A restaurant used 231 eggs last week. 46 of them are colored white, w. The remaining eggs are colored brown. Write an equation that represents the situation. ( i will give you brainly)
Answer:
46 + W = 231
Step-by-step explanation:
Answer:
My guess: 231 = 46 + b
Step-by-step explanation: Because they didn't mention how many were colored brown, we would use a variable to represent them, in this case I use b. But we do know 46 of them were white. so the equation would simply be 231 = 46 + b. After you add 46 and b you will get the total to 231. You can find b from subtracting 231 to 46. Then add b to 46 and get the total of 231
Find the value of x in the picture below. (round to nearest tenth if needed) THANK YOU FOR HELPING ME:)
Answer:
x ≈ 9.6
Step-by-step explanation:
Using Pythagoras' identity in the right triangle, that is
x² + 14² = 17²
x² + 196 = 289 ( subtract 196 from both sides )
x² = 93 ( take the square root of both sides )
x = [tex]\sqrt{93}[/tex] ≈ 9.6 (to the nearest tenth )
consider the following function and express the relationship between a small change in x and the corresponding change in y in the from dy = f^1 (x) dx.
f(x) = 2x^3-4x
dy= dx
For a small change in x (dx), the corresponding change in y (dy) is given by the equation dy = (6x² - 4)dx.
To find the relationship between a small change in x (dx) and the corresponding change in y (dy) for the function f(x) = 2x³ - 4x, we can differentiate the function with respect to x.
f(x) = 2x³ - 4x
Differentiating both sides with respect to x:
f'(x) = d/dx (2x³ - 4x)
f'(x) = 6x² - 4
Now, we can express the relationship between dx and dy in the form of dy = f'(x)dx:
dy = (6x² - 4)dx
Therefore, for a small change in x (dx), the corresponding change in y (dy) is given by the equation dy = (6x² - 4)dx.

Step-by-step explanation:
The altitude perpendicular to the hypotenuse of a right triangle is 12 cm. Express the length of the hypotenuse as a function of the perimeter.
Let's denote the lengths of the legs of the right triangle as a and b, and the length of the hypotenuse as c. We are given that the altitude perpendicular to the hypotenuse is 12 cm.
Using the Pythagorean theorem, we have:
[tex]a^2 + b^2 = c^2[/tex]
The perimeter of the right triangle is given by:
Perimeter = a + b + c
We want to express the length of the hypotenuse (c) as a function of the perimeter.
Rearranging the equation for the perimeter, we have:
c = Perimeter - (a + b)
Substituting the equation for c into the Pythagorean theorem equation, we get:
[tex]a^2 + b^2[/tex] = (Perimeter - [tex](a + b))^2[/tex]
Expanding and simplifying, we have:
[tex]a^2 + b^2[/tex]= [tex]Perimeter^2[/tex] - 2Perimeter(a + b) +[tex](a + b)^2[/tex]
Simplifying further:
[tex]a^2 + b^2[/tex]= [tex]Perimeter^2[/tex]- 2Perimeter(a + b) + a^2 + 2ab + b^2
The terms with [tex]a^2[/tex] and [tex]b^2[/tex]cancel out, giving:
[tex]2ab = Perimeter^2 - 2Perimeter(a + b)[/tex]
Dividing both sides by 2, we have:
[tex]ab = (Perimeter^2 - 2Perimeter(a + b))/2[/tex]
[tex]ab = (Perimeter^2 - 2Perimeter(a + b))/2[/tex]
Now, since we are given that the altitude perpendicular to the hypotenuse is 12 cm, we know that:
ab = [tex]12^2 = 144[/tex]
We can solve this equation for either a or b, and then substitute the value into the expression for the hypotenuse (c):
For example, let's solve for a:
a = 144/b
Substituting this into the expression for c
c = Perimeter - (a + b)
c = Perimeter - (144/b + b)
Therefore, the length of the hypotenuse (c) can be expressed as a function of the perimeter.

