Answer:

C.) 5 kilograms

Step-by-step explanation:

1000 grams = 1 kilogram

To convert grams to kilograms we divide by 1000

5000g divided by 1000 kg = 5kg

May I Please Have Brainliest I'm trying to achieve a new rank

5,000 grams is equal to 5,000/1000 = 5 kilograms. The correct option is C

A unit of measurement used to describe mass or weight is the kilogram (kg). It is widely used all over the world to measure an object's weight because it is the International System of Units' (SI) fundamental unit of mass.

To convert grams to kilograms, you divide the number of grams by 1000 since there are 1000 grams in one kilogram.

So, 5,000 grams is equal to 5,000/1000 = 5 kilograms.

Therefore, the correct option is C. 5 kilograms.

Answer:

28 yards

Step-by-step explanation:

Perimeter=2(L)+2(W)

94=2(L)+2(19)

94=2(L)+38

-38       -38

56=2(L)

÷2  ÷2

28=L

Answer:

f(x)=-|x|+19

Step-by-step explanation:

so shifted 19 units up means

abosolute value of x + 19

and reflected in the x axis means that you have to put the - before the abosolute value.

so -|x|+19

Step-by-step explanation:

L = W+9

area = LW = 36

(W+9)W = 36

W²+9W-36 = 0

W = -12, 3

-12 is an extraneous solution, so W = 3 inches

L = W+9 = 12 inches

The events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

The probability is defined as the chances of happening any event. Mutually exclusive events are those in which the one event is independent of the other event.

The condition for the mutually exclusive event will be:

[tex]P(A|B)=\dfrac{P(A) \ and P(B)}{P(A)}=P(A)[/tex]

We have the data

red,    0.28

black,  0.30

white,  0.22

other   0.20

Here we will check the mutually exclusive event:-

(1)The events red and black

[tex]P(R|B)=\dfrac{P(R\ and\ B)}{P(B)}[/tex]

[tex]P(R|B)=\dfrac{0.28\times 0.30}{0.30}=0.28 =P(R)[/tex]

Hence the event is exclusive.

(2)The events white and other

[tex]P(W|O)=\dfrac{P(W\ and\ O)}{P(O)}=P(W)[/tex]

[tex]P(W|O)=\dfrac{ 0.22\times 0.20}{0.20}=0.22=P(W)[/tex]

Hence the event is exclusive.

(3) The events red and other

[tex]P(R|O)=\dfrac{P(R\ and\ O)}{P(O)}=P(R)[/tex]

[tex]P(R|O)=\dfrac{ 0.28\times 0.20}{0.20}=0.28=P(R)[/tex]

Hence the event is exclusive.

Hence the events ,The events red and black ,The events white and other, The events red and other are mutually exclusive.

Answer:

The lowest percentage of votes she could receive is 40%

Step-by-step explanation:

43% of students say they will vote for Alessandra, with a margin of error of 3%.

This means that between 43% - 3% = 40% and 43% + 3% = 46% of the students will vote for Alessandra.

This means that the lowest percentage of votes she could receive is 40% and the highest is 46%.

Answer:

2%

Step-by-step explanation:

Answer: 2%

Step-by-step explanation: Method 1

Express the ending population as a percentage of the starting population:  

127000 /129540= 1.02

1.02×100=  102%

Subtract the starting 100% to get the percent increase:

102%−100%= 2%

Answer: y=-2x+6

Step-by-step explanation:

The equation for slope-intercept form is : y=mx+b

----------------------------------------------------------------

First Step: find the slope

- (y2-y1)/(x2-x1)

GIven

x1=0

y1=6

x2=4

y2=-2

Solve

 (y2-y1)/(x2-x1)

=(-2-6)/(4-0)

=-8/4

=-2

Second Step: find the y-intercept

Given

y=-2x+b

Substitute one of the points into the equation

y=-2x+b

(-2)=-2(4)+b

-2=-8+b

b=6

[tex]Length = 6x^2 - 2x + 3[/tex]

Step-by-step explanation:

Given

[tex]Area = 42x^3 - 14x^2 + 21x[/tex]

[tex]Width = 7x[/tex]

Required

Determine the length of the aquarium

The area of a rectangular base is calculated as:

[tex]Area = Length * Width[/tex]

Substitute values for Area and Width

[tex]42x^3 - 14x^2 + 21x = Length * 7x[/tex]

Make Length the subject

[tex]Length = \frac{42x^3 - 14x^2 + 21x}{7x}[/tex]

Factorize the numerator

[tex]Length = \frac{7x(6x^2 - 2x + 3)}{7x}[/tex]

[tex]Length = 6x^2 - 2x + 3[/tex]

Answer:

(2,0)

Step-by-step explanation:

Since you're finding the x-intercept, logically y will have to equal 0 in order for x to be at its intercept, therefore plugging in 0 for y in your equation will give you your x-intercept.

3x -2(0) = 6

3x = 6

x = 2

So the x=int for this equation would be at the point:

(2,0)

Answer: 107 I think

Step-by-step explanation:

The average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

It is given that, Jupiter's temperature is -166, and Earth's temperature is 59.

We have to find the temperature difference between the earth and Jupiter.

In mathematics, subtraction is defined as the difference between two quantities. The application of subtraction can be used broadly in different applications to find or solve the problems such as finding differences between two quantities and many more.

The average temperature on Earth and the average temperature on Jupiter are obtained by applying the subtraction operation as,

Δt= T(earth) - T(jupiter)

Δt=59-(-166)

Δt=59+166

Δt=225 degrees

Thus, the average temperature on Earth is 225 degrees higher than the average temperature of Jupiter.
