ANSWER:
Instead of greater than, the inequity symbol should be greater than or or equal to.

Step-by-step explanation:
We know the variable x represents the number of students. We also know there are 5 chaperones attending; this makes x+5 , by 2.50
It costs $2.50 per person; this means we multiply the number of people, x+5, by 2.50:

2.50(x+5)

The class has $90 to spend; this means they can spend up to and including $90. This gives us
90>2.50(x+5)

The accumulated (future) value is given by the formula
F=P(1+i)^n
where 
P=amount of deposit (made at the beginning of the first period)
i=monthly interest, APR/12 = 3%/12 =0.0025
n=number of periods (month)

For example, the future value for the 6th month is
F(6)=1000(1.0025^6)=1015.09  (to the nearest cent)

Here is a schedule of the values,
i=month
F(i) = value at the end of month i.

  i   F(i)
 0  1000.0 
 1  1002.5 
 2  1005.01
 3  1007.52
 4  1010.04
 5  1012.56
 6  1015.09

sveta [45]

Answer:

  No

Step-by-step explanation:

The volume of a cube is the cube of the edge length, so the edge length of the cube-shaped block is ...

  edge length = ∛(64 cm³) = 4 cm

Then the smallest cross-section will be a square of edge length 4 cm, so will have an area of (4 cm)² = 16 cm².

The 16 cm² shape will not fit through an 8 cm² hole.

What is 90 plus negative 35
Dima020 [189]
The addition of a negative is basically the same as subtraction.

Since your adding -35 to 90, your just taking away 35 from 90.

You would set up the problem like this:

90 + – 35

Or you could write it out like this:

90 – 35

Either way, 90 + – 35 = 55
