MY GUESS: =====C: 4 inch
Step-by-step explanation:
12^2 + B^2 = 20^2
144+B^2 =400
200-144 = 56 = B^2
B^2 = 7.48331477355
7.48331477355 - 3 = 4ish inches
Answer: (I am copying and pasting my answer from the same question you did before in case you are waiting for an answer on this instead.)
1/2
Step-by-step explanation:
<em>To find the x-int of any equation, you will need to replace the y with a 0 since when the x-int is when y is 0.</em>
8x+2y = 4 ➨ 8x+2*0 = 4
<em>Now I will do 2*0 which anything times 0 is equal to 0. And we are left with the equation of:</em>
8x = 4
<em>Now I will divide both sides by 8, which isolates our x.</em>
x = 1/2
The x-int is 1/2.
Answer:
δx=0.035 m
Step-by-step explanation:
We use the expression of the uncertainty of x:
δx = (x/(vo cosθ))*sqrt((cosθ)² (δV₀)²+(V₀ sinθ)²(δθ)² )
First of all, we need to identify δV₀ and δθ. In our case δV₀ = 0.002 m/s and δθ = 0.0175 rad.
Remember: 1° = 0.0175 rad. This is very important to get the right answer here.
Now, we just need to replace the values we have into the equation δx:
δx = (0.5/(3.49*cos(76)))*sqrt((cos(76))²*(0.02)²+(3.49*sin(76))²*(0.0175)²)
δx = 0.035 m.
Have a nice day!
Answer:
x = 21
Step-by-step explanation:
x- 12 = 9
Add 12 to each side
x- 12+12 = 9+12
x = 21
Here is the solution.
Let s = small cups and l = large cups
s + l = 155
1.25s + 2.50l = 265
s = 155 - l
(now substitute)
1.25(155-l) + 2.50l = 265
193.75 - 1.25l + 2.50l = 265
1.25l = 71.25 (divide both sides by 1.25)
l = 57
Therefore there are 57 large cups sold
Next,
s + 57 = 155
s = 98
There are 98 small cups sold.
Hope this answers your question.
