Help me..it has to be rounded to the tenths
klio [65]

Answer:

10.2 cm²

Step-by-step explanation:

The area (A) of a regular hexagon is

A = \frac{1}{2} × perimeter × apothem

Perimeter = 6 × 2 = 12 cm ( hexagon has 6 sides ), hence

A = 0.5 × 12 × 1.7 = 6 × 1.7 = 10.2 cm²

Find the measurement
xenn [34]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

6z + 7  = 8z - 9

8z - 9 = 6z + 7

Add sides 9

8z - 9 + 9 = 6z + 7 + 9

8z = 6z + 16

Subtract sides 6z

- 6z + 8z =  - 6z + 6z + 16

2z = 16

Divide sides by 2

\frac{2z}{2}  =  \frac{16}{2}  \\

z = 8

Thus ;

NP = 8z - 9

NP = 8(8) - 9

NP = 64 - 9

NP = 64 - 4 - 5

NP = 60 - 5

NP = 55

Done...

Find the percent of increase or decrease? 2.5y to 1.5y
horsena [70]

Answer:

From 2.5 y to 1.5 y there is a 40 % DECREASE in the value.

Step-by-step explanation:

Here, the initial value = 2.5 y

The final value of 1.5 y

Now,as Final Value  < Initial Value

So, there is a DECREASE IN THE VALUE.

Now, decrease in the value  = Initial value  - Final Value  

                                                =  2.5 y = 1.5 y  = 1 y

or, there is a decrease of ( 1 y) in the given value.

Now, Percentage decrease in the value is given as:

\textrm{Percentage Decrease} = \frac{\textrm{The decrease in the value}}{\textrm{The initial Value}} \times 100\\ = \frac{1 y}{2.5 y}  \times 100 = 40

or, Percentage Decrease = 40%

Hence, from 2.5y to 1.5y there is a 40 % DECREASE in the value.
