I think the equation is still the same as a non-right triangle. a=(w*l)/2
As long as it's a triangle, that would be the equation. This is because for finding the area for a square or rectangle (quadrilateral) is always a=w*l, that means that the equation for any triangle is always a=(w*l)/2. The division by 2 for the triangle's equation is there because a triangle is half of a quadrilateral. So you would have to divide the quadrilateral's equation by two. Hope I helped :)
Answer:
y = -2x + 16.
Step-by-step explanation:
We are given the slope and a point on the line, so
we use the point-slope form of a straight line:
y - y1 = m(x - x1)
Here gradient m = -2, x1 = 4 and y1 = 8 , so we have:
y - 8 = -2(x - 4)
y - 8 = -2x + 8
y = -2x + 16.
Which statement regarding the graph is true? Which of the following statements is true?
Question:
The store sold 4,000 fewer units in November than in August.
Answer:
FALSE.
Explanation:
Number of units sold in November = 3000
Number of units sold in August = 6000
difference in both = 6000-3000= 3000
which not same as 4000 hence wrong
Question:
More customers prefer chocolate than strawberry and vanilla combined.
Answer:
FALSE.
Explanation:
value for Chocolate is 38% which is clearly less than combined value of strawberry (30%) and vanilla (22%). which is (30+22=52%)
Question:
Yogurt sales had a decreasing trend during the last four months of 2011.
Answer:
TRUE
Explanation:
Graph is going down ward for the last four months (sept to Dec) which means decreasing sales.
Question:
The median number of ounces sold from 3 to 4 p.m. was more than the median number sold from 7 to 8 p.m
Answer:
FALSE.
Explanation:
It is not true for all Stem values.
Like when stem =1, then (3 to 4 p.m.) has median =0
but for (7 to 8 p.m) has median 6 which is more than 3 to 4 pm
Answer:
1. The rectangular prism is a right prism with rectangular bases (check the picture)
2. It has 8 vertices, so we are looking for 3d figures with 4 vertices.
3. A face can have at least 3 vertices, and the 4th must be outside of the plane determined by the first 3 vertices. This makes 4 vertices in total.
4. The 3d figure described in step 3 is a pyramid.
so the answer is prism
