This is the same triangle you used for Question 2. Triangle ABC has angle measures as shown below. Using the information in the diagram, and the value of x that you calculated i Question 2, find the measure of Angle C. In your answer, give the measure of Angle C and explain how you calculated it.
Answer:
93
Step-by-step explanation:
So, you know the angles of a triangle added together is 180.
180-52-35=93

Answer: 15.5 degree
Step-by-step explanation:
You make a shade of green icing using 2 drops of yellow food coloring for every 4 drops of blue. How many drops of blue food coloring would you need if you use 4 drops of yellow food coloring? how many drops of blue food coloring would u need if you use 4 drops of yellow food coloring
Answer:
8 drops of blue
Step-by-step explanation:
You doubled the yellow from 2 drops to four
so double the blue from 4 to 8
In the figure below, L is parallel to M. Find X
Answer:
Let's first try to find the angle supplementary to measure 141°.
(Supplementary angles are two angles that add up together to equal 180°).
Set up an equation;
141 + x(unknown angle measure) = 180°
Solve for x:-
141 + x = 180
-141 -141
x = 39°.
Now that we've found one of the interior angles measure to this triangle, we will use this value to figure out the angle measure next to 'x'.
If we think of the line (highlighted in the picture I attached to this), extended, we can kind of make out of this line as a transversal cutting into the two parallel lines(L & M).
Furthermore, the measured angle 39°, is an alternate interior angle with the missing angle next to 'x'(highlighted with yellow in my picture).
And, alternate interior angles are congruent(meaning they measure the same degree).
Therefore, we can infer that the missing angle next to 'x' is also 39°.
Now that we've found one angle measure and another angle(given) next to x, we can see that angle x and those two angle measures (48° and 39°) combined are supplementary!
So now that we know that angles 48° and 39° are supplementary with x, we can find the value of x by finding it's supplement value!
Arrange an equation;
(48 + 39) + x = 180°
Simplify and solve for x:-
87 + x = 180
-87 -87
x = 93°, hence ∠X = 93°.
Solve for the value of k.
(k+1)°
42°
simplify 15a+21b-6a-4
Answer:
9a+21b-4
Step-by-step explanation:
first of all combine the like terms
15a + 21b - 6a - 4
= 9a + 21b - 4 Ans.
The simplified expression of 15a+21b-6a-4 is 9a+21b-4
What is Expression?An expression is combination of variables, numbers and operators.
The given expression is 15a+21b-6a-4
Fifteen times of a plus twenty one times of b minus six times of a minus four.
a and b are the variables and plus, minus are the operators
Add the like terms in the expression
15a-6a+21b-4
Fifteen times of a and minus six times of a are the like terms.
So add these like terms.
When 15 and -6 are added we get 9
So the expression becomes as Nine times of a plus twenty one times of b minus four.
9a+21b-4
Hence, the simplified expression of 15a+21b-6a-4 is 9a+21b-4

The perimeter of the rectangle below is 222 units find the length of side RS
Answer:
111
Step-by-step explanation:
divide 222 by 2 and you get your answer
Answer:
55.5
Step-by-step explanation:
since we don't know the length or width of any side, one length side will only be 1/4 of 222. And perimeter is all the sides added up. This rectangle will actually be a square.
222/4=55.5

A lawyer charges a $75 consultation fee and then $120 per hour thereafter.
a). Identify the dependent and independent variable.
b). Make a table of values for the cost of $C of an appointment with the lawyer for time t hours where t= 0,1,2,3,4.
c). What is the relationship between C and t linear?
d). If you graphed this relationship, is it sensible to join the points graphed with a straight line? Give reason with your answer.
e). For every increase of 1 hour for t, what is the change in C?
f). For an appointment with the lawyer, what is the fixed cost and variable cost?
Answer:
(a) The dependant veriable is the $120 per hour and the independant veriable is the $75 consultaion fee.
(b) The table of vaules for this would look like this, [tex]\frac{C}{T} \frac{75}{0} \frac{195}{1} \frac{315}{2} \frac{435}{3} \frac{555}{4}[/tex], where C = cost and T = time.
(c) The relationship between C and T is linear, beacause with the more hours you take the cost increases.
(d) Yes, it is sensible because the points would be in line due to the steady increase of the hourly rate.
(e) For every hour spent the cost increases 120 dollars.
(f) The fixed cost is 75 dollars for consultation and the veriable cost is 120 per hour.

[tex]17113 = \frac{300k}{ {0.09}^{2} } [/tex]
[tex]k = 0.462[/tex]
