A hexagon as all sides of length 2 cm. What will the area of the hexagon be, if it is enlarged with scale factor 3?
Answer: [tex]93.53\ cm^2[/tex]
Step-by-step explanation:
Given
The side of the hexagon is [tex]a=2\ cm[/tex]
If it enlarged with scale factor 3 i.e. each side is 3 times before
The new side of the hexagon is [tex]a'=3\times 2=6\ cm[/tex]
The area of the hexagon is
[tex]A=\dfrac{3\sqrt{3}}{2}a^2[/tex]
Putting values we get
[tex]\Rightarrow A=\dfrac{3\sqrt{3}}{2}\times 6^2\\\\\Rightarrow A=\dfrac{3\sqrt{3}}{2}\times 36=54\sqrt{3}\ cm^2\\\\\Rightarrow A=93.53\ cm^2[/tex]
Find two mixed numbers so that the sum is seven wholes and two eights and the difference is two wholes and four eigths
Answer:
Step-by-step explanation:
x + y = 7 + 2/8 = 58/8
x - y = 2 + 4/8 = 20/8
Add the equations together
2x = 78/8
x = 39/8
y = x - 20/8 = 19/8
x = 39/8 = 4⅞
y = 19/8 = 2⅜

Answer:
area = 120.7 cm²
Step-by-step explanation:
net area = area of rectangle - area of semi-circle
area = (19 x 7.5) - 1/2(3.14)(4.5²)
area = 152.5 - 31.8 = 120.7 cm²

Find the hcf of 27 and 36
Answer:
9
Step-by-step explanation:
A superhero and his sidekick simultaneously leave the city and fly toward a secret hideout that is 1800 km away. The superhero's speed is 100 km/h slower than the sidekick's speed, and so he arrives at the hideout 36 minutes after his sidekick. Find the speed of each
Answer:
Speed of sidekick : 600
Speed of superhero : 500
Step-by-step explanation:
x = sidekick speed
speed of hero = x-100
Time of hero = -36
1800/(x-100) = (1800/x) + 0.6
That equations solves to x = 600 and x = 500 or -500
The given difference in speed and the arrival time, as well as the
distance traveled, gives the speeds as 500 and 600 km/hr.
Response:
The speed of the superhero is 500 km/hr.The speed of the sidekick is 600 km/hr.Which method is used to calculate the speed of the superhero, and the sidekick?The given parameters are;
Superhero's speed = 1800 km
Speed of the superhero = Speed of the sidekick - 100 km/h
The time the superhero arrives at the hideout = 36 minutes after the sidekick = 0.6 hours
Required:
The speed of the superhero and the sidekick
Solution:
Let v represent the speed of the superhero, we have;
v × (t + 0.6) = (v + 100) × t
v·t + 0.6·v = v·t + 100·t = 1800
0.6·v = 100·t
[tex]t = \dfrac{0.6}{100} \cdot v[/tex]
Therefore;
0.006·v² + 0.6·v - 1800 = 0
Which gives;
v² + 100·v - 300,000 = 0
(v - 500)·(v + 600) = 0
v = 500, or v = -600
The speed of the superhero is 500 km/hThe speed of the sidekick is 500 km/h + 100 km/h = 600 km/hLearn more about speed and velocity here:

Matt saves 7 dollars every week in order to buy a guitar. Write an equation, using x for the independent variable and y for the dependent variable. If he saved for 19 weeks, how much money did he save?
Answer:
y = 7x
y = $133
Step-by-step explanation:
x = independent variable
y = dependent variable
y = 7x
Where,
y = total amount saved
x = number of weeks
7 = constant
When x = 19
y = 7x
y = 7 * 19
y = 133
y = $133

A square has a perimeter of 28
inches. Another square has a
perimeter of 20 inches. What
is the difference of their
areas?
Answer:
24
Step-by-step explanation:
To find the side length of a square, you have to divide the perimeter by 4 (since a square has 4 sides). 28 divided by 4 is 7 and 20 divided by 4 is 5. to find the area of each square, you have to multiply each side length by two. 7 times 7 is 49 and 5 times 5 is 25. 49 minus 25 is 24.

Find the 11th term in the geometric sequence: 4, 6, 9,....
Answer:
A11 = 230.66015625
Step-by-step explanation:
hi!
the first thing that you have to do when solving for the 11th term in a geometric sequence is to find the common ratio!
I did this by dividing 6/4 = 3/2 (I did multiply this by 6 to test if it was correct, and it was)
the next thing you can do is use this formula:
An = A1*r^(n-1)
An = the nth term of the sequence
A1 = the first term in the sequence
r = common ratio
n = the number of term that you are solving for
A11 = 4*(3/2)^(11-1)
A11 = 4*(3/2)^10
A11 = 230.66015625

Part B: Determine mob.

B
Answer:
m∠SBE = 26°, [tex]m\hat O B[/tex] = 126°
Step-by-step explanation:
The arc of a circle is a portion of the circumference of the circle. For a circle, the degree measure of an arc is equal to the measure of the central angle that intercepts the arc.
Central angle is an angle whose vertex is on the center of the circle and endpoints on the circumference of the circle. If the endpoints of the central angle are are also the endpoints for the angle's intercepted arc, then both angles are congruent.
Also, the angle at the center is twice the angle at the circumference.
Angle at center = [tex]m\hat S E[/tex] = 52° (central angle is congruent with angle that intercept the arc)
2 * m∠SBE = central angle (angle at the center is twice the angle at the circumference)
2 * m∠SBE = 52
m∠SBE = 26°
2 * m∠BEO = central angle (angle at the center is twice the angle at the circumference)
2 * 63 = central angle
central angle = 126°
Angle at center = [tex]m\hat O B[/tex] = 126° (central angle is congruent with angle that intercept the arc)

Angle = 90 degrees
Two side lengths = 5 cm
Given that one of the angles is 90 degrees, then it means that the triangle is a right triangle.
Also since two sides are equal, then the triangle is an isosceles triangle, and the other angles are 45 degrees each
Hence, the true statements about the triangle are (a), (c) and (e)

Hina is converting £270 into S. She knows that £1 = €1.11 and €1 = $1.21. How many S will
Hina get? Give your answer to 2 dp
HELP PLEASE
Answer:
$362.64
Step-by-step explanation:
Assuming that "S" represents the money in U.S. dollars, we are given the starting amount as 270 pounds.
We first need to convert the pounds into euros, since £1 = €1.11
So all we have to do is £270 × €1.11 = €299.70
Then, we need to convert euros into dollars, since €1 = $1.21
So all we have to do here is €299.70 × $1.21 = $362.637
Which rounds to $362.64
