One aluminum can weights 1/25 pound. If your school starts a recycling drive how many cans will your school need to collect to recycle one ton?
Answers
First you have to find how many cans make a pound
1/25 * 25 = 1
It takes 25 cans to get to 1 pound
There are 2000 pounds in a ton
Multiply the amount of cans to make a pound by the amount of pounds in a ton
25 * 2000 = 50000
The answer is 50,000 aluminum cans

Q10 Q2.) Find the standard form of the equation of the parabola satisfying the given conditions.
Answers
1. You have that the standard form of the equation of the parabola must satisfy the following conditions given in the exercise above:
Focus: (-1,4) and Directrix: y=2
2. Therefore you have:
√(x0-(-1))²+(y0-4)²=|y0-2|
(x0+1)²+(y0-4)²=(y0-2)²
3. When you simplify the expression above and clear y0, you obtain:
y0=y
y=1/4(x²+2x+13)
y=(x²/4)+(x/2)+(13/4)
Therefore, the answer is: y=(x²/4)+(x/2)+(13/4)

5-2i and 7+6i find the midpoint
Answers
So that would be ((5+7) / 2, (-2+6) / 2) = (6, 2)
So then answer would be 6+2i
The midpoint between the complex numbers 5-2i and 7+6i is 6 + 2i.
Explanation:To find the midpoint between two complex numbers, we can use the formula:
Midpoint = (Re(z1) + Re(z2))/2 + (Im(z1) + Im(z2))/2i
Applying the formula to the given complex numbers 5-2i and 7+6i, we have:
Midpoint = (5 + 7)/2 + (-2 + 6)/2i
Midpoint = 12/2 + 4/2i
Midpoint = 6 + 2i

ΔABC and ΔXYZ are similar triangles. If BC = x + 7, AC = x + 6, YZ = 4 − x, and XZ = 3 − x, find the value of x.
Answers
Answer:
-3/2 or -1.5
Step-by-step explanation:
-3/2 = -1.5
BC = -1.5 + 7 = 5.5
AC = -1.5 + 6 = 4.5
YZ = 4 - (-1.5) = 5.5
XZ = 3 - (-1.5) = 4.5
a band that will be the opening act for a concert charges a $700.00 flat fee as well as 16% of all ticket profits from ticket sales. if the band earned $1,200, how much was made in total ticket sales for the show?
Answers
1. Subtract the flat fee 1,200-700 =500
2. 500 is what just the band made. Divide that by .16 (16%) to get the total ticket amount... 500 divided by .16 = 3,125

The current size of an image on Samuel's computer is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 8 inches and the width is labeled as width equal to 10 inches. What are the dimensions of the image at fraction 1 over 2 times its current size
Answers
You can just divide each by 2.
Answer:
The length and the width of image is 4 inches and 5 inches respectively
Step-by-step explanation:
Given : Length of rectangle is 8 inches
Width of rectangle is 10 inches
To Find: What are the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
Solution:
Length of rectangle is 8 inches
Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
So, Length of image = [tex]\frac{1}{2} \times 8 = 4[/tex]
Thus the length of image is 4 inches.
Width of rectangle is 10 inches
Since we are given that the dimensions of the image at fraction [tex]\frac{1}{2}[/tex] times its current size
So, width of image = [tex]\frac{1}{2} \times 10 = 5[/tex]
Thus the width of image is 5 inches.
Hence the length and the width of image is 4 inches and 5 inches respectively.

