Answer:
1 United States Dollar equals
18.94 Mexican Peso
Step-by-step explanation:
All you have to do is line it up with the numbers
The combined area of these three rooms is 189 ft².
Therefore we have the equation
4x + 3x + 2x = 189
9x = 189 |:9
x = 21 ft²
area of the kitchen = 4x = 4(21) = 84 ft²
area of the playroom = 3x = 3(21) = 63 ft²
area of the dinning room = 2x = 2(21) = 42 ft²
A ramp is 17 feet long, rises 8 feet above the floor,
and covers a horizontal distance of 15 feet,
as shown in the figure.
(First box)
A. Sin B = 8/17
B. Cos B = 15/17
C. Sin A = 15/17
(Second box)
A. Sin B = 8/17
B. Cos B = 15/17
C. Cos A = 8/17
Hope this helps!
We are given with two angles of the triangle. The third angle thus in the triangle is 180 - 68 - 24 equal to 88 degrees. we can use the law of sines to determine the lengths of the triangle. Side AC is opposite to angle B while BC is opposite to angle A. Hence
BC/sin 88 = 15/ sin 68
BC = 16.1682 centimeters
