Order the amount of rain from least to greatest
babymother [125]

Answer:

1/5, 1/2, 3/4

Step-by-step explanation:

I just now this already from experience, but you could covert all of the fractions into a common denominator. For example use 20.

1/5 = 4/20

1/2 = 10/20

3/4 = 15/20

Then you just need to look at the numerators which 4,10,15 would be the order. And then make sure to convert to the original fractions making the final order be 1/5, 1/2, 3/4.

A flowerbed is to be 3m longer than its width.the flowerbed will have an area of 70m²​
melomori [17]
ANSWER
Yes, it is a quadratic equation which is x² + 3x - 70 = 0

SOLUTION

Area = Length × Width
Let x be the Length, L = x
Length is 3 cm longer than its width, thus, W = x + 3
The Area is equal to 70m², thus, A = 70m²

In Mathematical representation,
A = L × W
70 = (x)(x + 3)
70 = x(x) + x(3)
70 = x² + 3x
0 = x² + 3x - 70

What binomial do you have to add to the polynomial 2x^2+3y^2-5xy+1 to get the following. A polynomial that does not contain x
kiruha [24]

The Binomial -2x^{2} + 5xy have to be add to the polynomial 2x^{2} +3y^{2} -5xy+1 to get polynomial that does not contain x.

<h3>What is binomial?</h3>

A mathematical expression consisting of two terms connected by a plus sign or minus sign.

Example: x + 2 is a binomial, where x and 2 are two separate terms.

<h3>What is polynomial?</h3>

A polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer

According to question

polynomial 2x^{2} +3y^{2} -5xy+1

When added to binomial -2x^{2} + 5xy

= 3y^{2} +1  (as 2x^{2}  -5xy got cancelled )

and this polynomial does not contain x

Hence, Binomial -2x^{2} + 5xy have to be add to polynomial 2x^{2} +3y^{2} -5xy+1 to get polynomial that does not contain x.
