Answer:
The value of the equation for z is [tex]z=\frac{83}{6-c-t}[/tex].
Step-by-step explanation:
Consider the provided equation.
[tex]-cz+6z=tz+83[/tex]
Subtract tz from both the sides.
[tex]-cz+6z-tz=tz-tz+83[/tex]
[tex]-cz+6z-tz=83[/tex]
Take z common.
[tex]z(-c+6-t)=83[/tex]
[tex]z(6-c-t)=83[/tex]
Divide 6-c-t from both the sides.
[tex]\frac{z(6-c-t)}{6-c-t}=\frac{83}{6-c-t}[/tex]
[tex]z=\frac{83}{6-c-t}[/tex]
Thus, the value of the equation for z is [tex]z=\frac{83}{6-c-t}[/tex].

A tree casts a shadow that is 18 feet in length. If the angle of elevation is 28 degrees, which of the following best represents the height of the tree?
to find the height
multiply the length of shadow by the tangent of the angle
18 * tan(28) =9.5708
the tree is around 9.6 feet tall
The angle of elevation is the angle at which the object is viewed from below. The height of the tree is 8,45feet
Angle of elevationThe angle of elevation is the angle at which the object is viewed from below.
If tree casts a shadow that is 18 feet in length at the angle of 28 degrees, the height is calculated as:
sin theta = opposite/hypotenuse
sin 28 = H/18
H = 18sin28
H = 8.45 feet
Hence the height of the tree is 8,45feet

Match the graph with the correct equation.
y – 5= –(x + 3)
y – 3 = –(x + 5)
y – 3 = (x + 5)
y + 3 = –(x + 5)
Answer: The correct option is (B) [tex]y-3=-(x+5).[/tex]
Step-by-step explanation: We are given to match the graph shown with the correct equation.
From the graph, we note that
(-5, 3) and (0, -2) are two points that lie on the line graph.
So, the slope of the given graph is
[tex]m=\dfrac{-2-3}{0-(-5)}\\\\\\\Rightarrow m=\dfrac{-5}{5}\\\\\Rightarrow m=-1.[/tex]
Since the point (-5, 3) lies on the line, so its equation in point-slope form will be
[tex]y-3=m(x-(-5))\\\\\Rightarrow y-3=-(x+5).[/tex]
Thus, option (B) is CORRECT.

two consecutive even integers have a sum of 346. Find the smailler of these two numbers
Answer:
Smallest number = 172
Step-by-step explanation:
Two consecutive even integers have a sum of 346.
Let x be the smallest number.
We have other number = x + 2
We also have
x + x + 2 = 346
2x + 2 = 346
2 x = 344
x = 172
Smallest number = 172, Other number = 172 + 2 = 174
Smallest number = 172

Bryan is observing the velocity of a cyclist at different times. After four hours, the velocity of the cyclist is 15 km/h. After seven hours, the velocity of the cyclist is 12 km/h.
Part A: Write an equation in two variables in the standard form that can be used to describe the velocity of the cyclist at different times. Show your work and define the variables used. (5 points)
Part B: How can you graph the equations obtained in Part A for the first 12 hours? (5 points)
Part A.
What we can do to solve this problem is to assume that the acceleration of Bryan is constant so that the velocity function is linear. The standard form of a linear function is in the form:
y = m x + b
or in this case:
v = m t + b
where v is velocity and t is time, b is the y –intercept of the equation
The slope m can be calculated by:
m = (v2 – v1) / (t2 – t1)
m = (12 – 15) / (7 – 4)
m = -1
Since slope is negative therefore this means the cyclist are constantly decelerating. The equation then becomes:
v = - t + b
Now finding for b by plugging in any data pair:
15 = - (4) + b
b = 19
So the complete equation is:
v = - t + 19
This means that the initial velocity of the cyclists at t = 0 is 19 km / h.
Part B. What we can do to graph the equation is to calculate for the values of v from t = 0 to 12, then plot all these values in the Cartesian plane then connect the dots.

For Tom
Y = 30 + X
for Nita
Y = 18 + 5X
now solving both equation
30 + X = 18 + 5X

68.32 divided by 2.8
Answer:
24.4
Step-by-step explanation:
We are asked to divide 68.32 by 2.8.
First of all, we will write our given problem as a division problem.
[tex]\frac{68.32}{2.8}[/tex]
We can see that our numerator has two digits after decimal and denominator has one digit after decimal, so we will multiply numerator and denominator by 100 as:
[tex]\frac{68.32\times 100}{2.8\times 100}[/tex]
[tex]\frac{6832}{280}=24.4[/tex]
Therefore, the quotient of our given problem is 24.4.
24.4
Further explanationWe will determine the quotient of 68.32 against 2.8.
Notes:
