Answer:
504 millimeters (or 50.4 cm)
Step-by-step explanation:
Width of key in student calculator = 14 millimeter (1.4 cm)
Width of key in demonstration calculator = 2.8 cm
Thus, the demonstration calculator's dimensions are twice that of students' (in cm)
Also given, student calculator height as 252 millimeters (25.2 cm)
Thus demonstration calculator height will be twice of that = 50.4 cm (or 504 millimeters)
<h3>Answer:</h3>
D. If x2 = 9, then x = 3.
<h3>Explanation:</h3>
The converse reverses the order of phrases in "if p then q" so it becomes "if q then p". Here, that makes the converse ...
... If x^2 = 9, then x = 3.
The converse is not true (x may be -3), so we're finished with the problem. The appropriate choice is the one indicated above.
Answer:
P=20
Step-by-step explanation:
first find the distance between the points:
AB, BC,CD and DA
A(2,-3) , B(4,-3) , C(4,5) , D (2,5)
distance d= √(x2-x1)^2+(y2-y1)^2
for AB= d= √(4-2)^2+(-3-(-3))^2
AB=2
same thing for the rest of the lines
BC=√(4-4)^2+(5-(-3))^2
BC=8
CD=2
DA=8
perimeter=8+8+2+2=20
The % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.
<h3><u>Percentages</u></h3>
Given that last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639, to determine the % decrease in the number of scheduled passenger flights from February of 1999 to last February, the following calculation must be made:
- 709639 = 100
- 617624 = X
- 617624 x 100 / 709639 = X
- 61762400 / 709639 = X
- 87.03 = X
- 100 - 87.03 = X
- 12.97 = X
Therefore, the % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.
