Hey you!

If I understood your question correctly, here's your answer:

0.93/3 = 0.31

0.31 × 4 = 1.24

So, it would cost $1.24 for 4 packs.

I Really Hope You Found This Helpful!

8.) It takes Fred 9 minutes to type and spell check 13 pages of a manuscript. Find how long it takes him to type and spell check
inysia [295]

It will take Fred 42 minutes to type and spell check 60 pages.

  • Let the first scenario be A.
  • Let the second scenario be B.
  • Let the unknown time be X.

Given the following data;

  • Time taken A = 9 minutes
  • Number of pages A = 13 pages
  • Number of pages B = 60 pages
  • Time taken B = X minutes

To find how long it takes him to type and spell check 60 pages;

We would use direct proportion to express the work described and solve for the unknown variable (time).

9 \;minutes : 13 \;pages\\\\X \;minutes : 60 \;pages

Cross-multiplying, we have;

9 × 60 = 13 × X

540 = 13X\\\\X = \frac{540}{13}

<em>X = 41.54 ≈ 42 minutes</em>

Therefore, it will take Fred 42 minutes to type and spell check 60 pages.

These are so great! They are a perfect combination of Physics and pre-calculus! Your max height of that projectile is going to occur at the max value of the parabola, or at its vertex.  So we need to find the vertex.  The coordinates of the vertex will give us the x value, which is the time in seconds it takes to reach y which is the max height.  Do this by completing the square.  Begin by setting the equation equal to 0 and then moving the 80 over to the other side.  Then factor out the -16.  This is all that: -16( t^{2}-4t)=-80.  Take half the linear term which is 4 and square it and add it in to both sides.  Half of 4 is 2, 2 squared is 4, so add 4 into the set of parenthesis and to the -80.  -16( t^{2}-4t+4)=-80-64. The -64 on the right comes from the fact that when you added 4 into the parenthesis, you had the -16 out in front which is a multiplier.  -16 * 4 - -64.  So what you really added in was -64.  Now the perfect square binomial we created in that process was -16(x-2) ^{2} =-144.  When we move the 144 back over by addition we find that the vertex of the polynomial is (2, 144).  And that tells us that it takes 2 seconds for the projectile to reach its max height of 144 feet.  To find the time interval in which the object's height decreases occurs from its max height of 144 to where the graph of the parabola goes through the x-axis to the right of the max.  To find where the graph goes through the x-axis, or the zeroes of the graph, you factor the polynomial.  When you do that using the quadratic formula you get that x = -1 and 5.  So at its max height it is at 2 seconds, and by 5 seconds it hits the ground.  So the time interval of its height decreasing is from 2 seconds to 5 seconds, or a total of 3 seconds.  I think you need the 2 and 5, from the wording of your problem.

A cell phone company recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June's
hjlf

Answer:

Option A. is correct.

Step-by-step explanation:

Given: A cell phone company recently noticed a 26\% sales decrease in the month of July compared to June such that n represent June's  sales.

Also, y represents July's sales.

To find: equation that can be used to determine the sales in July

Solution:

June's sales =n

Decrease in sales =\frac{26}{100}n=0.26n

So,

July's sales =n-0.26n

Also,

July's sales =y

Therefore,

y=n-0.26n

So, option A. is correct.
