She needs 23 boxes because 22.25 boxes doesn’t make sense.
The answer is 23 boxes not 22
Answer:
the graph of the parabola opens upwards.
Step-by-step explanation:
For any quadratic equation of the form
is true that:
if the main coefficient "a" is negative then the graph of the parabola opens downwards.
If the main coefficient "a" is positive, the parabola opens upwards
In this case the parabola is 
Note that 
and 
therefore the graph of the parabola opens upwards.
option : c. 2x + 15 = 145
cuz, the angles are vertical opposite angles
Answer:
-1, 0, 1, 2, 3
Step-by-step explanation:
Solve two equations:
-5 < 2n-1 => -4 < 2n => n > -2
and
2n-1 ≤ 5 => 2n ≤ 6 => n ≤ 3
so
-2 < n ≤ 3
then enumerate the possible values for n
-1, 0, 1, 2, 3
The order of length measurement starting with the smallest is 4.3 m, 433 cm, 4340 mm, and 0.043 km.
To compare the given measurements of length, they should have similar units. In this case, we can convert each length measurement to meter. The following conversion of different units to meter is listed below:
- 1 km = 1000 m
- 1 cm = 0.01 m or 100 cm = 1 m
- 1 mm = 0.001 m or 1000 mm = 1 m
Conversion of units to m:
- 0.043 km * (1000 m/km)= 43 m
- 433 cm * (0.01 m/cm) = 4.33 m
- 4340 mm * (0.001 m/mm)= 4.34 m
- 4.3 m
Lengths in order of size starting with the smallest:
- 4..3 m
- 433 cm or 4.33 m
- 4340 mm or 4.34 m
- 0.043 km or 43 m
