Work out the perimeter of a regular octagon with side length 2.6mm
Answer:
20.8mm
Step-by-step explanation:
We know that an octagon has 8 sides, and since this is a regular octagon we can safely say that all sides are equal.
This means all sides are 2.6mm.
So if we run the calculation:
2.6mm × 8 = 20.8mm (Side Length × Number of Sides = Perimeter)
We have our final answer!
(d) Find the value of k so that kx + 5y = 10 makes an angle of 30° with y-axis.
Answer: k = -8.66
Step-by-step explanation:
We have the equation:
k*x + 5*y = 10
First, let's rewrite this as a line in the slope-intercept form:
5*y = 10 - k*x
y = 10/5 - (k/5)*x
y = -(k/5)*x + 2
Now, we want to make an angle of 30° with respect to the y-axis.
Then we can think on a triangle rectangle, where we know one angle of 30°, the adjacent cathetus will be equal to the difference between the y-component and the y-intercept, and the opposite cathetus will be equal to the x-component.
To get this, we first need to evaluate the function in one given point, let's use x = 5. (we could use any value of x here, i use 5 because it is easier)
y = -(k/5)*5 + 2
y = -k + 2
then the cathetus of our triangle will be:
adjacent cathetus: (y - 2) = (-k + 2 - 2) = -k
opposite cathetus: x = 5.
Now we know the relation:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
where a = 30°
Then:
Tan(30°) = 5/(-k)
-k = 5/tan(0.577) = 8.66
k = -8.66
This is the value of k that we wanted to find.
Which method correctly solves the equation using the distributive property? Negative 0.2 (x minus 4) = negative 1.7
Answer:
4.85
Step-by-step explanation:
Given :
Negative 0.2 (x minus 4) = negative 1.7
-2(x - 4) = - 1.7
-2x + 8 = - 1.7
-2x = - 1.7 - 8
-2x = - 9.7
Divide both sides by - 2
-2x / 2 = - 9.7 / - 2
x = 4.85
porfavor: 5(x+9) = 2(x+30)= cuanto es?
Step-by-step explanation:
Primero encontramos el valor de x,
5(x+9) = 2(x+30)
=> 5x + 45 = 2x + 60
=> 5x - 2x = 60 - 45
=> 3x = 15
[tex] = > x = \frac{15}{3} [/tex]
=> x = 5
Como tenemos el valor de x entonces,
LHS = 5(x+9) RHS = 2(x+30)
= 5(5+9) = 2(5+30)
= 5 × 14 = 70. = 2 × 35 = 70
Por tanto, el valor es,
5 (x + 9) = 2 (x + 30) = 70 (Ans)

Find the composition of transformations that map ABCD to EHGF. Reflect over the x axis then translate.
Answer:
[(x + 6), (y + 1)]
Step-by-step explanation:
Vertices of the quadrilateral ABCD are,
A → (-5, 2)
B → (-3, 4)
C → (-2, 4)
D → (-1, 2)
By reflecting the given quadrilateral ABCD across x-axis to form the image quadrilateral A'B'C'D',
Rule for the reflection of a point across x-axis is,
(x, y) → (x , -y)
Coordinates of the image point A' will be,
A(-5, 2) → A'(-5, -2)
From the picture attached, point E is obtained by translation of point A'.
Rule for the translation of a point by h units right and k units up,
A'(x+h, y+k) → E(x', y')
By this rule,
A'(-5 + h, -2 + k) → E(1, -1)
By comparing coordinates of A' and E,
-5 + h = 1
h = 6
-2 + k = -1
k = 1
That means
Rule for the translation will be,
[(x + 6), (y + 1)]
A storekeeper increased the price of hats by `5\%`. A hat was originally priced at `\$15.00`. What is the new cost of the hat?
Answer: $15.75
Step-by-step explanation:
From the question, we are informed that a storekeeper increased the price of hats by 5% and that the hat was originally priced at $15.00.
The new cost of the hat will be:
= $15.00 + (5% × $15.00)
= $15.00 + (5/100 × $15.00)
= $15.00 + (0.05 × $15.00)
= $15.00 + $0.75
= $15.75
The new cost of the hat is $15.75

