Answer:
b = 38.22
Step-by-step explanation:
In the given triangle ABC, a = 3, b = 5 and c = 7 is given.
We have to find the measure of angle b.
To get the measure of any angle we will apply cosine rule in the triangle.
b² = a² + c² - 2ac(cosb)
5² = 3² + 7² - 2×3×7×cosb
25 = 9 + 49 - 42×cosb
25 = 58 - 42cosb
-42cosb = 25 - 58 = -33
cosb =
cosb = 0.7856
b = 38.22
b = 38.22 is the correct answer.
Answer:
β = arccos((a^2 + c^2 - b^2)/(2·a·c))
β = arccos((3^2 + 7^2 - 5^2)/(2·3·7)) = 38.21°

Final answer:
Frank can mow at a rate of 6/5 lawns per hour. In 50 hours, by multiplying the rate by the total time, we find that Frank can mow a total of 60 lawns.
Explanation:
To calculate this, we should utilize basic mathematical operations that apply to rate problems. We know Frank's rate is 6/5 lawns per hour, and we are given a total time of 50 hours.
So, to find the total number of lawns Frank can mow in 50 hours, we simply multiply his rate (6/5) by the total time (50 hours). This gives us (6/5) * 50 = 60 lawns.
Therefore, Frank can mow 60 lawns in 50 hours if he maintains his constant rate.

well, we know his rate is 6/5 lawns/hour that means he can do 6 lawns in 1 hour, well, how many can he do in 50 hours?

The 4/6pieces per person or 2/3 of a piece of felt each person will get if four girls and two boys are working on an art project.
What is a fraction?
Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Four girls and two boys are working on an art project.They have four square pieces of felt. If each person gets and equal share of the felt
Let x be the amount of a piece of felt each person will get
From the data given in the equation:
Total number of girls and boys = 4 girls + 2 boys
The total number of girls and boys = 6 people total.
x = 4/6 pieces per person
x = 2/3 of a piece
Thus, the 4/6pieces per person or 2/3 of a piece of felt each person will get if four girls and two boys are working on an art project.

You inspect the series that you have, very carefully.
-- You notice that 9 was increased by 2 to get 11.
-- You notice that 11 was increased by 2 to get 13.
-- You notice that 13 was increased by 2 to get 15.
-- You notice that 15 was increased by 2 to get 17.
By now, it begins to dawn on you. You say to yourself "Self ! I'll just bet
that each term has to be increased by 2 in order to get the next term."
Acting on that assumption, you set out on your flight of prediction:
-- You take the last term, 17, increase it by 2,and get 19.
-- You take the new term that you have created, 19,
increase it by 2, and get 21.
-- You take the 2nd new term that you have created, 21,
increase it by 2, and get 23.
Now you have the three new terms, and that's all you were asked for.
But you're just getting warmed up. Nothing can stop you now.
