The ramp is modelled as shown in the diagram below.
The angle of elevation from the car is the angle form by the horizontal line and the observer eye from the car. In the diagram, this angle is marked by

We use trigonometry ratio to work out the value of





°
Answer:
84
Step-by-step explanation:
let a be the 1's digit and b the 10's digit, then
a = 2b ← twice the 10's digit, thus
sum = 2b + b = 12, that is
3b = 12 ( divide both sides by 3 )
b = 4
and a = 2b = 2 × 4 = 8
The 2 digit number is 84
Answer:
8
Step-by-step explanation:
hypotenuse^2= leg^2 + leg^2
10^2= 6^2 + x^2
100= 36 + x^2
100-36= x^2
64= x^2
√64=√x^2
8= x
Answer:
$325,120.00
Step-by-step explanation:
This is my first answer so hopefully I do this correctly. In essence it's exactly the same as number 22!
The realtor earns $10,566.40 off of a comission of 3.25%. A comission is pretty much just a cut of however much the house cost; which a realtor gets for helping to sell the property. So we could say that the comission is equal to 3.25% of however much the house cost.
Say the house price = $x, so our equation would be:
$10,566.40 = (3.25%)•($x) or
10,566.40 = (.0325)•($x)
By solving for x we get:
$x = (10,566.40)÷(.0325) = $325,120
