Answer:
18.0 cm to 1 decimal point.
Step-by-step explanation:
First work out the unknown side (s) of the right triangle using the Pythagoras theorem:
s^2 = 13^2 - 5^2
= 169 - 25 = 144
s = sqrt 144 = 12 cm.
Now consider the other triangle:
s = 12
The missing angle = 180 - 65 - 40 = 75 degrees.
By the Sine Rule:
x / sin 75 = 12 / sin40
x = 12 sin 75 / sin 40
= 18.03

Answer: 50
Step-by-step explanation:
First we have to find the area. To do that, we first have to find the side lengths of the square. Since a square has all four sides same length, we can find this by dividing: 52/4 = 13
Now we'll find the area in square meters: 13 * 13 = 169
So the area is 169 square meters.
So to find out how much that will cost, we will multiply the number of square meters by the amount it cost per square meter: 169 * $5 = $845
So it will cost $845

Answer:
C. 3 1/2 miles per hour
Step-by-step explanation:
I just converted the fractions to decimal form.
5/8 = 0.625 9 + 0.625 = 9.625
3/4 = 0.75 2 + 0.75 = 2.75
Now divide the 2 numbers:
9.625 / 2.75 = 3.5
Finally, convert the decimal back to a fraction:
3.5 = 3 1/2
Hope this helps!
