OC. 5 2/9

O E. 5 5/9
Answers
Answer:
5 4/9
Step-by-step explanation:
Convert a mixed number 2 19
to a improper fraction: 2 1/9 = 2 19 = 2 · 9 + 19 = 18 + 19 = 199
To find new numerator:
a) Multiply the whole number 2 by the denominator 9. Whole number 2 equally 2 * 99 = 189
b) Add the answer from previous step 18 to the numerator 1. New numerator is 18 + 1 = 19
c) Write a previous answer (new numerator 19) over the denominator 9.
Two and one ninth is nineteen ninths
Add: 19
9+ (-29) = 19 + (-2)9= 179
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 9) = 9. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 9 = 81. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - nineteen ninths plus minus two ninths = seventeen ninths.
Conversion a mixed number 3 59
to a improper fraction: 3 5/9 = 3 59= 3 · 9 + 59= 27 + 51 = 329
To find new numerator:
a) Multiply the whole number 3 by the denominator 9. Whole number 3 equally 3 * 99 = 279
b) Add the answer from previous step 27 to the numerator 5. New numerator is 27 + 5 = 32
c) Write a previous answer (new numerator 32) over the denominator 9.
Three and five ninths is thirty-two ninths
Add: the result of step No. 2 + 32
9= 179+ 329 = 17 + 329 = 499
For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of the both denominators - LCM(9, 9) = 9. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 9 × 9 = 81. In the next intermediate step the fraction result cannot be further simplified by canceling.
In words - seventeen ninths plus thirty-two ninths = forty-nine ninths.

Ten voltage measurements in a circuit have produced the following values: 49.3, 50.1, 48.9, 49.2, 49.7, 50.5, 49.9, 49.3, 49.8, 50.2 If the standard deviation for the above data set is 0.50 V, Which of the values can be rejected:
Answers
Answer:
48.9 and 50.5 are rejected.
Step-by-step explanation:
Since the standard deviation shows the spread of the values of the voltages, we need to find the mean of the values and use the standard deviation to find the minimum and maximum voltage allowed.
So mean μ = Σx/N where x = individual values of voltage and N = number of values = 10
So, μ = Σx/N
= (49.3 + 50.1 + 48.9 + 49.2 + 49.7 + 50.5 + 49.9 + 49.3 + 49.8 + 50.2)/10
= 496.9/10
= 49.69
≅ 49.7 V
So, the acceptable values of voltage are in the range μ ± σ where σ = standard deviation = 0.50 V.
So, the acceptable values of voltage are in the range 49.7 ± 0.50 V
So, minimum value = 49.7 V - 0.50 V = 49.2 V
and maximum value = 49.7 V + 0.50 V = 50.2 V
So any voltage outside the range 49.2 V ≤ x ≤ 50.2 V is rejected.
There are two values outside this range which are 48.9 and 50.5. So these two values are rejected.

Evaluate: f(x) = 2x^2 + 6x - 4; f(-5) *
Answers
[tex]f(x)=2x^2+6x-4\\[/tex]
Find f(-5) by substituting x = -5 in the equation.
[tex]f(-5)=2(-5)^2+6(-5)-4\\f(-5)=2(25)-30-4\\f(-5)=50-34\\f(-5)=16[/tex]
Therefore, the answer is f(-5) = 16
Answer:
f(-5)=126
Step-by-step explanation:
what you would do first is plug -5 in for x which would give you the equation of f(-5)= 2(-5)^2 + 6(-5) -4
then you multiply the negative 5 and you will get
f(-5)= -10^2 + 30 -4
remove that square by multiplying -10 by -10 and you will get
f(-5)= 100 + 30 -4
combine like terms and you will get
f(-5)=126

segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
Answers
Answer:
YZ is located at Y (0, 1) and Z (-2, 1) and is one-third the size of Y'Z'.
Step-by-step explanation:
Since Y'Z' was dilated from the origin at a scale factor of 3, you can divide its X and Y coordinates by 3 to find the coordinates of YZ.
The statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.
What is dilation?The transformation dilation is used to resize an item. Dilation is a technique for making items appear larger or smaller. The image created by this transformation is identical to the original shape.
The question is incomplete.
The complete question is:
Segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3). segment YZ was dilated at a scale factor of 3 from the origin. Which statement describes the pre-image?
segment YZ is located at Y (0, 9) and Z (−18, 9) and is three times the size of segment Y prime Z prime.segment YZ is located at Y (0, 3) and Z (−6, 3) and is the same size as segment Y prime Z prime.segment YZ is located at Y (0, 1.5) and Z (−3, 1.5) and is one-half the size of segment Y prime Z prime.segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime.As we know, in the dilation image of the two-dimensional figure can be larger or smaller depending on the dilation factor.
We have:
segment Y prime Z prime has endpoints located at Y'(0, 3) and Z'(−6, 3).
After dilation:
Y (0, 1) and Z (−2, 1)
Thus, the statement fourth "segment YZ is located at Y (0, 1) and Z (−2, 1) and is one-third the size of segment Y prime Z prime" is correct.

Beth wants to paint her rectangular night stand that is 42 inches long and 28 inches wide. A quart of paint covers about 350 square inches. How many quarts of paint will Beth need to cover the entire night stand?
Answers
Answer:
3.36 quarts of paint
Step-by-step explanation:
In this question, we're trying to find how much paint she will need to cover the night stand.
First, we need to find the area.
Solve for the area (rectangle = l * w):
42 · 28 = 1176
Now, we know that 1 quart of paint covers 350 square inches.
To find how much paint she needs, divide 1176 by 350:
1176/350 = 3.36
This means that she needs 3.36 quarts of paint to cover her whole nightstand.
