An engineer is designing an arch-shape gate for the entrance to an amusement park. The gate must be 80 feet wide and 25 feet tall what will be the equation of the parabolic shape of the gate Answers:
X^2=-16(y-25)
(X-16)^2=-4(y-25)
X^2=-64(y-25)
(X-25)^2=-16(y-16)
X^2=-40(y-25)

your answer is a

step-by-step explanation:

4*4*4*4=256

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

n=9

step-by-step explanation:

7 times a number = 7n

decreased by 13 = 7n-13

same as is =

5 times the number = 5n

increased by 5 = 5n+5

7n-13 = 5n+5

2n=18

n=9
