Answer:

I don’t know about the last part but what I do know id the answer to the equation.

Answer: 1 1/3

Step-by-step explanation:

1. Remove the paranthesis

Removing the paranthesis will make it much easier to solve the equation.

We now have 4 1/6 + -2 5/6.

2. Rearrange the equation

We can’t have two symbols next to each other. We need to cross out one symbol so we can have only one. + and - = -. So let’s keep the "-" symbol.

We now have 4 1/6 - 2 5/6.

3. Solve the remaining equation

Now that we have a proper equation which we can solve, let’s do it.

We should then end up with 1 1/3.

Answer: 1 1/3

While mining Fred found a large metal bar that contained 24 ounces of nickel. Fred also determined that the bar was 80% nickel.
frutty [35]

Answer:

Not that I'm a chemistry expert but mathematically,The total weight of the bar is directly proportional to the known weight of the bar and the given percentage. I worked it out and found that the the total weight of the bar is 30 ounces. This is how I did it

Step-by-step explanation:

80:24

100:n

80(n)=100×24

A little equation and after it's solve the variable (n) will be equal to 30

The unit is added after calculations so that's how the answer is <em><u>3</u></em><em><u>0</u></em><em><u> </u></em><em><u>oun</u></em><em><u>ces</u></em>

Find the measure of each minor arc formed by a regular octagon inscribed in a circle. A. 15° B. 30° C.45° D. 60°
marin [14]
Your octagon has a central angle of 360 deg.  Since you're speaking of an octagon, which implies that the octagon is made up of eight triangles, divide 360 deg by 8 to obtain the measure of each minor arc formed.

PLATO: Type the correct answer in each box. The vector is first dilated by a factor of 2.5 and then rotated by pi/2 radians. If
yawa3891 [41]

Answer:

a = -1, b = -2.5

Step-by-step explanation:

Rule for the dilation of a vector \binom{x}{y} by a scale factor of k is,

(x, y) → (kx, ky)

BY using this rule for a vector \binom{-1}{4} by a scale factor of 2.5

\binom{-1}{4} → \binom{-2.5}{1}

Followed by the rotation by 90° Or \frac{\pi }{2} radians,

Rule for rotation of a vector by 90° is,

(x, y) → (-y, x)

By this rule vector \binom{-2.5}{1} will become,

\binom{-2.5}{1} → \binom{-1}{-2.5}

If we represent this vector by \binom{a}{b},

Then a = -1 and b = -2.5 will be the answer.
