Answer: it contains 200 grams of zinc.

Step-by-step explanation:

Ratio of zinc to copper is 4 to 15 = 4;15

Total ratio = 4+15= 19

We first find amount of both zinc and copper( the whole chemical)  which is equal to

ratio of copper / total ratio  x (the entire chemical--total grams of zinc and copper) =amount of copper

15/19 x X = 750

X= 750 X 19 / 15= 950 grams

To find amount of zinc in the chemical = ratio of zinc / total ratio x total amount of chemical

=4/19 x 950

=200 grams

Find the product 12.34.0.74.91
Fantom [35]
<span>You are given the factors 12.34.0.74.91. The dots between the factors mean ‘to multiply’. Multiplying 12 by 34 by 0 by 74 by 91 would result to zero. The product of the given numbers is 0. This is due to the zero property of multiplication. Any number multiplied by zero is equal to zero. No matter how long the number you are going to multiply it, if there is a zero between the factors, the answer will always be zero.</span>

How to find the distance AB ? A(0,1) B(2,-3)
Anastaziya [24]

Hey there!!

Distance formula :

\sqrt{(y2-y1)^{2} + (x2-x1)^{2}  }

Coordinates given :

( 0,1 ) and ( 2,-3 )

( y2 = -3 ; y1 = 1 ) ( x2 = 2 ; x1 = 0 )

Plugging in the values :

... \sqrt{(-3-1)^{2}+(2-0)^{2} }

... \sqrt{(-4)^{2}+(2)^{2} }

... \sqrt{16+4}

... \sqrt{20}

... \sqrt{5}×\sqrt{4}

... 2\sqrt{5} units is the distance.

Hope my answer helps!!

What are the ordered pairs of the solutions for this system of equations?
Scorpion4ik [409]

Answer:

<em>( 4, 11 ) , ( - 4, 27 ) </em>

Step-by-step explanation:

f(x) = x² - 2x + 3

f(x) = - 2x + 19

x² - 2x + 3 = - 2x + 19

x² - 16 = 0

( x + 4 )( x - 4 ) = 0

x_{1} = - 4

x_{2} = 4

f(x) = y_{1} = - 2( - 4 ) + 19 = 27

y_{1} = 27

f(x) = y_{2} = - 2( 4 ) + 19 = 11

y_{2} = 11

<em>( 4, 11 ) , ( - 4, 27 )</em>
