Rewrite the following polynomial in standard form. -x^2-10+x^3

Farmers often plant crops in circular areas because one if the most efficient watering systems for crops provides water in a cir

Nesterboy [21]

Answer:

A

Step-by-step explanation: Scale Factor is defined as a ratio between the actual figure to that of the other figure.

And as it is clearly given in the question that 2 cm of length corresponds to 100 meters so the ratio comes out to be 1:50.

So the scale factor of the actual farm to the photo is A that is 1 to 50.

• What can you say about the values of 180 and 2x2x3x3x5?

kiruha [24]

Answer:

2×2×3×3×5 are the prime factors of 180

Step-by-step explanation:

If you draw a factor tree, you would find that 2x2x3x3x5 are the prime factors of 180

hope this helps :)

Under what operation are the set of integers closed? Explain your answer

torisob [31]

The set of integers is closed under addition, subtraction, and multiplication because when i add, subtract, or multiply any integers, the result is always an integer.

9) The base and the height of a rectangle are represented by the expressions below.

Nuetrik [128]

9 :

Given,
Perimeter = 88 units
Base = x + 4
Height = x - 6

= > Perimeter of Rectangle = 2( base + height )

= > 88 = 2{ ( x + 4 ) + ( x - 6 ) }

= > 88 / 2 = { x + 4 + x - 6 }

= > 44 = 2x - 2

= > 46 = 2x

= > 46 / 2 = x

= > 23 = x

Therefore,

Length of base = ( x + 4 ) units = ( 23 + 4 ) units = 27 units

Length of height = ( x - 6 ) units = ( 23 - 6 ) units = 17 units

10 :

Given,
First integer = x
Second integer = x + 2
Third Integer = x + 4

Given that the sum of all integers is 36

= > ( x ) + ( x + 2 ) + ( x + 4 ) = 36

= > x + x + 2 + x + 4 = 36

= > 3x + 6 = 36

= > 3x = 30

= > ( 3x ) ÷ ( 3 ) = ( 30 ) ÷ ( 3 )

= > x = 10

$\text{Hence, }$
Value of first integer = x = 10

The tempeture of chicken soup is 192.7 degrees F. As it cools the tempeture of the soup decreases 2.3F per minute.

IrinaK [193]

Answer:

Step-by-step explanation:

To find the answer to Part A, we can turn this into a simple equation:

192.7 - (2.3 times 25) = temperature, the missing value.

So therefore, after 25 minutes pass, the temperature is equal to

192.7 - 57.5, or:

135.2 = Answer to Part A.

Now, onto Part B. We can use another equation!

192.7 - 2.3x = 100.7

Now, we must solve the given equation, first by taking 100.7 from each side:

192.7 - 2.3x = 100.7

-100.7 -100.7

We are now left with: 92 - 2.3x = 0 - we must now add 2.3x to 2.3x and 0, giving us this:

92 = 2.3x, which is equivalent to 920 = 23x, if that is what you prefer to solve.

To give us our missing value (x), we can divide 920 by 23, giving us: x = 40. This is the answer to Part B: 40 minutes.

I hope this was really helpful! Tell me if you need any more help.
