Answer:
area of trapezoid is [tex]\mathbf{Area=(\frac{4+8}{2})\times 6}[/tex]
Step-by-step explanation:
We have
a = 4 cm
b = 8cm
h = 6cm
We need to find area of trapezoid
The formula used is: [tex]Area=\frac{a+b}{2}\:h[/tex]
Putting values and finding expression:
We will not be solving the expression as question required just to find the expression by putting respective values.
[tex]Area=\frac{a+b}{2}\:h\\Area=(\frac{4+8}{2})\:\times 6[/tex]
So, area of trapezoid is [tex]\mathbf{Area=(\frac{4+8}{2})\times 6}[/tex]

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 160 engines and the mean pressure was 5.3 pounds/square inch (psi). Assume the population standard deviation is 0.6. The engineer designed the valve such that it would produce a mean pressure of 5.4 psi. It is believed that the valve does not perform to the specifications. A level of significance of 0.1 will be used. Find the value of the test statistic. Round your answer to two decimal places.
Answers
Answer:
Test statistic Z = 2.1097
Step-by-step explanation:
Step(i):-
Given that size of the sample 'n' = 160
Given that mean of the Population(μ) = 5.3pounds/square inch
The Standard deviation of the population(σ) = 0.6
Mean of the sample(x⁻) = 5.4
Level of significance =0.1
Step(ii):-
Test statistic
[tex]Z = \frac{x^{-}-mean }{\frac{S.D}{\sqrt{n} } }[/tex]
[tex]Z = \frac{5.4-5.3}{\frac{0.6}{\sqrt{160} } }[/tex]
Z = 2.1097
Final answer:-
Test statistic Z = 2.1097

Solve for y: 3x + 2y = 5y + 9
Answers
Answer:
y = x - 3
Step-by-step explanation:
First you want to combine like terms (so get x on one side and y on the other).
2y = 5y + 9 - 3x
-3y = -3x + 9
Then just solve for y by dividing by -3
y = (-3x + 9)/-3
y = x - 3
Martin has read 40% of a book. He has 30 more pages to finish. How many pages are there in the book?
Answers
Answer:
75
Step-by-step explanation:
Answer:
There are 50 pages in the book.
Step-by-step explanation:
Given that:
Martin has read 40% of the book.
Remaining percent = (100 - 40)% = 60%
Number of pages left to finish = 30
Let,
x be the total number of pages in the book.
60% of x = 30
[tex]\frac{60}{100}x=30[/tex]
0.6x = 30
Dividing both sides by 0.6
[tex]\frac{0.6x}{0.6}=\frac{30}{0.6}\\x= 50[/tex]
Hence,
There are 50 pages in the book.

Graph? Which is linear
Answers
Answer:
Below
Step-by-step explanation:
1. Linear because it is of the form y = mx + b. The variable x is of the first degree.
The coefficient of x (1/3) ( = slope) is positive so it is increasing.
2. This is non-linear because the variable x is an exponent.
3. Because its of the second degree (x^2) - it is non-linear.
Mrs. Bush has a carpet remnant left from putting carpet down in her living room.
The carpet remnant was 4 1/8 square units. If the remnant was 3/4 units wide,
what was the length? *
Answers
Answer: The length = [tex]5\dfrac12[/tex] units
Step-by-step explanation:
Given: Area of carpet = [tex]4\dfarc18 \text{ sq. units}=\dfrac{33}{8}\text{ sq. units}[/tex]
Width of carpet = [tex]\dfrac34[/tex] units
Shape of carpet = Rectangle
Area of rectangle = length x width
So,
length = [tex]\dfrac{Area}{width}[/tex]
[tex]=\dfrac{\dfrac{33}{8}}{\dfrac34}\\\\=\dfrac{33}{8}\times\dfrac43\\\\=\dfrac{11}{2}\\\\=5\dfrac12\text{ units}[/tex]
Hence, the length = [tex]5\dfrac12[/tex] units

2. Angela deposited $600 into an account paying a simple interest rate of 3.6% for 4.5 years. How
much interest did she earn? What was the balance of her account after the 4.5 years (assuming she made no deposits of withdrawals during the time)
Answers
Answer:
Step-by-step explanation:
to find out how much Angela she would have in the bank,
(600*3.6*1)100=21.60 she gains in one year
6 months 21.60/2=10.80
in 4.5 years
(21.60*4)+10.80=86.40+10.80=97.20 interest
the balance=600+97.20=697.20
Part 1. How did you compute sums of dollar amounts that were not whole numbers? For example, how did you compute the sum of $5.89 and $1.45? Use this example to explain your strategy.
Part 2. How did you compute products of dollar amounts that were not whole numbers? For example, how did you compute the cost of 4 pounds of beef at $5.89 per pound? Use this example to explain your strategy.
Answers
Answer:
The answer is below
Step-by-step explanation:
1) When you are computing the sums of numbers, you do not round up. You have to be exact.
Summing numbers involves you adding the numbers together as well as their decimals. Therefore:
$5.89 + $1.45 = $7.34
2) When you are computing the product of numbers, you do not round up. You have to be exact.
The product of numbers involves you multiplying the numbers together. Therefore:
$5.89 per pound * 4 pounds of beef = $23.56

6) A sample of water is being cooled according to the formula is given by
C(t)= 80 – 2t, where t represents the number of minutes the water is cooled,
and C measures the corresponding temperature in degrees Centigrade. The
cooling period ends when the water freezes (0°). Determine the relevant
domain and range for this function.
Determine the relevant Domain and relevant Range for this function. Use
interval notation.
Answers
Answer:
Relevant domain: [0 40]
Relevant range: [0 80]
Step-by-step explanation:
We have the following function:
[tex]C(t) = 80 - 2t[/tex]
In which C(t) is the water temperature.
t is the time.
The colling period ends when the water freezes (0°).
So it freezes after t minutes, and t is found when C(t) = 0. So
[tex]C(t) = 80 - 2t[/tex]
[tex]80 - 2t = 0[/tex]
[tex]2t = 80[/tex]
[tex]t = \frac{80}{2}[/tex]
[tex]t = 40[/tex]
Relevant domain:
Input value of the function, which is in minutes. So between 0(initial) and 40(when the water freezes).
Relevant range:
Initial temperature, which is C(0) = 80, until it freezes, 0. So from 0 to 80.

Imagine that you have the opportunity to purchase a large piece of land for $100,000, after taking out a loan. You have decided to take out a loan for $135,000 in order to cover the cost of the land purchase and building your park. You have hired a financial adviser to help you explore different loan options and decide which one is best for you. Below you will see the different loan options. You will need to calculate the total cost of each loan with interest. Once you have do this you and your group members will need to decide which of the loan options is best for you and why.
Option #1 – charges 5% simple interest per year; this is a short-term loan for only 5-years.
Option #2 – charges 7% simple interest per year; this is a short-term loan for only 3-years.
Option #3 – charges 3.2% simple interest per year; there is no time limit on this loan (as a group determine how long you think it will take you to make enough money to be able to pay back the loan with interest)
Option #4 - charges 10% simple interest per year; only lasts 10 months
Option #5 - charges 12% simple interest per year; only lasts 6 months
