Step-by-step explanation:
The sum of the angle measures a polygon with n sides is 720. What is n?
The polygon has 6 sides.
What is a polygon?
'A polygon, in geometry is any closed curve consisting of a set of line segments (sides) connected such that no two segments cross.'
According to the given problem,
Sum of measures of angle = 720
We know,
Sum of interior angles of polygon = 180( n - 2 )
Where, n = number of sides.
⇒ 180( n - 2 ) = 720
⇒ n - 2 = 720/180
⇒ n - 2 = 4
⇒ n = 6
Hence, we can conclude that the polygon has 6 sides.

In the diagram below, ST is parallel to QR. angle P is 40 degrees, and QST is 2R+8. Find the measure of STR in degrees.
Answer:
148º
Step-by-step explanation:
Use the information given:
The measure of a straight line is 180º. So angle PST=180-(2R+8)Since ST and QR are parallel, angle PST=angle PQR. Now, angle PQR=180-(2R+8)The sum of a triangle's interior angles is 180º. So 40+180-2R-8+R=180º.Combine like terms, 212-R=180Subtract, -R=-32Convert to positive, R=32ºWith R=32º, we can find angle QST and PQR. Angle QST=2(32)+8=64+8=72º. So angle PQR=180º-72º=108º. The sum of a quadrilateral's interior angles is 360º:
32º+72º+108º+STR=360ºCombine like terms, 212º+STR=360ºSubtract, STR=148ºAn electric plant consumed 420 tons of coal in 6 weeks. At this
rate, what will be the total consumption of coal after another 4
weeks?
Answer: 700 tons of coal consumed in 10 weeks.
Step-by-step explanation:
first you find how much coal is consumed in 1 week which is 70 tons, then you multiply the 70 tons by 10 weeks because you are trying to find how much tons of coal can be consumed in to weeks and when you do that you should get 700 tons of coal for 10 weeks.

Answer:
Amphibians! In order for water-dwelling animals to adapt to life on land, many new adaptations had to take place. First, they needed to be able to breathe air instead of obtaining oxygen from water. And fins don't work well as legs! They needed to be able to move around well on land.
What group of animals begins its life in the water, but then spends most of its life on land? Amphibians! Amphibians are a group of vertebrates that has adapted to live in both water and on land. Amphibian larvae are born and live in water, and they breathe using gills. The adults live on land for part of the time and breathe both through their skin and with their lungs as their lungs are not sufficient to provide the necessary amount of oxygen.
There are approximately 6,000 species of amphibians. They have many different body types, physiologies, and habitats, ranging from tropical to subarctic regions. Frogs, toads, salamanders , newts, and caecilians are all types of amphibians.

Isaac and jennifer's total cost for their business is given by C(x)= 40x + 96,000 and its revenue function is represented by R(x)= 60x. A. Set up the cost revenue and function
Answer: P(x) = 20x - 96,000
Step-by-step explanation:
Cost revenue and profit function.
Cost function;
C(x)= 40x + 96,000
Revenue function;
R(x)= 60x
Profit = Revenue - Cost
P(x) = 60x - (40x + 96,000)
P(x) = 20x - 96,000

A man got a 10% increase in his salary. If his new salary is Rs 1,54,000, find his original salary.
we will say that his original salary is x
x+10x/100=154000
we bring to the same denominator
(100x+10x)/100=154000
we multiply with 100
110x=15400000
we divide by 110
x=140.000

Answer:
A) Juan wins the race
B) J(t) = A (t) at (7 minutes, 2 miles)
C) The interval is 7 minutes to 15 minutes
Step-by-step explanation:
a) Juan wins the race
The reason is that the time Juan took to cover the distance of 4 miles is shorter than the time Antonio took
b) J(t) = A(t) at what point
This simply refers to the point at which the two graphs cross over one another
We can see this at the point ; (7,2)
This is; 7 seconds and 2 miles
What this mean is that they both covered 2 miles in 7 seconds
c) interval where J(t) > A(t)
This is the interval at which Juan was ahead of Antonio
Juan was below within 7 minutes
after 7 minutes he picked up
so the interval is 7 minutes - 15 minutes
