Let's say c is the cost of the cantaloupe, and that p is how many pounds the cantaloupe weights.
In that case, $1.19 is the amount of money it will cost per pound of cantaloupe.
If the cantaloupe you buy is 3.5 pounds, it will cost you $4.165, but since money is only two decimal places, and since you can only round up when it's a 5 at the end, it becomes $4.17.
In other words, each pound of cantaluope you buy will cost you $1.19, and a cantaloupe that weighs 3.5 pounds will cost you $4.17.
A large cargo ship dropped anchor in the ocean. The anchor was released at a constant rate rate of speed from a height of 44 meters
Answer:
C and E
Step-by-step explanation:
The change in elevation was 44 + 20 = 64 m
the rate of fall was 64 m / 32 s = 2 m/s
The anchor reached the surface in 44 / 2 = 22 s so C is valid
E is correct as the ocean surface is origin and Up is the positive direction.
The anchor starts at 44 m above the surface and position is lower by 2 meters every second
From the question, the two correct options about the speed with which the anchor was released are:
Option COption EHow to solve for the solutionFirst we have to calculate the change that occurred in the elevation. Initially it was 44 meters but dropped 20 m below water.
44 + 20 = 64 meters
Next we calculate the rate with which the fall occurred
The time with which it fell was 32 seconds. = 64/32 = 2 meters pers second
44/2 = 22 hence it can be concluded that C is right.
Option E is also correct given that the water surface is above the ground and it is positive

Solve the inequality, write the answer in interval notation.
9514 1404 393
Answer:
(-∞, 2-√7) ∪ (2+√7, ∞)
Step-by-step explanation:
The factored form of a polynomial is helpful for solving related inequalities. For quadratics with two real zeros, the sign changes at each zero. If the leading coefficient is positive, the sign is positive to for x-values "outside" either zero, and is negative between the zeros.
Your inequality can be written in standard form as ...
x² -4x -3 > 0
x² -4x +4 -7 > 0
(x -2 -√7)(x -2 +√7) > 0 . . . . . factor the difference of squares (x-2)² -7
The zeros are at x=2-√7 and x=2+√7, so the product of these factors will be positive for x < 2-√7 and x > 2+√7. The solution in interval notation is ...
(-∞, 2-√7) ∪ (2+√7, ∞)
_____
Additional comment
We suspect a typo in the problem statement. If it were to read ... > -3, then the zeros would be at 1 and 3, and the solution would be (-∞, 1)∪(3, ∞).

Charlie ate ¾ cup dry food for breakfast and another ½ cup for dinner. If the food
has a caloric density of 360kcal/cup, how many kcal did Charlie eat in total? Please show work!
Answer: 450 kcal
Step-by-step explanation:
So you know the food is 360 kcal per 1 cup
by setting up a proportion, you can relate the number of kcal to cups.
[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(3/4 +1/2)cup} \\\\[/tex]
we can simplify the fraction to this:
[tex]\frac{360 kcal}{1 cup} = \frac{?kcal}{(5/4)cup} \\\\[/tex]
by cross multiplying you can solve the proportion
(360) * (5/4) = (?) * (1)
simplifying gets this:
450 = ?
so he ate 450 kcal total
Cecilia set a goal to raise $4,800.00 for her favorite charity this year. She has decided to participate in a walk-a-thon to help her reach her goal. She found 30 sponsors and each sponsor has agreed to give her $0.50 for each mile that she walks in the walk-a-thon. If she walks a total of 25 miles, how much money will she still need to raise in order to reach her goal for this year?

0.04 with 4 repeating as a fraction. Not the 04 repeating just the 4 is repeating. What is the answer???
Answer:
2/45
Step-by-step explanation:
0.04... is the same as 0.1 * 0.4... because we are moving it up a decimal place, it's the same as multiplying by ten: we needed to multiply by a tenth to cancel that out. 0.4... is the same as 4/9 and 0.1 is the same as 1/10. We can rewrite the expression above as: [tex](\frac{1}{10} )(\frac{4}{9} )[/tex]. Multiplying the two fractions results in 4/90 which can be simplified to 2/45.
The speed of a bus weighing 2000 kg increases from 50 mls to 60 m/s in 4 s. Calculate the change in its momentum and the Force applied on it
Answer:
Momentum = 20 000 kgm/s
Force applied = 5000 N
Step-by-step explanation:
Momentum = Mass * Velocity
= 2000 kg * 10 m/s
= 20 000 kgm/s
Force = Mass * Acceleration
Acceleration = v - u / t
= 60-50/4
= 10/4
= 2.5 m/s^2
F = m*a
= 2000 * 2.5
= 5 000 N

Need help with the second part ASAP.

Answer:
1/x = (1+√5)/2 ≈ 1.618034
Step-by-step explanation:
Since you are only interested in the second part, we presume you have solved the quadratic equation to find ...
x = (√5 -1)/2 ≈ 0.618034
The second part asks for 1/x. The usual method for rationalizing the denominator will be useful for this. Multiply numerator and denominator by the conjugate of the denominator.
[tex]\dfrac{1}{x}=1\div\dfrac{\sqrt{5}-1}{2}=1\times\dfrac{2}{\sqrt{5}-1}\\\\=\dfrac{2(\sqrt{5}+1)}{(\sqrt{5}-1)(\sqrt{5}+1)}=\dfrac{2\sqrt{5}+2}{5-1}=\boxed{\dfrac{\sqrt{5}+1}{2}\approx1.618034}[/tex]

19) The supplement of an angle is 24° more than
the angle. What is the measure of the angle?
1) 7.50 2) 66°
3) 78°
4) 33°
9514 1404 393
Answer:
3) 78°
Step-by-step explanation:
Let x represent the angle. Then 180-x is its supplement, and the difference is ...
(180 -x) -x = 24
90 -x = 12 . . . . . . . divide by 2
x = 90 -12 = 78 . . . . degrees
The measure of the angle is 78°.
The measure of an exterior angle at C of isosceles triangle ABC is 110 degrees. If AC = BC, fine the measure of each angle of the triangle.
Answer:
110°, 35° and 35°
Step-by-step explanation:
Sum of internal angles of a triangle always is 180°
then,
180° - 110° = 70°
and it's an isosceles triangle, the other two angles are equals to 35° (70° / 2)
