Answer:
The area of the deck is of 146.14 squared units.
Step-by-step explanation:
Regular hexagon:
A regular hexagon has 6 sides, all with the same measure.
Perimeter of a regular hexagon:
The perimeter of a regular hexagon with side x is given by:
[tex]P_h = 6x[/tex]
Area of a regular hexagon:
The area of a regular hexagon with side x is given by:
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2}[/tex]
It has a perimeter of 45 units.
This means that:
[tex]6x = 45[/tex]
[tex]x = \frac{45}{6}[/tex]
[tex]x = 7.5[/tex]
What is the are of the deck
[tex]A_h = \frac{3\sqrt{3}x^{2}}{2} = \frac{3\sqrt{3}*(7.5)^{2}}{2} = 146.14[/tex]
The area of the deck is of 146.14 squared units.

I need help with this geometry question
Answer:
x=9; JL= 23
Step-by-step explanation:
To find x:
If JL and KM are equivalent, then JL = KM. Substitute the equations and you get 2x+5 = 7x-40.
Put the similar terms on the same side by subtracting 2x from both sides and adding 40 to both sides. You will get 45=5x.
Get x alone by dividing both sides by 5 and you will get 9=x.
To find JL:
Substitute the x in 2x+5 (JL length equation) with 9. Your new equation will be 2(9) + 5.
2•9 = 18.
18+5=23
Please give me the answer. Thanks
If r * s = s to the power of r, then 3 * 2 =
Answer:
[tex]3*2=8[/tex]
Step-by-step explanation:
We know that [tex]r*s=s^{r}[/tex], and we want to find [tex]3*2[/tex] using this formula. To do this, notice that [tex]r=3[/tex] and [tex]s=2[/tex], so all we have to do is substitute the given values into the formula. Therefore:
[tex]r*s=s^{r}[/tex]
[tex]3*2=2^{3}[/tex] (Substitute [tex]r=3[/tex] and [tex]s=2[/tex] into [tex]r*s=s^{r}[/tex])
[tex]=8[/tex] (Simplify)
Hope this helps!

If y=-4+11 and 3x+y=9 what is the value of y?
Answer:
y = 7
x = 2/3
Step-by-step explanation:
hope it help
plz follow me
Answer:
2/3
Step-by-step explanation:
We know the value of y, so substitute y into the equation:
3x + (-4 + 11) = 9 --> remove parentheses
3x - 4 + 11 = 9
3x + 7 = 9 --> subtract 7 from 9
3x = 2 --> divide
x = 2/3

What is the value for each box to make the expressions true?
1: 7(3+5) = ? + ?
2: 15 - 10 = ? (3-2)
Please hurry I have to submit this by 3:00
Answer: 1. 7(3+5)= 21+35
2. 15 - 10 = 5 (3-2)
Step-by-step explanation:
1: 7(3+5) = ? + ?
Opening the bracket and multiplying each number by 7
7 x 3 + 7 x 5 = 21 + 35 =56
7(3+5)= 21+35
2.15 - 10 = ? (3-2)
15- 10 = 5 , On the other hand,
3-2 = 1
to make the left hand equivalent to the right hand side , we multiply the difference gotten from 3-2 by 5 so we have
15 - 10 = 5 (3-2)
5=5(1)
5=5

Julio invest $15,000 in a savings account that pays 1.5% simple interest. How much will be in the
account after 5 years if Julio makes no withdrawals or deposits? *
Answer: Final amount
Step-by-step explanation:
Final amount = Simple interest + Principal
=Principal x Rate x Time + Principal
= Principal (Rate x Time +1) [Simple interest =Principal x Rate x Time]
Given: Principal = $15,000, Rate = 1.5% = 0.015 [To conver % into decimal we divide it by 100]
Time = 5 years
Final amount = $(15000(0.015 ×5+1))
=$ (15000×1.075)
=$ 16125
Hence, there will be $16,125 in the account after 5 years if Julio makes no withdrawals or deposit.

Estimate the time Juanita will arrive at her aunt's home 320 miles away if she leaves at 9:00 a.m., drives about 60 miles per hour, and stops
for a 40 minute break halfway.
A 12:00 p.m.
B. 1:00 p.m.
c. 2:00 p.m.
D. 3:00 p.m.
E. 4:00 p.m.
Answer:
D. 3:00 p.m.
Step-by-step explanation:
d = Distance = 320 miles
s = Speed = [tex]60\ \text{mph}=\dfrac{60}{3600}=\dfrac{1}{60}\ \text{miles/s}[/tex]
Time taken is given by
[tex]t=\dfrac{d}{s}\\\Rightarrow t=\dfrac{320}{\dfrac{1}{60}}\\\Rightarrow t=19200\ \text{s}[/tex]
40 minutes break is [tex]40\times 60=2400\ \text{s}[/tex]
Total time taken is [tex]19200+2400=21600\ \text{s}=\dfrac{21600}{60\times 60}=6\ \text{hours}[/tex].
So, the entire trip took 6 hours. 6 hours after 9 a.m. is 3 p.m.
3. What is the perimeter of a rectangle if the width is 2 ½ inches and the length is 4.5 inches?
(show how you get your answer please)
Answer:
Perimeter of the rectangle = 14 inches
Step-by-step explanation:
Step(i):-
Given length of the rectangle = 4.5 inches
Given that the width of the rectangle = [tex]2\frac{1}{2} = \frac{5}{2} = 2.5[/tex] inches
The area of the rectangle = length × width
= 4.5 × 2.5
= 11.25 sq inches
Step(ii):-
Perimeter of the rectangle = 2( length + width)
= 2( 4.5 + 2.5)
= 14 inches
Final answer:-
Perimeter of the rectangle = 14 inches

If you look at both of the triangles carefully, you will see that both side AB and side DC have the same amount of lines. Since they have the same sides, the angle that they share would equal each other as well. The last side is obviously equal to each other because they are the same.
SSS, because all of the sides are the same ; AC = BD , AB = CD , and they both share side BC
