Answer:
Reflection
Step-by-step explanation:
It is reflecting across the Y axis. It is not a dialation, since it is the same shape, but not a different size. Its not rotation, because it wasnt rotated to get to the new shape. And it is not translation, because it is not exactly the same shape (the shape was mirrored)
Answer:
4a)= 2.1m 4b)= 1.9 m 5)= 29.6º
Step-by-step explanation:
4a):
x is the opp
AB is the hyp
BC is the adj
thus,
sin32 = x/4
cross multiply, x= 4*sin32
x= 2.1196.......
x=2.1 m
4b).
x is the hyp
ac is the opp
bc is the adj
thus,
cos65=4.5/x
cross multiply, x= 4.5*cos65
x=1.9017....
x=1.9 m
5).
AB is the opp
bc is the adj
ac is the hyp
thus:
tanC= 2.1/3.7
C= tan^-1 (2.1/3.7)
C= 29.5778.....
C= 29.6º
Answer:
24
Step-by-step explanation:
Let Noah = x. I will write the equation in order of appearance with Noah first.
x + 3x + (3x + 5) + (3x + 12) + (x - 4) + 2(x-4) = 317
Distribute where needed and remove parentheses
x + 3x + 3x + 5 + 3x + 12 + x - 4 + 2x - 8 = 317
Collect like terms
13x + 5 = 317
Move the constant to the right of the equal sign and do the math
13x = 312
Divide both sides by 13
Noah sold 24 cookies
