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)
Perimeter of a square=4 x side
Data:
Perimeter=240 in
Then:
240 in=4* side
side=240 in/4
side=60 in.
answer: The lenght of one side of Steve´s dog pen is 60 in.
Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A = 
and l = 
, thus
V = × ( cancel 21 and 3 by 3 and 2 and 8 by 2 )
= 
× 
= 7 × 4 = 28 units³
I believe you meant that the interest rate is 6%. Interest rates are given as percents.
To find the simple interest, we just multiply the principal amount by the rate and then by the number of years.
600 x 0.06 x 3 = 108
The total amount including interest will be 708.
1.20(35)
this would be the same as :
(1 + 0.2)* 35 <==
or it also could have been 35 + 0.20(35)
