Fraser got 14 questions right
questions correct 70/5 = 14
—— ——
total questions 100/5 = 20
therefore he got 14 questions right
you divide 100 by 5 because percents are always out of 100 and that gets you 20 which is how many questions the spelling bee had
then you do the same to the top (divide by 5) and get 14
14/20 questions were answered right
70% of the questions were correct
Answer:
Step-by-step explanation: For example, if we have matrix A whose all elements in the first column are zero. Then, by one of the property of determinants, we can say that its determinant is equal to zero. Hence, A would be called as singular matrix. Note that singular matrices are non-invertible (their inverse does not exist).
We know 20% is 15
and now we find 80%
since 20% x 4 = 80%, we can multiply 15 by 4 to get 80% of 75
15 x 4 = 60
80% of 75 = 60
Answer:
y = 52500(.91)^x
Step-by-step explanation:
Exponential functions are written y = ab^x where a is the starting point and b is the common ratio. We know the initial worth is 52500 and each year the worth decreases 9% of the original year, making it work 91% of the previous value.
