This is right
The system requires me to have 20 characters in my answer so I am just gonna add this.
Answer:
$342.7
Step-by-step explanation:
Let the sale price be x.
So,
x - 30% of x = $239.89
x - 30/100*x = 239.89
(100x-30x)/100 = 239.89
70x = 239.89 *100
x = 23989/70
x = $342.7
sale price = $342.7
Answer:
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The area of a trapezoid is equal to
![A=\frac{1}{2}[b_1+b_2]h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Bb_1%2Bb_2%5Dh)
where
b_1 and b_2 are the length of the parallel bases
h is the height (perpendicular distance between the parallel bases)
we have
substitute
![A=\frac{1}{2}[210+480]320=110,400\ mi^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B210%2B480%5D320%3D110%2C400%5C%20mi%5E2)
Answer:
21/20, or 1.05.
Step-by-step explanation:
In this case, the measure of angle R is the same as angle V.
To find the tangent of a triangle, you do opposite over adjacent.
So, the tangent of angle V is 21 / 20.
That means that tan(R) = 1.05.
Hope this helps!
