We see that the shape is made up of 2 shapes:
trapezoid and triangle
(trapezoid is on top of upside down triangle)
area of trapezoid=(1/2)(b1+b2)(h)
area of traignel=(1/2)(b)(h)
area of trapezoid
b1=14
b2=18
h= ok so total height=17 and 12 is taken up by triangle os therefor h=17-12=5
A=(1/2)(14+18)(5)
A=(1/2)(32)(5)
A=(16)(5)
A=(80)
now area of triangle
H=12
B=18
A=(1/2)(18)(12)
A=(9)(12)
A=108
add
80+108=188
total area=188mm^2
Answer:
C: 3-a
Step-by-step explanation:
The answer is C because an algebraic expression needs to have a variable in it. The variable is "a," so the answer has to be C.
To determine the actual length of a regular car, we just have to divide the given length by the scale factor. That is,
actual length = (6.25 in) / (1/16) = 100 inches
If the ratio of the model car is 2:32, the answer would still be the same considering that 2:32 can still be reduced to 1:16.
Answer:162
Step-by-step explanation:
(X+7)/13=13/1
Cross product
X+7=169
X=169-7
X=162
