Perimeter of a triangle formula:
P = a + b + c
1)
P = x + 6 + 3x + 2 + 2x + 4
P = 6x + 12
2)
P = 6x + 4 + 7x + 1 + 5x + 7
P = 18x + 12
3)
P = 4x - 3 + 3x + 5x - 6
P = 12x - 9
4)
P = 6x - 8 + 3x + 7 + 5x - 3
P = 14x - 4

The exact circumference of a circle is 34π meters. What is the approximate area of the circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
A = 907.46 [tex]m^{2}[/tex]
Step-by-step explanation:
C = πd
34π = πd
d = 34
r = 17
A = [tex]\pi r^{2}[/tex] = 3.14([tex]17^{2}[/tex]) = 3.14(289) = 907.46 [tex]m^{2}[/tex]

A. Skewed Right
B. Uniform
C. Skewed Left
D. Normal
Skewed Right I think. I'm not sure but try it
Answer:
C. Skewed Left
Step-by-step explanation:
Because the first 2 age group have minimal runners than the next 3 age groups spikes and the last 4 are very low once again. the spike occurs relavity near the beggining so if graphed it would be skewed left.

Step-by-step explanation:
Use the following explicit function to identify f(1) & r, and list the first five terms of the sequence.
f(n) = 1000(1/4)^n-1
f(1) =?
r = ?
then the 5 terms:
___, ___, ___, ___, ___...
Given:
The explicit function is:
[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex]
To find:
[tex]f(1)=?,r=?[/tex] and first 5 terms.
Solution:
The explicit formula a geometric sequence is:
[tex]f(n)=ar^{n-1}[/tex] ...(i)
Where, a is the first term and r is the common ratio.
We have,
[tex]f(n)=1000\left(\dfrac{1}{4}\right)^{n-1}[/tex] ...(ii)
On comparing (i) and (ii), we get
[tex]a=1000[/tex]
[tex]f(1)=1000[/tex]
And,
[tex]r=\dfrac{1}{4}[/tex]
For [tex]n=1[/tex],
[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{1-1}[/tex]
[tex]f(1)=1000\left(\dfrac{1}{4}\right)^{0}[/tex]
[tex]f(1)=1000(1)[/tex]
[tex]f(1)=1000[/tex]
For [tex]n=2[/tex],
[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{2-1}[/tex]
[tex]f(2)=1000\left(\dfrac{1}{4}\right)^{1}[/tex]
[tex]f(2)=1000\times \dfrac{1}{4}[/tex]
[tex]f(2)=250[/tex]
Similarly, substituting [tex]n=3,4,5[/tex], we get
[tex]f(3)=62.5[/tex]
[tex]f(4)=15.625[/tex]
[tex]f(5)=3.90625[/tex]
Therefore, [tex]f(1)=1000,r=\dfrac{1}{4}[/tex] and the first five terms are [tex]1000,250,62.5,15.625,3.90625[/tex].
Given:
The explicit function is:
To find:
and first 5 terms.

The explicit formula a geometric sequence is:
...(i)

What is the equation of the given line?
Answer:
y = 1
Step-by-step explanation:
Since the line is horizontal, that means there's no slope (y = b)
Since the line hits the y-axis of 1, the answer is y = 1

Indicate the equation of the given line in standard form.
The line that contains the point Q( 1, -2) and is parallel to the line whose equation is
y - 4 = 2/3 (x - 3)
Answer:
The equation of the line is;
3y = 2x-8
Step-by-step explanation:
Firstly, we need the to get the slope of the given line
To do this, we will write the equation of the line in the standard form
the standard form
is;
y = mx + b
where m is the slope and b is the y-intercept
y -4 = 2/3(x-3)
y -4 = 2x/3 - 2
y = 2x/3 -2 + 4
y = 2x/3 + 2
with respect to the given equation, the slope of the line is 2/3
Mathematically, when two lines are parallel, the slopes of the line are equal
So now, we want to find the equation of the line that has a slope of 2/3 and passes through the point (1,-2)
so;
y = 2x/3 + b
So substitute the values of (1,-2)
1 for x and -2 for y
-2 = 2/3(1) + b
-2 = 2/3 + b
b = -2 - 2/3
b = (-6-2)/3 = -8/3
So the equation of that line is;
y = 2/3x - 8/3
Multiply through by 3
3y = 2x - 8

