Answer:
a=9.641, b=11.49
Vector will be 9.641 i + 11.49 j
Step-by-step explanation:
We have given that vector V has the magnitude of 15
And it makes an angle of 50
with positive x axis
Now let the x component of vector V is a and y component of vector V is b
So 

In vector form 9.641 i+11.49 j
A=4-3b
subtract 4 from both sides
a-4=-3b
divide by -3 for both sides
(a-4)/-3 = b
135 and 1/2 should be correct.
Answer:
No, he does not have enough
Step-by-step explanation:
To decorate each cupcake, Henry needs 3 walnuts. Each package has 27 walnuts. With each cupcake needing 3 walnuts, Henry can decorate 9 cupcakes in one package. He has 5 packages which means he can decorate 9*5=45 cupcakes. However, he is making 4 dozens which is 4*12=48. He will not have enough.
