Answer:
The value of x is 26 degrees
Step-by-step explanation:
1: 1/4 of a circle (360 degrees) is 90 degrees.
2 90 - 64 = 26
x^2 - 3x + 9 - 5x + 10 = 0
x^2 - 8x + 19 = 0
Answer:
radius = 6miles
Step-by-step explanation:
πr² = area
π6²
π36
Well the centroid is the point that connects the median of a side with the opposite vertex. This means that each line is split i half. Notice that line HG is split in half by point K. that means that each of the segments that K splits is equal. so we know
HK = KG
and we know
HK = 3x
KG = x + 8
since
HK = KG then
3x = x + 8
2x = 8
x = 4
now we have x. we know that the each line that runs from a midpoint to a vertex is seperated by the centroid. the 2 line segments are a 2:1 ratio. so
2*JL = 1LG
we know
JL = x + 3
so
2 * (4 + 3) = LG
LG = 14
To solve this is you have to find the price per ounce for each item by simply dividing the price by the ounces.
For the oat cereal divide $3.90 by 15
3.90/15
.26 per ounce
For the rice cereal divide $3.30 by 11
3.30/11
.30 per ounce
The oat cereal costs less per ounce since it is only .26 per ounce whereas the rice cereal is .30 per ounce.
Hope this helps!
