The perimeter of the triangular end is 12 m, so the total rectangular area is
.. (12 m)*(8 m) = 96 m^2
There are two triangles with base 3 m and height 4 m, so their total area is
.. (3 m)*(4 m) = 12 m^2
The surface area of the figure is the sum of these
.. 96 m^2 +12 m^2 = 108 m^2
Answer:
25
Step-by-step explanation:
Given the model:
y=−3.5x+400
Number of children in amusement park = y
Temperature = x
On a certain day:
Temperature = 90°F
Number of children in park = 60
Using the model :
The predicted number of children in park when temperature is 90°F would be :
y = - 3.5(90) + 400
y = - 315 + 400
y = 85
Model prediction = 85 children
Actual figure = 60
Residual :
|Actual - predicted | = |60 - 85| = 25 children
Answer:
A) y = -2x
B) y = x - 3
Step-by-step explanation:
A) you need to have a negative 'x' coefficient and no y-intercept
B) you need to have a positive 'x' coefficient and a negative y-intercept
Answer: 2in
Step-by-step explanation:
Hi, to answer this question we have to apply proportions:
The correct scale on the blueprint is : 1/4 inch represents 3 feet.
So, the proportion is: 1/4 inch/ 3 feet = (1/4) /3
For 24 feet:
x inches /24 feet = x/24
So:
(1/4)/3 = x/24
Solving for x (inches)
[(1/4)/3 ] (24) =x
x =2 inches
