Answers

3.032 > 3.023
3.032 is greater because instead of the 2 in 3.023, there is a greater value in the second number, 3.

Hope this helps :)
3.032 > 3.023 because 32 is bigger than 23.

Large chocolate bar has a base area of 48.96 square feet and its length is 0.6 foot shorter than twice its width. Find the length and width 

Answers

The length and the width of the bar are 6.7ft and 7.3ft respectively

The formula for calculating the volume of the chocolate bar is expressed as:

  • V = Base area * height

Given the following parameters

  • Base area = 48.96 square feet
  • B = length * width
  • 48.96 square feet = lw

If the length is 0.6 foot shorter than twice its width, hence;

l = w - 0.6

The expression becomes;

48.96 = w(w-0.6)\n48.96 = w^2 - 0.6w\nw^2 - 0.6w - 48.96 - 0

On factorizing the result, w = 7.3ft

Recall that l = w - 0.6

l = 7.3 - 0.6

l = 6.7ft

Hence the length and the width of the bar are 6.7ft and 7.3ft respectively.

Answer:

Length=9.6

Width=5.1

Step-by-step explanation:

Step one:

given data

for the large chocolate

Area=48.96ft^2

let the width be x

w=xft

let the length be l

l=(2x-0.6)

Step two:

we know that area A=length * width

48.96=(2x-0.6)*x

48.96=2x^2-0.6x

2x^2-0.6x-48.96=0

divide through by 2 we have

x^2-0.3x-24.48=0

solving the quadratic equation, the roots are

x=5.1

x=-4.8-----not correct cannot be -ve

so x=5.1

the width is 5.1

the length = 2(5.1)-0.6

l=10.2-0.6

l=9.6

check Area= 9.6*5.1= 48.96

Given a conditional statement p → q, which statement is logically equivalent? ~p → ~q
~q → ~p
q → p
p → ~q

Answers

Hello,
p=>q  is equivalent to ~q → ~p


p-------q-------p=>q--~q ----- ~p----~q → ~p
0-------0-------1-------1 ------- 1------- 1
0-------1-------1-------0-------  1------- 1
1-------0-------0-------1-------  0-------0
1-------1-------1-------0-------  0-------1

Column 3= column 6 ==>equivalent


Answer B

The logically equivalent statement to p → q is:

~q → ~p

How to find the logically equivalent statement?

The conditional statement:

p → q

p and q are propositions, then the conditional statement is can be written as:

  • if p is true, then q is also true.

So, always that p is true, q is also true, this means that if q is not true, then p must also not be true.

Then we can rewrite this using the negation propositions, which are:

~p  and ~q

These mean:

Not p and Not q respectively.

Then the statement:

"If q is not true, then p is not true"

Is written as:

~q → ~p

So this is the logically equivalent statement.

What is the next term in the sequence 2, 8, 32, 128, ...? 256 512 768 1024

Answers

The next term in the sequence would be 512.

In order to find the next term, you need to find out what the relation between one term is to the next.

Start by dividing each number by the one before it to see if they have a common divisor:

8/2 = 4

32 / 8 = 4

128 / 32 = 4

The relationship therefore, is that the next term is simply acquired by multiplying the previous term by 4.

The next term would therefore be:

= Last term x 4

= 128 x 4

= 512

In conclusion, the next term in this sequence is 512.

Find out more at brainly.com/question/10716800.
the next term is 512, because each term is multiplied by 4 

2x4=8
8x4=32
32x4=128
128x4=512 etc..

How do I write 4(3x+2)-9 in written form?

Answers

Step-by-step explanation:

4 times 3x+2 subtracted by9

hope it helps

stay safe healthy and happy.

Answer:

12x-1

Step-by-step explanation:

First, you would have to distribute. Would mean to multiply the 4 with every number in the parenthesis.

4(3x+2)-9

12x+8-9

Now combine like terms

8-9 = -1

The answer is 12x-1
