A baseball diamond is a square with side 90 ft. A batter hits the ball and runs toward first base with a speed of 31 ft/s. (a) A

Afina-wow [57]

Answer:

13.86 ft/sec

Step-by-step explanation:

If we let x = distance batter has run at time t and D = distance from second base to the batter at time t, then we know $\frac{dx}{dt}=31 ft/s$ and we want $\frac{dD}{dt}$ when he is halfway (at x = 45).

Using Pythagoras theorem

$D^2=90^2+(90-x)^2\\\text{Differentiating with respect to t}\\2D\frac{dD}{dt}=0+2(90-x)(-1)\frac{dx}{dt}\\2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}$

When x=45

$D^2=90^2+(90-x)^2\\D^2=90^2+(90-45)^2\\D^2=10125\\D=\sqrt{10125}$

$2D\frac{dD}{dt}=-2(90-x)\frac{dx}{dt}\\2\sqrt{10125}\frac{dD}{dt}=-2(90-45)(31)\\\frac{dD}{dt}=\frac{-2(45)(31)}{2\sqrt{10125}} =-13.86ft/s$

Thus, when the batter is halfway to first base, the distance between second base and the batter is decreasing at the rate of about 13.86 ft/sec.

The pinata weighs 11/4 pounds without candy.He adds 8bags that weighs 3/8,3/8,1/2,1/2,1/2,3/4,3,11/4 how much will the pinata we

Natalka [10]

Answer:

$Weight = \frac{23}{2}$

Step-by-step explanation:

Given

Weight of Pinata = 11/4 lb

Weight of candies = 3/8, 3/8, 1/2 , 1/2, 1/2, 3/4, 3, 11/4

Required

Weight of Pinata when filled with candies

To solve this question, we simply need to add all weights together

First, we need to add up the weight of the candies

$Candies = \frac{3}{8} + \frac{3}{8} + \frac{1}{2}+ \frac{1}{2}+ \frac{1}{2}+ \frac{3}{4} + 3 + \frac{11}{4}$

Take LCM

$Candies = \frac{3 + 3 + 4 +4 + 4 + 6 + 24 + 22}{8}$

$Candies = \frac{70}{8}$

Simplify:

$Candies = \frac{35}{4}$

Next; Add the weight of the candies to the weight of pinata

$Weight = Candies + Pinata$

$Weight = \frac{35}{4} + \frac{11}{4}$

Take LCM

$Weight = \frac{35 + 11}{4}$

$Weight = \frac{46}{4}$

Simplify

$Weight = \frac{23}{2}$

<em>Hence, the weight of the Pinata after it is filled with candies is 23/2 lb</em>

Which unit is not a measurement of volume? cm L ml cm3

Dahasolnce [82]

Volume is 3 dimentional

cm is 1 dimentional: legnth
L=liters=volume=cubic meter
ml=mililiter=volume=cubic centimeter
cm^3=mililiter

cm is the answer

weight is the measurement of the amount of gravity of an object, it changes depending on where you are (on moon, something has less weight than on earth)
mass is how much matter is in something, doesn't matter where you are (on moon, still same mass as on earth)
