Answer:
11.2
Step-by-step explanation:
or 11 1/5
First, you would have to combine 3 1/2 and 4 3/4 pounds. That would be 8 and 1/4 lbs. If she used all but 1 3/8 lbs, you would have to do 8 1/4 minus 1 3/8. That means she used 7 1/8 lbs of fruit.
The equation would be 3/ 12 + 4 3/4 = 8 1/4 - 1/38 = 7 1/8.
Answer:
about 8 cm
Step-by-step explanation:
The formula for the area of a regular polygon is ...
A = 1/2Pa . . . . where P is the perimeter and "a" is the apothem, the distance from the center to a side
Filling in your numbers, we have ...
20 cm^2 = (1/2)P(5 cm)
Dividing by the coefficient of P, we find ...
2×(20 cm^2)/(5 cm) = P = 8 cm
The perimeter of the pentagon is about 8 cm.

<em>Comment on the problem</em>
This calculation makes use of the area formula, as apparently intended. A regular pentagon with an apothem of about 5 cm will have an area of about 90.8 cm^2. The given geometry is impossible, as the pentagon is nearly 10 cm across. It cannot have a perimeter of only 8 cm.
Answer:
the first option
Step-by-step explanation:
equilateral triangles are also equiangular which means each of the three angles is 60°
but you can have an acute triangle with angle measures that are all acute (for example, 59°, 85°, and 36°) that is not equilateral
