<u>Answer:</u>
<h2>
ST = 44.54 ft</h2>
<u>Explanation:</u>
given:
∠T=90° , ∠R=39° and TR = 55 ft
ST = 55×tan(39)
ST = 55×0.80..
ST = 44.54 ft
The answer is B
The formula is 1/6(pie)diameter^3
Answer:
None of the given system of linear inequalities
Step-by-step explanation:
Given
Required
The line inequalities with the above solution
The first set of linear inequalities, we have:
implies that the values of y is -4,-5.....
While implies that y = -2
Hence, the first set is wrong
The second set of linear inequalities, we have:
implies that the values of y is -1,0.....
While implies that y = -2
Hence, the second set is wrong
Answer:
x + 14 = 2(x + 6)
x = 2
Step-by-step explanation:
Let
Algebra book age = x
Chemistry book age = x + 8
In 6 years time
Chemistry book age = x + 8 + 6
= x + 14
Algebra book age = x + 6
the chemistry book will be twice as old as the Algebra book.
x + 14 = 2(x+6)
x + 14 = 2x + 12
x - 2x = 12 - 14
- x = - 2
Divide both sides by -1
x = 2
Check:
Chemistry book age = x + 14
= 2 + 14
= 16
Algebra book age = x + 6
= 2 + 6
= 8
