Answer:Assuming a 3-inch diameter, pillar candles of 3, 4 and 6 inches in height will burn for 45, 60 and 75 hours, respectively. Three-inch Party Lite pillar candles will burn 30-35 hours; 5-inch, 65 to 70 hours; and 7-inch, 90 to 95 hours. The three-wick 6-by-5-inch candles burn for more than 100 hours.

What is the slope of a line perpendicular to the line passing through E(-1,6) and F(-2,-10)?
STatiana [176]

Answer:

Step-by-step explanation:

E(-1,6)  & F(-2,-10)

Slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\\\\  \  \ \ = \frac{-10-6}{-2-[-1]}\\

=\frac{-10-6}{-2+1}\\\\=\frac{-16}{-1}\\\\= 16

Slope of the line perpendicular to this line = -1/m =  -1/16

Mr lim had just enough money to buy 6 similar lamps. However, he bought 3 such lamps and had $950 left. How much money did mr li
Artyom0805 [142]

Let the cost of a lamp = x

6 lamps would cost 6x

He bought 3 lamps at 3x plus Thad 950 left.

3 lamps plus the 950

Would be the same amount as 6 lamps:

Set up an equation and solve for x:

3x + 950 = 6x

Subtract 3x from both sides:

950 = 3x

Divide both sides by 3:

X = 316.67

Each lamp was $316.67

Multiply the price of a lamp by 6:

316.67 x 6 = 1900

He had $1900

butalik [34]
Area = (theta/360)* pi * r^2 
where theta is the angle of  the sector 
subs by your givens in the above equation 
2.512 = (theta/360) * pi * (4)^2 
theta = (2.512 * 360) /(pi*(4)^2)
theta = 18 degree
