Answer:
94.05 units is the perimeter of this pentagon.
Length of each side in pentagon: 2r × Sin(180/n)
where r is radius and n is number of sides
Using the formula: 2r × Sin(180/n)
: 2*16 * sin(180/5)
: 18.8 units
Perimeter = 5(18.8) units........5 as we know pentagon has 5 sides
= 94.05 units
a coach drives 200 miles at a speed of 40mph how long does the journey take
Step-by-step explanation:
V=d/t; where;
V: speed (miles per hour)
d: distance (miles)
t: time (hour)
t=d/V=200/40=5 hours=300 min= 18 000 sec.
Answer:
the journey takes 5 hours
Step-by-step explanation:
time taken = distance / time taken
= 200 / 40
= 5 hours

The equation of line t is y=1/7x-2
Parallel to line t is line u, which passes through the point (7,6). What is the equation of line u?
The equation of a line u parallel to given equation of a line is y=1/7 x + 5.
Given that, the equation of line t is y=1/7 x-2.
What is slope of a line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
We know that, standard form of equation of a line is y=mx+c
Now, compare y=1/7 x-2 with y=mx+c, we get m=1/7
The slope of a line parallel to given line is m1=m2
So, slope of a parallel line is m=1/7
Put m=1/7 and (x, y)=(7, 6) in y=mx+c, we get
6=1/7 (7)+c
⇒ c=5
Substitute m=1/7 and c=5 in y=mx+c, that is
y=1/7 x + 5
Therefore, the equation of a line u parallel to given equation of a line is y=1/7 x + 5.

Find the 52nd term of the arithmetic sequence -3,12,27
Step-by-step explanation:
first term(a)=3
common difference(d)=t2-a
=12-3
=9
now,
T52=a+(n-1)*d
=3+(52-1)*9
=462
Therefore,the 52nd term of the arithmetic sequence is 462.
The 52nd term of the arithmetic sequence -3, 12, 27, will be 762.
What is an arithmetic sequence?Let a₁ be the first term and d be a common difference.
Then the nth term of the arithmetic sequence is given as,
aₙ = a₁ + (n - 1)d
The arithmetic sequence is given below.
-3, 12, 27, ...
The first term of the arithmetic sequence is negative 3. And the common difference of the arithmetic sequence is given as,
d = 12 - (-3)
d = 12 + 3
d = 15
The equation is given as,
aₙ = -3 + (n - 1) × 15
aₙ = -3 + 15n - 15
aₙ = - 18 + 15n
The 52nd term of the arithmetic sequence -3, 12, 27, will be given as,
a₅₂ = - 18 + 15 × 52
a₅₂ = - 18 + 780
a₅₂ = 762
The 52nd term of the arithmetic sequence -3, 12, 27, will be 762.

Brett paid $229 for 8 tickets to a baseball game, which includes the $13 service fee applied to every order. How much will Brett spend for 15 tickets?
Answer:
$418
Step-by-step explanation:
So first we need to find how much a single ticket will cost.
Subtract the service fee to get how much it cost for 8 tickets.
229-13=216
Then divide that number by 8 to find how much a single ticket costs.
216÷8=27
1 ticket costs $27.
Multiply that by 15 to get how much 15 tickets cost.
27×15=405
Then add back the service fee.
405+13=418

Answer: J
Step-by-step explanation: hope its correct
Hi!
The answer to your question would be J
Here's the math to prove it:
Step 1) You need to add all of the number of tiles together.
9+7+3+6=25
Step 2) You need to take each of your tile numbers and divide them by 25.
9/25=0.36 So F would be true
7/25=0.28 So G would be true
6/25=0.24 So H would be true
3/25=0.12 So J would be not true.

What is the solution to the system of equations?
3x - 6y = -12
x - 2y = -8
(a) Use the substitution method to justify that the given system of equations has no solution.
(a) What do you know about the two lines in this system of equations?
Answer:
(a) Proof explained below
(b) The two lines are parallel
Step-by-step explanation:
(a) In the second equation express [tex]x[/tex] in terms of [tex]y[/tex] to get:
[tex]x=2y-8[/tex]
Then, substitute [tex]x[/tex] for [tex]2y-8[/tex] in the first equation to get:
[tex]3(2y-8)-6y=-12[/tex]
Open parentheses using the distributive property ([tex]a(b-c)=ab-ac[/tex]) which results in:
[tex]6y-24-6y=-12[/tex]
Combine like terms to reach:
[tex]-24=-12[/tex], which is not true. Therefore, for any values of [tex]x[/tex] and [tex]y[/tex], the systems of equations will have no solutions.
Since the two lines have no solutions, that means that they are parallel.
