Answer:

it is a decimal which is 3.28571428571

Step-by-step explanation:

i am in college

Step-by-step explanation:

[tex] \\ 9 \frac{6}{7} \div 3[/tex]

Change the mixed fraction into improper fraction.

[tex] \\ = \frac{69}{7} \div 3[/tex]

Reciprocal 3 for cross multiplication.

[tex] \\ = \frac{69}{7} \times \frac{1}{3} [/tex]

Divide 69 by 3.

[tex] \\ = \frac{ \cancel{69}}{7} \times \frac{1}{ \cancel{3}} [/tex]

[tex] \\ = \frac{23}{7} [/tex]

Divide the result into mixed fraction or decimal.

[tex] \\ = 3.285 \: \: or \: \: 3 \frac{2}{7} [/tex]

[Answer]

Answer:

Step-by-step explanation:

Solution for 468 is what percent of 486:

468:486*100 =

(468*100):486 =

46800:486 = 96.3

Now we have: 468 is what percent of 486 = 96.3

Question: 468 is what percent of 486?

Percentage solution with steps:

Step 1: We make the assumption that 486 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=486$.

Step 4: In the same vein, $x\%=468$.

Step 5: This gives us a pair of simple equations:

$100\%=486(1)$.

$x\%=468(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$frac{100%}{x%}=frac{486}{468}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$frac{x%}{100%}=\frac{468}{486}$

$Rightarrow x=96.3%$

Therefore, $468$ is $96.3%$ of $486$.

When a shape is rotated, it must be rotated through a point

The new position of point B is point A

The angle of rotation is given as:

[tex]Angle = 288^o[/tex]

The shape is a regular pentagon (with 5 sides).

The smallest angle of rotation that maps the pentagon onto itself is calculated using:

[tex]\theta = \frac{360}n[/tex]

So, we have:

[tex]\theta = \frac{360}5[/tex]

[tex]\theta = 72[/tex]

Let the number of rotations be n.

So, we have:

[tex]\theta \times n= Angle[/tex]

This gives

[tex]72 \times n= 288[/tex]

Divide both sides by 72

[tex]n= 4[/tex]

This means that the new position of B is 4 points away from B.

Point A is 4 points away from B, in clockwise direction

Hence, the new position of point B is point A

===================================

Explanation:

We multiply each coordinate of each point by the scale factor 4.5

For example, point L(1,0) moves to L ' (4.5, 0)  since 4.5*1 = 4.5

This trick only works because the origin is the center of dilation. If the center is some other point, then you'd have to translate first, dilate, then translate back again.

Answer:

Step-by-step explanation:

According to the Wrigley's Consumer Care Department, the fruit candies are produced in equal proportions— 20% of each of the five colors (green, red, orange, yellow, and purple). However, although these candies are made in equal proportions, the individual Skittles bags are filled by weight and by machines but on average I'd say 4/5 chance its a green.

Answer:

Step-by-step explanation:

FV = PMT [((1 + r)ⁿ - 1) / r]

PMT = $300

r = 0.04/12

n = 35(12) = 420

FV = $300 [((1 + (0.04/12))⁴²⁰ - 1) / (0.04/12)] = $274,119.28

I = $274,119.28 - 300(420) = $148,119.28
