The equation that represent the number of days it will take phoebe to finish the novel is: x= number of pages left to be read / pages to be read per day
Information about the problem:
novel’s pages = 368read pages = 53pages to be read per day = 35 pages/daynumber of days it will take phoebe to finish the novel = x ?To solve this problem, we have to write the equation in order to calculate (x) the number of days it will take phoebe to finish the novel with the given information:
number of pages left to be read = novel’s pages - read pages
number of pages left to be read = 368 – 53
number of pages left to be read = 315 pages
Knowing the number of pages left to be read we can write the following equation:
x = number of pages left to be read / pages to be read per day
x = 315 pages /35 pages/day
x = 9 days
What is an equation?An equation is the equality between two algebraic expressions, which have at least one unknown or variable.

If two coplanar lines are cut by _________ so that a pair of alternate interior angles are _,_____ then the two lines are parallel.
If two coplanar lines are cut by a transversal so that a pair of alternate interior angles are equal then the two lines are parallel.
The four sets of opposing angles that each have their own vertex point, are on different sides of the transversal and are both either internal or exterior are called alternate angles.
In geometry, a transversal line is one that cuts across the plane in two places. It does so at two spots where two lines meet. Many right angles are produced when two transverse lines meet. There are four types of similar angles: matching, alternative interior, alternate exterior, and co-interior.
In geometry, two lines are considered parallel if and only if all pairs of alternative interior angles in any transversal are equal.

Does the orientation of the vertices change or stay the same after a reflection?
The orientation of the vertices stay same after a reflection.
The orientation of the vertices is nothing but The relative arrangements of points following a transformation or after surrounding a geometric shape are known as orientation. In terms of how the points align, orientation is divided into clockwise and counterclockwise. The points are opposite the original shape when the orientation is reflected. Same orientation denotes that the points are simply a reflection of the original figure and are arranged in exactly the same manner.
The orientation of the vertices stay same after a reflection.
When you translate a figure, you slide it left, right, up, or down. This implies that the coordinates for the vertices of the figure will alter on the coordinate plane.
Apply the same change to each point to graph a.
The variations in a reflection's coordinates can be used to identify it. The figure makes a mirror image of itself when it flips across a line in a reflection. Consider the reflection in the image.
Therefore, The orientation of the vertices stay same after a reflection.

The function y=3√-x-3 is graphed only over the domain of {x 1-8 ≤x≤ 8). is the range of the graph is b) {y : -5 < x < - 1 }
Range is set of Y values for which the function is define.
So, in order to find the range , we need to find the corresponding y values for given domain.
Put x = -8 in y = ∛-x -3 then we get,
y = ∛-x -3
y = ∛-(-8) -3
y = ∛8 -3
y = 2 -3
y = - 1
Put x = 8 in y = ∛-x -3 then we get,
y = ∛-(8) -3
y = ∛-8 -3
y = -2 -3
y = - 5
Hence the range of function y = ∛-x -3 over the domain of {x : -8 < x < 8 } is

Determine the values of y in the equation y2 = 121.
due in 1 hour please help
Answer:
y = 60.5 or 11
Step-by-step explanation:
If this is intended to be 2y = 121 (2 times y), that would mean the answer would be 60.5.
This is because you’d divide both sides by 2, resulting in y = 60.5.
However, should this be intended as [tex]y^{2}[/tex]= 121, the answer would be 11.
What we do to find the pure equivalent of y is square root both sides as y is squared.
[tex]\sqrt{y^{2} } = \sqrt{121}[/tex]

Step 3: Apart from this, you can also calculate your time period involved, principal amount and interest amount paid in a specific time period if you have other inputs available with you. Calculate interest amount paid in a specific time period, I = Prt
Answer:
918.50 in interest over 11 years.
Step-by-step explanation:
Comment
You have to make an assumption here. The assumption is that this is simple interest.
So if the brother pays 10% each year, he is paying
10/100 * 835 each year in interest
10/100 * 835 = 83.50 every year.
There are 11 years, so the total interest paid is 11 * 83.50 = 918.50 dollars in total.. That's more than what he borrowed!
ABCD is a rectangle. Find angles a and b, giving reasons with each step.
Answer:
a = 45°b = 23°Step-by-step explanation:
If I name the centre (intersection of diagonals) as O, Angle AOD will be equal to 68°
[Opposite angles are equal]
The diagonals bisect the 4 corner angles of a rectangle in equal halves. So, a = 45°
Also, Angle ADO = 90° - b
[Each of the four angles in a rectangle = 90°]
And In [tex]\triangle[/tex] AOD,
=> Angle AOD + Angle ADO + Angle OAD = 180°
=> 68° + 90° - b + 45° = 180°
=> 203° - b = 180°
=> b = 23°
