By what percent will the fraction change if its numerator is increased by 25% and its denominator is increased by 20%? please an
d1i1m1o1n [39]
<h2>Answer:</h2><h2>The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %</h2>

Step-by-step explanation:

Let the fraction be represented as \frac{x}{y} where x is the numerator and y is the denominator

Given that numerator will increase by 25 %, = 25% x

   = 0.25 x

Given that denominator will increase by 20 %, = 20% y

   = 0.2 y

The new fraction becomes  = \frac{x + 0.25 x}{y + 0.2 y}

= \frac{1.25 x}{1.2 y}

= (\frac{1.25}{1.2} ) \frac{x}{y}

The new fraction will chnage by 1.25 : 1.2 ratio, (i.e) = 1.04 %

List the sides of each triangle from shortest to greatest
Lelechka [254]
In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.


a.70^o\ \textgreater \ 60^o\ \textgreater \ 50^o so |RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|, 

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ


b. The sum of the measures of the interior angles of any triangle is 180°, 

so 

m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o

thus, m(C) is the largest angle. This means the largest side is the side AB.



Answers:

a) RQ
b)AB

The diameter of the wheels on your car is 25 inches. You are going to drive 458 miles today. Each of your wheels is going to tur
Kipish [7]

d = Diameter of wheels = 25 inches

s = Distance to be traveled by the wheels = 458 miles

Converting the miles to inches

s=458\times 5280\times 12=29018880\ \text{inches}

The distance traveled by the wheels in rotation is the circumference

D=\pi d\\\Rightarrow D=\pi\times 25

The number of rotations required to cover the distance would be

\dfrac{s}{D}\\ =\dfrac{29018880}{\pi\times 25}\\ =369479.855599

1 rotation is 360^{\circ} so

369479.855599\times 360=133012748.016^{\circ}

The number of rotations to cover the required distance is 133012748.016^{\circ}
