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

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

If the point (3,5) is on f(x) find the corresponding point on the graph of y=(x+2)+1
ad-work [718]

The corresponding point to the point given (3,5) which is on the graph of f(x) as described in the task content is; (3,6).

<h3>What is the corresponding point to the given point (3,5) as given in the task?</h3>

It follows from the task content that the point given originally is; (3,5).

However, it is required that the point which is equivalent to the given point on the graph of y=(x+2)+1 be identified.

It therefore follows that the point required as in discuss is;

y = (3+2) +1

y = 6.

Hence, the corresponding point is; (3,6).

Please help :C I have to get this question done asap or I'll get into trouble

Ok, so it seems to be the square root of the cube root of 2

we just convert to exponential
remember
(x^m)^n=x^{mn} and
\sqrt[n]{x^m} =x^ \frac{m}{n}


therfor

\sqrt{ \sqrt[3]{2} }= \sqrt{2^ \frac{1}{3} } =( 2^ \frac{1}{3})^ \frac{1}{2} =2^ \frac{1}{6}


last choice is correct

Mrs Adams baked some muffins. Carl eat 2/5 of the muffins and John eat 25. How many muffins were baked?
Dennis_Churaev [7]

Answer:


Well, how many were left over? Mrs. Adams has a muffin factory and made 1 million muffins. Carl ate 2/5 or 40% or 400,000 muffins, and John ate 25. 599,975 muffins were shipped for sale. That meets the stated requirements.


Hence, we have to guess there were supposed to be no muffins left over.


In that case, Mrs. Adams baked 125/3 muffins, Carl ate 2/5 of them = 50/3, leaving 75/3 = 25 for John.



Step-by-step explanation:

x muffins baked, 2/5 eaten by Carl, 3/5 left to be eaten by John, who ate 25 before running out.


3/5 x = 25

x = 25 × 5/3 = 125/3 = 41 + 2/3


Or, Start with x muffins. Carl ate 2/5 x, leaving 3/5 x. John ate 25 with zero left over. So 3/5 x = 25.


(x - 2/5 x) - 25 = 0

3/5 x = 25

x = (5/3) × 25 = 125/3.
