Hi! The total cost of this circus trip for the family would be 41 or $41.

Step-by-step explanation:

If you add 7+3 to get the total amount 1 ticket for 1 adult would be, it would be 10. So 10+10 for both adult tickets would be $20.  3 child tickets would cost $21 (7x3 or 7+7+7). Last, you would add up 20+21 and would get 41 and just add the dollar sign in front.

Hope this helps! Have a good day!

X = number of adult tickets
7x = value of the adult tickets

3x = number of child tickets
3x * 3 = value of children's tickets, which is also 9x

Value of adults plus value of children's = 6000

7x + 9x = 6000
Combine terms
16x = 6000
Divide by 16
x = 6000/16
Simplify fraction
x = 3000/8 = 1500/4 = 750/2 = 375 = number of adult tickets

Number of children's tickets = 3 * 375 = 1125 = number of children's tickets

Check:
Adults = 375 * 7 = 2625
Children's = 1125 * 3 = 3375
Total = 6000

valentina_108 [34]

Answer: 87.7^{\circ}


Step-by-step explanation:

Height of the building AB= 443 meters

Distance between the building and the agent at the ground BC= 18 meters

Let x be the angle the agent should shoot his laser gun

Since ΔABC is a right triangle, then

\tan\ x=\frac{AB}{BC}

\Rightarrow\tan\ x=\frac{443}{18}\\\Rightarrow\tan\ x=24.6111\\\Rightarrow\ x=\tan^{-1}(24.61)\\\Rightarrow\ x=87.67^{\circ}\approx87.7^{\circ}

Aleksandr [31]

Answer:

5

Step-by-step explanation:

for the first gear

revolutions/teeth

1 / 24

2 / 48

3 / 72

4 / 96

5 / 120

6 / 144

for the second gear

revolutions/teeth

1 / 40

2 / 80

3 / 120

4 / 160

<em>the two marks will meet after 120 teeth, 5 revolutions of the first gear and 3 revolutions of the second.</em>

the way to get that amount of teeth is

24 = 2 \times 2 \times 2 \times 3 =  {2}^{3}  \times 3

40 = 2 \times 2 \times 2 \times 5 =   {2}^{3}  \times 5

the Least Common Multiple equals the product of all factors, but those factors who are repeted for both numbers should be only once.

{2}^{3} \times 5 \times 3 = 120

120 teeth are 5 revolutions for gear1 and 3 por gear2

u₁₂ represents the amount of loan remaining after 12 years

<h3>How to interpret u₁₂?</h3>

The function is given as:

u₀ = 8000

u_n = u_{n-1}(1 + 0.054) - 500

Given that the subscript n in u_n represents number of years and u_n represents the amount left to be paid after n years.

We can conclude that:

u₁₂ represents the amount of loan remaining after 12 years
