Mary sews at a rate of 60 inches per hour. How many feet does she sew in a minute?
makvit [3.9K]

Answer:

B. 0.083 rounded to the nearest thousandth.

Step-by-step explanation:

It is known that 12 inches = 1 foot and

60 minutes = 1 hour

Since we want to covert from inches per hour to feet per minute, then we would change 60 inches to feet in 1 hour 2 minutes in divide.

If 12 inches = 1 foot, then

60 inches = 60/12 = 5 feet

Therefore, the number of feet that she sews in a minute is

5/60 = 0.083 feet per minute

She sews 0.083 feet per minute.

This is the full explanation for this question.

Which equation could represent the relationship shown in the scatter plot?
Allisa [31]
Y = mx + b, where m is the slope, and b is the y-intercept. If we were to consider a line of best fit that would represent all these points with a linear line, it'd cross the y-axis with a y-value of 10, so we can fill in y = mx + b to y = mx + 10. Now, it runs down from left to right, so we know the slope must be negative. The only equation that fits this description is y= -3/4x + 10

Hugh bought some magazines that cost $3.95 each and some books that cost $8.95 each. He spent a total of $47.65. If Hugh bought
kozerog [31]

Answer:

4 books

Step-by-step explanation:

Our problem here is:

(3.95)3+8.95b=47.65

So we have to find B, and that will be our answer (the number of books).

1. Simplify the expression

3.95\cdot 3+8.95x=47.65

Combine like terms:

11.85+8.95x=47.65

2. Group all constants on the right side of the equation

11.85+8.95x=47.65

Subtract  from both sides:

11.85+8.95x-11.85=47.65-11.85

Group like terms:

8.95x+11.85-11.85=47.65-11.85

Simplify the arithmetic:

8.95x=47.65-11.85

Simplify the arithmetic:

8.95x=35.8

3. Isolate the x

8.95x=35.8

Divide both sides by 8.95:

\frac{8.95x}{8.95}=\frac{35.8}{8.95}

Simplify the arithmetic:

x=\frac{35.8}{8.95}

Simplify the arithmetic:

x=4

<h2>Hence, the number of books is 4</h2>
