Darren filled boxes with tins of Orange juice and numbered the boxes in the order in which they were filled. He packed the 496th tin in box 21 then stopped for lunch. Box 21 was not completely filled. How many tins were in box 21?
Answer:
16
Step-by-step explanation:
Darren completely filled each box before the 21st box. This means he completely filled 20 boxes. To find out how many tins fit in each box, divide:
496/20 = 24.8
This means each of the 20 preceding boxes held 24 tins. To get these filled, Darren used 20(24) = 480 tins of juice.
This left Darren with 496-480 = 16 tins of juice to put in box 21 before lunch.
Final answer:
To find out how many tins are in box 21, we subtracted the number of tins contained in the first 20 fully packed boxes from the total number of tins Darren packed. We found that each of the first 20 boxes must contain 24 tins, hence, there are 16 tins in the partially filled box 21.
Explanation:
The student's question is about finding how many tins were in box 21 before Darren stopped for lunch. To determine this, we need to figure out the pattern of how the tins were packed into the boxes. Since Darren packed the 496th tin in box 21, and since box 21 is not completely full, we can start by assuming that each box before box 21 was filled completely. If we can find the number of tins each box can hold, we will know the number of tins in box 21.
Let's assume the number of tins each box can hold is x. Since 20 boxes are completely full, they would contain a total of 20x tins. Box 21 contains fewer than x tins. The total number of tins, including those in box 21, is 496. Thus, we have the equation 20x + (496 - 20x) = 496. Simplifying, we get 20x = 496 - (496 - 20x), leading to 20x = 20x, which means each of the first 20 boxes contains the same number of tins. To find x, we need to divide the total number of tins not including box 21 by 20. Now we subtract that product from 496 to find the number of tins in box 21.
Since 496 is not evenly divisible by 20, we find that x is a decimal, which is not possible since we cannot have a fraction of a tin. Therefore, we subtract 1 from 496 to make it divisible by 20, giving us 495 tins to be divided evenly among the 20 full boxes. So, 495 ÷ 20 = 24.75, which means each full box holds 24 tins (since we can't have a fraction of a tin). Therefore, the number of tins in box 21 is 496 - 20*24 = 496 - 480 = 16 tins.

For the angles α and β in the figures, find cos(α + β)?
Answer:
[tex]\cos(\alpha +\beta)=\frac{2}{3}(1-\frac{\sqrt{5}}{5})[/tex]
Step-by-step explanation:
Let the hypotenuse of the smaller triangle be h units.
Then; from the Pythagoras Theorem.
[tex]h^2=4^2+2^2[/tex]
[tex]h^2=16+4[/tex]
[tex]h^2=20[/tex]
[tex]h=\sqrt{20}[/tex]
[tex]h=2\sqrt{5}[/tex]
From the smaller triangle;
[tex]\cos (\alpha)=\frac{4}{2\sqrt{5} }=\frac{2}{\sqrt{5} }[/tex] and [tex]\sin(\alpha)=\frac{2}{2\sqrt{5} }=\frac{1}{\sqrt{5} }[/tex]
From the second triangle, let the other other shorter leg of the second triangle be s units.
Then;
[tex]s^2+4^2=6^2[/tex]
[tex]s^2+16=36[/tex]
[tex]s^2=36-16[/tex]
[tex]s^2=20[/tex]
[tex]s=\sqrt{20}[/tex]
[tex]s=2\sqrt{5}[/tex]
[tex]\cos(\beta)=\frac{2\sqrt{5} }{6}=\frac{\sqrt{5} }{3}[/tex]
and
[tex]\sin(\beta)=\frac{4}{6}=\frac{2}{3}[/tex]
We now use the double angle property;
[tex]\cos(\alpha +\beta)=\cos(\alpha)\cos(\beta) -\sin(\alpha)\sin(\beta)[/tex]
we plug in the values to obtain;
[tex]\cos(\alpha +\beta)=\frac{2}{\sqrt{5} }\times \frac{\sqrt{5} }{3}-\frac{1}{\sqrt{5} }\times \frac{2}{3}[/tex]
[tex]\cos(\alpha +\beta)=\frac{2}{3}(1-\frac{\sqrt{5}}{5})[/tex]
Answer:
[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]
Step-by-step explanation:
Little triangle.We know both legs, we can use the tangent trigonometric reason to find the angle.
[tex]tan\alpha =\frac{2}{4}\\ tan \alpha=\frac{1}{2}\\ \alpha=tan^{-1}(\frac{1}{2} )\\ \alpha \approx 26.6\°[/tex]
Larger triangle.We know the hypothenuse and the opposite leg. We can use the sin trigonometric reason to find the angle
[tex]sin\beta =\frac{4}{6}\\ sin\beta=\frac{2}{3}\\ \beta=sin^{-1} (\frac{2}{3} )\\\beta= 41.8\°[/tex]
So, the sum of them is
[tex]\alpha + \beta = 26.6+41.8= 68.4\°[/tex]
Then,
[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]
Therefore,
[tex]cos(\alpha + \beta)=cos(68.4\°) \approx 0.37[/tex]
what is measure of angle R?

