Answer:
figure it out bi
Step-by-step explanation:
Answer:
The answer is A.
Step-by-step explanation:
A. 3*(-9)= -27, 4*(-9)= -36, -27-(-36)= 9
B. 3*(-27)= -81, 4*(-9)= -36, -81- (-36) = -45
C. 3*3= 9, 4*9= 36, 9-36= -27
D. 3*(-3)= -9, 4*(-6)= -24, -9-(-24)= 15
Answer:
$4.17
Step-by-step explanation:
I'm guessing you meant 1lb instead of 1b so I will answer based on that. Since you pay $1.19 for one pound you can multiply that by 3.5, multiply 1.19 by 3 and than half of 1.19, or add 1.19 three times than add half of it once. Anyway you do it you get your answer of $4.165 which rounds to $4.17 your answer.
Answer:
Length DE= 2√2
Length EF= 2√2
Step-by-step explanation:
The 45-45-90 rule is very special but this question is really simple. You have all the angles and one side.
STEPS:
1) Take 45 from angle D and use its sine to find side EF
2) sin45= x/4 => 2.82 or 2√2
3) Take either cos45 from angle D or use Pythagoras since we now have enough side lengths to use Pythagoras (faster for me to use cosine).
4) cos45=x/4 => 2.82 or 2√2
Further explanation:
If you don't understand the sine and cosines, here's a word play to help.
S O/H
C A/H
T O/A
S=Sine
C=Cosine
T= Tangent
O= Opposite
H= Hypotenuse
A= Adjacent
If you search a video on this word play it will help more since it is visual.
Good luck.
