Answer: 36 cakes
Step-by-step explanation:
There are 4 bakers in this kitchen and they can each bake a cake in 20 minutes.
This means that the number of cakes baked in 20 minutes is 4 cakes.
3 hours in minutes is:
= 3 * 60
= 180 minutes
The number of 20 minute periods in 3 hours is therefore:
= 180/20.
= 9
If 4 cakes are baked in 20 minutes, the number of cakes in 180 is:
= 4 * 9
= 36 cakes
Answer:
18
Step-by-step explanation:
Rounding it off to nearest 10th place . Since the decimal value is 5 it will round off to +1 , That becomes , 17 + 1 = 18

The perfect square trinomial is x² - 2x + 1.
Hence, the value needed to complete the square of the expression ( x² - 2x + --- ) is 1.
<h3>What value is needed to complete the square?</h3>
The quadratic expression in its standard form is;
ax² + bx + c
Given the expression in the question;
x² - 2x + ------
Compared with the standard for a quadratic expression
Let the missing value be represented by "c"
x² - 2x + c
Now, to find the value of c, we divide the coefficient of x by 2 and then square the result.
Note that, coefficient of x is b
c = ( b/2 )²
We substitute
c = ( -2/2 )²
c = ( -1 )²
c = 1
The perfect square trinomial is x² - 2x + 1.
Hence, the value needed to complete the square of the expression ( x² - 2x + --- ) is 1.