The measure of angle R is 30 degrees.
To determine the measure of angle R, we can use the properties of special right triangles, specifically the 30-60-90 right triangle. In such a triangle, the angles are 30 degrees, 60 degrees, and 90 degrees, and the lengths of the sides opposite these angles are in the ratio 1:√3:2, respectively.
Given that side PR is the hypotenuse of the right triangle PQR and it is 2 units long, we can deduce that triangle PQR is a 30-60-90 triangle. The side QR, which is opposite the 30-degree angle at Q, is half the length of the hypotenuse. Since PR is 2 units, QR must be 1 unit.
The side PQ is opposite the 60-degree angle at P and is 3 times the length of QR. Since QR is 1 unit, PQ must be 3 units.
The angle R is opposite the side PQ, and since we have established that PQR is a 30-60-90 triangle, angle R must be the smallest angle, which is 30 degrees.
Therefore, the measure of angle R is 30 degrees.

Robert is in charge of a community swimming pool. Each sprig he drains it in order to clean it. Then he refills the pool, which holds 120,000 gallons of water. Robert fills the pool at a rate of 10 gallons each minute. What is the rate at which Robert will fill the pool? Is it constant? Write an equation for the direct variation.
Answer:
It is constant (10 gallons a minute)
120,000/10 = 12,000
12,000 minutes to fill the pool
120,000 - 10x
Step-by-step explanation:
Answer:
The pool holds 120,000 gallons of water.
Robert fills the pool at a rate of 10 gallons each minute.
That means for filling 120000 gallons, he will need = [tex]\frac{120000}{10}[/tex] = 12000 minutes
If we convert this to hour, then in 1 hour, [tex]10\times60[/tex] = 600 gallons can be filled.
So, the rate in gallons per hour = [tex]\frac{120000}{600}[/tex] = 200 gallons per hour.
Therefore, the rate at which Robert will fill the pool is 200 gallons per hour.
Yes the rate is constant.

What are mathematics operations?
A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.
• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.
Here, it is given that :
Ellie read 30 pages of her social studies book in 1.5 hours at a constant rate, let first find Ellie's social studies reading rate :
rate = 30 pages/1.5 hours = 20 pages/ hr.
Now, to find out the unit rate, divide the total number of pages reading novel by the total time spent.
rate = 150 pages/ 2 hours = 75 pages/ hr.
To find out the percentage divide Ellie's novel reading rate by Ellie's social studies reading rate and multiply by 100
percent of Ellie’s social studies reading rate is her Novel reading rate = 75/20 x 100 = 375%.
Therefore, percent of Ellie’s social studies reading rate is her Novel reading rate is 375%.

A tourist traveled on a motorboat against the current for 25 km. And then returned back on a raft. In the boat the tourist traveled for 10 hours less than on the raft. Find the speed of the current if the speed of the motorboat in still water is 12 km/hour.
Answer:
2 km/h
Step-by-step explanation:
Let x km/h be the speed of the current.
1. A tourist traveled on a motorboat against the current for 25 km (the current interfered), then it took him
[tex]\dfrac{25}{12-x}\ hours.[/tex]
2. Then he returned back on a raft (the speed of the current is the speed of the raft), then it took him
[tex]\dfrac{25}{x}\ hours.[/tex]
3. In the boat the tourist traveled for 10 hours less than on the raft, thus
[tex]\dfrac{25}{12-x}+10=\dfrac{25}{x}.[/tex]
Solve this equation:
[tex]25x+10x(12-x)=25(12-x),\\ \\25x+120x-10x^2=300-25x,\\ \\10x^2-170x+300=0,\\ \\x^2-17x+30=0,\\ \\D=(-17)^2-4\cdot 30=289-120=169,\\ \\x_{1,2}=\dfrac{-(-17)\pm\sqrt{169}}{2}=2,\ 15.[/tex]
The speed of the current cannot be greater than the speed of the boat, because then tourist was not able to travel against the current. Thus, the speed of the current is 2 km/h.

