Answer:
To find out which one is the better buy we have to find out what the unit price of each one is. To find a unit price you divide the ounce by the cost.
Step-by-step explanation:
5/90=18 cents
12/240=5 cents
the 12 ounce can is less per ounce so the 12 ounce can is the better buy.
Perimeter of a rectangle is 72 inches. The width is twice
the lenth. What is the width and length?
Answer:
24″ width, 12″ length. Let the length be X inches, then width is 2X inches, giving perimeter 2(X+2X)=6X inches, which is 72″. hence X, length =12″, and width 24″. The perimeter of a rectangle is 64 m.
Step-by-step explanation:
There ya go,
Answer:
36
Step-by-step explanation:
72 divided by four because its perimeter and you get 18 on each side since the width is double then you would do 18x2 and get 36.

Answer:
h = -2
Step-by-step explanation:
Just plug it into a calculator
Answer:
h=-2
Step-by-step explanation:
1/3h = -2/3
To find the h divide both sides by 1/3.
1/3h÷1/3 = -2/3÷1/3
h=-2
Answer the following questions based on the graphic given below.
The person casts a shadow ___ feet long.
The building casts a shadow ___ feet long.
The ratio of the person’s shadow to the building’s shadow is ___ to ___.
If the other side of the building is 10 feet tall, the person will be ___ feet tall.
Answer:
The person casts a shadow 3 feet long.
The building casts a shadow 15 feet long.
The ratio of the person’s shadow to the building’s shadow is 1 to 5.
If the other side of the building is 10 feet tall, the person will be 2 feet tall.
(I'm not sure what the last question meant by "the other side of the building". I assume it means the height of the building? 2 feet tall seems a bit short for a person though, but that would be correct since the building's height is 2/3 of the shadow's length, and 2/3 of the person's shadow length, 3, is 2 feet)
The building, the person and their shadows form a right triangle; The texts that complete the blanks are 3 feet long, 15 feet long, 1 to 5 and 2 feet tall.
What is a right triangle?A right triangle is a triangle that has an angle of 90 degrees
From the question, we have the following highlights:
Person's shadow = 3 feetBuilding's shadow = 15 feetSo, the ratio of the person’s shadow to the building’s shadow is
Ratio = 3 feet : 15 feet
Simplify
Ratio = 1 : 5
When the building's height is 10 feet, we have:
Person : 10 feet = 1 : 5
Multiply by 2 feet
Person : 10 feet = 2 feet : 10 feet
By comparison, we have:
Person = 2 feet
Hence, if the other side of the building is 10 feet tall, the person will be 2 feet tall.

What is the hardest subject in Middle School?
Answer:
in my middle school it was history
Step-by-step explanation:
Asa's most recent credit card statement had a balance of $2,622.77. The minimum payment warning box indicates that it will take 12 years to pay off the card if
be makes the minimum payment of $28 per month. If he makes a monthly payment of $100, it will take 3 years to pay off the balance. What will be the percent
increase in total payments if Asa only pays the minimum rather than the $100 per month?
Answer:
12%
Step-by-step explanation:
In order to calculate this we first need to find the total that she would pay if she were to choose either of these options. We do this by multiplying the number of years it would take to pay off the loan by the 12 months in a year, and then we multiply this product by the monthly payment like so...
Minimum Payment:
(12 * 12) * 28 = $4,032
$100 a month payment:
(12* 3) * 100 = $3,600
Now that we have both we need to divide the minimum payment total by the $100 a month payment total to get the percentage increase in decimal form
$4,032 / $3,600 = 1.12
Now we subtract 1 and multiply by 100 to turn this decimal into a percentage
(1.12 - 1) * 100 = 12%
Finally, we can see that if Asa only pays the minimum then she would be paying a 12% increase as opposed to paying the $100 a month

5. Past experience shows that the standard deviation of the distances traveled by consumers to patronize Chinese restaurants is 2 km. How large a sample is needed to estimate the population mean distance traveled to within 0.4 km
Answer:
96
Step-by-step explanation:
Given that :
Standard deviation (s) = 2km
Error in estimation is within 0.4 km ; Error (E) = 0.4 km
Using the relation :
Sample size = ((Zα/2 * s) /E)^2
Using α = 0.05
The Zcritical at 0.05 = Z0.025 = 1.96
Sample size = ((1.96 * 2) / 0.4)^2
Sample size = (3.92 / 0.4)^2
Sample size = 9.8²
Sample size = 96.04
Required sample size = 96

A spherical balloon is being inflated with helium at a rate of 20π cm3/min. How fast is the balloon's radius changing when the radius is 1 cm?
Answer:
5 cm/min
Step-by-step explanation:
A spherical balloon is being inflated with helium at a rate of 20π cm³/min.
The volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3[/tex] ...(1)
Differentiate equation (1) wrt t as follows :
[tex]\dfrac{dV}{dt}=3\times \dfrac{4}{3}\pi r^2\times \dfrac{dr}{dt}\\\\\dfrac{dV}{dt}=4\pi r^2\dfrac{dr}{dt}\ ....(1)[/tex]
Put dV/dt = 20π cm³/min and r = 1 cm, we can fin dr/dt
[tex]\dfrac{dV}{dt}=4\pi r^2\dfrac{dr}{dt}\\\\20\pi =4\pi (1)\times \dfrac{dr}{dt}\\\\\dfrac{dr}{dt}=5\ cm/min[/tex]
So, the radius of changing at the rate of 5 cm/min.
Using implicit differentiation, it is found that the radius is changing at a rate of 5 cm/min.
The volume of a sphere of radius r is given by:
[tex]V = \frac{4\pi r^3}{3}[/tex]
Applying implicit differentiation, the rate of change is of:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
A spherical balloon is being inflated with helium at a rate of 20π cm3/min, hence [tex]\frac{dV}{dt} = 20\pi[/tex]The radius is of 1 cm, hence [tex]r = 1[/tex].Then:
[tex]\frac{dV}{dt} = 4\pi r^2\frac{dr}{dt}[/tex]
[tex]20\pi = 4\pi (1)^2\frac{dr}{dt}[/tex]
[tex]\frac{dr}{dt} = \frac{20}{4}[/tex]
[tex]\frac{dr}{dt} = 5[/tex]
The radius is changing at a rate of 5 cm/min.

What is a complex number?It is defined as the number which can be written as x+iy where x is the real number or real part of the complex number and y is the imaginary part of the complex number and i is the iota which is nothing but a square root of -1.
The complete question is:
Which graph represents 2(cos(2π/3)+i sin(2π/3))?
The graphs are in the picture, please refer to the picture.
We have a complex number;
= 2(cos(2π/3)+i sin(2π/3))
= 2(cos120 + i sin120)
= 2(-0.5 + i 0.866)
= -1 + i 1.732
The point is (-1, 1.732)
Thus, the graph second representing the complex number 2(cos(2π/3)+i sin(2π/3)) on a coordinate plane option second is correct.
