A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
Angelica is 23
Steps
Use the equation x=2j-5
Plug in jahiems age (14) for j and solve for c
a repeating decimal is placed over 9's instead of 0's. for example: 0.23 = , but 0.232323... =
a) x = 0.121212
b) 100(x) = 100(0.121212)
100x = 12.1212
c) 100x = 12.1212
- <u> x = 0.1212</u>
99x = 12
x =
d) -2 <em>= -2 when simplified</em>
The number is rational becase it has a repeating decimal
Given that the die-cast has been represented by 3/16 in to 1 foot, We are are required to calculate for the actual measure of a toy measuring 6.5 inches wide and 8.5 inches long;
the actual width will be given by:
(6.5÷3/16)×1
=34.66666667
=35 feet
The actual length will be given by:
(8.5÷3/16)×1
=45.333
=45 feet
905 or 2045 because I think those are the right answer
