The shorter piece is 37 cm
The longer piece is 48 cm:
Step-by-step explanation:
Divide 85 cm by 2 = 42.5
Divide 11 cm by 2 = 5.5
Add them together = 48 cm
85 cm - 48 cm = 37 cm
5.7 square feet = 0.53 square meters
0.53 / 0.75 = 0.71
the smallest would be a)0.71
4.
The equation we have is:
To solve for "a", we want to isolate it in one side.
For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:
Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":
And that is the answer to 4.
Answer:
In this case, y=30 and x=6, so 30=k*5<=> k=30/6=5.
Step-by-step explanation:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
