Answer:
what's your question though?
Let the amount of adult tickets sold be x
Since the total of 380 tickets sold consists of the amount of adult tickets and the amount of children tickets that are 70 fewer:
x + (x - 70) = 380
2x - 70 =380
2x = 450
x = 225
Therefore, the amount of adult tickets sold is 225
Answer:
- 5.9%
Step-by-step explanation:
Data provided in the question :
Future value of the amount invested = $4,600
Principle i.e amount of purchase = $7,500
Time, n = 8 years
Now,
let the interest rate be 'i'
using compounding
$4,600 = $7,500 × (1 + i)⁸
or
0.613 = (1 + i)⁸
or
1 + i = 0.941
or
i = -0.059
or
interest rate = - 5.9%
Here negative sign means loss
Answer:
b= 26
Step-by-step explanation:
there are 2 triangles
area of the right angles triangle
1/2bh= 1/2 x3 x4 = 6cm²
for the next triangle we use pythagoras theorem to calculate the height
3²+4² = h² = 9+16 = 25
h = √25 =5
1/2bh = 1/2 x 5 x8 = 20
adding the two areas will give the area of the figure = 20 + 6 = 26
