There are two expressions
Price of video games: 4(25) = $100
Sale tax: 0.06(100) = $6
Total: $100 + $6 = $106
Answer:
The height of the wall is 9.17ft
Step-by-step explanation:
The length of the ladder is 10ft
Distance from the foot of the ladder to the wall is 4ft
The height of ladder is unknown.
To solve this question, you'll require a pictorial illustration of the situation. Kindly check attached document for that.
Since it's a right angle triangle, we have two sides with one sides unknown, we can use pythagorean theorem to find the third side.
The hypothenus (x) is 10ft
The adjacent is (y) 4 ft
The opposite (z) (height of the wall) is unknown.
X² = Y² + Z²
10² = 4² + Z²
100 = 16 + Z²
Z² = 100 - 16
Z² = 84
Z = √(84)
Z = 9.165 = 9.17ft
The height of the wall is 9.17ft
The new model is 11/40 of an inch thinner than the old model.
In order to do this, we need to subtract the new model from the old model.
7/8 - 3/5
In order to complete this, we will need common denominators.
35/40 - 24/40
Then simply complete the operation.
11/40
