She says 35 because number 7 in line says 31, so 31+4=35...
I hope this helped you!
Answer: See explanation
Step-by-step explanation:
The perimeter of a pentagon is gotten through the summation of its five sides. Let the first side be represented by x. Since each side of a pentagon is 10 cm greater than the previous side, then the sides will be:
First side = x
Second side = x + 10
Third side = x + 10 + 10 = x + 20
Forth side = x + 30
Fifty side = x + 40
Therefore,
x + (x + 10) + (x + 20) + (x + 30) + (x + 40) = 500
5x + 100 = 500
5x = 500 - 100
5x = 400
x = 400/5
x = 80
Therefore, the lengths will be:
First side = x = 80cm
Second side = x + 10 = 80 + 10 = 90cm
Third side = x + 20 = 80 + 20 = 100cm
Forth side = x + 30 = 80 + 30 = 110cm
Fifty side = x + 40 = 80 + 40 = 120cm
Answer:
It would be worth $5,040 after 7 years
Step-by-step explanation:
Multiply 40% by 7 and get 280, then turn it into a percent, .280, finally multiply it by $18,000 to get $5,040
The y-intercept is 0 because you can add it to the equation and it won't change your slope.
The height of your scale model will be 37.8cm.
1.26 x 30
