Answer:

  7.8 cm

Step-by-step explanation:

The relevant formula is ...

  A = 1/2aP . . . . where a is the apothem, and P is the perimeter.

For a regular 12-gon the perimeter is 12 times the side length, so we have ...

  P = 12s = 12(4.2 cm) = 50.4 cm

Then the apothem is found from ...

  197 cm² = (1/2)a·(50.4 cm)

  a = 197/25.2 cm ≈ 7.81 cm

The apothem is about 7.8 cm.

__

Additional comment

A regular 12-gon with a side length of 4.2 cm will have an area of about 197.500 cm². The apothem will be about 7.837 cm. The area of a regular n-gon can be calculated from the side length as ...

  A = ns²/(4·tan(180°/n))

Similarly, the apothem will be ...

  a = s/(2·tan(180°/n))

Answer:

for (−4/5)x + 3/10 < 8/10:  solution is x > -5/8

for −4/(5x) + 3/10 < 8/10: solution is x > -8/5

Step-by-step explanation:

I'm not exactly sure if you mean -4 divided by 5x or (-4/5)x, so I've done both! :)

[tex]-\frac{4}{5}x+ \frac{3}{10} < \frac{8}{10}[/tex]

subtract 3/10 from both sides:  [tex]-\frac{4}{5}x < \frac{5}{10}[/tex]

Divide both sides by 4/5:  [tex]-x < \frac{5}{8}[/tex]

Divide both sides by -1 (reverse sign):  [tex]x > -\frac{5}{8}[/tex]

[tex]-\frac{4}{5x}+ \frac{3}{10} < \frac{8}{10}[/tex]

subtract 3/10 from both sides:  [tex]-\frac{4}{5x} < \frac{5}{10}[/tex]

Multiply both sides by 5x:  [tex]-4 < \frac{5}{2}x[/tex]

Divide both sides by 5/2:  [tex]x>- \frac{8}{5}[/tex]

[tex]\\ \tt\longmapsto \dfrac{-4}{5}x+\dfrac{3}{10}<\dfrac{8}{10}[/tex]

[tex]\\ \tt\longmapsto \dfrac{-4}{5}x<\dfrac{5}{10}[/tex]

[tex]\\ \tt\longmapsto -4/5x<1/2[/tex]

Answer:

x = 52°

y = 128°

Step-by-step explanation:

This is an isosceles trapezoid as the legs are the same length (denoted by the double dashes).

For an isosceles trapezoid, the sets of angles adjoined by parallel lines are equal.  Therefore, for this trapezoid, y = 128 and the two remaining angles are both x.

The interior angles of a trapezoid = 360°

Therefore, x + x + 128 + y = 360

Since we know y = 128:

2x + 128 + 128 = 360

⇒ 2x = 104

⇒ x = 104 ÷ 2 = 52

Answer:

38 in²

Step-by-step explanation:

5 faces:

front: area = 2*6/2 = 6

back = front = 6

left = 3 * 2 = 6

right = 4*2 = 8

bottom = 6*2 = 12

total = 6 + 6 + 6 + 8 + 12 = 38 in²

Answer:

x=29

Step-by-step explanation:

We know y is 16. We can write 16 instead of y in the equation.

y=x-13

16=x-13

Now we can add 13 to both sides of the equation.

16+13=x-13+13

29=x

x is equal to 29.

Answer:

x = 29

Step-by-step explanation:

since y = 16

16 = x -13

Add 13 to both sides of the equation

16 + 13=x-13+13

Simplify

x = 29

Answer:

Step-by-step explanation:

First of all, you add 1/3 and 4/5, so you get:

To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get:

Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:

That's the sum of 1/3 + 4/5.

Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:

In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:

Since 119 and 15 don't have a common factor, so they can't be simplified.

So, the answer is 119/15.

The factorization of the trinomial is A = 3 ( x - 2 ) ( x - 5 )

Brackets should be expanded in the following ways to factorize an expression

For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket

For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.

Given data ,

Let the expression be represented as A

Now , the value of A is

A = 3x² - 21x + 30   be equation (1)

On simplifying , we get

Taking 3 as the common factor of the expression , we get

A = 3 ( x² - 7x + 10 )

A = 3 ( x² - 2x - 5x + 10 )

On factorizing , we get

A = 3 ( x - 2 ) ( x - 5 )

Hence , the expression is A = 3 ( x - 2 ) ( x - 5 )

Answer:

The unlimited mileage plan would save money for Lia from 410 miles onwards.

Step-by-step explanation:

Since Lia can rent a van for either $ 90 per day with unlimited mileage or $ 50 per day with 250 free miles and an extra 25 ¢ for each mile over 250, to determine for what number of miles traveled in one day would the unlimited mileage plan save Lia money, the following calculation must be performed:

90.25 - 50 = 40.25

40.25 / 0.25 = 161

161 + 250 = 411

Therefore, the unlimited mileage plan would save money for Lia from 410 miles onwards.

The solution is, the correct probability distribution is 1/16.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

Given that,  

spinner contains four sections: red, blue, green, and yellow. Joaquin spins the spinner twice. The set of outcomes is given as

S = {RB, RG, RY, RR, BR, BG, BY, BB, GR, GB, GY, GG, YR, YB, YG, YY}.

If the random variable is “yellow (Y),” let us first find the values that Y can take.

From the sample space given above, we find that Y can take only 3 values 0,1,2

In the sample space of 16 entries, Y occurs 0 times in 9 times

1 time in 6 times and 2 times 1 time

Hence probability = no of favouable outcomes/number in sample space

So

P(Y=0) = 9/16

P(Y=1) = 6/16 = 3/8

P(Y=2) = 1/16

Hence, The solution is, the correct probability distribution is 1/16.

Answer:

22 stickers in each box

Step-by-step explanation:

Ling Ling = 587 stickers

Jia = 245 stickers

Therefore, total number of stickers = 587 + 245 = 832

if they gave 40 stickers to their cousin, then

remaining stickers = 832 - 40 = 792

If they put the remaining 792 stickers equally into 36 boxes, then

number of stickers in each box = 792 ÷ 36 = 22
