Answer:
45
Step-by-step explanation:
6 semicircles = 3 circles
The formula of the area of a equilateral triangle:
We have a = |AE| = 3cm. Substitute:
The formula of the area of a circle:
We have 2r = |AE| =3cm → r = 1.5cm. Substitute:
The area of the figure:
Answer:
Step-by-step explanation: Part 1) The units rates are
A)
B)
C)
D)
Part 2) The best buy is the size 48 1/4 we know that To find out the unit rate divide the total cost by the total volume
Part 1) Calculate the unit rate for each size
case A) we have 8 1/2 ounce bottle costs $0.99 Convert mixed number to an improper fraction
Find the unit rate
case B) we have
18 2/2 oz. bottle costs $1.49
Convert mixed number
Find the unit rate
case C) we have
48 1/4 oz. carton costs $2.49
Convert mixed number to an improper fraction
Find the unit rate
case D) we have
64 3/4 oz. carton costs $3.75
Convert mixed number to an improper fraction
Find the unit rate
Part 2) which size is the best buy
we know that
The best buy is the one with the smallest unit rate
so
The best buy is the size 48 1/4 oz
Answer:
2
Step-by-step explanation:
a) Calculate the probability that she
b) Work out the probability that she
gets an even number and a tail.
a)
Probability is
No. For fractions to be equal, both the numerators and denominators have to be proportional.
Since both denominators are 2, the denominators would have to be just 3 or just 4.
