Answer:
4
Step-by-step explanation:
In mathematics, the square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 4 is 2, because 2 x 2 = 4. The square root of 9 is 3, because 3 x 3 = 9.
The square root of 16 is 4, because 4 x 4 = 16. Therefore, the value of the square root of 16 is 4.
PLS HELP ME!!!!! Students are selling raffle tickets for a school fundraiser. They collect $24 for every 10 raffle tickets they sell. Suppose M is the amount of money the students collect for selling R raffle tickets. Write an equation that reflects the relationship between M and R.
Answer: M=2.4R
Step-by-step explanation:
If 24 dollars are collected for every 10 tickets we can find the cost of each ticket like so...
24/10=2.4
so now we can set up our equation...
M=2.4R
this means we get M amount of money for R number of tickets sold at a rate of $2.40 each.

● The short and long hands of a clock are 4 cm and 6 cm long respectively. Find the sum of distance travelled by their tips in 2 days.
Class - 10th
No spam ❌
Juniors stay away ~
Step by step explanation please
Step-by-step explanation:
short hand radius = 4
distance travellled in 1 day revolution = 2πr= 2 x 22/7 x 4= 25.1cm (approx)
distance travellled in 2 day revolution= 25.1+ 25.1 = 50.2
long hand radius= 6
each hour 1 revolution by long hand so in 24 hr 24 revolutions and 48 he 48 revolution
distance travelled in 1 hr = 2πr= 2 x 22/7 x 6= 37.7
distance in 48hr = 37.7 x 48= 1809.6 (approx)
so sum of both= 1809.6 + 50.2 = 1859.8
Answer:
1910.12 cm
Step-by-step explanation:
2 days = 48 hrs = 2880 mins
One cycle of the short hand (4 cm) would be 12 hrs.
48/12 = 4 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 4 cm
2*pi*4 ≈ 25.13 cm (I only rounded to the hundredth, adjust as u need)
25.13 * 4 = 100.52 cm
One cycle of the long hand (6 cm) would be 60 mins (which is 1hr and two days would be 48hrs or 48 cycles. But let's keep this consistent).
2880/60 = 48 cycles
Circumference of a circle = [tex]2\pi r[/tex]
r = 6 cm
2*pi*6 ≈ 37.70 cm (I only rounded to the hundredth, adjust as u need)
37.70 * 48 = 1809.6
100.52 + 1809.6 = 1910.12 cm

Se tienen dos libros: uno de 240 página y otro de 160 páginas. Si los 2 libros están formados por cuadernillos con el mismo número de páginas (entre 16 y 28), ¿cuántos cuadernillos tienen en total los dos libros?
Answer:
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
Total booklets both the books have in total = 20
Step-by-step explanation:
Given - There are two books: one of 240 pages and the other of 160 pages. If the 2 books are made up of booklets with the same number of pages (between 16 and 28),
To find - How many booklets do the two books have in total?
Proof -
Given that, Number of pages of a booklet is between 16 and 28.
So, The number that lies between 16 and 28 will have to divide the number of pages of both the books.
(Because given that both the books are made up of booklet with the same number of pages)
By inspection, we get
The number of pages of a booklet = 20
because
240/20 = 12 and 160/20 = 8
∴ we get
1 booklet = 20 pages
i.e.
20 pages = 1 booklet
⇒1 page = [tex]\frac{1}{20}booklet[/tex]
⇒240 pages = [tex]\frac{240}{20}booklet[/tex] = 12 booklet
So, we get
The book of 240 pages has 12 booklets in it.
Now,
1 page = [tex]\frac{1}{20}booklet[/tex]
⇒160 pages = [tex]\frac{160}{20}booklet[/tex] = 8 booklet
So, we get
The book of 160 pages has 8 booklets in it.
∴ we get
Book of 240 pages has 12 booklets in total
Book of 160 pages has 8 booklets in total.
So, Total booklets both the books have = 12 + 8 = 20

A standardized test is designed so that scores have a mean of 50 and a standard deviation of 4.
What percent of scores are between 46 and 54?
Answer:
68.3%
Step-by-step explanation:
Using the relation :
Zscore = (x - Mean) / standard deviation
For, x between 46 and 54
Zscore = ((54 - 50) / 4) - ((46 - 50) / 4)
P(Z < 4/4) - P(Z < -4/4)
P(Z < 1) - P(Z <-1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%
= 68.3%

The dollar value v(t) of a certain car model that is t years old is given by the following exponential function.
v (c) = 20,000(0.88)
Find the initial value of the car and the value after 11 years.
Round your answers to the nearest dollar as necessary.
Initial value:
Value after 11 years:
9514 1404 393
Answer:
initial value: $20,000after 11 years: $4,902Step-by-step explanation:
Assuming your equation is ...
v(t) = 20,000(0.88^t)
The value for t=0 is 20,000.
The value for t=11 is 20,000(0.88^11) ≈ 4,902.
The initial value is $20,000; the value after 11 years is $4,902.

Two numerical patterns are shown below:
Pattern A: 6, 12, 18, 24, 30
Pattern B: 12, 24, 36, 48, 60
Select the statement that describes the numerical patterns.
The rule for Pattern B is "multiply by 2."
The rule for Pattern A is "multiply by 2."
Each term in Pattern B is one half the corresponding term in Pattern A.
Each term in Pattern A is one half the corresponding term in Pattern B.
Answer:
ITS A
i took the quiz :)
Step-by-step explanation:
The two true statements are:
The rule for Pattern B is "multiply by 2."
Each term in Pattern A is one-half the corresponding term in Pattern B.
Wich statements are the correct ones?
Here we have two patterns:
Pattern A: 6, 12, 18, 24, 30Pattern B: 12, 24, 36, 48, 60First, let's analyze the patterns. For pattern A we can see that we just add 6 to each consecutive term, so this is an arithmetic sequence.
6 + 6 = 12
12 + 6 = 18
18 + 6 = 24
And so on.
For pattern B we multiply each term by 2 to get the next one, so this is a geometric sequence.
2*12 = 24
2*24 = 48
and so on.
Then we already can see that. "The rule for Pattern B is "multiply by 2." Is true
And:
The rule for Pattern A is "multiply by 2." is false.
Finally, let's compare the terms. The first term of B is 12, and the first ter of A is 6, so we can see that the first term of B is two times the first one of A. The second term of B is 24, while the second of A is 12, so again, we can see that the second term of B is two times the second of A.
So we can see a pattern, meaning that the statement: "Each term in Pattern A is one-half the corresponding term in Pattern B."
Is true.If you want to learn more about sequences, you can read:
