A metalworker has a metal alloy that is 30% copper and another alloy that is 65% copper. How many kilograms of each alloy should
LenKa [72]

Step-by-step explanation:

If x is the mass of 30% copper alloy, and y is the mass of 65% copper alloy, then:

x + y = 80

0.30x + 0.65y = 0.51(80)

Solving the system of equations using substitution:

0.30x + 0.65(80 − x) = 0.51(80)

0.30x + 52 − 0.65x = 40.8

11.2 = 0.35x

x = 32

y = 80 − x

y = 48

The metalworker needs 32 kg of 30% copper alloy and 48 kg of 65% copper alloy.

If m and n are positive integers such that the greatest common factor of <img src="https://tex.z-dn.net/?f=%20m%5E%7B2%7D%20n%5E
torisob [31]
The greatest common factor of m^{2}  n^{2} and m n^{3}

is
 
gcd(m*m*n*n, m*n*n*n) =m*n*n=m n^{2}

what we did, was to see how many m's and how many n's, each expression have, and then pick the smallest of each letter (factor).

the reason is that the common factor, must have enough m's and n's to divide the m's and n's of both expressions

so
45=m n^{2}
also 
45=5*9=5*3^{2}

thus, n is equal to 3

Answer:

T = ±22

Step-by-step explanation:

Let's solve your equation step-by-step.

0=−16t2+7744

Step 1: Add 16t^2 to both sides.

0+16t2=−16t2+7744+16t2

16t2=7744

Step 2: Divide both sides by 16.

16t2

16

=

7744

16

t2=484

Step 3: Take square root.

t=±√484

t=22 or t=−22
