Remark
You need to do some trig to get the final answer. There is no way around it. You can however, solve the first part with the Pythagorean Theorem.
Step One
Find AB
AB^2 = DB^2 + AD^2
AB^2 = 7.5^2 + 4.9^2
AB^2 = 56.25 + 24.01
AB^2 = 80.26
AB = sqrt(80.26)
AB = 8.9588
Step Two
Move to the triangle on your right. Find x
Tan(C)= opposite / adjacent
Tan(55.8) = AB/adjacent
Tan(55.8) = 8.9588/ x Multiply both sides by x
x * tan(55.8) = 8.9588 Divide by tan(55.8)
x = 8.9588/tan(55.8)
x = 6.09
Answer: A
Centimeter is smaller than a meter
"seven" means ' 7 '
"two" means ' 2 '
"the quantity seven plus two" means ' (7 + 2) '
"one hundred times the quantity ..." means ' <em>100 (7 + 2)</em> '
That's the expression.
One of the rules for handling these things is that you should always
take care of anything inside parentheses first. So do that.
(7 + 2) = 9
Now you can can write the expression like this: ' 100 (9) ' .
That's just <em>900 .

Answer: b. Damarias median sale is $52
Step-by-step explanation:
Hi, the correct option is b. Damarias median sale is $52.
If we rank the sales order from lowest to highest
28 46 48 48 52 52 59 60 71 192
Since 52 is the middle value, it's the median, because 4 sales are above it and 4 sales are below it.

Answer:
F^-1(x)= x/5 - 12/5
Step-by-step explanation:
F(x) = 5x +12
y = 5x + 12
5y = x - 12
y= x/5 -12/5
