What is the value of x? If necessary leave your answer in the simplest radical form.
frutty [35]
<h3>Answer:  32</h3>

Explanation:

This is a 30-60-90 triangle as shown by the angles. These types of triangles have their shortest leg opposite the smallest angle, and the connection between the short and long legs is

long = short*sqrt(3)

We see that the long leg is 16*sqrt(3) units long, which must mean the short leg is 16 units. This doubles to 32 when we go from short leg to hypotenuse

hypotenuse = short*2

Lucy’s parents built a swimming pool in the backyard. Use 3.14 for π.
Neporo4naja [7]

Answer:

Distance around the pool = 162.8 feet

Area of the pool = 957 square feet

Step-by-step explanation:

Distance around the swimming pool = Perimeter of the pool

Perimeter of the pool which is a composite figure will be,

= Circumference of the semicircle + Sum of three sides of the pool

= πr + 2×(length of the pool) + width of the pool

= 3.14×(10) + 2×40 + 20

= 62.8 + 80 + 20

= 162.8 ft

Area of the pool = Area of the semicircle + Area of the rectangular pool

                           = \frac{1}{2}(\pi)(r)^{2}+(\text{length}\times \text{Width})

                           = \frac{1}{2}(3.14)(10)^2+(40\times 20)

                           = 157 + 800

                           = 957 square feet

A coin is tossed times and comes up heads times. Use the Empirical Method to approximate the probability that the coin comes up
Vedmedyk [2.9K]

Answer:

P(head) = 0.5600

Step-by-step explanation:

Given

n = 500 -- number of toss

head = 280 --- outcomes of head

<em>See comment</em>

Required

Empirical probability of head

This is calculated as:

P(head) = \frac{n(head)}{n}

P(head) = \frac{280}{500}

P(head) = 0.5600
