Please help!! I really need it.

Answer:

The first one: if 2/3 is 12 then 1/3 is 6. 3/3 is 18. SO Jane had 18 stuffed animals  before the donation.

The second one: 25 students then 13 are men so 25-13 is 12. 12/25 as a percentage is 48%

Hope this helps!

Answer:

[tex]Section \: A. \\before \: the \: donation \ : jane \: had \: \boxed{18 \: (stuffed \: animals)} \\

Section B.\\

\boxed{the\: percentage\: of\: female\: student\: is\: \boxed{48 \%}}

[/tex]

Step-by-step explanation:

[tex]Section A.\\let \: the \: total \: animals \: be \to \: t_{a} \\ let \: the \: donated\: animals \: be \to \: d_{a} \\ then \to \\ if \: d_{a} = \frac{2}{3} (t_{a} ) : we \: can \: find \: t_{a} \: by \to \\ 12 = \frac{2}{3} (t_{a} ) \\ 2(t_{a} )= 12 \times 3 \\ t_{a} = \frac{36}{2} \\ \boxed{ t_{a} = 18.}

\\ \\

Section B.\\

let \: the \: total \: number\: of \: students\: be \: be \to \: t_{s} \\ let \: the \: number\: of \: male\: student\: be \: be \to \: m_{s} \\ then \to \\ if \: t_{s} = m_{s} +1 3 \: then \\

m_{s} = t_{s} -13\\

m_{s} = 25-13 \\

m_{s} =12 \\

hence \: percentage \: of \: girls \: is = \frac{12}{25} \times 100 \\

the \: percentage\: is \to \boxed{m_{s} = 48\%}

Answer:

Number of protons

Step-by-step explanation:

The atomic number represents the number of protons that are in the nucleus. This says what chemical properties something has and where it is located on the periodic table.

Best of Luck!

I think the answer is 2.

Answer:

1597.3333333333

Step-by-step explanation:

= 17-176+19+14+1723+3/9.

= 17-176+19+14+1723+0.33333333333333

= -159+19+14+1723+0.33333333333333

= -140+14+1723+0.33333333333333

= -126+1723+0.33333333333333

= 1597+0.33333333333333

= 1597.3333333333

Answer: the answer to 1 is 2

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

5(x-4) = 3x + 4

5x-20 = 3x + 4

5x-3x-20= 4

2x=4 +20

2x=24

x=12

check answer by inserting 12 for x into original  equation.

5(12-4) = 3(12) +4

5(8) = 36 +4

40 = 40

The question is not complete. I have assumed you want to calculate the length of each piece.

Answer:

The shortest piece is 4 inches long

The longest piece is 8 inches long

Step-by-step explanation:

Equations

One piece of tubing is two times the other.

Let's call

x=the shortest piece of tubing

2x=the longest piece of tubing

The total length of the piece of tubing is 12 inches, thus:

x + 2x = 12

Simplifying:

3x = 12

Dividing by 3:

x = 12 / 3 = 4

x=4, and 2x=8, thus:

The shortest piece is 4 inches long

The longest piece is 8 inches long

Answer: 3,250

Step-by-step explanation:

Answer:

Less than -4

Step-by-step explanation:

negative numbers multiplied by negative numbers= positive numbers

so less than -4 makes the sum greater

Answer:

p<4

Step-by-step explanation:

REASON: The four has an open circle and it's four greater than the number/variable

Answer:

5x⁴ + 7x or x(5x³ + 7 )

Step-by-step explanation:

Given expression:

        5x⁴ - 7(-x )

To simplify this expression, we have to follow the order of operation PEMDAS;

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction

  5x⁴ - 7(-x ) = 5x⁴ + 7x

               Since x is common to both terms;

                = x(5x³ + 7 )

So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )

Answer:

Degree of the polynomial function = 5

Step-by-step explanation:

Since, the given graph of a polynomial has the x-intercepts at x = -2, -0.5, 0.5, 1.5, 3

Therefore, the equation of the polynomials with zero roots will be,

y = (x + 2)(x + 0.5)(x - 0.5)(x - 1.5)(x - 3)

When we solve this expression highest degree of the variable x will be 5.

Therefore, the possible degree of the polynomial function = 5

i was going to screenshot the answer bc i got it right but its

"odd 5 degrees or greater" :)

Answer:

yes

Step-by-step explanation:Because if you  divide 8/18 by 2 you get 4/9 so yes

Answer:

Yes.

Step-by-step explanation:

4/9 IS equivalent to 8/18. If you simplify 8/18 it is equal to 4/9, therefore they have the same value.

Answer:

9

Step-by-step explanation:

so you write the expression 2.75+1.25x= ?

If we subsitute the X for 5(miles) the we'll have the expression 2.75+1.25(5)= ?

and if you simplify that you will get 9.

Answer:

2/5 or .4

Step-by-step explanation:

basically look at the points where the line meets the graph. two points would be 0,20 and 50,40. then count the amount that it changes vertically and then horizontally. +20vertical +50 horizonal giving the slope 20/50. this can then be simplified to 2/5 or the equivalent number .4

Answer:

If I remember correctly, the slope would be 2/5.

Answer:

5.02

Step-by-step explanation:

Answer:

You cannot simplify because you cannot square root a negative.

Answer:

Yes

Step-by-step explanation:

I mean it can if you use () and stuff

Answer:

yes, technically

Step-by-step explanation:

so you can do somthing like -5+7 and get 2
