Daniel has 53 paintbrushes in his art drawer. This is 25% of the total number of paintbrushes he has. How many paintbrushes does he have in all?
Answer:
Total number of paintbrushes
= 53 ÷ 25%
= 53 ÷ 0.25
= 212
Answer:
If 53 paintbrushes represent 25% of the total number of paintbrushes Daniel has, we can use the following formula to find the total:
total number of paintbrushes = (number of paintbrushes / percentage) x 100
Plugging in the values we know, we get:
total number of paintbrushes = (53 / 25) x 100
Simplifying, we get:
total number of paintbrushes = 212
Therefore, Daniel has a total of 212 paintbrushes in all.
A film show lasted for 3 3/2 hours. Out of this ,1 1/3 hours were spent on advertisements. What was the actual duration of the film
3 3/2 hours as a decimal= 4.5
1 1/3 hours as a decimal = 1.3
Duration of the film show = 4.5 hours
Hours spent on advertisements = 1.3 hours
Actual duration of the film = 4.5 - 1.3 hours
= 3.2 hours
3.2 hours as a fraction = 3 1/5 hours.
Therefore, the actual duration of the film was 3 1/5 hours.

Answer: it's C
Step-by-step explanation:
Answer:D
Step-by-step explanation:
To indirectly measure the distance across a lake, Dominic makes use of a couple landmarks at points � B and � C. He measures � � AD, � � DB, and � � DE as marked. Find the distance across the lake ( � � ) (BC), rounding your answer to the nearest hundredth of a meter.
The distance across the lake is approximately 62.5 meters, rounded to the nearest hundredth of a meter.
To find the distance across the lake (BC), we can use the following formula based on triangle similarity:
BC/AD = DB/DE
Where BC is the distance across the lake, AD is the known direct measurement made by Dominic, DB is the known measurement from point B to the landmark, and DE is the known measurement from point D to the landmark.
Let's assume that AD = 100 meters, DB = 50 meters, and DE = 80 meters. Then we can calculate BC as follows:
BC = (BC/AD) * AD = (DB/DE) * AD
BC = (50/80) * 100
BC = 62.5 meters
So, the distance across the lake is approximately 62.5 meters, rounded to the nearest hundredth of a meter.

A ball is dropped from 2 meters and rises up by 75%
When a ball is droped from 2m heights and rises by 75%, then the height of ball after forth bounce is equals to 0.632 meters.
If an object is thrown from high and has a bouncing feature, each bouncing is less than the initial height until it stops. Each bounce reduces the growth rate until it reaches zero. In order to calculate the height of each bounce, so we can estimate what percentage the object will reach after each bounce. If we get the percentage of each bounce, we can easily determine the height of each bounce. We have, a ball is droped from 2 meters and bounce up to 75%. That is height of first bounce is determined by using percentage, height is 2 m × 75% = 2 m×0.75 = 1.5 m
In second bounce, height is 1.5 m × 75%
= 1.5 m×0.75 = 1.12 m
In third bounce, 1.12 m× 75%

Suppose you know that ∠S and ∠Y are complementary and that m∠S = 5(m∠Y) − 240°. Find m∠Y.
The measure of angle Y, according to the stated statement, is 55 degrees.
What does the term "complementary" mean?An adverb used to describe something which goes together with something else and improves or completes it is complimentary (as in complementary colors)
The total of two complimentary angles is 90 degrees. As a result, we have:
m∠S + m∠Y = 90
Substituting the given equation m∠S = 5(m∠Y) − 240°, we get:
5(m∠Y) − 240° + m∠Y = 90
By merging like variables in the equation, we can reduce it to:
6(m∠Y) - 240° = 90
Adding 240 to both sides, we get:
6(m∠Y) = 330
Dividing both sides by 6, we get:
m∠Y = 55
Therefore, the measure of angle Y is 55 degrees.

are square with side lengths 11
3 feet. How many tiles are needed to cover the entire
floor? Show your reasoning.
165 tiles are needed to cover the entire floor of the room.
First, we need to find out the area of the room in square feet. We do this by multiplying the length and width of the room:
12 feet x 15 feet = 180 square feet
Next, we need to find out the area of one tile in square feet. We do this by squaring the length of one side of the tile:
11 3/11 feet x 11 3/11 feet = 128/121 square feet
Now, we can divide the total area of the room by the area of one tile to find out how many tiles are needed:
180 square feet / (128/121 square feet) = 180 x 121/128 = 165 tiles
So, 165 tiles are needed to cover the entire floor of the room.

