The formula is b times h / 2
So 19/12 x 13/7 / 2

Answer from: debramknoxx

Hello!

To calculate the area of the triangle, you use the formula A=0.5bh. We will plug this into the numbers to get our answer.
19/12·13/7=247/84. We can get half of this by multiplying the denominator by two. Now we have 247/168. To get this in decimal form, we just divide 247 by 168. To the nearest hundredth it is about 1.47 in².

Lets check our answer by converting the original numbers to decimals and see if we get the same answer.
1.58·1.86=2.94/2=1.47, which matches our answer above.

The answer is 1.47 in².

I hope this helps!

Answer: choice c and choice d

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer
