Answer:

84

Step-by-step explanation:

(The sum of 82, 74, and 96 would be 252. And the count of numbers included in the question would be 3, and so you would divide the count from the sum as shown like Sum/Count. In this case it'd be 252/3, and that would equal 84.)

Average =  Sum/Count  

=   252/3  

=  84

Answer:

1/3x  +1/3

Step-by-step explanation:

2/3x + 1/3 - 1/3x

Combine like terms

2/3 x - 1/3x     +1/3

1/3x         +1/3

Answer:

1/3x + 1/3

Step-by-step explanation:

Solution: put all alphabets and numbers at one side.

2/3x + 1/3 - 1/3x =

2/3x - 1/3x + 1/3 =

1/3x + 1/3

Given:

A train travels 288 km at a uniform speed.

If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

To find:

The initial speed of the train.

Solution:

Let x km/h be the initial speed on the train.

New speed of train = (x+4) km/h

We know that,

[tex]Time=\dfrac{Distance}{Speed}[/tex]

Time taken by the train initially to cover 288 km is [tex]\dfrac{288}{x}[/tex] hours.

New time taken by the train to cover 288 km is [tex]\dfrac{288}{x+4}[/tex] hours.

It is given that If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

[tex]\dfrac{288}{x}-\dfrac{288}{x+4}=1[/tex]

[tex]\dfrac{288(x+4)-288x}{x(x+4)}=1[/tex]

[tex]288x+1152-288x=x^2+4x[/tex]

[tex]1152=x^2+4x[/tex]

[tex]0=x^2+4x-1152[/tex]

Splitting the middle term, we get

[tex]x^2+36x-32x-1152=0[/tex]

[tex]x(x+36)-32(x+36)=0[/tex]

[tex](x+36)(x-32)=0[/tex]

[tex]x=-36,32[/tex]

We know that the speed cannot be negative. So, the only possible value of x is 32.

Therefore, the speed of the train is 32 km/h.

Answer:

RMN+117°=180°

RMN=180°-117°

RMN=63°

SUM OF ANGLE ON A STRAIGHT LINE ADD UP TO 180°

Answer:

- the angle at H is 120 degrees

- the missing segment is DC

Step-by-step explanation:

The "roof" FGH is bigger than 90 degrees because FG and GH are not acute. .

Without instruction we can assume FGH is 120 degree.

This means GHF is 30 degrees to complete the triangle FGH.

So the angle around H, or JHG is 90 + 30 = 120 degrees

For the ratio, we can simply look at the comparison between the small figure   DJHGF

and the large figure DCBAE, and we see that the denominator

DJ in the small figure is DC in the large figure.

Answer:

According to the graph it should be D  Have a good day thank you <.>

Answer:

4(2qp + 5qr - 4s)

Step-by-step explanation:

8pq + 20qr – 16s

we can use 4 as a common factor between these numbers.

8/4 = 2

20/4 = 5

16/4 = 4

so

4(2qp + 5qr - 4s) is the most factorized answer we can get

Answer:

140

Step-by-step explanation:

From the 1st base to the 2nd base is 70 feet.

From 2nd base to 3rd base is 140 because 70×2=140.

Another way to do this is 70+70=140.

Hopefully this helps :)

We have:

ab = bc (hypothetical)

so the triangle ABC is isosceles at B

we have: bd is the height of the triangle ABC, so BD is perpendicular to AB

Consider the triangle ABD and the right triangle ACD have:

AB = BC (hypothesis)

BD is the common edge

So the triangle ABD = triangle ACD (hypotenuse - acute angle)

hence the angle ABD = angle ACD

It is a right triangle.

Given:

The function is:

[tex]y=6x+3[/tex]

To find:

The missing value for the given table of values.

Solution:

We have,

[tex]y=6x+3[/tex]

Substituting [tex]x=1[/tex] in the given function, we get

[tex]y=6(1)+3[/tex]

[tex]y=6+3[/tex]

[tex]y=9[/tex]

Substituting [tex]x=3[/tex] in the given function, we get

[tex]y=6(3)+3[/tex]

[tex]y=18+3[/tex]

[tex]y=21[/tex]

Substituting [tex]x=6[/tex] in the given function, we get

[tex]y=6(6)+3[/tex]

[tex]y=36+3[/tex]

[tex]y=39[/tex]

Substituting [tex]x=8[/tex] in the given function, we get

[tex]y=6(8)+3[/tex]

[tex]y=48+3[/tex]

[tex]y=51[/tex]

Therefore, the complete table of values is:

x            y

1            9

3           21

6           39

8           51

Answer:

A) 48° + 75°

Step-by-step explanation:

All triangles contain 180°

180° - 57° = 123°

A) 48° + 75° = 123°

B) 57° + 57° = 114°

D) 63° + 70° = 133°

A) 70° + 83° = 153°

[tex]\huge{\textbf{\textsf{{\color{pink}{An}}{\red{sw}}{\orange{er}} {\color{yellow}{:}}}}}[/tex]

The answer is A. 48⁰ and 75⁰

Thr sum of all triangles is 180⁰

so, 180⁰ – 57⁰ = 123⁰

The sum of other two angles should be 123⁰,

so,...

48⁰ + 75⁰ = 123⁰

Answer:

4.22in

Step-by-step explanation:

Given data

Volume= 601in^3

Height= 10.7in

Radius= ??

The expression for the volume of a cylindrical bucket is

V=πr^2h

substitute

601= 3.14*r^2*10.7

601= 33.598r^2

601/33.598= r^2

17.88=r^2

square both sides

r= √17.88

r= 4.22 in

Hence the radius of the bucket is 4.22in
