Answer:
D
Step-by-step explanation:
In scientific notation, the number that is being multiplied by the power of ten must be greater than or equal to 1 and less than 10. This eliminates options B, C, and E. The rest of the options are all 5.79 times something. To find that something, we can do 5,790,000 / 5.79 = 1000000 = 10⁶. This means that the answer is D.
The ratio of one triangle to the other (because they are similar, since the top angles are both 44 degrees and the two sides on the other sides of them are the same) is 12:8, or 3:2.
So therefore, we can say it's 9:6, so DE is 6.
Answer:
<h2>
(A.C.) 54 - 36 = m</h2>
Step-by-step explanation:
36 + m = 54 <em>subtract 36 from both sides</em>
36 - 36 + m = 54 - 36
m = 54 - 36
m = 18
sin = opposite/hypotenuse
sin 40° = 12/x
Cross multiply.
0.64278760968x = 12
Divide both sides by sin 40°.
x = 18.7 (rounded to nearest tenth).
The answer is C
y=kx. where k is a constant
sub y=34,x=2
2k=34
k=17
