Answer:
240 people
Step-by-step explanation:
According to the given data,
In each bus,there are total number of 36 students and 4 adults
So, total 40 people are in one bus so...
As, there are six Fields buses
=>40 x 6
=240
Answer: Total 240 people are going on the field trip.
1+2=3. 4/10+2/10=6/10. 3+ 6/10=3 6/10
9514 1404 393
Answer:
20
Step-by-step explanation:
As with any evaluation problem, take it step by step according to the order of operations.
The first thing you need to do here is compute a#b.
The given definition can be simplified a bit for evaluation purposes:
a#b = a²b -ab² = ab(a -b)
Then for a=3 and b=-2, you have ...
(3)#(-2) = (3)(-2)(3 -(-2)) = -6(5) = -30
Now, you are in a position to evaluate the expression you're asked for.

Answer:
C
Step-by-step explanation:
To determine how much she should use for every type of soil, we need to set up equations. We do as follows:
Let x = amount of the soil with 27% clay
y = amount of the soil with 15% clay
We have two unknowns so we need two equations.
First equation,
x + y = 27
Second equation,
.27x + .15y = (27)(.12)
.27 + .15y = 3.24
Solving x and y,
x = -6.75
y =33.75
Since we have a value that is negative, it would be impossible to make a 12% clay soil with the given soils.
