Answer: The temperature dropped 8 degrees.

Step-by-step explanation:

The initial temperature was T0, and each hour the temperature dropped by 2°, for 4 hours.

So we can write the temperature as a function of time in the next way:

T(t) = T0 - (2°/h)*t

where t is the number of hours since the temperature started to drop.

The temperature drop for four hours, so we have that the final temperature is:

T(4h) = T0 - (2*4)°= T0 - 8°

then we can calculate the difference between the final and initial temperature as:

T(4h) - T(0h) = T0 - 8° - T0 = -8°

This means that in Friday morning the temperature dropped by 8 degrees.

sergejj [24]
740-707.60=32.40
707.60-675.20=32.40
675.20-642.80=32.40
so that means every month you are paying 32.40$ bill. to get how many months you can pay phonebills without depositing any more money devide the 740/32.40=22.83 but you can not pay bill for the 0.83 month so answer will be 22 months

  • area of triangles
  • area of rectangle
  • PEMDAS
<h3>tips and formulas:</h3>
  • rectangle opposite sides are equal
  • area of rectangle:l×w
  • area of triangle:½×h×b
<h3>let's solve:</h3>

the area of the rectangle is

4×7 in²

28 in²

the area of above triangle is

½×6×7 in²

3×7 in²

21 in²

the area of left side triangle is

½×5×4 in²

2×5 in²

10 in²

therefore,

the area of the polygon is

28+21+10 in²

<h3>59 in²</h3>

Alenkinab [10]
The inequality should be
12 \leqslant 12x  < 180
The sign on the right is only a 'smaller than' sign because he spent less than 180.
On the left, assuming that even if Calvin took nobody (poor Calvin), we should assume that he at least went himself, hence he spent a minimum of $12.
