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. Step-by-step explanation:
You have to ask yourself how would you read that decimal? It is 162 ten-thousandths because the last digit, which is 2 is in the ten-thousandths place. So the fraction would be 162/10000
Answer:
Step-by-step explanation:
Where are the other graphs?
A=P(1+r/n)^(tn)
n=number of times per year compounded
A=amount
P=principal inveseted
r=rate in decimal
t=time in years
so
we want A=30000
r=12.4%=0.124
t=15
monthyl means n=12
30000=P(1+0.124/12)^(15*12)
solve for P
easy, just divide both sides by (1.01033)^180
4714.97=P
that much must be invested
