Answer:
22.5 cm, 30 cm, 37.5 cm
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 + 5 = 12 parts
Divide the perimeter by 12 to find the value of one part of the ratio.
90 cm ÷ 12 = 7.5 cm ← value of 1 part of the ratio, thus
3 parts = 3 × 7.5 cm = 22.5 cm
4 parts = 4 × 7.5 cm = 30 cm
5 parts = 5 × 7.5 cm = 37.5 cm
The 3 sides are 22.5 cm, 30 cm and 37.5 cm
It is the second function:
y=(1/2)^(x-3)
When x=0, the exponent is -3. (1/2)^-3 is 8.
y = 8+1 = 9
If you add a zero at the end it is easier to understand. 0.20 > 0.18 because 20 is greater than 18
So I added all of the numbers of tourists together, I got 30 tourists. Then I saw that the number of tourists that visisted the museum but not the zoo was 5. I divided 5 by 30 and got that there was a 16% chance that a randomly selected tourist would of visited the museum but NOT the zoo.
Hope this helps!
