Answer:

B) 120

Step-by-step explanation:

Initial problem: 90/x = 3/4

Cross multiply to get:

90*4 = 3x

360 = 3x

x = 120

Check (optional):

90/120 = 3/4

(simplify):

3/4 = 3/4 so it is correct

If you're confused about any of these steps, just let me know and I'll try to help!

Select from the matches below to correctly complete the statements. I'll give brainliest to someone with correct answer!
Aneli [31]

Answer:

<h3>The correct matches as follows :</h3>

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

3) The product of a linear monomial and a linear binomial - Quadratic binomial

Step-by-step explanation:

The correct matches as follows :

1) The product of a linear monomial and a linear monomial is a - quadratic monomial

<h3> Monomial is a linear expression having only term with degree 1 (variable)</h3>
  • For Example : Let x and y be two monomials which is linear
  • If we product the two linear monomials we get
  • x\times x=x^2 which is a quadratic monomial

2) The product of a quadratic monomial and a quadratic trinomial is a - quartic trinomial

<h3>For example : Let x^2 be the Quadratic monomial has one term with degree 2 and x^2+2x+3 be the quadratic trinomial ( has 3 terms with degree) </h3>
  • If we product the quadratic monomial and quadratic trinomial we have
  • x^2\times (x^2+2x+3)=x^2(x^2)+x^2(2x)+x^2(3)
  • =x^4+2x^3+3x^2
  • Therefore x^2(x^2+2x+3)=x^4+2x^3+3x^2 which is a quartic trinomial has degree 4 with three terms

3) The product of a linear monomial and a linear binomial - Quadratic binomial

<h3>For example : Let x be the linear monomial and x^2+5 be the linear binomial has two terms with degree 1</h3>
  • If we product the linear monomial and quadratic binomial we get
  • x\times (x+5)=x(x)+x(5)
  • =x^2+5x
  • Therefore x\times (x+5)=x^2+5x which is a quadratic binomial with degree 2

I NEED THIS NOW PLEASE!!!
Lady_Fox [76]

Answer:

We can predict that the spinner will possible land on the green or blue 8 out of 12 times, or 66% of the time.

Step-by-step explanation:

First of all, we need to calculate the percentage of the spinner that is both green and blue.

There are a total of 12 sections on the spinner.

6 out of 12 of the sections are green. 6/12 = 0.5 or a 50% change

2 out of 12 of the secions are blue. 2/12 = 0.16 or a 16% change

3 out of 12 of the sections are pink. 3/12 = 0.25 or a 25% chance

1 out of 12 sections are yellow. 1/12 = 0.08 or a 8% chance

Athough I provided the percantages for each color, all we really need is the data for the green and blue.

0.5 + 0.16 = 0.66

12 x 0.66 = 7.92 or 8 when rounded to the nearest whole number

Therefore, we can predict that the spinner will possible land on the green or blue 8 out of 12 times, or 66% of the time.

Hope this helps! Have a blessed day! :)
