what is the sum of the measures of the interior angles of a hexagon
Answer:
Hexagon has 6, so we take 540+180=720. A heptagon has 7 sides, so we take the hexagon's sum of interior angles and add 180 to it getting us, 720+180=900 degrees.

6+ 3x = 15 with work!
Answer:
X=3
Step-by-step explanation:
Rearrange terms
6+3=15
3+6=15
Subtract from both sides of the equation
3+6=15
3+6−6=15−6
Simplify
Subtract the numbers
Subtract the numbers
3=9
x=3
X = 3.
Step-by-step explanation:
1) Subtract 6 from both sides.
[tex]3x = 15 - 6[/tex]
2) Simplify 15 - 6 to 9.
[tex]3x = 9[/tex]
3) Divide both sides by 3.
[tex]x = \frac{9}{3} [/tex]
4) Simplify 9/3 to 3.
[tex]x = 3[/tex]

The equation of the piecewise function f(x) is below. What is the value of f(3)?
Answer:
5
Step-by-step explanation:
Ask your self which equation you should use. Since it says F(3) then we have to find an equation that would fit this correctly. For example if we look at -X^2, X<-2 we could see that 3 is clearly not less than -2, leading to the conclusion that this is not the right equation.. If you look at the last equation it says that x has to be greater/equal to 0 which is true. So then we are left with the equation...
F(3)=x+2
F(3)=3+2
F(3)=5

A bike trail is drawn on a coordinate system. Each end of the trail is an x-intercept. The height of the trail is modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers. How many meters is the horizontal distance of the trail?
Answer:
4metres
Step-by-step explanation:
Given the height of the trail modeled by the function h(x) = -0.1x^2 - 0.3x +2.8 , where x is the horizontal distance in kilometers
The horizontal distance occurs at the x intercept i.e at h(x) = 0
Substitute
0 = -0.1x^2 - 0.3x +2.8 ,
Multiply through by -10
0 = x^2 + 3x - 28
x^2 + 3x - 28 = 0
Factorize
x^2 + 7x - 4x - 28 = 0
x(x+7) - 4 (x+7) = 0
(x-4)(x+7) = 0
x-4 = 0 and x+7 = 0
x = 4 and -7
Since the danced cannot be negative, hence the horizontal distance of the trail is 4m

find the 9th term for 150,60,24
Answer:
a(9) = 150*(0.4)^8 = 0.098304
Step-by-step explanation:
This is a geometric sequence, because each new term is 0.4 times the previous term.
The general formula for a geometric sequence is a(n) = a(1)*r^(n - 1). Here, with a(1) = 150 and r = 0.4, we have:
a(n) = 150*(0.4)^(n - 1), and so
a(9) = 150*(0.4)^8 = 0.098304

There are 10 chocolates in a box.
7 of the chocolates have soft centres and 3 of the chocolates have hard centres. Kyla takes at random a chocolate from the box and eats it.
She then takes at random another chocolate from the box and eats it.
The probability of getting chocolates with harder center is 7/15.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Given that, there are 10 chocolates in a box. 7 of the chocolates have soft centers and 3 of the chocolates have hard centers.
Probability of choosing first chocolate with hard center is
Total number of outcomes =10
Number of favorable outcomes =7
Now, probability is 7/10
Probability of choosing second chocolate with hard center is
Total number of outcomes =9
Number of favorable outcomes =6
Now, probability is 6/9
Probability of an event = 7/10 × 6/9
= 7/10 × 2/3
= 7/5 × 1/3
= 7/15
Therefore, the probability of getting chocolates with harder center is 7/15.

Read the following situation:
There are 13 animals in the barn. Some are chickens and some are pigs. There are 40 legs in all. How many of each animal are there?
When setting up the system, what could the variables represent? Select all that apply.
Total number of chicken legs
Total number of pigs
How long until the number of pigs and chickens are equal.
How many animals in the barn
Total number of pig legs
Total number of chickens
Where the lines cross
Answer:
Hi, let's turn the word problem into a set of equations:
Let's say that x = # of chickens, and y = # of pigs
If there are 13 animals altogether, that means that
x + y = 13
If there are 40 legs together, we know that chickens have 2 legs, while pigs have 4, so the total number of legs would be:
2x + 4y = 40
We now have two different equations, with the same two variables, so we can rearrange and substitute one equation into the other to solve. We can rearrange the first equation as:
x + y = 13
x = 13 - y
Let's plug this expression for "x" into the second equation:
2(13-y) + 4y = 40
Now we have an equation with only one variable, so we can use algebra to solve for y:
26 - 2y + 4y = 40
2y = 14
y = 7, there must be 7 pigs.
From the first equation that we rearranged,
x = 13 - y
Now that we know the numerical value of "y", we can plug that in:
x = 13 - 7
x = 6, there must be 6 chickens
Slope intercept form of 4x+4y=-32
Answer:
y = - x - 8
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c
Given
4x + 4y = - 32 ( subtract 4x from both sides )
4y = - 4x - 32 ( divide all terms by 4 )
y = - x - 8 ← in slope- intercept form
Answer:
x+y=-8
Step-by-step explanation:
-32=4x+4y
-4y=4x+32
y=(4x+32)/-4
y=-x-8
x+y=-8
Now comparing to slope intercept form
y=mx+c,we get
slope =1
y intercept =1
y=-8
What is the principal which would amount to $6900 in 3 years at 5% simple interest per annum?
Answer:
$6000
Step-by-step explanation:
accumulated amount = A = PI
A = $6900
Let P = x
6900 - I = x
I = (x)(0.05)(3yrs) = 0.15x
6900 - 0.15x = x
Add
6900 = 1.15x
Divide, solve for x
x = 6000

Answer:
D. One square and four triangles
Step-by-step explanation:
Cece is finding the surface area of a square pyramid by finding the sum of the areas of its faces
Square pyramid has a square base.
each edge of the square base joins at the top of the vertex to make a pyramid
The sides of the pyramid is a triangle
the square has 4 sides, so four triangle on the sides of the pyramid
