The value of angle 'a' will be 40° for the given polygon.
What is a polygon?A polygon is a closed polygonal chain made up of a finite number of straight line segments and is a type of plane figure in geometry. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.
Given that the polygon has three sides and the two angles are 56° and 84°. The value of the third angle will be calculated as:-
Angle ∠ a = 180 - 84 - 56
Angle ∠ a = 40°
Hence, the value of the angle 'a' is 40°.

Laura has to three cats: The ratio of Socks weight to princess weight is 4:5 The ratio of princesses weight to Luna's weight is 6 :7. What is the ratio of socks weight to Luna's weight?
Answer:
s : l = 24 : 35
Step-by-step explanation:
Let
Socks weight = s
Princess weight = p
Luna's weight = l
The ratio of Socks weight to princess weight is 4:5
s : p = 4 : 5
s / p = 4 / 5
The ratio of princesses weight to Luna's weight is 6 :7
p : l = 6 : 7
p / l = 6 / 7
What is the ratio of socks weight to Luna's weight
Multiply both given ratios
s / p * p / l = 4 / 5 * 6 / 7
p cancel out
s / l = 24 / 35
s : l = 24 : 35
Ratio of socks weight to Luna's weight is 24 : 35

In the figure above, lls, m 3 = (3x-105)º and
mz6=(2x+10)°
What is the m<8?
A. 55°
B. 60°
C. 120°
D. 125°
Answer:
a
Step-by-step explanation:
first step is to set up an equation : 3x-105+2x+10=180
second step is to add like terms : 5x-95=180
third step is to add 95 to both sides: 5x=275
last step is divide 275 ( 180 + 95 ) by 5
A line passes through the points (–2, 1) and (–4, –7). What is the slope of the line?
The slope that passes through the points (–2, 1) and (–4, –7) is 4.
The slope formula can be represented below:
m = y₂ - y₁ / x₂ - x₁Therefore, the slope that passes through the points (–2, 1) and (–4, –7) can be found below
m = - 7 - 1 / -4 - (-2)
m = - 8 / -4 + 2
m = -8 / -2
m = 4.
Therefore, the slope is 4.

A rectangular swimming pool has a volume of 1750 ft.³ water is being added to the pool at a rate of about 20 ft.³ per minute. use an equation in point slope form to determine about how long will it take to fill the pool completely if there were already 1125 gallons of water in the pool use the fact that one cubic foot of space holds about 7.5 gallons of water round the answer to the nearest integer if necessary
Answer:
You have a rectangular pool 15 X 30 X 5 feet
The floor of the pool is 15X30 = 450 ft2
Two sides are 5X15 = 2(75) = 150 ft2
Two sides are 5X30 = 2(150) = 300 ft2
Total area to be painted: 900 ft2
(900 ft2)/(250 ft2/gal) = 3.6 gallons
Since we can't purchase .6 gallons we
must purchase 4 gallons of paint
The volume of the pool is 15X30X5 = 2250 ft3
1 ft3 = 7.48 gallons
2250(7.48) = 16,830 gallons of water

The equation that represents the road is y= ______
Answer:
[tex] y = \frac{1}{6}x - 5 [/tex]
Step-by-step explanation:
The equation that represents the road can be written as [tex] y = mx + b [/tex]
Find, m = slope, and b = y-intercept of the line.
Using two points on the line, (-6, -6) and (6, -4), find the slope:
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-6)}{6 -(-6)} = \frac{2}{12} = \frac{1}{6} [/tex]
Substitute x = -6, y = -6, and m = ⅙ into [tex] y = mx + b [/tex] to find b.
[tex] -6 = \frac{1}{6}(-6) + b [/tex]
[tex] -6 = -1 + b [/tex]
Add 1 to both sides
[tex] -6 + 1 = b [/tex]
[tex] -5 = b [/tex]
Substitute m = ⅙, and b = -5 into [tex] y = mx + b [/tex].
✅The equation that represents the road would be:
[tex] y = \frac{1}{6}x + (-5) [/tex]
[tex] y = \frac{1}{6}x - 5 [/tex]

A friend of yours wants to teach a dance class after school. She needs to rent a dance studio to teach the class, and the cost of rent is $400 for 12 weeks. The class will meet each week and your friend will charge each student the same fee for the whole course. Your friend's profit depends on how many students enroll in the course and how much she charges each student.
If your friend charges each student D dollars for the course, define a function, p, that relates the number of students who take the dance course, n, to the profit, p(n).
Answer:
p(n) = Dn - 400Step-by-step explanation:
As per given we have:
Spending = Cost of rent = $400Earning = D*nProfit = earning - spendingProfit is going to be:
p(n) = Dn - 400Fred opened a bank account with $310. He then deposits $55 per week. Stan started his bank account with $650 and withdraws $30 per week. Set up an equation to represent this situation. After how many weeks, w, will their bank accounts have the same amount in them

Bath and 1 yard of ribbon. She is 1/2 yard for project. She wants to divide the rest of the ribbon into pieces 1/4 yards long. How many 1/4 pieces of ribbon can she make
Answer:
2
Step-by-step explanation:
Given:
Total length of ribbon = 1 yard
Length of ribbon used for project = [tex]\frac{1}{2}[/tex] yard
Length of ribbon the rest of ribbon is to be divided = [tex]\frac{1}{4}[/tex] yard
To find:
The number of ribbons of length [tex]\frac{1}{4}[/tex] yard that can be made = ?
Solution:
Length of ribbon left after the 1 yard ribbon is used for project can be calculated by subtracting the length of ribbon used from the initial length of ribbon.
i.e.
Length of ribbon left = [tex]1-\frac{1}{2} =\frac{1}{2}[/tex] yard
Now, number of ribbon of length [tex]\frac{1}{4}[/tex] yard can be found be dividing the length of ribbon left with the length of ribbon pieces to be cut.
i.e.
Number of ribbons:
[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{1}{2}\times 4 = 2[/tex]
