Answer:
2070 / 6930 = 0.2987.....x 100 = 29.87%
1) 8y=-5x+12
y=-5/8x+3/2
2)2y=3x+7
y=3/2x+7/2
3)-3y=-2x+7
y=2/3-7/3x
4)-4y=16-12x
y=3x-4
5)-2y=-x+10
y=2x-5
To solve the problem you must apply the corresponding formulas for calculate the area of each figure. Therefore, you have:
1-A cube where the length of each edge is 4 inches: <span>96 square inches
</span><span> A=6a^2=96 inches^2
2- A triangular prism where the area of each base is about 20 square inches, the length of each side of the base is 6 inches, and the height of the prism is 2 inches: </span><span>76 square inches.</span><span>
3- A square pyramid with a base length and slant height of 5 inches: 75</span><span> square inches.
</span><span>A=2(5)(5)+5^2=75 inches^2
4- A rectangular prism with a length of 5 inches, a width of 4 inches, and a height of 3 inches:</span>94 square inches .
A=2(4x5+3x5+3x4)=94 inches^2
