Answer:

The time Jacob spent on the test represented by J = (m + 10) minutes

where m is the number of minutes spent by Mark on the test

Step-by-step explanation:

Here, we want to give an equation which represents the time taken for Jacob to finish his test compared to the time m which Mark spent on the test.

Since Jacob finished 10 minutes before Mark, it means Mark actually took longer on the test.

Now, we are told that Mark spent m minutes on the test, the time spent by Jacob on the test is thus (m + 10) minutes

Let the amount of time spent by Jacob be J minutes. This in relation to the amount of time spent by Mark will be ;

J = (m + 10) minutes

4. Jason and Allison are hiking in the woods when they spot a rare owl in a tree. Jason stops and measures an angle of elevation
fenix001 [56]

Here is the correct format for the question.

Jason and Allison are hiking in the woods when they spot a rare owl in a tree. Jason stops and measures an angle of elevation of 22° 8’ 6”. At the same time, Allison is standing 48 feet closer to the tree, measuring an angle of elevation of 30° 40’ 30” to the owl. If Jason and Allison are the same height, their eyes 5 feet from the ground, find the height of owl in the tree.

Answer:

The height of the owl from the ground is: 67.1337  ft

Step-by-step explanation:

The first step we are meant to start with is by convert our angle of elevation into degree;

So; we have the given data

22° 8’ 6”

30° 40’ 30”

To degrees ; we get :

22^o\, 8' \,6" = 22 +\frac{8}{60} +\frac{6}{3600}=22.135^o\\ \\ 30^o\, 40' \,30" = 30 +\frac{40}{60} +\frac{30}{3600}=30.675^o

From the attached file below; we can see a diagrammatic representation of the two right angle triangles together showing the data set which include the position of the hikers , the owl on the tree and the angle of elevations.

The trigonometric equations derived from the right angled triangle can be illustrated as:

tan(22.135^o)=\frac{T}{48+x}  \\ \\tan(30.675^o)=\frac{T}{x}

From above equation ;

solving for the value of T , then equating both equations to determine the value of x to find the  the height of the owl in the tree; we have:

T=(48+x)\,tan(22.135^o)\\ \\T=x\,\,tan(30.675^o)\\ \\(48+x)\,tan(22.135^o)=x\,\,tan(30.675^o)\\ \\ 48\,tan(22.135^o)+x\,\,tan(22.135^o)=x\,\,tan(30.675^o)\\ \\ 48\,tan(22.135^o)=x\,\,(tan(30.675^o)-tan(22.135^o))\\ \\ x=\frac{48\,tan(22.135^o)}{tan(30.675^o)-tan(22.135^o)}  \\ \\x=104.75\,\,ft

However; to find T; we have:

T-x\,\,tan(30.675^o)\\ \\ T=(104.75\,ft)\,\,tan(30.675^o)\\ \\ T=62.1337\,\,ft

From the question; if we take an integral look and an in depth understanding of the question; we will realize that  the value of T = 62.1337 ft is the height the owl is relative to the eye level of the hikers; so if we want to determine  the height of the owl from the ground, there is need to add the given (5 feet from the ground)  to this number:

SO;

The height of the owl from the ground is:  (62.1337 + 5) ft

= 67.1337  ft

A production system has a total daily output of 400 units and a total labor of 350 hours, what kind of productivity measure can
fomenos

Answer:

1.14 products per hour of labor

Step-by-step explanation:

To calculate the daily productivity would be the amount of products per hour of labor.

That is: 400 products / 350 hours of labor, and that is approximately 1.14 products per hour of labor.

Which means that for every hour of labor, 1.14 products are produced in one day, which would be a factor of productivity.

(03.06 MC)Solve the equation for the letter r: d = rt
Neporo4naja [7]
The equation for r: d = rt would be 'r equals d over t.'

How, you might ask? Well, let's consider this example:

You might already know what d = rt stands for... "Distance equals rate times time", so if you divide the two sides by 't', you would come up with r = d/t. So that would finalize as your answer for this question.
