The welder needs to cut off 9 3/8 inches from the longer piece.
To determine how much the welder needs to cut off from the longer piece of pipe, we need to find the difference between the lengths of the two pieces.
Given that the longer piece is 28 1/8 inches and the desired length is 18 3/4 inches, we can subtract the desired length from the longer piece's length:
28 1/8 - 18 3/4 = 9 3/8
Therefore, the welder needs to cut off 9 3/8 inches from the longer piece of pipe.

x = 39
x = 29
y = 61
y = 29
z = 61
z = 29
answer:
x = 29
y = 29
z = 61
step-by-step explanation:
all angles in a triangle must equal 180 degrees.
we were already given the angle degree of 61 degrees so we must include that in our formula to determine the degree of y.
the line in the middle already gives us two more angles because they both are 90 degrees for being a perfect quarter turn.
so to figure out y,
we must add 61+90 and then subtract the sum of that from 180.
so, 61+90 = 150 and 180-151 = 29
therefore,
we can conclude that y = 29
now, to determine the degrees of x and z we do the same thing.
we already know one angle equals 90 degrees.
180-90 = 90
that concludes that x and z must have a sum of 90.
if we use our choices,
39+61 = 100 (no)
39+29 = 68 (no)
29+61 = 90 (CORRECT)
29+29 = 28 (no)
therefore, x = 29 and z = 61
so, in total :
x = 29
y = 29
z = 61
hope this helps :)

level after I day was 5380 bacteria per cubic centimeter.
Answer: the function N(t) to estimate the level of contamination in the lake is:
N(t) = -1110 ln(t) - 230t + 1110 ln(I) + 230I + 5380
Step-by-step explanation: ∫ dN/dt dt = ∫ (-1110/t² -230) dt
N(t) = -1110 ln(t) - 230t + C
N(I) = -1110 ln(I) - 230I + C = 5380
C = 1110 ln(I) + 230I + 5380

The total that Robert had to pay for the car will be $1,575.
The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Robert bought a used car for $1,500. If the sales tax is 5%.
Let 'x' be the total price that he paid. Then the equation is calculated as,
5% = [(x - 1500) / 1500] x 100
Simplify the equation, then we have
0.05 = (x - 1500) / 1500
75 = x - 1500
x = 1500 + 75
x = $1575
The total that Robert had to pay for the car will be $1,575.
