ANSWER
80%
EXPLANATION
Donovan got 20 questions correct and 5 questions incorrect.
This means that the total number of questions he attempted in the test is the sum of correct and incorrect questions:
Total = 20 + 5
Total = 25
To find the percentage of correct answers, we have to divide the number of correct answers by the total number of questions attempted and multiply by 100 (per cent).
That is:
That is the percentage of correct answers.
Given:
The diameter of cloud-water droplet is
The diameter of pinhead is 0.001.
Explanation:
Divide the dimater of cloud-water droplet by dimater of pinhead to determine the times as great is the diameter of a pinhead as the diameter of a cloud-water droplet .
So diameter of a pin-head is 100 times the diameter of water-droplet.
Answer:
3. 18 meters.
4. A= 6. 25cm^2 and P= 10 cm
5. 16 feet and 3 feet.
Step-by-step explanation:
3. base= 2 (A/h)
2 (72/8) = 18
4. A= side^2
2.5^2 = 6.25
P= 4 sides
2.5 x 4= 10
5. 16x3= 48
5r-4 and r=-5 so it would be 5(-5)=-20, then -4 , so is is -24
Answer:
Yes
Step-by-step explanation:
