Step-by-step explanation:
Draw diagonal AC
The triangle ABC has sides 17 and 25
Say AB is 17, BC is 25
Draw altitude on side BC from A , say h
h = 17 sin B
Area = 25*17 sin B = 408
sin B = 24/25
In ∆ ABC
Cos B = +- 7/25
= 625 + 289 — b^2 / 2*25*17
b^2 = 914 — 14*17 = 676
b = 26
h = 17*24/25 = 408/25 = 16.32
Draw the second diagonal BD
In ∆ BCD, draw altitude from D, say DE =h
BD^2 = h^2 + {(25 + sqrt (289 -h^2) }^2
BD^2 = 16.32^2 + (25 + 4.76)^2
= 885.6576 + 266.3424
BD = √ 1152 = 33.94 m
The answer is 16. 7 is 1/4th the value of 28, so 4 should be 1/4th the value of 16.
An expression for “7 divided by c” is 7/c or 7 ÷ c
Answer:
A person should work 32 hours to earn $384
Step-by-step explanation:
A worker's earring E are a function of the number of hour, H at a rate of 12/hr.
We need to write the function.
The function will be:
Earning is represented by E and Hour is represented by H
Now, How many hours would a person have to work to earn 384
We are given E=384, we need to find H
Putting values in above function and finding hours H
So, A person should work 32 hours to earn $384
2x+5y=8
5y=-2x+8
y=-2/5x+8/5. As a result, the y-intercept is 8/5 or 1 3/5. Hope it help!
