I would say read it well and then write down an equation or expression to represent the data so its easier for you to understand and/or solve.
Answer:
25%
Step-by-step explanation:
100% = 48
1% = 48 ÷ 100 = 0.48
12 ÷ 0.48 = 25%
Answer:
10
Step-by-step explanation:
There is a way to turn this into a simple equation, but I will not go through that.
So the conditions are saying the first term is 40 and for every term after that you multiply the last by .5. So to get the fifth you would multiply the fourth by .5.
We want the third, so we need to multiply the second by .5. To get the second we multiply the first by .5. since the first is 40, 40*.5=20. Then just repeat.
Answer:
Step-by-step explanation:
The vertex form of a parabola:
(h, k) - vertex
We have the vertex at (3, 2) → h = 3 and k = 2.
Substitute:
The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:
<em>subtract 2 from both sides</em>
Finally:
<em>vertex form</em>
<em>use (a - b)² = a² - 2ab + b²</em>
<em>use the distributive property</em>
<em>standard form</em>
Answer:
0.5
Step-by-step explanation:
4-(-3)
4+3=
7
Half of 7 is 3.5
4-3.5=0.5
