TiliK225 [7]3 years ago
4 0

remember that you have to do the same to both sides

\frac{x}{4}+16>34

minus 16 both sides

\frac{x}{4}+16-16>34-16

\frac{x}{4}+0>18

\frac{x}{4}>18

mulitply both sides by 4

\frac{4x}{4}>18*4

(x)(\frac{4]{4})>72

(x)(1)>72

x>72

If a thermometer indicates 40 degrees Celsius, what is the temperature in degrees Fahrenheit?
Stells [14]
<span>So we wan't to convert the temperature from Celsius scale to fahrenheit scale. The method fot that is this: First, 0 degrees Celsius or the starting point of Celsius scale is 32 degrees Fahrenheit. And the magnitude of a degree Fahrenheit is 1.8 times greater than the magnitude of a degree Celsius, or: 1F=1.8F. So now we can construct a function that will give us temperature in degrees Fahrenheit: T(F)=1.8T(C) + 32. We have T(C)= 40, and after we put that in our function we get: T(F)= 1.8*40 + 32 = 72 + 32 = 104 F. So 40 degrees Celsius is 104 degrees Fahrenheit. </span>

The circle below is centred at point (2,-1) and has a radius of length 3 what is its equation ?
NeTakaya

Answer:

Option C

Step-by-step explanation:

The standard form of equation of a cirle is:

(x-h)^2+ (y-k)^2=r^2

In the given question as the point is given and the radius of circle is given:

So,

(h,k)=(2,-1)

and

r=3

Here,

h=2

k= -1

Putting the values of h,k and r in standard form

(x-2)^2+ (y-(-1))^2=(3)^2

(x-2)^2+ (y+1)^2=(3)^2

So the equation of circle is:

(x-2)^2+ (y+1)^2=9(3)^2

Option C is the correct answer ..

Find the missing side of each triangle. Round your answers to the nearest tenth if necessary.
navik [9.2K]

Answer:

15.5 because you have to take away some point

Step-by-step explanation:

you can do 15.8 +5.3 and that would make 21 - 15 and makes 6 so you can round 15.8 to 16 and then you subtract to make 10 then you add 5

Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern.
Ahat [919]

Answer:

f(x) = 1.5x - 0.5x

Step-by-step explanation:

The function of the pattern represented by the pentagonal numbers is the sum of three triangular numbers.

The triangular number general formula

                      x (x + 1) / 2

For  example,

The sequence

1,     3,     6,      10

                                             *

                          *              *  *

         *           *   *          *   *  *

* ,    *  *,     *   *   *,     *   *   *  *

_____________________________

The pentagonal numbers

The sequence:

1, 5, 12, 22, 35

As shown in the picture can be divided into three triangles

Triangle 2

x (x + 1) / 2

Triangle 1 and 3  (they are triangles one unit smaller than 2)

n (n + 1) / 2

n= x-1

Replacing n

(x-1) ((x-1) + 1) / 2

(x-1) (x) / 2

(x-1) x / 2

______________

Function represents the pattern

Triangle 2  + (Triangle 1  +  Triangle 3)

Triangle 1  = Triangle 3

So then,

Triangle 2 + 2* Triangle 1

x (x +1) /2  + 2* (x -1) x/2

Rearranging

0.5 x (x +1) + x(x -1)

0.5x^2 + 0.5x + x^2 -x

(0.5 x^2 + x^2)  + (0.5x -x )

1.5 x^2 - 0.5 x

PLEASE HELP!!! Which rule explains why these scalene triangles are similar
olchik [2.2K]

Answer:  Ratio of Parts

<u>Step-by-step explanation:</u>

\text{Ratio of sides:}\ \dfrac{ST}{WS+ST}=\dfrac{66}{6+66}=\dfrac{66}{72}=\dfrac{11}{12}\\\\\\\text{Ratio of bases:}\ \dfrac{TU}{TU+UV}=\dfrac{44}{44+4}=\dfrac{44}{48}=\dfrac{11}{12}\\\\

The ratios are equal so the triangles are similar.
