Answer:
If we have two figures, F and F'
Such that if we start with F, and dilate it with a scale factor K, we get F'.
We will have:
All the measures of F', are K times the correspondent measures of F.
Then if F has s₁, s₂, ..., sₙ sides, the sides of F' will be:
K*s₁, K*s₂, ..., K*sₙ
The ratio between correspondent sides will be equal to K
The ratio between perimeters will also be equal to K (because the perimeter is the sum of all the sides of each figure, so we can just take K as a common factor)
In the case of the area, because we usually multiply a measure by another, a factor K^2 will appear, and the quotient between the areas is K^2
And finally, for the volumes, the ratio will be K^3
a) The ratio of corresponding lengths is K, in this case is 5/2
b) The ratio of the perimeters is K, in this case is 5/2
c) The ratio of the areas is K^2, in this case is (5/2)^2 = 25/4
d) The ratio of the areas is K^3, in this case is (5/2)^3 = 125/8
e) Two figures are similar if the figures have the same shape, then the corresponding angles are exactly the same, then the ratio of corresponding angle measures is 1.

Justin reads 21 pages of a book each day.
How many pages will he read in 6 days?
125
27
126
15
Answer:
126
Step-by-step explanation:
Take the number of pages read per day and multiply by the number of days
21 pages per day * 6 days =126 pages
Answer:
126
Step-by-step explanation:
it can not be A,B & D because when you multiple 21 pages by 6 days you get 126.

What is the perimeter,in centimeters of triangle QRS?
Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
[tex]\sqrt{225}[/tex] = 15 (this is the missing length for QS
To find the perimeter, add all the sides...
15 + 20 +25 = 60
Miguel walked Ask Your Teacher mile to the library and then Ask Your Teacher mile to the post office. How can he write Ask Your Teacher and Ask Your Teacher as a pair of fractions with a common denominator?
Answer:
[tex](\frac{5}{10},\frac{6}{10})[/tex]
Step-by-step explanation:
Given
[tex]Library \to \frac{1}{2}[/tex]
[tex]Post\ Office \to \frac{3}{5}[/tex]
See comment for complete question
Required
Write as a common denominator
Take the denominator of both fractions
[tex]2 \to[/tex]
[tex]5 \to[/tex]
Calculate the LCM
[tex]2 \to 1 * 2[/tex]
[tex]5 \to 1 * 5[/tex]
[tex]LCM = 1 * 2 * 5[/tex]
[tex]LCM = 10[/tex]
Multiply the numerator and the denominator of both fractions by 10
Simplify each to ensure a denominator of 10
[tex]\frac{1}{2} \to \frac{1}{2} * \frac{10}{10} \to \frac{1}{1} * \frac{5}{10} \to \frac{5}{10}[/tex]
[tex]\frac{3}{5} \to \frac{3}{5} * \frac{10}{10} \to \frac{3}{1} * \frac{2}{10} \to \frac{6}{10}[/tex]
Hence, the pair is:
[tex](\frac{5}{10},\frac{6}{10})[/tex]

what's the absolute value of 4.5 ?
Answer:
the absolute value or 4.5 is 4.5
Step-by-step explanation:
Answer:
4.5
Step-by-step explanation:
absolute value: the distance away from zero, it will always be positive because distance can't be negative.
thus, the absolute value of 4.5 = the distance of 4.5 to zero, which is 4.5
|4.5| = 4.5
inequality:
-3 -6 (4x+6) > - 111
solve
Answer:
x < 3
Step-by-step explanation:
-3 - 6(4x+6) > - 111
-3 - 24x - 36 > -111
-24x - 39 > -111
-24x > -72
dividing by a negative flips the sign
x < 3
Bob is 6 feet 2 inches tall.
There are
2.54 centimeters in 1 inch.
What is Bob's height in meters?
Z
A) 1.8796 meters
B) 18.796 meters
C) 74 meters
D) 15.748 meters
E) 1.5748 meters
F) None of the above
Answer:
A, 1.8796
Step-by-step explanation:
First, convert everything to inches
6 × 12 = 72
72 + 2 = 74
Now, we convert the inches to centimeters
2.54 × 74 = 187.96
Next, we convert to meters
187.96 ÷ 100 = 1.8796
So, your answer would be A, 1.8796 meters

The volume of a cube is 64 cubic meters. What is the surface area of the cube, in square meters?
Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.

A quadratic function is shown. f(x) = -x^2+7x-12 one factor of this function is (x-4). What is the other factor of the quadratic function?
Answer:
The other term is (x-3)
Step-by-step explanation:
The quadratic function is:
[tex]f(x)=-x^{2}+7x-12[/tex]
Factoring this function we will have:
[tex]f(x)=-(x-4)(x-3)[/tex]
Therefore, the other term is (x-3).

Which is the factored form of x(w – 1) + (W – 1)?
22 pts
Answer:
Solution given:
x(w – 1) + (W – 1)
distribute it:
xw-x+w-1
xw+w-x-1
take common from each term
w(x+1)-1(x+1)
take common again
(x+1)(w-1)
the factored form of x(w – 1) + (W – 1) is (x+1)(w-1).
