Answer:
55%
Step-by-step explanation:
Since the perimeter of the square is 40, its side length is 40/4 = 10, so its area is 100.
To find the percentage of the shaded area, I am going to find the unshaded areas, which consist of 2 triangles.
The one on the left has lengths of 10(side length of the square) and 3(10-7), which means it has an area of 10*3/2 = 15.
The one on the right has lengths of 10(side length of the square) and 6(10-4), which means it has an area of 10*6/2 = 30.
That means the unshaded area is 15+30 = 45.
To find the shaded area, just subtract 45(unshaded area) from 100(area of square), which is 55 cm^2.
55 cm^2 is exactly 55% of 100, so the answer is 55%.
I hope this helped you.
Answer:
y=-3x-13
Step-by-step explanation:
Plug in the -2 and -4 for the y and x. The slope is the same
1) -4 = -3 (-3)+b
2) -4=9+b
3) -4-9=b
4) -13=b
The equation is y=-3x-13
We have been given that Liam makes soap sculptures of sea turtles each sculpture weighs 3/8 pounds. He ships them in a wooden box that weighs 2 pounds. The total weight of the box filled with the sea turtles is 5 pounds.
We are asked to find the number of sea turtles in the box.
First of all, we will subtract the weight of the box from total weight to find the weight of all sea turtles.
Now we will divide total weight of all turtles by weight of one turtle to find number of turtles.
Therefore, there are 8 sea turtles in the box.
