Your cousin renews his apartment lease and pays a new monthly rent. His new rent is calculated by applying a discount of $50 to
nasty-shy [4]

Answer:

  • $1100

Step-by-step explanation:

Let the rent be x

<u>Discounted rent </u>

  • x - $50

<u>Increase applied</u>

  • 10%

<u>Final rent:</u>

  • (x - 50) + 10% = (x - 50)*1.1

<u>We know this is equal to x + 5% = 1.05x, comparing now</u>

  • 1.1(x - 50) = 1.05x
  • 1.1x - 1.05x = 55
  • 0.05x = 55
  • x = 55/0.05
  • x = $1100

The base of the 37 foot ladder is 9 feet from the wall of a building. will the top of the ladder reach a window ledge 35 feet ab
AnnZ [28]

Answer:

The answer to your question is Yes.

Step-by-step explanation:

The math in this problem is that we need to use the Pythagorean theorem to solve it. Pythagorean theorem is part of trigonometry a branch of Maths.

Data

base = 9 ft                      

length = 37 ft

height = ?

Pythagorean theorem

                                     c² = a² + b²

length = c

base = a

height = b

                                   37² = 9² + b²

-Solve for b

                                    b² = 37² - 9²

-Simplify

                                    b² = 1369 - 81

                                    b² = 1288

-Result

                                   b = 35.88

-Conclusion

The ladder will reach a height higher than 35 ft.

spin [16.1K]

Answer: a) 30, b) 120

Step-by-step explanation:

Since we have given that

Let the number of points Scored by Dwayne be 'd'.

Number of points in the last basket ball game = 55 points

According to question, we get that

d+10=55\\\\d=55-10\\\\d=45

Let the number of points that Chris's score be 'c'.

Number of points Lebron scored = 45

According to question, number of points scored by Chris is given by

c+15=45\\\\c=45-15\\\\c=30

a. How many points did Chris score during the game?

c = 30

b. If these are the only three players who scored, what was the team’s total number of points at the end of the game?

45+45+30=90+30\\\\=120

Hence, a) 30, b) 120
