Answer:
7kg
Step-by-step explanation:
mass: amount of matter in a substance,
SI Unit: kg
It has nothing to do with N (weight) in this case so take the kg value as the mass
Answer:
0.71 kg
Step-by-step explanation:
a common equation in physics is w = mg
we can rearrange this to m = w/g
g is the acceleration of gravity: 9.81 m/s^2
w is the weight of the given equation of the object: 7 kg
so m = 7 kg ÷ 9.81 m/s^2
this gives us: m = 0.71 kg
Answer:
The expression that describes the width of Kevin’s yard is (3g + 12) feet
Step-by-step explanation:
This is an expression problem.
From the question, we are made to know that the width of the yard is 3 times the width of the garage increased by 12 feet.
Now, we are told that the width of the garage is g feet and we want to find the width of the yard.
The width of the yard will be g feet * 3 + 12
Mathematically that would be 3g + 12 feet

c.7
d.11
Answer:
Option (d) is correct.
Step-by-step explanation:
Given : Equation of line 3x + y = -2
We have to choose the correct graph for the given equation of line 3x + y = -2
Consider the given equation of line 3x + y = -2
We find the points that satisfies the equation of line and plot these to find the equation of line.
Put y = 1
We get
3x + 1 = -2
3x = -2 -1 = -3
x = -1
also, put y = 4
We get
3x + 4 = -2
3x = -2 -4 = - 6
x = - 2
also, when x = 0 , we get, y = -2
We get three points (-1, 1), (0,-2) and (-2, 4)
Now plot these point to obtain graph as shown below.
