Answer:

64

Step-by-step explanation:

its subtracting the square of the numbers

169-7²= 120

120-6²=84

84-5²=59

59-4²=43

43-3²=34

34-2²=30

so the sum is 64

Responder:

24 litros; 16 litros; 4 litros

Explicación paso a paso:

Dado que:

Gasolina consumida = 20 litros

Sea la cantidad de gasolina en el tanque = x

Primera parte del viaje = 2/3 de x

Segunda parte del viaje = 1/2 de (x - 2x / 3)

Cantidad de gasolina en el tanque:

2x / 3 + 1/2 (x - 2x / 3) = 20

Solución para x

2x / 3 + x / 2 - x / 3 = 20

(4x + 3x - 2x) / 6 = 20

5 veces / 6 = 20

5 veces = 20 * 6

5 veces = 120

x = 120/5

x = 24

Cantidad de gasolina en el tanque = 24 litros

Litros consumidos en cada etapa:

Primera parte = 2/3 de 24 = 48/3 = 16 litros

2a parte = 0.5 de (24 - 16) = 0.5 * 8 = 4 litros

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

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%.

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:

∠TAR =  35°

Step-by-step explanation:

∠TAR = ∠CAR - ∠CAT = (9x + 7) - 5x = 4x + 7

AT bisect ∠CAR       ∠TAR = ∠CAT

4x + 7 = 5x

x = 7

∠TAR = 4 x 7 + 7 = 35

Answer:

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
