The first term in a sequence of numbers is 1/2

Mathematics
1 answer:
Andrei [34K]3 years ago
7 0

Answer:

The correct answer is C. The 4th term is 11.

Step-by-step explanation:

Since the next term is one more than twice the previous, we can calculate it by the following expression:

a_{n} = 2*a_{n-1} + 1

So the second term is:

a_2 = 2*\frac{1}{2} + 1\\a_2 = 2

The third term:

a_3 = 2*2 + 1\\a_3 = 5

And the fourth term:

a_4 = 2*5 + 1\\a_4 = 10 + 1 = 11

The correct answer is C. The 4th term is 11.

Write 2 equivalent ratios for each ratio given:<br> 2/7<br> 3:3 1/2<br><br> 2.5 to 6
goldenfox [79]

Answer:

2/7 = 4/14

3:3 = 6:6

1/2 = 2/4

2.5:6 = 5:12

For the first one, we can multiply the numerator and denominator of the fraction by 2 to get an equivalent fraction which is 4/14

For the second one we can multiply each side by 2 to get the ratio of 6:6

For the third one we can multiply the numerator and denominator by 2 to get 2/4

For the last one we can multiply each side by 2 to get 5:12

Macy’s buys a pair of Cole Haan dress shoes wholesale for $90. If Macy’s marks up the price 20%, and tax is 9%, how much did Nor
stich3 [128]

Answer:

Norman bought the shoes for $117.72

Step-by-step explanation:

In order to find the answer to this question, start by multiplying the cost by the markup.

$90 * 20% = $18.

Now we add the $18 to the original price.

$90 + $18 = $108

Now that we have the mark up price, we need to do the same using the tax.

$108 * 9% = $9.72

Finally, we add that to the previous total.

$108 + $9.72 = $117.72
