Answer:The circumference = π x the diameter of the circle (Pi multiplied by the diameter of the circle). Simply divide the circumference by π and you will have the length of the diameter. The diameter is just the radius times two, so divide the diameter by two and you will have the radius of the circle!Hope it helps!!!!
Step-by-step explanation:
Let X = science homework.
Then math homework would be 3x ( three times as long).
Now you have math plus science = 64 minutes:
x + 3x = 64
Combine like terms:
4x = 64
Divide both sides by 4:
x = 64 / 4
x = 16
He spent 16 minutes on science and 48 minutes on math.
Answer:
true
Step-by-step explanation:
a square will always be a rectangle but a rectangle will not always be a square.
<span>product of a number and 10: 10n
</span><span>Seven less than the product of a number and 10: 10n - 7
so
</span><span>Seven less than the product of a number and 10 is 50:</span>
10n - 7 = 50
----------------------------
if you need to find the number n then
10n - 7 = 50
10n = 57
n = 57/10
n = 5.7
