We use this formula:
<span>Area = ½ • side 1 • sine (A) • side 2
</span>Area = <span>½ • 6 • sine (74) • 7
</span><span>Area = <span>21 • sine (74)
Area = 21*0.96126
Area = </span></span><span><span><span>20.18646
</span>
</span>
</span>
Area = 20.2 (rounded)

25/100 =0.25
10 x 0.25= 2.5
To find the number of days, divide the total swam by the average:
Days = 48 / 3.2 = 15
They swam for 15 days.
Ok so...
You want to move the decimal point to the right until the number is greater than 1 but less than 10.
The number will end up being 5.2
You moved the decimal point 3 times to the right.
So it will be 5.2 x 10^-3. It is negative because you moved it to the right. The exponent would be positive if you moved it to the left
Answer: m=6, m=-4
Step-by-step explanation:
To solve this proportion, we have to cross multiply.


Now that we have cross multiplied, we actually need to FOIL the left side to expand the equation.

Combine like terms.

We can move all terms to one side and then solve for m.

We can actually factor this to:

We set each factor equal to 0 to find m.
m-6=0
m=6
m+4=0
m=-4
