Answer:

40/3; 13.3333333333333

Step-by-step explanation:

The volume of the cone is:

(1/3)(pi)(r^2)(h) =

(1/3)(pi)(10^2)(10) =

1000pi/3

The volume of the cylinder is:

(pi)(r^2)(h) =

(pi)(5^2)(h) =

25pi(h) = 1000pi/3 -->

pi(h) = 40pi/3 -->

h = 40/3

If (14,25) and (9,-10) are two anchor points on a trend line, then find the equation of the line.

posledela

Answer:

y= 7x-73

Step-by-step explanation:

the equation form is y=mx+c where m is the slope and c a constant

m= (25-(-10))/14-9 = 35/5 = 7

so y= 7x+c

replace x and y by 14 and 25 respectively

25 = 7*14+c

c= 25-7*14

c = -73

so y= 7x-73

Five carpenters worked 15 & 3/4, 15 & 1/4, 17 & 1/2, 12 & 1/2 and 17 & 1/2 hours respectively. What was the

azamat

<u>The total </u><u>labor cost</u><u> of the carpenters is $2296.91</u>

The carpenters worked $15\frac{3}{4} , 15\frac{1}{4}, 17\frac{1}{2}, 12\frac{1}{2}, 17\frac{1}{2}$

<h3>Conversion of Fraction</h3>

Let's convert the mixed fraction to improper fraction

So, we would have

63/4,
61/4,
35/2,
25/2
35/2.

<h3>Working Cost</h3>

Let's sum it up and multiply by the working cost per hour

$63/4 + 61/4 + 35/2 + 25/2 + 35/2 =78.5$

The total labor cost is = total hours worked * hourly rate.

This becomes $78.5*29.26=2296.91$

<u>The total labor cost is $2296.91</u>
