Answer:

EF=15.4\ ft

Step-by-step explanation:

we know that

In the right triangle DEF

tan(E)=\frac{FD}{EF} ----> by TOA (opposite side divided by adjacent side)

substitute the given values

tan(32^o)=\frac{9.6}{EF}

solve for EF

EF=\frac{9.6}{tan(32^o)}=15.4\ ft

What is 26-2b>2(3b+4)
Brrunno [24]
26 - 2b > 2(3b + 4)    |use distributive property: a(b + c) = ab + ac

26 - 2b > 6b + 8    |subtract 26 from both sides

-2b > 6b - 18    |subtract 6b from both sides

-8b > -18    |change signs

8b < 18    |divide borh sides by 8

b < 18/8

b < 9/4

b < 2.25

The temperature was very cold then it dropped 10 degrees and then it increased 40 degrees the temperature is now 16 degrees. Wha
jasenka [17]

Answer:

The initial temperature was To = -14 degrees

Step-by-step explanation:

Solution:-

- We will take the starting temperature to be = Ti

- The final temperature, Tc = 16 degrees

- We are given that there is a drop of 10 degrees from initial temperature To. We can mathematically express this as:

                                 To - 10

- Then there is a rise of 40 degrees after the drop of 10 degrees. The mathematical expression would be:

                                 To - 10 + 40

- The current temperature is Tc. We can equate the expression developed to final temperature:

                                 To - 10 + 40 = Tc

- Solve for To:

                                 To = 16 - 40 + 10

                                 To = -14 degrees
