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:
Step-by-step explanation:
p and h are number of plumbers and helpers, respectively.
Twenty workers earn a total of $2600
p+h = 20
h = 20-p
160p + 100h = 2600
160p + 100(20-p) = 2600
60p = 600
p = 10
h = 20-p = 10
Ten plumbers and ten helpers.
The unit for mass is grams, or g.
Hope this helps!
Answer:
A
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = ( multiply both sides by x³ )
x³y = 19 ( divide both sides by y )
x³ = ( take the cube root of both sides )
x =
Change y back into terms of x, then
(x) = = → A
Part a is 2x+5 because you add monday’s equation and tuesday’s
part b is 7x+2 because you add all equations together
