HELP IM STUCK ON THIS QESTION!!!
Answer: 3.81
Step-by-step explanation:
Answer:
3.81
Step-by-step explanation:
1. We assume, that the number 25.4 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 25.4 is 100%, so we can write it down as 25.4=100%.
4. We know, that x is 15% of the output value, so we can write it down as x=15%.
5. Now we have two simple equations:
1) 25.4=100%
2) x=15%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
25.4/x=100%/15%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 15% of 25.4
25.4/x=100/15
(25.4/x)*x=(100/15)*x - we multiply both sides of the equation by x
25.4=6.66666666667*x - we divide both sides of the equation by (6.66666666667) to get x
25.4/6.66666666667=x
3.81=x
x=3.81
Solve for the unknown variable.
5x + 2( 5x - 9) = 27

A toddler was given 12 boxes of crayons, each of which contained 12 crayons. Within a week, he eventually lost half of the crayons and broke a quarter of the remaining crayons. How many intact crayons did the toddler have at the end of the week?
Answer:
6
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
You would do 12 • 12 which gets you the number of crayons they first had, then divide by 2 which tell you how many crayons they have after losing half then divide by 4 which tell you the number they have after breaking the crayons.

Let t represent an unknown number. What is the value
oft such that: t^2 x^3– 3tx + 6 is divisible by x+3.
There are two possible answers:
t = 2/3 or t = -1/3
========================================================
Explanation:
The expression x+3 is the same as x-(-3). It is of the form x-k
Recall that by the remainder theorem, we know that p(x) is divisible by (x-k) if and only if p(k) = 0.
In this case, k = -3. Plug this into the p(x) function and we get
p(x) = t^2*x^3 - 3t*x + 6
p(-3) = t^2*(-3)^3 - 3t*(-3) + 6
p(-3) = -27t^2 + 9t + 6
Set that equal to 0
p(-3) = 0
-27t^2 + 9t + 6 = 0
-3(9t^2 - 3t - 2) = 0
9t^2 - 3t - 2 = 0
Now apply the quadratic formula to solve for t
[tex]t = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\t = \frac{-(-3)\pm\sqrt{(-3)^2-4(9)(-2)}}{2(9)}\\\\t = \frac{3\pm\sqrt{81}}{18}\\\\t = \frac{3\pm9}{18}\\\\t = \frac{3+9}{18}\ \text{ or } \ t = \frac{3-9}{18}\\\\t = \frac{12}{18}\ \text{ or } \ t = \frac{-6}{18}\\\\t = \frac{2}{3}\ \text{ or } \ t = -\frac{1}{3}\\\\[/tex]
We get two possible solutions for t.

What is the sequence of the n^"th" term equation f(n) = -3n +7 for n 1
Answer:
The sequence of the given equation
4 , 1, -2 , -5, ......
∴ The given sequence is in Arithmetic progression ( A.P)
Step-by-step explanation:
Step(i):-
Given [tex]n^{th}[/tex] term of thesequence
f (n) = - 3n + 7
Put n = 1
first term a₁ = f (1 ) = - 3 (1 ) + 7 = - 3 + 7 = 4
Put n = 2
second term a₂ = f(2) = - 3 ( 2) + 7 = -6 +7 =1
Put n =3
Third term a₃ = f(3) = -3(3) +7 = -9 + 7 = -2
Put n =4
Fourth term a₄ = f(4) = -3(4) +7 = -12 + 7 = -5
Step(ii):-
The sequence of the given equation
4 , 1, -2 , -5, ......
first term a = 4 , d = 1 -4 = -3
The difference of two terms in this sequence is equal
∴ The given sequence is in Arithmetic progression ( A.P)
Final answer:-
The sequence of the given equation
4 , 1, -2 , -5, ......
∴ The given sequence is in Arithmetic progression ( A.P)
