A board of length 16 ¾ inches is cut into 4 equal pieces. If 7/8 of an inch is then removed from one of these pieces, what is th

spayn [35]

Answer: $\dfrac{53}{16}\ \text{or}\ 3\dfrac{5}{16}$

Step-by-step explanation:

Given

Length of board is $16\ \frac{3}{4}$

It is divided into 4 equal pieces i.e. length of each piece is

$\Rightarrow \dfrac{\frac{64+3}{4}}{4}=\dfrac{67}{16}\ \text{in.}$

If $\frac{7}{8}$ of an inch is removed from one of the pieces then,

$\Rightarrow \dfrac{67}{16}-\dfrac{7}{8}\\\\\Rightarrow \dfrac{67}{16}-\dfrac{14}{16}=\dfrac{53}{16}\ \text{inch}$

What is the volume of a cone with a diameter of 30 feet and a hight of 60 feet

ivolga24 [154]

Answer:

4500 $\pi$ $ft^{3}$ or 4712.39 $ft^{3}$

What we need to know: The formula for the volume of a cone is: $V=\pi r^{2} \frac{h}{3}$

So we are solving for V

Step-by-step explanation:

1) Radius is half of diameter r=30/2 thus, your radius is 15

2) you then have all your variables so you can start plugging values into your equation:

r=15 h=60

$V=\pi 15^{2} \frac{60}{3} \\V=\pi (225)*(20)\\V=\pi(4500) \\V= 4500\pi$

This would be your exact answer but if you are solving for a rounded answer it would be

V~4712.39 $ft^{3}$

Answer: Choice B) The graph opens down

The negative 'a' value means the parabola opens downward. One way to remember it is that the positive 'a' value means "happy face" or "smile", and a negative 'a' value means "frowny face".

See the image attachment and note the color coding of the graphs.
