Answer: 8.3 meters per second.

Step-by-step explanation:

Given : A hot air balloon descended 99.6 meters in 12 seconds.

then, the average rate of descent is given by :-

\text{Average rate of descent}=\dfrac{\text{\text{Distance descended }}}{\text{Time}}\\\\\Rightarrow\ \text{Average rate of descent}=\dfrac{99.6}{12}\\\\\Rightarrow\ \text{Average rate of descent}=8.3

Therefore, the balloon's average rate of descent in meters per second = 8.3 meters per second.

The legs of an iscosceles triangle have lengths 3x-1 and -x +27. The base has length 5x+1. What is the length of the base
asambeis [7]

Answer: 36

Step-by-step explanation:

The legs are given to be :

3x - 1 and -x + 27

The base = 5x + 1

One of the properties of an isosceles triangle is that two sides are equal , that is the two legs are equal. This means that

3x - 1 = - x + 27

3x + x = 27 + 1

4x = 28

x = 7

To calculate the length of the base, substitute x = 7 into the length of the base given , that is

Length of the base = 5(7) + 1

L = 35 + 1

L = 36

Given this unit circle, what is the value of x? (x, -7/10)(1,0)​
Paraphin [41]

Answer:

x = - \frac{\sqrt{51} }{10}

Step-by-step explanation:

the equation of a circle centred at the origin is

x² + y² = r² ( r is the radius )

The radius of a unit circle is r = 1

substitute (x, - \frac{7}{10} ) into the equation and solve for x

x² + (- \frac{7}{10} )² = 1²

x² + \frac{49}{100} = 1 ( subtract \frac{49}{100} from both sides )

x² = 1 - \frac{49}{100} = \frac{51}{100} ( take square root of both sides )

x = ± \sqrt{\frac{51}{100} } = ± \frac{\sqrt{51} }{10}

since the point is in the 3rd quadrant then x < 0

x = - \frac{\sqrt{51} }{10}
