Answer:
first and third
Step-by-step explanation:
Emma used the product instead of the quotient and forgot the parentheses in x-4.5
Answer
C. The relationship is proportional with the point (1,60) representing the unit rate.
Explanation
Let’s say 2 variables are x and y
Now give those 2 variables names
x = number of trainers sold
y = profit
A proportional relationship is one where 2 variables are related by some constant k
e.g y = kx
As x increases so does y. So as more trainers are sold more profit is made.
If there is no relationship the points will be scattered in the diagram however here they have a perfect linear relationship.
Unit rate, is the rate that the y variable increases as the x variable increases by 1.
Which in this instance is 60 for every 1 increase in x value.

Answer:
the answer would be 70/100 in fraction form, 70% in percent, and (i believe) 0.7 min decimal form. Hope this helps!
Answer:
A
Step-by-step explanation:
because she said half of X so 1/2x and then +3 to that half
Answer:
The appropriate answer will be "Y = 157.09 N/m³".
Step-by-step explanation:
The given values are:
Diameter
= 7.5 ft
= 0.3048 meter
Height
= 20ft
= 6.096
Weight density
= 45.93 lb/ft³
= 16.0184634 kg/m³
Acceleration
= 9.807 m/s2
As we know,
The specified density of weight can be expressed as:
⇒ Specific weight = density × acceleration
i.e.,
⇒
On substituting the estimated values in the above expression, we get
⇒
⇒
