Answer:
∠ A ≈ 16.67°
Step-by-step explanation:
Using the Sine rule in Δ ABC
= 
, substitute values
= 
( cross- multiply )
16 sinA = 8 sin35° ( divide both sides by 16 )
sin A = 
, thus
∠ A = 
( ) ≈ 16.67° ( to 2 dec. places )
Answer:
17 + 7 = 24
so ted had 24 pictures on the camera role
Hope this helps :)
so then do X + 7 = 24
Step-by-step explanation:
Answer:
<u>The solution for this system is x = 1/2 and y = 9/2</u>
Step-by-step explanation:
1. We have this system of equations:
x - 3y = -13 and 5x + 7y = 34
2. Let's try to find out the value of x on the first equation:
x - 3y = - 13
x = 3y - 13
3. Now, let's replace x on the second equation for finding y:
5x + 7y = 34
5 (3y - 13) + 7y = 34
15y - 65 + 7y = 34
22y = 34 +65
22y = 99
2y = 9 (Dividing by 11 at both sides)
<u>y = 9/2</u> (Diving by 2 at both sides)
4. Now, let's find out the value of x on the first equation, using the value of y:
x - 3y = - 13
x - 3 (9/2) = - 13
x - 27/2 = -13
x = -13 + 27/2
x = (-26 + 27)/2 (Adding - 13 and 27/2)
<u>x = 1/2</u>
5. Finally, let's prove the values of x and y are correct on the second equation of the system:
5x + 7y = 34
5 (1/2) + 7 (9/2) = 34
5/2 + 63/2 = 34
(5 + 63)/2 = 34
68/2 = 34
<u>34 = 34</u>
<u>It has been proved that x = 1/2 and y = 9/2 are correct</u>
Answer:
Step-by-step explanation:
means single part out of 5,
Since, 
Similarly, 
means 2 parts out of 10.
Now we can shade 2 parts out of 10 to show of the given figure.
(As shown in the figure attached)
I think the correct answer is option B. The system of equations given above will have only 1 solution. They will intersect only at 1 point when graphed in a x-y coordinate plane. Hope this answers the question. Please feel free to ask more questions.
