Answer:

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana

Step-by-step explanation:

We have these following probabilities:

1/4 probability that a lunch bag contains an apple.

1/3 probability that a lunch bag contains a banana.

What is the probability of randomly choosing a lunch bag that contains either an apple or banana?

P = \frac{1}{4} + \frac{1}{3} = \frac{3 + 4}{12} = \frac{7}{12}

7/12 probability of randomly choosing a lunch bag that contains either an apple or banana

The length of a rectangle is 2 cm less than it’s width.If the area of the rectangle is 35 cm^2,find the width
Elan Coil [88]

Answer:

7cm

Step-by-step explanation:

Area = Length x width

A = 35

w= L - 2

L = w+ 2

Now it becomes

35 = ( w+2) x w

35 = w^2 + 2w

W^2 + 2w - 35 = 0

By Factorization we have

( w + 7)( w-5)

w = 5cm

Since L = w + 2, we have

L = 5 + 2

= 7cm

A square and an equilateral triangle have equal perimeters. the area of the triangle is 
Ivenika [448]

a - length of side of a square

t - length of side of a triangle

The perimeter of a square: P_S=4a

The perimeter of a triangle: P_T=3t

We have the area of a triangle: A_T=16\sqrt3\ cm^2

The formula of an area of an equilateral trinagle: A_T=\dfrac{t^2\sqrt3}{4}

Substitute:

\dfrac{t^2\sqrt3}{4}=16\sqrt3    <em>multiply both sides by 4</em>

t^2\sqrt3=64\sqrt3     <em>divide both sides by \sqrt3</em>

t^2=64\to t=\sqrt{64}\to t=8\ cm

The perimeter of a triangle: P_T=3(8)=24\ cm

Substitute to the formula of a perimeter of a square:

4a=24       <em>divide both sides by 4</em>

a=6\ cm

The formula of a diagonal of a square: d=a\sqrt2

Substitute:

d=6\sqrt2\ cm
