When subtracting fractions, you need to make sure the denominators are the same. In 2/3 - 1/2, the denominators are different. To make them the same, find the least common denominator. In this case, the common denominator is 6

2/3 becomes 4/6

1/2 becomes 3/6

Now subtract the fractions with the common denominator

4/6 - 3/6 = 1/6

The answer is 1/6

Answer:

7/6 or 1 1/6

Step-by-step explanation:

First, multiply both denominators so that they are both the same and equal each other. In this case that number is 6. Once they are both have the same denominator, you can add the numerators and keep the same denominator since it's the same thing. So you would add 4 plus 3 and get 7 as your numerator and keep 6 as your denominator,

2/3 = 4/6

1/2= 3/6

4/6 + 3/6 = 7/6 or 1 1/6

Probability. A professor rides his bike to work some days and drives his car on the other days. On any day there is an 80% chanc
Artyom0805 [142]

Answer:

0.09

Step-by-step explanation:

Given :

P(bike) = 0.8

P(car) = 0.2

P(Late given car) = P(Late | car) = 0.05

P(Late given bike) = p(Late | bike) = 0.1

Probability that professor is late :

P(late) = [P(Late | car) * p(car)] + [p(Late | bike) * p(bike)]

P(late) = [0.05 * 0.2] + [0.1 * 0.8]

P(late) = 0.01 + 0.08

P(late) = 0.09

the length of one of the diagonals of a quadrilateral is 10 cm and the particular drawn from the opposite vertices to this diago
loris [4]

Answer:

Therefore the area of the quadrilateral =35 cm²

Step-by-step explanation:

Given, the length of one of diagonal of quadrilateral is 10 cm and perpendicular drawn from the opposite vertices to this diagonal are the length of 2.8 cm and 4.2 cm.

A diagonal divided a quadrilateral into two triangle.

Therefore the area of the quadrilateral

= sum of the area of the triangles

=(\frac{1}{2}\times 10\times 2.8+ \frac{1}{2}\times 10\times 4.2)cm²      [ area of a triangle= \frac{1}{2}\times base\times height]

=35 cm²

Can somebody help find the surface area if this
GrogVix [38]

The total surface area of the object shown in the diagram is 164 inches.

<h3>What is the total surface area?</h3>

The total surface area of a 3-dimensional object is the sum of the areas of the faces or surfaces of a 3-dimensional object. The object shown is the net of a cuboid.

Total surface area of a cuboid = 2 (lw + wh + lh)

where:

• l = length

• w = width

• h = height

2 { (10 x 3) + (10 x 4) + (4 x 3)}

2 (30 + 40 + 12)

2 x 82 = 164 inches
