Answer:

When you remove a set positive counter the number decrease

When you remove a set of negative counter the number increases

Step-by-step explanation:

When you remove a set positive counter the number decrease it's like subtracting like adding a negative counter (-)

Example: 10 - 5 = 5

When you remove a set of negative counter the number increases it's like adding a positive counter (+)

Example: -10 - (-5) = -5

Urgent!! I will give brainiest to right answer

Over [174]

Answer:

1) option c

2) option d

3) option a

4) option a

5) option c

Step-by-step explanation:

1. Given that in ΔRST, ∠R=63°, ∠T=90° and so ∠S=27°

Also, cosec=hyotenuse/opposite side

Given RS=23 and ST=10.4

So, cosec27=RS/RT=23/RT

sec=hypotenuse/adjacent side

sec27=RS/ST=23/10.4

And cot=adjacent/opposite side

So, cot63=RT/ST=RT/10.4

2. formula:- sinθ=opposite side/hypotenuse

cosecθ=hypotenuse/opposite side

∴ sinθ *cosecθ = (opposite side/hypotenuse) * (hypotenuse/opposite side) = 1

3. Formula :- tan(360-θ) = -tanθ

∴ tan(300) = tan(360-60) = -tan30°

tan30° = √3

∴tan300° = -√3

5. sinθ= opposite side/hypotenuse

cosecθ = hypotenuse/opposite side

∴ cosecθ = 1/sinθ

Given sinθ = 0.3090

∴ cosecθ = 1/0.3090 = 3.2362

Show 2 ways 4 people 6-segment chewy fruit worm in each case, how many segments does each person get?

finlep [7]

Question:

Show 2 ways that four people can share a 6-segment chewy fruit worm.

In each case how many segments does each person get ?

Answer:

a. $Each\ Person = 1.5\ segments$

b. $Each\ person = 3\ segments$

Step-by-step explanation:

Given

$Segments = 6$

$People = 4$

Method 1: Simply divide the number of segments by the number of people.

$Each\ Person = \frac{Segments}{People}$

$Each\ Person = \frac{6}{4}$

$Each\ Person = 1.5$

Method 2:

Start by taking LCM of 4 and 6

$4 = 2*2$

$6 = 2 * 3$

$LCM = 2 * 2 * 3$

$LCM = 12$

This means that you divide the chewy fruit into 12 segments. This is done by cutting each segment in half.

Each person gets:

$Each\ person = \frac{Segments}{People}$

$Each\ person = \frac{12}{4}$

$Each\ person = 3$

So, when the fruit is further divided to 12, each person gets 3 segments of the division.
