suface area of cuboid 9 5 4
Answers
The cuboid in question has a surface area of 202 square units.
We must sum together the areas of all six faces to determine a cuboid's surface area.
The dimensions of the given cuboid are:
length (l) = 9 units
width (w) = 5 units
height (h) = 4 units
The area of each face is given by:
Top and bottom faces:\(lw = 9 * 5 = 45\) square units each
Front and back faces: \(lh = 9 *4 = 36\) square units each
Left and right faces: \(wh = 5 * 4 = 20\) square units each
Therefore, the total surface area of the cuboid is:
\(2(lw + lh + wh) = 2(45 + 36 + 20)\\ = 2(101) \\= 202 \ square \ units\)
Hence, the surface area of the given cuboid is 202 square units.

There are six pizzas there are 36 players on the team. If each member has one slice and each pizza has eight slices how much pizza in fraction form will be left over.
Answers
There will be 12 slices of pizza left over, which can be expressed as 3/2 or 1 1/2 slices in fraction form.
To find out how much pizza will be left over, we need to calculate the total number of slices available and subtract the number of slices consumed by the players.
Given that there are six pizzas and each pizza has eight slices, the total number of slices available is 6 pizzas * 8 slices/pizza = 48 slices.
Since there are 36 players on the team, and each player has one slice, the total number of slices consumed is 36 slices.
To determine the remaining slices, we subtract the consumed slices from the total available slices: 48 slices - 36 slices = 12 slices.
Therefore, there will be 12 slices of pizza left over.
To express this as a fraction, we can write it as 12/1, which simplifies to 12. This means there will be 12 whole slices of pizza left over.
If you would like to express it as a fraction in its simplest form, you can write it as 12/8. By dividing both the numerator and denominator by their greatest common divisor, which is 4, we get 3/2. So, in fraction form, there will be 3/2 or 1 1/2 slices of pizza left over.

3. divide 50 by 50 to isolate the t. now t is by itself since 50 divided by 50 is 1.

Assume that when t = 0 the radius is 20 million miles and increasing.) R(t) =
Answers
Let R be the radius in millions of miles and let t be the time in days. Assume that when t = 0 the radius is 20 million miles and increasing then R(t) = 20 + 1.6sin(2πt/5.2).
The equation for a sine wave is y = A sin (Bx + C) where A is the amplitude, B is the frequency and C is the phase shift.
In this case, the amplitude is 1.6.
Since the radius changes by a maximum of 1.6 million miles.
The frequency is 2π/5.2 (one full cycle of the sine wave in 5.2 days)
The phase shift is 0, since when t = 0 the radius is increasing.
The equation then becomes R(t) = 20 + 1.6sin(2πt/5.2)

Let x and y be the number of months and the total balance of the account, respectively. Therefore, when x=0, y=$500 (starting amount) and, after 1 month, $75 are added to that amount, after 2 months, 2*$75, and so on.
Thus, the equation is
\(y=500+75x\)Where 75 is the slope of the line (m=75), and the y-intercept is equal to 500 (b=500).
2 years is equal to 2*12=24 months; therefore,
\(\Rightarrow y=500+75(24)=500+1800=2300\)After two years, the total balance is $2300.
the difference in elevation of a helicopter and a submarine is 18 1/2 meters elevation of a submarine is -7 3/4 meters what is the elevation of the helicopter
Answers
Answer
The elevation of the helicopter = +10.75 meters
Explanation
Before starting, note that
18 1/2 = 18.50
-7 3/4 = -7.75
And the ground has an elevation of 0, spots above the ground have positive elevations and spots below the ground have negative elevation.
Let the elevation of the helicopter be x.
And the elevation of the submarine be y.
The difference in elevation of a helicopter and a submarine is 18.50 meter
x - y = 18.50
Elevation of a submarine is -7.75 meters (there's negative sign in front because a submarine is under the sea level)
So, y = -7.75
Recall that
x - y = 18.50
x - (-7.75) = 18.50
x + 7.75 = 18.50
x = 18.50 - 7.75
x = +10.75 m
The elevation of the helicopter = +10.75 meters

What is the area of the square that measures 3.1 m on each side
Answers
The area of the square with a side length of 3.1 meters is 9.61 square meters.
To find the area of a square, we need to multiply the length of one side by itself. In this case, the square has a side length of 3.1 m.
Area of a square = side length × side length
Substituting the given side length into the formula:
Area = 3.1 m × 3.1 m
To perform the calculation:
Area = 9.61 m²
It's worth noting that when calculating the area, we are working with squared units. In this case, the side length is in meters, so the area is expressed in square meters (m²). The area represents the amount of space enclosed within the square.
Remember, to find the area of any square, you simply need to multiply the length of one side by itself.
The area of the square with a side length of 3.1 meters is 9.61 square meters.

A person makes an overseas phone call. The telephone company charges 65 cents for the first minute and then 75 cents for each minute thereafter. Because it's an overseas phone call, there is also a 55 cent service charge. If the phone call cost $ 19.20 , how many minutes did this person talk?
Answers
Answer:
25 minutes.
Step-by-step explanation:
A person makes an overseas call.
The telephone company charges 65 cents for the first minute.
Then 75 cents for each minute thereafter.
There is a 55 cent service charge.
1 dollar = 100 cents
65 cents = $0.65
75 cents = $0.75
55 cents = $0.55
For a phone call that cost $19.20 ;
Subtracting the service charge and the first minute charge from overall cost we get;
$19.20 - $0.55 - $0.65 = $18
For every additional minute there is a charge of $0.75
How many minutes make $18 ;
Cross multiplying this gives;
\(\frac{18}{0.75} * 1\) = 24 minutes.
So the call lasted 24 minutes + 1 minute = 25 minutes.
