Answer:

32

Step-by-step explanation:

Totally there are 50 tosses.  

Let the number of tosses which resulted head be x.  

Therefore the number of tosses which resulted tail is 50−x.

We get x×1+(50−x)×(−1)=14

x−(50−x)=14

x−50+x=14

x=32

Which expressions are equivalent to √/32?<br> 4√8<br> 08<br> 2√8<br> 4√2<br> 16<br> 16√2
vaieri [72.5K]

Answer: 4√2

square root of a number is the factor that we can multiply by itself to get that number.

The square root symbol is also called as a RADICAL.

Perfect squares are the squares of the integers also called as square numbers.

to find the square root of non-perfect squared numbers we have to check the number with a near-perfect squared numbers

how to find square root of non perfect squared numbers:

If we can't figure out what factor multiplied by itself will result in the given number, we can make a factor tree.

Factor tree of 32 = 2*2*2*2*2

                            = (2*2) * (2*2) *2

                            = (4)2 *2

Therefore √/32 = √/2*2*2*2*2

                          = √/(4)2*2

                          = 4√/2

PLS HELP ME 50 POINTS!!!!! I NEED AN ANSWER ASAP!!!!!!
Sholpan [36]

Answer:

They went up 16 levels.

Step-by-step explanation:

You can find that by finding the distance from -2 to 14.
To find the distance from two numbers, a and b, we can substitute both in the formula d = |b - a|, where d is the distance between them.

d = |14 - (-2)| \to |14 + 2|\to|16|\to16

Answer:

A=266CM

Step-by-step explanation:

p=2l + 2w                                   l=2x+1             w=x+5

66=2[2x+1] + 2{x+5]                  l=2x9 + 1           w=9+5

66=4x+2 + 2x+10                      l=18+1                 w=14

66=6x+12                                   l=19

66-12=6x

54=6x                                      A=L x W

x=9                                         A=19 x 14

                                             A=266CM
