Answer:
<u><em>5.25 inches or </em></u>
<u><em> inches</em></u>
Step-by-step explanation:
<u><em>I believe that the question is what do they multiply to..? If so, we start by </em></u><u><em>making them both in decimal form:</em></u>
<u><em>7 / 2 = 3.5</em></u>
<u><em>3 / 2 = 1.5</em></u>
<u><em>Now, we </em></u><u><em>multiply</em></u><u><em>:</em></u>
<u><em>3.5 * 1.5 = 5.25</em></u>
<u><em>If you want fraction form, we can turn .25 to 1/4.</em></u>
<u><em>Fraction form: </em></u>
Answer:
(x, y) = (8, -3)
Step-by-step explanation:
You can substitute for x in the first equation:
3(-3y -1) +3y = 15
-6y = 18 . . . . . add 3 and simplify
y = -3 . . . . . . . divide by -6
x = -3(-3) -1 = 8 . . . . find x using the second equation
The solution to this system of equations is (x, y) = (8, -3).
Answer:
B
Step-by-step explanation:
Sin(A) = O/H
Sin(A) = 27/45
Sin(A) = 0.6
This is the concept of application of trigonometry;
The height of the tree will be given by:
tan theta=opposite/adjacent
theta=65
opposite=h
adjacent= 10
thus;
tan 65=h/10
h=10 tan 65
h=21.45 m
The distance between the dog and the man is x;
the distance of the man to the tree is (x+10) m
this will be given by:
tan 50= 21.45/(10+x)
getting the reciprocal of the expression we get;
1/tan 50=(10+x)/21.45
cross multiplying the above expression we get;
21.45=(10+x)tan 50
21.45=(10+x)1.2
21.45=12+1.2x
1.2x=21.45-12
1.2x=9.45
x=9.45/1.2
x=7.875
We conclude that the distance of the Firefighter and the dog is x=7.875 m
Answer: Lydia’s new balance would be $12.26.
Explanation:
Deposit means add so,
-18.24+30.50=12.26
Now Lydia will have $12.26 in the account.
