Answer:
total area = 193.31 m²
Step-by-step explanation:
rectangle area = 7 x 15 = 105 m²
semi circle area = (3.14)(7.5²)/2 = 88.31 m²
total area = 105 m² + 88.31 m² = 193.31 m²
Answer:
total is 47.70
Step-by-step explanation:
change is $12.30
Answer:
y= -7
Step-by-step explanation:
y=ax+b
Find a where a=y2-y1 /x2-x1
y2=13,y1=5 x2=5,x1=3
substituting the values
a=13-5/5-2
a=8/2
a=4
substituting a into the formular
y=4x+b
taking x and y values let say 3 and 5 for x and y
the equation becomes
5=4(3)+b
5=12+b
5-12=b
-7=b
substituting the values of a and b into the equation
y=4x-7
when x=0
y=4(0)-7
y=0-7
y=-7
so when x=0,y=-7
