A trapezoid has an area of 20 cm2 and a height z cm. The lengths of the parallel sides are (2z + 3) cm and (6z – 1) cm. Find the height, z, of the trapezoid. In your final answer, include all of the formulas and calculations necessary.
Answers
[tex]\bf A=\cfrac{h(a+b)}{2}\quad \begin{cases} A=20\\ a=6z-1\\ b=2z+3\\ h=z \end{cases}\implies 20=\cfrac{z[(6z-1)~+~(2z+3)]}{2} \\\\\\ 20=\cfrac{z(8z+2)}{2}\implies 20=\cfrac{2z(4z+1)}{2}\implies 20=z(4z+1) \\\\\\ 20=4z^2+z\implies 0=4z^2+z-20[/tex]

since the height is just a length unit, it can't be -2.3646.
Answer:
2.11 cm
Step-by-step explanation:
As you can see in the picture I put the sides in the trapezoid. Now, let's use the area's formula:
A = [tex]\frac{(B+b)*h}{2}[/tex]
where B is the Largest parallel side, b the smallest parallel side and h is the height.
Now,
20 = [tex]\frac{(6z-1+2z+3)*z}{2}[/tex]
20 = [tex]\frac{(8z^{2}+2z}{2}[/tex]
20 = [tex]4z^{2}+z[/tex]
[tex]4z^{2}+z-20=0[/tex]
Then, we use the cuadratic formula z= [tex]\frac{-b+-\sqrt{b^{2}-4ac} }{2a}[/tex] where a=4, b=1 and c=-20.
z= [tex]\frac{-1+-\sqrt{1-4(4)(-20)} }{8}[/tex]
z = [tex]\frac{-1+-\sqrt{1+320} }{8}[/tex]
z = [tex]\frac{-1+-\sqrt{1+320} }{8}[/tex]
z = [tex]\frac{-1+-17.91}{8}[/tex]
As we are searching lenght we choose the positive z value
z = [tex]\frac{-1+17.91}{8}[/tex]
z= [tex]\frac{16.91}{8}[/tex]
z = 2.11 cm.

The 128 employees of a company volunteer 12,480 hours in 26 weeks. On average, how many hours do they all volunteer per weeks? On average, how many hours does each employee volunteer per week?
Answers
The company's employees volunteer an average of 480 hours per week in total, and each employee volunteers an average of 3.75 hours per week.
To calculate the average number of hours the employees of a company volunteer per week, you would divide the total hours volunteered by the number of weeks. So, the calculation for the average weekly volunteer hours for the entire company is 12,480 hours divided by 26 weeks, which is 480 hours per week.
To find out the average number of hours each employee volunteers per week, divide the weekly volunteer hours by the number of employees. Using the previous calculation of 480 hours per week for the entire company and dividing by 128 employees, you get an average of 3.75 hours per employee per week.

Which of the following is not considered one of the four basic types of auto insurance? a. Collision b. Bodily Injury c. Property Damage d. Legal Responsibility
Answers
Answer:
d. Legal Responsibility
Step-by-step explanation:
When purchasing auto insurance, "full coverage" insurance will include:
Collision coverage;
Bodily Injury coverage;
Property damage coverage;
and Comprehensive coverage.
Legal Responsibility is not one of these major types.
Legal Responsibility is not considered as the component of auto insurance because auto insurance only consists of collision, bodily injury, medical payment or personal injury protection and property damage liability. Therefore option (d) is correct.
Further Explanation:
Auto Insurance: It is a contract between two parties of which is the insurer, and the other one is insured. An insurer is a person who agrees to pay the insured in any unforeseen circumstances like accidents, thefts, property damage, etc. In case of auto insurance, the insurance company takes the responsibility of all the damages which are done to the holder of the auto or the auto, but it does not take the responsibility of any legal damage to the insured.

using the Pythagorean theogram find the length of a leg of a right triangle if the other leg is 8 feet long and the hypotenuse is 10 feet long
Answers
The length of a leg of a right triangle is 6 feet.
Used the concept of Pythagoras's theorem states,
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that,
In a triangle, the other leg is 8 feet long and the hypotenuse is 10 feet long.
Let us assume that,
the length of a leg of a right triangle = x
Hence by using Pythagoras's theorem,
10² = 8² + x²
100 = 64 + x²
100 - 64 = x²
36 = x²
x² =36
x = √36
x = 6
Therefore, the length of the leg is 6 feet.

