A triangle has three different integer side lengths and a perimeter of 20 units. What is the max length of any one side?

1 answer:

3 0

X + x+1 + x + 2 = 20
3x + 3 = 20
3x = 17 but can't start with x = 6 because 6+7+8 > 20,
so have start with 5 + 6 + 7 = 18 are the 3 sides.

Answer:

$163

Step-by-step explanation:

182 - 19 = 163

Bob has $163 left.

What expression is equivalent to [x1/4*y16]^1/2

tigry1 [53]

Answer:

The given expression is ${{{\bf x}^{\frac{\bf 1}{\bf 4}}\times y^{\bf 16}}} ^ {\frac{1}{2}} =x^{\frac {\bf 1}{\bf 8}}\times y^{\bf 4}$ .

Step-by-step explanation:

The given expression is ${{x^{\frac{1}{4}}\times y^{16}}}^\frac{1}{2}$

${{x^{\frac{1}{4}}\times y^{16}}}^{\frac{1}{2}}=\sqrt{x^{\frac{1}{4}}\times y^{16}}$

${{x^{\frac{1}{4}}\times y^{16}}}^{\frac{1}{2}}= \sqrt{x^{\frac{1}{4}}}\times \sqrt{y^{16}}$

${{x^{\frac{1}{4}}\times y^{16}}}^{\frac{1}{2}}=x^{\frac{1}{4}}^\frac{1}{2}} \times y^{4}$

${{x^{\frac{1}{4}}\times y^{16}}}^{\frac{1}{2}}= x^{\frac{1}{8}}\times y^{4}$ by using ${a^{m}} ^{n}=a^ {mn}$ property.

Formula: total = principal x (1 + (interest rate x loan time))

total = 1000 x (1 + (0.055 x 2))

total = 1000 x (1 + 0.11)

total = 1000 x 1.11

total = $1110
