A fraction consists of two numbers and a fraction bar:

30/50

The number above the bar is the numerator: 30

The number below the bar is the denominator: 50

Divide the numerator by the denominator to get fraction's value:

Find The length of one leg of a right triangle if the length of the hypotenuse is 18 feet and the length of the other leg is 14

Brums [2.3K]

Answer:

a = 8√2

Step-by-step explanation:

a² + b² = c²

a² +14² = 18²

a² + 196 = 324

Subtract 196 from both side

a² = 128

Take the square root of both sides

a = √128

a = √(64 * 2)

a = 8√2

If two lines are perpendicular, which statement must be true? A) The product of their slopes is 1. B) Their slopes are opposites

castortr0y [4]

If two lines are perpendicular, the statement that must be true is : D. The product of their slopes is -1

Lets say that a line has a slope of 2, the line which perpendicular to that line would have a slope of -1/2

Which means, the product would be 2(-1/2) = -1

Select proportional or not proportional to correctly classify the pair of ratios. 1.2/3 and 1.8/4.5

Gnesinka [82]

Answer:

Proportional.

Step-by-step explanation:

Find the cross products. If they are same, then they are proportional.

$\dfrac{1.2}{3} = \dfrac{1.8}{4.5}$

Cross multiply,

1.2 * 4 .5 = 3*1.8

5.40 = 5.4

So, they are proportional.

Multiply the numerator and denominator of 1.2/3 by 1.5

$\dfrac{1.2*1.5}{3*1.5}=\dfrac{1.8}{4.5}$

From this we come to know they are proportional

1.2 : 3 :: 1.8 : 4.5

Product of means = 3*1.8 = 5.4

Product of extremes = 1.2*4.5 = 5.4

Product of means = product of extremes. So, they are proportional.
