12. What is the sum of the interior angles for a pentagon? (1 point)
900
540°
720°
108°
Answer:
540°
Step-by-step explanation:
Consider a regular pentagon. Divide it radially into five congruent, isosceles triangles. Each triangle has a vertex angle of 360°/5 = 72°, and base angles of (180°-72°)/2 = 54° each.
An interior angle of the pentagon is made up of two of those 54° angles, so interior angle = 108°.
Sum of interior angles = 5·108° = 540°

The value of a collectible toy is increasing exponentially. The two points on the graph
show the toy's initial value and its value 3 weeks afterward.
The question is incomplete. Here is the complete question.
Part A
The value of a collectible toy is increasing exponentially. The two points on the graph show the toy's initial value and its value 3 weeks afterward.
Express the toy's value t, in dollars, as a function of time w in weeks after purchase.
Part B
Write an expression to represent the toy's value 10 days after purchase
Answer and Step-by-step explanation: An exponential function is of the form: [tex]y=ab^{x}[/tex]
Part A
Translating to the question, the toy's value as a function of time is
[tex]t=ab^{w}[/tex]
To determine constants a and b, we use points given by graph.
First, (0,5) to find a:
[tex]5=a.b^{0}[/tex]
a = 5
Now, (3,10) to determine b:
[tex]10=5b^{3}[/tex]
[tex]b=\sqrt[3]{2}[/tex]
b = 1.26
The toy's value as a function of time in weeks is [tex]t=5.(1.26)^{w}[/tex]
Part B
Since, the function is in weeks:
1 week = 7 days
w weeks = 10 days
[tex]w = \frac{10}{7}[/tex]
Replacing w:
[tex]t=5.(1.26)^{w}[/tex]
[tex]t=5.(1.26)^{10/7}[/tex]
Expression that represents toy's value after 10 days is [tex]t=5.(1.26)^{10/7}[/tex].

Answer:
Step-by-step explanation:
Radius 4.5 feet what’s is the tabletop area
The area of the table top is 63.62 square feet.
What is area in geometry?
'In geometry, the area can be defined as the space occupied by a flat shape or the surface of an object.'
According to the given problem,
Radius of the table = 4.5 feet
Since, the table is round,
Area of a circle = [tex]\pi r^{2}[/tex]
= π × 4.5 × 4.5
= 63.617
Hence, we can conclude, the area of the table-top is 63.62 square feet.

An orchard has 8 times many apple trees as pear trees. There are 981 trees in all. How many more apple trees than pear trees does have it?
Answer:
there are 763 more apple trees than pear trees
Step-by-step explanation:
so, first we write the words into equations.
8P = A because there are 8x apples per x pear, so to make it equal we must multiply pears by 8. P+A = 981. replacing "A" in the second equation with "8P" to get P+8P=981=9P divide both sides by 9 to get 109 pear trees. knowing this we can get 981-109=A=872 apple trees. the problem asks for A-P which we can replace the numbers to get (872)-(109)=763 more trees
There are 763 more Apple trees than Pear trees.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
let the number of pear trees be x.
An orchard has 8 times many apple trees as pear trees.
So, Apple trees = 8x
Now, total trees = 981
x+ 8x= 981
9x= 981
x= 981/9
x = 109
and, Apple trees = 8 (108)= 872.
So, there are 763 more Apple trees than Pear trees.
