We are simply going to use direct proportion.

The smaller cake is 2/3 the larger cake:  let it be = (2/3)S. Let S be size of large cake

I would assume that the bottom tier refers to the larger cake.

Therefore, the bottom tier requires 3/5 cup of water.

Therefore, large cake size  S requires  (3/5) cup of water,

That means, small cake size,  (2/3)S  would require....
                                                                    = 2/3  * 3/5
                                                                     =  2/5  cup of water.
Therefore, Marcus is correct.

Round each number to the nearest ten. 283
arsen [322]
283 rounded to the nearest ten is 280
When rounding to the nearest ten look at the number to the right of the place you are rounding. In this case it is the 3. If the number is 5 or higher you go up to the nearest ten. If the number is lower than 5 like it is in this number you round down to the nearest ten.

A school district transported a total of 409 students and teachers to a zoo in buses and vans.
valina [46]

Answer: There are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.

Step-by-step explanation:

Since we have given that

Total number of students and teachers = 409

Let the number of vans be x

Let the number of buses be x+5

Number of students and teachers each bus transported = 55

Number of students and teachers each van transported = 12

According to question,

55(x+5)+12x=409\\\\55x+275+12x=409\\\\67x=409-275\\\\67x=134\\\\x=\frac{134}{67}\\\\x=2

Total number of students and teachers who rode to the zoo in buses will be

55(x+5)\\\\=55(2+5)\\\\=55\times 7\\\\=385

Total number of students and teachers who rode to the zoo in vans will be

12x\\\\=12\times 2=24

Hence, there are 385 students and teachers who rode to the zoo in buses and 24 students and teachers who rode to the zoo in trains.
