Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of square A is 900 sq cm.
Answers
Answer:
The side of square A is 30 cm.
Step-by-step explanation:
Given that,
The dimensions of square A are three times the dimensions of square B.
The area of square A is 900 sq cm.
Side of square A = 3( side of square B)
Let the side of square B is b. So,
Side of square A, a = 3b
We know that, the area of square is side². So,
[tex](3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm[/tex]
Side of square A, a = 3(10) = 30 cm
Hence, the side of square A is 30 cm.
The Hogwarts Express train has reduced its one-way fare from 360 galleons to just 270 galleons. What is the percentage decrease in the fare? *
Answers
=======================================================
Work Shown:
A = old value = 360
B = new value = 270
C = percent change
C = (B-A)/A
C = (270-360)/360
C = -90/360
C = -0.25
C = -25%
The negative C value indicates we have a percent decrease.
Note how 25% of 360 = 0.25*360 = 90, meaning that the price has dropped by 90 galleons. And also note that 360-270 = 90 is that same figure of 90. This helps confirm the answer.

Triangle PQR has vertices P(-2, 6), Q(-8, 4) and R(1, -2). It is translated according to the rule (x, y)—> (x, - 2, y -16).
What is the y-value of P’?
a. -18
b. -16
c. -12
d. -10
Answers
===============================================
To find this answer, you apply the given translation rule to the coordinates of point P(-2,6)
[tex](x,y) \to (x-2, y-16)\\\\(-2,6) \to (-2-2, 6-16)\\\\(-2,6) \to (-4, -10)\\\\[/tex]
We see that point P' has a y coordinate of -10
This translation, aka shifting, rule moved point P 2 units to the left and 16 units down.

A ) Phishing
B ) Pharming
c ) Smishing
Answers
Answer:
B ) Pharming
Step-by-step explanation:
When the user types in a URL they are directed to a fake website this is known as Pharming. This is one of many cyber attacks and usually occurs from a virus that has found it's way into your personal computer or server. The harmful virus basically waits until you open your internet browser and type in a URL to a specific website. Instead of taking you to that correct website it will take you to a replica site which will send all the information that you input, back to the creator of the virus. This is done so that they can obtain all of your personal information including bank details.
A regular polygon with exterior angle of 45° is redrawn using a scale 1 : 5. If the actual length of the sides of the regular polygon is 10cm, calculate the perimeter of the scale drawing of the regular polygon.
Answers
Answer:
16 cm
Step-by-step explanation:
"regular polygon" means all sides and angles are the same.
the sum of all exterior angles must be 360 degrees.
so, how often do 45 fit into 360 ?
2 times in 90, which in turn fit 4 times into 360, so 8 times.
the polygon has 8 corners and 8 sides.
each side is originally 10cm
so the original perimeter is 8×10 = 80 cm
now, every side is reduced to 1/5th of the original size, this also reduces the perimeter by the same factor.
=> perimeter = 80×(1/5) = 80/5 = 16 x cm
control :
applying the scaling factor of 1/5th to every side transforms every side from 10 cm to 2 cm.
we still have 8 sides.
perimeter = 8 × 2 = 16 cm

How many four digit numbers cannot be divided by 5?
Answers
Answer:
7200
Step-by-step explanation:
Since the first digit cannot be zero,
there are 9*10*10*10 = 9000 4-digit numbers.
Each of these with a last digit not equal 5 or 0 is not divisible by 5.
Therefore, there are 8 choices of last digit
9*10*10*8 = 7200
SUPER URGENT: Complete the general form of the equation of a sinusoidal function having an amplitude of 6, a period of 2pi/3, and a phase shift to the left 1 unit.
y =
Answers
Answer:
y = 6·sin(3·(x - 1)) + c
Step-by-step explanation:
The general form of an equation for a sinusoidal function is presented ad follows;
y = a·sin(b·(x - h) + c
Where;
a = The amplitude of the equation
T = The period = 2·π/b
h = The phase shift
c = The vertical shift
From the question, we have;
a = 6,
2·π/3 = 2·π/b
∴ b = 3
h = 1
We get;
y = 6·sin(3·(x - 1)) + c.

Answer:
1/3 = 56/168
5/8 = 105/168
4/7 = 96/168
Step-by-step explanation:
the simplest approach to common denominator is by just multiplying all different denominators:
3 × 8 × 7 = 168
3 and 7 are prime numbers (no other whole number factors are a part of them).
8 has sub-factors : 4 and 2
but we cannot build any multiplication products with them and 3 and 7 that is then divisible by 8.
so, actually, 168 is the smallest common denominator.
so, to bring every fraction to a 168 denominator, we need to calculate the scaling factor between the original fraction denominator and the new one.
for 1/3 we have therefore to calculate 168/3 = 56
for 5/8 we have to calculate 168/8 = 21
for 4/7 we have to calculate 168/7 = 24
and so
1/3 = 1×56/168 = 56/168
5/8 = 5×21/168 = 105/168
4/7 = 4×24/168 = 96/168
