If you are asking for whose calculations are more accurate that would be Anja's because her's goes out to a further decimal value.

The distance between the coordinates in meters is 138.92m

Using the distance formula to calculate the distance between the coordinates as shown:

$D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} \\$

Given the coordinate points C(-5, 8) and V (7, 1)

Substitute the given coordinates into the formula

$D = \sqrt{(7+5)^2+(1-8)^2} \\D = \sqrt{(12)^2+(-7)^2} \\D = \sqrt{144+49} \\D = \sqrt{193} \\D=13.892 units$

Given that 1 unit = 10metres

D = 13.892 * 10

D = 138.92 meters

Hence the distance between the coordinates in meters is 138.92m

PLLZZZZZZZ HELP!!!!!

Gnoma [55]

The answer is 8 and heres why:

$64^{\frac{3}{6}} \\\frac{3}{6}=\frac{1}{2} \\ \\64^{\frac{1}{2}} \\ \\\mathrm{Factor\:the\:number:\:}\:64=8^2 \\\left(8^2\right)^{\frac{1}{2}} \\ \\\mathrm{Apply\:exponent\:rule}:\quad \left(a^b\right)^c=a^{bc} \\\left(8^2\right)^{\frac{1}{2}}=8^{2\cdot \frac{1}{2}}=8$

And that is how you solve this promblem :-)

PLEASE HURRY<br> How do i solve these problems

Tatiana [17]

Answer:

X = 13

X = 70

Step-by-step explanation:

1. Since it is a right angle set the equation up as X +2 + 75 = 90.

X =13

2. Set up x - 20 + 40 = 90 since right triangles are 90 degrees

x = 70
