The ratio of Kailyn's money to Nathan's money is 4:9. If Nathan has $45, how much do
they have all together? (I need help asap)

Answers

Answer 1

Answer:

$65

Step-by-step explanation:

Step one:

we are told that the ratio of Kailyn's money to Nathan's money is

4:9,

Nathan has $45, let Kailyn's money be x

therefore

4/9=x/45

cross multiply we have

9x=45*4

9x=180

divide both sides by 9

x=180/9

x=20

Kailyn's money is $20

Together they have =20+45= $65

There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest inch, how many inches are in 16 meters?

Answers

Answer:

629 inches are in 16 meters

Answer:

Multiply total meters by 100 to get total centimeters:

6 meters x 100 = 600 centimeters.

Now divide total centimeters by 2.554 to get total inches:

600 centimeters / 2.54 = 236.22 inches.

Rounded to the nearest inch = 236 inches.

What is the measure of angle b?

Just show me some work. I don’t need anything else I know the answer

Answers

Answer:

well i mean i guess you know what it is

Step-by-step explanation:

We know that all of the angles in a triangle must add up to 180. so to find the measure of angle b, we can add the two known angles together, and take that number away from 180. (we would do this to find out how much is left to complete a full 180 degrees) 115+31=146. 180-146=34. since all of the angles 31, 115, and 34 add up to 180, we know that 34 is the correct answer

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

[tex](9s + 8)° + 37° = 180°[/tex]

Because they make straight line.

[tex]9s + 8 + 37 = 180[/tex]

[tex]9s + 45 = 180[/tex]

Subtract sides 45

[tex]9s + 45 - 45 = 180 - 45[/tex]

[tex]9s = 135[/tex]

Divide sides by 9

CHECK :

A spinner has 8 equal sectors with different letters for each sector, as shown below:

A spinner with 8 equal sectors is shown. The sectors are labeled B, Y, G, P, O, V, M, and R.

Hamlet spins the spinner 13 times, and it stops at the letter R 9 times. If he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter R?

Answers

Answer:

The theoretical probability of obtaining letter 'r' at the 14th spin is:

1/8

Step-by-step explanation:

It is given that:

A spinner has 8 equal sectors with different letters for each sector.

The sectors are labeled b, y, g, p, o, v, m, and r.

Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.

We are asked to find the theoretical probability that we will get  letter r at the 14th spin.

The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.

Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:

( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)