A particle is moving along a spiral path defined by the equation r = a * e^(b * θ), where a and b are constants. Determine the velocity of the particle at a given value of θ.
Step-by-step explanation:
The velocity of the particle at a given value of θ can be found by taking the derivative of the position vector with respect to time:
v(θ) = dr/dt = dr/dθ * dθ/dt = dr/dθ * ω
where ω is the angular velocity and dr/dθ is the derivative of the position vector with respect to θ.
The position vector r = a * e^(b * θ) * i + a * b * e^(b * θ) * j
Taking the derivative with respect to θ:
dr/dθ = a * b * e^(b * θ) * i + a * b^2 * e^(b * θ) * j
So the velocity of the particle is given by:
v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * j
Answer:
Step-by-step explanation:
v(θ) = a * b * e^(b * θ) * ω * i + a * b^2 * e^(b * θ) * ω * jj
A company’s stock opened at 68 3/8 dollars per share. The stock dropped 1 7/8 dollars on Monday. The stock dropped another 2 1/2 dollars on Tuesday. On Wednesday, the stock gained back 4 1/4 dollars. brainly
Answer:
273/4
Step-by-step explanation:
We know
A company’s stock opened at 68 3/8 dollars per share
68 3/8 = 547/8
The stock dropped 1 7/8 dollars on Monday
1 7/8 = 15/8
547/8 - 15/8 = 532/8
The stock dropped another 2 1/2 dollars on Tuesday.
2 1/2 = 5/2
532/8 - 5/2 = 532/8 - 20/8 = 512/8
On Wednesday, the stock gained back 4 1/4 dollars.
4 1/4 = 17/4
512/8 + 17/4 = 512/8 + 34/8 = 546/8
546/8 = 273/4
So, the answer is 273/4

. If gcd(a, b)-p, a prime, what are the possible values of gcd(a2, b2), gcd(a2, b), and gcd(a3, 2)?
The possible values are -
(a²,b²) = p
(a²,b) = p if p|-r and (a²,b) = p² if p|r
(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r
What is gcd?
The greatest common factor (GCF) that divides two or more numbers is known as the greatest common divisor (GCD). The highest common factor is another name for it (HCF).
Since (a, b) = p it can be written a = pr and b = ps where r and s are integers such that (r, s) = 1.
Then a² = p²r².
Then by Theorem 1.7, (a²,b) = (p²r²,ps) = p(pr²,s).
By Theorem 1.8, (r²,s) = 1 .
Thus, there are two cases to consider: if p|s then, (a²,b) = p², and if p|-s then (pr²,s) = 1 (Again by Theorem 1.8) so that (a²,b) = p in that case.
Thus, there are two cases for (a²,b): namely p or p².
The same analysis shows that (a³,b) must be either p, p² or p³ depending on the power of p that divides b.
Analyze (a²,b³) as follows.
Using the notation already introduced, and
Theorem 1.7, it is obtained that (a²,b³) = (p²r²,p³s³) = p²(r²,ps³).
Since, (r, s) = 1, Theorem 1.8 shows that (r²,s³) = 1.
Therefore, there are two possibilities for (a²,b³) -
(a²,b³) = p² if p|-r and (a²,b³) = p³ if p|r.

What is the length of DF?In this problem, we have to apply the Pythagorean theorem to find the lenght of DF line.
a² + b² = c²
7² + b² = 8²
49 + b² = 64
b² = 15
b = 3.87

A passenger train and a freight train leave cities 260 mi apart and travel toward each other. The passenger train is traveling
15 mph faster than the freight train. Find the speed of each train if they pass each other after 4 hr.
Step-by-step explanation:
x = speed of the passenger train
x - 15 = speed of the freight train
remember, the passenger train is traveling 15 mph faster than the freight train. that also means the freight train travels 15 mph slower than the passenger train.
we could define the variable also the other way around (x = freight train, x + 15 = passenger train).
speed = distance/time period
distance = speed × time period
so,
x×4 + (x - 15)×4 = 260
because when both trains meet somewhere in the middle, it means that the sum of both of their ways traveled is the whole distance between both cities : 260 miles.
4x + 4x - 60 = 260
8x = 320
x = 320/8 = 40 mph
so, the passenger train traveled at 40 mph.
the freight train traveled at 40-15 = 25 mph.

an arithmetic sequence with first term 1 and common difference not equal to 0 has second, tenth, and thirty-fourth terms that form a geometric sequence. what is the thirty-fourth term of the arithmetic sequence?
The thirty-fourth term of the arithmetic sequence is the thirty-second term plus the common difference, which is not equal to 0.
The thirty-fourth term of the arithmetic sequence is calculated by adding the common difference to the thirty-second term. The common difference is the amount by which each successive term increases or decreases. As the common difference is not equal to 0, the thirty-fourth term is not the same as the tenth or second terms. The second, tenth, and thirty-fourth terms form a geometric sequence, which means that the ratio between any two successive terms is always the same. This ratio is determined by the common difference of the arithmetic sequence, and the thirty-fourth term can be calculated by adding the common difference to the thirty-second term.
