It forms a right triangle.

To find X you can use the Pythagorean theorem which would be written as x^2 = a^2 + b^2

This can be rewritten as x = sqrt(a^2 + b^2)

Using the dimensions of the tree the answer would be :

B. x = sqrt(8^2 + 13^2)

A figure is translated horizontally 4 units. Which drawling shows a correct translation?

mash [69]

Answer: A

Step-by-step explanation: It is the only one being mirrored horizontally as, if the question said to find the one translated vertically, D would be the answer. C is incorrect because it just repeats the first figure and B is incorrect because it is translated vertically in an incorrect manner.

So in the end, The answer would be A.

Jasmine tossed a coin 20 times. It lands on heads 14 times and tails 6 times. What is the relative frequency of landing on tails

Snowcat [4.5K]

Answer:

The relative frequency of landing on tails is 0.3.

Step-by-step explanation:

The relative frequency of an outcome A is:

The number of trials in which the outcome A happened divided by the total number of trials.

In this problem, we have that:

20 coin tosses, so 20 trials. On 6, it landed on tails.

6/20 = 0.3

This means that the relative frequency of landing on tails is 0.3.

Answer:

C. 176.6 Square feet (I think)

Step-by-step explanation:

I tried many different ways and got three of the answers above but I think this is the right one.

The equation to find area of a circular cone base: $A= \pi r^2$

We are given the diameter (15 Feet) but we need to find the radius. So we use the diameter to radius formula: $r = \frac{d}{2}$
Plug in numbers: $r=\frac{15}{2}$ ≈ $7.5$
Use the Area formula now that you have radius: $A=\pi 7.5^2$
Solve and get = $a = 176.71458676$
Looking at the options the closest one to our answer (off by one-tenth) is C.
