Answer:
a = 8
r = 15%
When t = 3, y= 4.9
Step-by-step explanation:
8 represents the original amount because that's what you're increasing, so a=8.
To find your percentage, look into the parenthesis to see the decimal. We see that it's 0.15, but that's not a percentage yet, so you have to multiply it by 100. Or, moving your decimal two times to the right. Therefore, r=15%.
Now to find what the function will equal when t=3, simply plug 3 for t. I've always used a calculator for this so I'm not going to write it out (sorry). Your result should be 4.9 (this is already rounded to the nearest tenth for you).
Answer:
50
Step-by-step explanation:
Fastest method for calculating 34 is 68 percent of what number. Assume the unknown value is 'Y' 34 = 68% x Y. 34 = 68 / 100 x Y Multiplying both sides by 100 and dividing both sides of the equation by 68 we will arrive at: Y = 3 x 100 / 68. Y = 50%. Answer: 34 is 68 percent of 50
Answer:
Amit will get 5 questions right.
Step-by-step explanation:
Given is that Amit is going to guess on all 20 questions of his multiple-choice test. Each question on the test has 4 answer options. This means that by random guessing he should get 1 out of 4 answers correct.
Hence, the best prediction for the number of questions that Amit will answer correctly is :
= 5
Amit will get 5 questions right.
