Answer: 48
Step-by-step explanation:
l = w + 7
2w + 2l = 178
2w + 2(w + 7) = 178
2w + 2w + 14 = 178
4w = 164
w = 41
l = w + 7
l = 41 + 7
l = 48
Answer:
The answer would be 702.5
Step-by-step explanation:
If;
A = Adjacent
O = Opposite
H = Hypotenuse
Then,
Sin Ф = O/H
Cos Ф = A/H
Therefore,
(Sin Ф)/Cos Ф) = (O/H)/(A/H) = (O/H)*(H/A) = O/A
Now,
tan Ф = O/A ----
Therefore, it is true that
tan Ф = SinФ/CosФ
Answer:
Red Cell is 300 times larger than the virus
Step-by-step explanation:
Size in scientific Notation
- Red Cell = 9 * 10^-6
- Virus = 9 * 10^-8
Procedure.
- Count the number of zeros in the decimal
- Red Cell = 5 ; virus = 7
- And one more to each
- Red Cell = 6; virus = 7
- change the numbers to minus
- Red Cell = -6 ; virus = - 7
- The last row is the powers as shown above.
Answer
9*10^-6/3 * 10^-8
3*10^(-6 - - 8)
3*10^(- 6 + 8)
3^10^2 or 300 times larger
Answer:
6 2/9
Step-by-step explanation:
4 7/9 + 1 4/9
Since the denominators are the same, we can add
5 11/9
We need to fix the improper fraction
5 + 9/9 + 2/9
5+1+2/9
6 2/9
