in a certain chemical, the ratio if zinc to copper is 3 to 16. a jar of the chemical contains 320 grams of copper. how many gram
Dennis_Churaev [7]

Answer:

60 grams

Step-by-step explanation:

For these type of questions, we can equate the ratio with the actual amounts. We will let the quantity to find be an unknown variable, such as x. Then we equate the ratios, cross multiply, and use algebra to solve.

Let grams of zinc be "x", so we can write the ratios and actual amounts as:

\frac{3}{16}=\frac{x}{320}

Then we cross multiply and solve for x, what we want to find out. Shown below:

\frac{3}{16}=\frac{x}{320}\\16x =3 * 320\\16x = 960\\x = \frac{960}{16}\\x=60

There are 60 grams of zinc.

Find the value of x to the nearest tenth.<br> 46°<br> Х<br> 20°
GREYUIT [131]

Answer:

x = 14.7

Step-by-step explanation:

law of sines:

sin 20°/7 = sin 46°/x

x ·sin(20°) = 7 ·sin(46°)

x = 7 ·sin(46°) / sin(20°)

x = 14.722

The maximum value of P = x + 6y subject to the constraints is 9

<h3>How to determine the maximum value?</h3>

The objective function is given as:

P = x + 6y

The constraints are given as:

2x + 4y ≤ 10

x + 9y ≤ 12

x≥0 y≥0

Rewrite 2x + 4y ≤ 10 and x + 9y ≤ 12 as equations

2x + 4y = 10

x + 9y = 12

Divide 2x + 4y = 10  through by 2

x + 2y = 5

Subtract x + 2y = 5 from x + 9y = 12

x - x + 9y - 2y = 12 - 5

Evaluate the difference

7y = 7

Divide by 7

y = 1

Substitute y = 1 in x + 2y = 5

x + 2(1) = 5

Solve for x

x = 3

So, we have

(x, y) = (3, 1)

Substitute (x, y) = (3, 1) in P = x + 6y

P = 3 + 6 * 1

Evaluate

P = 9

Hence, the maximum value of P = x + 6y subject to the constraints is 9

One side of triangle is one-third the longest side. the third side is 11 11 feet less than the longest side. the perimeter is 73
Black_prince [1.1K]
Let x represent the longest side. Then the perimeter is
.. x + (1/3)x +(x -11) = 73
.. (2 1/3)x = 84 . . . . . . . . . . collect terms, add 11
.. x = 84*(3/7) = 36

The sides are 36, 12, 25.
