Eduardo drew a scale drawing of the school cafeteria. He used a scale of 1 inch: 6 feet. In the drawing, the width of the cafeteria is 9 inches long. What is the actual width of the cafeteria?
Answers
Answer:
54 feet
Step-by-step explanation:
the answer is 54 feet because the ratio of 1:6 is equal to 9:54.
Multiply both sides of your original ratio (1:6) by nine. 1x9=9 and 6x9=54.

The five-number summary for the data set is= 0,2.5, 3, 4,6.
What is five-number summary?The five-number summary includes the following
The minimum: The minimum which is the smallest is 0.Q1 (the first quartile, or the 25% mark):(0, 1, 2, 3,3,3,)3,(3,3,3,5,5,6)
Q1 = 2+3/2 = 5/2 = 2.5
The median: The median is 3 which is the number at the middle after being arranged from the lowest to the highest number.Q3 (the third quartile, or the 75% mark):(0, 1, 2, 3,3,3,)3,(3,3,3,5,5,6)
3+5/2= 8/2 = 4
The maximum: The maximum number which is the highest number is 6.
Therefore, the five-number summary of the data set=

Which of the following best describes the relationship between (x + 2) and
the polynomial 3x2 - x - 14?
A. It is impossible to tell whether (x + 2) is a factor.
B. (x + 2) is not a factor.
C. (x + 2) is a factor.
Answers
The factor theorem indicates that the expression (x + 2) is a factor of the polynomial, f(x) = 2·x² - x - 14, because, f(-2) = 0, the correct option is option C.
C. (x + 2) is a factor.
What is the factor theorem?The factor theorem, which is a unique example of the remainder theorem, indicates that the link between the factors and the zeros of the polynomial, such that (x - α) is a factor of the polynomial f(x), if and only if we get f(α) = 0.
The polynomial is; 3·x² - x - 14, the expression is; (x + 2)
The factor theorem indicates that we get, (x - a) is a factor of the polynomial of nth degree, where, n ≥ 1, if f(a) = 0
Whereby the polynomial is expressed as f(x) = 3·x² - x - 14 = 0, we get;
(x + 2), is a factor of the polynomial, according to the factor theorem, if we get, f(-2) = 0
Plugging in x = -2, in the polynomial, we get;
f(-2) = 3×(-2)² - (-2) - 14 = 0
Therefore, (x + 2) is a factor of the polynomial
The correct option is therefore;
C. (x + 2) is a factor

The monomial (x + 2) is a factor of the polynomial, the correct option is C.
How to find the relation?We want to find the relationship between (x + 2) and the polynomial:
P(x) = 3x^2 - x - 14
The monomial (x + 2) will be a factor of the polynomial only if x = -2 is a zero of the polynomial, so let's check that.
P(-2) = 3*(-2)^2 - (-2) - 14
P(-2) = 3*4 + 2 - 14 = 0
So -2 is a zero of the polynomial, then we the monomial (x + 2) is a factor of the polynomial.
The correct option is C.
