Answer:

5/18

Step-by-step explanation:

The desired fraction can be found by dividing the fraction of distance by the fraction of hours:

(1/6 distance)/(3/5 hour) = (1/6·5/3) distance/hour = 5/18 distance/hour

Then 5/18 of the distance can be covered in one hour.

\sqrt{2Answer:

Step-by-step explanation:

take 45 degree as reference angle

use sin rule

sin 45=opposite/hypotenuse

1/\sqrt{2=x/2\sqrt{2

do cross multiplication

x\sqrt{2=\sqrt{2 *\sqrt{2

x\sqrt{2=2

x=2/\sqrt{2

x=\sqrt{2

pythagoras theorem

a^2+b^2=c^2

(\sqrt{2 )^2+y^2=(2\sqrt{2 )^2

2+y^2=8

y^2=8-2

y=\sqrt{6

The sum of three numbers is 3. The first number minus the second plus the third is -3. The first minus the third is 1 more than
Rus_ich [418]

<u>Answer:</u> The first number is 2, the second number is 3 and the third number is -2

<u>Step-by-step explanation:</u>

Let the first number be 'x', the second number be 'y' and the third number be 'z'

The equations according to the question becomes:

⇒ x + y + z = 3              ....(1)

⇒ x - y + z = -3              ....(2)

⇒ x - z = 1 + y              ....(3)

Rearranging equation 3:

⇒ x - y = 1 + z                .....(4)

Putting in equation 2:

⇒ 1 + z + z = -3

⇒ 1 + 2z = -3

⇒ z = -2

Putting this value in equation 4 and equation 1, we get:

⇒ x - y = -1

⇒ x + y = 5

Cancelling 'y' by eliminiation method and equation becomes:

⇒ 2x = 4

⇒ x = 2

Putting value of 'x' and 'z' in equation 1:

⇒ 2 + y - 2 = 3

⇒ y = 3

Hence, the first number is 2, the second number is 3 and the third number is -2

If x = 15 inches, y = 8 inches, z = 11 inches, and h = 6 inches, what is the area of the triangle above?
allsm [11]
Actually to find out the area of the given triangle we don't need to know the measurements of y nor z. Base length x and height h are enough as the formula for triangle's area is 1/2xh.

A = 1/2 * x * h
A = 1/2 * 15 * 6
A = 15 * 3
A = 45

Answer: Area of the given triangle is <u>45 square inches</u> (answer B).
