Step-by-step explanation:

Because poly means multiple and there is 4 so it's quad. There is 4 terms so none of them say quadnomial so it is none of them.

Answer:

200,000 and 2005 which cant theoretically be done be P(t) which would increase in the population which would most likely be from 2005 to 2020. so you cannot do this because imagine it as X=(Y)x the mass of population which would be defined as (P) which will also be represented as a probable and physical change in the number. but not only the number, but the population. being have of the initial amount which you will take the variable (P) and have the exact amount which would be the population. Which would theoretically recon as a positive ID of the population.-Cj

Answer:

There are 4 sixteenths in one-fourth. To find how many sixteenths are in one-fourth, we need to divide 1/4 by 1/16.

Step-by-step explanation:

There are 4 1/16's in 1/4 inch after making a linear equation x(1/16) = 1/4 the answer is 4.

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 expression can be defined as the combination of constants and variables with mathematical operators.

Let x be the number of 1/16 in 1/4 inch

x(1/16) = 1/4

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

After simplification:

x = 16/4

x = 4

Thus, there are 4 1/16's in 1/4 inch after making a linear equation x(1/16) = 1/4 the answer is 4.

r= -3

Step-by-step explanation:

-3 r + 3(r-2) = -2(r+6)

-3r+3r-6= -2r-12

-6= -2r-12

2r=6-12

2r= -6

r= -3

Answer: x=16

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    -9/8*x-7-(-25)=0

simplify 9/8

((0 -  (9/8 • x)) -  7) -  -25  = 0

 Subtracting a whole from a fraction

Rewrite the whole as a fraction using  8  as the denominator

7 = 7/1 = 7*8/8

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

  -9x - 56  =   -1 • (9x + 56)

   Adding up the two equivalent fractions

(-9x-56) - (-25 • 8)/8     144 - 9x/8

  144 - 9x  =   -9 • (x - 16)

When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, multiply both sides of the equation by the denominator.

Here's how:

 -9•(x-16)/8 • 8 = 0 • 8

Now, on the left hand side, the  8  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  -9  •  (x-16)  = 0

   Solve  :    x-16 = 0  

Add  16  to both sides of the equation :  

                     x = 16

Answer:

1,280 cubic meters

Step-by-step explanation:

Length x Width x Height = Volume

The box on the left:

8m x 5m x 22m = 800[tex]m^{3}[/tex]

Box on the right:

12m x 5m x 8m = 480[tex]m^{3}[/tex]

Add them:

800[tex]m^{3}[/tex] + 480[tex]m^{3}[/tex] = 1,280[tex]m^{3}[/tex]

The volume of the figure is 1,280 cubic meters

Answer:

140 liters will remain after 10 mins

Step-by-step explanation:

The easy way is just multiply the amount lost per min by the number of mins.

[tex](2x - 9) + (3x - 6) = 110[/tex]

[tex]2x + 3x - 9 - 6 = 110[/tex]

[tex]5x - 15 = 110[/tex]

Plus sides 15

[tex]5x - 15 + 15 = 110 + 15[/tex]

[tex]5x = 125[/tex]

Divided sides by 5

[tex] \frac{5}{5}x = \frac{125}{5} \\ [/tex]

[tex]x = 25[/tex]

Thus ;

A = 2 ( 25 ) - 9°

A = 50° - 9°

A = 41°

_________________________________

B = 3 ( 25 ) - 6

B = 75° - 6°

B = 69°

_________________________________

C + 110° = 180°

because it is a straight line.

Subtract sides 110°

C + 110° - 110° = 180° - 110°

C = 70°
