A thread was folded in half, and then it was folded again, forming a bundle. Then the thread was cut into pieces by a striaght cut through the enitre bundle. Ine of the pieces is 8 cm, and the longest piece is 18 cm. What is the longest possible length of the thread
The longest possible length of the thread is;
Length = 144 cm
Let the length of the thread be x cm.
Now, it is first folded in half. This means divided into 2. Thus, we now have length as x/2.
We are told it is folded again. This means the length after second folding is now; (x/2) ÷ 2 = x/4.We are told that there is now a straight cut through the entire bundle with one of the pieces being 8cm and the longer piece being 18 cm.This means the ratio is; 8:18
Since the new length after the final folding is x/4, then it means after cutting;longer length will be; [tex](\frac{18}{8 + 18})[/tex] [tex]* (\frac{x}{4})[/tex]
Thus, we now have;
18 = (18/26) × (x/4)
18 will cancel out to give; x = 26 × 4
x = 144 cm
Therefore the longest possible length of the thread = 144 cm

The temperature at 8:20 P.M. is 3degreesC. If it has dropped 1degreesC per minute, what was the temperature at 7 : 50 P.M.?
Answer:
33°C
Step-by-step explanation:
The time between 8:20 and 7:50 is 30 minutes. If it drops 1°C per minute you multiply this number by the amount of minutes which would be 30. This becomes 30°C. Then add the 3° it's at now to become 33°C.
Evaluate each function for the given input values. For f (x)=x 2- 5, find f (x) when x= 0 and when x= 3
Answer:
f(x) = x² - 5
so f(0) = 0² - 5 = 0 - 5 = - 5
and f(3) = 3² - 5 = 9 - 5 = 4
Point A has coordinates (-5, 3). If point (1,6) is
of the way from A to B what are the coordinates of point B?
Answer:
[tex](3, 7)[/tex]
Step-by-step explanation:
(4/3)P -(4/3)A + A = B . . . . . . add A
(4P -A)/3 = B . . . . . . . . . . . . . simplify
Then the coordinates of point B are ...
B = (4(1, 6) -(-5, 3))/3 = (9, 21)/3
B = (3, 7)

Answer: Sin(©)=4/5
Step-by-step explanation: Cos(©)=3/5
Sin(©)=?
By Trigonometric identity,
Sin²(©) + Cos²(©) = 1
Sin²(©) = 1- Cos²(©)
Cos²(©) = (3/5)² = 9/25
Sin²(©) = 1- 9/25 = 16/25
Taking the root of both sides,
√(Sin²(©)) = √(16/25)
Hence, Sin(©) = 4/5

An arts academy requires there to be 6 teachers for every 144 students and 5 tutors for every 40 students. How many students does the academy have per teacher? Per tutor? How many tutors does the academy need if it has 72 students
Answer:
3 teachers and 9 tutors
Step-by-step explanation:
Answer:
There are 24 students per teacher and 8 students per tutor. If the academy has 72 students, then 9 tutors would be needed.
Step-by-step explanation:
We will start with the question, how many students does the academy have per teacher. To find this, we need to set up the equation. 144 will be the number of students, 6 will be the number of teachers, and x will be the number of students per teacher.
144/6=x
24=x
So, there are 24 students for every teacher.
We could also do this as a ratio. We would do the same thing. We would divide by six to get our answer.
144:6
Make the six one.
24:1
This shows that there are 24 students for every teacher.
Now to find out how many per tutor.
We will do the same thing as before, minus the ratio, though you could still use the ratio. Remember, 40 is the number of students, 5 is the number of tutors, and x is the number of students per tutor.
40\5=x
8=x
So there are 8 students per tutor.
Now we will use this knowledge to solve for how many tutors are needed if the academy has 72 students.
We will set up our equation. 72 will be the students, we will use eight since that is how many students are needed per tutor, and x will be the number of tutors needed.
72/8=x
9=x
So this means that if the academy has 72 students, then it will need 9 tutors.
y raise to power 1/2 =3
Answer:
y = root 9
Step-by-step explanation:
1/2 is equivalent to the root of something.
The root of y equals 3.
Therefore, y would be equal to root 9, as root 9 is equivalent to 3.
Hope this helps :)
y^1/2 = 3
√y = 3
Raise both sides to power 2
( √y )^2 = ( 3 )^2
y = 9

Huilan is 5 years older than Thomas. The sum of their ages is 57. What is Thomas's age?
Answer:
21
Step-by-step explanation:
You can write this question out with two separate formulas, the first one being H - 5 = T, and the second being H + T = 57. I am using the variables of H and T to show the ages of Hulian and Thomas respectively. From here, we can use the substitution formula since we already know what T is equal to (H - 5). Substituting the equation in, we get a new equation of H + (H + 5) = 57. Subtracting 5 from both sides gives us the equation of H + H = 52, or 2H = 52. Dividing by 2 yields the answer of 26 for Hulian's age. Since we know that Hulian is 5 years older than Thomas, we can subtract 5 from 26, giving us Thomas' age, which is 21.
Answer:
23.5
Step-by-step explanation:
=57/2
=28.5-5
=23.5
thomas is 23 years and 6 months old

Answer:
B. 1.5
Step-by-step explanation:
To turn a fraction into a decimal, make the denominator (the bottom number) 100 since you are only using the tenths place of a decimal:
1/2 x 50/50 = 50/100 = 0.5
Then add the whole number:
1 + 0.5 = 1.5
