Given a parallelogram

Theorem: the diagonals of a parallelogram bisects each other

Thus

\begin{gathered} |MP|=|PK| \\ \text{therefore} \\ |MK|=|MP|+|PK| \end{gathered}\begin{gathered} \text{ |MP|=19} \\ \text{thus, |PK|=19} \\ |MK|=19+19=38 \end{gathered}

Hence, the measure of line MK is 38

In this diagram the big square is divided into 7 congruent small squares and two congruent triangles. The area of the shaded squ
Salsk061 [2.6K]
Since each square will have an area of 4 cm^2 because they are congruent, then let’s find the side length of them.

Square root of 4 is two

Each side is 2 cm. Since the unshaded triangle has 3 on the base and height, then it is same to assume that the triangle has a base of 6 cm (2 * 3) and a height of 6 cm.

The formula of the area of a triangle is:
1/2 ( base times height)

Let’s plug in some values

1/2(6 * 6)

Multiply

1/2 (36)

Divide

18

Since the triangles are also congruent, then the shaded side has the same area.

The shaded triangle has an area of 8 cm ^2

If susan, janice, and melvin take 2.0 hours to walk to their school at a rate of 1.0 m/s, how far is their school from their hou
RideAnS [48]

Answer:

7.2 km

Step-by-step explanation:

Given that:

Hours taken = 2 hours

Walk rate = 1 m/s

Distance = Speed * time

Time taken in seconds = 2 * 60 * 60 = 7200 s

Hence,

Distance = 1 m/s * 7200s

Distance = 7200 meters

Distance in km = 7200 / 1000 = 7.2 km

a) The halfway number is \frac{-4.5}{10}.

b) The ascending order is \frac{-1}{2},\frac{-4.5}{10}and \frac{-2}{5}.

<u>Step-by-step explanation:</u>

a)Halfway number is otherwise Middle number.

The halfway number of two numbers = \frac{sum of two numbers}{2}.

The halfway for \frac{-2}{5} and \frac{-2}{5} = \frac{\frac{-2}{5}+ (\frac{-1}{2})}{2}.

=\frac{-2}{5}+ (\frac{-1}{2}).

= \frac{-4-5}{10}.

=\frac{-9}{10}.

∴Halfway =\frac{\frac{-9}{10} }{2}.

=\frac{-4.5}{10}

The halfway for \frac{-2}{5} and \frac{-1}{2}= \frac{-4.5}{10}.

b) The ascending order is \frac{-1}{2},\frac{-4.5}{10}and \frac{-2}{5}.

What is the a, b, and r for y=3.6(1.25)^x
tia_tia [17]

Answer:

a=3.6, v=1.25 and r=25%

Step-by-step explanation:

The given exponential function is

y = 3.6 {(1.25)}^{x}

We compare to the form:

y = a{(b)}^{x}

We have a=3.6, b=1.25

The r is the percentage of increase or decrease.

We realized there is a 25% increase because

y = 3.6 {(1 + 25\%)}^{x}

Hence

r = 25\%
