Answer:
∠KNC = 99°
Step-by-step explanation:
∠JNM + ∠KNC = 180 (it is a straight line)
∠KNC = 180 - ∠JNM
∠KNC = 180 - 81
∠KNC = 99°
Answer: 99°
Step-by-step explanation: They are supplementary so 180 - 81 = 99

(-3a 2 b 2)+( –52 a 2 b 2)+ (4a 2 b 2)+(23 a 2 b 2)=
-3a 2 b 2 –52 a 2 b 2 +4a 2 b 2 +23 a 2 b 2=.-28a 2 b 2 is the answer
What is the solution to the equation shown
2/3x + 5= 1
Answer:
x=-6
Step-by-step explanation:
Subtract 5 from 1 So: 2/3x=-4
Multiply 3/2 on both sides : x=-12/2
So x = -6
Answer:
[tex]{x = -6}[/tex]
Step-by-step explanation:
Note: * = times (x)
[tex]\huge {\frac{2}{3} x + 5 = 1}\\[/tex]
Let's isolate the x We can do this via inverse operations.[tex]\frac{2}{3}x + 5 = 1\\-5 \hspace9 \hspace9 -5\\\\\frac{2}{3}x = -4\\ * 3 \hspace9 *3\\\\2x = -12[/tex]
Now that we've isolated the x, we want to simplify it. We do this so we can make x by itself as just x instead of 6x.
[tex]\frac{2x}{2} = \frac{-12}{2} \\\\\frac{2x}{2} = x\\\\\frac{-12}{2} = -6\\\\\huge\boxed {x = -6}[/tex]

The Mayflower started with 150 passengers. It lost 60% due to illness. How many people remained?
Answer:
90 people.
Step-by-step explanation:
60% can be deduced to a fraction of 6/10. If 6/10=150, then you can cross multiply 6*150 and 10*1. 900/10=90.
1. Priya jogs at a constant speed. The relationship between her distance and time is
shown on the graph. Diego bikes at a constant speed twice as fast as Priya.
Sketch a graph showing the relationship between Diego's distance and time.
Answer:
Step-by-step explanation:
Relationship between distance the distance and time for Priya has been given in the graph.
Therefore, slope of the line on the graph will represent the speed of jog of Priya.
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are the points lying on the line.
Since, (0, 0) and (0.4, 2) are lying on the line.
Therefore, slope or speed of the line will be,
Speed = [tex]\frac{2-0}{0.4-0}[/tex]
= 5
Now Diego bikes at a speed twice as fast as Priya,
So Diego's speed = 5×2 = 10 mile per hour
Therefore, slope of the line for Diego on graph will be,
m = 10
Line passing through origin and slope = 10 will be,
y = 10x
Points representing Diego's speed will be,
x 0 0.1 0.2 0.3 0.4 0.5
y 0 1 2 3 4 5
Now we can graph these points to get the line.

A motorboat maintained a constant speed of 16 miles per hour relative to the water in going 55 miles upstream and then retuming. The total time for the tip was 8.0 hours. Use this information to find the speed of the current.
Answer:
6 mphStep-by-step explanation:
Let the speed of the current be c
Time upstream is
55/(16 + c)Time downstream is
55/(16 - c)Total time is 8 hours
55/(16 + c) + 55/(16 - c) = 855(16 -c + 16 + c)/(16 + c)(16 - c) = 855*32= 8*(16² - c²)220 = 256 - c²c² = 36c = 6 mphIs –22 + 9 positive or negative?

the sum of 3 consecutive numbers is 99 what are the numbers
Answer:
32+33+34
Step-by-step explanation:
If I understand the question correctly, you're looking for 3 different numbers that are all consecutive that add up to be 99. The way I did it was finding 3 consecutive numbers that add to 9. 2, 3, 4. I knew the 10s place had to be a 3 because 30+30+30=90, 2+3+4=9, 90+9=99
Find the next term in this
arithmetic sequence.
Answer:
[tex]\bold{-}\frac{\boxed{\bold{11}}}{\boxed{\bold{4}}}[/tex]
Step-by-step explanation:
In arithmetic sequence the terms increase by the same number (d).
So d is the difference between any pair of next and previous term.
[tex]d=-\frac14-1=-1\frac14=-\frac54[/tex]
Therefore the next term will be:
[tex]-\frac32+d=-\frac32+(-\frac54)=-\frac64-\frac54=-\frac{11}4[/tex]

For every 1 litre of water used to make a medicine, 150 ml of sucrose and 600ml of saline solution are used. Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Quantity of water used to make a medicine :-
[tex]= \texttt{1 \: litre }[/tex]
[tex] =\texttt{ 1×1000 \: ml}[/tex]
[tex] =\texttt{\color{hotpink} 1000 \: ml}[/tex]
This quantity of water required to make a medicine = 1000 ml
Quantity of sucrose used to make a medicine = 150 ml
Quanity of saline solution used to make a medicine = 600 ml
The quantity of water to sucrose to saline solution needed to make a medicine as a ratio :-
[tex] = \texttt{1000 : 150 : 600}[/tex]
Cutting each common zero in this ratio, we get :-
[tex] = \texttt{100 : 15 : 60}[/tex]
Dividing each number in the ratio by 5, we get the ratio :-
[tex] =\texttt{ \color{hotpink}20 : 3 : 12}[/tex]
Since, the three numbers in this ratio doesn't have any common factors we can conclude that we have found out the simplest form of the ingredients needed to make the medicine .
Therefore, the ratio of water to sucrose to saline solution needed to make a medicine = 20:3:12

Devaughn is 13 years younger than Sydney. The sum of their ages is 79 . What is Sydney's age?
Answer:
26
Step-by-step explanation:
Let D =Devaughn's age
S= Sydney's age
So D+S=64
D=S+12
Now
D+S=64⇒D=64−S
and so
S+12=64−S 2S=52
S=26
Therefore
D=S+12
D=38

What is f(4) for the function f(x) = 6x +3?
f(4)=0
The value of function f(4) is 27.
It is required to find the value of function f(4).
What is function?
A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.
Given that:
The function is
f(x) = 6x +3
Now put the value x=4 in the given function, we get
f(4)=6(4) +3
= 24+3
=27
f(4)=27.
Hence, the value of function f(4) is 27.
