Mr. Monrean had three sheets of stickers. He gave 20 stickers from each sheet to his students and has 12 total stickers left. Write and solve an equation to find the total number of stickers s there were originally on each sheet.

Answer:

- ( 5x + y ) ( x + 5y )

or

-5x^2 - 5y^2 - 26xy

Answer:

Step-by-step explanation:

4(x^2-2xy+y^2)-9(x^2+2xy+y^2)

4x^2-8xy+4y^2-9x^2-18xy-9y^2

-5x^2-26xy-5y^2

-5x^2-xy-25xy-5y^2

-x(5x+y)-5y(5x+y)

(-x-5y)(5x+y) or you can also remove the negative one to get

-(x+5y)(5x+y)

Answer:

y = -2x + 7

Explanation:

y = mx + b

m = slope

b = y-intercept

y = a given y coordinate

x = a corresponding x coordinate

First, we need to find the slope (m).

1) (4, -1)

2) (2/3)

m = slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{3-(-1)}{2-4}[/tex] = [tex]\frac{4}{-2}[/tex] = -2

plug in the values to the equation y = mx + b

-1 = -2(4) + b

-1 = -8 + b

7 = b

now, we can substitute in m and b into the equation y = mx + b

y = -2x + 7

Answer:

4x - 16

Step-by-step explanation:

A triangle is a three sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees

the perimeter of a triangle = sum of the side lengths

let the unknown length be represented with y

13x  - 21 = 4x + 3 + 5x - 8 + y

13x- 21 = 9x - 5 + y

Make y the subject of the formula

13x - 21 - 9x + 5 = y

4x - 16 = y

the side length = 4x - 16

happy to hep ya :)

Step-by-step explanation:

Answer:

you are correct do not say any other answer

Answer:

The answer is either

y=50000 x 0.8^x

or

y=50000(20%)^x but this just seems wrong

Step-by-step explanation:

Step-by-step explanation:

BC^2 + DC^2 = AC^2

6^2 + 4^2 =AC^2

36 + 16 = AC^2

52=AC^2

√52=AC

AC=7.2111

Answer:

Part a) to find the maximum height of the snowball, you have to differentiate the function. Therefore you get ----> dh/dt= -32x-8 . Now equate this to zero and solve for x. x= (-1)/4 now sub this value in to find h(x) [note: i'm talking about the original function] . I got h max = h((-1)/4) = 9 which is the max height.

Step-by-step explanation:

I'm not too sure about the other questions. Sorry

Answer:

x = 114 ur welcome

Step-by-step explanation:

Answer:

x = 114

Step-by-step explanation:

Given

[tex]\frac{x+18}{4}[/tex] = 33 ( multiply both sides by 4 to clear the fraction )

x + 18 = 132 ( subtract 18 from both sides )

x = 114

2176

Step-by-step explanation:

2+2=4 68(8)= 544

4× 68×8= 2176

Step-by-step explanation:

Hey!

==================================================================

We always follow these rules when we are Multiplying and Dividing numbers with Scientific Notation.

1. If the numbers are not in scientific notation, convert them.

2. Regroup the numbers using the commutative and associative properties of exponents.

3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.

             -Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾  to multiply the bases.

4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.

5. Join the new coefficient to the new power of 10 to get the answer.

--------------------------------------------------------------------------------------------------------------

Let's start!

Our equation:

                                  (5.2 × 10⁶)(7 × 10⁸)

--------------------------------------------------------------------------------------------------------------

1. If the numbers are not in scientific notation, convert them.

They are in scientific notation, so we go on to step 2.

2. Regroup the numbers using the commutative and associative properties of exponents.

(5.2 × 7)(10⁶ × 10⁸)

3. Now multiply the two numbers written in scientific notation, you work out the coefficients and the exponents separately.

             -Use the product rule; aⁿ × aᵇ = a⁽ⁿ⁺ᵇ⁾  to multiply the bases.

5.2 × 7 = 36.4

10⁶ × 10⁸= 10⁽⁶⁺⁸⁾ = 10¹⁴

4. If the product of the coefficients is greater than 9, convert it to scientific notation and multiply by the new power of 10.

36.4 = 3.64 × 10¹

5. Join the new coefficient to the new power of 10 to get the answer.

3.64 × 10¹ × 10¹⁴

3.64 × 10⁽¹⁺¹⁴⁾ = 3.64 × 10¹⁵

==================================================================

3.64 × 10¹⁵

Answer:

closest option B (50.24)

Step-by-step explanation:

A=πr²

= π×4×4

=π×16

=50.265m²

Area:

50.24 m^2

Explanation:

The formula for the area of a circle is A = πr²,

where:

Diagram:

[tex]\setlength{\unitlength}{1cm}\begin{picture}(0,0)\thicklines\qbezier(2.3,0)(2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,2.121)(0,2.3)\qbezier(-2.3,0)(-2.121,-2.121)(0,-2.3)\qbezier(2.3,0)(2.121,-2.121)(-0,-2.3)\put(0,0){\line(1,0){2.3}}\put(0.5,0.3){\bf\large 4\ m}\end{picture}[/tex]

Plug in the data. I'll use 3.14 for pi.

[tex]\bf{A=\pi \times4^2}\\\bf{A=3.14\times16}\\\bf{A=50.24\:m^2}[/tex]

Hence, area = 50.24 m^2
