Answer:
trapezoid one is 336 inches squared
trapezoid two is 9 inches squared
Step-by-step explanation:
The formula for a trapezoid is b1+b2 so the number on the top line = the number on the bottom line, you then multiply your new number by the height which is the number bye the dotted red line.
Hope this helps!
Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
Answer:
7
Step-by-step explanation:
Given the following :
7 heart stickers and 14 star stickers :
The greatest number of pages that can be decorated using the stickers above without any left over ;
To get this we obtain the greatest common factor of 7 and 14
Factors of 14
14 : 1, 2, 7, 14
Factors of 7
7 : 1, 7
The greatest factor common in both numbers is 7
Hence, greatest number of pages that can be decorated without any leftover is 7
Answer:
2.75x + 114 = 320.25
x = $75
Step-by-step explanation:
2.75x + 114 = 320.25
number of hours of labor (2.75) times the cost per hour of labor (x) + cost of parts (114) = total cost (320.25)
2.75x + 114 = 320.25
subtract 114 from both sides
2.75x = 206.25
divide both sides by 2.75
x = 75
------------------------
check the math:
2.75(75) = 114 = 206.25 + 114 = 320.25
Answer:
38°
Step-by-step explanation:
90= (8+3x) + 52
38= 8 +3x
30= 3x
10= x
