The multiplying division subtract addition
The answer is false
because the area of a triangle is 1/2 b*h
so in this case, it would be 1/2 15 * 8
and 15 * 8 = 120 and 120 divided by 2 = 60 not 40
Answer:
2
Step-by-step explanation:
First off, the slope of f(x) is -4. It is in the form y=mx+b and m=-4.
For g(x), the slope can be calculated from any two points given. I willuse (1,9) and (3,21) because I like positive numbers. So, slope is rise over run and it is calculated from (y1-y0)/(x1-x0) This gives me (21-9)/(3-1) which is equal to 6. So adding the two slopes: 6+ (-4)=2
Answer:
408 sq. in.
Step-by-step explanation:
The total surface area of the pyramid is the sum of all 4 faces (each of them a triangle) and square base.
Triangle area is where b is base and h is height.
base of triangle is 12 and height is 11
So area of each triangle is
There are 4 of them, so total is 66 * 4 = 264
Now, square has an area of where s is the side length.
It is given s = 12, so the area of the square base is:
Total Surface Area of the Pyramid is 264 + 144 = 408 sq. in.
Answer:
4 over 5
Step-by-step explanation:
36 divided by 9 is 4 and 45 divided by 9 is 5. so the answer is 4/5
