The number of chaperones needed for a school field trip was s directly proportional to the number of students going on a field t
Korvikt [17]

Answer:

The correct answer is 16.

Step-by-step explanation:

Number of chaperones required for 96 students is 12.

Thus under each chaperone there are \frac{96}{12} = 8 students.

Now a total of 125 students are supposed to be sent on a trip.

Therefore the total number of chaperones required for these 125 students are \frac{125}{8}  = 15.625 ≈ 16. (converted to the highest integer because the leftover 5 students would need one more chaperones)

Therefore a total for 16 chaperones are required by the Wachusett Perineal School to take 125 students for a field trip.

If 1m = 3.3 ft, how many cubic feet is the Kuroshio Sea tank? Volume is 9,450. Show your calculations!
Naddika [18.5K]

Answer:

339604.65 cubic feet

Step-by-step explanation:

We are given that 1 m is equal to 3.3 ft.

1 m = 3.3 ft

This means that if we find the volume of a cube of 1 m, we have its volume as:

1^3 = 1 m^3

In the same way, the volume of a cube of 3.3 ft (1 m) is:

3.3^3 = 35.937 ft^3

This means that:

1m^3 = 35.937 ft^3

The Kuroshio sea tank has volume of 9450 m^3. Its volume in cubic feet is therefore:

1m^3 = 35.937 ft^3\\\\9450 m^3 = 9450 * 35.937 = 339604.65 ft^3

The volume of the tank is 339604.65 cubic feet.

kia thinks she can make her new product for $5.80. She plans to sell for $12. what is her percent mark up?
gavmur [86]
First, count the difference of the cost production and the selling cost
difference = 12 - 5.8
difference = 6.2

Second, transform the difference to percentage
percentage = difference/product cost × 100%
percentage = 6.2/5.8 × 100%
percentage = (620/5.8) %
percentage = 106.9%

The mark up cost is 106.9%

Can somebody explain to me how they got 3^4(x) = 3^3(x+2)? Then explain what happened to the 3 in 3^4 and the 3 in 3^3? Please a
musickatia [10]

Answer:

x=6

Step-by-step explanation:

81^x = 27 ^(x+2)

81 = 3^4    and 27 =3^3  so replace 81 and 27 in the equation

3^4^x = 3^3^(x+2)

When we have a power to a power we can multiply the exponents

a ^b^c = a^(b*c)

3^(4x) = 3^(3*(x+2))

Since the bases are the same, the exponents  have to be the same

a^b = a^c   means b=c

4x = 3(x+2)

Now we can solve for x

Distribute

4x = 3x+6

Subtract 3x from each side

4x-3x = 3x-3x+6

x = 6
