What is 8.57 as a fraction

Answer:

0.01

Step-by-step explanation:

Assuming the deck is the national playing deck with 52 cards.

Your probability of getting a 3 from the entire deck is 4/52. This number is the same for 10.

To get the probability of pulling a 3 and a 10 afterwards, you must multiply these two fractions (you're expecting a lower percentage).

[tex]4/52 * 4/52 = 0.0059[/tex]

Answer:

8

Step-by-step explanation:

Take the length and multiply it by 2. then take your answer and multiply it by the perimeter. Then, take that answer and divide it by 2. Hope this helps :)

Hello.

To find the perimeter of a rectangle, use the formula P = 2(l + w).

Input 39 as l.

94 = 39 + 39 + w + w

Simplify

94 = 78 + 2w

Subtract the two known numbers

94 - 78 = 16

16 = 2w

So that means w = 8.

The width is 8.

Answer:

to the power of 2

for example you can be asked to find the square number of 5 which is the same as 5²= 25

two exterior angles for those angles would be 140 and 85

Answer:

56

Step-by-step explanation:

Answer:

The third one(-20+(n-1)*)

Step-by-step explanation:

It's correct because when you plug in one of the numbers in the list, it makes the equation equal. Example Below.

n=4

n=-20+(n-1)8

4=-20+(4-1)8

4=-20+3*8

4=-20+24

4=4

Answer:

so [tex]2^{8}[/tex] equals 2x2x2x2x2x2x2x2

Step-by-step explanation:

Its that because when expanding Exponents, you always put the first number of the exponet first. like for example, [tex]3^{2}[/tex] , you put the three 2 times and multiply. 3x3

Answer:

complementary

Step-by-step explanation:

Answer:

A = (- 1, 0 ) and B = (4, 0  )

Step-by-step explanation:

Given

y = x² - 3x - 4

To find the x- intercepts, let y = 0, that is

x² - 3x - 4 = 0

Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)

The factors are - 4 and + 1 , since

- 4 × 1 = - 4 and - 4 + 1 = - 3, thus

(x - 4)(x + 1) = 0

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4 ⇒ point B

x + 1 = 0 ⇒ x = - 1 ⇒ point A

Answer:

x = 5

Step-by-step explanation:

There are two possible ways to look at this equation, but each way the answer is the same

first

(3x / 24) = (120 / 192)

solve using cross products

24 * 120 = 3x * 192

2880 = 576 x

/ 576     /576

5 = x

second

(3x / 120) = (24 / 192)

solve using cross products

3x * 192 = 24 * 120

576 x = 2880

/576      /576

x = 5

Answer:

100 people.

Step-by-step explanation:

$4,000 (total budget) - $80 (clean-up fee) = $3,920

$3,920 divided by $39 per person = 100.51

A total of 100 people could be invited for the Neely's to stay within their budget.

The greatest number is 100 people that they may invite and still stay within their budget.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

We have been given that they have budgeted $4,000 for their reception. If the reception hall charges an $80 cleanup fee plus $39 per​ person.

We have to determine the greatest number of people that they may invite and still stay within their budget.

Here total budget = $4,000

And clean-up fee = $80

Apply the subtraction operation,

⇒ 4,000 - 80

⇒ 3,920

We need 3,920 divided by $39 per person for finding the greatest number of people that they may invite.

⇒ 3,920/39

⇒ 100.51

Therefore, the greatest number is 100 people that they may invite and still stay within their budget.

Answer:

1.  Look for factors that each term has in common.

    They all have a "b" so factor that out.

    a2b + 2ab - 8b = b(a2 + 2a - 8)

2.  Factor the remaining polynomial.

     Factors of -8 that add to 2 are 4(-2)

     a2 + 2a - 8 = (a+4)(a-2)

Final answer:  b(a+4)(a-2)

Step-by-step explanation:

Answer:

A = 4N + 5

A + N = 120

Step-by-step explanation:

Given that

A = Number of AFC cars

N = Number of NFC cards

And, Total cards is 120

Now

the equation would be

A + N = 120

Also

The number of AFC is 5 more than 4 times the number of NFC cards

So,

A = 4N + 5

Therefore

A = 4N + 5

A + N = 120

Hence, the system of equations that should be used is A = 4N + 5 and A + N = 120 respectively

Answer:

Step-by-step explanation:

Answer:

a, [tex]Books = 315[/tex]

b, [tex]Total = 20s + 45l[/tex]

Step-by-step explanation:

Given

[tex]Small\ Box = 20[/tex]

[tex]Large\ Box = 45[/tex]

Solving (a): Books using 5 small and 7 large boxes;

This is calculated as follows

[tex]Books = Size * quantity[/tex]

For Small box

[tex]Books = 20 * 5[/tex]

[tex]Books = 100[/tex]

For large box:

[tex]Books = 45 * 7[/tex]

[tex]Books = 315[/tex]

[tex]Total = 100 + 315[/tex]

[tex]Total = 415\ books[/tex]

Solving (b): s small and l large

We use the same concept as (a) above:

For Small Box

[tex]Books = 20 * s[/tex]

[tex]Books = 20s[/tex]

For large box

[tex]Books = 45 * l[/tex]

[tex]Books = 45l[/tex]

[tex]Total = 20s + 45l[/tex]
