The correct options are B. An angle that measures 65 is an acute angle. and C. An acute angle measures less than 90 degrees.
To determine the truth of each statement, let's analyze each option:
A. An angle that measures 180 degrees is a reflex angle.
This statement is false. An angle that measures exactly 180 degrees is a straight angle, not a reflex angle. A reflex angle is greater than 180 degrees but less than 360 degrees.
B. An angle that measures 65 degrees is an acute angle.
This statement is true. An acute angle is an angle that measures less than 90 degrees. Since 65 degrees is less than 90 degrees, it is indeed an acute angle.
C. An acute angle measures less than 90 degrees.
This statement is true. By definition, an acute angle is any angle whose measure is less than 90 degrees.
D. An angle that measures 300 degrees is an obtuse angle.
This statement is false. An obtuse angle is an angle that measures more than 90 degrees but less than 180 degrees. Since 300 degrees is greater than 180 degrees, it is not an obtuse angle but rather a reflex angle.

Write an expression to find the difference in the maximum area and minimum area of a nys high school soccer field. Then evaluate the expression.
Max length 100yards
Max length 120 yards
Minimum width 55 yards
Maximum width 80 yards
The difference between the maximum and minimum area of the soccer field is found by calculating the maximum and minimum area using the given dimensions, and then subtracting the minimum area from the maximum area. Result is 4100 square yards.
Explanation:First, the area of a rectangle (like a soccer field) can be found with the formula Area = Length x Width. To find the difference between the maximum area and the minimum area of the field, we'll need to do two calculations.
For the maximum area, we'll use the maximum length of 120 yards and the maximum width of 80 yards: Max Area = 120 yards x 80 yards = 9600 square yards.
For the minimum area, we'll use the minimum length of 100 yards and the minimum width of 55 yards: Min Area = 100 yards x 55 yards = 5500 square yards.
Now you subtract the minimum area from the maximum area: 9600 square yards - 5500 square yards = 4100 square yards. This is the difference in area between the smallest and largest possible soccer fields.

Answer:
All multiples of 48 between 480 and 1200, inclusive
Step-by-step explanation:
I took the test;)
The practical range of the function is [480, 1200].
Explanation:The function f(t)=48t represents the amount of money earned by Clarence for selling t subscriptions each week. To find the practical range of the function, we need to determine the minimum and maximum value of t that satisfy the given conditions. Since Clarence sells at least 10 and no more than 25 subscriptions each week, the practical range of the function is [480, 1200]. This means that the amount of money earned by Clarence each week can range from $480 to $1200.

Suppose you have already been waiting for one hour for a taxi. what is the probability that one arrives within the next 10 minutes?
The probability of one arrives within the next 10 minutes when he already been waiting for one jour for a taxi is,
P (X > 70 | X > 60) = P (X > 10) = 1 – P (X ≤ 10) = 1 – {1 – e ^ -((1 / 10) 10)} = e ^ -1
= 0.3679
The probability of one arrives within the next 10 minutes when he already been waiting for one hour for a taxi is 0.3679
Felicia installed a new pool for $17,190 using a 12-month deferred payment plan with an interest rate of 18.67%. What is the balance after the deferment period if payments of $589 are made each month?
a. $10,122.00
b. $20,688.76
c. $13,620.76
d. $17,190.00
Answer:
a. $10,122.00
Step-by-step explanation:
By definition the deferment period is a time during which a borrower does not have to pay interest or repay the principal on a loan.
In this case the balance should be the initial value $17,190, but Felicia made 12 payments of $589 each one.
So, $589 x 12 = $ 7,068.
$17,190- $ 7,068 = $10,122
Sanjay rides his bike to work 15 kilometers in two days. He works five days per week. How many weeks will Sanjay need to ride his bike to work in order to ride 150 kilometers?
Sanjay needs to ride his bike for 3 weeks to cover a distance of
150 kilometers.
What is a unitary method?A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.
Given, Sanjay rides his bike to work 15 kilometers in two days.
∴ In one day he rides (15/2) = 7.5 kilometers.
So, to ride his bike for 150 kilometers he needs (150/7.5) = 20 days.
We know 1 week is 7 days.
∴ Sanjay needs (20/7) = 2.86 weeks, but weeks comes in integers and we'll choose 3 weeks as in 2 weeks he won't be able to cover a distance of 150 kilometers.

Beatrice's house is assessed at $102,000 and her property tax rate is 3.6%. How much are her annual property taxes?
Answer:
The annual property taxes is $3672 .
Step-by-step explanation:
As given in the question
Beatrice's house is assessed at $102,000 and her property tax rate is 3.6%.
3.6% is written in the decimal form
[tex]= \frac{3.6}{100}[/tex]
= 0.036
Property tax price = 0.036 × $102000
= $3672
Therefore the annual property taxes is $3672 .

A radio station gives away $15 to every 15th caller, $25 to every 25th caller, and free concert tickets to every 100th caller. When will the station first give away all three prizes to one caller? PLEASE HELP. Show your work !!
We want to find the lowest common multiple of 3 numbers.
We will see that the 300th caller will get the 3 prizes.
Ok, we know that:
each 15th caller gets $15.each 25th caller gets $25.each 100th caller gets free concert tickets.We want to see the first time that the 3 prizes will be given at the same time (at the same caller).
This will happen for the lowest common multiple of 15, 25 and 100
Now, to find the lowest common multiple we can use brute force, this is, writing all the multiples of the 3 numbers and watching which one is the first to appear in the 3 lists, but here we can do another thing.
One of the numbers is 100, so its multiples are:
100, 200, 300.
And we know that with 25 we can make all of these numbers:
25*4 = 100
25*8 = 200
25*12 = 300
So all the multiples of 100 are also multiples of 25.
Then we just need to find the first common multiple between 100 and 15.
To get this, we can decompose both numbers as a product of primes:
15 = 3*5
100 = 10*10 = 2*5*2*5
Now we multiply these, but if there is some factor that appears in both numbers we remove it (only from one).
For example, here we can see that the factor 5 appears in both numbers, so we need to remove one of the fives in the product.
We will get:
(3*5)*(2*5*2) = 300
So the lowest common multiple is 300.
This means that the 300th caller will get the 3 prizes.

A researcher wants to know if the average time in jail for robbery has increased from what it was when the average sentence was 7 years. he obtains data on 400 more-recent robberies and finds an average time served of 7.5 years. find a 95% confidence interval for the average time served (assume jail time follows a normal distribution with standard deviation 3 years).
At 95% confidence interval, the z score is 1.96. Using the formula:
Confidence Interval = x ± z s / sqrt (n)
where x is the average time served, s is standard deviation and n is number of samples
Confidence interval = 7.5 ± (1.96 * 3) / sqrt (400)
Confidence interval = 7.5 ± 0.294
Confidence interval = 7.206 to 7.794
