Answer:

10 pairs of socks for $11.99

Step-by-step explanation:

6.99/6 = 1.165

1.99/10 = 0.199

0.199 < 1.165

Answer:

6 pairs of socks for 6.99.

Step-by-step explanation:

Because 11.99 is almost $12 and 6.99 is almost $7, so 6 for 7 is better than 10 for 12. Also if you divide 11.99 by 10 you get 1.199 and if you divide 6.99 by 6 you get 1.165.

Find the value of x in the given right triangle. 10 х

ki77a [65]

Answer:

44.4

Step-by-step explanation:

Since we have a right triangle, we can use trig functions

sin theta = opp / hyp

sin x = 7/10

Taking the inverse sin of each side

sin^-1 (sin x) = sin^-1(7/10)

x = 44.427

Rounding to the nearest tenth

x = 44.4

Help! This is due today and I'm stuck on this problem.

Varvara68 [4.7K]

Answer:

280.6 $m^2$

Step-by-step explanation:

find the length of each side:

you're only given h = 9 m

the formula for h is $h=\frac{\sqrt{3} }{2} *a$ , where a is a side length of the hexagon

plug h in:

$9=\frac{\sqrt{3}}{2}*a\\\\a=9*\frac{2}{\sqrt{3}}\\\\$

a ≈ 10.392 m

now find the area of a triangle:

1/2 (10.392)(9) = 46.764 $m^2$

multiply that by 6 and you get 280.584 ≈ 280.6 $m^2$

you can also use the regular hexagon area formula instead of finding the individual area and multiplying by 6: $\frac{3\sqrt{3} }{2} *a^2$
