Tickets to a concert cost $2 for children, $3 for teenagers and $5 for adults. When 570 people attended the concert, the total t

Ilia_Sergeevich [38]

Answer: 220

Step-by-step explanation:

Children (x): $2

Teens (y): $3, $\frac{3}{4}x$

Adults: (z): $5

Quantity: x + y + z = 570 ⇒ x + $\frac{3}{4}x$ + z = 570 ⇒ 1.75x + z = 570

Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3 $(\frac{3}{4}x)$ + 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950

Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850

Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → -4.25x - 5z = -1950

4.50x = 900

x = 200

Teens (y): $\frac{3}{4}x$

y = $\frac{3}{4}(200)$

= $\frac{600}{4}$

= 150

Quantity: x + y + z = 570

200 + 150 + z = 570

350 + z = 570

z = 220

A right rectangular prism has a length of 8 centimeters, a width of 3 centimeters, and a height of 5 centimeters. What is the su

ladessa [460]

Answer: $158cm^2$

Step-by-step explanation:

You can use the following formula to calculate the surface area of the right rectangular prism:

$SA = 2(wl +lh + hw)$

Where "w" is the width, "l" is the length, and "h" is the height.

Knowing that this rigth rectangular prism has a length of 8 centimeters, a width of 3 centimeters and a height of 5 centimeters, you can substitute these values into the formula.

Then, the surface of the right rectangular prism is:

$SA = 2[(3cm*8cm) + (8cm*5cm) + (5cm*3cm)]\\\\SA=158cm^2$

Juan is determining the volume of a box using the expression 7.2*8.4*12.8 how many digits will be shown to the right of the deci

beks73 [17]

Answer:

Juan will have 3 digits after decimal.

Step-by-step explanation:

A number having one digit after decimal when multiplied by another number having single digit after decimal, we get a number having two digits after decimal.

Example:

0.2 × 0.6 = 0.12

0.3 × 0.3 = 0.09

Now we have to find the volume of a box having dimensions 7.2 units by 8.4 units by 12.8 units.

Volume = 7.2×8.4×12.8 [Each number having one digit after decimal]

= 774.144 unit³ [Number with 3 digits after decimal]

Therefore, Juan will have 3 digits after decimal in the final answer.
