Answer:

$d=\sqrt{2,537}\ m$ or $d=50.37\ m$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points in three dimensions is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}+(z2-z1)^{2}}$

Let

$A(5,3,1)$ -----> coordinates of the barrel of her gun

$B(38,41,3)$ -----> coordinates of the target

substitute the values

$d=\sqrt{(41-3)^{2}+(38-5)^{2}+(3-1)^{2}}$

$d=\sqrt{(38)^{2}+(33)^{2}+(2)^{2}}$

$d=\sqrt{1,444+1,089+4}$

$d=\sqrt{2,537}\ m$

$d=50.37\ m$

chet counts balloons for a party counts 13 bunches of balloons each bunch has 5.how many balloons does chet count.

Hoochie [10]

65 balloons are counted by Chet

<u>Solution: </u>

Given that

Chet counts balloons for a party

Number of bunches of balloons counted by Chet = 13

Also each bunch has 5 balloons.

Need to calculated how much balloons is counted by Chet

Number of balloons in 1 bunch = 5

Number of balloons in 13 bunches = 13 x Number of balloons in 1 bunch = 13 x 5 = 65

As number of bunches of balloons counted by Chet = 13

So number of bunches of balloons counted by Chet = Number of balloons in 13 bunches = 65

Hence 65 balloons are counted by Chet.
