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:
By cross multiply we have;
Multiply both sides by 64 we get;
Simplify:
Therefore, 14,280 rpm revolutions are required for the drill to advance into the part
Answer:
12
Step-by-step explanation:
4 x 3 = 12
X= 70 degrees
Y= 70 degrees
Understand that every triangle has three angles and they add up to 180 degrees.
If I split this triangle in half the total degrees of each individual piece will be 90 degrees. A split in the isosceles triangle will also cause the 40 degrees to halved (thus, how I got 20 degrees in our 90 triangle).
Since we are dealing with an isosceles triangles two of the sides will be equal (hence, the dashes on the triangles sides). Therefore, x and y will also be equal.
Now if our 40 degreed angle is now 20 degrees, we have an unknown angle and the triangle in total now adds up to 90 degrees we can set up an equation.
20 + y = 90
Y = 70
Since X and Y are equal, X will also be 70.
If we return to to the isosceles triangle before it was split (use your photo for reference) and we add 40 +70 + 70 we will get 180 degrees. Which is the standard total of degrees for any triangle that is not a 90 degreed triangle.
I hope this helps. Feel free to ask questions.

Answer:
35000
Step-by-step explanation:
35,007 to the nearest hundred would be 35000 because 7 is between both 0 hundred (000) and 1 hundred (100). However, because 7 is only 7 away from 000 and 93 away from 100, 000 is the nearest hundred.
Hope this helps :)
Answer:
in picture
Step-by-step explanation:
— Round tables will have 6 chairs, rectangular tables will have 10 chairs, the total number of chairs must be at least 185: 6x +10y ≥ 185
— There be no more than 15 rectangular tables: y ≤ 15
— No fewer than 6 round tables: x ≥ 6
— Rectangular tables must be at least 1/3 the number of round tables: y ≥ (1/3)x ⇒ 3y ≥ x
