(b^7/4^5)^-3=? what is the answer please help

Answer:

√30

Step-by-step explanation:

We can find the value of x by using Euclidean theorem

x^2 = 3 × 10

if x^ = 30 then x = √30

Answer:

Angle 1 and 7

Step-by-step explanation:

(see attached for reference)

In our case, the corresponding angles are:

1,5

2,6

3,7

4,8

If we look at the choices, we can see that "Angle 1 and 7" does not show up in the list above, hence this is 1, 7 are not corresponding angles.

Answer:

C. 1/30

Step-by-step explanation:

From the question, we are told that, there are

Girls = 4

Boys = 6

Total number of children = 10

We are told to find the probability of choosing 3 girls and no boy

To solve for this, we would be using the combination formula

C( n, r) = nCr = n!/r ! (n - r) !

Probability of choosing 3 girls out of 4 = 4C3

Probability of a total of 3 of the team

members = 10C3

The probability of choosing 3 girls and no boy = 4C3 ÷ 10C3

= 4!/3! (4 -3)! ÷ 10!/3! (10 -3)!

= [4! / 3! × 1! ]÷[ 10!/ 3! × 7!]

= [4 × 3 × 2 × 1/ 3 × 2 × 1 × 1 ] ÷ [ 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1/ 3 × 2 × 1 × 7 × 6 × 5 × 4 × 3 × 2 × 1]

= [ 4 ] ÷ [ 720/6]

= 4 ÷ 120

= 1/30

Therefore, the probability that 3 girls and no boys will be selected = 1/30

Answer:

[tex]21[/tex]

Step-by-step explanation:

Let [tex]x[/tex] be that number.

[tex]12x-216=2x-6[/tex]

[tex]12x-2x=-6+216[/tex]

[tex]10x=210[/tex]

[tex]10x/10=210/10[/tex]

[tex]x=21[/tex]

21 is the number.

Let n, equal that number.

12n - 216 = 2n - 6

Solve for n:

12n - 216 = 2n - 6

12n - 216 + 216 = 2n - 6 + 216

12n = 2n + 210

12n - 2n = 2n - 2n + 210

10n = 210

10n/10 = 210/10

n = 21

Therefore, the answer si 21.

Best of Luck!

Answer:

B. [tex]y=-\frac{1}{3}x+5[/tex]

Step-by-step explanation:

Answer:

w = 17 fts

l = 32 fts

Step-by-step explanation:

P = 2w + 2l

l = 2w - 2

98 = 2w + 2(2w - 2)

98 = 2w + 4w - 4

98 + 4 = 6w

6w = 102

w = 17 fts

l = 2×17 - 2 = 34 - 2 = 32 fts

Answer:

Answer:

x=5

x=−5

Step-by-step explanation:

x^2−25=0

Consider x^2 −25.

Rewrite x^2−25 as x^2−5 ^2

The difference of squares can be factored using the rule:

a^2−b^2 =(a−b)(a+b).

(x−5)(x+5)=0

To find equation solutions, solve x−5=0 and x+5=0.

x=5

x=−5

Answer:

Show one example of his claim, adding two odd numbers to form an even number

Answer:

C.

Step-by-step explanation:

You cannot prove his conjecture by an example. You must create two generic odd numbers using algebraic expressions. Then you add the two expressions and show that the sum is even.

Answer: C.

Answer:

There are 36 total possible outcomes.

Rolling a sum of 11 or higher, there are 3 possible rolls, to make a 3/36 = 1/12 probability.

Rolling a sum of 4 there are also 3 possibilities, so the chance would be the same.

Rolling a sum of 9, there are 4 possibilities, which is a better chance.

Rolling a sum less than 5, there is 6 possibilities, which is a better chance.

Rolling greater than 5 but less than 7 means rolling a sum of 6, there are 5 chances, which is a better chance.

Rolling greater than 9 but less than 11, means rolling a 10, there are 3 possibilities, which is the same.

Rolling greater than 2 and less than 4 means rolling a 3, there are 2 possibilities, which is less.

The answers would be:

Rolling a sum of 9,

Rolling a sum less than 5

Rolling greater than 5 but less than 7

Answer:

There are 36 total

Answer:

42

Step-by-step explanation:

2 2/3 divided by 1/3 = 7 length

1 divided by 1/3 = 3 width

2/3 divided by 1/3 = 2 height

7 x 3 x 2 =  42  (1/3cm cubes)

Answer:

4000 N

Step-by-step explanation:

this question should be in physics actually

m = 1200 kg

initial velocity = vo = 15 m/s

final velocity = vt = 0 because it stops

time needed = t = 4.5

so we can find the Force F by these step

first find deacceleration

vt = vo + at

0 = 15 + a(4.5)

15 = -4.5a

a = - 15/4.5 = - 10/3 = - 3.33 m/s²

F = m.a = 1200 . 10/3 = 4000 N

Answer:

h =15

Step-by-step explanation:

6:h   is 8:20

Divide the right rate by 4

          8/4:20/4

           2 :5

Now multiply by 3

          2*3 : 5*3

            6 : 15

h = 15

Answer:

h=15

Step-by-step explanation:

6     8

_     _

h     20

6*20 is 120

8*h is 8h

120/8 is 15

Answer:

15 cm

Step-by-step explanation:

Area of a rectangle formula: A = lw

Simply plug in known variables and solve:

60 = 4(w)

w = 15

Answer:

15 cm

Step-by-step explanation:

If we know the area which is 60 and the width which is 4 we can just divide 60 by 4 and we get 15cm

Answer:because it can be rewritten as a quadratic equation with u substitution

Step-by-step explanation:

Answer:

The correct options ares:

b) y = -2sin2x

c) y = -2cos(2 x - π/2)

d) y = 2sin2( x - π/2)

Step-by-step explanation:

As we can see in the graph, when x = 0 then y = 0.

Simply substitute x=0 in each equation.

a) y = 2cos2(x • π/2)

for (0,0)

y = 2

False

b) y = -2sin2x

for (0,0)

y=0

True

c) y = -2cos(2 x - π/2)

for (0,0)

y=0

True

d) y = 2sin2( x - π/2)

for (0,0)

y=0

True,

(We can also find the solution by using y= Asin(Bx+C) and y = Acos(Bx+C), we'll find that except equation a, all other equations have same amplitude, horizontal shift, period and vertical shift)

Answer:

The answer is 3√5 mi.

The formula is: d = √(3h/2)

Wyatt:

h = 120 ft

d = √(3 * 120/2) = √180 = √(36 * 5) = √36 * √5 = 6√5 mi

Shawn:

h = 270 ft

d = √(3 * 270/2) = √405 = √(81 * 5) = √81 * √5 = 9√5 mi

How much farther can Shawn see to the horizon?

Shawn - Wyatt = 9√5 - 6√5 = 3√5 mi

someone has already answered this, so here you go :

Answer:

the correct answer is A. (-3, -2)

Answer:

The value of the expression given is:

Step-by-step explanation:

First, you must divide the expression in three, and to the final, you can multiply it:

Now, we can solve each part one by one:

First part.

And we elevate this to -2:

Second part.

And we elevate this to 4:

Third Part.

At last, we multiply all the results obtained:

We approximate the value because the difference to 4 is minimal, which could be obtained if we use all the decimals in each result.
