Answer:
256.5 lbs
Step-by-step explanation:
Add 323 and 190, and divide by 2.
9.75%=9.75 / 100
=0.0975
=0.0975 / 1 × 10000 / 10000
=975 / 10000
=39 / 400
Hope this helps :)
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 cm
width 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 cm
Height of the triangle ,H = 8 cm
Surface 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 cm²
Therefore, Option D is correct.
First you divide 380 by 100 to get what 1% is, (3.8) and then you multiply by 18 to give you 18%. The answer is 68.4, so add that to 380 and you'll have the final answer of 448.4.
