157.44
Step-by-step explanation:
To find area of triangle you have to multiply base times height then divided by 1/2. 19.2 cm being your height x 16.4 cm being your base, then divide by 2.
Answer:
area of the triangle = ½×base×height
½×19.2×16.4 = 157.44
so, the area of the triangle is 157.44cm³

Part IV: Last year's winner (9 points) Your sponsor will need to know how your average speeds compare to the speeds of past winners. In Part IV, you'll find out how to calculate boat speeds in knots (nautical miles per hour).
1. What was the winning time of last year's race for your city and boat? (2 points, one for each leg)
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.
4. If you travel 1000 feet in 5 minutes, what is your speed in feet per minute? (1 point)
5. What is your speed in knots? Hint: Use the number of minutes in an hour to convert the speed to feet per hour. Then use the number of feet in a nautical mile to convert feet per hour to knots. (2 points: 1 point for finding the speed in feet/hr. 1 point for converting to knots)

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 minutes2.)
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 minutesDistance = 1000/5 = 200 ft/min
5.)
Speed in Knots ;
Speed in feets per hour
60 minutes = 1 hour200 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.

A

Answers
Answer:
[tex]59.6[/tex] mm
Step-by-step explanation:
We know that the base times the height divided by two is the area, so we have that [tex](8.6*h)/2=256.28[/tex].
We can multiply both sides by [tex]2[/tex] to get [tex]8.6*h=512.56[/tex].
Lastly, we divide by [tex]8.6[/tex] on both sides to get [tex]h=512.56/8.6[/tex].

Answer:

Step-by-step explanation:
4x+3−x=12x−15
Combine 4x and −x to get 3x.
3x+3=12x−15
Subtract 12x from both sides.
3x+3−12x=−15
Combine 3x and −12x to get −9x.
−9x+3=−15
Subtract 3 from both sides.
−9x=−15−3
Subtract 3 from −15 to get −18.
−9x=−18
Divide both sides by −9.
x= –18÷–9
Divide −18 by −9 to get 2.

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

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 value of x and y.
Answers
Answer:
[tex]x=13[/tex]
[tex]y=23[/tex]
Step-by-step explanation:
[tex](12x - 41) + 5x = 180[/tex]
[tex]12x + 5x = 180 + 41[/tex]
[tex]17x = 221[/tex]
[tex] \frac{17x}{17} = \frac{221}{17} [/tex]
[tex]x = \frac{221}{17} [/tex]
[tex]x = 13[/tex]
[tex](12 \times 13 - 41) + 5(13) = 180[/tex]
[tex]115 + 65 = 180[/tex]
[tex]180 = 180[/tex]
[tex]vertical \: angles[/tex]
[tex](12x - 41) = 5y[/tex]
[tex]12 \times 13 - 41 = 5y[/tex]
[tex]115 = 5y[/tex]
[tex] \frac{115}{5} = \frac{5y}{5} [/tex]
[tex]y = \frac{115}{5} [/tex]
[tex]y = 23[/tex]
[tex]5y=12x-41[/tex]
[tex]5×23=12×13-41[/tex]
[tex]115=115[/tex]
We can use the two terms in x to find the value of x.
Angles on a line have a sum of 180°
⇒ (12x -41)° + 5x° = 180°
⇒ (12x + 5x -41)° = 180°
⇒ 17x° = 180 + 41°
⇒ x = 13
We can use the same principle of angles to find y
5x° + 5y° = 180°
since x = 13; 5(13) + 5y = 180
5y = 115
y = 23
∴ x = 13 & y = 23Find the measure of XYZ

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.
