x + 38 + 2x + 1 = 180
Once you solve this, you get
x = 47
You can then plug in x to the different sides to find the measure of each angle.
The angle on the left would be
47+38 which is 85
and the angle on the right would be
2(47)+1 which is 95

A chemist want to mix a 40% acid solution with a 70% acid solution to make 6 liters of a 50% acid solution. How much of each type of solution should the chemist use? Show your Work. I NEED HELP ASAP, PLZ HELP
Answers
Answer:
2 liters of 70%
4 liters of 40%
Step-by-step explanation:
Let
x = liters of 70%
Then the remaining amount is
6 - x = liters of 40%
---------------------------------
Mixing
(70% of x) + (40% of 6 -x) (to get) 50% of 6)
70(x) + 40(6-x) = 50(6)
Simplify
70x + (240 - 40x) = 300
Combine like terms
30x = 60
Divde both sides by 30
x = 2 liters of 70%
6 - x = 4 liters of 40%

$2/5lb find unit rate
Answers
Answer:
1$/2.5lb
Step-by-step explanation:
This is a fraction equal to 5 pounds / 2 dollars
We want a unit rate where 1 is in the denominator, so we have to divide the top and bottom by 2.
5 pounds / 2
2 dollars / 2
This should progress to
2.5 pounds/a dollar
This means that the unit rate is 2.5 pounds per dollar.

x = 1 - i sqrt(2) ^ y = 10 + i sqrt(2)
x = 1 + i sqrt(2) ^ y = 10 - i sqrt(2)
Answer:
Step-by-step explanation:
y = 11 - x ----------(I)
y = 2x² - 4x + 6 -----------(II)
Substitute y = 11- x in (II)
11 - x = 2x² - 4x + 6
0 = 2x² - 4x + x + 6 - 11
0 = 2x² - 3x - 5
2x² - 3x - 5 = 0
Sum = -3
Product = -10
Factors = -5 , 2
2x² - 5x + 2x - 5 = 0
x(2x - 5) + (2x - 5) = 0
(2x -5 )(x +1)=0
2x - 5 = 0 ; x + 1 = 0
2x = 5 ; x = -1
x = 5/2
When x = -1 ; y = 11 - (-1) = 11 + 1 = 12
[tex]When x = \dfrac{5}{2} ; y = 11- \dfrac{5}{2}= \dfrac{22}{2}- \dfrac{5}{2}= \dfrac{17}{2}[/tex]

A colony of E. coli bacteria initially has 2 million bacteria and is increasing at a constant rate of 3.5% every minute. Write a formula for the number of bacteria in the colony after tt minutes.
Answers
The formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]
An exponential growth is in the form:
y = abˣ
where y, x are variables, a is the initial value of y and b > 1
Let y represent the bacteria population after t minutes
Given that initially has 2 million bacteria, hence:
a = 2 million = 2000000
It increases at a rate of 3.5% every minute, hence:
b = 100% + 3.5% = 1.035
The equation is:
[tex]y=2000000(1.035)^t[/tex]
Therefore the formula for the number of bacteria in the colony after t minutes is [tex]y=2000000(1.035)^t[/tex]

Answers
The solution is, New line slope will be -2 and, coordinates (-4. 2).
What is slope?In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line. The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).
here, we have,
Dilation of a line about a point not on the line shifts the line but leaves the slope intact .
New line slope will be -2
As both A and C lie on a horizontal line y = 2, C' will also lie on the same line
The distance between A and C is 0 - 2 = -2
a scale factor of 3 means C' is -2(3) = -6 units left of A
C' = (2 - 6, 2)
= (-4. 2)
Hence, The solution is, New line slope will be -2 and, coordinates (-4. 2).

An angle measures 4.6° less than the measure of its supplementary angle. What is the measure of each angle?
Answers
Answer:
The two angles are,87.7° and 92.3°Step-by-step explanation:
Question,To find an angle and it's supplementary angle.
Let,The supplementary angle be = x
So, the angle given is = x - 4.6
As we know,When two angles added gives 180°, then those angles are called supplementary angles.
Therefore solution,By the problem,
=> x + (x - 4.6) = 180
[On adding like terms x]=> 2x - 4.6 = 180
[Putting - 4.6 to other side of equal to which converts to 4.6]=> 2x = 180 + 4.6 = 184.6
[On dividing 2 on both sides][tex] = > \frac{2x}{2} = \frac{184.6}{2} [/tex]
[On Simplification]=> x = 92.3
Result:So, the supplementary angle is = 92.3° (Ans)(ii)
And, it's required angle is = 180° - 92.3° = 87.7° (Ans)(i)
Supplementary Angles :
If the sum of the measures of two angles is 180°, then the angles are called supplementary angles and each angle is called a supplement of the other.⠀
Given :
An angle measures 4.6° less than the measure of its supplementary angle.⠀
To Find :
The measure of each angle.⠀
Solution :
Let's assume the one of the supplementary angle as "x" and the other angle as (x + 4.6)° .Now,
According to the Question :
[tex]\begin{gathered}\\ \sf x + (x - 4.6) {}^{ \circ} = 180{}^{ \circ} \\ \\ \dashrightarrow \: \sf x + x - 4.6{}^{ \circ} = 180{}^{ \circ} \\ \\ \sf \: \dashrightarrow 2x - 4.6{}^{ \circ} = 180{}^{ \circ} \: \: \: \: \\ \\ \dashrightarrow \sf \: 2x = 180{}^{ \circ} + 4.6{}^{ \circ} \\ \\ \dashrightarrow \sf \: 2x = 184.6{}^{ \circ} \: \: \: \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = \frac{184.6 {}^{ \circ} }{2} \: \: \: \: \: \\ \\ \dashrightarrow \: \sf \: x = 92.3 {}^{ \circ} \: \: \: \: \: \\ \\\end{gathered}[/tex]
Therefore,
One angle = 92.3°Other angle = 180° – 92.3° = 87.7°⠀
Hence,
The measure of the two angles are 92.3° and 87.7° .brainliest and 100 points

Please help! In a tidal river, the time between high and low tide is 5.8 hours. At high tide, the depth of water is 17.2 feet, while at low tide the depth is 4.6 feet. Assume the water depth as a function of time can be expressed by a trigonometric function (sine or cosine).
Write an equation for the depth () of the tide (in feet) hours after 12:00 noon.
Answers
Answer:
Step-by-step explanation:
mean tide is (17.2 + 4.6)/ 2 = 10.9 ft
Amplitude of tide is (17.2 - 4.6)/ 2 = 6.3 ft
The full tide cycle is 2(5.8) = 11.6 hrs
As we are not told the tide condition at 12:00 noon,
I will ASSUME that the tide is high and use the cosine function
D = 10.9 + 6.3cos(2π(t/11.6)) ft
where t is in hours after noon high tide.
make sure your calculator is set to radians.
If you want to use degrees, the equation becomes
D = 10.9 + 6.3cos(360(t/11.6)) ft
