Answer:

t = 2, t = 3, t = 4, and t = 6.

Step-by-step explanation:

So, we can plug in each t value into the equation to see if it is correct.

9(2) ≤ 107

18 ≤ 107

This is correct because the equation is looking for something that is less than or equal to 107.

9(3) ≤ 107

27 ≤ 107

Same reason as stated above.

9(4) ≤ 107

36 ≤ 107

Same reason as stated above.

9(6) ≤ 107

54 ≤ 107

Same reason as stated above.

Therefore, t = 2, t = 3, t = 4, and t = 6 are all solutions to the inequality.

Answer:

Step-by-step explanation:

5a. 7 < x

b. 2< 2x

c. 8 > x

d. 3 > x/29

joe = j

christina = c

Aaron = a

j = 3a , c = a-6 total ages is 149

149 = j + c+ a

149 = 3a + a-6 + a

149 = 5a-6

add 6 to both sides

149 + 6 = 5a-6+6

155 = 5a

a = 155/5

a = 31

c = a - 6

c = 31 - 6

c = 25

A hotel wants to put a fence around a circular spa. The radius of the spa is feet. If the fence is built along the immediate edg

MariettaO [177]

For this case we must find the perimeter of the fence, in a circular way, knowing that the perimeter of a circle is given by:

$P = 2 \pi*r$

Where "r" represents the radius of the circle, in this case $r = \frac {5} {\sqrt {2} -1}$

Substituting in the perimeter equation we have:

$P = 2 \pi * \frac {5} {\sqrt {2} -1}$

Rationalizing we have:

$P = \frac {2 \pi * 5 (\sqrt {2} +1)} {(\sqrt {2} -1) * (\sqrt {2} +1)}\\P = \frac {2 \pi*5 \sqrt {2} +2 \pi*5} {2-1}\\P = 10 \pi \sqrt {2} +10 \pi$

Taking out common factor $\pi$ :

$P = (10 \sqrt {2} +10) \pi$

Answer:

$P = (10 \sqrt {2} +10) \pi\ feet$
