Took the quiz.
Answer:
center of mass = ( 1 ,2 )
Step-by-step explanation:
attached below is the detailed solution of the problem
first we have to determine the value of m
M = ∫∫ dA
= 6
Mx = 12
attached solution below
My = 6
hence center of mass of a thin plate
x , y
= My/m , Mx/m
= 6/6 , 12/6
= ( 1, 2 )
Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.
Step-by-step explanation:
Given,
Cost of each flashlight = $12
Cost of each sleeping bag = $45
Total cost = $1785
Let,
x represent the number of flashlights ordered
y represent the number of sleeping bags ordered
According to given statement;
12x+45y=1785 Eqn 1
x = 5y Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 105

Putting y=17 in Eqn 1

Juanita and Keenan ordered 85 flashlights and 17 sleeping bags.
