A plumber had two pipes. The ratio of the length of the longer pipe to the

expeople1 [14]

Answer:

4.95m

Step-by-step explanation:

Let the length of longer and shorter pipe be x and y respectively..

given,

x/y=9/2...(i)

x-1.65=3y ...(ii)

in eqn ii..

x-1.65=3y

or, x/y - 1.65/y = 3

or, 9/2-1.65/y =3

or, 4.5-3 = 1.65/y

or, y=1.65/1.5

•°• y = 1.1m

now,

x/y = 9/2

or, x/1.1 = 4.5

x= 4.5×1.1

•°• x= 4.95m

thus, the length of the longer pipe is 4.95m

Does anybody know the answers to these? will mark brainliest!

jeyben [28]

Answer:

Tan 45=√2/n

n=√2

again

sin 45=√2/m

m=2

answer: m=2,n=√2

2.

sin 45=x/3

x=3/√2=3√2/2

y=3√2/2

ans:x=3√2/2,y=3√2/3

3.

sin 45=a/4

a=4/√2

b=4/√2

ans:a=4/√2,b=4/√2

b=4 base sides of isosceles triangle

sin 45=4/a

a=4√2

ans:a=4√2 and b=4

A. 12 b. 14 c. 8 d. 6

jolli1 [7]

Answer:

d. 6

Step-by-step explanation:

The product of lengths to the near and far intersection points is the same for both secants:

PB×PA = PD×PC

We can use this relation to solve for x, then use the value of x to find PD.

7×12 = (3x)(7x)

4 = x² . . . . . . . . . divide by 21

2 = x . . . . . . . . . . take the square root

PD = 3x = 3·2

PD = 6

A) x = 26, y =11 B) x = 13, y = 24 C) x = 11, y =26 D) x = 24, y = 13

zepelin [54]

Answer:

A) x=26, y=1

Step-by-step explanation:

parallelograms have equal lengths on opposite sides. in this picture, y is alone. Opposite of that, the length is 11. so y must be 11. the only choice there is A.
