Answer: You should get 15 water bottles

Step-by-step explanation: You need at least 8 water bottles and at least 5 water bottles so you should get 15 because 9+6.

The number of water bottles you would need to buy is at least 13 water bottles

let

b = water bottles

Statement 1:

at least 5 water bottles

b ≥ 5

statement 2:

at least 8 water bottles

b ≥ 8

b ≥ 13

Therefore, the number of water bottles you would need to buy is at least 13 water bottles

Answer:

The correct answer is :

1. Line PQ (One line PQ).

Step-by-step explanation:

The first step to solve this question is to draw the plane A with the points P and Q lying on it.

We know that given two different points there is only one line that contains this two different points.

Let's analyze each option.

''2. Lines PQ and QP''

This option is wrong because there aren't two different lines. In fact it is only one line that can be named line PQ or line QP.

''3. The 2 lines PQ and QP plus another line that does not lie in plane A.''

This option is assuming that exist three lines that contain P and Q. This option is also wrong.

''1. Line PQ''

This option is correct. It will be clarify with the drawing I will attach.

''We can't name them all!''

This option is assuming that exist infinite lines that contain P and Q. This option is wrong.

In the drawing I call the line that contains P and Q as line L.

Given that P and Q lie in plane A necessarily the line L must lie on the plane A.

Only one line contains points P and Q

The given parameters are:

There are at least two points in a line

This means that, a line can contain points P and Q, and any other points

Hence, only one line contains points P and Q

Answer:

x = 21

Step-by-step explanation:

Step 1: Write out equation

-5x - 72 = -12x + 75

Step 2: Add 5x to both sides

-72 = -7x + 75

Step 3: Subtract 75 on both sides

-147 = -7x

Step 4: Divide both sides by -7

21 = x

Step 5: Rewrite

x = 21

Answer:

see explanation

Step-by-step explanation:

Given

f(x) = 3x² - x + 2

To evaluate given values of x, substitute the values of x into f(x)

(a)

f(3) = 3(3)² - 3 + 2 = 3(9) - 1 = 27 - 1 = 26

(b)

f(- 5) = 3(- 5)² - (- 5) + 2 = 3(25) + 5 + 2 = 75 + 5 + 2 = 82

(c)

f(2) = 3(2)² - 2 + 2 = 3(4) = 12

(d)

f(m) = 3m² - m + 2

(d)

f(x + 2) = 3(x + 2)² - (x + 2) + 2 ← expand (x + 2)² using FOIL

            = 3(x² + 4x + 4) - x - 2 + 2

             = 3x² + 12x + 12 - x ← collect like terms

             = 3x² + 11x + 12

Answer: 5 or 55

Step-by-step explanation:

The remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

We have two numbers:

7842 and 176

7842 is divided by 176

Mathematically,

= 7842 ÷ 176

We can write the above number expression in the form of a fraction:

= 7842/176

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

The remainder will be:

Quotient = 44

Remainder = 98

Thus, the remainder is 98 when 7842 is divided by 176 after using the arithmetic operation.

Answer:

The value is  [tex]\r p  =  2.9\%[/tex]

Step-by-step explanation:

From the question we are told that

   The  number of singers is  [tex]N  =  1542[/tex]

   The  sample  size is  [tex]n  =  650[/tex]

    The  number the number of singers who are professional is k =  19

The  proportion of professional singers is mathematically represented as

       [tex]p  =  \frac{k}{n}[/tex]

=>      [tex]p  =  \frac{19}{650}[/tex]

=>    [tex]p  =  0.029 [/tex]

The  percentage estimate of singers who are professional is

      [tex]\r p  =  100 * 0.029[/tex]

       [tex]\r p  =  2.9\%[/tex]

Step-by-step explanation:

In this problem, we are expected to estimate the number of bricks he can set in 8 hours.

let us convert hours to minutes we have

60 min make 1 hour

x min make 8 hours

cross multiply

x= 60*8

x= 480 min

We are assuming the same rate with which he sets 2.5 brick is the same as the rate with which he will set bricks for the 8 hours windows

so if the bricklayer sets

2.5 bricks in 1min

y bricks in 480 min

Cross multiply we have

y=2.5*480

y= 1200  bricks

hence in 8 hours, he will set 1200 bricks

Complete question:

A student throws a heavy ball downward off the top of a building with a speed of 18m/s. The ball reaches a speed of 41m/s just before striking the ground. Neglect drag, find the height of the building.

Answer:

The height of the building is 69.235 m

Step-by-step explanation:

Given;

initial velocity of the ball, u = 18 m/s

final velocity of the ball, v = 41 m/s

The height of the building is equal to distance traveled by the ball downward.

Apply the following kinematic equation;

v² = u² + 2gh

where;

g is acceleration due to gravity

h is height of the building

41² = 18² + 2(9.8)h

1681 = 324 + 19.6h

19.6h = 1681 - 324

19.6h = 1357

h = 1357 / 19.6

h = 69.235 m

Therefore, the height of the building is 69.235 m

Answer: (2,-3)

Step-by-step explanation:

To solve by elimination method, we need to choose which variable to eliminate. Let's eliminate y. We need to make sure that the y coefficients in both equations are equal. To do that, you multiply the first equation by 5 and the second by 9.

(11x + 9y = -5)5        [multiply entire equation by 5]

(7x + 5y = -1)9          [multiply entire equation by 9]

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

55x+45y=-25

63x+45y=-9

Now that the y are both the same, we can eliminate y by subtracting both equations and solve.

-8x=-16                     [divide both sides by -8]    

x=2

Now that we have x=2, we can plug that in to any equation to find y.

7(2)+5y=-1                [multiply]

14+5y=-1                   [subtract both sides by 14]

5y=-15                      [divide both sides by 5]

y=-3      

With the y-value, we know that the answer is (2,-3).

Answer:

[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]

Step-by-step explanation:

In order to find x, our goal is to isolate it on one side of the equation.

To do this, let's first apply the distributive property on the right side of the equation.

[tex]3a+2b+cx = 8d - 10e[/tex]

Now we can subtract [tex]3a[/tex] and [tex]2b[/tex] from both sides:

[tex]cx = 8d - 10e - 3a - 2b[/tex]

And now we can divide both sides by [tex]c[/tex] so that x is alone on the left side.

[tex]x = \frac{8d-10e-3a-2b}{c}[/tex]

Answer: x= -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(x−4)+3x−9x=6−(2x+5)+8x

(5)(x)+(5)(−4)+3x+−9x=6+−2x+−5+8x(Distribute)

5x+−20+3x+−9x=6+−2x+−5+8x

−x+−20=6x+1

−x−20=6x+1

Step 2: Subtract 6x from both sides.

−x−20−6x=6x+1−6x

−7x−20=1

Step 3: Add 20 to both sides.

−7x−20+20=1+20

−7x=21

Step 4: Divide both sides by -7.

Here is how to find the distance between two points.

Find the difference between the x values.

-8-6=-14

We square this.

14²=196

We find the difference between the y values.

-2-(-1)=-2+1=-1

We square it.

-1²=1

We add up the two numbers we got.
