1 answer:

8 0

Hello! There is a markup, so the price goes up. We add 1 to the percentage rate in decimal form, then we multiply that by the original price to go straight to the new price. 45% in decimal form is 0.45. 1 + 0.45 is 1.45. 25 * 1.45 is 36.25. There. The new price of the jeans is $36.25.

Answer:

$\boxed{\sf sin\ C =\frac{40}{41}}$

Step-by-step explanation:

We need to find out the value of sinC using the given triangle . Here we can see that the sides of the triangle are 40 , 41 and 9 .

We know that the ratio of sine is perpendicular to hypontenuse .

$\sf\longrightarrow sin\theta =\dfrac{ perpendicular}{hypontenuse}$

Here we can see that the side opposite to angle C is 40 , therefore the perpendicular of the triangle is 40. And the side opposite to 90° angle is 41 . So it's the hypontenuse . On using the ratio of sine ,

$\sf\longrightarrow sinC =\dfrac{ p}{h}\\\\\sf\longrightarrow sin\ C =\dfrac{AB}{AC}$

Substitute the respective values ,

$\sf\longrightarrow \boxed{\blue{\sf sin\ C =\dfrac{40}{41}}}$

<u>Hence the required answer is 40/41.</u>

Hello,
A=(2.21082279...,3.996803798)
$\left \{ {{h=-0.2d^2+2.25d} \atop {h=d/6+21.77/6}} \right. \\\\

\Rightarrow\ 1.2d^2-12.5d+21.77=0\\\\

\Rightarrow\ d=2.21082279..\ or\ d=8.20584..\\\\
