Answer:

1.) the answer is the fourth one, 1/5^7

2.) the answer is the fourth one, 1/5^6

3.) the answer is the fourth one, (2^6)^-5

4.) this is seems to be a duplicate of the first one

Step-by-step explanation:

1.) by 'adding' 4 exponent values on the top it simplifies the top to simply one and 5^7 on the bottom

2.) since this is an exponent of an exponent multiply them, getting 5^-6, then simplify negative exponents.

3.) exponents of exponents are multiplied

Answer:

The probability that both of Eduardo’s partners for the group project will be girls is

Step-by-step explanation:

Given : A hat contains slips of paper with the names of the 26 other students in Eduardo’s class on them, 10 of whom are boys. To determine his partners for the group project, Eduardo has to pull two names out of the hat without replacing them.

To find : What is the probability that both of Eduardo’s partners for the group project will be girls?

Solution :

Total number of students = 26

Number of boys = 10

Number of girls = 26-10=16

Eduardo has to pull two names out of the hat without replacing them.

For the first hat,

Favorable outcome of getting girl = 16

Total number of outcome = 26

For the second hat, without replacement

Favorable outcome of getting another girl = 15

Total number of outcome = 25

The probability that both of Eduardo’s partners for the group project will be girls is

Plssss help me it’s really important!!!

slavikrds [6]

Answer:

Step-by-step explanation:

Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is

6x = x + 2y ( subtract x from both sides )

5x = 2y ( subtract 2y from both sides )

5x - 2y = 0 → (1)

and perimeter = 29, that is

6x x + 2y + 5x - y = 29 , simplifying

12x + y = 29 → (2)

Multiply (2) by 2

24x + 2y = 58 → (3)

Add (1) and (3) term by term to eliminate y, that is

29x = 58 ( divide both sides by 29 )

x = 2

Substitute x = 2 into (2) and evaluate for y

12(2) + y = 29

24 + y = 29 ( subtract 24 from both sides )

y = 5

Thus

FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B

Find the value of x.

Leokris [45]

Answer:

Therefore the value of $x=31\°$

Step-by-step explanation:

Given:

m∠ A = 56°

m∠ B = 75°

m∠ ACD = x°

To Find:

x = ?

Solution:

In Δ ABC

An exterior angle of a triangle is equal to the sum of the opposite interior angles.

Here,

The opposite interior angles are angle A and angle B.

An exterior angle of a triangle is angle ACD which is x°

∴ $m\angle A +m\angle B=m\angle ACD\\$ ...Exterior angle property of Δ

Substituting the values we get

$56+75=x\\\\\therefore x=131\°$

Therefore the value of $x=31\°$
