Answer:

See explanation

Step-by-step explanation:

1. Given the expression

$\dfrac{\sqrt[7]{x^5} }{\sqrt[4]{x^2} }$

Note that

$\sqrt[7]{x^5}=x^{\frac{5}{7}} \\ \\\sqrt[4]{x^2}=x^{\frac{2}{4}}=x^{\frac{1}{2}}$

When dividing $\sqrt[7]{x^5}$ by $\sqrt[4]{x^2},$ we have to subtract powers (we cannot subtract 4 from 7, because then we get another expression), so

$\dfrac{5}{7}-\dfrac{2}{4}=\dfrac{5}{7}-\dfrac{1}{2}=\dfrac{5\cdot 2-1\cdot 7}{14}=\dfrac{3}{14}$

and the result is $x^{\frac{3}{14}}=\sqrt[14]{x^3}$

2. Given equation $3\sqrt[4]{(x-2)^3} -4=20$

Add 4:

$3\sqrt[4]{(x-2)^3} -4+4=20+4\\ \\3\sqrt[4]{(x-2)^3}=24$

Divide by 3:

$\sqrt[4]{(x-2)^3} =8$

Rewrite the equation as:

$(x-2)^{\frac{3}{4}}=8\\ \\(x-2)^{\frac{3}{4}}=2^3$

Hence,

$\left((x-2)^{\frac{3}{4}}\right)^{\frac{4}{3}}=(2^3)^{\frac{4}{3}}\\ \\x-2=2^{3\cdot \frac{4}{3}}\\ \\x-2=2^4\\ \\x-2=16\\ \\x-2+2=16+2\\ \\x=18$

Answer question please

otez555 [7]

Answer:

X=30, Scalene

Step-by-step explanation:

A circle is 360, The triangle is in the circle.

Part A:3x+30+2x+20+5x+10=360

10x+60=360

-60=-60

10x=300

x=30

Part B:Side BA is 3(30)+30=120

Side BC is 2(30)+30=90

Side AC is 5(30)+10=160

All three sides are unequal

What is the area of the semi circle?

Yuki888 [10]

Answer:6.28 ft^2

Step-by-step explanation:

Diameter=4

Radius=diameter ➗ 2

Radius=4 ➗ 2

Radius=2

Area of semicircle=0.5xπx(radius)x(radius)

Area of semicircle=0.5x3.14x2x2

Area of semicircle=6.28 ft^2

Usimov [2.4K]

Answer:

340 people in total

Step-by-step explanation:

If 45% of the people were children, then 100% - 45% = 55% of the people were adults

Equation : 55% of the people were adults

=> .55 * x = 187, x = the total amount of people

=>187/.55x

=> x = 340

340 people in total
