<u><em>Answer:</em></u>
70
<u><em>Explanation:</em></u>
Assume that the number we are looking for is x
one tenth is interpreted into 
Now, we know that one tenth of the number is 7, this means that:
* x = 7
Solve for x by multiplying both sides of the equation by 10, we get:
* x * 10 = 7 * 10
x = 70

Answer:
C
Step-by-step explanation:
sin C=12/13
cos A=12/13
so sin C=cos A
Answer:
W = 87 degrees
Step-by-step explanation:
First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:
tanW/tan = 19.0811/tan
W = 19.0811/tan
Now we can use the inverse tan function on the calculator (
) to calculate it:
W = 19.0811 x 
W = 87 degrees

Answer:
A. 48 Km.
B. 62.5 miles.
Step-by-step explanation:
From the diagram given above, the following data were obtained:
50 miles = 80 Km
A. Converting 30 miles to kilometres.
50 miles = 80 Km
Therefore,
30 miles = 30 miles × 80 Km / 50 miles
30 miles = 48 Km
Thus, 30 miles is equivalent to 48 Km.
B. Converting 100 km to miles.
80 Km = 50 miles
Therefore,
100 Km = 100 Km × 50 miles / 80 Km
100 Km = 62.5 miles
Thus, 100 Km is equivalent to 62.5 miles.
Answer:
B
Step-by-step explanation:
3.4 x -3.4= -11.56
3.4 X 3.4 = 11.56 YES
-3.4 X -3.4 = 11.56
-3.4 X 3.4 = -11.56
