Answer:
Part a-
area= 35
perimeter= 31
part b-
area= 25
perimeter= 18
Step-by-step explanation:
to find the area of a triangle you multiply 1/2Bh
so for part A:
A= 
(10)(7) (honestly, you can just input the whole equation into the calculator)
A=(5)(7)
A= 35
and for part B:
A= (8.34)(6)
A= (4.17)(6)
A=25.02 (or just 25)
THEN, to find the perimeter you add up all of the sides
so for part A:
P= 14 + 10 + 7 = 31
and for part B:
P= 4 
+ 8 + 5 = 17 
or 18
I hope this helps :)
Answer:
The percentile rank of someone who earns $75,000 per year is the 85th percentile.
Step-by-step explanation:
Meaning of percentile:
When a value V is said to be in the xth percentile of a set, x% of the values in the set are lower than V and (100-x)% of the values in the set are higher than V.
In this question:
Working population of 10,500
8,925 people earn less than $75,000 per year.
8925/10500 = 0.85
0.85*100 = 85
The percentile rank of someone who earns $75,000 per year is the 85th percentile.
Answer:
-17.85
Step-by-step explanation:
=> y-x+z
Putting y = 4, x = 22 and z = 0.15
=> 4-22+0.15
=> -18+0.15
=> -17.85
The value of x that will make the proportion true is

Answer:
you get ten percent off but you didn't give the cost of the game
Step-by-step explanation:
The tax subtracts from the percent off, so 18%off - 8% sales tax =10% off
-18x-(-8y)=10 I think??? It's in standard form...
