Answer:

(D)

Step-by-step explanation:

The given vector is  (6,-3), the magnitude of the given vector is gievn as:

m=\sqrt{(x)^2+(y)^2}

Putting x=6 and y=-3, we get

m=\sqrt{(6)^2+(-3)^2}

m=\sqrt{36+9}

m=\sqrt{45}

m=3\sqrt5

Thus, the length of the given vector is 3\sqrt5 units.

Therefore, option D is correct.

in year 4 the store sold 112% of the total number of scooters sold during the previous three years combined determine the number
Margarita [4]

Answer:

2, 240

Step-by-step explanation:

In the table, the values should be

Year 1   725  

Year 2   579

Year 3   696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

\frac{112}{100} =\frac{x}{2000}

We solve through cross multiplication of numerator and denominator of the opposite fraction.

112(2000)=100(x)\\224000=100x\\2,240=x

The percent discount is 30%.
If you multiply $32 by .30, you will get $9.60. That is the amount of the discount. If you subtract $9.60 from $32, you will get $22.40 which is what he paid before tax. Therefore the percent discount is 30%.

Annie has 3/2 pounds of cookie dough. If she needs 1/16 of a pound of cookie dough to make one cookie, how many cookies can she
Zanzabum

Answer:

\boxed{\sf 24\ cookies}

Step-by-step explanation:

1 cookie = 1/16 of a pound of cookie

If we want to find how many cookies can be made by 3/2 pounds ( 1.5 pounds) then we need to divide 3/2 pounds by 1/16

=> \frac{3}{2} / \frac{1}{16}

=> \frac{3}{2} * 16

=> 3*8

=> 24 cookies
