Answer:

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It may be referred to as scientific form or standard index form, or standard form in the UK.

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

Step-by-step explanation:

I think that's the answer I hope it helps you.

Step-by-step explanation:

13x - 26 °+ 5x +8° = 180° ( being co- interior angle)

13x + 5x - 26 °+ 8° = 180°

18x - 18 = 180°

18x = 180°- 18°

18x = 162°

x= 162° ÷ 18

x= 9°

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, 11, 2, 25, 66, 5, 12, 25, 45

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:

We have the formula for pyramid volume V = (B.h)/3 => B = 3V / h

=> B = (216 . 3)/8 = 81 m2

the base area of a square pyramid : 81 m2

Step-by-step explanation:

Answer:

81cm2

Step-by-step explanation:

Volume = 1/3Base area * height

216 =1/3x * 8

3/8*216 =8/3x *3/8

x=81cm2

Answer:

Yes

Step-by-step explanation:

Given a number, a

Square of number = a²

Square root of number = √a² = a

Assume a = 4

The square of 4 = 4² = 16

The square root of 16 = √16 = 4

Hence, Grogg is correct