A video posted on the internet is becoming very popular,and the total number of views is increasing by 40% every hour if the video currently has 38,000 views how many views will it have in 2 hours
Answers
Final answer:
The video with an initial 38,000 views will have approximately 74,480 views in 2 hours when it is increasing by 40% every hour.
Explanation:
To calculate the number of views a video will have in 2 hours if it is increasing by 40% every hour, we will use the formula for percentage growth. Initially, the video has 38,000 views. After one hour, the views will be increased by 40%, and after two hours, this new amount will again be increased by 40%. The formula for calculating the number of views after each hour is:
Views after n hours = Initial views × [tex](1 + growth rate)^n[/tex]
Where:
Initial views = 38,000
Growth rate = 40% = 0.40 (as a decimal)
n = number of hours
After 1 hour:
Views after 1 hour = 38,000 × (1 + 0.40)^1
Views after 1 hour = 38,000 × 1.40 = 53,200
After the second hour, we will use the number of views from the first hour to calculate the increase:
Views after 2 hours = 53,200 × [tex](1 + 0.40)^1[/tex]
Views after 2 hours = 53,200 × 1.40 = 74,480
Therefore, the video will have approximately 74,480 views in 2 hours.

in the triangle ABC
180=∡A+∡B+∡C
∡A=180-(90+55.15)-----> ∡A=34.85°
tan A=BD/y-------> y=BD/tan A-----> y=11.49/tan 34.85----> y=16.50 ft
the answer is
y=16.50 ft
1. First, you must apply the Pythagorean Theorem to calculate the heigth of the triangle, as below:
a^2=b^2+c^2
b=√(a^2-c^2)
b=√(14)^2-(8)^2
b=√132
b=11.48
2. Now, you must calculate the angle ∠BC, as below:
Sin(α)^-1=opposite/hypotenuse
Sin(BC)^-1=8/14
∠BC=34.84°
3. Therefore, the angle ∠BA is:
∠BA=90°-34.84°
∠BA=55.15°
4. Then, you have:
Tan(55.15°)=y/11.48
y=16.48

y = -6cos4x
The function is defined for all values of x, therefore, the domain is:

For x = 0
y = -6cos (4 (0))
y = -6cos (0)
y = -6 (1)
y = -6
For x = pi / 4
y = -6cos (4 (pi / 4))
y = -6cos (pi)
y = -6 (-1)
y = 6

Answers
answer
D. 1/5
Answer:
Option D. [tex]\frac{1}{5}[/tex] is the correct option.
Step-by-step explanation:
Total number of solution sets n(S) (sample space) = 5×5 = 25
(Since a ping-pong ball can land on any block of the toss board so total number of events which can occur will be = 25)
Now preferred events n(E) = 5
(Since number of grey squares where ping-pong ball can land are = 5)
Therefore probability of landing of ping pong ball on a grey square P(E) = [tex]\frac{n(E)}{n(S)}[/tex]
P(E) = [tex]\frac{5}{25}[/tex]
P(E) = [tex]\frac{1}{5}[/tex]
Therefore, Option D. [tex]\frac{1}{5}[/tex] will be the answer.

Suppose that the demand equation for a certain item is 1p+1x2−160=0. evaluate the elasticity at 65:
Answers
Here, the question has omitted to define variables, so we will ASSUME
p=price
x=variable,
and we're given
p+x^2-160=0
We calculate
[tex]\delta{x}/\delta{p}[/tex] by implicit differentiation with respect to p:
1+2x (dx/dp)=0
=>
E(x)=(dx/dp)=-1/(2x)
Therefore the price elasticity at x=65 is
E(65)=1/(2*65) =-1/130 (approximately -0.00769)
The required value of elasticity at x = 65 is -0.007.
Given that,
The demand equation for a certain item is [tex]1p + 1x^{2} -160 = 0[/tex].
We have to determine,
The value of elasticity at 65.
According to the question,
The price elasticity of demand is calculated as the percentage change in quantity divided by the percentage change in price.
Therefore,
Price of elasticity = [tex]\frac{dp}{dx}[/tex]
Calculate change by differentiation with respect to p:
[tex]\dfrac{d(p+x^{2} -160)}{dx}\\\\1 + 2x\frac{dp}{dx} = 0\\[/tex]
Then,
[tex]E(x) = \frac{dp}{dx} = \frac{-1}{2x}[/tex]
Therefore, The elasticity at x = 65 is ,
[tex]E(65) = \frac{-1}{2(65)} = -0.007[/tex]
Hence, The required value of elasticity at x = 65 is -0.007.
