Sierra has enough fencing to make three chicken coops shown each has the same perimeter which has the greatest area?
Answer:
Top left triangle has the greatest area
Step-by-step explanation:
Area of a triangle:
area = base × height / 2
a = bh/2
Top Left Triangle:
a = 6 × 5.2 / 2
a = 31.2 / 2
a = 15.6
Top Right Triangle:
a = 8 × 2.9 / 2
a = 23.2 / 2
a = 11.6
Bottom Left Triangle:
a = 2 × 7.9 / 2
a = 15.8 / 2
a = 7.9
Compare areas:
15.6 > 11.6 > 7.9

Joaquin walked exactly 3 _ 4 of a mile. According to the line plot, what is the difference between the distance Joaquin walked and the least distance any of the other students walked to school?
Answer:
The difference is [tex]\frac{3}{8}[/tex] mile
Step-by-step explanation:
The question is incomplete, as the line plot is not attached.
I will answer this question with the attached line plot.
From the question:
[tex]Joaquin = \frac{3}{4}[/tex]
From the attached line plot:
[tex]Least = \frac{3}{8}[/tex]
The difference (D) is:
[tex]D = Joaquin - Least[/tex]
[tex]D = \frac{3}{4} - \frac{3}{8}[/tex]
Take LCM
[tex]D = \frac{6 - 3}{8}[/tex]
[tex]D = \frac{3}{8}[/tex]
Hence: The difference is [tex]\frac{3}{8}[/tex] mile

Answer: )D
Step-by-step explanation:
A geometric sequence is given by the recursive rule $a_1=\frac{2}{3},\ a_n=3a_{n-1}$ . Give an explicit rule for the nth term of the sequence $b_1,\ b_2,\ b_3,\ \dots\ ,$ given that $b_1=a_1,\ b_2=a_3,\ b_3=a_5,\ \dots$ .
Answer:
[tex]b_n = \frac{2}{27} (9^n)[/tex]
Step-by-step explanation:
Given
[tex]a_1=\frac{2}{3},\ a_n=3a_{n-1}.[/tex]
Required
An explicit rule for [tex]b_1,\ b_2,\ b_3,\ \dots[/tex]
Where [tex]b_1=a_1,\ b_2=a_3,\ b_3=a_5,\ \dots[/tex]
We have:
[tex]a_1=\frac{2}{3},\ a_n=3a_{n-1}.[/tex]
Calculate a2
[tex]a_2 = 3a_{2-1}[/tex]
[tex]a_2 = 3a_1[/tex]
[tex]a_2 = 3 * \frac{2}{3}[/tex]
[tex]a_2 = 2[/tex]
Calculate a3
[tex]a_3 = 3a_{3-1}[/tex]
[tex]a_3 = 3a_2[/tex]
[tex]a_3 = 3 *2[/tex]
[tex]a_3 = 6[/tex]
Calculate a4
[tex]a_4 = 3a_{4-1}[/tex]
[tex]a_4 = 3a_3[/tex]
[tex]a_4 = 3*6[/tex]
[tex]a_4 = 18[/tex]
Calculate a5
[tex]a_5 = 3a_{5-1}[/tex]
[tex]a_5 = 3a_4[/tex]
[tex]a_5 = 3*18[/tex]
[tex]a_5 = 54[/tex]
So:
[tex]b_1=a_1,\ b_2=a_3,\ b_3=a_5,\ \dots[/tex]
[tex]a_1=\frac{2}{3}[/tex] [tex]a_3 = 6[/tex] [tex]a_5 = 54[/tex]
The above sequence form a geometric sequence.
Calculate common ratio (r)
[tex]r = \frac{b_3}{b_2}[/tex]
[tex]r = \frac{a_5}{a_3}[/tex]
[tex]r = \frac{54}{6}[/tex]
[tex]r = 9[/tex]
So, the explicit formula is:
[tex]b_n = b_1 * r^{n-1[/tex]
[tex]b_1=a_1[/tex], so:
[tex]b_n = a_1 * r^{n-1[/tex]
[tex]a_1=\frac{2}{3}[/tex], so:
[tex]b_n = \frac{2}{3} * 9^{n-1[/tex]
Split:
[tex]b_n = \frac{2}{3} * \frac{9^n}{9}[/tex]
[tex]b_n = \frac{2}{3*9} (9^n)[/tex]
[tex]b_n = \frac{2}{27} (9^n)[/tex]
The explicit rule is: [tex]b_n = \frac{2}{27} (9^n)[/tex]

Answer:
∠b = 64°
Step-by-step explanation:
We know that a complete rotation is 360°, so:
∠b + 57° + 239° = 360°
∠b = 360° - 57° - 239°
∠b = 64°
Given the following exponential function, identify whether the change represents
growth or decay, and determine the percentage rate of increase or decrease.
y = 70(0.96)
Answer:
it is a decay, it's value drops by 4%
Step-by-step explanation:
0.96 is less than 1 so it is a decay function.
1-0.96 = 0.04 so it drops at the rate of 4%

How can you tell if a pattern is quadratic or linear?
Answer: By finding the differences between the y-values, we can determine the degree of the model for the data.
If the first difference is the same value, the model will be linear.
If the second difference is the same value, the model will be quadratic.

