Answer: C

Step-by-step explanation:

Since there are 12 inches in 1 foot,

42 feet converts to 42 x 12 = 504 inches. If he makes a cut starting on one side, he will make 504/20 = 25.2 cuts. Since he won't make a partial cut, the answer is 25

Questions 16-17. Suppose a tortoise is 1000 feet from the ocean. Each day the tortoise travels three-fifths of the remaining dis

Soloha48 [4]

Answer:

r(n) = 1000·(2/5)^n

Step-by-step explanation:

Since the tortoise travels 3/5 the remaining distance, the remaining distance at the end of the day is 2/5 of what it was at the beginning of the day. So, the function can be modeled by an exponential with a "growth" factor of 2/5:

r(n) = 1000·(2/5)^n

where r(n) is the number of remaining feet after n days of travel.

Iman wrote the inequality x ≥ 12 to represent the money, x , that she has. Which situation below represents the amount of money

polet [3.4K]

Options :

Iman has at least $12.

Iman has more than $12.

Iman has less than $12.

Iman has no more than $12

Answer:

Iman has at least $12.

Step-by-step explanation:

The inequality x ≥ 12 represents the amount of money, x that Iman has :

The inequality statement can be interpreted as ;

x greater than or equal to 12, since x represents the amount Iman has ;

The the amount of money Iman has is $12 or more

Could also be interpreted as, ; Iman has at least $12

Answer:

$y=2.5x$

Step-by-step explanation:

We have been given a graph that shows numbers of servings (y) in different amounts (x) of frozen yogurt listed on a carton.

To write an equation that gives the number of servings y in x pints, we will have to find the slope (rate of change) of our given linear function.

Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.

$m=\frac{y_2-y_1}{x_2-x_1}$

m= Slope (rate of change).

$y_2-y_1$ =Difference between two y-coordinates.

$x_2-x_1$ =Difference between corresponding x-coordinates of the y-coordinates.

Upon substituting coordinates of two points (0,0) and (4,10) in slope formula we will get,

$m=\frac{10-0}{4-0}$

$m=\frac{10}{4}$

$m=2.5$

The slope of our given line is 2.5.

Now we will write equation of our given line is slope-intercept form. The equation of a line in slope-intercept form is: $y=mx+b$ , where m=slope and b = y-intercept (initial value).

Upon substituting m=2.5 and coordinates of point (4,10) in slope-intercept form of equation we will get,

$10=2.5\times 4+b$

$10=10+b$

$10-10=b$

$0=b$

Upon substituting m=2.5 and b=0 in slope-intercept form of equation we will get,

$y=2.5x+0$

$y=2.5x$

Therefore, the equation $y=2.5x$ will give the number of servings y in x pints.

Factories 6x +12y - 3z

Studentka2010 [4]

Answer: 3(2x+4y-z)

Step-by-step explanation:

To factor an expression, we want to take out the common factor within each term. In the expression, we know that 3 is a common factor because 6, 12, -3 are all factors of 3. When we take out a 3, we get 3(2x+4y-z).
