360 is divisible by which of the following numbers 2,3,4,5,6,9, or 10
alukav5142 [94]

Answer:

360 is divisible by all numbers 2,3,4,5,6,9 or 10 .

Step-by-step explanation:

Given : 360

To find : 360 is divisible by which of the following numbers 2,3,4,5,6,9, or 10

Solution : We have given

Numbers 2,3,4,5,6,9, or 10.

For number = 2

\frac{360}{2} = 180.

For number = 3

\frac{360}{3} = 120.

For number = 4

\frac{360}{4 } = 90.

For number = 5

\frac{360}{5 } = 72.

For number = 6

\frac{360}{6 } = 60.

For number = 9

\frac{360}{9 } = 40.

For number = 10

\frac{360}{10 } = 36

Therefore, 360 is divisible by all numbers 2,3,4,5,6,9 or 10 .

Find the projection of u onto v<br> URGENT HELP
padilas [110]

Given:

Two vectors are:

u=\left

v=\left

To find:

The projection of u onto v.

Solution:

Magnitude of a vector v=\left is:

|v|=\sqrt{a^2+b^2}

Dot product of two vector v_1=\left and v_2=\left is:

v_1\cdot v_2=a_1a_2+b_1b_2

Formula for projection of u onto v is:

Proj_vu=\dfrac{u\cdot v}{|v|^2}v

Proj_vu=\dfrac{\left \cdot \left }{(\sqrt{2^2+17^2)^2}}\left

Proj_vu=\dfrac{0\cdot 2+6\cdot 17}{4+289}\left

Proj_vu=\dfrac{0+102}{293}\left

On further simplification, we get

Proj_vu=\dfrac{102}{293}\left

Proj_vu=\left

Proj_vu=\left

Therefore, the projection of u onto v is Proj_vu=\left.

Stacey is making candles to sell at the craft fair. She has 5 pounds of wax to make the candles. She needs 18 pound of wax for 1
SIZIF [17.4K]

Answer:

Step-by-step explanation:

To determine how much wax you will need, you will first need to decide on ... (ounces needed) ÷ 16 (ounces in 1 pound) = (pounds of wax needed). For example, let's say you wanted to make 25 candles in our 8 oz Candle Tins ... 5 x 25 = 125 oz of wax ... It's always better to have a little wax left over than to not have enough!
