find the value of x in the angle
Answers
Answer:
The answer would be B
Step-by-step explanation:
Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle. If you are working with equilateral triangles, divide 180 by three to find the value of X.
Solve the inequality. 5(x + 1) – 10 ≥ 2x + 3(x + 2)
Answers
No solution.
The solution of the inequality 5(x + 1) - 10 ≥ 2x + 3(2x + 2) is x ≤ - 16/3.
What are inequalities and their types?Inequality is a relation that compares two numbers or other mathematical expressions in an unequal way.
The symbol a < b indicates that a is smaller than b.
When a > b is used, it indicates that a is bigger than b.
a is less than or equal to b when a notation like a ≤ b.
a is bigger or equal value of an is indicated by the notation a ≥ b.
Given, Inequality is 5(x + 1) - 10 ≥ 2x + 3(2x + 2).
5x + 5 - 10 ≥ 2x + 6x + 6.
5x + 5 - 10 ≥ 8x + 6.
5x - 8x ≥ 10 + 6.
- 3x ≥ 16.
3x ≤ - 16.
x ≤ - 16/3.

[tex]\displaystyle \log_7\frac{1}{81}\approx -2.2[/tex]
Step-by-step explanation:
We want to find:
[tex]\displaystyle \log_7{\frac{1}{81}}[/tex]
First, using the quotient rule:
[tex]\displaystyle \log_b\frac{a}{c}=\log_b a-\log_b{c}[/tex]
We can rewrite our expression as:
[tex]=\log_7 1-\log_7 81[/tex]
The logarithm of 1 is always 0. Therefore:
[tex]=-\log_781[/tex]
We can rewrite this as:
[tex]=-\log_7 9\cdot 9[/tex]
Using the product rule:
[tex]\log_b ac=\log_ba+\log_bc[/tex]
This is equivalent to:
[tex]=-(\log_79+\log_79)[/tex]
Substitute:
[tex]=-(1.1+1.1)=-2.2[/tex]

Adrian invested $790 in an account paying an interest rate of 6.9% compounded continuously. Assuming no deposits or withdrawals are made, how long would it take, to the nearest year, for the value of the account to reach $2,550?
Answers
Answer:17
Step-by-step explanation:
trust me its right, no cap
As per compound interest, it would take 17 years for the value of the account to reach $2,550
What is the compound interest?If the invested amount is 'P', the rate of interest is r%, and the time of investment is 'n' years, then the compound interest after mentioned duration is = P[1 - [tex]e^{rn}[/tex]]
Given, the invested amount (P) = $790.
Rate of interest (r) = 6.9% = 0.069.
Let, the amount is invested for 'n' years.
The value of the amount after 'n' years = $2550.
Now, as per compound interest:
A = P. [tex]e^{rn}[/tex]
⇒ 2550 = 790 [tex]e^{(0.069n)}[/tex]
⇒ [tex]e^{(0.069n)}[/tex] = (2550 ÷ 790)
⇒ [tex]e^{(0.069n)}[/tex] = 3.23
⇒ 0.069n = 1.172
⇒ n = 17
