Answer:

#11

<u>Complementary angles ad to 90°</u>

  • b = 90° - 65° = 25°

#12

<u>Alternate exterior angles are congruent</u>

  • b = 60°

#13

<u>Complete angle and angle addition postulate</u>

  • b = 360° - (244° + 23°) = 93°

#14

<u>Vertical angles are congruent</u>

  • b = 46°

#15

<u>Complementary angles add to 90°. Straight angle is 180°</u>

  • b = (180° - 90°) - 39° = 51°

#16

<u>Alternate interior angles are congruent</u>

  • b = 85°

Simplify expression with rational exponents.
musickatia [10]
27^(4/3)+4^(3/2) can be simplified using roots.  

The cube root of 27 is 3 and the square root of 4 is 2.  This removes the denominators from the expression.  The expression is now 3^4+2^3.

Simplify this and you get 81+8=89

<h3><u>Answer</u> :</h3>

\bigstar\:\boxed{\bf{\purple{x^{\frac{m}{n}}}=\orange{(\sqrt[n]{x})^m}}}

Let's solve !

:\implies\sf\:25^{\frac{3}{2}}

:\implies\sf\:(\sqrt[2]{25})^3

:\implies\sf\:5^3

:\implies\boxed{\bf{\red{125}}}

<u>Hence, Oprion-D is correct</u> !

Calculate the annual return percentage
xenn [34]
The annual return percentages will be evaluated using the formula:
A=P(1+r/100)^n
where:
A=amount
P=principle
r=rate
n=time

a] A=$500, P=$400, n=1 years
500=400(1+r)^1
solving for r we shall obtain:
1.25=1+r
hence
r=1.25-1
r==0.25
annual rate of investment is 25%

b] A=2500+100=$2600, P=$ 2000, n=1 year
hence
2600=2000(1+r)^1
2600/2000=1+r
1.3=1+r
r=1.3-1
r=0.3 
annual rate of investment is 30%
