The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
Your mistake is that 1 pound and 15 ounces <em>does not equal</em> 1.15 pounds. You also did not make everything into the same measurement (you mixed up pounds and ounces). I will make everything into the measurement of <em>ounces</em>, since the numbers do not come out clean if we do pounds.
18 pounds (original) = 288
1 pound 15 ounces = 31 ounces
3 1/8 pound = 50 ounces
4 1/2 pound = 72 ounces
So after cutting out those steaks, Mr. Rand has 288-31-50-72 = 135 ounces. Then, it states that he divides those up into 9 ounce patties:
135/9 = 15 patties
And sells them at 3 for $3.12. There are 5 3's in 15 patties, so it is 5 * $3.12 = Mr Rand receives $15.60 for the patties.
That would be 16.625 pounds and/or 266 pounds
Answer:
21.5cm
Step-by-step explanation:
41,572=4/3*pi*r^3
Work backwards to solve for r
The formula for exponential form is:
e^x = y
Where, y in this case is 1800, e is exponential, and we
are to find e^x.
e^x = 1800
To find for x, we have to multiply both sides with the
natural log, ln.
ln (e^x) = ln (1800)
x ln e = ln (1800)
<span>ln e = 1 and by using
the calculator,</span>
x = 7.496 = 7.5
<span>Therefore the exponential form of 1800 is e^7.5</span>
<span>ANSWER: </span>
