Yanka [14]

Answer:

P(either almond or cashew) = ⅔

Step-by-step explanation:

We are told that the bag contains a mixture of almonds walnuts and cashews of equal number.

Since the 3 nuts are equal in number, they will have a ratio of 1:1:1.

So, when a nut is chosen randomly,

Probability of choosing almond = 1/3

Probability of choosing cashew = 1/3

Thus,

Probability of choosing either almond or cashew in a random selection will be the sum of their individual probability.

So,

P(either almond or cashew) = ⅓ + ⅓ = ⅔

Rewrite f(x)=x2+8x-20 in the form that would most easily help you identfiy the zeros of the function

den301095 [7]

Answer:

$f(x) = (x+ 10)(x - 2)$

Step-by-step explanation:

We want to rewrite

$f(x) = {x}^{2} + 8x - 20$

in the form that would most easily help you identfiy the zeros of the function.

This the same as writing in factored form.

$f(x) = {x}^{2} + 10x - 2x - 20$

Factor by grouping:

$f(x) = {x}(x+ 10)- 2(x + 10)$

Factor further to get:

$f(x) = (x+ 10)(x - 2)$

A circle with radius 16 centimeters is inscribed in a square.Which is the area of the shaded region? A. 804.25 square feet B. 10

Dmitrij [34]

Answer:

Area of shaded region = 220.16 ft²

Explanation:

The diagram associated with this question is shown in the attached image

Unit in diagram is ft, so I'll use this unit in the answer

We are given that a circle with radius 16 ft is inscribed in a square

We know that the radius of an inscribed circle in a square is equivalent to half the length of the side of the square

This means that:

side length of the square = 2 × radius = 2 × 16 = 32 ft

From the diagram, we can note that:

area of shaded region = area of square - area of circle .............> equation I

1- getting area of square:

Area of a square is the square of its side length

This means that:

Area of square = (32)² = 1024 ft²

2- getting the area of the circle:

Area of circle = πr² = 3.14 × (16)² = 803.84 ft²

3- getting area of shaded region:

Use equation I

area of shaded region = area of square - area of circle

area of shaded region = 1024 - 803.84 = 220.16 ft²

Hope this helps :)
