Answer:

Each person would eat 83 grams of chocolate, which is equal to 0.083 kilograms.

Step-by-step explanation:

To determine how much chocolate each person will eat if 4 people divide 1/3 kilogram of chocolate, the following calculation must be made:

1/3 = 0.333

0.333 / 4 = 0.083

0.08 x 1000 = 83 grams

Therefore, each of the 4 people will eat 83 grams of chocolate.

The composite function g(f(x)) is equivalent to 10x^2 - 1

This are also referred to as function of a function. Given the following functions;

f(x) = 2x^2 - 5

g(x) = 5x + 7

In order to determine the composite function g(f(x))

g(f(x)) = g(2x^2 - 5)

Replace x with 2x^2 - 5 in g(x) to have;

g(f(x)) = 5(2x^2 - 5) + 7

g(f(x)) = 10x^2 - 18

Hence the composite function g(f(x)) is equivalent to 10x^2 - 1

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

[tex]Karina = 9 * 1\ unit^2[/tex]

[tex]Karina = 9\ unit^2[/tex]

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

[tex]Perry = 18 * 1\ unit^2[/tex]

[tex]Perry = 18\ unit^2[/tex]

Comparing both areas, we can conclude that Perry's claim is correct while Karina is incorrect

Answer: 27

Step-by-step explanation:

-21 to 6= 27

The difference between the numbers -21 and 6 is 27.

A number line in elementary mathematics is a representation of a graduated straight line that serves as an abstraction for real numbers, represented by the symbol R." It is assumed that every point on a number line corresponds to a real number and that every real number corresponds to a point.

Given that the two numbers are -21 and 6. The distance between the two numbers will be calculated as,

Distance = 6 - ( -21 )

Distance = 6 + 21

Distance = 27

Hence, the difference is 27.

Answer:

x = 6

∠B = 126

Step-by-step explanation:

∠A = ∠B

where

∠A = 8x + 78°

∠B = 2x + 114°

8x + 78°  = 2x + 114°    

8x - 2x = 114 - 78

6x = 36

x = 36/6

x = 6

plugin x into  ∠B = 2x + 114°

∠B = 2x + 114°

∠B = 2(6) + 114°

∠B = 126

Answer:

x = 6

∠B = 126

-18.75 is a rational number

Rational numbers are numbers that can be expressed as the fractions of two integers

That is, R is a rational number if it can be expression as:

R  =  p/q

where p and q are integers

-18.75 can be expressed as -1875/100 where both -1875 and 1000 are integers.

Since -18.75 can be expressed as the fraction of two integers, it is a rational number.

Answer:

i think x=-1 and y=3. ....

Answer:

x = -1 ,  y = 3

Step-by-step explanation:

2x+5y = 13

-x+4y = 13

Decide whether to add or subtract the two equations by using Different Add Same Subtract (DASS)   or in case below as its SUBTRACT

i apply (SDSS).  

We subtract 5y as this is easier equation either positive prioritises or if both positive then easier number becomes priory.

Results to SDSS  before substituting Y if 5y etc was subtracted

2x+5y = 13             Subtract -5  

2x+5y -5y = 13 -5y  

2x= 13 - 5y             then Divide by 2

2x / 2 = 13/2 - 5y/2          Show then

x = 13 - 5y  / 2  + 4y = 13     Simplify

simplify  13 - 13y  / 2   as   y = 3  

as 13/2 = 6.5 and 2.5 +4 = 6.5

y = 3

Substitute y = 3

13-5y )3) / 2

13-5 (3)  / 2

BODMAS Brackets first Multiplying only for y substitute 5y = 5 x 3

-5 (3) = 15

13-15 = -2

-2/2 = -1
