An isosceles triangle has a perimeter of 46 inches. The base is 6 less than twice each of the congruent legs. What is the sum of the lengths of the two congruent legs?

Answer:

KM

KL

LM

Step-by-step explanation:

The solutions to the equation are x = 5 and x = 3

The equation is given as

|x - 4|= 1

The above equation is an absolute value equation

When the absolute value sign is removed from the equation, we have

x - 4 = 1 or x - 4 = -1

Add 4 to all sides of the equation

So, we have the following equations

x = 1 + 4 or x = 4 - 1

Evaluate

x = 5 or x = 3

This means that the value of the equation is x = 5 or x = 3

Adam's account balance at the end of the month is 19.13 dollars.

The amount present in Adam's bank account at the beginning of the month is $174.85.

The transactions he wrote are,

58.00

-316.35

102.96

The Transactions which have positive sign are credit amount and the transaction with negative sign are debit amount.

We can write,

The balance at the end of the month = Initial balance present + Credit amount + debit amount

So, balance in Adam's account can be found by simple addition and subtraction,

Balance = 174.85 + 58.00 + 102.96 - 316.38

Balance = 335.81 - 316.68

Balance = 19.13

It is shown that if a parallelogram's diagonals are perpendicular, the parallelogram is a rhombus.

A parallelogram is a quadrilateral with two parallel sides (and therefore opposite angles equal).

A rhombus is a quadrilateral with all of its sides equal. Because opposite sides of a parallelogram are equal, a rhombus is a type of parallelogram in which all sides are equal.

We must demonstrate that if the diagonals of a parallelogram are perpendicular, then the parallelogram is a rhombus.

Let ABCD be a  parallelogram .

Consider Δ AOD and Δ COD

Since, a parallelogram's diagonals bisect each other we can say that,

AO = CO

∠AOD = ∠COD = 90°

DO = OD

Δ AOD ≅ Δ COD [SAS rule]

∴ AD = CD

Because the parallelogram's adjacent sides are equal, we can conclude that all four sides are equal.

As a result, it is demonstrated that if the diagonals of a parallelogram are perpendicular, the parallelogram is a rhombus.

The degrees to radians conversion is given as 1° = π/180 radian thus the conversion of 310° is (31/18)π.

To convert any unit into another is called a unit conversion.

In order to convert units, we need to care about their dimensions their dimension should not be changed.

It is known that π radian = 180°.

1° = (π/180) radian.

Multiply both sides by 310

310° = (π/180)310

310° = (31/18)π

The given angles in the figure are 2x + 42° and x - 24°, which are interior angles formed on the same side of the transversal.

By Same Side Interior Angles Theorem,

2x + 42° + x - 24° = 180°

The cost of renting the meeting room by the manager for the hours 1,2,3 and 4 defined by the function of (t) = function of (t-1) + 20, given that function of (1) = 100 is 520.

A function can be defined as a mapping whose co-domain is the set of real numbers.

Given the mapping defined as function of (t) = function of (t-1) + 20, for function of (1) = 100

Hence,

.f (2) = function of (2-1) + 20

.f (1) + 20

100 + 20 = 120

.f (3) = function of (3-1) + 20

.f (2) + 20

120 + 20 = 140

f (4) = f (4-1) + 20

.f (3) + 20

140 + 20 = 160

This can be seen in a table as shown above!

We can conclude with the proper mapping of the defined function of (t) = function of (t-1) + 20 for function of (1) = 100 that the total cost for the hours 1,2,3 and 4 for renting the meeting room is 520.

Answer:

x = 15

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

3x - 5 is an exterior angle of the triangle, then

3x - 5 = x + 25 ( subtract x from both sides )

2x - 5 = 25 ( add 5 to both sides )

2x = 30 ( divide both sides by 2 )

x = 15

Answer:
