Step-by-step explanation:

If the triangles are congruent, then angle K will be the same as angle N

The triangles are congruent and the measures of angle  ∠K ≅ ∠N

Transformations change the size or position of shapes. Congruent shapes are identical, but may be reflected, rotated or translated. Scale factors can increase or decrease the size of a shape. Congruent Triangles simply mean the triangles that possess the same size and shape

The three sides are equal (SSS: side, side, side)

Two angles are the same and a corresponding side is the same (ASA: angle, side, angle)

Two sides are equal and the angle between the two sides is equal (SAS: side, angle, side)

A right angle, the hypotenuse and a corresponding side are equal (RHS, right angle, hypotenuse, side)

Given data ,

Let the first triangle be ΔJKL

Let the second triangle be ΔMNP

Now , the triangles are congruent

So , ΔJKL ≅ ΔMNP ( given )

And , Congruent Triangles simply mean the triangles that possess the same size and shape

The three sides are equal (SSS: side, side, side)

So , the measures of angles are also similar

Hence , the angles are similar ( ∠K ≅ ∠N )

The number of minutes Fred takes to spell check 4 pages will be around 26 minutes.

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given that,

Spell check 5 pages   ⇔  In 32 minutes

Divide by 5 ;

Spell check 1 page   ⇔  In 32/5 minutes.

Multiply by 4 ;

Spell check 1 × 4 pages   ⇔ In (32/5) × 4 minutes

Spell check 1 × 4 pages   ⇔ In 25.6 ≈ 26 minutes.

Hence Spell will take around 26 minutes to spell check 4 pages.

given triangle is a right- angled triangle.

from the triangle,

cost 30 =

The number of customer you expect to pay with a credit card will be 51 customers.

Binomial distributions consist of n independent Bernoulli trials.

The expected value will be

E(X) = np

Ian owns a small business selling used books.

He knows that in the last week 122 customers paid cash, 14 customers used a debit card, and 4 customers used a credit card.

If next week, he is expecting 1800 customers.

Then the number of the customer you expect to pay with a credit card will be

n = 1800

The probability of the customer who pays with a credit card will be

p = 4/140

p = 0.02587

Then the expected value will be

E(x) = 1800 x 0.02587

E(x) = 51.42

Explanation:

[tex]\sf Half \ Life : A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]

where A is final amount, Ao is initial amount, t is time taken, h is half life

Here given:

initial amount: 400 millicuries

final amount: 3.125 millicuries

half life: 8 days

time taken: ?

Hence solve for time taken:

[tex]\sf \rightarrow A = A_O \ x \ (\dfrac{1}{2} )^{\dfrac{t}{h} }[/tex]

insert values given

[tex]\sf \rightarrow 3.125 = 400 \ x \ (\dfrac{1}{2} )^{\dfrac{t}{8} }[/tex]

divide both sides by 400

[tex]\sf \rightarrow (\dfrac{1}{2})^{\dfrac{t}{8}}=0.0078125[/tex]

apply exponent rule

[tex]\sf \rightarrow {\dfrac{t}{8}}=\dfrac{ln(0.0078125)}{ln(1/2)}[/tex]

Step-by-step explanation:

The question is asking you to evaluate the function when x = -3. Therefore, substitute -3 in for x and simplify.

f(x) = x² + 7x + 12                            <---- Original equation

f(-3) = (-3)² + 7(-3) + 12                    <---- Substitute -3 for x

f(-3) = 9 + 7(-3) + 12                         <---- Square -3

f(-3) = 9 - 21 + 12                             <---- Multiply 7 x -3

Given equations:

To find :

Put value of y of second equation (i.e y = 4x) in equation one (i.e x + y = 15)

➞ x + y = 15

➞ x + 4x = 15

➞ 5x = 15

Divide both LHS and RHS by 5

➞ (5x)/5 = 15/5

➞ x/1 = 3/1

➞ x = 3

Now put value of x in equation 2

{Note : value of x can be inserted both in equation 1 and 2}

➞ y = 4x

➞ y = 4 × 3

➞y = 12

Verification :

put value of x and y in equation 1 :

LHS = RHS

hence verified !

put value of x and y in equation 2 :

LHS = RHS

hence verified !

∴ Value of x and y is 3 and 12 respectedly .

REQUIRED ANSWER :

(x , y) = (3 , 12)

Answer:

(3, 12)

Step-by-step explanation:

Given equations:

Substitute Equation 2 into Equation 1 and solve for x:

⇒ x + 4x = 15

⇒ 5x = 15

⇒ x = 15 ÷ 5

⇒ x = 3

Substitute the found value of x into Equation 2 and solve for y:

⇒ y = 4(3)

⇒ y = 12

Therefore, the solution of the system is (3, 12)
