Step-by-step explanation:
Steps to solve "7500 is 35 percent of what number?" We have, 35% × x = 7500 or, 35 100 × x = 7500 Multiplying both sides by 100 and dividing both sides by 35, we have x = 7500 × 100 35 x = 21428.57 If you are using a calculator, simply enter 7500×100÷35, which will give you the answer.
Answer:
Answer:Option D is correct.Step-by-step explanation:We are given with a solid figure with cuboid in base and square based pyramid in top.we have to find Surface of the figure.Surface Area = Curved surface ares of cuboid + area of base of cuboid + lateral surface area of pyramid.Length of the cuboid, l = 8 cmwidth of the cuboid , w = 8 cm height of the cuboid , h = 11 cm Lateral surface area of pyramid = 4 × Area of a triangle Base of triangle , b = length of cuboid = 8 cmHeight of the triangle ,H = 8 cmSurface Area = 2 × h × ( l+w ) + l × b + 4 × 1/2 × b × H = 2 × 11 × ( 8 + 8 ) + 8 × 8 + 2 × 8 × 8 = 22 × 16 + 64 + 128 = 352 + 192 = 544 cm²Therefore, Option D is correct.
