Answer:
Step-by-step explanation:
Let q represent the number of quarters. Then Tony's coin value is ...
0.25q +0.10(25 -q) = 4.00
0.15q +2.50 = 4.00 . . . . . . . . eliminate parentheses, collect terms
0.15q = 1.50 . . . . . . . . . . . . . . subtract 2.50
q = 10 . . . . . . . . . . . . . . . . . . . . divide by the coefficient of q
Then the number of dimes is ...
25 -10 = 15
Tony has 15 dimes and 10 quarters.
For this case what we should do is write correctly the given equation:
D ^ 2 = W ^ 2 + H ^ 2
We substitute the values:
D = 17inch
H = 9inch
Substituting:
17 ^ 2 = W ^ 2 + 9 ^ 2
We clear the value of W:
W = root (17 ^ 2 - 9 ^ 2)
W = 14.4 inch
Answer:
The width of the laptop screen is:
D. W = 14.4 inch
the answer is in your question lol.
its pi, which is
≈ 3.14 feet ^3
^^^ thats
ur answer
Answer:
-20.1 degrees Celsius
Step-by-step explanation:
The system started at -12.6 Celsius. It then cooled 7.5 degrees during a reaction. Because it cooled, that means the difference is negative.
-12.6 degrees Celsius - 7.5 degrees Celsius = -20.1 degrees Celsius
It is important to always remember your correct names and variables for numbers in chemistry!
Answer:
4 students
Step-by-step explanation:
Although I am not sure if I am completely correct. I’ll try my best.
<u>We know:</u>
The numbers 0-12 on the frequency table is the number of windows.
The numbers on the bottom is the amount of students.
-
<u>What we can see:</u>
As we can see..
- the 0-4 section in the table shows that only 0-4 students have 9 windows.
- The 5-9 sections shows that only 5-9 students have 10 windows.
- The 10-14 sections shows that 10-14 students have 0 windows.
- The 15-19 sections shows that 15-19 students have 4 windows.
- The 20-24 sections shows that 20-24 students have 2 windows.
-
<u>Calculations:</u>
Since the number of students that have the amount of windows less than 10 is 4 (0-4 section) and 0 (10-14 section)
Add.
4+0
= 4
Therefore, 4 students have less than 10 windows.
