Answer:
The cost of a school banquet is $75+30n, where n is the number of people attending.
If 53 people are attending to visit school banquet, then you have to find the value of given expression at n=53.
At n=53, the value is $(75+30·53)=$1,665.
Step-by-step explanation:
The answer is Hx = ½ Wsin θ cos θ
The explanation for this is:
Analyzing the torques on the bar, with the hinge at the axis of rotation, the formula would be: ∑T = LT – (L/2 sin θ) W = 0
So, T = 1/2 W sin θ. Analyzing the force on the bar, we have: ∑fx = Hx – T cos θ = 0Then put T into the equation, we get:∑T = LT – (L/2 sin θ) W = 0
Answer:
231 cubed centimeters
Step-by-step explanation:
Find the area of the base of the pyramid
18 x 7=126 divided by 2= 63 cm
Next, make sure to the remember the formula is 
1/3(63)(11)=
21(11)=231
231 cubed centimeters is the answer.
Answer:
-14
Step-by-step explanation:
a·b = |a|×|b|×cos(angle between them)
= 4×7×(-1/2)
= -14
392 / 500 double and take one decimal place to see percentage
52/500
56/500 e.g. 56*2 = 112 now take 1 decimal so it is 11.2%
now divide each by 20
