Answer:
Step-by-step explanation:
Given:
Number of eclairs = 3
Number of humbugs = 
Number of mints = 
Therefore, total number of sweets in the jar is,
Now, probability of selecting a sweet to be humbug is given as:
Therefore, the probability that it is a humbug is .
Answer:
3/4
Step-by-step explanation:
3 goldfish
4 total pets
18. The perimeter is simply √3 + √3 + √3 + √3 or 4√3cm, since the perimeter is just all sides added together. You could add the decimal numbers together using a calculator, which I'm not sure if you're supposed to do in your class.
The area is just width times length, so √3 • √3 = 3cm².
19. The perimeter is 2√5 + 2(9 - √5).
This can also be written as 2√5 + 18 - 2√5, which leaves you with a perimeter of 18ft.
The area would be √5 • (9 - √5), which leaves you with (9√5 - 5)ft².
20. The formula for the perimeter (or circumference) of a circle is π times the diameter of the circle. Using the radius of the circle, 1/π, the diameter is 2/π, so
π • 2/π = 2. The circumference of the circle is 2 inches.
The area of the circle is calculated with the equation πr², so
π(1/π)² = π • 1/(π²) = π/(π²) = π. The area is simply π in².
Those are the ones that are in 50s or

9 of the hundreds
10 per each
9 times 10=90
so there are 90 of them
