Polygon Y is a scaled copy of polygon X using a scale factor of 1/3. Polygon Ys area is what fraction of polygons Xs area?
Answer:
The answer is "[tex]\bold{\frac{1}{9}}[/tex]"
Step-by-step explanation:
In this question, when two figures are similar so, the ratio from its size is equal to the squared factor that are:
Scaling factor= Z
Area of Polygon Y=a
Area of Polygon X=b
[tex]z=\frac{1}{3}\\\\using \ substitution:\\\\(\frac{1}{3})^2=\frac{a}{b}\\\\\frac{1}{9}=\frac{a}{b}\\\\a=\frac{1}{9}b[/tex]
a boat travels 45 miles east then 60 miles north how far is it from where it started
Answer:
SOLUTION: A boat travels 45 miles east then 60 miles north, how far is it from where it started. Draw this. The hypotenuse of the right triangle is the square root (45^2)+(60^2)=square root of 2025=3600=square root of 5625, or 75 miles. If you divide 45 and 60 by 15, you get 3 and 4, and the hypotenuse is 5.

Answer:
Find the slope this way Hanna,
Step-by-step explanation:
slope = m
m = (y2-y1) / (x2-x1)
you are given the two points
P1 = (-2,-6) in the form (x1,y1)
P2 = (2,2) in the form (x2,y2)
plug those into the slope formula above
m = (2-(-6) ) / (2 - (-2) )
m = (2 +6) / (2+2)
m = 8 / 4
m = 2

A triangular road sign has a height of 3 feet and a base of 2.5 feet. How much larger in area is this sign than one with a height of 2.5 feet and a base of 3 feet?
Answer:
Not larger or smaller; the areas are the same
Step-by-step explanation:
Recall that the formula for the area of a triangle of base b and height h is
A = (1/2)(b)(h).
In the first case, h = 3 ft and b = 2.5 ft. This results in an area of 3.75 ft^2.
In the second case, h = 2.5 ft and b = 3 ft. The area is the same: 3.75 ft^2.
This is because A = (1/2)(b)(h) has the same value regardless of the order in which b and h are used as multipliers.
There is no difference in the areas of the two signs. The areas are the same.

HELPPPP I have no idea how to do graphhhsssss
Answer:
Follow the lines
Step-by-step explanation:
Follow what the lines go with what the table has.
To make this really easy, find the slope of the line
To do this you find an easy point.
Ex. x=3 and y= 150
then take it into a slope y-intersept formula
y= mx
150= 3x
50 = x
so for every time x goes up one interval, y increases at a rate of 50.
And for y, do the opposite, for every 50 y, x goes up 1.
By following this linear path, you should really beable to solve the graph on the right. (If you need to, use a calculator for dividing the y numbers by 50 to get x)
y= 50x is ur slope/formula
(Ill leave the rest for you to answer with this data above ;) )

a rectangular picture with a perimeter of 27 cm is glued in the center of a rectangular piece of cardboard. there is a 1 cm margin (of empty cardboard) all around the picture. what is the perimeter of the peice of cardboard
Answer:
31 cm
Step-by-step explanation:
A rectangle has 4 sides.
27 cm + 4 cm = 31 cm.
The perimeter is 31 cm.
If you are confused, to find perimeter you add all the sides up. That is why I added 1 + 1 + 1 + 1 / 4.
For inches or a different measure I recommend just converting it. You never mentioned the measure so I decided with cm.

Answer:
For a trapezium of height H, parallel side 1 X, and parallel side 2 Y, the area is:
A = (1/2)*H*(X + Y)
with this we can complete the table.
a)
Here we know:
X = 7cm
Y = 11cm
H = 6cm
Then: A = (1/2)*6cm*(7cm + 11cm) = 54 cm^2
b)
Here we know:
X = 8 m
Y = 10 m
A = 126 m^2
Then:
126 m^2 = 0.5*H*(8m + 10m)
126 m^2 = H*9m
126 m^2/9m = H = 14m
Then the height of this trapezoid is 14m
c)
Here we know:
X = 5mm
H = 8mm
A = 72 mm^2
Then:
72 mm^2 = 0.5*8mm*(5mm + Y)
72 mm^2 = 4mm*(5mm + Y)
72mm^2/4mm = 5mm + Y
18 mm = 5mm + Y
18mm - 5mm = Y
13 mm = Y
Then the parallel side 2 is 13 mm long.

What is the value of the function? f(x)=(−2)^3 (3)^0 (4)^−2
Answer:
-1/2
Step-by-step explanation:
hello :
f(x)=(−2)^3 (3)^0 (4)^−2
(−2)^3 = -8
(3)^0 =1
(4)^−2 1/ (4)^2 =1/16
so : f(x) = (-8)×(1)×(1/16) = -8/16 = -1/2

What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
From the figure,
tan Θ = 5.8 / 1.5
Θ = tan (5.8 / 1.5)
Θ = 75.5°
The angle is between 70° and 80°.
Thus,
The ladder is safe.

which table and graph represents the equation y=2x i give brainly wjo ever it correct
Answer:
graph a and table a=B
Step-by-step explanation:
This is because for table a, if you subsite the numbers of x it would give you the answer for y such as y=2x, and since x is 2 y is 4, which is shown on the graph. And since it does not have any add ons, if you make x 0 it would be 0 so it would also be proportional through the orgin. so graph A is also correct.

maths angles- please help asap
Answer:
x = 20
Step-by-step explanation:
These angles are same-side supplementary, therefore they add up to 180°.
[tex]4x + 5x = 180 \\ 9x = 180 \\ x = 20[/tex]
Answer:
4x + 5x = 180
because of interior angle
hence, 9x = 180
x = 180/9
x = 20
one angle = 20*4 = 80
another angle = 20*5 = 100

Step-by-step explanation:
In the question it states that the number in the hundreds place should be twice the number in the hundredth place.
142.72
1 is in the hundreds place. Now the value in the hundredth place should be twice the value of 1. When it say twice it says 2 times the number. 1 time 2 = 2 which would make the answer true.
