The number of emergency kits that Neil packed in total for the 150 bottles is gotten as; k = 50 kits.

We are told that Neil puts 3 water bottles into each emergency kit packed.

Now, let the number of emergency kits be k.

Thus;

3k = 150

Division property of equality, we have;

3k/3 = 150/3

k = 50

Thus, the number of emergency kits that Neil packed is gotten as k = 50 kits.

Answer:

-21x² + 8x + 2

Step-by-step explanation:

Addition of two polynomials:

Like terms have same variable with same power. Combine like terms.

(-16x² & -5x² are like terms ;  10x and (-2x) are like terms ;  (1 and 1 are constants)

-16x² + 10x + 1 + (-5x² - 2x + 1) = -16x² + 10x + 1 -5x² - 2x + 1

                                                = -16x² - 5x² + 10x - 2x + 1 + 1

                                                 = -21x² + 8x + 2

Answer:

Of the ones listed, in the way they are written, the answers are x²y – 3x and 6y² – y.

Explanation:

A monomial is a constant, a variable, or the product of constants and variables.  A binomial is the sum or difference of two monomials.  

The first option, xy, is a monomial.  There is only one, so it is not a binomial.

The second one, x²y-3x, is the difference of two monomials; this means it is a binomial.

The third one, 6y²-y, is the difference of two monomials; this means it is a binomial.  

The last one, y²+4xy-x², is the sum and/or difference of at least three monomials (there is a plus at the end that makes me think there is more to it).  This means it is a trinomial, not a binomial.

Answer: B, C, and E.

Step-by-step explanation:

Since all three show the characteristics found in a binomial then these three are your answers. Plus I just did it on Edge.

J. x = 1

Step-by-step explanation:

Write an equation based on the image of the scales.

3x + 6 = 9

Subtract 6.

3x = 3

Divide by 3.

x = 1

If you haven't learned to solve equations yet, the same thought process can be used with the scale image. The scales are balanced. To keep them balanced, remove 6 of the pieces marked "1" from BOTH sides of the scale. Then the scale will have three x's on one side and three "1"'s on the other side. So each x has to be one "1".

Answer:

 x = 5, x = 1

Step-by-step explanation:

The quadratic equation 0 = 4(x - 3)2 - 16.

Using binomial theorem, (a - b)2 = a2 - 2ab + b2 to expand (x - 3)2.

0 = 4(x2 - 6x + 9 ) - 16.

Using distributive property to multiply 4 by x2 - 6x + 9.

0 = 4x2 - 24x + 36 - 16.

Subtract 16 from 36 to get 20.

0 = 4x2 - 24x + 20.

4x2 - 24x + 20 = 0.

Divide both sides by 4.

x2 - 6x + 5 = 0.

To solve the equation, factor and rewrite as x2 + ax + bx + 5

a + b = -6, ab = 1(5) = 5.

a = -5, b = -1.

Rewriting x2 - 6x + 5 as

(x2 - 5x) + (-x + 5)

Factor x in the first and -1 in the second group.

x(x - 5) - (x - 5)

Factor out common term

(x - 5)(x - 1)

By solving the above, we get

x = 5, x = 1

Based on the annual percentage increase and the actual amount, the wage rate per hour at Phoebe's job is $15 per hour.

The company gives an increase of 5% on the hourly wage per hour and this amount comes out to be $0.75.

The wage rate per hour is therefore:

= Actual increase amount / Percentage increase

Solving gives:

= 0.75 / 5%
= $15 per hour

Answer:

Z = 63º

Step-by-step explanation:

X = 180 - 61 - 31 = 88º Angles in a triangle add to 180º

Y = 180 - X = 180 - 88 = 92º Angles in a straight line add to 180º

Z = 180 - 25 - Y = 180 - 25 - 92 = 63º Angles in a triangle add to 180º

Step-by-step explanation:

It is the corner or a point where line segments meet.

Hi!

Your answer is C.

The vertex is the point where two different rays meet, forming an angle.

It can also simply be the point where 2 straight lines simply meet.

Option A is NOT correct because a vertex is not angle, it is a part of an angle.

Option B is NOT correct because, if there's only one segment, we cannot form a vertex.

If the bottom of the big rectangle is 9 then the top should also be 9. We now have 22m.

The left side of the small rectangle is 2m then so should the right be also 2m. We have 4m.

The top is 3m so the bottom should also be 3m we now have 10m

[tex]\textsf{\sf(a)} \quad y=-\dfrac54x+\dfrac{205}{2}[/tex]

(b)  $46.25

Step-by-step explanation:

When adding a line of best fit, ensure that the number of points above and below the line is about equal.

See attachment for line of best fit.

From inspection of the graph, two points on the line are (10, 90) and (50, 40).  Therefore,

[tex]\textsf{let}\:(x_1,y_1)=(10,90)[/tex]

[tex]\textsf{let}\:(x_2,y_2)=(50,40)[/tex]

Calculating the slope of the line:

[tex]\textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{40-90}{50-10}=-\dfrac54[/tex]

Using the point-slope form of linear equation:  [tex]y-y_1=m(x-x_1)[/tex]

(where m is the slope and (x₁, y₁) is a point on the line)

[tex]\implies y-90=-\dfrac54(x-10)[/tex]

[tex]\implies y-90=-\dfrac54x+\dfrac{25}{2}[/tex]

[tex]\implies y=-\dfrac54x+\dfrac{205}{2}[/tex]

(where x is the average monthly temperature in °F and y is the monthly heating costs in dollars)

Substitute x = 45 into the equation found in part (a):

[tex]\implies -\dfrac54(45)+\dfrac{205}{2}=46.25[/tex]

Therefore, the monthly heating cost for a month with an average temperature of 45 °F is approximately $46.25

The magnitude of this earthquake using the Richter scale is approximately 3.3 (rounded to the nearest tenth).

To calculate the magnitude of the earthquake using the Richter scale, we can use the formula

R = log(A/A₀),

where

A is the amplitude of the earthquake wave, and

A₀ is the amplitude of the standard wave.

If the earthquake wave's amplitude is 1800 times as great as the smallest detectable wave, this means A/A₀ = 1800.

Therefore, the magnitude of the earthquake (R) would be:

R = log(1800)

Let's calculate it:

R ≈ log₁₀(1800) ≈ 3.255

So, if we round this to the nearest tenth, the earthquake's magnitude on the Richter scale would be approximately 3.3.
