Answer:
If we arrange the boxes in rectangular form, there would fit 227 boxes, approximately.Step-by-step explanation:
If we arrange the boxes in a rectangular form, it'd fit 227 boxes, approximately. We deduct this by comparing the volume of the empty space and the volume of each box.
Empty space.[tex]V= 245cm \times 250 cm \times 890 cm = 54,512,500 \ cm^{3}[/tex]
Each box volume.[tex]V_{box} =50cm \times 60cm \times 80cm = 240,000 \ cm^{3}[/tex]
We divide these volumes to find the number of boxes
[tex]n=\frac{54,512,500 \ cm^{3} }{240,000 \ cm^{3} } \approx 227[/tex]
Therefore, if we arrange the boxes in rectangular form, there would fit 227 boxes, approximately.
What is the value of x?
Answer: x = 9, y = 5
Step-by-step explanation:
If all of the sides are equal, it is an equilateral triangle. Equilateral triangles are also equiangular. The angles of a triangle add up to 180 degrees, so each angle must equal 60 degrees.
set the equation equal to 60 to solve for x
7x - 3 = 60
add three to both sides
7x = 63
divide both sides by 7
x = 9
find y by setting the equation equal to 60
11y + 5 = 60
subtract 5 from each side
11y = 55
divide both sides by 11
y = 5
What amount to the nearest cent will an account have after 6 years is $175 is invested at 8% interest compounded continuously
Answer:
$281.02
Step-by-step explanation:
P=$175
r=8%=0.08
t=6 years
n=12
A=p(1+r/n)^nt
=175(1+0.08/12)^12×6
=175(1+0.0066)^72

=$281.015
Approximately $281.02

Answer:
First on is 0.75
Second is 22/52 (not sure about this one though)
Step-by-step explanation:
For the first one:
P(aUb) = p(a) + p(b) - p(a^b)
0.6 = 0.4 + 0.5 - p(a^b)
p(a^b) = 0.3
P(a/b)= p(a^b)/p(a)
P(a/b)= 0.3/0.4
P(a/b)= 0.75
For the second one:
Total of the cards are 52
Diamonds are 13 out of that 52
Face cards are 12 out of that 52
Diamond OR face cards means p(aUb)
And that equals p(a)+p(b)-p(a^b)
p(a^b) means the intersection between the two, there are three common cards between diamonds and face cards, so p(a^b)=3
13/52 + 12/52 - 3/52= 22/52

A flagpole casts a shadow that is 30 feet long A sign Post near the flagpole is 4 feet tall and cast a shadow that is 6 feet long how tall is the flagpole
Answer:
20 ft
Step-by-step explanation:
Given;
Length of flagpole shadow = 30 ft
Sign post height = 4 ft
Length of sign post shadow = 6 ft
Since the two objects are close to each other (the same location)
The height and shadow length of the two objects follows the same ratio, just like similar triangles;
Using the Ratio or similar triangles Formula;
height of flagpole/flagpole shadow length = height of sign post/ sign post shadow length
Substituting the values;
h/30 = 4/6
h = 4/6 × 30 = 20 ft
Flagpole height = 20 ft

Select the correct answer. Segment KL is a diameter of circle Q. Circle Q is represented by the equation (x − 11)2 + (y + 15)2 = 7. What is KL? A. B. C. D.
Answer:
2√7
Step-by-step explanation:
Mathematically, the equation of a circle can be represented by;
(x-h)^2 + (y-k)^2 = r^2
where (h,k) = center and r = radius
Applying this to the question, we can see that the length of the radius of the circle is √7
The diameter is always twice the radius
Thus, the diameter KL = 2 * √7 = 2√7

