Vinvika [58]
If we multiply 14,560 with 10 we will get <em>145,600</em>.
We have 10 in question we will add 1 zero in the product. the number of zeros we have on multiplicating side the number of zeros we will add in the product.
Example- 14,560 * 1000 = 14,560,000.

Maksim231197 [3]

Step-by-step explanation:

The angle between vectors is given by

\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|}

The magnitudes for the vectors are as follows:

|\vec{\textbf{a}}| = \sqrt{a_x^2 + a_y^2 + a_z^2}

\:\:\:\:\:\:\:=\sqrt{(2)^2 +(-5)^2 + (3)^2} = 6.16

|\vec{\textbf{b}}| = \sqrt{b_x^2 + b_y^2 + b_z^2}

\:\:\:\:\:\:\:= \sqrt{(3)^2 + (1)^2 + (4)^2} = 5.10

The dot product between the vectors is

\vec{\textbf{a}}\cdot \vec{\textbf{b}} = (2)(3) + (-5)(1) + (3)(4) = 13

Therefore, the angle between the two vectors is

\cos{\theta} = \dfrac{\vec{\textbf{a}}\cdot \vec{\textbf{b}}}{|\vec{\textbf{a}}||\vec{\textbf{b}}|} = \dfrac{13}{(6.16)(5.10)}

or

\theta = 65.56°

Andy got a 32% discount on all his purchases at his favorite shop. if he saved $64 on the total bill, the bill amount without th
rosijanka [135]
Let x be the value of the his purchases without the discount. The $64 is the value of the 32% discount. 
                                   64 = 0.32x      ; x = 200
Thus, he should have paid $200 if there was no discount. The amount he paid (p) is only 68% of this value. p = (0.68)(200) = 136. Hence, he paid only $136.
