108x25^2divided by
2^6 x 5^2
Answer:
108 x 25² divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]
Step-by-step explanation:
Given;
108 x 25² divided by 2⁶ x 5²
The expression is simplified as follows;
[tex]\frac{108\times 25^2}{2^6 \times 5^2} = \frac{108\times 625}{64\times25} =\frac{675}{16} = 42\frac{3}{16}[/tex]
Therefore, 108 x 25² divided by 2⁶ x 5² is equal to [tex]42\frac{3}{16}[/tex]

A restaurant offers a catering service which costs $25.00 per person with a $119.50 service charge. For parties of 50 or more people, a group discount applies, and the cost is $20.00 per person along with the service charge dropping to $59.00. (a) Write a piecewise-defined linear function which calculates the total cost T of the catering service which serves n people.
Answer:
T1(n) = 25n +119.50 where n belongs to [tex]1 \leq n <50[/tex].
T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].
Step-by-step explanation:
We are given two situations first is for normal days and the other is for days when 50 or more people are going to this restaurant for the party.
Let the number of person going for this restaurant be "n"
For normal day, we are given
catering service = $25 per person
service charge = $119.50
Let the total cost of the restaurant be T
Cost for this case will be T1
T1(n) = 25n +119.50 where n belongs to [tex]1 \leq n <50[/tex]
similarly for the case when 50 or more than that goes to this restaurant for party.
cost after discount
Catering service = $20.00 per person
service charge = $59.00
now the cost of this case will be T2
T2(n) = 20n + 59 where n belongs to [tex]50\leq n[/tex].
Therefore the two piecewise linear functions represents the total cost of the restaurant for serving n people.
Is 4/10 equal to 2/3
Answer:
no, its not
Step-by-step explanation:
you can find the decimals by dividing the numerator and the denominator
4/10 = 0.4
2/3 = 0.6666666......
so the values are obviously different

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.
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.

The area of the given triangle is (√3/6) s² so option (C) will be correct.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.
Area of right angle triangle ;
A = (1/2) × Base × Hight
Tan 30° = height/s
1/√3 = height/s
height = s/√3
Now,
A = (1/2) × s × s/√3
A = 1/(2√3) × s²
Multiply √3 on numerator and denominator
A = √3/6 × s²
Hence "The area of the given triangle is (√3/6) s²".

Charlin got 20 questions correct on her exam and scored a 80%. How many (total) questions were on the exam
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.
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

The ratio of girls to boys in a classroom is 3.1. How many boys are there in the classroom if
it has 12 girlS
Answer: 4
Step-by-step explanation:
To find out how many boys are in the classroom you must divide 12 from 3 to find the rate of change. 12/3= 4 so then you multiply 1*4 to find out how many boys are in the classroom. 1*4=4

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.
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
