Answer:

A. hexagonal prism

Step-by-step explanation:

The top and bottom must be 2 congruent hexagons, the hexagon has 6 sided figure, so there must be 6 congruent rectangle faces.

Therefore, the answer is A. Hexagonal prism.

Hope this will helpful.

Thank you.

The area of the shaded segment is 100cm^2. Calculate the value of r.
Reil [10]
Hello, 

The formula for finding the area of a circular region is: A=  \frac{ \alpha *r^{2} }{2}

then:
A_{1} = \frac{80*r^{2} }{2}

With the two radius it is formed an isosceles triangle, so, we must obtain its area, but first we obtain the height and the base.

cos(40)= \frac{h}{r}  \\  \\ h= r*cos(40)\\ \\ \\ sen(40)= \frac{b}{r} \\ \\ b=r*sen(40)

Now we can find its area:
A_{2}=2* \frac{b*h}{2}  \\  \\ A_{2}= [r*sen(40)][r*cos(40)]\\  \\A_{2}= r^{2}*sen(40)*cos(40)

The subtraction of the two areas is 100cm^2, then:

A_{1}-A_{2}=100cm^{2} \\ (40*r^{2})-(r^{2}*sen(40)*cos(40) )=100cm^{2} \\ 39.51r^{2}=100cm^{2} \\ r^{2}=2.53cm^{2} \\ r=1.59cm

Answer: r= 1.59cm

The average cost when producing x items is found by dividing the cost function, C(x), by the number of items, x. When is the ave
kakasveta [241]

Answer:

<em>The average cost is less than 100 when the number of items x is greater than 2</em>

Step-by-step explanation:

The cost equation is C(x) = 10x + 180

The average cost Cp = \frac{C(x)}{x}

We want to know when the cost Cp is less than 100.

So

Cp

Cp = \frac{C(x)}{x}

10 + \frac{180}{x}

For x> 0

\frac{180}{90}

x> 2

The average cost is less than 100 when x>2

In a basketball game, Tatiana made 23 baskets. Each of the baskets was worth either 2 or 3 points, and Tatiana scored a total of
vekshin1

X+y=23 (x and y added equal the number of baskets made)

2x+3y=53 (since each basket is worth a certain amount of points, x and y must be multiplied by their amount of baskets and added together to get the total number of points)

Hope this helps!
