Answer:

It's 31.5

Step-by-step explanation: The formula for right triangle is A=ab/2. A=area, a is one of the legs and b is the other leg. So you had for one leg 9 and for the other 7. You multiple 9 x 7 = 63. 63/2 = 31.5 for the area

What is the equation of the graphed linear model?<br><br><br><br> y = <br> x +
timofeeve [1]

Answer:

y = - 2x + 110

Step-by-step explanation:

The equation of a line in slope- intercept form is

y + mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 110) and (x₂, y₂ ) = (20, 70) ← 2 points on the line

m = \frac{70-110}{20-0} = \frac{-40}{20} = - 2

the line crosses the y- axis at (0, 110) ⇒ c = 110

y = - 2x + 110 ← equation of line

Eduardo used fabric to make three costumes. he used 1/4 yard for first then 2/4 yard for the second and 3/4 yard for the third c
Dmitry [639]
 add the fractiosn together, since they all have the same denominator, simply add the numerators
1/4+2/4+3/4=6/4
or
1 1/2 yards of fabric (2/4 = 1/2)

The equation of a circle is ​ (x−11)2+(y+15)2=144 ​ .<br><br> What is the circle's radius?
yuradex [85]
The equation of a circle is (x-h)^2+(y-k)^2=r^2, where (h,k) is the center and r is the radius.
To find the radius, we would find the square root of 144, which is 12.
r=12
