Answer:
1. Proportional
2. Not proportional
3. Proportional
Step-by-step explanation:
Mike's proportion
Michael gave $1.32 tip for an order that cost $8.80
$1.32÷$8.80=0.15
Given
1. $2.22 for $14.80
$2.22÷$14.80 =0.15
It is proportional to Mike's tip
2. $1.86 for $10.50
$1.86÷$10.50=0.1771
It I not proportional to Mike's tip
3. $0.78 for $5.20
$0.78÷$5.20=0.15
It is proportional to Mike's tip
Therefore,
1. Proportional
2. Not proportional
3. Proportional
Answer:
The distance between the origin and the given point is 13.9283 units.
Step-by-step explanation:
The coordinates of origin are (0,0,0)
We are given a point R(9,7,80
The distance formula:
, where 
are coordinates of one point and 
are coordinates of other point.
Putting the values as:
We get d = 
d = 
d = 13.9283
Thus, the distance between the origin and the given point is 13.9283 units.
The answer in the last one
Answer:
2388.16 in³
Step-by-step explanation:
volume of figure will be calculated by adding the volume of cuboid and cylinder . The formulas are l×b×h and pi ×r²×h respectively.
This system of equation has an infinite number of solutions.
You can tell this because multiplying one equation by a constant gives you exactly the other equation. You can multiply the second equation by 3.
9x - 6y = 15
5(3x - 2y = 5) = 9x - 6y = 15
When this happens, you can assume that there are an infinite number of solutions.
