Answer: There are 9 possible treatments .
Step-by-step explanation:
There are 3 different baking temperatures (350, 400 and 450) and 3 different baking times (45 minutes, 55 minutes and 60 minutes).
By Fundamental counting principle,
Number of treatments = (Number of different baking temperatures) x (Number of different baking times)
= 3 x 3 = 9
Hence, there are 9 possible treatments .
4x + x = 1200
5x = 1200
x = 12 × ( 100 ÷ 5 )
x = 12 × 20
x = 240
______________________________
Larger : 4 × 240 = $ 960
lower : 1 × 240 = $ 240

Answer:
-15
Step-by-step explanation:
We proceed as follows;
In this question, we want to fill in the blank so that we can have the resulting expression expressed as the product of two different linear expressions.
Now, what to do here is that, when we factor the first two expressions, we need the same kind of expression to be present in the second bracket.
Thus, we have;
2a(b-3) + 5b + _
Now, putting -15 will give us the same expression in the first bracket and this gives us the following;
2a(b-3) + 5b-15
2a(b-3) + 5(b-3)
So we can have ; (2a+5)(b-3)
Hence the constant used is -15
Answer:
- It has taken Jake about 40 minutes to finish his Spanish homework.
Step-by-step explanation:
<u>We know that:</u>
- Homework = 4 hours = Spanish + Math + Science + History
- Spanish = 4 hours x 1/6
- Math = 4 hours x 1/4
- Science = 4 hours x 1/4
- History = 4 hours x 1/3
<u>Work:</u>
- Spanish = 4 hours x 1/6
- => 2 hours x 1/3
- => 2/3 hour
- => 2/3 x 60 minutes
- => 40 minutes
Hence, it has taken Jake about 40 minutes to finish his Spanish homework.
