A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules
A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?
Answer:
8 38/45 inches
Step-by-step explanation:
A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?
Let us represent:
Length of regular size chocolate bar = x
Length of king size chocolate bar = y
A regular size chocolate bar is 5 and 4/9 inches long.
x = 5 4/9 inches
If the king size bar is 3 and 2/5 inches longer,
Hence:
y = x + 3 2/5 inches
The length of the king size bar is calculated as:
5 4/9 inches + 3 2/5 inches
(5 + 3) + ( 4/9 + 2/5)
Lowest common denominator = 45
8 + (20 + 18/45)
8 38/45 inches
Mr. Kramer's patio is in the shape of a trapezoid. The trapezoid and its dimensions are shown below. What is the area of the patio? A 144 square feet B 360 square feet C 315 square feet D 252 square feet
Answer:
C 315
Step-by-step explanation:
(12 + 30) * 15/2 = 315
The area of the trapezoidal patio is 252 ft².
What is a trapezoid?A trapezoid is a polygon that has only one pair of parallel sides. These parallel sides are also called parallel bases of trapezoid. The other two sides of trapezoids are non-parallel and called legs of trapezoids.
Given that, Mr. Kramer's patio is in the shape of a trapezoid, we need to find its area,
So, the area of the trapezoid is = sum of the parallel sides × height/2
= 12 + 30 × 12/2
= 42 × 6
= 252
Hence the area of the trapezoidal patio is 252 ft².

The foot of a ladder is placed 18 feet from a wall. If the top of the ladder
rests 24 feet up on the wall, find the length of the ladder.
26 feet
27 feet
29 feet
O 30 feet
Answer:
I'm not sure
I think its 30 or 26
Step-by-step explanation:
Answer:
30 feet
Step-by-step explanation:
The ladder laying against the wall will create a right triangle.
The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.
You can use the pythagorean theorm so
[tex]a^{2} +b^{2} =c^{2}[/tex] so you plug in the values
[tex]18^{2}+24^{2} =c^{2} \\324+576=c^{2} \\900=c^{2} \\\sqrt{900} =\sqrt{c^{2} } \\30=c[/tex]

4. On a 3-hour trip, a car travels 156 miles.
What is the average speed of the car on this
trip?
Answer:
v = 52 mph
Step-by-step explanation:
Given that,
The distance travelled by the car, d = 156 miles
Time, t = 3 hour
We need to find the average speed of the car. The formula for the average speed is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{156}{3}\\\\v=52\ mph[/tex]
So, the average speed of the car is equal to 52 mph.
