Answer:
y=96
Step-by-step explanation:
Important information:
y=x^2(2+4)
x=4
Explanation/Solution:
y=x^2(2+4)
y=4^2(2+4)
y=16 (2+4)
y= 16 · 6 =
y=96

Answer:
Number of children = 386
Number of adults = 287
Step-by-step explanation:
Let
x = number of children
y = number of adults
x + y = 673 (1)
1.75x + 2y = 1249.50 (2)
From (1)
x = 673 - y
Substitute x = 673 - y into (2)
1.75x + 2y = 1249.50
1.75(673 - y) + 2y = 1249.50
1177.75 - 1.75y + 2y = 1249.50
- 1.75y + 2y = 1249.50 - 1177.75
0.25y = 71.75
y = 71.75/0.25
y = 287
Substitute y = 287 into (1)
x + y = 673
x + 287 = 673
x = 673 - 287
x = 386
Number of children = 386
Number of adults = 287
Answer:
3x+12
Step-by-step explanation:
Triple is 3 times a number which we will call “x” and sonce it is the sum, it is addition :)
The length of the arc is 4π.
<u>Step-by-step explanation</u>:
Given,
- Diameter = 24 ft
- radius, r = diameter/2
- r = 24/2 = 12 ft
- central angle, ∅ = 60°
Arc length = ∅/360° (2πr)
⇒ 60°/360° (2π
12)
⇒ 24π/6
⇒ 4π
∴ The length of the arc is 4π.
