Answer:

Unit rate = 20.8 ft/s

Step-by-step explanation:

We are given rate for 644.8 ft in 31 s

We need to find unit rate. We will calculate how many feet move in 1 second.

When rates are expressed as a quantity of single unit.

Such as 2 feet per second (It means in 1 seconds move 2 feet)

5 miles per hour ( In 1 hour move 5 miles)

We will calculate in 1 second how much feet.

In 31 seconds = 644.8 ft

In 1 second = 644.8÷31

Unit rate = 20.8 ft/s

25 POINTS!!! The equation y=470x represents the relationship between x, the time that a plane flies in hours, and y, the distanc
sineoko [7]

Answer:

Step-by-step explanation:

For plane A,

Equation that represents the relationship between time 'x' and distance 'y' is,

y = 470x

By comparing this equation with the slope-intercept form of the equation,

y = mx + b

m = slope = 470

b = 0

Here, slope represents the speed of plane A.

Therefore, speed of plane A = 470 mi per hour

For plane B,

From the given table,

Slope of the graph = \frac{y_2-y_1}{x_2-x_1}

                                = \frac{960-480}{2-1}

                                = 480

Speed of plane B = 480 miles per hour

Since, speed of plane B is more than plane A,

Plane B is flying faster.

7.19 divided by 58 estimate the quotients
lozanna [386]

Answer:

0.124

Step-by-step explanation:

\frac{7.19}{58}

To divide the numbers, we need to remove the decimal point

To remove decimal point , we multiply top and bottom by 100

\frac{719}{5800}

Use long division. After using decimal point at the top we can include any number of zeros with 719

                            . 1 2 3 9

                        ---------------------

        5800         7190

                          5800

                     ------------------------(subtract)

                          13900

                          11600

                       ---------------------------(subtract)

                           2300 0

                           1740 0

                       --------------------------(subtract)

                            56000

                            52200

                       ---------------------------(subtract)

                             3800 0

Division goes on ............

Estimate the quotient to 3 decimal places

Quotient = 0.124
