Answer:
A = 16.5 cm²
Step-by-step explanation:
the area (A) of a trapezoid is calculated as
A =
h (b₁ + b₂ )
where h is the perpendicular height between bases and b₁, b₂ the bases
here h = 3, b₁ = 7 , b₂ = 4 , then
A =
× 3 × (7 + 4) = 1.5 × 11 = 16.5 cm²
So it cuts the y axis at -9 as it has a gradient of 0.
Therefore y=-9 is the equation, as y=mx+c, it intercepts at -9 and has a gradient of 0, therefore y=0x-9 so y=-9.
Answer:
the face area would be 25.0
and total area would be 150.0
Step-by-step explanation:
5.0*5.0=25.0
6*25.0=150
Answer:
Each shrub costs $9.75 and the equation will be 12.5 + 6x = 71
Step-by-step explanation:
Given, a customer bought some potting soil for $12.5 and 6 shrubs. All the shrubs were same price. Total expense was $71.00.
So, the equation will be:
12.5+ 6x = 71.....(i)
Here, x = price of the shrub as all the shrubs are same price.
Solving the equation number (i),
6x = 71-12.5
or, 6x = 58.5
or, x = 58.5/ 6
or, x = 9.75
So, each shrub will cost $9.75 each.
