Makovka662 [10]2 years ago
3 0

Answer:

  • See below

Step-by-step explanation:

  • 1) Total points = 25
  • 2) Points earned = 21
  • 3) Percent score = 84%

<u>Proportion:</u>

  • 21 / 25 = 84% / 100%

Solving the others in the table

<u>21 out of 25 points:</u>

  • 21/25 = x/ 100 ⇒ x = 100*21/25 = 84

<u>15 out of 20 points:</u>

  • 15/20 = x/100 ⇒ x = 100*15/20 = 75

<u>47 out of 50 points:</u>

  • 47/50 = x/100 ⇒ x = 100*47/50 = 94

<u>28 out of 30 points:</u>

  • 20 / 30 = x/100 ⇒ x = 100*20/30 = 66.66

<u>19 out of 45 points:</u>

  • 19/45 = x/100 ⇒ x = 100*19/45 = 42.22

<u>3 out of 4 points:</u>

  • 3/4 = x/100 ⇒ x = 100*3/4 = 75

Simplify the expression. (16y54y3)12 Enter your answer in the box.
sp2606 [1]

Answer:

Simplify the expression: (16y^{\frac{5}{4}}y^3)^{\frac{1}{2}}

Use the exponent power:

  • a^n \cdot a^m = a^{n+m}
  • \sqrt[n]{a^n} =a
  • (a^n)^m = a^{nm}

(16y^{\frac{5}{4}}y^3)^{\frac{1}{2}}

Apply the given rules;

(16y^{\frac{5}{4} +3} )^{\frac{1}{2}}

Simplify:

(16y^{\frac{17}{4}} )^{\frac{1}{2}}

then;

(16)^{\frac{1}{2}} \cdot (y^{\frac{17}{4}})^{\frac{1}{2}} = 4y^{\frac{17}{8}}

Therefore, the simplified expression of (16y^{\frac{5}{4}}y^3)^{\frac{1}{2}} is, 4y^{\frac{17}{8}}
