12 boys 3 boys
------------- reduces to ------------
16 girls 4 girls

We want the simplified ratio of girls to students. There are 12+16, or 28, students to start with. We must reduce 16/28, which is the ratio of girls to students before simplification. This reduces to 4/7 (4 to 7).

We know that there are 16 girls. That is the first part of the ratio. Now, it says girls to students, which mean you have to add up the total of girls and boys together. 12+16=28. There are 28 students in total. Now, you have the ratio of 16:28. But, it says simplified...so we need to divide both sides of the ratio by a number. Let's choose 4 because 4 can go both into 16 and 28. 16/4=4. 28/4=7. So, the simplified ratio of girls to students in the classroom is 4:7.
Hope this helped!

Shtirlitz [24]

The diagram shows a lawn with the north side measuring 50 units and the west side measuring 28 units. The deck is scaled down by a factor of 1/5.

This is because the ratio of the length of the lawn to that of the deck is 1 : 5.

Can someone please help me

Answer:

See below

Step-by-step explanation:

If |x| < |y| and both are negative the x will be to the right of y on the number line. The point x is loser to the zero on the number line. We can illustrate this by supposing x = -3 and y = -6.

|x| = 3 and |y| = 6 and 3 < 6 but -3 on the number line is higher ( to the right) of -6 and closer to the zero.

|-8 1/3| = 8 1/3

|7 2/3| = 7 2/3

The absolute values of 8 1/3 > than absolute value of 7 2/3. The point 7 2/3 is closer to the zero on a number line.

The absolute value of F is greater than absolute value of E so E is closer to the zero line than F.

What are the roots of the polynomial equation x cubed minus 5 x + 5 = 2 x squared minus 5?

Dennis_Churaev [7]

Roots of the polynomial $x^3-5x+5=2x^2-5$ are $x=\sqrt{5},x=-\sqrt{5}\,\,and\,\,x=2$

Step-by-step explanation:

We need to find roots of the polynomial equation: $x^3-5x+5=2x^2-5$

Solving the polynomial to find roots:

$x^3-5x+5=2x^2-5\\Rearranging:\\x^3-5x+5-2x^2+5=0\\x^3-2x^2-5x+10=0$

Finding factors by grouping:

$(x^3-2x^2)(-5x+10)=0\\Finding\,\,common\,\,terms:\\x^2(x-2)-5(x-2)=0\\(x^2-5)(x-2)=0\\x^2-5=0\,\,and\,\,x-2=0\\x^2=5\,\,and\,\,x=2\\x=\pm \sqrt{5}\,\,and\,\,x=2$

So, roots of the polynomial $x^3-5x+5=2x^2-5$ are $x=\sqrt{5},x=-\sqrt{5}\,\,and\,\,x=2$
