Answer:
12/25
Step-by-step explanation:
Change the decimal to fraction form. Move the decimal point to the right two place values and set over 100:
0.48 = 48/100
Note that you must simplify. Divide common factors from both the numerator and denominator:
(48/100)/(4/4) = 12/25
12/25 is your simplest form fraction.

Answer:
D
Explanation:
When u try to find the lengths of a right triangle you use the formula c = √(a² + b²). When you use the formula you take your TWO smallest numbers which is 12.5 and 30 you would plug it in the formula and solve and when you solve you should get 32.5. I checked my answer on a calculator to make sure it was right so js look at the picture below : )
Answer:
Step-by-step explanation:
Solution:-
- We are given a parametric form for the vector equation of line defined by ( t ).
- The line vector equation is:
L: < 3 + 2t , t + 1 , 2 -t >
- The same 3-dimensional space is occupied by a unit sphere defined by the following equation:
- We are to determine the points of intersection of the line ( L ) and the unit sphere ( S ).
- We will substitute the parametric equation of line ( L ) into the equation defining the unit sphere ( S ) and solve for the values of the parameter ( t ):
- Solve the quadratic equation for the parameter ( t ):
- Plug in each of the parameter value in the given vector equation of line and determine a pair of intersecting coordinates:
40/50?
1.convert the 50 to 100 'cause there are 100 percents in a percent(i just heard that from somebody)
2.50 * 2 = 100 so multiply 40 by 2
3.80,80% is your answer
