Answer:
A. 38% - 19/50
B. 4/5 - 80%
C. 17/25 - 0.68
D. 27/50 - 0.54
E. 0.45 - 45% or 9/20
Step-by-step explanation:
A. 19/50 - 38/100 - 38%
B. 4/5 - (times by 20 (the numerators and denominators)) - 80/100 - 80%
C. 17/25 - (times by 4 (the numerators and denominators)) - 0.68
D. 27/50 - 54/100 - 0.54
E. 0.45 - 45/100 - 9/20 - 45%
Answer:
126 cm^2
Step-by-step explanation:
The surface area of one cube face is (3 cm)^2 = 9 cm^2.
Each cube has 6 faces, but joining them together hides 4 of the faces. The surface area of the resultant solid is ...
(6·3 -4)·(9 cm^2) = 126 cm^2
Answer:
x=80
Step-by-step explanation:
because all lines intersect at point E, we could safety say they are equal. therefore, we can also say that angles aef+def=ceg+beg.
we already know what ceg+beg is; 160 and we also know what def is, which is 80.
we set up an equation plugging it in. we will say ceg=x.
x+80=160, subtract 80 on both sides and you get x=80!
hoped this helped :)
Answer:
Step-by-step explanation:
−7(−1+7k)−3(8k−1)
Distribute:
=(−7)(−1)+(−7)(7k)+(−3)(8k)+(−3)(−1)
=7+−49k+−24k+3
Combine Like Terms:
=7+−49k+−24k+3
=(−49k+−24k)+(7+3)
=−73k+10
Answer:
=−73k+10
Answer:
ok so it'll be the first one
