Answer:
x =14
<A = 7x -11 = 87
<B = 2x-3 = 25
<C = 5x -2 = 68
Step-by-step explanation:
The sum of the angles add to 180
7x -11 + 2x-3 + 5x-2 = 180
Combine like terms
7x +2x+5x -11-3-2 =180
14x-16=180
Add 16 to each side
14x-16+16 =180+16
14x = 196
Divide each side by 14
14x/14 =196/14
x =14
<A = 7x -11 = 7*14 -11 = 98-11 = 87
<B = 2x-3 = 2*14 -3 = 28-3 = 25
<C = 5x -2 = 5*14 -2 = 70-2 = 68

A finite sequence of numbers is called AWESOME if each subsequent member of the sequence, except the first one, is larger than the previous one and if the
product of all the members of that sequence is a perfect square. For example, sequence 2, 6, 27 is an AWESOME sequence. Determine the natural numbers x and y such that the sequence 28, x, y, 65 is an AWESOME sequence.
Answers
Answer:
The answer is "28, 35, 52, 65"
Step-by-step explanation:
Calculating the x,y:
[tex]\to x< y<65\\\\\to 65 \times 28 xy=13 \times 5xy \times 7 \times 2^2\\\\x=13 \\\\y=5 \times 7= 35\\\\[/tex]
When
or
[tex]x=35\\\\y= 13 \times 2^2=13 \times 4 =52[/tex]
So, the final answer is "28, 35, 52, 65".

What is the solution to the equation? a+5 2/3=9
Answers
Answer:
a=8+1/2
Step-by-step explanation:
We move all terms to the left:
(a+5)2/3-(9)=0
We multiply all the terms by the denominator
(a+5)2-9*3=0
We add all the numbers together, and all the variables
(a+5)2-27=0
We multiply parentheses
2a+10-27=0
We add all the numbers together, and all the variables
2a-17=0
We move all terms containing a to the left, all other terms to the right
2a=17
a=17/2
a=8+1/2

Help me please I will give brainleist
Answers
Answer:
? = 7x
Step-by-step explanation:
Lets simplify the equation first;
5x - 20 + ? = -20 + 12x
=> So now, we have to make the equation on the left equation congruent to the right equation:
It we already have -20 common on both sides, but we need to find out, what added by 5x gives us 12x,
=> So we can let the number we have to find out be y, and say:
5x + y = 12x
=> y = 12x - 5x
=> y = 7x
Therefore, ? = 7x

A culture of the bacterium Salmonella enteritidis initially contains 50 cells. When introduced into a nutrient broth, the culture grows at a rate proportional to its size. After 1.5 hours, the population has increased to 775. (a) Find an expression for the number of bacteria after t hours. (Round your numeric values to four decimal places.)
Answers
Answer:
The expression for the number of bacteria after t hours is [tex]P(t) = 50e^{0.2922t}[/tex]
Step-by-step explanation:
When introduced into a nutrient broth, the culture grows at a rate proportional to its size.
This means that the size of the population, after t hours, is modeled by the following differential equation:
[tex]\frac{dP}{dt} = rP[/tex]
In which R is the growth rate.
The solution of this differential equation is:
[tex]P(t) = P(0)e^{rt}[/tex]
In which P(0) is the initial population.
A culture of the bacterium Salmonella enteritidis initially contains 50 cells.
This means that [tex]P(0) = 50[/tex], and so:
[tex]P(t) = P(0)e^{rt}[/tex]
[tex]P(t) = 50e^{rt}[/tex]
After 1.5 hours, the population has increased to 775.
This means that [tex]P(1.5) = 775[/tex]. We use this to find r. So
[tex]P(t) = P(0)e^{rt}[/tex]
[tex]500e^{1.5r} = 775[/tex]
[tex]e^{1.5r} = \frac{775}{500}[/tex]
[tex]\ln{e^{1.5r}} = \ln{\frac{775}{500}}[/tex]
[tex]1.5r = \ln{\frac{775}{500}}[/tex]
[tex]r = \frac{\ln{\frac{775}{500}}}{1.5}[/tex]
[tex]r = 0.2922[/tex]
The expression is:
[tex]P(t) = 50e^{rt}[/tex]
[tex]P(t) = 50e^{0.2922t}[/tex]
The expression for the number of bacteria after t hours is [tex]P(t) = 50e^{0.2922t}[/tex]
