Answer:
x=15
Step-by-step explanation:
Answer:
4,257 m²
Step-by-step explanation:
step 1
Find the lateral area of the rectangular prism (ottoman)
The lateral area is
LA=PH
where
P is the perimeter of the base
H is the height of the prism
Find the perimeter of the base P
P=2(37+21)=116 cm
we have H=30 cm
<em>Find the lateral area</em>
LA=116(30)=3,480 m²
step 2
Find the area of the top of the ottoman
B=37*21=777 m²
step 3
we know that
The fabric needed to cover the sides and top of the ottoman is equal to sum the lateral area plus the area of the top
3,480+777=4,257 m²
Let's look at the decimal number. We want to know where root 91 is in relation to the decimal number. The decimal number is between 12 and 13, or in other words, between
and
. Both of these numbers are larger than
meaning that the answer has to be
A
The first term is n=1
so 10th term is n=10
5(10)+100=50+100=150
150 is 10th term
