Answer:

It is y>-10

Step-by-step explanation:

i did it and i got it right.

The inequality that represents elevations above -10 meters is y > -10.

It shows a relationship between two numbers or two expressions.

There are commonly used four inequalities:

Less than = <

Greater than = >

Less than and equal = ≤

Greater than and equal = ≥

We have,

The inequality y > -10 means that the elevation y of a passage is greater than -10 meters.

This represents all the elevations of passages that are above -10 meters, which is the given condition in the problem.

If the elevation is exactly -10 meters or below, then it does not meet the condition of being above -10 meters.

Therefore, any elevation that is greater than -10 meters satisfies this inequality, and any elevation that is less than or equal to -10 meters does not.

Thus,

The inequality that represents elevations above -10 meters is y > -10.

Answer:

Step-by-step explanation:

Let  n=2α⋅5β⋅m , where  gcd(m,10)=1 . Then, the decimal expansion of  1n  is of the form

0.a1…akak+1…ak+ℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(1) ,

where  k=max{α,β}  and  ℓ  is the least positive integer for which  m∣(10ℓ−1) . In other words,  ℓ  is the order of  10  in the multiplicative group of units modulo  m . So  ℓ∣ϕ(m)  by Lagrange's theorem.

In particular, if  gcd(n,10)=1 , then  α=β=k=0 ,  m=n , and

1n=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(2)  

Therefore, we know that

117=0.a1…aℓ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯(3)  

Here  ℓ  is the least positive integer for which  17  divides  9…9ℓtimes , and we know that  ℓ  divides  ϕ(17)=16 .

Successively squaring  10  modulo  17  gives

102≡−2(mod17),104≡4(mod17),108≡−1(mod17),1016≡1(mod17) .

So  ℓ=16  in expansion  (3) .

In fact,

a1…a16×17=1016–1.  

a1…a8+a9…a16=108−1 .

The first fact has nothing to do with the denominator  n  being prime. The second fact has everything to do with  n  being prime, and was discovered by E. Midy in  1836 .

Explanation: The power rule tells us that when we have a power taken to another power, we keep the base the same and we multiply the exponents.

So we have p¹⁰ which is our final answer.

Answer:

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over

Step-by-step explanation:

Find the "unit length" by dividing 1 m by 3.6 cm:

  1 m

-----------

3.6 cm

Recall that 1 m = 100 cm.  Multiply the following by the conversion factor 100 cm / 1 m:

  1 m            100 cm

----------- * ----------------- = 27,7777777...

3.6 cm            1 m

We can get 27 pieces of wire 3.6 cm long and have a piece 7/9 cm left over (verify this by dividing 7 by 9 on a calculator).

Answer:

Pieces can be cut = 1/3.6

Pieces can be cut = 0.27 m

100 cm = 1 m

0.27 m = 27 cm

Therefore,

The length remaining of wire is 27 cm (approximately)

Answer:

Michael should get $0.25 from the clerk.  

Step-by-step explanation:

Add $1.25+$0.50 together which equals $1.75 and multiply $0.25x8 which equals $2.00 and subtract $1.75 from $2.00 and that equals $0.25.

Answer:

.25 = 1 quarter

Step-by-step explanation:

8 x .25 = $2.00

1.25 + .50 = $1.75

2.00 - 1.75 = .25

Step-by-step explanation:

Answer:

1/8

Step-by-step explanation:

The probability of getting tails on a single flip is 1/2.

Each of the flips is an independent event so you must multiply the probability of getting tails on each flip together.

So, your answer will look like this

[tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] x [tex]\frac{1}{2}[/tex] ; which equals;

1/8

Answer:

1/8

Step-by-step explanation:

To calculate the probability you have to name all possible results first. If you mark a result of a single coin flip as  H  for heads or  T  for tails all results of  3  flips can be written as:

Ω = { ( H , H , H ) , ( H , H , T ) , ( H , T , H) , ( H , T , T ) , ( T , H , H ) , ( T , H , T ) , ( T ,T , H ) , ( T , T , T ) }

Each triplet contains results on  1st,  2 nd and  3 rd coin. So you can see that in total there are  8  elementary events in  Ω.

| Ω |  =  8

Now we have to define event  A  of getting tails three times.

The only elementary event which satisfies this condition is  ( T , T , T )  so we can write that:

A  =  { ( T, T , T ) }

| A |  =  1

Now according to the (classic) definition of probability we can write, that:

P ( A )  =  | A|/  | Ω |  =  1 /8

So finally we can write the answer:

The Probability of getting 3 tails in 3 coin flips is  1 /8 .

Answer:

ur steps would be 9*1*9  = 9^3

Step-by-step explanation:

Any number in the power of 0 = 1

Answer:

9^4

Step-by-step explanation:

Let's review the equation:

9 · 9^0 · 9^3

Anything to the power of 0 is equal to one, so 9^0 is one

That leaves us with 9 · 1 · 9^3

9 · 1 = 9

9^1 · 9^3 = 9^4

so..

9 · 9^3

Out of 5 trials, "at least one failure" = " at most four successess", so the probability you're looking for is