The coordinates of points M,N, and P are ....
Answer:
(-1, -1) Let me know if the explanation didn't make sense.
Step-by-step explanation:
If we graph the three points we can see what looks like a quadrilateral's upper right portion, so we need a point in the lower left. This means M is only connected to N here and P is only connected to N. So we want to find the slope of these two lines.
MN is easy since their y values are the same, the slope is 0.
NP we just use the slope formula so (y2-y1)/(x2-x1) = (-1-3)/(5-4) = -4.
So now we want a line from point M with a slope of -4 to intersect with a line from point P with a slope of 0. To find these lines weuse point slope form for those two points. The formula for point slope form is y - y1 = m(x-x1)
y-3 = -4(x+2) -> y = -4x-5
y+1 = 0(x-5) -> y = -1
So now we want these two to intersect. We just set them equal to each other.
-1 = -4x -5 -> -1 = x
So this gives us our x value. Now we can plug that into either function to find the y value. This is super easy of we use y = -1 because all y values in this are -1, so the point Q is (-1, -1)

In the figure, KT and KY are tangent segments to circle O. Find KT and OY. You must show your work. Someone please help me out !!!
Answer:
KT = 60
OY = 11
Step-by-step explanation:
Remember that the tangent to a circle theorem states that if a line is tangent to a circle, it is perpendicular to the radius at the point of tangency. Which means angles OTK and OYK are right angles.
If OTK and OYK are right angles, triangles KOT and KYO are right triangles. Since KOT is a right triangle, we can use the Pythagorean theorem to find KT:
[tex]hypotenuse^2=leg^2+leg^2[/tex]
[tex]KO^2=KT^2+OT^2[/tex]
[tex]61^2=KT^2+11^2[/tex]
[tex]KT^2=61^2-11^2[/tex]
[tex]KT=\sqrt{3600}[/tex]
[tex]KT=60[/tex]
Now, remember that the "hat" theorem states that tangents to a circle from the same external point are congruent, so KT and KY are congruent.
The Hypotenuse-Leg theorem states that if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg another right triangle, then the triangles are congruent. The hypotenuse, KO, of both right triangles are the same (therefore congruent) and legs KT and KY are congruent by the hat theorem, therefore triangles KOT and KYO are congruent. Since corresponding parts of congruent triangles are congruent, OY ≅ OT.
OY = OT = 10
OY = 10
Let's summary the above in a short proof:
1. ∠OTK and ∠OYK are ∟ angles Tangent to a circle theorem
2. ΔOTK and ΔOYK are ∟ triangles Definition of right triangles

The form he builds is 40 1/2 in. long, 10 in. deep, and 8 in. high. How much cement is needed to fill the form
This question clearly states that it is a 'find the volume' question.
Given dimensions of the object are :
Length of the object = [tex]40\frac{1}{2}[/tex] inches or 40.5 inches
Depth of the object = 10 inches
Height of the object is = 8 inches
So, the volume becomes = [tex]40.5\times10\times8[/tex] = 3240 cubic inch
Hence, the amount of cement needed is 3240 cubic inches.
To fill the form, you use the formula for the volume of a rectangular prism (length x width x height) to find that 3240 cubic inches of cement is needed.
The student is asking about the volume of cement needed to fill a form with specified dimensions. To calculate the volume, we need to use the formula for the volume of a rectangular prism, which is length x width x height. In this case, we need to convert the mixed number into an improper fraction before multiplying, or we could convert it to a decimal.
First, convert the length from 40 1/2 inches to 40.5 inches. Then, use the formula:
Volume = length x width x height
Volume = 40.5 in x 10 in x 8 in
Volume = 405 in x 8 in
Volume = 3240 cubic inches
Therefore, to fill the form, 3240 cubic inches of cement is needed.
