If you add all the gumballs together you get a total of 20200 gumballs now you just divide 5252 by the total number of 20200 to get the percent of 26% giving us the answer to what the percent of red there is in this container
(add all the number, divide the total number of reds by the total number of gumballs (5252 divided by 20200) which will give you the percent of red gumballs (26%)
To add a mixed number you must first convert it into a heavy headed fraction eg. 12/4
Then you must find a common denominator for all of the fractions like you normally do for regular addition of fractions
After you have added them you must convert the heavy headed fraction back into a mixed number by seeing how many times the numerator goes into the denominator
Answer:
There will be 7 students on each bus.
Step-by-step explanation:
If the class of 63 students is divided into 9 buses with the same number of students traveling in each one, to determine the number of students traveling in each bus it is necessary to perform the following mathematical calculation:
63/9 = X
7 = X
Thus, in each bus 7 students will travel, and in this way all buses will carry the same number of students.
Answer:
z = 1, z = 9
Step-by-step explanation:
Given
z² + 9 = 10z ( subtract 10z from both sides )
z² - 10z + 9 = 0
Consider the factors of the constant term (+ 9) which sum to give the coefficient of the z- term (- 10)
The factors are - 1 and - 9, since
- 1 × - 9 = 9 and - 1 - 9 = - 10, thus
(z - 1)(z - 9) = 0 ← in factored form
Equate each factor to zero and solve for z
z - 1 = 0 ⇒ z = 1
z - 9 = 0 ⇒ z = 9
