The value of x after completing the steps is -16

Given the equation solved by Lorie expressed as":

[tex]10(0.5x+2) - 5=3(x-6)+1[/tex]

Expand the bracket using the distributive law as shown:

5x + 20 - 5 = 3x - 18 + 1

Collect the like terms:

5x - 3x = -18 + 1 - 20 + 5

Simplify by adding and subtracting

2x = -32

Divide both sides by 2:

2x/2 = -32/2

x = -16

Hence the value of x after completing the steps is -16

Answer:

[tex]\huge\boxed{j=38}[/tex]

Step-by-step explanation:

[tex]\dfrac{j}{-2}+7=-12\qquad\text{subtract 7 from both sides}\\\\\dfrac{j}{-2}+7-7=-12-7\\\\\dfrac{j}{-2}=-19\qquad\text{multiply both sides by (-2)}\\\\(-2)\!\!\!\!\!\!\!\diagup\cdot\dfrac{j}{-2\!\!\!\!\!\diagup}=(-2)(-19)\\\\j=38[/tex]

Answer: j = 38

Step-by-step explanation: First isolate j/-2 by subtracting

7 from both sides of the equation.

That gives you j/-2 = -19.

From here, since j is being divided by -2, multiply

both sides of the equation by -2 so j = 38.

Answer: x=6, y=20

Step-by-step explanation:

Since ΔBCD and ΔTUS are congruent triangles, we can set the sides equal to each other.

y=2y-20                           [subtract both sides by 2y]

-y=-20                              [divide both sides by -1]

y=20

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

3x+32=9x-4                    [add both sides by 4, and subtract both sides by 3x]

36=6x                              [divide both sides by 6]

x=6

Responda:

P (verde) = 8/15

P (vermelho) = 1/3

P (azul)). 2/15

P (verde ou azul) = 2/3

P (não verde) = 7/15

Explicação passo a passo:

Dado o seguinte:

Número de bolas verdes = 8

Número de bolas vermelhas = 5

Número de bolas azuis = 2

N (verde) = 8

N (vermelho) = 5

N (azul) = 2

Portanto, número total de bolas;

N (total) = 8 + 5 + 2 = 15

Probabilidade = número de resultados requeridos / Total de resultados possíveis

1.) Probabilidade de escolher uma bola verde:

P (verde) = número de bolas verdes / número total de bolas

P (verde) = 8/15

2.) Probabilidade de pegar uma bola vermelha: P (vermelho) = número de bolas vermelhas / número total de bolas

P (vermelho) = 5/15 = 1/3

3) Probabilidade de pegar uma bola azul:

P (azul) = número de bolas azuis / número total de bolas

P (azul) = 2/15

4) probabilidade de verde ou azul:

P (verde ou azul) = P (verde) + p (azul)

P (verde ou azul) = 15/8 + 2/15 = 10/15 = 2/3

P (não verde) = 1 - P (verde)

P (não verde) = 1-8/15

P (não verde) = 7/15

Decreasing order means from greatest to least.

Obviously, positive numbers are greater than negative numbers, so we put the positive numbers first. 58>13>-35>-51.

(Note that with negatives, a greater number is a number closer to zero!)

Answer:

A

Step-by-step explanation:

The altitudes have to be arranged in decreasing order.

58 > 13 > -35 > -51

Answer: 1035 cm^2

Step-by-step explanation:

Given that the shape s is exactly one quarter of solid sphere.

Where the volume of the shape s is 1994πcm^3.

The formula for volume of a sphere is

V = 4/3πr^3

The volume will be divided by 4 since the given solid is exactly quarter of solid sphere. Then equate it to the given value

1994π = 4/3πr^3 × 1/4

The π will cancel out

1994 = r^3/3

Cross multiply

5982 = r^3

r = cube root of 5982

r = 18.2 cm

The surface area of a sphere is

A = 4πr^2

Substitute r in the formula

A = 4× π × 18.2^2

A = 4141

Since the shape is exactly one quarter of solid sphere. Divide the answer by 4

A = 4141/4

A = 1035.3 cm^2

The surface area of s is therefore 1035.3 cm^2

The surface area of the shape s is approximately 329.53 cm².

Important information:

Volume of a sphere is:

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

The volume of one-quarter of a solid sphere is 1994π cm².

[tex]1994\pi=\dfrac{1}{4}\times \dfrac{4}{3}\pi r^3[/tex]

[tex]1994\pi=\dfrac{1}{3}\pi r^3[/tex]

[tex]\dfrac{1994\pi\times 3}{\pi}=r^3[/tex]

[tex]5982=r^3[/tex]

Taking cube root on both sides, we get

[tex]\sqrt[3]{5982}=r[/tex]

[tex]r\approx 18.153[/tex]

Surface area of a sphere is:

[tex]S=4\pi r^2[/tex]

Surface area of one quarter of solid sphere is:

[tex]S=\pi r^2[/tex]

[tex]S=\pi (18.153)^2[/tex]

[tex]S=329.5314\pi[/tex]

[tex]S\approx 329.53\pi[/tex]

Therefore, the surface area of the shape s is 329.53 cm².

Answer:

Hey there!

We want to change the equation for each line into slope intercept form, or y=mx+b form.

Luckily, the first one is already in slope intercept form.

The second line can be converted to: y=-3/4x-7/4.

The third line can be converted to: -8y=-6x+4, or y=3/4x-1/2

Line one and line two are neither perpendicular or parallel.

Line one and line three are perpendicular.

Lines two and three are neither perpendicular or parallel.

This is because parallel lines have same slope, and perpendicular lines have opposite reciprocal slopes.

