Answer:

Susan has a total of 660 nails

Step-by-step explanation:

John box contains 65 small nails, 40 medium nails, and 45 large nails.

The proportion of John nails is

65/5:40/5:45/5

13:8:9

Total = 30

If Susan has 176 medium nails and same proportion to John's nails

8/30(x) = 176

Where x is the total number of nails for Susan box

X= (176*30)/8

X= 22*30

X= 660 nails

Susan has a total of 660 nails

Step-by-step explanation:

In order to solve this question we use ratio and proportion

Step-by-step explanation:

Just keep simplifying 8/12 until you end up with 2/3

Find the GCF of both the numerator and denominator and you end up with 2/3

Just to make it clear 8/12 = 2/3

Answer:

the answer is pythagoras thorium

Answer:

Step-by-step explanation:

Given Tyler test grades to be 77%, 62% 85% and 80%, to find its average in the class, we will find the mean of his grades.

Mean is the ratio of the sum of the grades to the total number of grades given.

[tex]mean (\overline x) = \frac{\sum Xi}{N}[/tex]

Xi are the individual grades

N is the total number of grades = 4

[tex]\overline x = \dfrac{77+62+85+80}{4} \\\overline x = \frac{304}{4}\\ \overline x = 76 % \\[/tex]

Hence his average in the class is 76%

Answer:

x= 3.89 x 7.9

Step-by-step explanation:

x= 3.89 x 7.9

x=30.731

Answer: (8)($4)

Answer with an explanation:

What we need to know: Any number 5 or higher is automatically rounded up, any number 4 or lower is automatically round down. Also if the number is after the decimal you can say 5 or higher with a zero because it doesnt do anything to the number, so you could say .50 or higher or .40 or lower and if it has three decimal places just add another zero so it would be .500 higher or .400 lower.

So, 7.9 is rounded up to 8.0 because 9 is 5 or higher.

$3.89 is rounded up to $4.00 because .89 is higher than .50.

Now just take off the zeros from 8.0 and $4.00 to get (8)($4)

Hope this helps.

Answer:

Step-by-step explanation:

1)

a) x-y = 0

Reflexive :

x-x=0, where x and 0 are whole numbers is valid for all x

In this way, x-x is a number

Which infers that (x,x) ∈ R

In this way, R is reflexive

Symmetric :-

(x-y) is a whole number

Which infers - (x-y) is likewise a whole number

Which infers (y-x) is a number

In this way, (x-y) is a number infers that (y-x) is likewise a whole number

i.e If (x,y)∈R at that point (y,x)∈R

In this way, R is Symmetric.

Against Symmetric:-

(x,y)∈R

x-y=0, where x and y are whole numbers

Which infers x=y

Assume, (y,x)∈R

y-x=0, where x and y are whole numbers

Which infers y=x

Consequently, (x-y) is a whole number suggests (y-x) is additionally a whole number

for example In the event that (x,y)∈R at that point (y,x)∈R, where x=y

R is Anti-Symmetric.

Transitive:-

Given,

(x-y)∈R and (y-z)∈R - (I)

To demonstrate that,

(x,z)∈R

from (I)

x-y= 0 and y-z=0

Including both, we get

(x-y)+(y-z)=0

x-z=0

Consequently demonstrated that (x,y)∈R and (y,z)∈R infers that (x,z)∈R

Since the above connection is symmetric, reflexive advertisement transitive. Consequently, it is an identicalness connection.

b) x=|y|

Reflexive:-

x isn't reflexive.

Since for - 2

- 2 ≠|-2|, where - 2 is a whole number.

- 2≠|2|

Consequently, (x,x) isn't Reflexive.

Symmetric:-

(x,y)∈R, infers

x=|y|, where x and y are whole numbers ...(i)

Let x =-2 and y= - 2

- 2≠|-2|

- 2≠|2|

Which infers (x,y) itself doesn't have a place with R.

Consequently R isn't symmetric.

Against Symmetric:-

(x,y)∈R, suggests

x=|y|, where x and y are numbers

let x= - 2 and y =-2

- 2 ≠ |-2|

- 2≠|2|

R isn't hostile to symmetric.

Transitive:-

x=|y| and y=|z| ∈ R

let x=2, y=-2 and z= 2

infers that

2=|-2| and - 2≠|2|

for example 2=|2| and - 2∉|2|

In this way, R isn't transitive.

c) x+y is odd

Reflexive:-

x+x is even, where x is a whole number.

In this way, (x,x)∉R.

R isn't Reflexive.

Symmetric:-

(x,y)∈R

x+y is odd, where x and y are whole numbers

Additionally, (y,x) is odd

infers that y+x is additionally odd

In this way, (y,x)∈R

R is Symmetric.

