Step-by-step explanation:
(a) Filling in the given information will result in two equations in the two unknowns. Dividing one by the other will tell you the value of b.
n=2
1.8 = A₀·b²
n=3
2.4 = A₀·b³
Dividing the second equation by the first gives ...
2.4/1.8 = (A₀·b³)/(A₀·b²) = b
4/3 = b
__
(b) Substituting this into the first equation, we can find A₀.
1.8 = A₀·(4/3)²
1.8(9/16) = A₀ = 1.0125
A₀ is the value of A when n=0. It is the area of the patch at the beginning of observation, before any days passed.
__
(c) The area will be 7 cm when ...
1.0125·(4/3)^n = 7
(4/3)^n = 7/1.0125 . . . . . . . . . . . . divide by A₀
n·log(4/3) = log(7/1.0125) . . . . . . take logarithms
n = log(7/1.0125)/log(4/3) ≈ 6.72092
It will take about 7 days for the area of the patch to exceed 7 cm.

Step-by-step explanation:
The 5th graders want to raise money for their overnight camping trip by selling cornbread during the school Chili Cook-Off contest. All the pans of cornbread are square. A pan of cornbread costs $12. The customers can buy any fractional part of a pan of cornbread and pay that fraction of $12. For example, ½ of a full pan costs ½ of $12.
Answer:
1 / 12 ; $1
Step-by-step explanation:
Pan was 1/4 full and she buys 1/3 of the cornbread in the pan
The fraction of cornbread she buys is :
1/3 of 1/4
1/3 * 1/4 = 1/12
Hence, she bought 1/12 of cornbread
The amount she pays :
Cost of 1 pan = $12
Therefore, the cost of 1/12 of a pan will be :
1/12 * $12 = $1
Hence, she'll pay $1
Lana bought a sports car for $75,700. If the value of her car decreases 4.3% annually.
When using the exponential DECAY formula, what would be the value of r?
Given:
The initial value of the car = $75,700
Decreasing rate = 4.3%
To find:
The value of r in the exponential DECAY formula.
Solution:
The exponential decay formula is:
[tex]y=a(1-r)^t[/tex]
Where, a is the initial value, r is the rate of decay on decimal and t is the time period.
The initial value of the car is $75,700 and its value decreases 4.3% annually. So,
[tex]a=75,700[/tex]
[tex]r=\dfrac{4.3}{100}[/tex]
[tex]r=0.043[/tex]
The required exponential decay formula is:
[tex]y=75,700(1-0.043)^t[/tex]
Therefore, the value of r in the exponential decay formula is 0.043.

9/2 as a fraction and what is 2/3 reciprocal
Answer:
9/2 = 4 1/2 , 2/3 = 3/2
Step-by-step explanation:
The reciprocal of a fraction is switching the numerator and the denominator.
2/3, switched is 3/2.
To find the mixed form of an improper fraction, you divide the numerator by the denominator.
Like this, 9/2 = 4.5
4 is the whole.
So, 4 would be the whole number.
Then there is 1 left over.
You keep the denominator.
So it would be 4 1/2.

Ralph has a cylindrical container of parmesan cheese. The diameter of the base of the container is 2.75 inches, and the height is 6 inches. What is the area of a horizontal cross section of the cylinder to the nearest tenth of a square inch?
Answer:
The solution is given below:
Step-by-step explanation:
The computation of the area of the horizontal cross section of the cyclinder is given below:
In the case when it is a circle
The area of the circle is
= πr^2
= 3.14 × (2.75 ÷ 2)^2
= 11.873 inches^2
In the case when it is a rectangle
The area of the rectangle is
= 6 × 2.75
= 16.5 inches^2
Hence, the above show the calculations
The area of the horizontal cross section.
When circular is [tex]11.873 inches^2[/tex]
When it is rectangular [tex]16.5inches^2[/tex]
The computation of the area of the horizontal cross section of the cylinder
What is the formula of the area of the circle?The area of the circle is[tex]=\pi r^{2}[/tex]
use the given value in above formula we get,
[tex]= 3.14 \times (\frac{2.75}{2} )^2[/tex]
[tex]= 11.873 inches^2[/tex]
when it is a rectangle then the area of the rectangle is
[tex]= 6 \times 2.75[/tex]
[tex]= 16.5 inches^2[/tex]
Therefore,the area of the horizontal cross section.
when circular is [tex]11.873 inches^2[/tex]
When it is rectangular [tex]16.5inches^2[/tex]

Brenda took a math quiz last week. She got 21 problems correct and 4 problems incorrect. What percentage did Brenda get correct?
Answer:
84%
Step-by-step explanation:
Add the total number of questions (21+4 = 25)
divide 25 by 21
25/21 = 0.84
Multiply 0.84 by 100 to change it to a fraction
0.84*100 = 84%
The percentage that Brenda got correct was 84 percent
Find the missing length of the triangle
20 cm
12 cm
The shape on the left is a square with side length of 12 cm
This means the height of the triangle is 12cm.
Knowing the height and the hypotenuse using the Pythagorean you can solve for the base.
20^2 = 12^2 + x^2
400 = 144 + x^2
Subtract 144 from both sides:
256 = x^2
Take the square root of both sides
X = sqrt(256)
X = 16
X = 16
