Answer:

x = 11

Step-by-step explanation:

180°( n - 2 ) ÷ n

~~~~~~~~~~

( 7x + 31)° = 180°( 5 - 2 ) ÷ 5

7x + 31 = 108

7x = 77

x = 11

Answer:

y = 3x + 14

Step-by-step explanation:

Slope: 3

y-intercept: 2 - (3)(-4) = 2 + 12 = 14

If the mean score is 55% and the s.d. is 15%, then a test score of at least

55% + 1.5 × 15% = 77.5%

falls in the A range.

The next cutoff score is 0.5 s.d. from the mean, which is

55% + 0.5 × 15% = 62.5%

so any test score between 62.5% and 77.5% is in the B range.

The next cutoff is

55% - 0.5 × 15% = 47.5%

so a score between 47.5% and 62.5% gets a C.

The lower limit of the next range is

55% - 1.5 × 15% = 32.5%

so 32.5% - 47.5% gets a D.

Anything lower than 32.5% is an F.

Use Pythagorean to find the distance through the field:

Difference between two options:

Answer:

It is faster to walk through the field and directly to Ah Chong's house.

The difference between the distance via the road and through the field is 26 m.

Step-by-step explanation:

The scenario can be modeled as a right triangle (see attached diagram).

⇒ Total distance = 195 + 28 = 223 m

To calculate this distance (hypotenuse of the right triangle), use Pythagoras Theorem.

Pythagoras Theorem

[tex]a^2+b^2=c^2[/tex]

where:

[tex]\implies 195^2+28^2=c^2[/tex]

[tex]\implies c^2=38025+784[/tex]

[tex]\implies c^2=38809[/tex]

[tex]\implies c=\sqrt{38809}[/tex]

[tex]\implies c=197[/tex]

Therefore, the distance for option 2 is 197 m.

Option 1 - Option 2 = 223 - 197 = 26 m

As 197 < 223, it is faster for Rahmat to walk through the field and directly to Ah Chong's house (option 2).

Step-by-step explanation:

Step-by-step explanation:

yes, in a similar way as division is a shortcut for repeated subtraction.

you do know, that you normally have to add the points win in a game, right ?

so, your score grows by 200 points each time you score.

that means

200

200

200

...

200

what do you think you do to get the total ? you add all the points.

you don't multiply them, because e.h 200×200 would be the shortcut of adding 200 for 200 times.

but you did not have 200 hits, you only got 12 hits.

so, you either do the effort of adding 200 12 times, or you simply multiply 200 by 12 (as this is the mentioned shortcut).

and you don't just add 12 to 200. that would give you only 212. and you did not earn 12 points to add. you earned 12 times 200 points to add.

that is how multiplication works and helps with additions.

Answer:

t = 5

Step-by-step explanation:

Given r varies directly as t³ then the equation relating them is

r = kt³ ← k is the constant of variation

To find k use the condition r = 54 when t = 3 , then

54 = k × 3³ = 27k ( divide both sides by 27 )

2 = k

r = 2t³ ← equation of variation

When r = 250 , then

250 = 2t³ ( divide both sides by 2 )

125 = t³ ( take cube root of both sides )

[tex]\sqrt[3]{125}[/tex] = t , that is

t = 5

Step-by-step explanation:

I think you made a mistake with the equation.

because that property, that you presented, did not exist.

but

3(x+4) = (x+4)3 exists

and it is the commutative property of multiplication (a×b = b×a).

The third side of a triangle is greater than the difference and less than the sum of the lengths of the two given sides.         6 - 4 = 2  and 6 + 4 = 10

So the third side is between 2 and 10.

Answer:  SLOPE=-170, Y-INTERCEPT = 1020

Step-by-step explanation:

Calculate the slope:  Take any two points and find the changes in x and y:

I'll use (4, 340) and (6, 0):

Change in y (the rise) is (0 - 340) = -340.

The change in x is (6-4) = 2

The slope is the rise (y) over the run (x):  -340/2 or -170.

The y-intercept is the value of y when x=0.  The f=-data provided has a value for y at x=0:  (0,1020).  So the interecpt is 1020.

Irma has a total point of -8 now.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given that, Irma is just learning to play the Happy Fairies video game.

In the game, based on the taking care of fairies, players gain and lose points.

Initial point Irma had = -5 points

Fairy fell over in the wind and she got -3 points.

Final point = -5 + -3

                 = -5 - 3

                 = -8

Hence the total points now is -8.
