It is given here that the cost of a pair of jeans is $89. It is also given in the problem that a jeans jacket costs twice as much as the pair of jeans.
Now
The cost of the jeans jacket = (2 * 89) dollars
= 178 dollars
Cost of 1 pair of jeans = 89
So
The cost of 4 pairs of jeans = (89 * 4) dollars
= 356 dollars
So we come to know that the cost of a jean jacket is $178 and the cost of 4 pairs of jeans is $356.
Total cost for the jean jacket and 4 pairs of jeans = (178 + 356) dollars
= 534 dollars
So $534 is the total cost of the jean jacket and 4 pair of jeans.

Answer:
<h2>
2.45</h2>
Step-by-step explanation:
Given f(x)=√x+1 and g(x)=3+√x, to calculate for (f∘g)(4), first we need to get the function (f∘g)(x).
(f∘g)(x). = f{g(x)}
since g(x) =3+√x, then;
f{g(x)} = f(3+√x)
If f(x) = √x+1
f(3+√x) can be gotten by simply replacing x with 3+√x in f(x)
f(3+√x) = √(3+√x)+1
f{g(x)} = √(3+√x)+1
f{g(4)} can be gotten by substituting x = 4 into the resulting function above.
f{g(4)} = √(3+√4)+1
f{g(4)} = √(3+2)+1
f{g(4)} = √5+1
f{g(4)} = √6
f{g(4)} = 2.449 ≈ 2.45 to two decimal places.
Hence, (f∘g)(4) for the functions to two decimal places is 2.45
Answer:
A. 862.4 in^2
Step-by-step explanation:
1) (14x8.9)=124.6
124.6x4(4 sides have the same surface area)=498.4
2) 13x7(half of the 14in)=91
3) Typically, to find the surface area of a right triangle, you would divide the answer by 2, but since we have 8 right triangles, we can just multiply the 91 by 4. 91x4=364
4) 364+498.4=862.4 in^2
