Find the height of this rectangle (urgent! it's due by tonight!)
Answers
Answer:
H=1/2
Step-by-step explanation:
the area of a rectangle is given by A=L*H
L is already given, L= 5/3
A is given, A=5/6
therefore: 5/6 = (5/3)*H
H=(5/6) * (3/5) = 1/2
Answer: \(\displaystyle \frac{1}{2}\) ft
Step-by-step explanation:
We are given the length and the area;
A = L * W
We will plug in the values given, and solve for the unknown.
A = L * W
\(\frac{5}{6}\) = \(\frac{5}{3}\) * ?
\(\displaystyle \frac{\frac{5}{6}}{\frac{5}{3} } =?\)
\(\displaystyle \frac{5}{6}\) * \(\displaystyle \frac{3}{5}\) = ?
\(\displaystyle \frac{5*3}{6*5}\) = ?
\(\displaystyle \frac{15}{30}\) = ?
\(\displaystyle \frac{1}{2}\) = ?
The height is \(\displaystyle \frac{1}{2}\) ft.
Identify the number line that correctly displays the solution x ≥ 3.
Answers
The correct number line that displays the solution `x ≥ 3` would be:
<------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------|------>
-10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1 2 3 4 5 6 7 8 9 10
●------------------------------------------------>
The solution `x ≥ 3` is an inequality that means x is greater than or equal to 3. To graph this inequality on the number line, we mark the point representing the value 3 with a closed circle on the number line and draw an arrow pointing to the right to indicate that all values greater than or equal to 3 satisfy the inequality.
The closed circle at 3 indicates that 3 is included in the solution set, and the arrow to the right indicates that all values greater than 3 also satisfy the inequality. Therefore, any value of x that is equal to or greater than 3 would be considered a solution to the inequality `x ≥ 3`.
It is important to note that if the inequality was `x > 3` (without the equal sign), the closed circle at 3 would be changed to an open circle, indicating that 3 is not included in the solution set, and only values greater than 3 would be considered solutions. In conclusion, the number line provided above correctly displays the solution `x ≥ 3`.

Find the standard form of the equation of the line through (8,-3) that is parallel to the line 3y=4x+8
Answers
The standard form of the equation of the line passing through (8,-3) that is parallel to the line 3y=4x+8 is 4x - 3y = 41
How to represent equation in standard form?The equation of the line in standard form can be represented as follows:
Ax + By = C
where
A, B and C are constantTherefore, the standard form of the equation of the line through (8,-3) that is parallel to the line 3y = 4x + 8 is a s follows;
Parallel lines have the same slope.
Hence,
3y = 4x + 8
y = 4 / 3 x + 8 / 3
The slope of the line is 4 / 3. Hence, the line passes through (8, -3). let's find the y-intercept.
y = 4 / 3 x + b
-3 = 4 / 3 (8) + b
b = -3 - 32 / 3
b = -9 - 32/ 3
b = -41 / 3
Hence,
y = 4 / 3 x - 41 / 3
multiply through by 3
3y = 4x - 41
Therefore, the standard form is 4x - 3y = 41

Answers
The solution is ,if it takes three people 4 hours to clean a warehouse , then 3 hours will it take 4 people to clean the warehouse.
Here, we have,
given that.
if it takes three people 4 hours to clean a warehouse
now, we have to find that how long will it take 4 people to clean the warehouse.
i.e. we have,
3 people take to clean = 4 hours
let, 4 people will take to do it x hours.
now, we have,
3 people take to clean = 4 hours
so, 1 people take to clean = 4*3 hours
so, 4 people take to clean = 4*3 / 4 hours
i.e. we get,
x = 4*3 / 4 hours

A soccer ball travels upward from a height of 11 feet with an initial velocity of 20
feet per second. The quadratic function h (t) = -16t² + 20t+11 models the height
of the ball, where h (t) is the height, in feet, of the soccer ball and t is the time that
ball has been in the air, in seconds. When is the soccer ball above 15 feet?
A. The soccer ball is above 15 feet between 0 seconds and 0.5 second.
B. The soccer ball is above 15 feet between 0.5 second and 1 second.
C. The soccer ball is above 15 feet between 0:25 second and 1
second.
D. The soccer ball is above 15 feet between 0 seconds and 0.25 second.
Answers
The soccer ball is above 15 feet between 0.25 seconds and 1 second.
To determine when the soccer ball is above 15 feet, we need to find the values of t that satisfy the inequality h(t) > 15.
Given the quadratic function h(t) = -16t² + 20t + 11, we can rewrite the inequality as follows:
-16t² + 20t + 11 > 15
Subtracting 15 from both sides:
-16t² + 20t - 4 > 0
Simplifying further:
-16t² + 20t - 4 = -4(4t² - 5t + 1) = -4(t - 1)(4t - 1) > 0
Now, we can solve for t by finding the values that make the inequality true. We have two factors: (t - 1) and (4t - 1).
Setting each factor greater than zero and solving for t:
t - 1 > 0 => t > 1
4t - 1 > 0 => 4t > 1 => t > 1/4
So, we have t > 1 and t > 1/4. To satisfy both conditions, t must be greater than the maximum of 1 and 1/4, which is 1.
Therefore, the soccer ball is above 15 feet for t > 1 second.
The correct answer is:
C. The soccer ball is above 15 feet between 0.25 seconds and 1 second.

