ANEK [815]

Answer:

Yes, Ayden meet his goal.

Step-by-step explanation:

Given:

Total square meters of house's wall Ayden had to paint = 500 square meters.

The percent of goal Ayden had for painting the wall = 80%.

The square meters of wall Ayden finished painting = 415 square meters.

Now, to find whether Ayden meet his goal.

So, to get the square meters of wall Ayden had the goal:

$80\%\ of\ 500\\\\=\frac{80}{100}\times 500\\\\=0.80\times 500\\\\=400\ square\ meters.$

Thus, the goal Ayden had was to paint 400 square meters of wall.

And, he actually finished 415 square meters of wall.

So, the square meters of wall Ayden had finished painting is more than his goal to achieve.

Hence, Ayden meet his goal.

Therefore, yes, Ayden meet his goal.

The amount of money in Nadia’s savings account is represented by the recursive formula an=1.025(an-1)+50 if a6=291.51 what are t

Elis [28]

Recursive formula is one way of solving an arithmetic sequence. It contains the initial term of a sequence and the implementing rule that serve as a pattern in finding the next terms. In the problem given, the 6th term is provided, therefore we can solve for the initial term in reverse. To make use of it, instead of multiplying 1.025, we should divide it after deducting 50 (which supposedly is added).

Therefore, we perform the given formula: A (n) = 1.025(an-1) + 50
a(5) =1.025 (235.62) + 50 = 291.51

a(4) = 1.025 (181.09) + 50 = 235.62

a(3) = 1.025 (127.89) + 50 = 181.09

a(2) = 1.025 (75.99) + 50 = 127.89

a(1) = 1.025 (25.36) + 50 = 75.99

a(n) = 25.36

The terms before a(6) are indicated above, since a(6) is already given.

So, the correct answer is A. $25.36, $75.99.

Al's Awesome Autos advertised a special sale on cars - Dealer cost plus 5%!! Jack and Margaret ought a luxury sedan for $23,727.

Alex17521 [72]

105/23727.90=100/x
105x=23727.90x100
105x=2372790
(105x)/105=2372790/105
x=22598

dealers cost is $22,598

the 105% is the 100% price of the car plus the 5% of that tax or whatever it is