Against Symmetric:-

(x,y)∈R

infers x+y is odd, where x and y are whole numbers

infers that y+x is additionally odd

In this way, (y,x)∈R

R is Anti-Symmetric.

Transitive:-

Given,

(x,y)∈R and (y,z)∈R, where x,y and z are whole numbers ...(i)

To demonstrate that

(x,z)∈ R

from (I)

x+y is odd and y+z is odd''

Including both we get

x+2y+z is odd

which infers (x,z)∉R

In this way, R isn't transitive.

2) x-y=0 is reflexive, symmetric and transitive in this way it is an equality connection.

while x=|y| and x+y is odd are not equality relations.

Answer:

x = 8 or -4

Step-by-step explanation:

6(x - 2)² + 7 = 223

PEMDAS

expand (x - 2)² first using FOIL

(x - 2)(x - 2)

x² - 2x - 2x + 4

x² - 4x + 4

rewrite equation

6(x² - 4x + 4) + 7 = 223

distribute the 6 through the parentheses

6x² - 24x + 24

rewrite equation

6x² - 24x + 24 + 7 = 223

combine like terms

6x² - 24x + 31 = 223

subtract both sides by 223

6x² - 24x - 192 = 0

divide both sides by 6

x² - 4x - 32 = 0

factor with factoring X

x² - 8x + 4x - 32 = 0

factor by grouping

(x² - 8x) + (4x - 32) = 0

x(x - 8) +4 (x - 8) = 0

(x - 8)(x + 4) = 0

x = 8 or -4

Answer:

32 Blocks of Butter

Explanation:

Since the chef is starting with 8, and I'm guessing they are cutting all the blocks of butter into fourths; this is a multiplication equation. 8×4=32

Answer:

[tex]\huge\boxed{32\ blocks\ of\ butter}[/tex]

Step-by-step explanation:

The chef had = 8 blocks

She cuts/ divides the blocks into fourths.

The chef has now:

=> [tex]8 / \frac{1}{4}[/tex]

=> [tex]8 * 4[/tex]

=> 32 blocks of butter

Answer:

Option A

Step-by-step explanation:

Margot preformed a refection. A reflection is a rigid transformation.

A rigid transformation does not change the size nor the shape of the figure. Rigid transformations only change the position of the shape.

The parallel lines stay 4 centimetres apart after the transformation.

Answer:

I answered the 1st one on your other post

2nd: 1/8

3rd: I don't know anything about inchwe study in cm so I don't know the answer

Step-by-step explanation:

we throw a coin. it has 2 probabilities: heads or tails

each probability is 1/2

1st throw 1/2

2nd throw 1/2

3rd throw 1/2

as all these throws are independent from one another, we put × between them. so: 1/2 ×1/2 ×1/2= 1/8

Answer:

[tex]P(System) = 0.73304[/tex]

Step-by-step explanation:

Given

Reliability of:

A = 0.98

B = 0.85

C = 0.88

Required

Determine the overall reliability

The overall system reliability is calculated by multiplying the individual reliability of each subsystems;

i.e.

[tex]P(System) = P(A) * P(B) * P(C)[/tex]

[tex]P(System) = 0.98 * 0.85 * 0.88[/tex]

[tex]P(System) = 0.73304[/tex]

Hence, the overall reliability is  0.73304

Answer:

120 minutes

Step-by-step explanation:

The lowest number that all three trains times can evenly go into is 120.  60 is not divisible by 8, but 120 is.  So is 12 and 10, so 120.

Answer:

[tex]x < 2 \frac{2}{3} [/tex]

Step-by-step explanation:

The symbol for greater than is '>'.

-3x +6 > -2

Bring constants to one side:

-3x > -6 -2

Simplify:

-3x > -8

Divide both sides by -1, change sign:

3x < 8

Divide by 3 on both sides:

[tex]x < \frac{8}{3} \\ x < 2 \frac{2}{3} [/tex]

Step-by-step explanation:

Hey there!

Well to solve the given,

2y - y + 7 - 1 + 3 + 7x^2 - 4y

We need to combine like terms

[tex]2y - y + 7 - 1 + 3 + 7x^2 - 4y\\7x^2 - 3y + 9\\[/tex]

Hope this helps :)

Answer:

7x^2 - 3y + 9

Step-by-step explanation:

   2y - y + 7 - 1 + 3 + 7x^2 - 4y          [Combine like terms]

= (2y - y - 4y) + (7- 1 + 3) + 7x^2

= -3y + 9 + 7x^2                 [Order the terms from most exponents to least]

= 7x^2 - 3y + 9
