1 hr = 60 mins
10 hr = ... mins
600 mins + 39 mins = ... mins
639 mins + 24 sec=......mins
91 cm × 24 = ...
IDK what convention factors are tho...
Answer:
B) Only (-3, 5)
Step-by-step explanation:
Slot in the options into the equation
(-2, 4),
Compare with (x, y)
x = -2, y =4
y =-3x - 4
4 =( -3 * -2 ) - 4
4 = 6 - 4
This is not true hence, option A is wrong
Using (-3, 5)
x = -3, y= 5
5 = (-3*-3) - 4
5 = 9 - 4
This is correct hence, option B is correct
Option c is wrong because (-2,4) is not a solution to the equation
Option D is wrong because option B is correct
L = liz's age now
J = Jack's age now
L-1 and J-1 are their ages one year ago
L-1=3(J-1)
L-1=3J-3
L=3J-3+1
L=3J-2 (to be used later)
L+2 and J+2 are their ages in two years
L+2=2(J+2)
replace L by 3J-2
3J-2+2=2(J+2)
3J=2J+4
3J-2J=4
J=4 is Jack's age now
L-1=3(J-1)
L-1=3(4-1)
L-1=3*3
L-1=9
L=9+1
L=10 is Liz's age now
Answer:
Step-by-step explanation:
Given two non zero vectors, 
.
Let the angle between the two vectors = 
Given that:
Let us have a look at the formula for magnitude of addition of two vectors:
Where is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:
As per the given condition:
Squaring both sides:
So, the angle between the two vectors is:
Percent formula : is / of = % / 100
16 is what percent of 72...
is = 16
of = 72
% = x
sub into the formula
16/72 = x / 100
cross multiply because this is a proportion
(72)(x) = (100)(16)
72x = 1600
x = 1600/72
x = 22.2 % <===
