if Tim has read 10% of the book, that means he still hasn't read 90% of it yet, and we know that that 90% is 45 pages, so say the book has a total amount of pages of "x", which is 100%.
[tex]\begin{array}{ccll} pages&\%\\ \cline{1-2} 45&90\\ x&100 \end{array}\implies \cfrac{45}{x}=\cfrac{90}{100}\implies \cfrac{45}{x}=\cfrac{9}{10} \\\\\\ 450=9x\implies \cfrac{450}{9}=x\implies 50=x[/tex]

In a scientific study there are 7 guinea pigs, 4 of which are pregnant. If 3 are selected at random without replacement, find the probability that all are pregnant. Enter your answer as a fraction or a decimal rounded to 3 decimal places.
The chances of selecting a pregnant guinea pig involves probability
The probability that all are pregnant is 0.187
How to determine the probabilityProbabilities are used to determine the chances of events
From the question, 4 out of 7 guinea pigs are pregnant.
So, the probability that a selected guinea pig is pregnant is:
[tex]p = \frac 47[/tex]
The probability that all the selected 3 are pregnant is then calculated as:
[tex]p = \frac 47 * \frac 47 * \frac 47[/tex]
Evaluate the product
[tex]p = 0.187[/tex]
Hence, the probability that all are pregnant is 0.187

How can you be certain that the angles you have created form a square inside the circle?
Answer:
By Ensure that its angles are identical, and also ensure that circle's diameter is only smaller than the square because then the circle diameter multiplies the range by 2, so how you can find the formula of the radius over
The building process is as follows:
Circle diameter is plotted.
The method as described in the perfectly straight central axis of a portion is drawn by the bisector of the right angle of the radius.
It is also a circular pattern diameter.
The four areas on the circle that result are indeed the square vertices.

Jannette says because 's sides form a Pythagorean triple and 's side lengths are multiples of 's side lengths. Is she correct? Explain your reasoning.
The similar triangles ABC and DEF may or may not have equal lengths
Janette's claim that triangles ABC and DEF are similar triangle is true
How to prove or disprove Janette's claim?Start by calculating the length of the third sides using the Pythagoras theorem.
[tex]a^2 = b^c + c^2[/tex]
For triangle ABC, we have:
[tex]AC^2 = 20^2 + 21^2[/tex]
[tex]AC = 29[/tex]
For triangle DEF, we have:
[tex]58^2 = 40^2 + EF^2[/tex]
This gives
[tex]EF^2 = 58^2 - 40^2[/tex]
[tex]EF = 42[/tex]
So, we have the following corresponding lengths on both triangles
Triangle ABC Triangle DEF Common ratio
20 40 2
21 42 2
29 58 2
Since the common ratios are the same, then the triangles are similar
Hence, Janette's claim is true

Suppose a radius of a circle is 17 units and a chord is 30 units long. Find the distance from the center of
the circle to the chord.
Answer:
Let A represent the center of the circle. Let the point B be a point at the intersection of the one end of the chord and the edge of the circle. Finally, let C represent a point between the center of the circle and the midpoint of the cord. The triangle ABC is a right triangle with a 90 degree angle at ACB. Since the cord length is 30, the bisected segment BC is length 15 .
(length AB)^2 = (length BC)^2 + (length AC)^2
17^2 = 15^2 + (length AC)^2
289 = 225 + (length AC)^2
add -225 to each side
64 = (length AC)^2
take square root of each side
8 = length AC

A 13 meter long cylinder with a diameter of 6 meters has a square prism with a base length of 3 meters hole going all the way through the center of it as shown in the diagram (not to scale). Find the volume of the composite shape rounding to the nearest cubic meter. Hint: while working the problem carry figures at least three decimal places, then round to the nearest cubic meter only once at the very end.
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

Answer:
d = 90°

Step-by-step explanation:
d + 90° = 180° (Angles in linear pair)
-> d = 180° - 90°
-> d = 90°
e = 41° (vertical angles)
f + 41° = 180° (Angles in linear pair)

Answer:
(-1,1)
Step-by-step explanation:
Answer:
(- 1, 1 )
Step-by-step explanation:
2x - 3y = - 5 → (1)
3x + y = - 2 → (2)
multiplying (2) by 3 and adding to (1) will eliminate y
9x + 3y = - 6 → (3)
add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
substitute x = - 1 into either of the 2 equations and solve for x
substituting into (2)
3(- 1) + y = - 2
- 3 + y = - 2 ( add 3 to both sides )
y = 1
solution is (- 1, 1 )

Find the Volume of the Cuboid whose Length , Breadth and Height are 25 cm , 20 cm and 15 cm .Answer :-
Volume of Cuboid is 7500 cm³ .[tex] \rule {210pt} {2pt} [/tex]
Given :-
Length of Cuboid = 25 cmBreadth of Cuboid = 20 cmHeight of Cuboid = 15 cmTo Find :-
Volume of Cuboid = ?Solution :-
As per the provided information in the given question, Length of Cuboid is 25 cm . Breadth is given 20 cm . Height of Cuboid is given 15 cm . And , we have been asked to calculate the Volume of Cuboid .
For calculating the Volume , we will use Formula :-
[tex] \bigstar \: \: \boxed {\sf { \: Volume \: _{Cuboid} = Length \times Breadth \times Height \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
⇒ Volume = Length × Breadth × Height
⇒ Volume = 25 × 20 × 15
⇒ Volume = 500 × 15
⇒ Volume = 7500
Hence :-
Volume = 7500 cm³ .[tex] \underline {\rule {210pt} {4pt}} [/tex]
⇒ Volume = Length × Breadth × Height
⇒ Volume = 25 × 20 × 15
⇒ Volume = 500 × 15
⇒ Volume = 7500
