last question i also dont know
Step-by-step explanation:
the area of a triangle is
baseline × height / 2
we have here 2 triangles : the larger, outer shaded one, and the smaller, inner white one.
to get the area of the shaded part, we need to calculate the area of the large triangle and subtract the area of the smaller triangle.
large area :
12 × 15 / 2 = 6 × 15 = 90 ft²
small area :
8 × 10 / 2 = 4 × 10 = 40 ft²
the shaded area is
90 - 40 = 50 ft²
I’m not sure, you’re not elaborating enough to this equation. Are you sure you’re not missing a phrase of some sort?
10 and -7 times each other equals -70.
10 plus -7 equals 3.
Hope this helps you! (:
To determine how many different types of shelves could be ordered, you will multiply all the numbers from each different aspect of the shelves to create all the possible combinations that could occur.
The reason for doing this has to do with the groupings that will occur using all three numbers.
4 x 3 x 6 = 72
There are 72 different possibilities of shelves.