If mountain mack splits his week evenly between carving fishing lures and duck decoys, what is the maximum number of fishing lures and duck decoys he could carve?
From the table it can be seen that in a full week, if mountain mack is carving fishing lures only, he can carve 40 fishing lures. This means that in half of a week, he can carve 20 fishing lures.
Similarly, from the table it can be seen that in a full week, if mountain mack is carving duck decoys only, he can carve 50 duck decoys. This means that in half of a week, he can carve 25 duck decoys.
Therefore, if mountain mack splits his week evenly between carving fishing lures and duck decoys, the maximum number of fishing lures and duck decoys he could carve are 20 fishing lures and 25 duck decoys.
To find the maximum number of fishing lures and duck decoys Mountain Mack can carve, we need to divide his available time equally between the two activities. The maximum number of each item he can carve depends on the total hours available, the time it takes to carve a fishing lure, and the time it takes to carve a duck decoy.
Explanation:To find the maximum number of fishing lures and duck decoys that Mountain Mack could carve, we need to split his week evenly between the two activities. Let's say he has a total of 'x' hours available in a week. Since he'll be dividing his time equally, he'll spend 'x/2' hours carving fishing lures and 'x/2' hours carving duck decoys.
To put this in terms of fishing lures and duck decoys, we need to know the time it takes to carve each item. Let's say it takes 'y' hours to carve a fishing lure and 'z' hours to carve a duck decoy. The maximum number of fishing lures Mountain Mack can carve would be 'x/2y' and the maximum number of duck decoys he can carve would be 'x/2z'.
So, to find the maximum number of fishing lures and duck decoys Mountain Mack can carve, we need to know the total number of hours available in a week ('x'), the time it takes to carve a fishing lure ('y'), and the time it takes to carve a duck decoy ('z').
A trip from new york to seattle is 2852.1 miles. A family wants to make the drive in ten days, driving the same number of miles each day. About how many miles will they drive each day? Round your answer to the nearest tenth of a mile.
Answers
They will drive 285.2 miles every day
Answer:
285.2 miles per day.
Step-by-step explanation:
We have been given that a trip from New York to Seattle is 2852.1 miles. A family wants to make the drive in ten days.
To find the distance traveled by the family each day, we will divide total distance by 10 as:
[tex]\text{Distance traveled by the family each day}=\frac{2852.1\text{ miles}}{\text{ 10 days}}[/tex]
[tex]\text{Distance traveled by the family each day}=\frac{285.21\text{ miles}}{\text{day}}[/tex]
[tex]\text{Distance traveled by the family each day}\approx \frac{285.2\text{ miles}}{\text{day}}[/tex]
Therefore, the family will drive 285.2 miles per day.

How many terms are in the arithmetic sequence 9, 2, −5, . . . , −187?
Answers
[tex]\bf n^{th}\textit{ term of an arithmetic sequence}\\\\ a_n=a_1+(n-1)d\qquad \begin{cases} n=n^{th}\ term\\ a_1=\textit{first term's value}\\ d=\textit{common difference}\\ ----------\\ a_1=9\\ d=-7\\ a_n=-187 \end{cases} \\\\\\ -187=9+(n-1)(-7)\implies -187=9-7n+7 \\\\\\ 7n=9+7+187\implies 7n=203\implies n=\cfrac{203}{7}\implies \boxed{n=29}[/tex]
Final answer:
To find the number of terms in the arithmetic sequence 9, 2, −5, ..., −187, the formula for the nth term of an arithmetic sequence is used with the first term a1, common difference d, and the last term an. By solving an = a1 + (n - 1)*d for n, it is found that there are 29 terms in the sequence.
Explanation:
To determine how many terms are in the arithmetic sequence 9, 2, −5, ..., −187, we use the formula for the nth term of an arithmetic sequence:
an = a1 + (n - 1)*d where,
a1 is the first term,
d is the common difference, and
n is the number of terms.
For the given sequence:
a1 = 9 (the first term)
d = 2 - 9 = -7 (the common difference)
an = −187 (the last term)
We need to find the value of n that satisfies:
−187 = 9 + (n - 1)*(-7)
Solving for n gives us:
−187 - 9 = (n - 1)*(-7)
n - 1 = 28/7
n = 28 + 1
n = 28 + 1
n = 29
Therefore, there are 29 terms in the arithmetic sequence.
Which operation could we perform in order to find the number of milliseconds in a year? 60 * 60 * 24 * 7 * 365 1000 * 60 * 60 * 24 * 365 24 * 60 * 100 * 7 * 52 1000 * 60 * 24 * 7 * 52?
Answers
y = year,
d = day,
h = hour,
min = minute,
s = second,
ms = millisecond.
Then
[tex]1 \, y = (1 \, y)*(365 \, \frac{d}{y} )*(24 \, \frac{h}{d} )*(60 \, \frac{min}{h} )*(60 \, \frac{s}{min} )*(1000 \, \frac{ms}{s} )[/tex]
Therefore, the correct calculation is
1000 * 60 * 60 * 24 * 365
Answer: 1000 * 60 * 60 * 24 * 365
To find the number of milliseconds in a year, multiply the number of milliseconds in a day by the number of days in a year: 86,400 seconds/day * 365 days/year * 1,000 milliseconds/second = 31,536,000,000 milliseconds/year.
Explanation:To find the number of milliseconds in a year, we need to multiply the number of milliseconds in a day by the number of days in a year. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute. So, there are 24 * 60 * 60 = 86,400 seconds in a day. And since there are 365 days in a year, we can calculate the number of milliseconds in a year as:
86,400 seconds/day * 365 days/year * 1,000 milliseconds/second = 31,536,000,000 milliseconds/year
