Answer:

D 5

Step-by-step explanation:

3x+2 > 14 10 -x ≤7

Solve the first inequality

Subtract 2 from each side

3x+2-2 >14-2

3x>12

Divide each side by 3

3x/3 >12/3

x >4

Now solve the second inequality

10 -x ≤7

Subtract 10 from each side

10-x-10 ≤7-10

-x≤-3

Divide each side by -1, remembering to flip the inequality

x ≥3

Both of these must be true The only number from the choices that is true for both is 5

There is a balcony that forms part of a circle around a stage, and they need to put up a safety railing. How long of a railing d

alexandr1967 [171]

A sector is a part of a circle that is formed by two radii, and an arc. So that the length of the safety railing required is 31.4 feet.

A sector is a part of a circle that is formed by two radii, and an arc, thus forming a central angle.

Thus the required length of safety railing can be considered as the arc of the sector.

So that;

length of an arc = (θ / $360^{o}$ ) * 2 $\pi$ r

where θ is the measure of the central angle of the sector, and r is the radius of the sector.

From the given question, θ = 45°, and r = 40 feet.

So that,

length of the safety railing = (45° / $360^{o}$ ) * 2 * 3.14 * 40

= 0.125 * 2* 3.14* 40

length of safety railing = 31.4

Therefore, the length of the safety railing required is 31.4 feet.

Please help me fast and show all your work please thx

Okay so the first thing you for for is to see if you can reduce your numbers and you can in this problem. You can reduce the 8 and 12 by 4, meaning that you can divide them by 4. So your problem would now be 2x7/3. Now to calculate your product you just times 2x7 and you’re answer is 14/3 :)
