Margie hiked a 17 7/8 mile trail.She stopped every 3 2/5 miles to take a picture.Which is the best estimate of the number of times she stopped ? A 4. B 6. C 7. D 8.

Answers

Answer 1
Answer:

Answer:

Option B is the correct answer

Step-by-step explanation:

Margie hiked a 17 7/8 mile trail.

\texttt{Distance hiked by Margie = }17(7)/(8)=(17* 8+7)/(8)=(143)/(8)mile

She stopped every 3 2/5 miles to take a picture.

\texttt{Distance at which she stopped to take picture = }3(2)/(5)=(3* 5+2)/(5)=(17)/(5)mile

\texttt{Number of pictures taken = }\frac{\texttt{Distance hiked by Margie}}{\texttt{Distance at which she stopped to take picture}}\n\n\texttt{Number of pictures taken = }((143)/(8))/((17)/(5))=(715)/(136)=5.28

So she can take maximum of 6 picture and minimum of 5 picture.

Option B is the correct answer
Answer 2
Answer: 17 7/8÷3 2/5
143/8÷17/5
multiply by reciprocal
143/8×5/17= 715/136= 5.26 which is closer to
B. 6

The length of a rectangle is 4 times its width and the perimeter is 150 feet. What is the width of the rectangle?

A.
75 feet

B.
30 feet

C.
15 feet

D.
60 feet

Answers

We know that L = 4W, and P = 2l + 2w, so 150 = 2L + 2w
So, 150 = 2*4w + 2w
      150 = 8w + 2w
      150 = 10w
       w = 150/10
       w=15
So, the Width of the Rectangle is 15 feet.
And if they asked you to find the length,
 L = 4W
L = 4*15
L=60 
so, the Length will be 60 feet.

Hope this Helps! :)

This table shows a linear relationship. x 3 4 5 6 7 y 14 18 22 26 30 Based on the information in this table, which equation can be used to model the relationship between x and y? Responses y = 4x + 2 y, = 4, x, + 2 y = 2x + 4 y, = 2, x, + 4 y = 4x y, = 4, x y = 2x

Answers

Answer:

Step-by-step explanation:

y = mx + b

Where:

y is the dependent variable (in this case, the values in the "y" column).

x is the independent variable (in this case, the values in the "x" column).

m is the slope of the line.

b is the y-intercept (the value of y when x is 0).

We can calculate the slope (m) using two points from the table. Let's use the points (3, 14) and (7, 30):

m = (y2 - y1) / (x2 - x1)

m = (30 - 14) / (7 - 3)

m = 16 / 4

m = 4

Now that we have found the slope (m), we can determine the equation:

y = 4x + b

To find the y-intercept (b), we can use one of the points from the table. Let's use the point (3, 14):

14 = 4(3) + b

14 = 12 + b

Now, solve for b:

b = 14 - 12

b = 2

So, the equation that models the relationship between x and y in the table is:

y = 4x + 2

Therefore, the correct equation is: y = 4x + 2.