Suppose that the world's current oil reserves is R= 1830 billion barrels. If, on average, the total reserves is decreasing by 20 billion barrels of oil each year, answer the following:
Answers
We have the following information;
The world's current oil reserves is R= 1830 billion barrels and is decreasing by 20 billion barrels of oil a year.
a. We want to give an equation for the remaining barrels R in terms of time t.
The equation is ;
\(R=1830-20t\text{ Where R is in billions of barrels}\)b. 8 years from now, the world's oil reserve would be;

Answers
Answer:
0.0625 mL/hr.
Step-by-step explanation:
To calculate the flow rate in mL/hr, we need to know the total volume of the solution, the concentration of the solution, and the desired infusion rate.
Given:
Volume: 500 mL
Concentration: 0.45% (or 0.0045 g/mL)
Infusion rate: 500 units/hr
We know that:
Infusion rate = Volume x Concentration / Time
We can rearrange the formula to solve for time:
Time = Volume x Concentration / Infusion rate
Now we can plug in the given values:
Time = 500 mL x 0.0045 g/mL / 500 units/hr
To convert the time to hours, we will divide the time by 3600 seconds/hour
Time = 500 mL x 0.0045 g/mL / 500 units/hr / (1 hr/3600 s)
Now we have the flow rate in mL/hr
Time = 0.0625 mL/hr
So the flow rate should be set at 0.0625 mL/hr.
It's important to note that the heparin added is 25000 U, this is not related to the flow rate calculation.

Solve the system of equation algebraically y =
x ^ 2 + 4x + 3 y = 2x + 6
Answers
y = x ^ 2 + 4x + 3 --- Equation 1
y = 2x + 6 --- Equation 2
We can set the right-hand sides of the two equations equal to each other since they are both equal to y:
x ^ 2 + 4x + 3 = 2x + 6
Subtracting 2x + 6 from both sides, we get:
x ^ 2 + 2x - 3 = 0
We can factor the quadratic equation:
(x + 3)(x - 1) = 0
This gives us two possible solutions:
x + 3 = 0 or x - 1 = 0
Solving for x, we get:
x = -3 or x = 1
Substituting these values back into either Equation 1 or Equation 2, we can solve for y:
When x = -3, y = (-3) ^ 2 + 4(-3) + 3 = 0
When x = 1, y = 2(1) + 6 = 8
Therefore, the solution to the system of equations is (x, y) = (-3, 0) and (1, 8).

The shape of the distribution of the time to get an oil change is 15 minute oil change factory is unknown. However records indicate that the mean time is 16.9 and the standard deviation is 4.7 minutes Suppose the manager agrees to pay each employee a $50 bonus if they meet a certain goal. On a typical
Saturday, the oil-change facility will perform 40 oil changes between 10 A.M. and 12 P.M. Treating this as a random
sample, at what mean oil-change time would there be a 10% chance of being at or below? This will be the goal
established by the manager.
There would be a 10% chance of being at or below minutes.
(Round to one decimal place as needed.)
Answers
The mean oil-change time for which there is a 10% chance of being at or below is approximately 15.92 minutes.
What is the mean oil-change time?We can start by using the Central Limit Theorem.
Data given:
The population mean is μ = 16.9 minutes
population standard deviation is σ = 4.7 minutes
sample size of n = 40 oil changes performed between 10 A.M. and 12 P.M.
The standard error of the mean (SE) is given by:
SE = σ / √n
SE = 4.7 / √40
SE = 0.743
To find the mean oil-change time for which there is a 10% chance of being at or below, we need to find the z-score associated with the 10th percentile of the standard normal distribution, which is -1.28 (using a standard normal distribution table or calculator).
We can use the formula for a z-score:
z = (x - μ) / SE
where x is the desired mean oil-change time.
Substituting the known values and solving for x, we get:
-1.28 = (x - 16.9) / 0.743
x = -1.28 * 0.743 + 16.9
x = 15.92

A z-test for single proportion would to used to perform the test.
Compute the value of the test statistic as follows:
