Answer:
255.368 tons
Explanation:
Integrate the provided function s(t) = 65 + 24 sin(0.3t) over the interval 2 to 5 (since it is hours since 5:00AM).
There are 67.4 tones to the beach over the 3-hour period from 7:00 a.m. to 10:00 a.m.
To help restore the beach sand is being added to the beach at a rate of s(t) = 65+24sin(.3t) tons per hour, where t is measured in hours since 5:00 a.m.
What we have to determine?We have to determine
How many tons of sand are added to the beach over the 3-hour period from 7:00 a.m. to 10:00 a.m.
According to the question
The beach sand is being added to the beach at a rate.
Where t is measured in hours since 5:00 a.m. The number of tons to the beach over the 3-hour period from 7:00 a.m. to 10:00 a.m. is calculated by substituting the t = 3 in the equation.
The complete length of a shape's boundary is referred to as the perimeter in geometry. The perimeter of a shape is obtained by adding up the length of all the sides and edges of the shape. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
Now, let's assume a geometric system of a square and a parallelogram having the same base and equivalent side of the square " a ". The respective two parallel sides of the Parallelogram will also be equal.
Therefore, the number of tons to the beach over the 3-hour period from 7:00 a.m. to 10:00 a.m. is 7:00 a.m. to 10:00 a.m.

Initially, a ball has an angular velocity of 5.0 rad/s counterclockwise. sometime later, after rotating through a total angle of 5.5 radians, the ball has an angular velocity of 1.5 rad/s clockwise. what is the angular acceleration?
Explanation:
it is not necessary to know for this question, but FYI
1 rad = 180/pi = 57.29577951...°
in essence it describes the arc angle of the arc with the length = radius.
anyway,
we are only dealing with relative sizes here all expressed in radians.
the original spin rate or angular velocity is 5.0 rad/sec.
that means in 1 second it spins by 5 radians (a point on the surface moves by that many degrees).
remember, acceleration is speed/time or distance/time².
then we measure again - after the ball moved by a total angle of 5.5 radians. so, it was longer than 1 second.
so, how much time passed ?
time = distance / speed
5.5 rad / 5.0 rad /1 sec = 1 sec × 5.5 rad / 1×5.0 rad =
= 5.5 sec / 5.0 = 1.1 sec
so, the acceleration was
1.5 - 5.0 = -3.5 rad/(1.1 sec)² = -3.5 rad / 1.21 sec² =
= -2.892561983... rad/sec²

If a concession owner pays $0.50 per pretzel, and it costs the owner $1.00 to have the pretzel prepared and served, what should the owner charge per pretzel if he wants cost to be 60% of the price?
The owner should charge an amount of $2.50 per pretzel, if the cost price of 60% is desired.
What is cost price?The cost borne by a producer to manufacture or produce such goods and sell them at a higher price is known as the cost price. In this case, the cost price if $1.50 per pretzel.
If such cost price is desired to be 60% of the selling price, then the selling price will be,
[tex]\rm Sell\ Price= \dfrac{Cost\ Price}{Desired\ Percentage}\ x\ 100\\\\\rm Sell\ Price= \dfrac{1.50}{60}\ x\ 100\\\\\rm Sell\ Price= \$2.5[/tex]

Altitudes $\overline{ad}$ and $\overline{be}$ of acute triangle $abc$ intersect at point $h$. if $\angle ahb = 128^\circ$ and $\angle bah = 28^\circ$, then what is $\angle hca$ in degrees?
The Angle HCA is equal to 52°. This is arrived at using the knowledge of the Total value of Angles in a Triangle and the Total Value of Angles in a Polygon.
What other principles were used to arrive at the answer?
The other principles of mathematics that were used to arrive at the above answer are:
Total Angles on a straight line; Total Angles on a point; and Line segments.What are the Steps to the Solution?Step 1 - Recall that we have been given Angles AHB and BAH to be 128° and 28° respectively.
We also know that:
The sum of angles in a triangle is 180°;...................AThe sum of angles on a straight line is 180°;.........BThe sum of angles in a polygon is 360°; while.....CThe total sum of angles at a point is 360°.............DSince A...therefore:
When ∠AHB (128°) and ∠BAH are taken from 180° we have DBA = ∠28°.
By observation, we can deduce that ∠BDE, ∠CDH, ∠CEH and ∠AEH are all right-angled triangles.
Using the above, we are able to repeat this process of solving for each angle until we have ∠HCA.
To verify that our answer is correct, recall that sum of angles in a polygon is 360°
That means:
∠BDA + ∠DHE + ∠CEH + ∠HCA = 360°
That is, 90+ 128 + 90 + 52 = 360°
