Answer:
600seconds
Step-by-step explanation:
If Ann can ice a cupcake in 30 seconds, then the total number of cupcakes iced by ann is t/30 cupcakes
Similarly, If Sarah can ice a cupcake in 40 seconds, then the total number of cupcakes iced by Sarah is t/40 cupcakes,
For them to ice 35cupcakes together, then;
t/30 + t/40 = 35
where t is the times taken by both of them to ice 35cupcakes
Find the LCM
40t+30t/1200 = 35
70t/1200 = 35
7t/120 = 35
t/120 = 5
t = 120 * 5
t = 600
This shows that it will take them both 600seconds to ice 35cupcakes
Answer:
17340
Step-by-step explanation:
10,000 * 2.89%
289 * 12
3468 * 5
17340.
<em>(x - 7)(x - 5)</em>
- <em>Step-by-step explanation:</em>
<em>x² - 12x + 35 =</em>
<em>= x² - 5x - 7x + 35</em>
<em>= x(x - 5) - 7(x - 5)</em>
<em>= (x - 7)(x - 5)</em>
A polynomial where the ends are facing downwards is an even-degree polynomial with a negative leading coefficient.
An example for this is : f(x) = -x^2
where the degree is even (2) and the leading coefficient is negative (-1).
When graphing this function, you'll find both ends pointing downwards.