Answer:
A
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Claire is working two summer jobs, making $7 per hour washing cars and making $15 per hour clearing tables. In a given week, she can work at most 9 total hours and must earn a minimum of $90. If xx represents the number of hours washing cars and yy represents the number of hours clearing tables, write and solve a system of inequalities graphically and determine one possible solution.
Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.
Since Claire is working two summer jobs, making $ 7 per hour washing cars and making $ 15 per hour clearing tables, and in a given week, she can work at most 9 total hours and must earn a minimum of $ 90, to determine one possible solution the following calculation must be performed:
15 x 9 = 135 135 - 90 = 45 45/7 = 6.42 6 x 7 + 3 x 15 = 42 + 45 = 87 5 x 7 + 4 x 15 = 35 + 60 = 95
Therefore, at a minimum, Claire must work 4 hours cleaning tables and 5 hours washing cars to earn more than $ 90.

Answer:
63 degrees
Step-by-step explanation:
Since this is an isosceles triangle, the two bottom angles must be equal, while the top angle (in the way this specific triangle is oriented) must be different. Therefore, angle CDB is 63 degrees.
Answer:
∠CDB = 63°
Step-by-step explanation:
∠CBD and ∠CDB opposite side lengths are congruent (indicated by the little markings)
Because their opposite sides are congruent they are too congruent
So ∠CBD = ∠CDB
because ∠CBD = 63° ∠CDB also equal 63°
Tamekia and Marsha mow lawns during the summer to earn money. Tamekia determined that she can earn between $6.00 and $6.25 per hour. Marsha estimates that she earns between $7.50 and $8.00 per hour. About how much more money will Marsha earn than Tamekia if they each work 22 hours?
Answer:
$33 - $38.50
Step-by-step explanation:
Tamekia $6.00 - $6.25
y = mx
y = (22)(6) = 132
y = (22)(6.25) = 137.50
$132 - $137.50
Marsha $7.50 - $8.00
y = (22)(7.5) = 165
y = (22)(8) = 176
$165 - $176

Lia has a ribbon 325 4/5m long. She cuts off a 150 3/5m long piece; then she divided the rest of the ribbon into 3 parts of equal length. Find the length of each part.
Answer:
Each part is 56 11/15 m long.
Step-by-step explanation:
325 4/5 - 150 3/5
= 170 1/5
170 1/5 = 851/5
851/5 / 3
= 851/5 * 1/3
= 851/15
= 56 11/15.

Use the distance formula to find the distance between each PowerPoint round to the nearest 10th if necessary
Answer:
Step-by-step explanation:
Distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the formula,
Distance = [tex]\sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
a). A(-6, -4), B(-3, -1)
Distance between A and B = [tex]\sqrt{(-6+3)^2+(-4+1)^2}[/tex]
= [tex]\sqrt{9+9}[/tex]
= 3√2
= 4.2 units
b). C(3.5, 1), D(-4, 2.5)
Distance between C and D = [tex]\sqrt{(3.5+4)^2+(1-2.5)^2}[/tex]
= [tex]\sqrt{58.5}[/tex]
= 7.65
≈ 7.7 units
c). Distance between X(5, -5) and Y(-5, 5)
Distance = [tex]\sqrt{(5+5)^2+(-5-5)^2}[/tex]

Ariel is making bracelets. She bought a 15% foot long string, and a 1243 foot long string. If each
bracelet requires 42 of a foot of string, how many bracelets can Ariel make?
Answer:
She can make 55 bracelets
Step-by-step explanation:
We have the correct question as follows;
Ariel bought a 15 1/6 foot long string, and a 12 1/3 foot long string. If each bracelet requires 1/2 of a foot long string, how many bracelets can Ariel make
we have the solution as follows
Firstly, we need to find the total length of the strings bought
We can get this by adding what was bought
That would be;
15 1/6 + 12 1/3
= 91/6 + 37/3
= (91 + 74)/6 = 27 1/2 ft
From the question, each bracelet requires 1/2 ft long
so the number of 1/2 ft long bracelets we can find will be;
27 1/2 divided by 1/2
= 55/2 * 2/1
= 55

A line with a slope of 5 passes through the point (1,9). What is its equation in slope-intercept form? Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = 5x + 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, then
y = 5x + c ← is the partial equation
To find c substitute (1, 9) into the partial equation
9 = 5 + c ⇒ c = 9 - 5 = 4
y = 5x + 4 ← equation of line
