Find the solution set for the following equation. [tex]-\sqrt(x)=5[/tex]

Answer:

0.25

0.65

Step-by-step explanation:

P(red)= 0.35

P(green)= 0.4

Answer:

Choices B, D and E.

Step-by-step explanation:

This is simple logic.

If it was choice A, number of outfits won't be lower than number of days.

Choice B is right, because if you do this:

(3×2)(3×2)(3×2)=666 days

or

6÷3=2

(4×2)(4×2)(4×2)=888 outfits

or

8÷4=2

You would know the statement is true.

If it was choice C, it's not correct:

(3×3)(3×3)(3×3)=999 days

(4×3)(4×3)(4×3)=121212 outfits (this is the closest answer because nothing can be multiplied by 4 to get 101010)

So, statement of choice C is incorrect.

Choice D is correct, because of this:

(3×4)(3×4)(3×4)=121212 days

or

12÷3=4

(4×4)(4×4)(4×4)=161616 outfits

or

16÷4=4

E is also correct, because of this:

(3×7)(3×7)(3×7)=212121 days

or

21÷3=7

(4×7)(4×7)(4×7)=282828 outfits.

So the answer is choices B, D and E.

I hope you understand my explanation.

Answer:

14 km

Step-by-step explanation:

6 km in the afternoon

x km in the morning

6= x- 25%

6= 0.75x

x= 6/0.75

x= 8 km

total 6+8= 14 km

Answer:

9 cm

Step-by-step explanation:

Every centemeter represents three. 3km=1cm.

The number of kilometers/3= the number of centemeters.

the number of centemeters x 3= the number of kilometers.

We now have three equations to help us covert back and forth.

The question asks us to convert 27km in real life, to centemeters on a map. We use the first forumla to help us:)

The number of kilometers/3= the number of centemeters.

27/3=the number of centemeters.

Thus, the answer is nine.

Answer:

9cm

Step-by-step explanation:

1:3 this is the starting ratio

if we replace 3 for 27 we just divide them to get 9 so the new ratio is 9:27.

Answer:

2 or 3

Step-by-step explanation:

2 is one of them

3 is another of them

Answer:

no real solutions

Step-by-step explanation:

If equation is...

[tex]2x^2 - 10x - 28 = 6x(6x) - 7\\2x^2 - 10x - 28 = 6x^2 - 7\\0 = 4x^2 + 10x + 21\\4x^2 + 10x + 21 = 0[/tex]

= no real solutions

Answer:

Option (B)

Step-by-step explanation:

Given sequence is 45, 135, 405, 1215, 3645..........

Since it's a geometric sequence,

Common ratio of each successive term to the previous term

r = [tex]\frac{135}{45}=3[/tex]

First term of the sequence 'a' = 45

Explicit formula of a geometric sequence will be,

[tex]a_n=a(r)^{n-1}[/tex]

[tex]a_n=45(3)^{n-1}[/tex]

Recursive formula of this sequence will be,

[tex]a_n=3(a_{n-1})[/tex], [tex]a_1=45[/tex]

Therefore, Option (B) will be the answer.

Answer:

first complete the table by filling blank space on y axis

Then choosing a suitable scale, two squared box on the graph paper represent 1 unit for both axis.

Then draw a graph using x and y coordinate

(b) minimum value of y you dote a line from the turning point of the curve towards y axis then read the value

For this case it is -3.2

(c).To get the value of y when X=-3.5,

you dote alone from X =-3.5 on the X axis towards the curve vertically until you meet the curve then from the meeting point dote a line towards y axis and read the value.

which gives y=0.8

(d). draw a horizontal line at y=3 to meet the curve on both sides then dote a line from the meeting point vertically towards X axis and read the value on the X axis.

Answer:

See below.

Step-by-step explanation:

We have:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right)[/tex]

Simply plug in each value:

When x = 7.9, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx 0.0012[/tex]

When x = 7.99, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0001[/tex]

When x = 7.999, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx0.0000[/tex]

When x = 8.001, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0000[/tex]

When x = 8.01, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0001[/tex]

And when x = 8.1, [tex]\displaystyle \frac{1}{1+x}- \frac{1}{9} \approx-0.0012[/tex]

From this pattern, we can conclude that:

[tex]\displaystyle \lim_{x\to \-8}\left(\frac{1}{1+x}- \frac{1}{9}\right) = 0[/tex]

Since as the limit approaches 8, the value gets smaller and smaller and approaches zero.

Graphing this, we can confirm our answer.

The answer is option B.

-3 , - 0.9 , 45

Hope this helps you

Explanation:

The negative numbers are always smaller than the positive ones. So we list those first. The number -3 is smaller than -0.9 since it is further to left on the number line. So far we have -3 followed by -0.9. The last value must be 45 as its the only thing left. The sequence from smallest to largest is therefore -3, -0.9, 45. A number line is recommended to see the values being placed from left to right.

