Answer:
(a) 2.6 m^2
(b) 3.9 m^3
Step-by-step explanation:
(a)
ABCD is a trapezoid.
A = (B + b)h/2
A = (1.7 m + 2.3 m)(1.3 m)/2 = 2.6 m^2
(b)
The skip is shaped like a prism with trapezoidal bases.
V = area of base * height
V = 2.6 m^2 * 1.5 m = 3.9 m^3
Answer:
A
Step-by-step explanation:
if the rule is (-x,y) then that just means the x changes
(3,-2) changes to (-3,-2)
Let pc be pencils, and pn be pens. Then:
5pc+pn=250
pc+2pn=185
Then
10pc+2pn=500
pc+2pn=185
9pc=315
pc=35
pn=75
Pencils are 35 cents; pens are 75 cents
