Phoebe is reading a novel for her monthly book club. the novel is 368 pages long. so far, she has read 53 pages. phoebe plans to read 35 pages a day. write an equation that represented, the number of days it will take phoebe to finish the novel
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

Two similar cylinders have heights of 35 meters and 25 meters. What is the ratio of the volume of the large cylinder to the volume of the small cylinder?
The ratio of the volumes of two similar cylinders with heights of 35 meters and 25 meters, respectively, is 2.744.
Solids of the same type that have proportional corresponding linear
measures are similar solids. In the case of similar cylinders:
height of A/ height of B = radius of A/radius of B
If two solids are similar, then the ratio of their volumes is equal to the cube of the ratio of their corresponding linear measures.
volume of A/ volume of B = (height of A/ height of B)^3 = (radius of A/radius of B)^3
If two similar cylinders have heights of 35 meters and 25 meters, then the ratio of the volume of the large cylinder to the volume of the small cylinder is:
height of larger cylinder / height of smaller cylinder = 35 meters / 25 meters = 7/5
volume of larger cylinder/ volume of smaller cylinder = (height of larger cylinder / height of smaller cylinder)^3 = (7/5)^3 = 2.744

The length of the rectangle is three times its width. If the perimeter of the rectangle is one hundred and sixty meters, find the length and width of the rectangle. Enter two integers
Answer:
Please give brainliest if it applies!
w = 20m
l = 60m
Step-by-step explanation:
P = 2l + 2w
We know the perimeter = 160 and we know that l = 3w, so write what we know and solve for w.
P = 2l x 2w
160 = 2(3w) + 2w
160 = 6w + 2w
160 = 8w
Divide both sides by 8
20 = w
Now we can figure out the length, which is 3(w) or 3 x 20 = 60

Blake is setting up his tent at a renaissance fair. If the tent is 8 feet tall, and the tether can be staked no more than two feet from the tent, how long should the tether be?
The tether should be 8.5 feet long.
In this question,
Blake is setting up his tent at a renaissance fair.
The tent is 8 feet tall, and the tether can be staked no more than two feet from the tent.
The stake, height and tether length of the tent form a right angle triangle where the tether length is the hypotenuse.
Applying Pythagoras theorem:
length² = height² + (stake distance)²
length = √(8² + 2²)
length = 8.5 feet
Therefore, the tether should be 8.5 feet long

Rules for expressions with fractions:
Fractions - use a forward slash to divide the numerator by the denominator, i.e., for five-hundredths, enter 5/100. If you use mixed numbers, leave a space between the whole and fraction parts.
Mixed numerals (mixed numbers or fractions) keep one space between the integer and
fraction and use a forward slash to input fractions i.e., 1 2/3 . An example of a negative mixed fraction: -5 1/2.
Because slash is both signs for fraction line and division, use a colon (:) as the operator of division fractions i.e., 1/2 : 1/3.

a. If T U=14 feet, what is the radius of ®Q ?
If TU = 14 feet, then the radius of the circle is 7 feet.
What is meant by radius?
The radius of a circle is the distance between the circle's center and any point on its circumference. It is usually represented by the letters 'R' or 'r'.
A radius of a circle or sphere is any of the line segments from its center to its perimeter in classical geometry, and in more modern usage, it is also their length.
Simply dividing the circle's diameter in half yields the radius formula. If we connect the points on the circle's circumference to the exact center.
Let the radius of the circle be TU = 14 feet
Radius of the circle = c/2
Where, c = 14 then substitute the value in the above equation, then
r = 14/2
r = 7 feet
Therefore, the radius of the circle is 7 feet.

Solve each system by elimination.
3u+3v = 15 , -2u+3v = -5
By elimination, the solution of the system of equations, 3u + 3v = 15 and -2u + 3v = -5, is (u , v) = (4 , 1).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in u and v, a variable should be eliminated by adding/subtracting the two equations.
Subtracting the two equations will eliminate the variable v.
3u + 3v = 15 (equation 1)
-2u + 3v = -5 (equation 2)
5u = 20
u = 4
Substitute the value of u to any of the two equations and solve for v.
3u + 3v = 15 (equation 1)
3(4) + 3v = 15
3v = 15 -12
3v = 3
v = 1
Hence, the solution of the system of equations is (u , v) = (4 , 1).

The equation that could be used to prove the lines are parallel is: D. (c - a)/b = d/e
What are Parallel Lines?Parallel lines are lines that do not converge at any point and have the same slope.
Slope (m) = change in y / change in x
Slope of the first line = (c - a)/0 - b
Slope of the first line = (c - a)/b
Slope of the second line = (0 - (-d))/(e - 0)
Slope of the second line = d/e
Thus, if both line are parallel, then (c - a)/b = d/e. This is because parallel lines have the same slope.

What are proportions?Proportion, in general, is referred to as a part, share, or number considered in comparative relation to a whole. The proportion definition says that when two ratios are equivalent, they are in proportion. It is an equation or statement used to depict that two ratios or fractions are equal.
Let the number of gallons of water needed for 280 million cars be x.
Now, 90 : 500,000 :: 280 : x
⇒ 90x=500,000 × 280
⇒ x = 14,00,00,000/90
⇒ x = 1,555,555.555≈1,555,556 gallons

Vertical Angle Theorem
30=6x
5=x
Answer:
x=5
Step-by-step explanation:
Hello! No worries, Geometry is very confusing.
There are several proofs and theorems to use when trying to prove an angle size. In this picture, we see two lines intersecting, forming an intersection point with two similar looking angles.
With the Vertical Angles Theorem, it explains that when two lines intersect such as shown here, the angle on the vertical side of the original angle are both equal to the same number and is identical. Similarly, using this theorem we know that the unnamed angles (the big ones) are identical too, as they are vertical sides of each other.
Now we know the angle 6x and 30 degrees are equal to each other. So how do we solve x?
We can solve for x by making it equal to each other, signaling that you understand the Vertical Angle Theorem and stating that those two angles are equal to each other.
6x=30 Divide by 6 both sides to isolate the x varianle
x=5
Therefore, x is equal to 5.

Suppose you have an outdoor pool measuring 25 ft by 10ft . You want to add a cement walkway around the pool. If the walkway will be 1 ft thick and you have 304 ft³ of cement, how wide should the walkway be?
The area covered by the pool and the cement walkway is 304 square feet. The width of the walkway would be 5 feet
What is the area of the rectangle?The area of the rectangle is the product of the length and width of a given rectangle.
The area of the rectangle = length × Width
Let x be represent the width of the walkway.
The pool measures 25 ft by 10ft . If the walkway must have a uniform width around the entire pool, then the total length of the pool and the walkway = 25+ x + x = 25 + 2x
The total width of the pool and the walkway = 10 + x + x = 10 + 2x
The area covered by the pool and the cement walkway is 304 square feet. This means that;
(25 + 2x)(10 + 2x) = 304
250 + 50x + 20x + 4x^2 = 304
4x^2 + 70x + 250 - 304 = 0
4x^2 + 70x - 54 = 0
x(x + 20) - 5(x + 20) = 0
(x - 5)(x + 20) = 0
x = 5 or x = - 20
Thus The width cannot be negative.
Therefore, the width of the walkway is 5 feet.
