Step-by-step explanation:

The total surface area of the given pyramid is 304 sq units.

A pyramid is three dimensional shape. A pyramid has a polygonal base and flat triangular faces, which join at a common point called the apex.

Every face of the pyramid is triangular  except the base. The base is square shaped. So we will use the formula of area of triangle to find the area of each face of the pyramid. And we will use the formula of area of square to find the base area of the pyramid.

The area of triangle is = (1/2)×base×height

The are of square = (side)²

Given that the length and breadth of base is = 8 units

So, the area of base is = 8²=64 sq units.

Also the height of the each triangular face is 15 units.

So, the area of each face is = (1/2)×8×15

=4×15

=60 sq units.

So, the total area of four triangular faces of the pyramid = 4×60

=240 sq units.

Hence, the surface area of the pyramid = Area of four traingular faces + Area of square base

=240+64

=304sq units

Thus , The required surface area of the pyramid is = 304 sq units

The weights of the first and second packages are :

First package = 2.48 pounds

Second package = 2.6 pounds

Answer:

3rd is greater Than first.

Step-by-step explanation:

Weight of third package = 2.5 pounds

Comparing the weight of first and 3 rd package :

2.5 > 2.48

Weight of 3rd package > Weight of first package

First package :

2.48 pounds

Third package :

2.50 pounds

Greatest place value of the package weight is the unit value, 2 ; since the unit value is the same, we take the 2nd highest place value of the weight ;the tenth

Value of the tenth digit = 4

Value of the tenth digit in third package = 5

Since, 5 > 4 ; then 3rd weight package is greater than first weight package

Answer:

the longest side is AC

Step-by-step explanation:

The longest side will be opposite the largest angle.

4x+(2x-6) + (4x-4) = 180 (all triangle interior angles add up to 180 degrees)

simplify:

10x - 10 = 180

10x = 190

c= 19

angle B = 4(19) = 76 degrees

angle A = 2(19) - 6 = 32 degrees

angle C = 4(19) - 4 = 72 degrees

so the longest side is AC

Answer:

[tex]\frac{6}{25}[/tex] - [tex]\frac{8}{25}[/tex] i

Step-by-step explanation:

Assuming you mean

[tex]\frac{2i}{-4+3i}[/tex]

To simplify, rationalise the denominator

Multiply the numerator/ denominator by the conjugate of the denominator

The conjugate of - 4 + 3i is - 4 - 3i , then

= [tex]\frac{2i(-4-3i)}{(-4+3i)(-4-3i)}[/tex] ← expand numerator and denominator

= [tex]\frac{-8i-6i^2}{16-9i^2}[/tex] [ note that i² = - 1 ]

= [tex]\frac{-8i+6}{16+9}[/tex]

= [tex]\frac{6-8i}{25}[/tex]

= [tex]\frac{6}{25}[/tex] - [tex]\frac{8}{25}[/tex] i ← in standard form

Answer:

2x + 18 ≥ 21

x ≥ 2/3

Step-by-step explanation:

Let sum be X

2 times the sum means 2x

the sum of a number and 18 means x + 18

at least -21 means ≥ 21

put them together, and you get, 2x + 18 ≥ 21

If solving for x,

2x + 18 ≥ 21

2x ≥ 3

x ≥ 2/3

Answer:

168 seconds

I edited the answer.

Step-by-step explanation:

To find the the time taken for both lights to flash at the same time, we need to find the lowest common multiple of 28 and 24.

28 x 6 = 168, 24 x 7 = 168

The LCM of 28 and 24 is 168.

So it takes 168 seconds for both lights to flash at the same time.

Both lights will flash together again at 2 minutes and 8 seconds.

To find When will they flash together again if they flash together.

LCM is the method to find the smallest possible multiple of two or more numbers.

Given that,

A red light flashes once every 28 seconds

A green light flashes once every 24 seconds

A red light flashes every 28 seconds and green light flashes once every 32 seconds. Therefore,  we have to find their least common factor.

LCM(28 , 24) = 168

The red and green light will flash together after every 168 seconds.

Time  =168 seconds

Time =168 / 60 minutes

Time = 2 minutes and 8 seconds

The red and green light will flash together after every 2 minutes and 8 seconds.

Hence, both lights will flash together again at 2 minutes and 8 seconds.

Step-by-step explanation:

The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.

The given expressions are 2x³-3x²-3x+2 and x-2.

The factors are the polynomials which are multiplied to produce the original polynomial.

Here, the given polynomial can be factored as follows:

x-2 |2x³-3x²-3x+2| 2x²+x-1

      2x³-4x²

     (-)   (+)

___________

             x²-3x+2

             x²-2x

            (-)  (+)

___________

                 -x+2

                 -x+2

                (-)  (+)

____________

                   0

2x²+x-1 can be rewritten as 2x²+2x-x-1

= 2x(x+1)-(x+1)

= (x+1)(2x-1)

The factorisation of polynomial is (2x-1)(x+1). Therefore, option C is the correct answer.
