the number 0.3333 repeats forever therefore its irrational?

Answer:

obtuse and scalene

Step-by-step explanation:

at least one angle is larger than 90º, and so it's an obtuse angle.

scalene triangle means all sides of the triangle are different lengths.

Answer:

Obtuse and scalene

Explanation:

An obtuse triangle has one angle greater than 90° with the rest of the angles being acute.

A scalene triangle has all sides of different lengths.

Answer:

Step-by-step explanation:

Function 'f' represents the number of miles (y-values) covered by the helicopter in 'x' (x-values) minutes.

f(x) = 40 - 2x

For x = 0,

f(x) = 40 miles

For f(x) = 0,

0 = 40 - 2x

x = 20 minutes

This shows that helicopter traveled 40 miles in 20 minutes.

Similarly, given graph shows distance covered by the jet on y-axis and duration of flight on x-axis.

For x = 0,

f(x) = 500 miles

For f(x) = 0,

x = 100 minutes

Commercial jet traveled 500 miles in 100 minutes.

The total distance and time taken for each flight are illustrations of intercepts.

We have:

[tex]x \to[/tex] minutes

[tex]f(x) \to[/tex] miles

Helicopter

[tex]f(x) = 40 - 2x[/tex]

Set f(x) to 0, to calculate the x-intercept

[tex]0 = 40 - 2x[/tex]

Collect like terms

[tex]2x = 40[/tex]

Divide by 2

[tex]x =20[/tex]

Set x to 0, to calculate the y intercept

[tex]f(x) = 40 - 2x[/tex]

[tex]f(0) = 40 - 2 \times 0[/tex]

[tex]f(0) = 40[/tex]

This means that, the helicopter traveled 40 miles in 20 minutes

Commercial Jet

From the graph, the intercepts are:

[tex](x_1,y_1) = (100,0)[/tex] --- the x-intercept

[tex](x_2,y_2) = (0,500)[/tex] --- the y-intercept

This means that, the commercial jet traveled 500 miles in 100 minutes

Answer:

x=6

Step-by-step explanation:

5-6x=17-8x                  5-6x=17-8x

5-6(6)=17-8(6)     or     5+2x=17                 added 8x to both sides

5-36=17-48                  2x=12                    subtracted 5 from both sides

-31=-31                          x=6                       divided both sides by 2

Answer:

Since BD bisects Angle ABC, Angle ABD = Angle DBC

[tex]3x+6=7x-18[/tex]

Subtract 6 from both sides:

[tex]3x+6-6=7x-18-6[/tex]

[tex]3x=7x-24[/tex]

Subtract 7x from both sides:

[tex]3x-7x=7x-24-7x[/tex]

[tex]-4x=-24[/tex]

Divide both sides by -4:

[tex]\frac{-4x}{-4}=\frac{-24}{-4}[/tex]

[tex]x=6[/tex]

Angle [tex]ABD=3x+6=3(6)+6=18+6=24[/tex]

[tex]g=2T^2-6[/tex]

Step-by-step explanation:

To make g the subject, you have to isolate it in the form of g = (stuff)

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

[tex]T=\sqrt{\frac{g+6}{2}}[/tex]

Square both sides:

[tex]T^2=\frac{g+6}{2}[/tex]

Multiply both sides by 2:

[tex]2T^2=g+6[/tex]

Swap Sides:

[tex]g+6=2T^2[/tex]

Subtract 6 from both sides:

Answer:

7x^2 + 7

Step-by-step explanation:

So you collect the "like-terms". 3x^2 is not the same as 7, however, 4x^2 has the same term as 3x^2, so you add those together and then join the 7 in the expression.

Hope that explanation makes sense

Answer:

[tex]3x^{2} + 4 {x}^{2} + 7 = 7 {x}^{4} + 7[/tex]

Step-by-step explanation:

Because 3x² and 4x² are like terms, they can be added together:

3+4=7

²+²=⁴

Therefore, it will be 7x⁴.

But 7x⁴ and 7 are not like terms. So it is just 7x⁴+7

Answer:

Step-by-step explanation:

Mean = Sum of all data [tex]\div[/tex] Number of data

Let x be the other number.

[tex]30 =\frac{12+50+48+x}{4}[/tex]

Multiply both sides by 4:

[tex]\frac{4\left(12+50+48+x\right)}{4}=30* \:4[/tex]

[tex]x+110=120[/tex]

Subtract 110 from both sides:

[tex]x+110-110=120-110[/tex]

[tex]x=10[/tex]

Answer:

B:10

Step-by-step explanation:

Set up the equation

(12+50+48+x)/4=30

Add like terms

(110+x)/4=30

now multiply both sides by 4

(110+x)/4=30

4              4

110+x=120

Now subtract  110 from both sides

x=10

Answer/Step-by-step explanation:

a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.

b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.

c. In the 3rd row, the lower limit of the class should be 133, NOT 138.

d. Different class width were used.

Row 1 class width = 13 - 9 = 4

Row 2 class width = 19 - 14 = 5

Row 3 class width = 25 - 20 = 5

Row 4 class width = 28 - 26 = 2

Row 5 class width = 32 - 29 = 3

The reason for all the frequency distribution is given below and this can be determined by using the given data.

Check all the options in order to determine the reason for the incorrect construction.

A) The given frequency table is given below:

Class            Frequency

39-44                 6                              

45-49                 4                              

50-55                 2                              

In the fourth row, the class should be ending with 50.

B) The given frequency table is given below:

Class            Frequency          

5-9                     1                                

9-13                    2

17-20                  6                              

20-24                 3    

In the fourth row, the class should be ending with 21.

C) The given frequency table is given below:

Class            Frequency          

123-127                 3                                

128-132                 7

143-147                 19                              

In the second row, the class should be starting from 127.

D) The given frequency table is given below:

Class            Frequency          

9-13                     1                                

14-19                    6                              

20-25                  2                              

26-28                  5                              

29-32                  9  

In the second row, the class should be starting from 13.
