Convert both fractions into top heavy fractions:

2 4/6 becomes 16/6
2 x 6 + 4 over 6

1 3/7 becomes 10/7
1 x 7 + 3 over 7

Next use KCF - Keep the first fraction the same, Change the sign to ´x’ and Flip the second fraction:

16/6 x 7/10

Finally multiply the numerators and denominators

16 x 7 = 112
6 x 10 = 60

112/60

Simplify:

112/60 = 56/30 = 28/15

Answers

6a If 17.5% of the students were 7, then 100% would be 100/17.5 times 7 which equals 40.
Therefore, there are 40 students in total.


6b. The amount of students present would be the amount absent taken away from the amount of the students in the class, which is. 40 - 7 = 33. So 33 students were present.

7. If the hat cost $18 dollars in the 10% sale, the percentage is now 90% of the original price (100-10=90). Therefore, if $18 equals 90%, then 100% (the original price) would be 100/90 times 18 which equals 20. So the original price is $20.

8. Apply the same principle as question 7. 76kg is 95% so his original weight is 100/95 times 76 which equals 80kg. Therefore his weight before the decrease is 80kg.

9. Apply the same principle as question 7 and 8. 185l is 88% so the amount of water before evaporating would be 100/88 times 185 which equals 210.22l. Therefore 210.22l would be left.

find the area of the triangles first:
formula for the area of a triangle is A=bh/2
the base is 12
the height can be found by taking the 13(given) subtracting 5(given) and dividing by 2 which gives you 4 and then just fill in the formula
A= 12•4/2
A=24 then multiply by 2(bc there are two triangles and you get
A=48

now to the area of the rectangle which is just
A=BH you fill it in
A=12•5 solve
A=60
then you add the area of the triangles to the area of the rectangle to get the area of the hexagon
A=48+60
A=108

5 The area of a trapezium is 54 cm^2. The length of one of the parallel sides is 8 cm and the height is 6 cm. Find the length of the other parallel side.​

Answers

Answer:

come here if you want to see

The length of the other parallel side is 10 cm.

Trapezium is a quadrilateral (has four sides and four angles) with a pair of parallel sides. The area (A) of a trapezium is given by:

A = (1/2)(a + b)h

where a and b are the length of the parallel sides, h is the height of the trapezium

Given A = 54, a = 8 cm, h = 6 cm, hence:

54 = (1/2)(8 + b)6

8 + b = 18

b = 10 cm

The length of the other parallel side is 10 cm.

2. Do you know how fast last year's winner was traveling? (2 points)
3. What information do you need to know to calculate last year's winning speed? Remember, the distance traveled (length of the course) is equal to the rate (boat's speed) times the time. (2 points) A nautical mile is 6076 feet. A speed of one nautical mile per hour is a knot. In the next two questions, you will convert a speed in feet per minute to knots.

Answers

Using the information given in the table, and the speed - time relationship, the solutions to the exercises goes thus :

Using the information given in the table :

1.) The winning time for last year's race will be the lowest time on the table. Using the winning time column, the winning time for each city is :

Sydney = 14.75 minutes

San Francisco = 16.25 minutes

Mykonos = 25.5 minutes

2.)

The winning time of past winners cannot be determined as the exact distances of each city isn't given.

3.)

The information required to calculate speed is distance and time ;

Speed = (distance / time)

4.)

Distance = 1000 feets

Time = 5 minutes

Distance = 1000/5 = 200 ft/min

5.)

Speed in Knots ;

Speed in feets per hour

60 minutes = 1 hour

200 ft/ min × 60/1 hour = 12000 feets per hour

Speed in nautical mile per hour

1 nautical mile = 6076 feets

(12000 ft/hr) × (1/6076)feets = 1.975 nautical miles per hour

Therefore, speed in knots is 1.975 knots.
