In A certain chemical, the ratio of zinc to copper is 3 to 19. A jar of the chemical contains 836 grams of copper. How many gram
Elis [28]

Answer:

The jar contains 132 grams of zinc

Step-by-step explanation:

zinc to copper = 3 : 19

New equivalent weights

zinc to copper = x : 836

Now, let us solve for x as follows

\frac{zinc}{copper}  = \frac{3}{19} = \frac{x}{836} \\\\cross-multiplying\\3 \times\ 836 = 19 \times\ x\\2508 = 19x\\x = \frac{2508}{19}\\x =  132

the jar contains 132 grams of zinc

To check if the answer is accurate, the answer gotten when the weight of zinc is divided by copper will be the same for both the old and new ratios:

old ratio: 3 ÷ 19 =  0.158

new ratio: 132 ÷ 836 = 0.158

When you apply a power to a product of two or more terms, you __________ the exponent.
Harlamova29_29 [7]
You multiply the exponent
Remember to MULTIPLY exponents (not add them) when you are raising a power to a power. In this case, (−3x3y2)4 = (−3)4(x3)4(y2)4 = −34 · x3·4 · y2·4.
