Answer:

Step-by-step explanation:

x 30%

— = ———

275 100

You can use the butterfly method which combines by multiplication

x*100=100x

Then multiply 275*30

It equals to 8250

Them divide each problem by 100 to get x by itself and the final answer

It makes 30% of 275

82.5

given that a1=5 and a2=15 are the first two terms of a geometric sequence, determine the values of a3 and a10. Show the calculat

Alekssandra [29.7K]

a_3 is 45 and a_10 is 98415

Step-by-step explanation:

Given

a_1 = 5

a_2 = 15

First of all we have to calculate the common ratio of the sequence. The common ratio is the ratio between two consecutive terms of a geometric sequence.

So,

$r=\frac{a_2}{a_1} = \frac{15}{5} = 3$

The explicit formula for geometric sequence is:

$a_n = a_1.r^{n-1}$

Putting the value of r and a_1

$a_n = 5.(3)^{n-1}$

Putting n=3 in the explicit formula

$a_3 =5.3^{3-1}\\= 5 * 3^2\\=5 * 9\\= 45$

Putting n=10 for tenth term

$a_{10} =5.3^{10-1}\\=5*3^9\\=5 * 19683\\=98415$

Hence,

a_3 is 45 and a_10 is 98415

Theo drove 236 miles in 4 hours. Lex drove 195 miles in 3 hours. At those rates, could either man drive 116 miles in 2 hours? Sh

motikmotik

Answer:

No.

Step-by-step explanation:

236÷4=59

195÷3=65

To check if either of them drove 116 miles in 2 hours, I would multiply the sum of the division problems by 2(for 2 hours).

59 x 2 = 118

65 x 2 = 130

None of them equals 116, meaning neither of them drove 116 miles in 2 hours.

Hope I helped you! Have a great day! :)
