Answer:

First/Top graph.

Step-by-step explanation:

First, we need to solve the inequality for n:

-6n + 5 < 11 (Given)

-6n < 6 (Subtracted 5 on both sides)

n > -1 (Divided -6 on both sides)

NOTE: Whenever you multiply or divide by a negative number when dealing with inequalities, the sign switches.

Now that we know that n > -1, we need to look for a graph that has an open circle on the point -1 and goes in the right direction.

Therefore, the first graph is the correct answer.

Answer:

90

Step-by-step explanation:

Given that :

Number of soldiers = 8160

Number left out = 60

Result of arrangement gives a perfect square ;

Hence, the number of soldiers which makes up the arrangement will be ;

Total number of soldiers - number left out

8160 - 60 = 8100

Hence 8100 soldiers were used to form a perfect square ;

Number of soldiers in a row :

√8100 = 90

Hence, we have 90 soldiers in a row

Answer:

x= 12°

Step-by-step explanation:

The angle measures in the triangle are given as;

A = 4x  

B= 5x

C= 6x

The sum of angle measures in a triangle add up to 180°

Applying the statement in an equation as;

4x + 5x + 6x = 180°

15x = 180°

x= 180° / 15

x = 12°

Answer:

El camión lleva 3000 cajas de patatas

Step-by-step explanation:

Proporciones

La capacidad de carga de un camión es de 68.25 Toneladas de patatas.

Como 1 tonelada es equivalente a 1000 Kg, expresamos la capacidad en Kg:

68.25 * 1000 = 68250 Kg

Cada caja de patatas pesa 22.75 Kg, luego el número de cajas que caben en el camión son:

68250/22.75 = 3000 cajas

El camión lleva 3000 cajas de patatas

Answer:

[tex]G(x) = 2x^2+6[/tex].

Step-by-step explanation:

The given function is

[tex]f(x) = \frac 2 3 x^2 +2[/tex]

On vertical stretch by a factor of 3, the new function G(x) is

G(x) = 3 f(x)

So, [tex]G(x) = 3 \times ( \frac 2 3 x^2 +2)= 2x^2+6[/tex]

Hence, the required function is [tex]G(x) = 2x^2+6[/tex].

Answer:

18

Step-by-step explanation:

If you want to give people something, you need to divide the number that she is sharing (75) and the number of how many people she is sharing with (4).

So 75/4 = 18

So 18 marshminnows are left for Gracie.

Note that x and y are nonzero integers. It means that x and y will always have same sign (both are either positive or negative, since they are nonzero). Hence, xy term is always positive.

Answer:

No, if y happens to be a larger integer than x, then the result will be negative.  

Step-by-step explanation:

For example, lets say that x=4 and y=9, so x-y = 4-9 = -5.  

But if we were to reverse it and make x=9 and y=4, then x-y = 9-4 = 5.

Answer:

[tex]T_n=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]

Step-by-step explanation:

nth term of an A.P. is given by the explicit formula,

[tex]T_n=a+(n-1)d[/tex]

Here, 'a' = First term

n = number of term

d = common difference

For an A.P. given as,

[tex]\text{log}_a(54),\text{log}_a(18),\text{log}_a(6),....[/tex]

First term 'a' of the given A.P. = [tex]\text{log}_a(54),[/tex]

Common difference 'd' = [tex]T_2-T_1[/tex]

                                       = [tex]\text{log}_a(18)-\text{log}_a(54)[/tex]

                                       = [tex]\text{log}_a(\frac{18}{54})[/tex]

                                       = [tex]\text{log}_a(\frac{1}{3})[/tex]

                                       = [tex]-\text{log}_a(3)[/tex]

[tex]T_n=\text{log}_a(54)+(n-1)[-\text{log}_a(3)][/tex]

    [tex]=\text{log}_a(54)-(n-1)\text{log}_a(3)[/tex]

    [tex]=\text{log}_a(3^3\times 2)-(n-1)\text{log}_a(3)[/tex]

    [tex]=\text{log}_a(3^3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]

    [tex]=3\text{log}_a(3)+\text{log}_a(2)-(n-1)\text{log}_a(3)[/tex]

    [tex]=3\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)+\text{log}_a(3)[/tex]

    [tex]=4\text{log}_a(3)+\text{log}_a(2)-n\text{log}_a(3)[/tex]

    [tex]=(4-n)\text{log}_a(3)+\text{log}_a(2)[/tex]

Answer:

7.3 or 7 hours.

Step-by-step explanation:

So i divided 58.4 by 8. And got 7.3.

8 x (7) = 56. So, 58 - 56 = 2. Put the decimal up. Now, 8 x (3) = 24. So, now you should have 7.3. But you could round it to 7. Depends.

Answer:

the unit price that required is $30.60

Step-by-step explanation:

The computation of the unit price that required is shown below

For one mile, the cost is

= taxi ride cost ÷ distance covered

= $50.40 ÷ 56

= $0.90

Now for the cost of 34 mile taxi ride

= Unit cost × distance covered

= $0.90 × 34 mile

= $30.60

hence, the unit price that required is $30.60

We simply applied the above formula so that the correct cost could come

The same is to be considered

Answer:

20cm

Step-by-step explanation:

for the triangle:

Perimeter = 30cm

a + a + a = 30

3a = 30

hence a = 10cm

For the rectangle:

Perimeter = 30cm

a + a + b + b = 30

but a = 10cm

10 + 10 + b + b = 30

20 + 2b = 30

2b = 10

hence b = 5cm

Perimeter of square = b + b + b + b

= 5 + 5 + 5 + 5 = 20cm

Complete Question

The average weight of A, B and C is 45 kg. If the average weight of A and B be 40 kg and that of B and C be 43 kg, then the weight of B is :

Answer:

31 kg

Step-by-step explanation:

From the above question:

A ,B and C average is 45.

Hence, the total values of A, B, C is calculated as:

A + B + C /3 = 45

A + B + C = 45 × 3

A + B + C = 135

Also,

B and C average is 43

The total values of B, C is calculated as:

B + C /2 = 43

B + C = 43 × 2

B + C = 86

A and B average is 40

The total values of A, B is calculated as:

A + B /2 = 40

A + B = 40 × 2

A + B = 80

Hence:

A + B + C = 135

B + C = 86

A + B = 80

Hence, we can solve for A, we substitute 80 for A + B

80 + C = 135

C = 135 - 80

C = 55kg

B + C = 86

B + 55 = 86

B = 86 - 55

B = 31 kg

Answer:

37.5%

Step-by-step explanation:

OOF DIS COMPLICATED

I messed up big timeeeeeeeee

A lot of percent problem are very simple by just assuming values, especially in case the answer is also a percentage.

If there are 100 birds, 20% are tagged so 20 are tagged.

Out of the rest 80, 30 should be tagged so that a total of 50% are tagged.

30/80 = 37.5%

(The huge number given is unnecessary, just to make you waste your valuable time. Read the question again to realize that it is not needed.)

The percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.

First step

Currently Tagged birds= 54210 ×20/100

Currently Tagged birds=10842

Second  step

Untagged birds=54210 - 10842

Untagged birds=43368

Third step

Untagged birds percentage:

Untagged birds percentage=( 54210/2)-10842/43368

Untagged birds percentage=(27105-10842)/43368

Untagged birds percentage=16263/43368

Untagged birds percentage=0.375×100

Untagged birds percentage=37.5%

Inconclusion the percent of the untagged birds that must be tagged so that half of all birds in the refuge are tagged is 37.5%.
