Jasmine wants to organize her books in order of most number of pages to least number of pages. Jasmine's longest book has 396 pages and her shortest book has one-fourth as many pages as the longest. If the book in the middle of her shelf has three times the number of pages of the shortest book. Then how many pages does the middle book have?
Answers
Answer:
297 pages
Step-by-step explanation:
Number of pages of longest book = 396 pages
Now we are given that her shortest book has one-fourth as many pages as the longest.
Number of pages of shortest book = [tex]\frac{\text{Number of pages in longest book}}{4}[/tex]
= [tex]\frac{396}{4}[/tex]
= [tex]99[/tex]
Now we are given that the book in the middle of her shelf has three times the number of pages of the shortest book.
So, Number of pages in middle book:
= [tex]3 \times \text{Number of pages of shortest book}[/tex]
= [tex]3 \times 99[/tex]
= [tex]297[/tex]
Hence the middle book have 297 pages.

How to solve the formula for Vf in the formula of acceleration?
Answers
Multiply by t on both sides to clear the denominator
at = Vf - Vi
Add Vi to both sides.
at +Vi = Vf
Final answer:
To solve for final velocity (Vf) in acceleration calculations, identify the initial velocity (Vo), acceleration (a), and time (t), then use the formula Vf = Vo + at to find Vf. Substitute the known values into the formula to calculate the final velocity.
Explanation:
To solve for final velocity (Vf) in the formula for acceleration, follow these steps:
Identify the initial velocity, Vo, and any other known variables such as acceleration (a) and time (t).
Determine which equation to use, using the relationship that acceleration is the change in velocity over time (Δv/Δt). The formula to calculate final velocity is v = Vo + at.
Substitute the known values into the equation to solve for Vf. For example, with an initial velocity (Vo) of 30.0 km/h (which converts to 8.333 m/s), an unknown final velocity (Vf), and a time (Δt) of 8.00 seconds, the change in velocity (Δv) would be Vf - Vo.
To find Vf, rearrange the equation: Vf = Vo + (a Δt). Insert the known values into the equation and calculate the result.
As an example, if the initial velocity Vo is 0 and the acceleration is 0.40 m/s² over a time of 100 seconds, then the final velocity Vf is calculated as:
Vf = Vo + at = 0 + (0.40 m/s²) (100 s) = 40 m/s.
This procedure will yield the final velocity of an object assuming constant acceleration over the given time period.

You are on a 650-mile trip. your car used eight gallons of gas to travel the first 210 miles of the trip. how much more gas will you need to make it the rest of the way at the same rate?
Answers
The car will need approximately 8.76 more gallons of gas to complete the remaining 440 miles of the 650-mile trip, assuming it continues to get the same mileage rate of 26.25 miles per gallon.
Explanation:To calculate the additional amount of gas needed to complete the 650-mile trip, given that the car used eight gallons to travel the first 210 miles, we need to find the car's mileage rate and then determine how much more gas is required for the remaining distance.
Step-by-Step Explanation
Therefore, the car will need approximately 8.76 more gallons of gas to complete the rest of the trip at the same rate.
To calculate the additional gas needed for the remainder of a 650-mile trip after using 8 gallons for the first 210 miles, first determine the gas mileage and then calculate the gas required for the remaining 440 miles. The car will need approximately 16.76 more gallons of gas to complete the trip.
Explanation:To determine how much more gas you will need to complete your 650-mile trip, after having used 8 gallons for the first 210 miles, you need to calculate your car's gas mileage and then use that information to find the amount of gas needed for the remaining distance.
First, let's compute your car's mileage:
Gas mileage = Distance driven / Gallons of gas usedGas mileage = 210 miles / 8 gallonsGas mileage = 26.25 miles per gallon (mpg)Now, let's subtract the miles you have already traveled from the total trip length to find the remaining miles:
Remaining distance = Total distance - Distance already traveledRemaining distance = 650 miles - 210 milesRemaining distance = 440 milesFinally, we calculate the amount of gas needed for the remaining distance:
Gallons needed = Remaining distance / Gas mileageGallons needed = 440 miles / 26.25 mpgGallons needed = approximately 16.76 gallonsTherefore, you will need approximately 16.76 more gallons of gas to complete your trip, assuming the gas mileage remains consistent.

Find dy/dx by implicit differentiation and evaluate the derivative at the given point.
xy = 35 ...?
Answers
Since that, the first thing you should do is to differentiate with respect to x
(look at the pic. 1), as you can see this is simply 1, which means you have to simplify
Then we need to perform solving for for dy/dx as we are about to get the derivative of y with respect to x. pic.2
Get back to the oroginal function, now we can substitute this for y to get the func which will depend only on x pic.3
Then pic.4
Final answer:
To find dy/dx by implicit differentiation of the equation xy=35, differentiate both sides with respect to x. Use the product rule to obtain x * (dy/dx) + y = 0 and solve for dy/dx, giving dy/dx = -y / x. Evaluate this at a specific point by substituting the x and y values from that point into the derived formula.
Explanation:
To find dy/dx by implicit differentiation of the equation xy = 35, we differentiate both sides of the equation with respect to x. Since y is a function of x, when we differentiate y we must apply the chain rule, resulting in the derivative y with respect to x, or dy/dx.
Starting with the original equation:
xy = 35
We apply differentiation to both sides with respect to x:
Using the product rule for the left side: d/dx (xy) = d/dx (35)
This gives us x * (dy/dx) + y * (1) = 0 because the derivative of a constant, like 35, is 0.
We then solve for dy/dx: dy/dx = -y / x.
To evaluate the derivative at a given point, you substitute the x and y coordinates of that point into the derivative equation. For example, if we are given a point (5,7), we substitute into the dy/dx equation to find the derivative at that point:
dy/dx = -y / x = -(7) / (5)
Therefore, dy/dx at the point (5,7) is -7/5 or -1.4.

