Thus, the most he could weigh that is the upper bound of the given condition is 84kg.
What about weigh?
The word "weigh" is not frequently used by itself in arithmetic. The notion of weight or mass, for example, can be used when measuring or comparing quantities. While mass is a measurement of the quantity of matter inside an object, weight is a measure of the gravitational force acting on it. Weight can be viewed as the force a standard gravitational field applies to an object in the setting of measurement. Weight or mass may be denoted in mathematical equations by variables such as "w" or "m," and the units used to measure them may change based on the situation.
Define upper bound:
In mathematics, an upper bound is a number that is greater than or equal to all the elements in a given set. More formally, let S be a set of real numbers. A number u is an upper bound for S if and only if for all x in S, we have x ≤ u.
For example, consider the set S = {2, 4, 6, 8}. The number 10 is an upper bound for S because 2 ≤ 10, 4 ≤ 10, 6 ≤ 10, and 8 ≤ 10. However, the number 7 is not an upper bound for S because 8 > 7.
Note that an upper bound need not be an element of the set S itself. For instance, the set of all negative real numbers does not have any upper bound among the negative real numbers, but 0 is an upper bound for this set.
It's worth noting that an upper bound may or may not be a member of the set S. If an upper bound is a member of S, then it is called a "maximum" or "greatest" element of S. However, if an upper bound is not a member of S, then S has no maximum element.
According to the given information:

The level of service for the urban freeway is level E, and the density is 61.25 vehicles per mile.
To determine the level of service for the urban freeway, we can use the Highway Capacity Manual (HCM) method, which considers factors such as traffic volume, speed, and density.
Based on the given traffic flow of 2500 vehicles per hour and a design speed of 60 mph, the capacity of the four-lane freeway can be calculated as 8000 vehicles per hour. Using this value, along with the interchange spacing of 0.33 miles, we can determine the density of the freeway, which is 61.25 vehicles per mile.
Using the HCM method, the level of service is determined by comparing the freeway density to the capacity, which results in a level of service of E. Level E indicates that the freeway is operating at or near its capacity, and delays are frequent.
In conclusion, the urban freeway has a level of service classified as E, and density of the freeway, which is the number of vehicles per mile, is calculated to be 61.25.

First, we evaluate the exponent (3/8) using the exponent rules:
[tex](11)^(3/8) = (11^(1/8))^3 = 1.706[/tex]
Next, we substitute this value back into the equation:
[tex]y = e^0.5 x^(3/8)[/tex]
[tex]y = e^0.5 (11)^(3/8)[/tex]
[tex]y = e^0.5 (1.706)[/tex]

Which angles are supplementary to <4 iready
Any angle that shares a common vertex with <4 and whose measure adds up to 180 degrees is supplementary to <4.
To determine which angles are supplementary to <4, we first need to understand the concept of supplementary angles. Supplementary angles are pairs of angles whose sum is 180 degrees. In other words, if we have two angles, and their measures add up to 180 degrees, then they are supplementary to each other.
To find angles that are supplementary to <4, we need to look for other angles that add up to 180 degrees with <4. We can do this by examining the angles that intersect <4 or that share a common vertex with <4.
One way to identify such angles is to draw a diagram of the situation. Suppose we have a line with <4 marked on it. We can then draw another line that intersects the first line at <4, creating two angles on either side of <4. Let's call these angles A and B, where A is adjacent to <4 and B is adjacent to the other side of <4.
If we can find angle A or angle B, we can determine the other angle that is supplementary to <4. We know that A and B add up to 180 degrees, so if we find one of these angles, we can subtract it from 180 degrees to find the other angle.
To summarize, to find angles that are supplementary to <4, we can:
Draw a diagram of the situation, with <4 marked on a line and another line intersecting it at <4.
Identify the adjacent angles on either side of <4.
Label these angles A and B.
Determine the measure of either A or B.
Subtract the measure of the known angle from 180 degrees to find the measure of the other angle.

What is the verbal description of y=2/5x. WHO EVER ANSWERS WILL GET BRAINLIEST!!
The equation describes a linear relationship between two variables, where the output of the equation, y, is equal to two fifths of the input, x.
To calculate the value of y in the equation y=2/5x, we need to start by identifying the value of x. Once that is known, the value of y can be calculated by substituting x into the equation. For example, if x=10, then we can substitute 10 into the equation to get y=2/5 x 10. To solve this, we can multiply 2/5 by 10 to get 2x10/5, which simplifies to 20/5. Since dividing by 5 is the same as multiplying by 1/5, we can simplify this to 20/5 = 4. Therefore, when x=10, y=4.

