Answer:
9/10 =0.9
Step-by-step explanation:
We have been given to calculate 1 1/2 times 3/5 . First of all ,we shall convert 1 1/2 ( a mixed fraction form) to a proper fraction form .
1 1/2 is actually 1 + 1/2 =3/2
1 1/2 X 3/5 =3/2 X 3/5 =9/10
9/10 is actually 0.9
Therefore we have finally converted this into division sentence too

JUSTIFY REASONING Consider the conjecture if two points are equidistant from a third point, then the three points are collinear is the
conjecture true or false? Justify your argument. If false, give a counterexample.
Select Choice if the two points create a straight angle that includes the third point, then the conjecture is Select ChoiceIf the two
points do not create a straight angle with the third point, then the conjecture is Select Choice
It is a supposition that it is true if two points are equally far apart from a third point and the three points are collinear.
Collinear points are what?If three or more points lie on a single straight line, they are said to be collinear. An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two points determine a line, two points are trivially collinear.
Collinear points are those that are situated along a identical straight line.
The supposition is correct since all three points are located on the same line.
if the two points create a straight angle that includes the third point, then the conjecture is true.
If the two points do not create a straight angle with the third point, then the conjecture is false.

Answer:
24.98 units
Step-by-step explanation:
You want the perimeter of triangle ABC with vertices A(-5, 4), B(1, -2), and C(3,6).
Distance formulaThe distance between two vertices can be found using the formula ...
d = √((x2 -x1)² +(y2 -y1)²)
ApplicationThe distance between A and B is ...
d = √((1 -(-5))² +(-2 -4)²) = √(6² +(-6)²) = 6√2 ≈ 8.485
The attached spreadsheet performs the same calculation on all the pairs of points. (The distance from each point to the one below it is listed.)
PerimeterThe perimeter of the triangle is the sum of the segment lengths. That is also shown in the spreadsheet.
P = AB +BC +CA
P = 8.485 +8.246 +8.246 ≈ 24.98
The perimeter of triangle ABC is about 24.98 units.

A andwich hop erve 4 ounce of meat and 3 ounce of cheee on each andwich. After making andwiche for an hour the hop owner ha ued 91 combined ounce of meat and cheee
How many combined ounce of meat and cheee are ued on each andwich?
The combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.
We have the following information:
A sandwich hop serve 4 ounce of meat and 3 ounce of cheese on each sandwich. After making sandwiches for an hour the hop owner has used 91 combined ounce of meat and cheese.
Now, we know the combined ounces of meat and cheese for 1 sandwich will be given as follows:
Ounces of meat + ounces of cheese
4+3
7 ounces
Now, in an hour 91 ounces of combined cheese and meat are used.
So, we have the following expression:
Number of sandwiches made in 1 hour = Total ounces used/ounces used in 1 sandwich
Number of sandwiches = 91/7
Number of sandwiches = 13
Ounces of meat used in 13 sandwiches = 13*4
Ounces of meat used in 13 sandwiches = 52 ounces
Ounces of cheese used in 13 sandwiches = 13*3
Ounces of cheese used in 13 sandwiches = 39 ounces
Hence, the combined ounces of meat and cheese used on each sandwich is 7 ounces and the combined ounces of meat on all sandwiches is 52 ounces and that of cheese on all sandwiches is 39 ounces.

Nicholas wants to buy a new computer that is on sale for $899. His parents will loan him the money if he repays them. He has $234 in his savings account and plans to work as a camp counselor to earn money during the summer. If he earns $35 per day, how many days will Nicholas have to work in order to fully repay his parents?
Answer: He will work for 19 days.
Step-by-step explanation:
If Nicholas has 234 dollars and the computer he wants to put is 899 dollars, you have to subtract to see how much he has to take the loan from his parents in order to buy the computer.
899 - 234 = 665
He took a loan of 665 dollars from his parents
To figure out how many days he needs to work to pay that amount, you divide the amount he earns each day with the amount of loan he took.
So 665 divided by 35 = 19
He has to work 19 days to pay off the 665 dollar loan he took from his parents.
We can check this answer by multiplying 35 x 19 , which equals to 665.
Hope this helps!

Whenever a probability sample is drawn from a population, it is not enough to simply report the sample's descriptive statistics, for these measures contain a certain degree of error due to the sampling process.
Thus the answer is ‘ true’.
A population is any entire group that has at least one trait in common that is relevant to a given issue or experiment in statistics.
A probability sample is one that is drawn using a method of random selection that is compatible with the known odds for each member of the population to be selected, and that takes these probabilities into account when generating estimates from the sample.
If the chosen sample does not accurately reflect the total population of data, there has been a sampling error, which is a statistical error resulting from sampling.

What is a quadratic polynomial?A quadratic polynomial is a polynomial in which the highest power of the unknown is 2.
What is a perfect square?A perfect square is a number suvh that it is equal to another number multiplied by itself
How to make the quadratic polynomial a perfect square?Since we have the quadratic polynomial x² + 18x, and we wnat to convert it to a perfect square.
To be a perfect square, we want it in the form (x + a)² = x² + 2ax + a² (1)
Compring the quadratic polynomial with equation (1), we have that
2a = 18
a = 18/2
a = 9
⇒ a² = 9² = 81
So, substituting a = 9 into equation (1), we have
(x + a)² = x² + 2ax + a²
(x + 9)² = x² + 2(9)x + 9²
= x² + 18x + 81

An item is regularly priced at $81. Shen bought it on sale for 45% off the regular price
Use the ALEKS calculator to find how much Shen paid.
For this problem there are $44.55 Shen paid.
What is sale price?
The cost following a discount applied to the original cost. This item is being sold for $8.00. We must first calculate the discount amount if the discount is a percentage: • Original price x discount rate equals the discount amount.
Given:
An item is regularly priced at $81.
Shen bought it on sale for 45% off the regular price.
The formula for calculating the sales price of an item is:
s = p - (p x d)
Where:
s is the sales price: what we are calculating in this problem.
p is the regular price of the item: $81 for this problem.
d is the discount rate: 45% for this problem. "Percent" or "%" means "out of 100" or "per 100", Therefore 45% can be written as 45/100.
Substituting and calculating s gives:
[tex]s = 81 - (81 *\frac{45}{100}) \\s = 81 - (36.45)\\s = 44.55[/tex]
s = $44.55
Hence, for this problem there are $44.55 Shen paid.

The equation that has a real zero at x = 2 is y = -[tex]2^x[/tex] + 4.
Option A is the correct answer.
What is an equation?An equation contains one or more terms with variables connected by an equal sign.
Example:
2x + 4y = 9 is an equation.
2x = 8 is an equation.
We have,
The graph shows an x-intercept at x = 2, which means that the function has a real zero at x = 2.
Now,
We can check which of the given equations has this property by plugging in x = 2 and seeing if the corresponding y-value is zero.
For y = [tex]-2^x[/tex] + 4,
y = -2² + 4 = 0
This equation has a real zero at x = 2.
For y = 2^x,
y = 2² = 4,
This equation does not have a real zero at x = 2.
For y = log₂(x + 2) + 1,
y = log₂(2 + 2) + 1 = log₂4 + 1 = 3
This equation does not have a real zero at x = 2.
For y = log₂(-x + 2),
-x + 2 < 0, which means that x > 2.
This equation does not have a real zero at x = 2.
Therefore,
The equation that has a real zero at x = 2 is y = -[tex]2^x[/tex] + 4.