= 58x + 13 + 58y
Answer:
Total money Zinnia and Ruby earned for delivering pizzas is 58x + 13 + 58y .
Step-by-step explanation:
As given
Zinnia and Ruby earn $58 per week for delivering pizzas.
Zinnia worked for x weeks and earned an additional total bonus of $13.
Ruby worked for y weeks.
Thus
Money Zinnia earns = Money earns per week × Number of weeks + Additional total bonus .
Put all the values in the above
Money Zinnia earns = 58 × x + 13
Money Zinnia earns = 58x + 13
Thus
Money Ruby earns = Money earns per week × Number of weeks
Put all the values in the above
Money Ruby earns = 58 × y
Money Ruby earns = = 58y
Thus
Total Zinnia and Ruby earned for delivering pizzas = Money Zinnia earns + Money Ruby earns
Total Zinnia and Ruby earned for delivering pizzas = 58x + 13 + 58y
Therefore the total money Zinnia and Ruby earned for delivering pizzas is 58x + 13 + 58y .

corresponding reference angle to 17pi/7
Answers
The corresponding reference angle to 17π/7 radians is π/7.
Explanation:The corresponding reference angle to 17π/7 radians is found by determining the smallest positive angle such that when added to 17π/7 radians, the resulting angle lies between 0 and 2π radians.
To find the reference angle, we can subtract 2π radians repeatedly until we obtain an angle between 0 and 2π radians.
In this case, we have:
17π/7 - 2π = π/7
Therefore, the corresponding reference angle to 17π/7 is π/7 radians.

Answer: Hello there!
I understand the notation 5 1/3 is equivalent to 5 + 1/3 = 5.333...
our equation is 5 +1/3 +(-3 +9/18)
first we could simplify the 9/18 as 1/2 (dividing both numerator and denominator by 9)
then the equation is:
=5+ 1/3 - (3 +1/2)
=5 + 1/3 - 3 - 1/2
=5 -3 + (1/3 - 1/2)
the common factor betwe 3 and 2 is 6, then:
=2 + (2/6 - 3/6) = 2 -1/6
this can be written as:

A spherical balloon is inflated with gas at a rate of 900 cubic centimeters per minute.
(a) How fast is the radius of the balloon changing at the instant the radius is 40 centimeters?
___cm/min
(b) How fast is the radius of the balloon changing at the instant the radius is 90 centimeters? _____ cm/min
...?
Answers
The rate at which the radius of the balloon is changing can be found by differentiating the volume formula for a sphere. Substituting the given values into the formula, we can calculate the rate of change at specific radii.
Explanation:To find the rate at which the radius of the balloon is changing, we can use the relationship between the volume and the radius of a sphere. The volume of a sphere is given by the formula V = (4/3)πr³, where V is the volume and r is the radius. Taking the derivative of both sides with respect to time, we get dV/dt = 4πr²(dr/dt). We are given that dV/dt = 900 cm³/min and we need to find dr/dt when r = 40 cm and r = 90 cm.
(a) Plug in the values into the formula: 900 = 4π(40)²(dr/dt). Solve for dr/dt: dr/dt = 900/(4π(40)²) ≈ 0.178 cm/min.
(b) Repeat the same steps for r = 90 cm: 900 = 4π(90)²(dr/dt). Solve for dr/dt: dr/dt = 900/(4π(90)²) ≈ 0.020 cm/min.

PTG has side lengths of 12 cm, 25 cm, and 19 cm. Which type of triangle is PTG?
right
acute
obtuse
isosceles ...?
Answers
We could calculate at least two angles of the triangle to determine whether it is a right, acute, or obtuse. We need to use the cosine law:
a^2 + b^2 - 2ab * cos C = c^2
cos C = (a^2 + b^2 - c^2) / 2ab
C = arccos((a^2 + b^2 - c^2) / 2ab)
Solving for two angles P and T,
P = arccos((12^2 + 19^2 - 25^2)/(2*12*19))
P = 105.3 degrees.
Since one angle is an obtuse angle, we dont need to compute for the other angle. We can conclude then that the triangle is an obtuse angle.

Write an equation of the line that passes through (−5, −2)(−5, −2) and is parallel to y=23x+1y=23x+1.
Answers
The equation of a line parallel to y=23x+1 that passes through the point (-5, -2) is y = 23x + 113.
Explanation:The subject of this question is geometry, specifically, the formulation of a linear equation. You're asked to write an equation of a line that passes through point (-5,-2) and is parallel to the line defined by the equation y=23x+1.
Parallel lines have the same slope, so since the given line has a slope of 23, our line will also have a slope of 23. The general form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept. Here, 'm' is already known as 23. So, our equation currently is y = 23x + b.
We can determine 'b' using the given point (-5,-2). Substituting these coordinates into our equation gives -2 = 23*(-5) + b. Solving for 'b' renders b = -2 - (23*-5) = 113.
Therefore, the equation of the line that passes through (-5, -2) and is parallel to y=23x+1 is y = 23x + 113.

We must plug in the given value of x in the function and confirm that the value of y that is returned to us is the correct one.
a) (0, 18)
[tex]x=0,y=18[/tex]
[tex]y = 16 + 0.5(0)=16+0=16[/tex]
the values for y do not match, so it is not a solution.
b) (5, 19.5)
[tex]x=5,y=19.5[/tex]
[tex]y = 16 + 0.5(5)=16+2.5=18.5[/tex]
again, the values for y do not match so it is not a solution.
c) (8, 20)
[tex]x=8,y=20[/tex]
[tex]y = 16 + 0.5(8)=16+4=20[/tex]
For this option, the values of y do match, so (8, 20) are the missing values.
