Answer:
$615.54
Step-by-step explanation:
Step 1
Write your problem.
577.98 x 6.5% = ?
Step 2
Convert the % to a decimal:
6.5% to 0.065
Step 3
Rewrite the problem with decimal replacing the percentage.
Now the problem looks like this:
577.98 x 0.065 = 37.56
This problem gives the amount of the tax.
Step 4
Add the original price with the tax amount:
577.98 + 37.56 = $615.54 (total cost)
Multiply $115.74 by .7 (.7 = 70%) then add that to $115.74 to get the total.
The length of SR is 10 inches ⇒ answer B
Step-by-step explanation:
The median of a triangle is the segment drawn from one vertex to
the mid-point of the opposite side to this vertex
In Δ PQR
1. QS is a median
2. RT is a median
We need to find the length of SR
∵ QS is a median in Δ PQR
∵ PR is the opposite side to vertex Q
∴ S is the mid-point PR
∴ PS = SR
∵ PS = 4x - 2
∵ SR = 2x + 4
∴ 4x - 2 = 2x + 4
- Subtract 2x from both sides
∴ 2x - 2 = 4
- Add 2 to both sides
∴ 2x = 6
- Divide both sides by 2
∴ x = 3
Substitute the value of x in the expression of SR
∵ SR = 2x + 4
∵ x = 3
∴ SR = 2(3) + 4
∴ SR = 6 + 4
∴ SR = 10 inches
The length of SR is 10 inches