Check for a significant change over first-time composite scores when a group of 30 high school seniors retake the Miller Analogies Test (MAT) after completing a Test Preparation Workshop; note that each student will have taken the MAT twice, once before and once following the workshop, and the scores are on a ratio scale.
The preparation workshop’s impact on first-time composite scores can be assessed by evaluating the scores of a group of 30 high school seniors who retake the Miller Analogies Test (MAT) after attending the workshop.
The MAT is taken twice by each student: once before the workshop and once after it. The scores are reported on a ratio scale.
To check if there has been a significant change in scores, the following steps can be followed:
Step 1: To determine the change in scores, subtract the scores obtained before the workshop from the scores obtained after the workshop.
Step 2: Calculate the average score change for the group of 30 students by dividing the sum of score changes by 30.
Step 3: Calculate the standard deviation of the score change by using the following formula:
SD = √[∑ (Xi - X)2 / (n - 1)]
where Xi is the individual score change, X is the average score change, and n is the number of students.
Step 4: Use a t-test to determine if the change in scores is statistically significant. If the t-value is greater than the critical value (using a 5% significance level and 29 degrees of freedom), then the change in scores is significant.
Thus, by following these steps, the impact of the preparation workshop on first-time composite scores of the MAT can be assessed.

(1 point) Find the square root of 8-2i so that the real part of your answer is positive. The square root is
The square root of 8 - 2i, with the real part of the answer being positive, is approximately 2.34 + 0.52i.
To find the square root of 8 - 2i, we can represent the complex number in its polar form and then apply the square root operation.
First, we calculate the magnitude (r) and argument (θ) of the complex number 8 - 2i:
Magnitude: |8 - 2i| = √([tex]8^2[/tex] + (-2[tex])^2[/tex]) = √(64 + 4) = √68 = 2√17
Argument: θ = arctan(-2/8) = arctan(-1/4) ≈ -0.24498 radians
Next, we express the complex number in polar form:
8 - 2i = 2√17 * (cos(-0.24498) + isin(-0.24498))
To find the square root, we take the square root of the magnitude and divide the argument by 2:
√(8 - 2i) ≈ √(2√17) * (cos(-0.24498/2) + isin(-0.24498/2))
Simplifying the expression:
√(8 - 2i) ≈ √(2√17) * (cos(-0.12249) + isin(-0.12249))
≈ 2.34 + 0.52i
Therefore, the square root of 8 - 2i, with the real part of the answer being positive, is approximately 2.34 + 0.52i.

The measures of two complementary angles are in the ratio of 2 : 7. Find the measurements of the two angles.
Answer: 20° & 70°
Step-by-step explanation:
We know complementary angles will add up to 90° and we also know we can divide the total by 9 parts because our ratio is 2 parts to every 7 parts.
To find each individual part size...
9x=90
x=10
so use our ratio...
2x10=20 for first angle
7x10=70 for second angle
It is important to understand that integral equations also arise from problems in differential equations. (a) For example, write the initial value problem dx = f(t, x), x(to) = xo dt as an integral equation and indicate what kind of equation it is. (b) Show that an initial value problem d²x dt² = f(t, x), x(to) = xo, x'(to) = x₁ involving a second order differential equation can be transformed into a Volterra integral equation
The Volterra integral equation:
x(t) - xo = ∫[to, t] y(s) ds
y(t) - x₁ = ∫[to, t] f(s, x(s)) ds
(a) To write the initial value problem dx = f(t, x), x(to) = xo dt as an integral equation, we can use the integral representation of the solution.
Let's consider the integral equation:
x(t) = xo + ∫[to, t] f(s, x(s)) ds
This integral equation is of the Volterra type, as it involves a definite integral and depends on the function x(s) evaluated over the interval [to, t].
(b) To transform the second-order initial value problem d²x/dt² = f(t, x), x(to) = xo, x'(to) = x₁ into a Volterra integral equation, we can introduce a new variable, y(t), defined as the derivative of x(t):
y(t) = dx/dt
Now, we can rewrite the second-order differential equation as a system of first-order differential equations:
dx/dt = y(t)
dy/dt = f(t, x)
To represent this system as an integral equation, we'll integrate both equations from to to t.
This yields:
x(t) - xo = ∫[to, t] y(s) ds
y(t) - x₁ = ∫[to, t] f(s, x(s)) ds
Combining these two equations, we obtain the Volterra integral equation:
x(t) - xo = ∫[to, t] y(s) ds
y(t) - x₁ = ∫[to, t] f(s, x(s)) ds
This integral equation is also of the Volterra type, involving definite integrals and depending on the functions x(s) and y(s) evaluated over the interval [to, t].

SOCCER PRACTICE BEGAN AT 2:30 P.M 3:30 P.M THROUGH WHAT FRACTION OF A CIRCLE DID THE MINUTE HAND TURN HOW MANY DEGREES DID THE MINUTE HAND TURN
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°
