Answers
Answer:
Correct answer is option C. 354.9 mLThe volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.
Given that, for the volume of soap in a bottle, Ryan determined the margin of error as 354.85 mL to 354.95 mL.
We need to find the volume of soap that he measured.
What is the margin of error?A margin of error tells you how many percentages points your results will differ from the real population value.
Now, the margin of error is 354.85 - 354.95
The volume=354.9 mL (Mid value of 354.85 - 354.95 )
The volume of soap that Ryan measured is 354.9 mL. Therefore, option C is the correct answer.

M is the midpoint of line segment LN. Find the length of LN
Answers
Answer:
Step-by-step explanation:
Here is the complete question;
M is the midpoint of line segment LN. If LM= 3x + 5 and LN= 5x + 40, find the length of LN.
Since M is the midpoint of LN, hence LM + MN = LN and LM = MN
LM + LM = LN
2LM = LN ..... *
Given;
LM= 3x + 5
LN= 5x + 40
Substitute into the eqn *
2(3x+5) = 5x+40
6x+10 = 5x+40
6x-5x = 40-10
x = 30
Get the length LN
LN= 5x + 40
LN = 5(30)+40
LN = 150+40
LN = 190
Hence the length of LN is 190
Answer:
190

In a three-digit number, the tens digit is the same as the hundreds digit. The ones digit of this number is equal to 1/3 of the sum of the other two digits. Find the number if the sum of all its digit is equal to 24.
Answers
Answer:
996
Step-by-step explanation:
the three digit number is;
996
Step-by-step explanation:
The three digit can be written xyz
ones digit is equal to 1/3 the sum of the two other digits
z = 1/3(x + y)
x + y + z = 24
Tens digit is same as hundreds digit
That means x = y
z = 1/3 (x + x) = 2x/3
So;
2x/3 + x + x = 24
Multiply through by 3
2x + 3(2x) = 72
8x = 72
x = 72/8
x = 9
x = y = 9
z = 1/3(18)
z = 6

Each marble bag sold by Mary's Marble Company contains 5 blue marbles for every 4 purple
marbles. If a bag has 35 blue marbles, how many purple marbles does it contain?
Answers
Answer:
The total no. of purple marbles will be:
[tex] \boxed{ \underline{ \rm{28}}}[/tex]
Step-by-step explanation:
It is given that for every 5 blue marbles, we have 4 purple marbles. And similarly we have to find for the no. of purple marbles for 35 blue marbles.
First, Let's divide these 35 blue marbles in groups of 5. We will get:
➝ 35 ÷ 5 = 7 groups
For each group of 5 marbles, there are 4 purple marbles. So for 7 groups, No. of purple marbles will be:
➝ 4 × 7 = 28 purple marbles.

A cookie company sells a box of cookies that weighs 24 ounces. The company states that the acceptable percent error in filling the boxes is 1.5%. What is the difference between the maximum possible weight of a box and minimum possible weight of a box?
Answers
Answer:
The answer is CH8
Step-by-step explanation:
The difference of maximum possible weight and minimum possible weight will be 0.72 ounces
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
Weight of box of cookies = 24 ounces
Acceptable percentage error = 1.5 %
Maximum possible weight =
Weight of box of cookies + Acceptable percentage error
Minimum possible weight =
Weight of box of cookies - Acceptable percentage error
Maximum possible weight = 24 + ( 1.5/100 ) x 24
= 24 + 0.36
= 24.36 ounces
Minimum possible weight = 24 - ( 1.5/100 ) x 24
= 24 - 0.36
= 23.64 ounces
Therefore , difference of Maximum possible weight and Minimum possible weight will be
= 24.36 - 23.64
= 0.72 ounces
Hence , the difference of maximum possible weight and minimum possible weight will be 0.72 ounces

No of students that had enrolled last year = 225
This year, 260 students are enrolled.
We need to find the percent of change in the number of students. It can be calculated as :
P = (change in no of students/initial no of students)×100
[tex]\%=\dfrac{260-225}{225}\times 100\\\\=15.5\%[/tex]
