Mario walked at a rate of 5/6 miles every 10 minutes what is his unit rate every mile per hour

Answers

Answer:

Mario's unit rate is 5/1

Step-by-step explanation:

We know that Mario walks 5/6 miles per 10 minutes.

We need to find out how many miles Mario walks in 60 minutes (1 hour).

10 * 6 = 60. Which means that we must multiply 5/6 by 6.

[tex]\frac{5}{6} *\frac{6}{1} = \frac{30}6[/tex]

30/6 = 5

Mario walks 5 miles per hour.

To put this in to a unit rate we must put this is a fraction:

[tex]\frac{Miles}{Hour}[/tex]

Substitute:

5/1

Answer:

Mario's unit rate is given by 900 miles/hour

Step-by-step explanation:

We have been given that Mario walked at a rate of 2/3 miles every 10 minutes

We have the relation between speed, time and distance, which is given by

speed = distance/Time

we have,

distance = 2/3 miles

Time = 10 minutes

On substituting these values in above formula, we got

speed 2/3 /10

speed 2/10.3

We have to find the unit rate in mile per hour, so we need to multiply it by 60

Thus, unit rate is given by

1/15 X 60

= 4 miles/hour

6. Determine the value of x and y in the diagram below.
Show how you determined the value of x and y using Algebra

Answers

Answer:

y=43

X=34

Step-by-step explanation:

a) 2y+4=90

2y+4-4=90-4

2y=86. divide 86 by 2 to get y.

b) 3x-11=90

3x-11+11=90+11

3x=101. divide 101 by 3 to get X.

This table represents the number of ounces, u, a kitten grows after w, weeks. When graphed, all of the points in the table lie on the same line. What is the slope and y-intercept of the line? slope=−23, y-intercept=−0.2 slope=32, y-intercept = 3 slope=23, y-intercept=−0.2 slope=−32, y-intercept = 3

Answers

Using the slope and intercept formula, the slope and y - intercept values of the graphed data are 3/2 and 3 respectively

Given the data :

Weeks, w ___ Weight in ounces, u

0 __________ 3

3 _________ 7.5

6 __________12

9 _________16.5

The y - intercept :

This is the value of y when the value of x = 0

From the table given, the initial weight of the kitten (weight at week 0) = 3 ounces

Hence, the intercept is 3 ounces.

2.)

The slope :

Slope = Rise / Run

Rise = y2 - y1 = (16.5 - 3) = 13.5

Run = x2 - x1 = 9 - 0 = 9

Slope = 13.5 / 9 = 1.5

Therefore, the slope is 1.5
