what is the reciprocal of 3/ 8 in a b form

The equation we should solve to find b is option A:sin 55°/b = sin 30°/8

What is trigonometry?

Trigonometry is a branch of mathematics that deals with the relationships between the sides and angles of triangles.

We can use the law of sines to solve for the missing side length of the triangle. The law of sines states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is constant for all sides of the triangle. In other words:

a/sin A = b/sin B = c/sin C

where a, b, and c are the side lengths of the triangle, and A, B, and C are the angles opposite those sides.

Using this formula, we can write:

b/sin B = a/sin A

Substituting the given values, we get:

b/sin 30° = 8/sin 55°

Now, we can solve for b by cross-multiplying:

b = 8(sin 30° / sin 55°)

Therefore, the equation we should solve to find b is option A:

sin 55°/b = sin 30°/8

Note that options B and C have the sine and cosine terms reversed, respectively, and option D uses the law of cosines, which is not necessary to solve this problem.

Answer: The slope is 2/3:)

Step-by-step explanation: (2,5) and (8,9)

9-5 =4 /2=2

8-2 =6 /2= 3

Answer: 2/3 or 4/6.

Step-by-step explanation:

Slope = (y2-y1) / (x2-x1)

(9 - 5) / (8-2)

= 4/6, which reduces to 2/3.

The slope of the line between the two given points is 4/6, or 2/3 in simplest terms.

Answer:

20˚F - (-12˚F)

Step-by-step explanation:

Highest temperature of the week = 20˚F

Lowest temperature of the week = -12˚F

The difference between the highest and the lowest temperature actually means to subtract the lowest from the highest temperature.

The required expression is;

20˚F - (-12˚F)

The correct question is

A watch loses 30 secs every hour .If the watch was set right on Sunday 11:30pm .What is time did it show after 10 hours?

(a) Monday 9:25am

(b) Monday 9:30 am

(c) Monday 9:35

(d) Monday 9:25pm

Answer:

(a) Monday 9:25am

The time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

Step-by-step explanation:

We are given that a watch looses 30 seconds in one hour and the Watch was set on 11:30pm on Sunday.

we need to find the time this watch will show after 10 hours from starting at 11:30pm on Sunday.

In 1 hour = 30 seconds is lost

In 10 hours = 30*10 = 300seconds

Converting 300 seconds into minutes we get

 = 300/60 = 5 minutes

This means whatever the actual time will be this watch will shows 5 minutes less.

10 Hours from 11:30pm on Sunday will be

9:30am on Monday morning

but since the watch is slow by 30 seconds each hours which will make 5 minutes difference from the real time in 10 hours so the time shown by the watch will be

9:25am on Monday morning.

Therefore the time shown by the watch in 10 hours from its starting at 11:30pm on Sunday will give 9:25am on Monday.

Answer:She sold 21 magazines on Thursday

Step-by-step explanation:

Step 1

The Total price  of magazine sold on Thursday, Friday and Saturday, she sold $66 .

if she sold $3 more on Thursday than she did on Friday and $6 more on Saturday than she did on Thursday. The expression of the sales can be given as    

Let T represent  Thursday

F represent Friday

S represent Saturday such that

 T + F+ S= 66

T+ T-3 + T+6= 66

Step 2----- Solving

T+ T-3 + T+6= 66

3T - 3+ 6=66

3T+3= 66

3T= 66-3

3T=63

T= 63/3

T= 21

F= T-3= 21-3 =18

S = T+6 = 21+6= 27

She sold 21 magazines on Thursday, 18 on Friday and 27 on Saturday

Answer:

Step-by-step explanation:

The answer is false because 15 + 12 does not equal 220

15 + 12 = ?

It equals 27 if you got your calculations right.

You could also find out if the answer is right if you subtract 220 by one of the numbers ( 15 or 12 ) and if you get the number that you didn't subtract, then that is correct.

Here's an example.

220 - 15 = ?

220 - 15 = 205

205 does not equal 12, so it is wrong or F A L S E.

• Remove minus in the exponent and invert the base:

= (1/22)5

• Expand the multiplication:

= (1/22) * (1/22) * (1/22) * (1/22) * (1/22)

• Find your result:

= 1/5153632 ≈ 0.000000194038

Step-by-step explanation:

Conversion between Miles and Kilometer:

1 mile = 1.609km.

100 miles = 1.609km * 100 = 160.9km,

160.9km - 100km = 60.9km.

Hence the 2 places that are 100 miles apart is 60.9km further away than the places that are 100km apart.
