The average winter temperature at the South Pole is -49 degrees Celsius. The coldest temperature recorded in Antarctica was 40.6 degrees Celsius colder than the average winter temperature at the South Pole. What was the coldest recorded temperature in Antarctica?

Answers

Answer:

The coldest temperature at Antarctica is -89.6 degrees celsius

Step-by-step explanation:

Here, we are interested in calculating the coldest temperature in Antarctica.

In the question, we are simply told that the coldest Antarctica temperature was 40.6 colder than the average winter temperature at the south pole.

The average winter temperature at south pole = -49 degree celsius

The coldest temperature is thus -49-40.6 = -89.6 degrees celsius

Step-by-step explanation:

Evaluate g(5), then use the value obtained to evaluate f(x) , that is

g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then

f(30) = 3(30) + 2 = 90 + 2 = 92

Answer:

they won 52 games

they lost 19 games

the equation is  2x + 33= 71

Step-by-step explanation:

they played 71 games in total

say the amount of games they won is y

say the amount of games they lost is x

using the variables, you can form this equation:

y + x = 71

you also know that they won 33 more games then they lost.

so, y = x + 33

now, you can substitute y for x + 33 in the original equation

x + x + 33 = 71

combine like terms

2x + 33 = 71

subtract 33 from both sides of the equation

2x + 33 - 33 = 71 - 33

2x = 71 - 33

2x = 38

divide both sides of the equation by 2

2x/2 = 38/2

x = 38/2

x = 19

they lost 19 games.

now substitute 19 for x in the equation

y = x + 33

y = 19 + 33

y = 52

they won 52 games

Find the distance between the two points in simplest radical form.
(0, –4) and (-3,-1)

Answers

Answer:

3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (0, - 4) and (x₂, y₂ ) = (- 3, - 1)

d = [tex]\sqrt{(-3-0)^2+(-1+4)^2}[/tex]

   = [tex]\sqrt{(-3)^2+3^2}[/tex]

   = [tex]\sqrt{9+9}[/tex]

   = [tex]\sqrt{18}[/tex]

   = [tex]\sqrt{9(2)}[/tex]

    = [tex]\sqrt{9}[/tex] × [tex]\sqrt{2}[/tex] = 3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

Hey there!

Given;

The points are;(0,-4) and (-3,-1).

Use formula for distance between the two points.

[tex]d = \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } [/tex]

Put all values.

[tex]d = \sqrt{( { - 3 - 0)}^{2} + ( { - 1 + 4)}^{2} } [/tex]

Simplify to get answer.

[tex]d = \sqrt{9 + 9} [/tex]

[tex]d = \sqrt{18} [/tex]

[tex]d = 3 \sqrt{2} [/tex]

Therefore, the distance is 3√(2) units or 4.24 units.

In class of 60 boys, there are 45 boys who play card and 30 boys who play carom. How many play both games​

Answers

Answer:

the answer is 40 boys

Step-by-step explanation:

Let's say there are x boys who play both cards and carrom.

We setup up an equation that involved all information given and x.

Boys who only play cards = 45-x

Boys who only play carrom = 20-x

Boys who play both = x

Add there together and you should get 60, which is the total number of students in the class.

(45-x)+(20-x)+x=60

65-x=60

x=5

Boys who only play cards=45-x=45–5=40

Answer:   -26

=================================================

Explanation:

Replace every x with -3

Then use the order of operations (PEMDAS) to simplify

y = -2x^2 + x - 5

y = -2(-3)^2 + (-3) - 5 ... x replaced with -3

y = -2(9) - 3 - 5

y = -18 - 3 - 5

y = -21 - 5

y = -26

Answer:

-26

Step-by-step explanation:

1. plug in -3 for all x's

  -2(-3)^2 + (-3) -5

2. combine like terms

  -2(-3)^2 - 8

3. pEmdas. deal with exponent first (remember: only affect the 3, since it's in parentheses! also when you square a negative number, it becomes positive!)

  -2(9) - 8

4. peMdas. multiply -2 and 9 next.

  -18 - 8

5. pemdaS. subtract 8 from -18.

  -18 - 8 = -26
