Answer:
24
Step-by-step explanation:
First we compute the number under the radical.
We have 25² = 625 and 7² = 49, so 25² - 7² = 625 - 49 = 576.
Thus, √25² - 7² = √576 = √24², which is 24.

8. The number of T-shirt sales for a new online store increases by a factor of 3
each month. The function f(x) = 3x
represents the number of T-shirts sold in
month x.
a. What is f(5)?
b. When does the store sell 81 T-shirts?
Answer:
A= 243
B=4
Its because its multiplying itself 5 times for A. And doing it 4 times for B
I think this is correct (I am only in Middle School...)
Step-by-step explanation:
(a) The number of T-shirts sold in the 5th month is 15. (b) The store sells 81 T-shirts in the 27th month.
a. To find f(5), we need to plug x = 5 into the function f(x) = 3x:
f(5) = 3 × 5 = 15
So, the number of T-shirts sold in the 5th month is 15.
b. To find when the store sells 81 T-shirts, we need to solve the equation f(x) = 81:
f(x) = 3x = 81
Now, solve for x:
3x = 81
Divide both sides by 3:
x = 81 / 3
x = 27
So, the store sells 81 T-shirts in the 27th month.

If I start with 2 and count by 8s until I reach 82, I will get: 2, 10, 18, 26, 82, ... , where 2 is the first number, 10 is the second number and so fourth. If 82 is the Nth number, what is the value of N?
Answer:
11 is N
Step-by-step explanation:
Since we know the first answer is 2, we can subtract 82 by 2. Afterwards we can divide by 8 since we are counting by 8s, this gets me 10. 10 + the first number is 11

The factors of the quadratic equation x²- 5x + 4 are (x - 4)(x - 1) option (A) is correct.
What is a quadratic equation ?Any equation of the form [tex]\rm ax^2+bx+c=0[/tex] Where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
We have a quadratic equation:
= x²- 5x + 4
= x² -x - 4x + 4
= x(x - 1) - 4(x - 1)
= (x - 4)(x - 1)
Thus, the factors of the quadratic equation x²- 5x + 4 are (x - 4)(x - 1) option (A) is correct.

Step-by-step explanation:
All radioactive isotopes decay exponentially, the mass of the isotope as a function of time ([tex]m(t)[/tex]), measured in grams, is defined by:
[tex]m(t) = m_{o}\cdot e^{-k\cdot t}[/tex] (1)
Where:
[tex]m_{o}[/tex] - Initial mass of the isotope, measured in grams.
[tex]k[/tex] - Decay rate, measured in [tex]\frac{1}{min}[/tex] or [tex]\frac{1}{day}[/tex] or [tex]\frac{1}{yr}[/tex].
[tex]t[/tex] - Time, measured in minutes, days or years.
We define the decay rate in terms of half-life by using the following expression:
[tex]k = \frac{\ln 2}{t_{1/2}}[/tex] (2)
Where [tex]t_{1/2}[/tex] is the half-life of the isotope, measured in minutes or years.
Now we proceed to determine the missing values:
a) Polonium-200 ([tex]t_{1/2} = 11.5\,min[/tex])
[tex]k = \frac{\ln 2}{11.5\,min}[/tex]
[tex]k \approx 0.0602\,\frac{1}{min}[/tex]
b) Lead-194 ([tex]t_{1/2} = 10.7\,min[/tex])
[tex]k = \frac{\ln 2}{10.7\,min}[/tex]
[tex]k \approx 0.0648\,\frac{1}{min}[/tex]
c) Iodine-125 ([tex]k = 0.0115\,\frac{1}{day}[/tex])
[tex]t_{1/2} = \frac{\ln 2}{k}[/tex]
[tex]t_{1/2} = \frac{\ln 2}{0.0115\,\frac{1}{day} }[/tex]
[tex]t_{1/2} \approx 60.274\,days[/tex]
d) Kryption-75 ([tex]k = 0.161\,\frac{1}{min}[/tex])
[tex]t_{1/2} = \frac{\ln 2}{k}[/tex]
[tex]t_{1/2} = \frac{\ln 2}{0.161\,\frac{1}{min} }[/tex]
[tex]t_{1/2}\approx 4.305\,min[/tex]
e) Strontium-79 ([tex]t_{1/2} = 2.3\,min[/tex])
[tex]k = \frac{\ln 2}{2.3\,min}[/tex]
[tex]k \approx 0.3\,\frac{1}{min}[/tex]
f) Uranium-229 ([tex]t_{1/2} = 58\,min[/tex])
[tex]k = \frac{\ln 2}{58\,min}[/tex]
[tex]k \approx 0.0120\,\frac{1}{min}[/tex]
g) Plutonium-239 ([tex]t_{1/2} = 24100\,yr[/tex])
[tex]k = \frac{\ln 2}{24100\,yr}[/tex]
[tex]k \approx 2.876\times 10^{-5}\,\frac{1}{yr}[/tex]

Answer:

Step-by-step explanation:
i had to figure out how much percent was taking then I added and some subtraction and i got 544
If 1,938 students go to the school, about 1394 students play video games.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given that 1938 students go to school.
And the circle graph represents the number of teenagers at a high school who play video games.
And 259° students out of total angle of circle play video games.
That means 259 percentage of 360,
259 = 360 × percentage of students those play video games of the circle/100
percentage of students those play video games of the circle = 259 x 100 / 360 = 71.94%
And the number of students those play video games is
= 71.94% of 1938
= 1938 x 71.94 / 100
= 1394 students
Therefore, if 1,938 students go to the school, about 1394 students play video games.

A team won 13 games, lost 15 games, and tied 2
games. What percent of its games did the team win? I need help please!!
Answer:
43%
Step-by-step explanation:
First, find the total amount of games:
13 + 15 + 2
= 30
Then, to find the percentage of games won, divide 13 by 30:
13/30
= 0.43
So, the team won approximately 43% of its games
Answer: Approximately 43.3%
Work Shown:
13+15+2 = 30 games total
Divide the number of games won (13) over the number total (30)
13/30 = 0.433 approximately which converts to 43.3% of the games won
To convert from decimal form to percent form, move the decimal point over to the right two spaces. Another example would be 0.83 converts to 83%
5.46 in fraction form HURRY
Answer:
Id assume its 5 23/50..correct me if I'm wrong its been quite some time since I've dealed with decimals to fractions.
Step-by-step explanation:
Answer:
f
Step-by-step explanation:
Do you want to know how to write the decimal number 5.46 as a fraction?
Here we will show you step-by-step how to convert 5.46 so you can write it as a fraction.
You can take any number, such as 5.46, and write a 1 as the denominator to make it a fraction and keep the same value, like this:
5.46 / 1
To get rid of the decimal point in the numerator, we count the numbers after the decimal in 5.46, and multiply the numerator and denominator by 10 if it is 1 number, 100 if it is 2 numbers, 1000 if it is 3 numbers, and so on.
Therefore, in this case we multiply the numerator and denominator by 100 to get the following fraction:
546 / 100
Then, we need to divide the numerator and denominator by the greatest common divisor (GCD) to simplify the fraction.
The GCD of 546 and 100 is 2. When we divide the numerator and denominator by 2, we get the following:
273 / 50
Therefore, 5.46 as a fractio