Which of the following equations has infinitely many real solutions?
A. 2(x - 7) = 2x + 14
B. 2(x - 7) = 2x – 14
C. 2x + 1 = 2x - 1
D. 2x + 1 = x - 1
Answer:
B - 2(x -7) = 2x - 14
Step-by-step explanation:
If you expand this equation, you get 2x-14 = 2x-14. This means that the equation will be true for any x, and has infinitely many solutions

The largest three-digit multiple of 6 ?
Answer:
Step-by-step explanation:
100 is the smallest three-digit number. 999 is the highest three-digit number. 102 is the smallest three-digit number divisible by six. 996 is the largest three-digit number divisible by six.
Answer:
744Step-by-step explanation:
The largest 3-digit multiple of 6 that uses digits 4 and 4.
The multiple of 6 is an even number which is divisible by 3.
Numbers are only divisible by 3 if the sum of the digits is divisible by 3.
We have 4 + 4 = 8 and the largest digit to add is 7.
744 is the largest possible number.Proof:

What is a Two-way Table?A two-way table can be described as a table that displays the frequencies of two categorical variables, in such a way that, one category is represented by columns and the other by rows.
Given the information, the missing values in the two-way table would be:
Total number of boys enrolled = 150
Boys that enrolled in Algebra 1 = 2(46) = 92
Boys that enrolled in Algebra 2 = 150 - 92 - 46 = 12
Girls that enrolled in Algebra 1 = 150 - 54 - 28 = 68
Total for boys and girls that enrolled in Geometry = 46 + 54 = 100.
Therefore, the missing values in the two-way table is shown in the table in the image attached below.

Step-by-step explanation:
Mr. Hoosier has gathered all these data about his finances.
Salary $159,000
Taxable interest $5600
Municipal Bond interest $15,000
Total Itemized deductions $9500
The personal exemption is $4700. The standardized deduction for a single filer is 5000.
Answer:
1. His tax is $37,490.
2. His average effective tax rate is 22%
3. His average tax rate is 24.93%
4. His marginal tax rate is 35%.
5. His tax liability will fall by $170
6. His tax liability will fall by $500.
Step-by-step explanation:
Note: This question is not complete. See the attached pdf file for the complete question.
The explanation of the answer is now given as follows:
1. What is his tax?
Note: See the attached excel for Mr. Hoosier's Tax Computation Based on the Tax Table in the question.
From the attached excel file, the Net tax is $37,490 which is his tax.
Therefore, his tax is $37,490.
2. His average effective tax rate
His average effective tax rate = Tax / (Taxable income + Tax exempt income) = Tax / (Taxable income +Municipal Bond interest) = $37,490 / ($150,400 + $20,000) = 0.2200, or 22%
3. His average tax rate
Average tax rate = Tax / Taxable Income = $37,490 / $150,400 = 24.93%
4. His marginal tax rate
His marginal tax rate is 35% as in the tax computation used based on the tax table.
5. Assume he discovers that he is eligible for a 500 tax deduction. How much does his tax liability fall with that addition?
Taxable income = 150400 - 500 = $149,900
Based on the tax table in the question, we have:
Tax = 8850 + (149900 - 55000) * 30% = $37,320
Reduction in tax liability = $37,490 - $37,320 =$170
Therefore, his tax liability will fall by $170
6. Now he discovers that he is eligible for a $500 tax credit. How much does his tax liability fall due to this credit?
The purpose of the tax credit is to make tax liability reduced dollar by dollar.
Therefore, if he discovers that he is eligible for a $500 tax credit, his tax liability will fall by $500.

The amount that each company charges per hour on the pool is known, however the amount of hours they will be working is not, and is needed to distinguish which company is cheaper. Therefore, the number of hours is substitued by x and it is right next to the amount they charge for each hour. To find what each company charges, you must sum up what they charge and what they charge per hour, times the hours they will have to work on it( which is unknown and by x).
