Answer:

Step-by-step explanation:

6% of number = 6/100 × x = 6x/100 = 3x/50

Sum of the number and 6% of itself = 42.4

x + (3x/50) = 42.4

(50x+3x)/50 = 42.4

53x = 42.4 × 50

53x = 2120

x = 2120/53

x = 40

Answer:

The answer is x = 40

Step-by-step explanation:

6% of a number is 6/100 * x

Of means multiply.

so 6% of x = 6/100 * x = 6 * x / 100 = 0.06x

Now just put these two together.

x + 0.06x = 42.4 Combine the left

1.06x = 42.4 Divide by 1.06

x = 42.4 / 1.06

x = 40

Find the solution of the given initial value problems in explicit form. Determine the interval where the solutions are defined.

natali 33 [55]

Answer:

The solution of the given initial value problems in explicit form is $y=x-x^2-2$ and the solutions are defined for all real numbers.

Step-by-step explanation:

The given differential equation is

$y'=1-2x$

It can be written as

$\frac{dy}{dx}=1-2x$

Use variable separable method to solve this differential equation.

$dy=(1-2x)dx$

Integrate both the sides.

$\int dy=\int (1-2x)dx$

$y=x-2(\frac{x^2}{2})+C$ $[\because \int x^n=\frac{x^{n+1}}{n+1}]$

$y=x-x^2+C$ ... (1)

It is given that y(1) = -2. Substitute x=1 and y=-2 to find the value of C.

$-2=1-(1)^2+C$

$-2=1-1+C$

$-2=C$

The value of C is -2. Substitute C=-2 in equation (1).

$y=x-x^2-2$

Therefore the solution of the given initial value problems in explicit form is $y=x-x^2-2$ .

The solution is quadratic function, so it is defined for all real values.

Therefore the solutions are defined for all real numbers.

Using the properties of triangles, prove that angle a is congruent to angle c in the drawing below.

ioda

Answer:

There are no triangles given, so I will explain what congruent triangles are.

Step-by-step explanation:

Two triangles are said to be congruent if the three sides and the three angles of both the angles are equal in any sense.

Consider the following conditions for two triangles:

- Two angles and corresponding side, of the two triangles are equal

- Two sides and angle between the two triangles are equal

- Hypotenuse and Leg of two right angled triangles are equal.

If all these conditions are met for any two triangles, they are said to be congruent.

Solve the following equation. Express your answer as an integer, simplified fraction, or decimal rounded to two decimal places.

Andrej [43]

The width of a rectangle is going to be equal on both sides, as they’re parallel in a rectangular shape. We know the width is 86 yards, and we have two lots of these, therefore 86 multiplied by 2 is equal to 172 yards.

We still have two more sides, but once again, because this is a rectangle, those sides must be equal. Therefore if we subtract the 172 yards we know from the total perimeter of 438 yards we will end up with an answer of 266 yards. This figure is divided by two because we have a length on either side of the perimeter. Therefore the answer is 133 yards.

Hope this helps!
