Answer:

second option : the side length was multiplied by 5.

Step-by-step explanation:

a = side length of the original square

A² = a×a

(a+5)×(a+5) = a² + 10a + 25

and that should be equal to a²×25

a² + 10a + 25 = 25a² ?

10a + 25 = 24a²

no, that is not true for all a

a×5 × a×5 = a²×25 = 25A²

this is the correct solution, as it is true for all a.

Answer:

A=bh=24*8=192

V=2(wl+hl+hw)=2·(4·3+15·3+15·4)=234

A=1311(big rectangle ---> (31-12)69)+2(12 x 23 ---> because of the two smaller rectangles=1311+552=1863

What is the best estimate of a 20% tip on a $48 haircut?
Ksju [112]
To find an estimate, the bets ting to do is to round $48 up to $50. As you've got to find 20%, just divide $50 by 5 $50/5= $10 An estimate for a 20% tip of $48 is $10 Hope this helps :)

One particular 13-foot tall cone of dry sand has a base diameter of 38.6 feet. To the nearest tenth of a degree, what is the ang
Nataly_w [17]
34.0 degrees, 29.6 feet in Diameter.
This is a right triangle trigonometry question.
Use half of the diameter to form the base of the triangle (19.3 ft) with a height 0f 13.
Use Inverse Tangent function to find the angle of repose
tan ^{-1}(\frac{Opposite}{Adjacent} ) = Angle of repose

tan ^{-1}(\frac{13}{19.3} ) = 33.96 round to 34.0

then use the angle of repose to solve trigonometric function of the tangent for the radius of the other cone.

tan(Angle)= \frac{opp}{adj}

tan(34)=(\frac{10}{x} )

switch denominator and tangent

x=(\frac{10}{tan(34)} ) =14.82
multiply by 2 to get diameter of second cone
14.82*2≈29.6
