Answer:

12/25

Step-by-step explanation:

Multiply both the numerator and denominator of each fraction by the number whom makes its denominator equal the LCD.

[tex]\left(\frac{4 \cdot 10}{10 \cdot 10} \right) + \left(\frac{8 \cdot 1}{100 \cdot 1}\right) = \frac{40}{100} + \frac{8}{100}[/tex]

[tex]= \frac{48}{100}[/tex]

Find the new LCD(4).

Answer:

Angle 1= 63°

Angle 2 = 21°

Angle 3 = 96°

The number of steps per mile for a person who is 64 inches tall will be 2354.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Some pedometers have a default setting that assumes that the number of steps a person must take to walk 1-mile decreases by 33 steps per 1-inch increase in height.

Suppose a person 72 inches tall makes 2,250 steps per mile.

70 inches tall makes 2150 steps per 1 mile.

For every inch of height gain, the count of steps required to walk a mile drops by 34.

If the count of steps is S and the height is h, we have the following issue.

S = 2150 - 34(h -70)

Therefore the linear model will be

S = 2150 -34(h - 70)

Now for h = 64, we have

S = 2150 - 34(64 - 70)

S = 2150 - 34 ( -6)

S = 2150 + 204

S = 2354

The number of steps per mile for a person who is 64 inches tall will be 2354.

Answer:

y = 113

Step-by-step explanation:

Two adjacent angles of a parallelogram are always supplementary.

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)

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 )

It is not possible for Jackie to have spent 45 minutes dancing if she runs and dances for a total of exactly 55 minutes and dances for 25 minutes longer than she runs.

These are equations that is made of unknown variables.

Let the time she dances be x

Let the time she runs be y

If Jackie runs and dances for a total of 55 minutes every day, the;

x + y = 55 ............ 1

If She dances for 25 minutes longer than she runs, then;

x = y + 25 ............. 2

The pair of equation are x + y = 55 and x = y + 25

Substitute 2 into 1

y + 25 + y= 55

2y .= 30

y = 15

He spent 15 minutes running everyday

x = 55 - 15

x= 40minutes

Step-by-step explanation:

You have 5^7 over 5^-2.

The 5^-2 on the bottom can be handled by moving the whole thing UP across the fraction bar. This makes the -2 exponent into a positive 2 exponent.

5^7 / 5^-2

= 5^7• 5^2

Answer:

f(-3) = 0

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
