Answer:
7)It is possible for two rectangles to have the same area but not the same perimeter 8) 8cm
Step-by-step explanation:
Answer:
875 square inches
Step-by-step explanation:
The lateral area of a triangular prism is the sum of the areas of the three rectangular faces:
13×25 +15×25 +7×25 = (13 +15 +7)×25 = 35×25
= 875 . . . square inches
_____
The area of a rectangle is the product of its length and width. As we have seen here, the lateral area is the product of the height of the prism and the perimeter of its base.
1 inch = 2.54 centimeters. this is a ratio.
expression: x inches * _2.54 centimeters_ = # of centimeters in x inches
1 inch
the reason the 1 inch is in the denominator is to cancel out the inches for x so that you are only left with centimeters.
estimate: 12 inch * _2.54 centimeters_ = 30.48 centimeters.
1 inch
Answer:
(3,-7)
(-8,48)
(-4,28)
(8,-32)
(-3,23)
Step-by-step explanation:
To solve, just put in the x value from the table as the x value in the equation. Then solve to get y.
Hope it helps!
For equations that model direct variation, they are of the form y = kx, where k is the constant of proportionality.
So, for there to be a constant of proportionality of 1/2, the equation should be y = 1/2 x.
This is the same as y = 3/6 x (since 1/2 = 3/6), so the answer is C.