Un grupo de amigos toman un refresco cada uno y deben pagar 9 € por el total de las consumiciones. Como hay dos que solo pueden poner 1 €, los demás deben aumentar su aportación en 0,25 € cada uno. ¿Cuántos amigos son?
Answer:
6 friends (4 pay € 1.75 and 2 pay € 1)
Step-by-step explanation:
We have to:
x = friends
y = payment
x * y = 9
y = 9 / x
It follows from the problem:
(x-2) * (y + 0.25) = 9 - 2
(x-2) * (9 / x + 0.25) = 7
x * 9 / x + 0.25 * x - 2 * 9 / x - 2 * 0.25 = 7
9 + 0.25 * x - 18 / x - 0.5 = 7
multiply by 100
100 * 0.25 * x - 100 * 18 / x + 100 * (9 - 0.5 - 7) = 0
25 * x - 1800 / x + 150 = 0
multiply by x
25 * x ^ 2 + 150 * x - 1800 = 0
we factor:
(x - 6) * (x + 12) = 0
x = 6
x = -12
The positive value is taken: x = 6
Each one had to pay = 9/6 = € 1.5
But as two pay € 1, 4 will pay € 0.25 more: 1.5 +0.25 = € 1.75
Thus :
(4 * 1.75) +2 (1) = € 9
Therefore, they are 6 friends (4 pay € 1.75 and 2 pay € 1)
Which of the following is the graph of y = cosine (2 (x + pi))?

On a coordinate plane, a curve crosses the y-axis at (0, negative 1). It has a minimum of negative 1 and a maximum of 1. It goes through 1 cycle at pi.
On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 1 cycle at 4 pi.
On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi.
On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi.
Which is the graph of the given function?Here we have the function:
y = cos(2*(x + pi))
First, let's distribute the product in the argument of the cosine:
y = cos(2x + 2pi).
Now, notice that 2pi is the period of a cosine function, then:
cos(2x) = cos(2x + 2pi)
Then we can write:
y = cos(2x)
Now, the y-intercept is:
y = cos(2*0) = 1
And because the factor of 2 inside the argument, it goes through 2 cycle at 2pi (instead of 1 cycle, like a normal cosine).
Then the correct option is:
"On a coordinate plane, a curve crosses the y-axis at (0, 1). It has a minimum of negative 1 and a maximum of 1. It goes through 2 cycles at 2 pi."

A sports shop buys tents for $260 less 25% for buying more than 30 tents. The store operates on a markup of 30% of the sale price and advertises that all items are sold at a discount of 20% of the regular price. What is the regular price of the tents?
Answer: $253.50
Step-by-step explanation:
Markup = 30% of sale price
Store purchase price = (100% - 25%) × 260
Store purchase price = 75% × 260
Store purchase price = 0.75 × 260
Store purchase price = $195
Regular selling price = markup × purchase price
Markup = 30% of purchase price (100+30)%
Regular selling price :
1.30 × $195 = $253.50
You and two friends go to eat pizza there are two deals 10% off of 1 pizza or 30% off of 3 pizzas. Do you want to each pay separately and get 10% off of your bill or do you want to spl it the bill 3 wa
Answer:
Step-by-step explanation:
Assuming the price of 1 pizza is $x. Total number of pizzas is 3.
Considering the first deal,
10% off your pizza is 10/100 × x = 0.1x. The amount that you will pay is x - 0.1x = 0.9x
The cost of the remaining two pizzas is 2 × x = 2x
The total amount to be paid is
2x + 0.9x = $2.9x
Considering the second deal, 30% off the bill would be
30/100 × 3x = 0.9x
The amount to be paid is
3x - 0.9x = $2.1x
Therefore, I prefer the second deal

Which expression represents the volume of a rectangular prism that is not occupied by the cylinder.
Answer:
The volume of the prism not occupied by the cylinder is (150 - 25*pi)*h.
Step-by-step explanation:
In order to calculate the volume of the rectangular prism that is not occupied by the cylinder we need to calculate the total volume of the rectangular prism and subtract it by the volume of the cylinder. We have:
Rectangular prism:
Volume prism = length*height*width
Volume prism = 15*h*10 = 150*h
Cylinder:
Volume cylinder = pi*r²*h = pi*5²*h = 25*pi*h
The volume of the prism that is not occupied by the cylinder is:
volume not occupied = volume prism - volume cylinder
volume not occupied = 150*h - 25*pi*h = (150 - 25*pi)*h
The volume of the prism not occupied by the cylinder is (150 - 25*pi)*h.
