Place the following numbers in ascending order. 20/7, 3.1, 2 3/4 (Answer should be in original form

Answer:

=50

Step-by-step explanation:

The product of (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]) is 50.

The given expression is (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]).

We need to find the product for it.

Simplify the radical by breaking the radicand up into a product of known factors, assuming positive real numbers.

Now,  (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex])=(3+4i)(6-8i)

=18+24i-24i-32i²

=18+32=50 (∵i²=-1)

Hence, the product of (3+[tex]\sqrt{-16}[/tex])(6-[tex]\sqrt{-64}[/tex]) is 50.

Answer:

[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]

Step-by-step explanation:

Geometric Sequences

The geometric sequence is given as:

[tex]a_1, a_1r, a_1r^2, a_1r^3,..., a_1r^{n-1}[/tex]

Where n is the number of the term, n≥1, and r is the common ratio.

The sum of n terms of the geometric sequence is given by:

[tex]\displaystyle S_n=a_1\frac{r^n-1}{r-1}[/tex]

We are given: S3=252, a1=192, thus substuting:

[tex]\displaystyle 252=192\frac{r^3-1}{r-1}[/tex]

Dividing by 12:

[tex]\displaystyle 21=16\frac{r^3-1}{r-1}[/tex]

Recall that:

[tex]r^3-1=(r-1)(r^2+r+1)[/tex]

Substituting:

[tex]\displaystyle 21=16\frac{(r-1)(r^2+r+1)}{r-1}[/tex]

Simplifying:

[tex]21=16(r^2+r+1)=16r^2+16r+16[/tex]

Rearranging:

[tex]16r^2+16r+16-21=0[/tex]

16r^2+16r-5=0

Rewriting:

[tex]16r^2-4r+20r-5=0[/tex]

Factoring:

[tex]4r(4r-1)+5(4r-1)=0[/tex]

[tex](4r-1)(4r+5)=0[/tex]

Solving:

[tex]r=\frac{1}{4}\\\\r=-\frac{5}{4}[/tex]

Both solutions are valid

Answer:

  25 tables, 5 desks, for a profit of $115

Step-by-step explanation:

Let x and y represent the numbers of tables and desks to build, respectively. The we want to maximize 4x+3y subject to the constraints ...

  x +3y ≤ 45 . . . . . constraint on labor

  10x +20y ≤ 350 . . . . . constraint on wood

 2x +y ≤ 55 . . . . . constraint on finish

These inequalities are graphed in the attachment. The vertex of the feasible region that maximizes profit is (x, y) = (25, 5).

The product mix that maximizes profit is ...

  25 tables

  5 desks

for a profit of 25·4 +5·3 = 115 dollars.

Answer:

You have a 50% chance of picking a multiple of 3.

Step-by-step explanation:

If we include 1 and 24 as factors of 24, then the possible choices would be:

1, 2, 3, 4, 6, 8, 12, 24

Of those, the only ones that are multiples of 3 are 3, 6, 12 and 24.  Meaning that the chance of getting a multiple of 3 is 4/8, or 1/2, i.e. 50%

If we don't include 1 and 23, then we have:

2, 3, 4, 6, 8, 12

and 3, 6 and 12 are divisible by 3.

Which again gives 1/2, or 50%

So regardless of whether 1 and 24 are included, the chance of picking a multiple of three from the factors of 24 is 50%.

follow a few exponent rules and you can figure this out

when expoenents are to the power of something you can mutilply the expoents.. and when there is a minus sign in the exponent.. it's like the reciprocal   [tex]x^{-2}[/tex]  is  1/[tex]x^{2}[/tex]    soooo...

mutilply the  -2/3 by each of the exponents in the question the 8 is tricky b/c it has an invisible 1 on it :o

= [tex]8^{-2/3}[/tex][tex]w^{-14/3}[/tex][tex]x^{10/3}[/tex][tex]y^{-6/3}[/tex][tex]z^{18/3}[/tex]

Answer:

The capacity of each bottle is 5.45 of waters or 5 L 450 ML of water

Step-by-step explanation:

We are told that:

Naina emptied a tank holding 65 L 400 ML of water into 12 bottles.

We have 65 Liters and 400ml , we convert everything to Liters

1000ml = 1 L

400ml = x L

Cross Multiply

1000 × x = 400 × 1 L

x = 400/1000

x = 0.4L

Hence, the total capacity of the tank, is 65L + 0.4L = 65.4L

Since there are 12 bottles, we assume that each bottle are of the same size hence, the capacity of each bottle is

calculated as:

12 bottles = 65.4 L

1 bottles = x

Cross Multiply

12x = 65.4L

x = 65.4L /12

x = 5.45 L

Hence, the capacity of each bottle is 5.45 or 5 Liters, 450 ML
