Your answer would be 31.5 (so 32 when rounded up)

For triangles you basically multiply them together, and the divide your answer by two. 

A= 1/2 b x h 
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)

I hope I helped and if you need more you could always ask me :)

Given that this is a right triangle the formula would then be A =ab/2
Using that formula 
Your answer is 31.5
Your equation would look like this A= 7(9)/2

Answer:

1. 23/20 miles, 2. 7/20 miles

Step-by-step explanation:

1. Total distance = 3/4 + 2/5

= (3*5)/(4*5) + (2*4)/(5*4)

= 15/20 + 8/20

= 23/20

= 1 3/20 miles

2. Difference between walked miles and jogged miles = 3/4 - 2/5

= 15/20 - 8/20

= 7/20 miles

What are the coordinates of the circumcenter of this triangle?
Oduvanchick [21]

Answer:

The coordinates of the circumcenter of this triangle are (3,2)

Step-by-step explanation:

we know that

The circumcenter is the point where the perpendicular bisectors of a triangle intersect

we have the coordinates

A(-2,5),B(-2,-1),C(8,-1)

step 1

Find the midpoint AB

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2-2}{2},\frac{5-1}{2})

M_A_B=(-2,2)

step 2

Find the equation of the line perpendicular to the segment AB that passes through the point (-2,2)

Is a horizontal line (parallel to the x-axis)

y=2 -----> equation A

step 3

Find the midpoint BC

The formula to calculate the midpoint between two points is equal to

M=(\frac{x1+x2}{2},\frac{y1+y2}{2})

substitute the values

M=(\frac{-2+8}{2},\frac{-1-1}{2})

M_B_C=(3,-1)

step 4

Find the equation of the line perpendicular to the segment BC that passes through the point (3,-1)

Is a vertical line (parallel to the y-axis)

x=3 -----> equation B

step 5

Find the circumcenter

The circumcenter is the intersection point between the equation A and equation B

y=2 -----> equation A

x=3 -----> equation B

The intersection point is (3,2)

therefore

The coordinates of the circumcenter of this triangle are (3,2)
