A silversmith combined pure silver that cost $33.48 per ounce with 51 oz of a silver alloy that cost $24.35 per ounce. How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?

Answers

Answer 1

Answer:

$38.31

Step-by-step explanation:

Given:

Pure silver that cost $33.48 per ounce used to form $24.35 alloy/ounce.

Question asked:

How many ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce?

Solution:

At cost $24.35/ounce, pure silver is mixed = $33.48

At cost $1/ounce, pure silver is mixed = [tex]\frac{33.48}{24.35}[/tex]

At cost $27.87/ounce, pure silver is mixed = [tex]\frac{33.48}{24.35}[/tex][tex]\times 27.87 = \frac{933.08}{24.35} = 38.31[/tex]

Thus, $38.31 ounces of pure silver were used to make an alloy of silver costing $27.87 per ounce.

Answer:

Part A : [tex]1621\frac{1}{3}\pi[/tex] cubic meters.

Part B : 540π cubic cm.

Part C : [tex]V = \frac{4}{3}\pi r^{3}[/tex]

Step-by-step explanation:

Part A :

The volume of the silo includes the volume of a hemisphere and a cylinder.

So, the total volume

[tex]V = \frac{2}{3}\pi r^{3} + \pi r^{2}h[/tex]

⇒ [tex]V = \frac{2}{3} \times \pi (8)^{3} + \pi (8)^{2} (20)[/tex]

⇒ [tex]V = \frac{1024}{3}\pi + 1280\pi = 1621\frac{1}{3}\pi[/tex] cubic meters. (Answer)

Part B :

The volume of the cylindrical cup with height 15 cm and base radius 6 cm is given by

[tex]V = \pi r^{2}h = \pi (6)^{2} (15) = 540\pi[/tex] cubic cm.

Therefore, Mary can put 540π cubic cm of water in the cup with out it overflowing. (Answer)

If the arc on a circle measures 85 degrees, then the measure of the central angle is also 85 degrees too

so

The central angle in degrees is within the range [tex](0,90^o)[/tex]

Convert to radians

Remember that

To find, the value of [tex]-16(0.47)^2[/tex] = ?

∴ [tex]-16(0.47)^2[/tex]

6. Find the value of x.
19x - 36
6x + 31

Answers

Final answer:

To find the value of x, set the expressions equal to each other and solve for x.

Explanation:

To find the value of x in the given equation, we need to set the two expressions equal to each other and solve for x. So, we have:

19x - 36 = 6x + 31

Subtracting 6x from both sides, we get:

13x - 36 = 31

Adding 36 to both sides, we get:

13x = 67

Dividing both sides by 13, we get:

x = 67/13

So the value of x is approximately 5.15.

Tony believes that x = -9 is a root of the polynomial x^2 + 13x + 36. Erika, however, believes that x = 4 is a root of the same polynomial. Who is correct?

Answers

Tony is correct.

Step-by-step explanation:

Given polynomial is;

Tony's answer is x = -9

We will put x = -9 in given polynomial.

[tex](-9)^2+13(-9)+36=0\\81-117+36=0\\0 = 0[/tex]

Tony's solution satisfies the equation.

Erika's answer is x = 4

We will put x = 4 in given polynomial.

[tex](4)^2+13(4)+36=0\\16+52+36=0\\104\neq 0[/tex]

Erika's solution does not satisfy the equation, therefore

Tony is correct.

What is a straight line?

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have a linear equation in the form of slope:

y = 5.5x

Slope of the line m = 5.5

Slope is positive, which means the line goes down to up.

We can plot the graph of the equation y = 5.5x

Option first On a coordinate plane, x-axis is numbered negative 5 to positive 5 in increments of 1, and the y-axis is numbered negative 27.5 to 27.5 in increments of 5.5. A straight line with a positive slope begins at point (0, 0) and ends at point (5, 27.5) is correct.

Answers

Answer: [tex]y=0[/tex]

Step-by-step explanation:

The complete exercise is attached.

For this exercise it is important to remember:

1. The Product of powers property. This property states that:

[tex](a^m)(a^n)=a^{(m+n)}[/tex]

2. The multiplication of signs:

[tex](+)(+)=+\\(-)(-)=+\\(-)(+)=-\\(+)(-)=-[/tex]

Then, given:

[tex]8^3*8^{-5}*8^y=8^{-2}=\frac{1}{8^2}[/tex]

You can identify that [tex]8^{-2}[/tex] is obtained by applying the Product of powers property:

[tex]8^{3+(-5)+y}=8^{-2}=\frac{1}{8^2}[/tex]

Based on the explained above, you can write the following equation:

[tex]3+(-5)+y=-2[/tex]

Therefore you must solve for the variable "y" in order to find its value. You get that this is:

[tex]3-5+y=-2\\\\-2+y=-2\\\\y=-2+2\\\\y=0[/tex]

Answer:

You're trying to find the value of y that would result in 8^-2. When you multiply terms with the same base, you can add the exponents. 3+-5=-2 and -2-(-2) equals 0, so therefore y is equal to 0.
