Converting 52ft2 into m2

Slade draws triangle PQR. He then constructs a perpendicular bisector from vertex P that intersects side QR at point T. What can

AVprozaik [17]

Answer:

QT = RT

Step-by-step explanation:

When drawing triangle PQR the perpendicular bisector cuts the triangle in half, which results in two sides that are congruent. This makes QT and RT congruent.

Dan had 2 1/2 cookies and ate 1/2 of a cookie. Of the original number of cookies, the fractional part that he ate was

Lemur [1.5K]

Answer:

1/2 is the fractional part of cookie which was eaten by Dan.

Step-by-step explanation:

Dan has 2 1/2 cookies and ate 1/2, so we can just subtract the 2 1/2-1/2

which cancels out the 1/2, which is the fractional part.

He has 2 cookies left.

Find the dimensions of a closed right circular cylindrical can of smallest surface area whose volume is 128pi cm^3

Ratling [72]

The surface area of a cylindrical can is equal to the sum of the area of two circles and the body of the cylinder: 2πr2 + 2πrh. volume is equal to πr2h.

V = πr2h = 128 pi
r2h = 128
h = 128/r2

A = 2πr2 + 2πrh
A = 2πr2 + 2πr*(128/r2)
A = 2πr2 + 256 π / r

the optimum dimensions is determined by taking the first derivative and equating to zero.

dA = 4 πr - 256 π /r2 = 0
r = 4 cm
h = 8 cm
