A painter has a 24 foot ladder that he is using to paint a house. For safety reasons, the ladder must be placed at least 8 feet
Lana71 [14]

Answer:

The ladder can reach a height of 22.6 feet.  

Step-by-step explanation:

In order to find the height that the ladder can reach, you need to use the Pythagorean Theorem.  The Pythagorean Theorem assumes that the house to the ground will form a right triangle and the leaning ladder is the hypotenuse.  Using the formula:  a² + b² = c², we can plug in the values that we know and solve for the missing variable.  In this case we know the base of the triangle 'b' and the hypotenuse 'c':  a² + 8² = 24² or a² + 64 = 576.  To solve for a, we must first subtract 64 from both sides:  a² + 64 - 64 = 576 - 64 or a² = 512.  In order to find just the value of 'a', which represents the height, we need to take the square root of both sides:  √a² = √512 or a ≈ 22.6 feet.

a family had dinner in a restaurant and paid rs 900 for food they also had to pay 1p percent sale tax and 15 percent for the tri
jarptica [38.1K]

Answer:

Total amount pay for dinner = Rs 1,014

Step-by-step explanation:

Given:

Amount pay for food = Rs 900

Percentage of sales tax = 1%

Percentage of trip payment = 15%

Find:

Total amount pay for dinner

Computation:

Amount pay for sales tax = Amount pay for food x Percentage of sales tax

Amount pay for sales tax = 900 x 1%

Amount pay for sales tax = 900 x 0.01

Amount pay for sales tax = Rs 9

Amount pay for trip = Amount pay for food x Percentage of trip payment

Amount pay for trip = 900 x 15%

Amount pay for trip = 900 x 0.15

Amount pay for trip = Rs 105

Total amount pay for dinner = Amount pay for food + Amount pay for sales tax + Amount pay for trip  

Total amount pay for dinner = 900 + 105 + 9

Total amount pay for dinner = Rs 1,014
