3/8<br> 9/25<br> 19/50<br> 3 4\5
KonstantinChe [14]
In order to find a fraction, We know that a percentage is out of a 100. This means we can now place our fraction as:

38/100

In order to find the actual fraction, we will want to simplify. Lets find our least common factor and work down from there. Since we know that 2 can go into both of them, lets reduce by 2.

This means our fraction will now look like: 

19/50

Since 19 is a prime number and cannot be divided by anything but 1 and itself, we know that this is our simplified form. 

This means:

19/50 is the fraction equivalent to 38%.

You are painting the root of a boathouse. You are going to place the base of a ladder 12 feet from the boathouse. How long does
jolli1 [7]

Answer:

37 ft

Step-by-step explanation:

The ladder forms a right triangle as it elan's against the wall of the boat house.

Thus, the length of the ladder can be determined using Pythagorean theorem.

c² = a² + b²

c = length of ladder

a = 35 ft

b = 12 ft

Plug in the values

c² = 35² + 12²

c² = 1,225 + 144

c² = 1,369

c = √1,369

c = 37

Therefore, to reach the roof of the boathouse, the length of the ladder = 37 ft
