Answer:

[tex]x=\frac{1}{3}[/tex]

Step-by-step explanation:

You cross multiply the x under 3 and multiply it by 9;

[tex]3=9x[/tex]

Divide both sides by 9;

[tex]\frac{3}{9} =x[/tex]

3/9 can also be called 1/3;

[tex]x=\frac{1}{3}[/tex]

Answer:

23.3%

Step-by-step explanation:

Formula: I=PRT (Interest=Principal*Rate*Time)

I=23400-4500=18900

18900=4500*R*18

18900=81000R

R=18900/81000=0.233... Rounds to 23.3%

Answer:

-5 < -4

|X| - this is read as magnitude of X and it means take the positive of that number X.

meaning if the number X is negative you can ignore the negative and write the positive value of the number.

so now:

|7| = 7

|5| = 5

|-5| = 5

7 = |7| not 7 < |7|

-5 < -4 is correct since on the number line numbers to the left are lesser than numbers on the right and -5 is on the left of -4 on the number line

|5| < 7 since |5| is just 5 and 5 is less than 7

|-5| > -4 not -5 < -4 since |-5| is 5 and 5 is greater than -4

hence correct answer is the second one

Answer:

~ 104 135

Step-by-step explanation:

Decreasing by 8% each year means  92% is left each year

Formula

  FV = PV ( i)^n       FV = population in future  PV = pop now  

                                       i = 92% in decimal form = .92     n = years = 5

FV = 158000(.92)^5 = 104135

A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,

Population after 5 years = 158,000(1-0.08)⁵

                                          = 158,000 × 0.659

                                          = 104134.8807 ≈ 104135

Hence, the population of the city after 5 years will be 104135.

How fast the volume of the sphere is changing when the surface area is 10 square centimeters is it is increasing at a rate of 30 cm³/s.

To solve the question, we need to know the volume of a sphere

The volume of a sphere V = 4πr³/3 where r = radius of sphere.

To find the how fast the volume of the sphere is changing, we find rate of change of volume of the sphere. Thus, we differentiate its volume with respect to time.

So, dV/dt = d(4πr³/3)/dt

= d(4πr³/3)/dr × dr/dt

= 4πr²dr/dt where

Given that

Substituting the values of the variables into the equation, we have

dV/dt = 4πr²dr/dt

dV/dt = 10 cm² × 3 cm/s

dV/dt = 30 cm³/s

So, how fast the volume of the sphere is changing when the surface area is 10 square centimeters is it is increasing at a rate of 30 cm³/s.

Answer:

O 4th option : (-4, -2)

Step-by-step explanation:

⇒ 9x - 9y = -18

⇒ -6x + 9y = 6

⇒ (x , y)

⇒ (-4, -2)

Answer:

(-4, -2)

Step-by-step explanation:

When using the elimination method, we combine the equations to get one. To combine them, we have to find a term with a number that is either positive or negative to the other, example : -6y and 6y, or 4x and -4x. We then take them and combine both equations to get one. Becuase they are the same, they simply cancel each other out.

9x - 9y = -18

-6x + 9y = 6

3x = -12

Divide both sides by 3 to get x alone

x = -4

Now, to find the y value, we can now plug in what we found for x.

9(-4) - 9y = -18

-36 - 9y = -18

Add 36

-9y = 18

Divide by -9

y = -2

Therefore making the solution, (-4, -2)

The area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

A=a\times b

Here, (a)is the length of rectangle and (b) is the width of the rectangle

The given figure is in two parts. It is made with 2 semicircles and 1 rectangle. The length of the rectangle part is 8 ft and width of it is 4 ft long. Thus, the area of this part is,

[tex]A_r=8\times4\\A_r=32\rm\; ft^2[/tex]

There are two semicircles, which make one complete circle. Thus, the area of this two semicircle with radius 2 ft, is,

[tex]A_c=\pi \times2^2\\A_c=12.57\rm\; ft^2[/tex]

Thus, the area of this composite figure is,

[tex]A=A_r+A_c\\A=32+12.57\\A=44.57\rm\; ft^2\\A=44.6\rm\;ft^2[/tex]

Thus, the area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².

Answer:

Mean=30

Median=30.5

Mode=None

Range=11

Step-by-step explanation:

The mean is all the numbers added together then divided by how many numberes there are.

24+28+33+35=120

120/4=30

Median is the the middle of the data set when arranged least to greatest. Since its a even number the median will consist of two numbers. 28 and 33

28+33=61

61/2=30.5

Mode is the number most seen in the data set. Theyre all seen once so no mode

Range is the highest value subtracted from the lowest.

24-35=11
