The probability that the next 4 winners will all be 7th grade students is 3/4
15.6 oz i believe. 3/4 is equal to 75% .75x20.8oz = 15.6
12.56
To find the circumference of a circle, the formula is diameter • π. The diameter is twice the radius, so first you must multiply 2 • 2 = 4. So the diameter is 4.
The question states to use 3.14 instead of π, so from here we multiply 4, the diameter, by 3.14 to find the circumference.
4 • 3.14 = 12.56, so the circumference is 12.56
Answer:
x=7,x=-2
Step-by-step explanation:
x^2-5x-14=0
x^2-7x+2x-14=0
x(x-7)+2(x-7)=0
(x-7)(x+2)=0
x=7;x=-2
Answer:
m=0.833333
Step-by-step explanation:
(1/16)−3m+1=64
log((1/16)−3m+1)=log(64)
(Take log of both sides)
(−3m+1)*(log(1/16))=log(64)
−3m+1=log(64)
log(1/16)
−3m+1=−1.5
−3m+1−1=−1.5−1
(Subtract 1 from both sides)
−3m=−2.5
−3m
−3
=
−2.5
−3
(Divide both sides by -3)
