at the metal-casting company where i work, i must set up a conveyor system to move castings from the furnace to the heat treatment area 55 yards away. the castings cool at the rate of 0.03 degrees fahrehnheit per second and must not be allowed to cool more that 7 degree's fahrenheit before being heat rtreated. what is the minimum speed per second that the conveyor must move?

Answers

Answer 1
Maximum time allowed = 7 deg. / 0.03 deg/s = 233.3 s
Minimum speed = 55 yd * 3 ft/yd / 233.3 s
= 0.707 ft/s

Two right triangles are congruent. Find the value of x.
right triangle with angle of 33 degrees, right triangle with angle of 9 x minus 15 degrees
Select one:
a. 5
b. 6
c. 8
d. 12

Answers

Given that the two right triangles are congruent, there are two possibilities.

9x - 15 is equal to the angle 33°  or 9x - 15 is equal to the other angle of the first triangle.

Let's probe with the first option:

9x - 15 = 33 => 9x = 33 + 15 = 48

=> x = 48 / 9 = 5,33, which is no in the list of options.

Now, let's probe the second option.

The other angle of the first right triangle is 90° - 33° = 57°

Then, 9x - 15 = 57

=> 9x = 57 + 15 = 72

=> x = 72 / 9 = 8

Which is the option c. 8.

So, I am sure that if you have a figure it will be compatible with that answer, else yet the procedure to find the answer is what I have used here.

Answer: option c. 8

how much apple juice does each person get if 6 people share 2 and 2/3 quarts equally

Answers

First convert 2 2/3 to an improper fraction. That comes out to 8/3. Then multiply 8/3 with the inverted fraction 1/6. It comes out to be 8/18, but most require simplification, which is 4/9 quart per person.

The fraction of apple juice shared by 6 people is A = 4/9 of the apple juice

What is a Fraction?

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.

Given data ,

Let the fraction of apple juice shared by 6 people be A

Let the total number of people be represented as n = 6 people

Now , the fraction of total amount of apple juice = 2 2/3

The fraction of total amount of apple juice T = ( 8/3 ) of apple juice

And , the equation is

A = fraction of total amount of apple juice T / total number of people n

On simplifying , we get

A = ( 8/3 ) / 6

A = ( 8/18 )

Divide by 2 on both numerator and denominator of the fraction , we get

A = 4/9 of the apple juice

Therefore , the value of A is 4/9

Hence , the fraction of apple juice is ( 4/9 ) equally

Evaluate the dot product a⃗ ⋅b⃗ of a⃗ =3i^−8j^ and b⃗ =−2i^−6j^.

Answers

The "dot product" of two vectors has several different formulas.

Since you are given the x- and y-coordinates of both vectors a and b, we can apply the formula

a dot b  = ax*bx + ay*by, where ax=x-component of vector a, by=y comp of vector b, and so on.  

So, for the problem at hand, ax * bx + ay * by becomes

3(-2) + (-8)(-6) = -6 + 48 = 42 (answer).  Note that the dot product (or "scalar product" is itself a scalar.
Final answer:

The dot product of vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^ is calculated by multiplying the corresponding components of the vectors and summing the results, giving a final dot product of 42.

Explanation:

The dot product of two vectors a and b is calculated by multiplying the corresponding components of the vectors and summing the results. So, given the vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^, the dot product can be found as follows:

a⃗ ⋅b⃗ = (a_x * b_x) + (a_y * b_y)

Therefore, substituting the known values: a⃗ ⋅b⃗ = (3 * -2) + (-8 * -6) = -6 + 48 = 42

So, the dot product a⃗ ⋅b⃗ for vectors a⃗ =3i^−8j^ and b⃗ =−2i^−6j^ is equal to 42.

First, you need to factor the polynomial.

I'll use the trial and error method.

6x^2 - 5x - 6 = 0

6 has factors
6 and 1
3 and 2

I'll try 3 and 2 first.

(3x     )(2x      ) = 0

Now we need to factor -6.
-6 factors into
-1, 6
-6, 1
-2, 3
-3, 2

Now we need to see if one of these pairs of factors placed correclty will factor the trinomial.

(3x + 2)(2x - 3) = 0

That did it.

Now we use the zero factor property.

3x + 2 = 0 or 2x - 3 = 0

3x = -2      or 2x = 3

F=J+Jrt solve following formula for t

Answers

F=j+jrt
F-j=jrt
t=(F-j)/jr
Final answer:

To solve the formula F=J+Jrt for 't', first, subtract 'J' from both sides to get F-J=Jrt. Then, divide both sides by 'Jr', for the final equation for 't' = (F-J)/Jr.

Explanation:

This physics-related mathematics question is asking you to solve the given formula F=J+Jrt for 't'. To isolate 't', we first want to eliminate 'J' from the right side. We do this by subtracting 'J' from both sides of the equation. This gives us F-J=Jrt.

Then, we divide both sides by 'Jr'. When we do this, we are left with t=(F-J)/Jr as the rearranged formula with 't' as the subject. This results in 't' being isolated in the equation, which answers the student's question.

The reference angle is simply the acute angle between the terminal side and the x-axis

The terminal angles in the four quadrants are

[tex]\bar \theta = \theta[/tex].[tex]\bar \theta = \pi - \theta[/tex].[tex]\bar \theta = \theta - \pi[/tex].[tex]\bar \theta = 2\pi - \theta[/tex]

The given parameters are:

[tex]\theta \to[/tex] reference angle

[tex]\bar \theta \to[/tex] terminal angle

(a) If the reference angle is in the first quadrant

In the first quadrant, the x-axis is at [tex]0\ rad[/tex]

So, the terminal angle is:

[tex]\bar \theta = \theta - 0[/tex]

[tex]\bar \theta = \theta[/tex]

(b) If the reference angle is in the second quadrant

In the second quadrant, the x-axis is at [tex]\pi \ rad[/tex],

While the reference angle is between [tex]\frac{\pi}{2}[/tex] and [tex]\pi \ rad[/tex]

It means that, we have to subtract the reference angle from the x-axis

So, the terminal angle is:

[tex]\bar \theta = \pi - \theta[/tex]

(c) If the reference angle is in the third quadrant

Here, the x-axis is still at [tex]\pi \ rad[/tex],

But the reference angle is between [tex]\pi \ rad[/tex] and [tex]\frac{3}{2}\pi[/tex]

It means that, we have to subtract the x-axis from the reference angle.

So, the terminal angle is:

[tex]\bar \theta = \theta - \pi[/tex]

(d) If the reference angle is in the fourth quadrant

Here, the x-axis is at [tex]2\pi \ rad[/tex]

And the reference angle is between  [tex]\frac{3}{2}\pi[/tex] and [tex]2\pi \ rad[/tex]

It means that, we have to subtract the reference angle from the x-axis.

So, the terminal angle is:

[tex]\bar \theta = 2\pi - \theta[/tex]

Answers

medical expenses are deducted on schedule A - which is required to be over 7.5% of AGI

Answer:

He will be able to deduct his medical expenses by $1225.

Step-by-step explanation:

If his medical expenses are over 7.5% of his AGI he can reduce it to 7.5%.

His AGI was $89,000. How much is 7.5% of that?

0.075*89000 = $6675.

His expenses are over 7.5%, so yes, he can reduce.

He can reduce from $7900 to $6675, so 7900 - 6675 = $1225

Subtract 45 on both sides,

⇒ 45 + 5/6x - 45 = 50 - 45

⇒ 5/6x = 5

Multiply by 6 on both sides,
