Hey there!
I believe the answer to your question is 47.21 ml of oxygen are in the 55 ml sample of sea water.
To get this, you can do 0.8584 x 55 = 47.212, because you want to find 85.84% of 55, to know how much oxygen is in the sample. Then, you round it to the nearest hundreth.
Hope it helps! Have a great day! Do tell me if I'm mistaken.

Solve for x.
I will give brainliest
Answer:
22.5
Step-by-step explanation:
Everything equals 180. This means that the 90 degree angle creates half of that would mean that everything on the right side of the 90 degree angle, also has to equal 90 degrees. X=22.5 because you have to combine like terms meaning x + 3x = 90- 4x=90. Divide by 4 on both sides of the equals sign. Plug that into a calculator and you get 22.5 Since it is only asking for the singular x, you don't have to solve for 3x. (It would be 67.5)
Solve the question below, please
Answer:
x = 133.33°
Step-by-step explanation:
The Law of Cosines
It relates the length of the sides of a triangle with one of its internal angles.
Let a,b, and c be the length of the sides of a given triangle, and x the included angle between sides a and b, then the following relation applies:
[tex]c^2=a^2+b^2-2ab\cos x[/tex]
Since we know the values of all three side lengths, we solve the equation for x:
[tex]\displaystyle \cos x=\frac{a^2+b^2-c^2}{2ab}[/tex]
For the triangle in the figure: a=4.1, b=8.5, c=11.7, x=angle C. Applying the formula:
[tex]\displaystyle \cos x=\frac{4.1^2+8.5^2-11.7^2}{2*4.1*8.5}[/tex]
[tex]\displaystyle \cos x=\frac{-47.83}{69.7}[/tex]
[tex]\displaystyle \cos x=-0.6862[/tex]
[tex]x = \arccos (-0.6862)[/tex]
x = 133.33°

2y + 4x = 16
Anyone know how to solve for Y?
Answer:
y = -2x + 8
Step-by-step explanation:
In this question, you have to solve for "y".
Solve:
2y + 4x = 16
Get "y" by itself by subtracting 4x from both sides.
2y = -4x + 16
Simplify by dividing both sides by 2.
y = -2x + 8

Find the values of x and y.
2x 28 4y 28
Answer:
y=7
x°=15°
Step-by-step explanation:
First we see that there is a equilateral triangle (all angles and also sides should be equal to each other) meaning that 4y=28, which simplifies to y=7
Additionally, we can see that one of the acute angles of the equilateral triange is complementary with the 2x° angle, so 2x°+(the acute angle)=90°
Since the triangle is equilateral each angle must be equivalent and since there is only 180° in a triangle each angle is 180°/3=60°
so 2x°+(60°)=90°
simplify for x°
2x°=30°
x°=15°
An account has a principal of $500 and a
simple interest rate of 3.3%. How much interest
would be earned after 3 years?
Answer:
$49.50
Step-by-step explanation:
Simple interest formula => interest = principal x rate x time period
interest = 500 x .033 x 3 years
interest = 49.50

Given the linear equation Ax+By=8,it's x intercept is (8,0) and y-intercept is (0,8). What are the values of a and b
Answer:
A=1, B=1
Step-by-step explanation:
Equation of the line in intercept form
The intercept form of the equation of a line is:
[tex]\displaystyle \frac{x}{h}+\frac{y}{k}=1[/tex]
Where:
h = x-intercept
k = y-intercept
We are given the y-intercept (0,8) and x-intercept (8,0), thus the equation is:
[tex]\displaystyle \frac{x}{8}+\frac{y}{8}=1[/tex]
Multiplying by 8:
x + y = 8
Thus, the values of A and B are:
A=1, B=1
Which expression is equivalent to |b| > 6 ?
b 6
b 6
b > –6 or b –6 and b < 6
Answer:
number 3. is the correct answer.
Write the equation of the function of a parabola with vertex at (–1,–2) and a point (1,–6) that lies on the curve.
Question 9 options:
f(x) = −(x − 1)2 − 2
f(x) = −(x + 1)2 − 2
f(x) = (x + 1)2 – 2
f(x) = (x − 1)2 − 2
Answer:
The second answer is the correct one, f(x) = -(x + 1)² - 2
Step-by-step explanation:
We know that the answer must either be the second or third, because those two have (x + 1) squared, which means that the vertex must have an x co-ordinate of -1.
We also know that the third one can't be correct, as the y-coordinate of -6 requires a negative coefficient of the x^2. Without that the parabola would be moving upward from its vertex of (-1, -2).
With those we can eliminate all answers but the second one

Answer:
180-118= 62
Answer is angle E= 62
Step-by-step explanation:
Vertical opposite angle of 118 is 118
So, we found out the interior angle. And sum of interior angles is 180. So you subtract 118 from 180 to get angle E.
Hope this helps!!!
Answer:
E is 62
Step-by-step explanation:
First find any angle relationships with the angle 118.
You can see that 118 can go next to E (corresponding angles).
That is a straight line, so in total it will 180 degrees.
180-118 would be E.
180-118 is 62.
hope this helps! :)
