First off when multiplying fractions you always multiply straight across. so the answer would be -5/12.
Answer:
Diameter = 19.33
Step-by-step explanation:
Imaging a radius line from O to the endpoints of the 7. call this line R.
Label the part of the vertical line from O to the 90 degree intersection y.
Now you have a right triangle.
Using the Pythagorean theorem:
R² = 7² + y²
also
y = R - 3
substitute for y:
R² = 49 + (R-3)²
R² = 49 + R² - 6R + 9
simplify:
0 = 58 - 6R
6R = 58
R = 9.6667
Diameter = 2(9.6667) = 19.33
(5x+7) + (8x-21) = 90
13x-14 = 90
13x= 104
X=8
The angle measurements are 47, and 43
-2x+3. X intercept is +3. Moves two steps down and one step to the right to land on the point (1,1)
Answer:
25 kilometers per hour
Step-by-step explanation:
I just simply made it into a proportion of 50/2=x/1 and 50 divided by 2 is 25. hopefully that help you.