Mr. Smith wants to order some pizza and cheese pizza cost $11 and pepperoni pizza cost $12.50 if you bought 13 pieces total and paid $153.50 how many pepperoni pizza did he buy
Answer: Mr Smith bought 7 pepperoni pizza
Step-by-step explanation:
Step 1
cost of cheese pizza =$11
pepperoni pizza cost =$12.50
let number cheese pizza be represented as c
and number of pepperoni pizza be represented as p
such that the total number of pizza bought which equals 13 can be represented as
c+ p= 13
and total cost of both pizza can be expressed as
11c+ 12.50p =153.50
Step 2 Solving
c+ p= 13
11c+ 12.50p =153.50
By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2
11c+ 12.50p =153.50
11c+ 11p=143.
1.5p =10.5
p= 10.5/ 1.5 =7
c+ p= 13
c= 13-p =13-7=6
Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza

please help(: (8th grade lesson)
Step-by-step explanation:
Since the sum of the angles in a straight line is 180, and we know that angle four is 120, to find angle 3, simply subtract 120 from 180.
Angle 3 is 180-120 = 60
Since we know 2 angles already, we have: 60 + 95 = 155. Now subtract that from 180.
Angle 1 is 180-155 = 25

Answer:
Option D
Step-by-step explanation:
From the spinner we see there are 5 colours in there.
These are;
Green, Yellow, Red, Purple, Blue.
This means that when it is spinned, there's possibility of getting only one colour per spin.
Since she tosses a coin as well for each spin, there's a possibility of getting either a tail or head per spin.
This means, all possible outcomes will be 5 × 2 = 10 outcomes.
With each colour possibly showing up with either tail or head.
Correct answer is Option D as it has 10 possible outcomes in the correct order.
At the store a cell phone cost 1.1 times as much as it sells online. If it cost $888.98 online, how much more does it cost from the store.
Given:
At the store a cell phone cost 1.1 times as much as it sells online.
The cost of it is $888.98 online.
To find:
How much more does it cost from the store?
Solution:
It is given that,
Cost of a cell phone online = $888.98
At the store a cell phone cost 1.1 times as much as it sells online. So, cost of the cell phone at store is
[tex]1.1\times (888.98)=977.878 [/tex]
The cost of cell phone at store is $977.878 .
The difference between the cost of cell phone at store and online is
[tex]\$977.878 -\$888.98=\$88.898[/tex]
Therefore, the cell phone cost is $88.898 much more at the store.

The faster you drive the less time it takes to reach your destination (a driver's speed is inversely proportional to the drive time). Mike takes 45 minutes to
travel from point a to point b at 60 miles and hour. Kelly takes the same trip at 80 miles an hour. How long does the trip take Kelly? (Round to the nearest
whole number)
Answer:
The time the trip takes Kelly is approximately 34 minutes
Step-by-step explanation:
The topic examined by the question is the relationship between speed, distance traveled, and time which is presented here as follows;
[tex]Speed, \ S = \dfrac{Distance \ travelled \ 'd'}{Time \ taken \ 't'}[/tex]
The given parameters of the journey are;
The time it takes Mike to travel from point 'a' to point 'b' = 45 minutes
The speed with which Mike travels = 60 miles an hour
The speed with which Kelly travels the same trip = 80 miles an hour
Let 'd' represent the distance from point 'a' to point 'b', and let 't' represent the time the trip takes Kelly
For Mike, we have;
S = d/t
∴ d = S × t
Where;
S = 60 miles per hour
t = 45 minutes = 0.75 hour
d = 60 miles/hour × 0.75 hour = 45 miles
The distance from point 'a' to point 'b' = d = 45 miles
Similarly, from S = d/t, we have for Kelly the time 't' given as follows;
t = d/S
Where;
S = 80 miles/hour
d = 45 miles
∴ t = 45 miles/(80 miles/hour) = 9/16 hour = 9/16 hour × 60 min/hour = 33.75 minutes
The time the trip takes Kelly = 33.75 minutes ≈ 34 minutes.
