The formula for the area of a triangle is A=1/2bh
Solve the formula for h (Hint: isolate h.)
To solve the formula for h, we need to isolate h on one side of the equation.
Given formula: A = 1/2bh
Step 1: Multiply both sides of the equation by 2 to eliminate the fraction.
2A = bh
Step 2: Divide both sides of the equation by b to isolate h.
(2A)/b = h
Therefore, the formula for h (height) in terms of the area A and base b of a triangle is h = (2A)/b.
A triangle has a base of 7cm and an area of 28cm^2. What is its height?
To find the height of the triangle, we can use the formula we derived earlier:
h = (2A)/b
Given that the base (b) of the triangle is 7cm and the area (A) is 28cm^2, we can substitute these values into the formula:
h = (2(28cm^2))/(7cm)
h = (56cm^2)/(7cm)
h = 8cm
Therefore, the height of the triangle is 8cm.
You work for 4 hours on Saturday and 8 hours on Sunday. You also receive a $50 bonus. You earn $164. How much did you earn per hour?
To find out how much you earned per hour, we need to divide your total earnings by the total number of hours worked.
Let's calculate the total number of hours worked:
Total hours = hours worked on Saturday + hours worked on Sunday
Total hours = 4 hours + 8 hours
Total hours = 12 hours
Now, let's calculate your earnings per hour:
Earnings per hour = Total earnings / Total hours
Earnings per hour = $164 + $50 / 12 hours
Earnings per hour = $214 / 12 hours
Earnings per hour = $17.83 per hour
Therefore, you earned approximately $17.83 per hour.
To solve the formula A = 1/2bh for h, we need to isolate the variable h on one side of the equation. Here's how you can do it step-by-step:
Step 1: Start with the given formula: A = 1/2bh.
Step 2: Multiply both sides of the equation by 2 to eliminate the fraction: 2A = bh.
Step 3: Divide both sides of the equation by b: 2A/b = h.
Therefore, the formula can be solved for h as h = 2A/b.
To solve the formula A = 1/2bh for h, we need to isolate h.
Step 1: Start with the formula A = 1/2bh.
Step 2: Multiply both sides of the equation by 2 to eliminate the fraction: 2A = bh.
Step 3: Divide both sides of the equation by b to isolate h: (2A)/b = h.
So, the formula for h is h = (2A)/b.
To solve for h, you can substitute the given values for A and b into the formula.
