Vcone=(1/3)hpir^2
h=11
r=2.5
Vcone=(1/3)11pi2.5^2
Vcone=(11/3)pi6.25
Vcone=68.75/3*3.14
Vcone=71.95833
round
Vcone=71.96

vcone=71.95 in^3

The employees at retail store earn $8.75 per hour. They can earn 1.5 times their hourly wage for every hour they work over 40 in
AnnZ [11894]
At a wage of 8.75 per hour, total earnings for 40 hours would be 350. Calculate overtime at 8.75 times 1.5 which equals 13.13. Then, multiply 13.13 by 12 to get $158. So the total is 350 + 158 = 508, likely around 480 after taxes for the US.

Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.
Svet_ta [12268]

Answer:

x=9,-1 and x^2+(-8)x=9

Explanation:

We are given the quadratic equation x^2-8x-9

, which we then compare with the standard form of a quadratic. The general quadratic is identified as ax^2+bx+c=0

. From our given equation, it follows that a=1,b=-8,c=-9

. To calculate the discriminant, we insert these values into the formula D=b^{2}-4ac

D=(-8)^2-4(1)(-9)=100

. Now, to find the value of x

The formula is x=\frac{-b\pm\sqrt{D}}{2a}

. The resulting equation will be obtained by rewriting the original equation through rearranging 9 to the right side and applying negative signs within brackets to convert the expression into the form of

x^2+bx=c

.

A direct variation function contains the points (–8, –6) and (12, 9). Which equation represents the function? y = –4/3x y = –3/4
Zina [11976]

Answer:

First, we must calculate the slope

m=Y2-Y1/X2-X1

= 9 - (-6) / 12 - (-8)

= 15/20

= 3/4

Therefore, the equation with the slope of 3/4 is Y=3/4x

<span>If the gratuity changes directly with the number of guests, which formula outlines the connection between the gratuity, t, and the number of guests, g? 
t = 1.8g t = g/18 g = 1.8t g = t/18
</span>
18/10 = 1.8
36/20 = 1.8
54/30 = 1.8