Find the radian measure of all angles whose cosine is -0.89
(One of the answers is 3.62, but shouldn’t we add pi instead of minus 2pi) (I have a test tomorrow please answer if you know!)
Check the picture below.
so going on the 1st revolution from 0 to 2π, we get those two angles you see in the picture, the cosine is positive on I and IV Quadrants, whilst negative on the II and III Quadrants, so any angles with that negative cosine will be only on those two Quadrants.
when getting an angle or a trig function, make sure your calculator is in the correct mode, because plugging in cos(-0.89) in Degree mode, it's going to assume you mean to find the cosine of -0.89 Degrees, and same will happen the other way around, so make sure your mode is correct, so the input is understood correctly.
the cos⁻¹ function has a range of 0 to π, so any angles it's going to spit out will be on those Quadrants, we get the one in the III Quadrant in the picture by simply using the reference angle from the II Quadrant, the reference angle is about 0.47359 radians, so if we add that to π, we get that many radians.
now, if we want to include All revolutions around the circle, we can say

Rate of change is not a method that can be used to solve a system of equations.
EquationsWhen solving a system of equations, it is important to use a valid method to find the solution. A system of equations is a set of two or more equations with multiple variables that must be solved simultaneously. There are different methods to solve a system of equations, but some methods are more effective than others.
Elimination (Linear Equations) is a method of solving a system of equations by adding or subtracting the equations to eliminate one of the variables. This allows the remaining variable to be solved easily. Substitution is another method where one variable is solved for in one equation and then substituted into another equation to solve for the other variable. Graphing involves plotting the equations on a graph and finding the intersection point(s) of the two lines. This is the solution(s) to the system of equations.
Rate of change, on the other hand, is not a method of solving a system of equations. It refers to the ratio of the change in one variable to the change in another variable. It is a concept used in calculus and differential equations, but it is not a valid method to find solutions to systems of equations. Therefore, when solving a system of equations, it is important to use a valid method to ensure accurate results.

The size of a certain insect population is given by P(t) = 100e^.03t. where t is measured in days. a. How many insects were present initially? b. Give a differential equation satisfied by P(t). c. At what time will the population double?
d. At what time will the population equal 300?
We have that, The size of a given insect population is given by [tex]P(t) = 100e^{.03t}[/tex]. Where t is measured in days, we obtain the following:
a. Initially there were 100 insectsb. The differential equation satisfied by P(t) is: [tex]dP(t)/dt = 3e^{(.03t)}[/tex]c. The population will approximately double in t = 23.10 days.d. The population will equal 300 approximately in t = 36.32 days.a. To find the initial size of the insect population, we need to evaluate P(t) at t=0:
[tex]P(0) = 100e^(.03 * 0)P(0) = 100e^0\\P(0) = 100(1)\\P(0) = 100\\[/tex]
Therefore, initially there were 100 insects.
b. To find the differential equation satisfied by P(t), we need to find the derivative of P(t) with respect to time (t):
[tex]dP(t)/dt = d(100e^{(.03t))}/dt\\dP(t)/dt = 100(.03)e^{(.03t)}[/tex]
Then, the differential equation satisfied by P(t) is:
[tex]dP(t)/dt = 3e^{(.03t)}[/tex]
c. To find the time when the population doubles, we need to find t when P(t) = 200:
[tex]200 = 100e^{(.03t)}\\2 = e^{(.03t)}\\[/tex]
Now, take the natural logarithm (ln) of both sides:
[tex]ln(2) = ln(e^{(.03t)})\\ln(2) = .03t[/tex]
Solve for t:
[tex]t = ln(2)/.03 \approx 23.10.[/tex]
Therefore, the population will approximately double in t = 23.10 days.
d. To find the time when the population equals 300, we must solve for t at P(t) = 300:
[tex]300 = 100e^{(.03t)}\\3 = e^{(.03t)}[/tex]
Take the natural logarithm (ln) of both sides:
[tex]ln(3) = ln(e^{(.03t)})\\ln(3) = .03t[/tex]
Solve for t:
[tex]t = ln(3)/.03 \approx 36.32.[/tex]
Therefore, the population will equal approximately 300 at t = 36.32 days.

Applying the property of the diagonals of a kite, the measure of angle F is calculated as: 71°.
What is the Property of the Diagonals of a Kite?The property of the diagonals of a kite is that they intersect at a right angle, while the shorter diagonal divides it into two isosceles triangles.
Thus, FH is a diagonal that divides the kite into two isosceles triangles, therefore:
m<EFH = 1/2(180 - 142)
m<EFH = 19°
m<GFH = 1/2(180 - 76)
m<GFH = 52°
m<F = m<EFH + m<GFH
m<F = 19 + 52
m<F = 71°

Answer:
m∠F = 71°--------------------------
Property of kites:
Kites have a pair of congruent and pair of different angles.In the given kite we can see a pair of different angles, ∠G and ∠E.
It means the other two angles are congruent:
∠F ≅ ∠HWe know the sum of interior angles of a quadrilateral is 360°.
Find the missing angle measure:
m∠E + m∠F + m∠G + m∠H = 360142 + m∠F + 76 + m∠F = 3602* m∠F + 218 = 3602*m∠F = 142 m∠F = 71°