Answer:

[2,4]

Step-by-step explanation:

Answer:

y = − 2/5x − 11

Step-by-step explanation:

To answer this, we need to put it into y = mx + b form. First, we need to find the slope. The equation for that is:

[tex]m = \frac{-9 - (-7)}{-5 - (-10)}[/tex]

[tex]m = -\frac{2}{5}[/tex]

We now have the slope. Now, we need to figure out b, or the y-intercept. Using y = mx + b, we substitute the slope and an x value (it doesn't matter whether it's -10 or -5, but let's use -10 for now) and a y value (same thing).

[tex]-7 = (-\frac{2}{5})(-10) + b[/tex]

[tex]b = -11[/tex]

All that's left to do is plug it in! Our final answer is:

[tex]y = - \frac{2}{5}x - 11[/tex]

Answer:

[tex]y = - \frac{2}{5} x - 11 [/tex]

Step-by-step explanation:

[tex] (-10,-7) and (-5,-9) \\ x_{1} = - 10 \\ y_{1} = - 7 \\ x_{2} = - 5 \\ y_{2} = - 9[/tex]

[tex] \frac{y - y_{1}}{x -x_{1} } = \frac{y_{2} -y_{1}}{x_{2} - x_{1} } \\ \frac{y -( - 7) }{x - ( - 10)} = \frac{ - 9 - ( - 7)}{ - 5 - ( - 10)} \\ [/tex]

[tex]\frac{y + 7}{x + 10} = \frac{ - 2}{5} \\ cross \: multiply \\ 5(y + 7) = - 2(x + 10) \\ 5y + 35 = - 2x - 20[/tex]

[tex]collect \: like \: terms \: \\ 5y = - 2x - 20 - 35 \\ 5y = - 2x - 55 \\ \frac{ 5y = - 2x - 55}{ 5} \\[/tex]

[tex]y = - \frac{2}{5} x - 11[/tex]

Answer:

x = 108

Step-by-step explanation:

Start by finding what 2x equals

24 x 9 = 216

multiply 24 by 9 and you get 216

216 = 2x

now isolate for x by dividing both sides by 2, leaving x by itself on one side of the equation

216 / 2 = x

x = 108

Answer:

108=x

step-by-step explanation:

24(9)=2x

216=2x

216/2=2x/2

Answer:

The answers are options A and B

First solve the inequality

7x < 21

Divide both sides by 7

That's

7x/7 < 21/7

x < 3

The values that satisfy the inequality are

1 and 2 since they are both less than 3

Hope this helps you.

Answer:

Simplifying

x = 2x + -21

Reorder the terms:

x = -21 + 2x

Solving

x = -21 + 2x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2x' to each side of the equation.

x + -2x = -21 + 2x + -2x

Combine like terms: x + -2x = -1x

-1x = -21 + 2x + -2x

Combine like terms: 2x + -2x = 0

-1x = -21 + 0

-1x = -21

Divide each side by '-1'.

x = 21

Simplifying

x = 21

Answer: 267.9

Step-by-step explanation:

New diameter = 8 inches

Radius = 4 inches

Volume of a sphere = 4/3 π x r^3

= 4/3 * 3.14 * 4^3

= 267.9 cu. in.

The perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Perimeter of a rectangle  = 2 (length and breadth)

the scale of the drawing is 1:500

let's assume that the length of the scale drawing playground is x and the breadth of the scale drawing playground is y. therefore, the length of the playground is 500x and the breadth is 500y.

Perimeter of the scale drawing playground = 2(length+breadth)

                                                                        [tex]= 2 (x+y)[/tex]

Perimeter of the real playground = 2(length+breadth)

                                                       [tex]=2 (500x+500y)\\=2 \times 500(x+y)\\= 1000 (x+y)[/tex]

Hence, the perimeter of the real playground is 1000(x+y) meters where x and y are the length and breadth of the scale drawing playground.

Step-by-step explanation:

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

Resposta: 73 ° C

Explicação passo a passo:

Dado o seguinte:

Temperatura (T1) na decolagem localizada a 800 metros acima do nível do mar = 32 ° C

Temperatura (T2) à altitude máxima de 3200 metros acima do nível do mar = - 41 ° C

Portanto ;

A variação da temperatura externa entre o ponto de decolagem e a altitude máxima pode ser calculada por:

Diferença entre a temperatura de decolagem e a temperatura na altura máxima.

Variação externa da temperatura = (T1 - T2)

32 ° C - (-41 ° C)

= 32°C + 41°C

= 73°C
