Answer:
Remove 9 from triangle B to A
Step-by-step explanation:
Given
Three Triangles
A: 1,2,3
B: 7,8,9
C: 4,5,6
Required
Make their sum equal
First, we need to calculate the sum in each triangles;
Remove 9 from triangle B to A
At this point, we have:
<em>Hence, the solution is to remove 9 from B to A</em>
Answer:
0.78 euros per dollar
Step-by-step explanation:
If 35 euros=$45.00, then every dollar that he has is equivalent to (35/45) euros=35/45=0.78 euros per dollar
(I found the answer from Nonicorp1 on Brainly)
Ratio of girls to boys is 3:2....added = 5.....this means that 3/5 of the total students are girls and 2/5 of the total students are boys.
so if there are 50 students...
3/5(50) = 150/5 = 30 girls
2/5(50) = 100/5 = 20 boys
7 mph. 28 divided by 4 is 7. Or 7 miles in one hour
Usually, Δ stands for a difference: if you have two quantities a₂ and a₁, their difference a₂-a₁ can be shortened as Δa.
This said, your formula is not set up correctly: the linear speed can be found with the formula:
v = ω·r
where r is the radius and <span>ω is the angular frequency, which is given by:
</span>ω = Δα / Δt
Substituting this into the one above, you find the correct formula:
<span>v = (Δα / Δt) · r
The problem gives you directly </span>Δα, which is 1/3 rad, because does not say at what angle the point started moving and at what angle it stopped.
Similarly, for the time you have Δt, which is 20 s.
Therefore, plugging in the numbers you get:
v = (Δα / Δt) <span>· r = (1/3 </span>÷ 20) × 10 = 1/6 = 0.167 cm/s
