Answer:
56
Step-by-step explanation:
1:8= 7:?
1*?=7
/1 /1
1*7=7
8*7=56
1:8 = 7:56
Answer:
5.3 hours
Step-by-step explanation:
Given:
3 hours = 8lbs. turkey
?? hours = 14lbs. turkey
Do proportions:
= 
<-- Cross Multiply
42 = 8x <-- Solve for x
x = 5.25
Round to the nearest tenth:
x = 5.3 hours
Carry out the mult.: f(x) = -[x^2 - 21x + 9x - 189]
Combine like terms: f(x) = -[x^2 - 12x - 189]
Eliminate the brackets [ ]: f(x) = -x^2 + 12x + 189
Identify coefficients a, b and c: a= -1, b=12, c=189
The equation of the axis of symmetry is x = -b/(2a), which here equals
x = -(12)/[2(-1)], or x = 6
This is also the x-coordinate of the vertex. Plug x=6 into the original equation to calculate the y-coordinate.
Jose is false because the sun which makes it a day only shines none side of the earth while the moon is on the other side so on the other half of the hemisphere the days would be getting shorter while the days get longer on the other half of the hemisphere.
