Answer: ...
Step-by-step explanation: I will rather let you use a variable and solve (for example: x!
Answer:
1. 9/10
2. 14/15
3. 1 1 /6 or 7/6
Step-by-step explanation:
1. Change the 5, the denominator to 10. 8/10
then add to 1/10 8/10 + 1/10= 9/10
2. Change both denimnators to 15. You will then get 9/15 and 5/15.
Add them together and get 14/15
3. Change both denominators to 6 and you will get 3/6 and 4/6.
Add them together to get 7/6.
If you want to make it into a mixed fraction it would be 1 1/6 (as in one and one-sixth)
Answer:
Step-by-step explanation:
Area of circle = 56 cm²
πr² = 56
3.14r² = 56
r²=56/3.14
r²= 17.83
r = √17.83
r = 4.22 cm
The diameter of the circle = diagonal of the square
Diagonal of the square = 2 * 4.22 = 8.44 cm
x² + x² = 8.44²
2x² = 71.2336
x² = 71.2336/2
x² = 35.6168
x = 5.967 cm
Ok, a=f/m
What we need to do is isolate the variable, m.
a=f/m
*m *m
a*m=f
m*a=f
/a /a
m=f/a
There's your answer.
