If 2c - 5 = 3d + 4, what does c equal, in terms of d?
Answers
Answer:
D. [tex]\frac{3d+9}{2}[/tex]
Step-by-step explanation:
2c - 5 = 3d + 4
Isolate 2c.
2c = 3d + 4 + 5
Simplify.
2c = 3d + 9
(2c ÷ 2 = c) Find c.
c = [tex]\frac{3d+9}{2}[/tex]
Answer:
[tex]d. \: \frac{3d + 9}{2} [/tex]
Step-by-step explanation:
Follow the steps below.
[tex]2c - 5 = 3d + 4 \\ 2c = 3d + 9 \\ c = \frac{3}{2} d + \frac{9}{2} \: or \: c = \frac{3d + 9}{2} [/tex]
So D is correct.
Toni gets paid $30 to rake a lawn. The mean man who hired her deducts $3 from her wage for every 2 leaves that are still left on the lawn when she finishes the job. How many leaves does the mean man have to see left on the ground before Toni goes home with no money?
Answers
Answer:
20 leaves
Step-by-step explanation:
Step one:
given data
we are told that the amount paid =$30
The mean man deducts $3 for every 2 leaves seen on the lawn.
we are expected to estimate the number of leaves that can amount to a $30 deduction.
Step two:
let the number of leaves be x
so if 2 leaves are worth $3 deductible
the x leave will worth $30 deductible
cross multiply we have
x=30*2/3
x=60/3
x=20 leaves

A 10.0kg cart traveling East at 5.00 m/s collides with a 7.50kg cart traveling 3.00m/s at an angle of 55.0o. The two carts collide and stick together. What is the velocity of the cars after they stick together?
Answers
Answer:
The magnitude of the velocity of the cars after they stick is approximately 3.7 m/s
Step-by-step explanation:
The given parameters are;
The mass of the cart traveling East, m₁ = 10.0 kg
The speed of the cart traveling East v₁= 5.00 m/s
The mass of the cart traveling at an angle of 55° m₂= 7.50 kg
The speed of the cart traveling at an angle of 55°, v₂ = 3.00 m/s
The component of the velocities of the cart raveling at an angle are given as follows;
v = 3.00 × cos(55°)·i + 3.00 × sin(55°)·j
The total momentum before collision = m₁ × v₁ + m₂ × v₂ by substitution is therefore;
m₁ × v₁ + m₂ × v₂ = 10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j)
The total momentum after collision = (m₁ + m₂) × v₃
By the principle of the conservation of linear momentum, whereby the momentum is conserved, we have;
m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃
10 × 5.00·i + 7.5 × (3.00 × cos(55°)·i + 3.00 × sin(55°)·j) = (10 + 7.5) × v₃
50.00·i + 12.91·i + 18.43·j = 17.5·v₃
62.91·i + 18.43·j = 17.5·v₃
∴ v₃ = (62.91·i + 18.43·j)/17.5 ≈ 3.59·i + 1.05·j
Therefore, the magnitude of the velocity of the cars after they stick = √(3.59² + 1.053²) ≈ 3.7
The magnitude of the velocity of the cars after they stick ≈ 3.7 m/s.
