Answer:
Proportion states that the two ratios or fractions are equal.
As per the given statement:
f the feed per revolution on an upright drilling machine is set to 1/64" and the rpm is set to 105.
Let x represents the revolutions are required for the drill to advance
into the part.
By definition of proportion:
![\frac{\frac{1}{64} }{105} = \frac{\frac{17}{8} }{x}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B1%7D%7B64%7D%20%7D%7B105%7D%20%3D%20%5Cfrac%7B%5Cfrac%7B17%7D%7B8%7D%20%7D%7Bx%7D)
By cross multiply we have;
![\frac{x}{64}= 105 \cdot \frac{17}{8}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B64%7D%3D%20105%20%5Ccdot%20%20%5Cfrac%7B17%7D%7B8%7D)
Multiply both sides by 64 we get;
![x = 105 \cdot 17 \cdot 8](https://tex.z-dn.net/?f=x%20%3D%20105%20%5Ccdot%2017%20%5Ccdot%208)
Simplify:
![x = 14,280](https://tex.z-dn.net/?f=x%20%3D%2014%2C280)
Therefore, 14,280 rpm revolutions are required for the drill to advance
into the part
Your answer is F.
It says she walks at a rate of 4 miles PER hour. If there is a word “per” that means you are multiplying which gives you 4p.
Lastly, it says she has a goal of walking AT LEAST 18 miles. That means 4p must be same or greater than 18.
Hey! you should use symbolab online for geometry it helps a lot!
Answer:
B. y = 2x + 1
Step-by-step explanation:
Substitute the information into the point-slope form equation.
y - y₁ = m(x - x₁)
y - (-5) = 2(x - (-3)
y + 5 = 2(x + 3)
y + 5 = 2x + 6
y = 2x + 1
