Answer:
x=7°
Step-by-step explanation:
The figure is a triangle.
1. Triangles's angles add up to 180°.
2. We know that 1 angle measures 104°, so the remaining 2 angles add up to 76°. It is an isosceles triangle, so both of the remaining 2 angles have equal measures.
3. 76÷2=38°.
4. 9x-25°=38°
5. 63°-25°=38°
6. 9x=63°
7. x=7°

Answer:u=1/16
Step-by-step explanation:
u is inversely proportional to v^2
u=k× 1/v^2
u=k/v^2
When U=4/9 when v=3
4/9=k×1/3^2
4/9=k×1/9
4/9=k/9
Cross multiply
4×9=k×9
36=9k
Divide both sides by 9
36/9=9k/9
4=k
When v= 8, u=?
u=k/v^2
Recall k=4
u=4/8^2
u=4/64
u=1/16
Answer:
12 boys
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 3 × 16 = 48, 48 ÷ 4 = 12
I hope this helps!
K=2. You have to divide 3.2 by 4, then divide both sides by 0.8, finally, you have your answer, K=2.
