Area = length * width
A = 60 * 20
A = 120 square feet
Answer:
4) 95*.6=57
5) 60-18=42 42/60=70%
6) 26800-5500=21300 21300*.15=3195$
9)9200*.07=644 644+800=1444
3) 36*.75=27ft
Step-by-step explanation:


taking common


Alright, so here, we can simply divide 0.75/3=0.25 due to that we need to find that we need to find the unit rate of each pound, and we have 3, so we need to divide by 3
A geometric sequence is a sequence in which there is a common ratio between any two consecutive terms. In this case if X:Y:Z are in the ratio of 2:7:8 the multiplying by a constant k, we have X=2k, Y= 7k and Z=8k.
Then if X, Y-12, Z form a Geometric sequence, it means X/Y-12=Y-12/Z which is the same as 2k/7k-12=7k-12/8k if we cross multply, we get
16k²= 49k²-168k +144
33k²-168k+144 =0 solving for k
k = 4 or 1.091 if we take the whole number to find the values of X,Y and z,
X= 8, Y= 28 and Z=32
