Answer:
x= 2
Step-by-step explanation:
Subtract 20 from both sides
2.5x + 20 − 20 = 25 − 20
2.5x= 5
Divide both sides by 2.5
2.5x/2.5= 5/2.5
x= 2

James works at a toy store, and he notices that at the end of his first hour 32% of all the toys have been sold. At the end of his second hour, 32% of the toys that were there at the end of the first hour had been sold, and so on. Write a recursive function for what percent of toys, t, are still in the still after n hours have passed.
Assuming he started with 300 toys, and James can go home when there are less than 5 toys left, how many hours will James be working, assuming they check the toy count every hour? If the function only keeps track of how many toys there are while James is working, what does the domain of the function become?

Evaluate: C(14, 10)
no pic just answer it
Given:
The combination C(14,10).
To find:
The value of the given combination.
Solution:
We know that,
[tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]
Using this formula, we get
[tex]C(14,10)=\dfrac{14!}{10!(14-10)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11\times 10!}{10!(4)!}[/tex]
[tex]C(14,10)=\dfrac{14\times 13\times 12\times 11}{4\times 3\times 2\times 1}[/tex]
[tex]C(14,10)=7\times 13\times 11[/tex]
[tex]C(14,10)=1001[/tex]
Therefore, the value of C(14,10) is 1001 and the correct option is B.
The equivalent expression of "[tex]C(14,10)[/tex]" is "1001".
Equivalent expression:using formula:
[tex]\to ^n C_r=\frac{n!}{r!(n-r)!}[/tex]
putting the given value into the above formula:
[tex]\to ^{14} C_{10}=\frac{14!}{10!(14-10)!}[/tex]
[tex]=\frac{14 \times 13 \times 12 \times 11 \times 10! }{10! \times 4 \times 3 \times 2 \times 1}\\\\=\frac{14 \times 13 \times 12 \times 11 }{ 4 \times 3 \times 2 \times 1}\\\\={7 \times 13 \times 11 }{}\\\\=1001[/tex]
Therefore, the final answer is "1001".

Ben put $6,500 into a savings account that earns 2.5% interest each year. How much interest will he earn after 6 years in the savings account?
Answer:
$1,038
Step-by-step explanation:
the equation for annual compound interest is y=p(1±r)^t, where p is the principal (starting amount), r is the rate (as a decimal), and t is the number of years (time).
2.5% as a decimal is 0.025
We will add that to 1, because when we earn interest, we are gaining money.
So we will substitute our given numbers into the equation:
y=6500(1.025)^6
solve:
y=$7,5638 (rounded)
That's the total amount he earned (principal + interest). To find out how much interest he earned over those 6 years, subtract our new amount from our starting amount
75638-6500
$1,038
So he made $1,038 in interest
Round the following real number to the nearest hundredth: 67.498
Answer:
67.50
Step-by-step explanation:
Answer:
67.5The hundredth is always the second number after the decimal point (to the right).
So, when rounding to that number look at the number on the right of it, which in this case is 9.
Then, if the number is 5 to 9, round up, but if it is 0 to 4, round down.
In this case, the number above 0.49 is 0.5.

Answer:
a diagram is necessary. please provide a diagram.
The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°
What is mean by Angle?An angle is a combination of two rays with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Reference angle = R
Side opposite to R = 5 cm
Adjacent side length = 12 cm
Thus, applying TOA, we have:
Tan R = opposite/adjacent
Tan R = 5/12
R = tan⁻¹ (5/12)
R ≈ 22.62°
Thus, The value of measure of angle R is,
⇒ m ∠R ≈ 22.62°

The dimensions of a box are (x+3),(3x-4),(5x+1). What is the volume of the box? 9x 9x^3 15x^3+28x^2-55x-12
Answer:
15x^3+28x^2-55x-12
Step-by-step explanation:
Dimensions of the box are (x+3), (3x-4), and (5x+1). Let these be length, width and height of the box.
assuming the box is cuboidal
Therefore, volume of the box = Length× width× height
⇒volume of the box = (x+3)×(3x-4)×(5x+1)
now, (x+3)×(3x-4) = (3x^2+5x-12)
Now, volume of the box = (3x^2+5x-12)×(5x+1)
= 15x^3+28x^2-55x-12

Step-by-step explanation:
If the initial velocity stays the same, but the height the projectile is launched from changes , how would the amount of time change that it takes for the projectile to reach its maximum height? How would its maximum height change?
Answer:
Part A
The height to which the projectile reaches is given by the following formula;
[tex]\Delta y = y-y_0 = v_{0y} \times t-\dfrac{1}{2} \times g \times t^2[/tex]
Where;
[tex]v_{0y}[/tex] = The initial velocity of the projectile = Stays the same
y = The height the projectile reaches
y₀ = The height from which the projectile is launched
g = The acceleration due to gravity
t = The time taken
Given that the projectile has the same initial velocity, the variation of Δy with time, 't', will be the same when the project is launched from a different height, and the time change that it takes for the projectile to reach the maximum height will be the same for the previous launch height
Part B
From the change in eight of the projectile, Δy = y - y₀, the maximum height reached, 'y', is therefore given as follows;
y = Δy + y₀
The maximum height will increase by 'y₀', where 'y₀' is the difference between new height and the previous height, [tex]y_i[/tex]
That is, if y₀ > [tex]y_i[/tex], the maximum height reached increases and if y₀ < [tex]y_i[/tex], y₀ will be added as y = Δy - y₀ and the maximum height reached decreases

There were 36 sweatshirts on sale for 2/3 of the regular price. What was
the sale price if the regular price was $30?
Answer:
To sum up, we solved for W. Finally, the sale price of a sweatshirt was 20$.
Step-by-step explanation:
So we have our main equation of W/G=p. The G stands for the total amount which is 30. The W is the unknown in this case. As for the p equals 2/3.
Thus we substitute G and p into the equation W/30=2/3. We multiply both sides of the equation with 30 W=2*30/3. Which gives us 60/3=20.
