So we add all the amounts together:
250 + 310 + 275 + 195 = 1030
Then we divide by 4 to find the average.
1030/4 = 257.5
The answer is D: $257.50
Hope that helps!
Answer:
D
Step-by-step explanation:
first multiply both sides by 12
collect like terms
x/12×12+3×12<=7×12
x+36<=84
x<=84-36
x<=48
Answer:
x is approximately 226.3 feet
y is approximately 308.6 feet
z is approximately 226.3 feet
Step-by-step explanation:
The given parameters of the walls are;
The angle of elevation from the top of the shorter wall to the top of the opposing wall, θ₁ = 20°
From the diagram, the angle of depression from the top of the shorter wall to the bottom of the opposing wall, θ₂ = 45°
The distance from the bottom of the shorter wall to the base of the opposing wall, l = 320 feet
x = The height of the shorter wall = l × sin(θ₂)
∴ x = 320 feet × sin(45°) = 320 feet × (√2)/2 = 160·√2 feet ≈ 226.3 feet
∴ x ≈ 226.3 feet
By observation, we have;
y = x + z × tan(θ₁)
Where;
z = l × cos(θ₂)
∴ y = 160·√2 + 320 × cos(45°) × tan(20°) ≈ 308.6
y ≈ 308.6 feet
z = l × cos(θ₂)
∴ z = 320 × cos(45°) = 160·√2 ≈ 226.3
z ≈ 226.3 feet.
Answer: The large ____ holds 48 units.
For the diagram you could draw the small rectangle 4 squares wide and 9 squares long. that will represent something that holds 36 units.
For the large one make it 4 squares wide and 12 squares long. That will have spaces for 48 units.
Step-by-step explanation: Change the percent to a decimal and set up the equation that means 36 is 75% of some number, yet unknown, X is the unknown number.
36 = .75x divide both sides by .75
36/.75 = .75x/.75 . The .75 "cancels" on the right. Then use a calculator.
36 ÷ .75 = 48
x = 48
