Answer:
Amount of commission = $230
Step-by-step explanation:
Given:
Total sales = $2,300
Commission percent = 10%
Find:
Amount of commission
Computation:
Amount of commission = Total sales x Commission percent
Amount of commission = $2,300 x 10%
Amount of commission = $230
Answer:
1).
2).
Step-by-step explanation:
Here the given equation is 
We have to factor the perfect square trinomial on the left side of the equation
So left side of the equation is 
= 
since [(a+b)²= a²+b²+2ab]
Therefore the factorial form of the equation will be

Now we have to solve the equation by applying square root property


Answer: the percent of study group students from outside the state is 13%
Step-by-step explanation:
The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%
The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.
Since the rest are from outside the state, the percent of study group students from outside the state would be
100 - (80 + 7) = 100 - 87 = 13%
Answer:
Given coordinetes of triangle A(−2,3),B(8,3) and C(6,7)
AB=

If ABC is a right angled triangle, then square of one side must be equal to sum of suare of other two sides.
AB

=100
and AC

)
2
+(
20
)
2
=100
∴AB

=AC
2
+BC

thus triangle satisfies the Pythagoras theorem
Hence, the triangle is right angled triangle.
