What is the correct value of b ?

Mathematics
1 answer:
Vlada [557]3 years ago
4 0

Answer:

b = 4

Step-by-step explanation:

Using the trigonometric identity

cos x = \frac{1}{secx} = \frac{1}{\frac{5}{3} } = \frac{3}{5}

Using the cosine ratio in the right triangle

cos x = \frac{adjacent}{hypotenuse} = \frac{3b}{20}

Hence

\frac{3b}{20} = \frac{3}{5} ( cross- multiply )

15b = 60 ( divide both sides by 15 )

b = 4

Jamie's older brother and his three friends want to split the cost of lunch they also want to leave a 15% tip how much should ea
goldfiish [28.3K]
Answer:
$22.43

Explanation:
We can start by finding the amount that they should tip. The total bill is $78, so we should take 15% of 78 and add it to the total.
0.15 * 78 = 11.7
78 + 11.7 = 89.7
This means that the total cost of the bill, with a tip, is $89.70.
Since there are 4 people, we have to split this total into 4 if they all want to pay equally.
89.70 / 4 = 22.425 = $22.43 !

Hope this helps

Translate the product of 8 and the quotient of 6 and x into an algebraic expression​
WINSTONCH [101]

Answer:

3 x

x + y

Step-by-step explanation:

(think about it with a horizontal line between the two numbers)

When using fractions and whole numbers turn the whole numbers into fractions like ---> 3/1

and if their like 3 5/6 (for example) you would multiply the denominator by the whole number ---> 3*6=18 then add what's on the numerator with it. so 18+5=23 which would make it 23/6

Just some tips for making it easier!

Hope it helps! :)

The third term of an arithmetic sequence is -8, and the fourth term is -20. What is the second term?
Ostrovityanka [42]

In mathematics, an arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. so -20 + 14 is -8 so you just have to add 14 again to -8 to get 6

may I get brainliest please?

hope this helps :)
