Answer:
102 mm²
Step-by-step explanation:
You can split the shape into two different shapes: a trapezium and a rectangle.
Area of rectangle = length x width
= 10 x 3 = 30mm
Area of trapezium = a + b / 2 x h
h = 9 - 3 = 6mm
= 10 + 14 / 2 x 6
= 72 mm
Total area = 72 + 30 = 102 mm²

Find the area of a regular octagon with an apothem length of 10 and a side length of 6.
Answer:
A = 240 units²
Step-by-step explanation:
the area (A) of a regular polygon is
A = [tex]\frac{1}{2}[/tex] pa ( p is the perimeter and a the apothem )
here p = 8 × 6 = 48 ( an octagon has 8 sides ) and a = 10 , then
A = [tex]\frac{1}{2}[/tex] × 48 × 10 = 24 × 10 = 240 units²
Answer:
Step-by-step explanation:
Preliminary task
Draw a regular octagon.
Draw a perpendicular from the side's midpoint to the center. (That is the apothem).
Draw two radii from the center of the side to the center of of the octagon. The endpoints of these two radii is the endpoints of the octagon's side.
The octagon has 8 such triangles.
Area one triangle
Area = 1/2 * side * apothem
side = 6
apothem = 10
Area = 1/2 6 * 10
Area = 30
Area of 8 such triangles.
Area = 8 * area of 1 triangle
area 1 triangle = 30
Area of 8 such triangles = 30*8 = 240

what is the slope of (2,5) (-6,-3)
Answer:
m=1
Step-by-step explanation:
(2,5);(−6,−3)

Answer:
[tex]\boxed{\sf{1}}[/tex]
Step-by-step explanation:
To solve this problem, you have to use a slope formula.
Slope formula:
[tex]\Longrightarrow: \sf{\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{Rise}{run} }[/tex]
[tex]\sf{y_2=(-3)}\\\\\sf{y_1=5}\\\\\sf{x_2=(-6)}\\\\\sf{x_1=2}[/tex]
Rewrite the problem down.
[tex]\sf{\dfrac{(-3)-5}{(-6)-2} }[/tex]
Solve.
[tex]\sf{\dfrac{(-3)-5}{(-6)-2}=\dfrac{-8}{-8}=\boxed{\sf{1} }[/tex]
Therefore, the slope is 1, which is our answer.I hope this helps you! Let me know if my answer is wrong or not.
i need help 9th grade math
Answer:
-x + 1
Step-by-step explanation:
f(x) = 2x + 3
g(x) = 3x + 2
we want to find (f-g)(x)
(f-g)(x) is the same as saying f(x) - g(x)
f(x) - g(x) = (2x + 3) - (3x + 2)
==> remove parenthesis and apply negative sign
f(x) - g(x) = 2x + 3 - 3x - 2
==> combine like terms
f(x) - g(x) = -x + 1

Answer:
This is pythagoras
A squared plus b squared equals c squared.
The unknown side is c as its the hypotenuse,
So the length of the first side is 6.4 this squared = 40.96
The other length is 12 as 6 is the radius so the diameter of the circle amd therfore the length of the triangle is 12.
12 squared is 144
144 + 40.96 = 184.96
The length of c squared is 184.96
To find the length of c alone we calculate the square root.
The square root of 184.96 = 13.6
? = 13.6

Answer:
X=121, y=59, w=59, z=53
Step-by-step explanation:
To find w, we know that the interior angles of a triangle are 180°. Thus ↓
180-31-90=59
For y, we know that y and w are opposite angles. Therefore, y = w = 59.
To find x, we know that there is a one straight line, so therefore we use ↓
180-59=121
Lastly, to find z, we know that the interior angles of a triangle are 180°. Thus ↓
180-59-68=53

to get a free meal tom at his fav resturant, tom needs to spend $50 or more at the resturant. he has already spent 30.25$ how much more does tom need to spend to get his free meal
how much more Tom needs to spend to get the free meal.
solution:subtract the amount he has spent from the amount he needs to spend to find how much more he needs to spend.
$50 - $30.25
= $19.75
Tom needs to spend $19.75 to get his free meal.

Step-by-step explanation:
So this area is 360 degrees
What you can see the 68 degrees is congruent to its opposing side so we can eliminate those. 360 - 126= 234
We can see m is congruent to U
234/2=117
m=117
. Mark drove 180 miles in 3 hours at
a constant speed. Let D equal the
distance traveled and t equal the time
traveled. Which of the following is
the constant of proportionality?
A) 3, as in D=3t
B) 60, as in D=60t
C) 180, as in D=180t
D) 540, as in D=540t
Answer:
d = 60t
Step-by-step explanation:
distance = d
time = t
every hour 60 miles are travelled so its 60t
referring to 60*time eg 60*3 = 180

9. A cooler contains 4.5 gallons of water and is filling up
at a rate of 0.1 gallons per second. A second cooler
contains 7 gallons of water and is draining at a rate of
0.25 gallons per second. Which could be used to
determine the number of seconds it would take for each
cooler to contain the same amount of water?
The equation that can be used to determine when each cooler would contain the same amount of water is 2.5 = 0.75t.
When the coolers would have the same amount of water?Equation that can be used to determine the amount of water in the first cooler at time t : 4.5 + 0.1t
Equation that can be used to determine the amount of water in the second cooler at time t : 7 + 0.25t
Where t represents seconds
When they have the same amount of water, the two above equations would be equal
4.5 + 0.1t = 7 + 0.25t
Combine similar terms
7 - 4.5 = 0.1t - 0.25t
2.5 = 0.75t
