For a triangle:
A=\frac{bh}{2}
A=\frac{b \times 7.9}{2}
b=AD+DC
Use Pythagorean theorem twice:
AD^{2}+9.4^{2}=7.9^{2}
AD=5.09

DC^{2}+23.2^{2}=7.9^{2}
DC=21.81

Thus:
b=26.9

And:
Area=\frac{26.9 \times 7.9}{2}=106.26

Solve for x and round yout answer to the nearest tenth.
Evgesh-ka [11]

Answer:

x=21.35764429=21.4

Step-by-step explanation:

Take SOHCAHTOA

in this problem you're going to use SOH, which is sine= opposite/hypotenuse

sin31=11/x

Multiply by x as a way to isolate it

x(sin31)=11

divide my sin31 to isolate x

x=11/sin31

x=21.35764429

7*3=( *3)/(4*3)<br> Need to find the missing number before the *3
Butoxors [25]

Answer:

  the missing number is 84

Step-by-step explanation:

Let the missing number be represented by N. Then we have ...

  7*3 = N*3/(4*3)

Canceling common factors on the right, we have ...

  7*3 = N/4

Multiplying by 4 gives ...

  4*7*3 = N = 84

The missing number is 84.

The 700th term in a geometric sequence is 20. If the common ratio of the sequence is 0.25, what is the 699th term?
GenaCL600 [577]
There are two ways to solve this problem. First, you can use the derived formula for geometric sequence which can be used to find any nth term of the sequence. Or, we can use the second easier way. Since we are given with the 700th term, and the asked is the 699th term, then that means,

(699th term)*(Common Ratio) = 700th term
699th term = 700th term/Common Ratio = 20/0.25 = <em>80</em>
