What is greater 500 in or 40 ft

Answers

What is greater? 500in or 40 ft

First let's set up a proportion:

1 foot = 12 inches

Ok, now that we setup our proportion lets figure out which one is greater
(please note that y is a variable):

five hundred inches:

y feet= 500/12
y feet = 41.6

Therefore 41.6 feet = 500 inches, and 41.6ft is greater than 40 ft
So 500 inches is greater

If y is 9 and x is 12, what additional information is necessary to show that triangle DUM is congruent to triangle MAP using the SAS postulate?

Answers

Δ DUM Δ MAP

hypotenuse: 15 2y-3
short leg: 12 0.5x + 6

y = 9 ⇒ 2(9) - 3 = 18 - 3 = 15 Congruent with the hypotenuse of Δ DUM
x = 12 ⇒ 0.5(12) + 6 = 6 + 6 = 12 Congruent with the short leg of Δ DUM

SAS postulate states that two triangles are congruent if 2 of its sides and 1 angle have equal measure. Both the hypotenuse and short leg are equal in measure. Thus, both triangles are congruent with each other.

The pair of points( 6 ,y) and (10, -1) lie on a line with slope 1/4. What is the value of y?

Answers

We know that general formula for the line is y=ax+b, we know that a=1/2. To get b we can subsittute x=10 and y=-1 (from the second point)
-1=1/2*10+b
-1=5+b /-5
-6=b
We know that our line is y=1/2x-6
Now we can substitute x=6 (from first point) and find value of y
y=1/2*6-6
y=3-6
y=-3 - its the answer
