Step-by-step explanation:
The way I learned it was to use "Keep, Change, Flip" (or KCF). It is basically "Keep" the first number (-2/3), "Flip" the sign (division symbol), and Flip the second fraction (-1/2) (switch the numerator and denominator). Then you multiply what is left, simplify, and you are done! I hope this helped.

In a triangle with vertices A,B and C, if C =64° and the lengths AC= 40mm and BC= 70mm find the length AB using cosine rule
Answer:
63.6mm
Step-by-step explanation:
According to cosine rule;
AB² = BC²+AC²-2(BC)(AC)cos m<C
Substitute the given values
AB² = 70²+40²-2(70)(40)cos 64
AB² = 4900+1600-5600cos64
AB² = 6500-5600(0.4384)
AB² = 6500-2,454.87
AB² = 4,045.12
AB = √4,045.12
AB = 63.6mm
Hence the length of AB is 63.6mm

PLS,PLS,PLS,PLS HELP ME THIS QUESTION IS WORTH 10 POINTS. Which number sequence follows the rule add 4 starting from 2?
Answer:
Arithmetic sequence
Step-by-step explanation:
In an arithmetic sequence, the next term on the sequence is obtained by adding a certain value to the first term. This term that is added is uniform throughout the sequence. Once this term is added to the preceding term, the next term of the sequence is obtained. This term that is thus added is known as the common difference of the arithmetic sequence.
So the arithmetic sequence obtained by adding 4 starting from 2 is; 2, 6, 10, 14 .........

A parallelogram has an area of 364.5 cm2. If the base is 27 cm, what is the height? What is the perimeter?
Answer:
Height = 13.5 cm
Perimeter = 81 cm
Step-by-step explanation:
The Area of a parallelogram is given as the product of the base and its height.
A = base * height
Area, A = 364.5 cm²
Base, b = 27cm
Height, h =?
Hence,
364.5 cm² = 27cm * h
h = 364.5 cm² / 27cm
h = 13.5 cm
Perimeter of parallelogram :
P = 2(a + b)
a = height of sides ; b = base
P = 2(13.5cm + 27cm)
P = 2(40.5)
P = 81 cm

Faith wants to run at least 7 miles this week. She has already run 212 miles. She plans to run an equal distance on each of the last 3 days of this week.
Answer:
at least 71 miles each day
Step-by-step explanation:
212 divided by is 70.6
so u can round up to 71.
The required number of miles she will run is 2 miles each day or 1 mile each day.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Celia had 30 minutes to do a three-problem quiz. She spent 9 3/4 minutes on question A and 6 1/2 minutes on question B. How much time did she have left for question C?
Answer:
She has 13 and [tex]\frac{3}{4}[/tex] or 13.75 mins left for question c.
Step-by-step explanation:
first convert both fractions into an improper fraction to make it easier:
[tex]9\frac{3}{4} = \frac{39}{4}[/tex]
[tex]6\frac{1}{2} = \frac{13}{2}[/tex]
add both fractions, make sure both denominators are the same:
[tex]\frac{13}{2}[/tex] x 2 = [tex]\frac{26}{4}[/tex]
[tex]\frac{39}{4} + \frac{26}{4} = \frac{65}{4}[/tex]
convert back to a mixed fraction:
[tex]\frac{65}{4} =[/tex] [tex]16\frac{1}{4}[/tex]
subtract the answer from 30:
[tex]30 - 16\frac{1}{4} = 13\frac{3}{4}[/tex]
Celia has 55/4 minutes to do question C.
What is an improper fraction?A fraction is deemed improper if the numerator is more than or equal to the denominator.
Given, Celia had 30 minutes to do a three-problem quiz.
She spent 9 3/4 minutes on question A and 6 1/2 minutes on question B.
In order to solve the problem:
First, we convert mixed fraction to improper fraction.
That means, [tex]9\frac{3}{4}[/tex] = 39 /4 and [tex]6\frac{1}{2}[/tex] = 13/2
Now, the total time to do the quiz is 30 minutes.
That means,
time for question A + time for question B + time for question C = 30 minutes.
39/4 + 13/2 + time for question C = 30
time for question C = 30 - 39/4 - 13/2
time for question C = 55/4 minutes.
Therefore, She has left 55/4 minutes.

The diagram shows two campsites on opposite ends of a lake and two triangles formed by intersecting segments from the campsites.
Campsites F and G are on opposite sides of a lake. A survey crew made the measurements shown on the diagram. What is the distance between the two campsites? The diagram is not drawn to scale. The triangles are proportional.
Answer:
x=42.3m
Step-by-step explanation:
x/47=82.8/92
92x=3891.6= 42.3m is the distance
Given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.
What are Similar Triangles?Triangles that are similar to each other always have the same shape but different sizes, and the ratio of their corresponding sides are equal (proportional).
The two triangles formed are similar triangles. Therefore:
47/FG = 82/73.8
Cross multiply
FG = (47 × 73.8)/82
FG = 42.3 m
Therefore, given that the triangles formed are similar, the distance between the two campsites is: 42.3 m.

Two people paddle a canoe in a river flowing at a rate of 3 miles per hour, then they returned traveling upstream. The entire trip was 96 miles and the trip upstream took twice as long as the trip downstream. How fast did they row in still water? How many hours was the complete trip?
Answer:
72
Step-by-step explanation:
Answer:
speed in still water = 9 mph
total time = 12 hours
Step-by-step explanation:
speed = distance/time
distance = speed * time
Traveling downstream:
speed of river = 3 mph
speed of canoe in still water = v
speed of canoe going downstream = v + 3
distance = 96/2 = 48
time = t
distance = speed * time
48 = (v + 3)(t)
Traveling upstream:
speed of river = 3 mph
speed of canoe in still water = v
speed of canoe going downstream = v - 3
distance = 96/2 = 48
time = 2t
distance = speed * time
48 - d = (v - 3)(2t)
48 = (v + 3)(t)
48 = (v - 3)(2t)
vt + 3t = 48
2vt - 6t = 48
-2vt - 6t = -96
(+) 2vt - 6t = 48
------------------------
-12t = -48
t = 4
vt + 3t = 48
4v + 3(4) = 48
4v + 12 = 48
4v = 36
v = 9
speed in still water = v = 9 mph
total time = t + 2t = 3t = 3(4) = 12 hours
