Answer:

8) 25.12

9) 15.07

10) 48.98

11) 1962.5

12) 20

13) r = 8.5

14) diameter: 72 radius: 36

Answer: 0.8

Step-by-step explanation:

Solution:

1. Since the numbers must be divisible by 2 even numbers, all odd numbers are ruled out because odd numbers are not divisible with even numbers.

In this case, the numbers that are possible are:

2. Since the numbers must be divisible by 5, it rules out a few more numbers.

In this case, the remaining numbers are:

We can clearly tell that the only number that is divisible by 8, 5, and 4 is 80.

Thus, 80 is the number.

Step-by-step explanation:

First I would look at the y intercept. In a linear equation, y = mx + b, b is the y-intercept and m is the slope. This means that (0,6) is a point on the line since at a y-intercept, the x value is 0. First you should plot this point.

Next, the slope is 4, meaning that for every 1 unit to the right, the line rises 4 units. You can count 1 to the right and 4 up from the y-intercept, which gives you (1,10), a second point on the line. After this, you can connect the two points and there you go, you have a graph!

The product of prime polynomials  [tex]\rm 3x(x-3)(x^2+3x+9)[/tex] is equivalent to  

[tex]\rm 3x^4-81x[/tex].

It is given that the polynomial  [tex]\rm 3x^4-81x[/tex].

The product of prime polynomials is equivalent to the above polynomial.

Polynomial is the combination of variables and constants in a systematic manner with "n" number of power in ascending or descending order.

We have:

[tex]\rm 3x^4-81x\\\rm 3x(x^3-27)\\\rm 3x(x^3-3^3)\\\rm 3x(x-3)(x^2+3x+3^2) \\\\ We \ know \ that \ a^3-b^3=(a-b)(a^2+ab+b^2)\\3x(x-3)(x^2+3x+9)\\[/tex]

Thus the option  [tex]\rm 3x(x-3)(x^2+3x+9)[/tex] is correct.

Answer:

2.05 inches

Step-by-step explanation:

V = 4/3 x πr³

36=4πr³/3

36x3= 4πr³

108= 4πr³

108/4 = πr³

27= πr^3

27/π =r³

r=

[tex] \sqrt[3]{27 \div \pi} [/tex]

r= 2.048in

round off to 2.05in

PROOF

V = 4÷3 x πr³

V= 4/3 x π(2.05)³

V=4/3 x π8.6

V=4×π×8.6/3

V=108/3

V=36in³

Therefore: radius= 2.05 inches

Answer:

f(-2) = 8

Step-by-step explanation:

Graph y = f(x)

Find value of f(-2)

when f(x) = f(-2)

Here we are looking for the value of y when x = -2

From the graph when x = -2 then y = 8

Therefore, f(-2) = 8

[tex]\begin{array}{ccll} paint&flowers\\ \cline{1-2} \frac{2}{9} & 1\\ x& 3 \end{array} \implies \cfrac{~~ \frac{2}{9}~~}{x}=\cfrac{1}{3}\implies \cfrac{2}{9x}=\cfrac{1}{3} \\\\\\ 6=9x\implies \cfrac{6}{9}=x\implies \cfrac{2}{3}=x[/tex]

Step-by-step explanation:

Substitute the value of y into the equation;

[tex]8x-2(4)=48[/tex]

Find the value of x.

Multiply;

[tex]8x-8=48[/tex]

Add 8 to each side;

[tex]8x=56[/tex]

Divide each side by 8;

Answer:

x = 7

Step-by-step explanation:

Given:

Step-1: Substitute the y-variable in the equation (8x – 2y = 48)

Step-2: Simplify the L.H.S

Step-3: Add 8 both sides

Step-4: Divide 8 both sides

b. $53

explanation:

make equations from given information.

equation 1 from plan A :

20 + 0.11(n)

equation 2 from plan B :

14 + 0.13(n)

Solve them simultaneously,

14 + 0.13(n) = 20 + 0.11(n)

0.13(n) - 0.11(n) = 20 - 14

0.02(n) = 6

n = 300

insert n = 300 in any of the equation, to find cost.

14 + 0.13(n)

14 + 0.13(300)

Answer:

1440°

Step-by-step explanation:

Each exterior angle of a 10 sided regular polygon =360/10=36°  

Each interior angle = 180°-36° =144°.  

Sum of all interior angles = 144°×10. = 1440°.

Answer: Left 2

Step-by-step explanation:

Move 2 units back which is left

Step-by-step explanation:

Since angles opposite congruent sides in a triangle are congruent, w=67.

Now, since the sum of the measures of the interior angles of a triangle is 180 degrees, x=180-67-67=46

Step-by-step explanation:

These two triangles are congruent triangles. This means that the side measurements can be found through a single multiplicative number.

All you have to do is divide 49 by 23 and get 2.130434783. You need that number to be specific

Next you want to multiply that number by the side length that corresponds to the length you are trying to find. In this case that is 7.  

7 x 2.130434783=14.9

Answer:

Step-by-step explanation:

So the total # of socks is 25 + 15+ 20, which equals 60.

theres ONLY 20 socks that are colorful, meaning that 20/60 are coloful.

20/60 simplified is 2/6, simply that even further its 1/3, 1/3 is a ration within itself. itll be 1:3

Answer:

1:3 (20:60)

Step-by-step explanation:

So the ratio of colorful socks to total socks is 20:60

This is how:

First write the number of colorful socks which is 20.

From the calculate the total number of socks( 20 + 25 + 15 = 60) which is 60.

Then put a colon and write 60

You need to write the number of colorful socks because that is what was mentioned first then the total number of socks because it was mentioned after the number of colorful socks.

So you can reduce 20:60 to its lowest term.

You write 20: 60 as a fraction [tex]\frac{20}{60}[/tex]

Then reduce [tex]\frac{20}{60}[/tex] to its lowest term which is [tex]\frac{1}{3}[/tex].

Then write [tex]\frac{1}{3}[/tex] as a ratio which is 1:3

Step-by-step explanation:

I am doing this problem assuming that you mean to solve for m and n as x and y do not exist in this system of equations.

-4m+2n=6

-4m+n=8

We can see that the coefficient of x for both equations are -4; therefore, elimination with subtraction is possible.

First equation - second equation

n=-2

Then substitude back in to solve for m

-4m+(-2)=8

4m=10

m=5/2

Therefore the answer is

n= - 2

m= 5/2