Hope this helps :)

Answer:

Line 1 and Line 2: Neither

Line 1 and Line 3: Perpendicular

Line 2 and Line 3: Neither

Step-by-step explanation:

To make the answering process easier, begin by converting each formula into the format y = mx +b:

Line 1: y = -4/3x + 1 (already in format)

Line 2:

-4y = 3x + 7

Divide all terms by -4:

y = -3/4x - 7/4

Line 3:

6x - 8y = 4

Subtract both sides by 6x:

-8y = -6x + 4

Divide all terms by -8:

y = 3/4x - 1/2

We can determine the relationships of the lines:

Line 1 and Line 2: Neither. They do not have the same slope, and they are not opposite reciprocals of each other.

Line 1 and Line 3: Perpendicular. The slopes of each line are opposite reciprocals: (-4/3 and 3/4)

Line 2 and Line 3: Neither. The slopes are the same but one is negative.

a. 5p + 3

b. 26p + 6

2.

a r = (v ÷(pi)h)½

b. r = 3.74 to the nearest hundredth

Step-by-step explanation:

1.

Area of deck = 40p² + 24p

Width of deck = 8p

Area = length × width(breadth)

a. Area = length × width

40p² + 24p = length × 8p

Factorise out 8p from the left hand side

8p(5p + 3) = length × 8p

Divide both sides by 8p

5p + 3 = length

b Perimeter of deck = 2 (length + width)

"" = 2(5p+3 + 8p)

"" = 2 (13p + 3)

"" = 26p + 6

2.

Volume = 200 mm³

Height = 17mm

a. isolate the r in the equation v = (pi)r²h

v = (pi)r²h

Divide both sides by (pi)h

v ÷ (pi)h = r²

Take the square roots of both sides

(v ÷ (pi)h)½ = r

b. find r using your answer in a.

r = (v ÷ (pi)h)½

r = (200 ÷ ( 22/7 × 17))½

r = (200 ÷ 53.4286)

r = 3.7433

Step-by-step explanation:

Start with the average. (of your data set)

Find how much each data value deviates from the average (difference of average and data value).

Take the absolute value of each difference.  

Add all of these absolute values.

Divide by the total number of data values.

How to find the MAD (Mean Absolute Deviation):

Let's use these numbers to figure out the MAD:

[tex]5, 2, 1, 3[/tex]

1. First thing you want to do is add the numbers together:

[tex]5+2+1+3=11[/tex]

2. Second thing you want to do is divide it by 4 because there are 4 numbers in the data set:

[tex]\frac{11}{4} =2.75[/tex]

3. Third thing you want to do is subtract the data set from 2.75:

[tex]5-2.75=2.25\\2.75-2=0.75\\2.75-1=1.75\\3-2.75=0.25[/tex]

4. Fourth thing you want to do is add all the differences:

[tex]2.25+0.75+1.75+0.25=5[/tex]

5. Last thing you want to do is now divide the sum (5) by 4 again:

[tex]\frac{5}{4}= 1.25[/tex]

So, the answer (MAD) would be 1.25

That's how you find the MAD to any data set in steps.

Step-by-step explanation:

This is false because a population represents all and not some. A population is the collection of all outcomes, responses, measurements, or counts that are of interest. It is not a collection of 'some' outcomes. It is a collection of 'all' outcomes.

A population data set is a set which contains all the items or elements of a specified group or data set. It is a complete list of all the possible data values.

The sample of a population are drawn out of a population. They are A subset of a population.

Answer:  A. (10, 5)

Step-by-step explanation:

Inverse variation means xy = k

Given: x = 5, y = 10 --> k = 5(10) = 50

A. 10(5) = 50    This works!

B. -5(10) = -50  

C. -10(5) = -50

D. 5(-10) = -50

The only option that results in k = 50 is option A.

Area of the circle = π * (35 yd)^2

Let A be the area of the sector subtended by a central angle measuring 80º. Then

A / (π * (35 yd)^2) = 80º / 360º  ==>  A = 2450π/9 yd^2 ≈ 854.78 yd^2

Subtract from A the area of the triangle, whose base has length 45 yd and with height 25 yd:

A - 1/2 * (45 yd) * (25 yd)  ≈ 292.28 yd^2

This is the area of the missing circular segment.

Then the area of the playground is equal to the area of the circle minus this area,

π * (35 yd)^2 - 292.28 yd^2 ≈ 3554 yd^2

Average rate of change in dollars per year between years 15 to 20 is:

$5300 per year.

Step-by-step explanation:

Given that:

Initial Investment, P  = $5000

Formula:

[tex]A(t) = P(1.06)t[/tex]

To find: If James invests $5000,

average rate of change in dollars per year (rounded to the nearest dollar) between years 15 and 20=?

Solution:

First of all, let us find out A(15) and A(20):

Putting t = 15 first,

[tex]A(15) = 5000(1.06)\times 15 ....... (1)[/tex]

Putting t = 20,

[tex]A(20) = 5000(1.06)\times 20 ....... (2)[/tex]

Average rate of change / year is defined as:

[tex]\dfrac{\text{Change in value of A}}{\text{Number of years}}[/tex]

So, required rate of change:

[tex]\dfrac{A(20)-A(15)}{5}\\\Rightarrow \dfrac{5000 \times 1.06 \times 20-5000 \times 1.06 \times 15}{5}\\\Rightarrow \dfrac{5000 \times 1.06 \times (20-15)}{5}\\\Rightarrow \dfrac{5000 \times 1.06 \times 5}{5}\\\Rightarrow 5000 \times 1.06\\\Rightarrow \$5300\ per \ year[/tex]

So, the answer is:

Average rate of change in dollars per year between years 15 to 20 is:

$5300 per year.
