Answer:

A = 14.8 B = 14.8

Step-by-step explanation

What you do first is you use the pythagorean theorem to write out the equation

a^2 + b^2 = c^2

a^2 + b^2 = 21^2

a^2 + b^2 = 441

i couldnt find any whole numbers to fit in this equation so just divide 441 by 2

and get the square root of 220.5 which is 14.8 to the nearest tenth for both a and c

Rewrite each expression so that each term is in the form kxn, where k is a real number, x is a positive real number,

MaRussiya [10]

Answer:

So the equation in standard form will be $x^{\frac{-1}{3}}$

Step-by-step explanation:

We have given equation $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}$

We have to write this expression in standard form

For writing in standard form first we have to do operation on the expression

We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added

So $x^{\frac{-2}{3}}\times x^{\frac{1}{3}}=x^{\frac{-2}{3}+\frac{1}{3}}=x^{\frac{-1}{3}}$

So the equation in standard form will be $x^{\frac{-1}{3}}$

. If three angle of a quadrilateral are in the ratio 2: 3: 5 and fourth angle is 130

alexgriva [62]

Answer:

Step-by-step explanation:

So let the angles be 2x,3x,5x

∠A + ∠B + ∠C + ∠C = 360

[Sum of all the angles of a quadrilateral ]

⇒2x+3x+5x+130=360

⇒10x = 360 -130

⇒x = 23

The angles are ,

∠A = 2x = 2×23 = 46

∠B = 3x = 3×23 = 69

∠C = 5x = 5×23=115

The Buffalo bills are offering autographs signings they charge a supply fee of 8.00 and a player fee of 13.25 per autograph you

Anika [276]

Total to pay per autograph= 8.00+13.25=21.25

Number of autographs you can buy = 2(21.25)= 42.5
You can buy two autographs and have a change of 8.25
