Answer:
74.97+n
Step-by-step explanation:
We need to simplify the given polynomial i.e.
27.97 + 47+ n
Here, n is a constant number
Firstly we add 27.97 and 47 such that,
27.97 + 47+ n = 74.97+n
Hence, the simplified form is 74.97+n.
Answer:
The cost of maintenance and repairs is $235
Step-by-step explanation:
step 1
Find the market values of car for age of car equal to 7 year
Observing the graph
The percentage of market value is 10%
so
10%=10/100=0.10
The market value is equal to
$23,500*0.10=$2,350
step 2
Find the cost of maintenance and repairs for age of car equal to 7 year
Observing the graph
The percentage of maintenance and repairs of car's value is 10%
so
10%=10/100=0.10
The cost of maintenance and repairs is
$2,350*0.10=$235
Answer:
<h2>R = 16 in</h2>
Step-by-step explanation:
The formula of a Surface Area of a sphere:
![S.A.=4\pi R^2](https://tex.z-dn.net/?f=S.A.%3D4%5Cpi%20R%5E2)
R - radius
We have
![S.A.=1024\pi\ in^2](https://tex.z-dn.net/?f=S.A.%3D1024%5Cpi%5C%20in%5E2)
Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>
![R^2=256\to R=\sqrt{256}\\\\R=16\ in](https://tex.z-dn.net/?f=R%5E2%3D256%5Cto%20R%3D%5Csqrt%7B256%7D%5C%5C%5C%5CR%3D16%5C%20in)
