Step-by-step explanation:

Right to Left

Number of 6th graders that are very unhappy is 14

Number of 6th graders that are happy is 13

Number of 7th graders that are neutral is 12

Number of 7th graders that are happy is 30

Total number of 7th graders is 80

Number of 8th graders that are very unhappy is 20

Number of 8th graders that are very happy is 2

Number of unhappy students is 59

Number of very happy students is 25

Total number of 7th graders = 196 - 50 - 66 = 80

The number of 7th graders that are neutral = 31 - 10 - 9 = 12

The number of 6th graders that are happy = 80 - 13 - 22 - 3 - 12 = 30

The number of 6th graders that are happy = 44 - 1 - 30 = 13

The number of 6th graders that are very unhappy = 66 - 10 - 10 - 19 - 13 =  14.

The number of 8th graders that are very unhappy = 37 - 3 - 14 =  20

Total number of unhappy students = 19 + 22 + 18 = 59

Answer:

240 cm^3

Step-by-step explanation:

The solid is composed by two rectangular parallelepipeds. To find the total volume  we have to find the volume of the two solids and added up.

To find the volume of a parallelepiped we have to use this formula:

V = base surface x height

The area of rectangle is : base x width

So:

Area first rectangle: 4 x 6 = 24 cm^2

V = 24 x 7 = 168 cm^3

Area second rectangle: 4 x 2 = 8 cm^2

V = 8 x 9 = 72 cm^3

total volume = 168 + 72 = 240 cm^3

Answer:

The number printed in red color = 5

The number printed in silver color = 8

The number printed in blue color = 1

Step-by-step explanation:

P.S - The exact question -

Given - The diagram

To find - The number that represent Red, Silver and Blue color.

Proof -

Let the number printed in red color = r

Let the number printed in silver color = s

Let the number printed in blue color = b

Also,

Given that the equation is -

  b s r

  b s r

+ b s r

= r  r  r

Now,

We have to think of a number that if we add the last digit of the number gives the same last digit.

Bt inspection ,

the number would be 5

Because 5 + 5 + 5 = 15

Lat place of the equation is same

So,

The number printed on red color = 5

⇒r = 5

So, the equation becomes

  b s 5

  b s 5

+ b s 5

= 5  5  5

Now,

We have to think of a number whose last digit add up to 3  + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)

i.e.

s + s + s + 1 = number whose end digit is 5

By inspection,

The number would be 8

because 8 + 8 + 8 + 1 = 25

So,

we get

s = 8

So, the equation becomes

  b  8  5

  b  8  5

+ b  8  5

= 5  5  5

Now,

By same process , we will find the number of blue color

By inspection the number on blue color = 1

∴ we get

The number printed in red color = 5

The number printed in silver color = 8

The number printed in blue color = 1

and the equation is -

  1  8  5

  1  8  5

+ 1  8  5

= 5  5  5

Answer:

13

Step-by-step explanation:

for example, Sum of 5 no. = 7×5=35

Sum of 8 no. = 8.5×8=68

Sum of added all three no. = 68 - 35 = 33

average of three new numbers = 33/3=11

The number 25 is added then the average becomes 10.

The average is defined as the ratio of the sum of the data to the total numbers of the data.

Average = ( Sum of the numbers ) / ( number of the data )

Given that the average of 5 numbers is 7. when one more number is added the average becomes 10.

The number added is calculated as:-

Sum of the numbers = 5 x 7 = 35

Let x is the number added.

Sum of the numbers = 35 + x

We know that some of the numbers = 10 x 6

35 + x = 10 x 6

35 + x = 60

x = 60 - 35

x = 25

Hence, the number added is 25.

Answer:

360 approx

Step-by-step explanation:

Given data

We want to find the total number of customers that bought gas

Let the total number of customers be x

So

72% of x = 259

let us solve for x

72/100*x= 259

0.72*x=259

x= 259/0.72

x= 359.72

Hence the actual number of customers is 360 approx

The angle that has nothing in it is going to be 54, leaving x to be 78

x=78 degrees

Answer:

A. the $5 off coupon

Step-by-step explanation:

10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more

The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.

Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.

Coupon 1 : 10% x 29.9 = $3

Coupon 2 : 29.90 - $5 = $24.90

Answer:

[tex] \sqrt{125 } \\ = 11.18[/tex]

It is in between 0 to 12.

Answer:

√125 must be between 11 and 12.

Step-by-step explanation:

Identify perfect squares in the neighborhood of 125:  

121 = 11^2      or      √121 = 11

144 = 12^2               √144 = 12

√125 must therefore be between 11 and 12.

Answer:

6 units

Step-by-step explanation:

The formula for calculating the distance between two points is expressed as;

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Given the coordinate points  E=(-6,8) and N=(-1,5)

[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]

Hence the distance between the points is approximately 6 units

Answer:

114.24°

Step-by-step explanation:

7(15)+6= 105

3(15)= 45, now we plug it in the formula, [tex]a^{2}+b^{2}=c^{2}[/tex]

[tex]105^{2}+45^{2} = 13050[/tex]

so now we square root it

[tex]\sqrt{13050}[/tex]= 114.24

Step-by-step explanation:

111^2 + 45^2 = 14346

then take the square root of 14346

which is 119.77

Answer:

I suppose we want to find the side length of the square.

We know that:

The area of the square is 49cm^2

The distance between one of the vertices of the square and the middle of the square is:

BE = 4.95cm

Now let's remember some things.

For a square of side length L, the area is:

A = L^2

and the diagonal length is:

D = √(2)*L

In this case, we know that half of the diagonal is equal to:

BE = 4.95 cm

Then the diagonal is:

D = 2*BE = 2*4.95cm = 9.9cm

And for the diagonal formula, we have:

D =  9.9cm = √(2)*L

Then the side length is:

L = 9.9cm/√(2) = 7cm

And if we check the area of this square, is:

A = L^2 = (7cm)^2 = 49cm^2

So it checks.

Then we can conclude that the sidelength of the square is 7cm, which means that:

AB = 7cm

BC = 7cm

CD = 7cm

DA = 7cm
