Answer:
100
Step-by-step explanation:
20/2= 10 and 10 squared is 100 but you have to move the -6 to the opposite side
Answer:
1,737.3 feet
Step-by-step explanation:
Let's assume the length of the bridge consists of 2 right triangles as shown in the diagram. Use pythagorean theorem to find the other missing leg of each right triangle.
Let the missing leg for each triangle be x and y respectively.
Length of bridge = x + y
✔️x = √(1115² - 860²) = √503,625
x ≈ 709.7 (nearest tenth)
✔️y = √(1340² - 860²)
y ≈ 1,027.6 (nearest tenth)
✔️ Length of bridge = 709.7 + 1,027.6 = 1,737.3 ft
Answer:
2nd number = 13
First number = 15
3rd number = 30
Step-by-step explanation:
Let
2nd number = 1/2x - 2
First number = 1/2x
3rd number = x
Total = 58
x + 1/2x + 1/2x - 2 = 58
x + x+x/2 = 58 + 2
x + 2/2x = 60
x + x = 60
2x = 60
x = 60/2
= 30
x = 30
2nd number = 1/2x - 2
= 1/2*30 - 2
= 15 - 2
= 13
First number = 1/2x
= 1/2*30
= 15
3rd number = x
= 30
You plug in the numbers listed under x into the equation, and it will give you your y value:
x is 3
y = 4(3)
y = 12
x is 4
y = 4(4)
y = 16
x is 5
y = 4(5)
y = 20
Answer:
y>=x+1
Step-by-step explanation:
it will be y>= x+1 bcz the shaded area shows a straight line rather than a dotted line which means the line is part of the shaded region. so that's why y>=x+1
