It is 58 
That's the 20th number in the sequence since each term is 3 more than the last number. An easy way to do this is multiply 19 times 3 because there are 19 terms after one. Then multiply by 3 because each term is 3 more than the last term. After you do 19 x 3 you get 57 right? Then add 57 to 1, the first term, to get 58.

Each term goes up by 3 so if n is the nth term and y is the value y=3n but the first term is 1 not 3 so
y=3n-2
The 20th term is n=20 so
y= 58

NEED HELP ASAPInstructions: Find the length of the missing sides. Round your answers to the
Pie

Answer:

x = 9.4

y = 17.7

Step-by-step explanation:

Given: The figure

Required: Find x and y

The relationship between length x, length 15 and angle 32 is as follows:

tan \theta = \frac{opp}{adj}

So, we have:

tan\ 32= \frac{x}{15}

Cross multiply:

x =15*tan\ 32

x = 15 * 0.6248693519

x = 9.3730402785

x = 9.4 --- approximated

Similarly:

The relationship between length y, length 15 and angle 32 is as follows:

cos \theta = \frac{adj}{hyp}

So, we have:

cos\ 32= \frac{15}{y}

Cross Multiply:

y * cos\ 32= 15

Solve for y

y = \frac{15}{cos\ 32}

y = \frac{15}{0.84804809615}

y = 17.6876760506

y = 17.7 --- approximated

20 POINTS AND BRAINLIEST!!! Three dentists wanted to compare the ages of their patients. They each calculated their patients’ me
LenKa [72]
Hello,

Looking at the data, you should go with the second and fourth results.

On the second one, Dr. Appiah's M.A.D. is only 9.7 which is less than Dr. Singh's M.A.D. of 14.1

On the fourth one, Dr. Cantwell and Dr. Singh both have a M.A.D. that is only 0.1 from 14, so their ages vary by about the same amount.

Best of luck,
